What Makes a Projector? -DLP

Projectors have come a long way over the years.  At first they used film to feed through a mechanical shutter with the 2 large reels holding the film. Now they have become stand alone display devices.  More similar to a TV screen than a slide projector.

What makes them what they are today? There are essentially two answers to that question.  One is LCD technology and the other is DLP technology.  They both use replaceable lamps, but how they use those lamps to create the image is what sets them apart.

This begins a short series on Projector display technology.  This post we will cover DLP Projectors.

DLP is an acronym for Digital Light Processing. Invented in 1987 by Larry Hornbeck of Texas Instruments the digital mirrored device chip(DMD).

The first video projector to use this technology was built by Digital Projection in 1997.  Both Digital Projection and Texas Instruments won an Emmy Award for the use of DLP technology.

A DMD chip(pictured above) is made up of microscopic mirrors arranged in an array on the chip surface.  The mirrors are controlled via small electrostatic pulses to adjust their angle.  The angle causes them to either reflect the light out the lens onto the screen or away from the lens to create black or lack of light.  Each mirror is made up a microscopic yoke, torsion spring, and the electrostatic pads that affect the memory cells that set the position.

The diagram to the right shows the construction of each pixel.  Depending on the resolutions the amount of pixels changes. For instance an 800 x 600 DMD has (800*600 pixels= 480,000) pixels or mirrors that are controlled.  However some chips use a method of oscillating the mirrors to have them act double duty, halving the amount of mirror elements needed in a DMD chip.  

DLP Chips are monochrome or single colored. They can only turn light on and off and adjust its brightness. It cannot color the light.  This is where the next most important device of a DLP projector comes into play.

The Color wheel is a glass wheel made up of multiple segments all with a different color glass light filter.  On average they use 4 segments: red, blue, green and clear. Some models have multiples of the same color.  Others use 6 segments colors red, purple, blue, light blue, green and yellow.  The projector syncs the rotation of the color wheel and the color needs of the DMD while the image is being projected. DLP uses optical persistence to "fool" our eyes into seeing a mix of colors when in reality the projector is only projecting one color at a time for a fraction of a second.  If you blink your eyes quickly while looking at the DLP projected image, you can see the colors by themselves.

These 2 devices more than any other set the DLP projector apart from LCD.  Other differences are in the electronics.  There are a whole set of electronics that only are there to support and control the DMD chip.  These electronics are not as physically obvious but are no less important. These chips are for driving the electrostatic control signals to the DMD, as well as the video processing chips that prepare the signal to the DMD controller.  There is a motor control chip that keeps the color wheel in sync so that why the DMD is projecting the red portion of the image, the red color wheel segment is in position.  These all work together to ensure a pleasant and vibrant image.  

The main benefit of DLP over LCD(at the time) was the contrast ratio. Contrast ratio is the difference between a full white and full black image. When using a lamp to create an image there is almost no chance of having true black as black is the absence of light.  Turning off the lamp for the black portions of the picture is not practical.  Rather the pixels that require black merely point their light away from the main lens creating black on the screen.  Since the mirrors are only pointing away, there is some minor light leakage so the "blacks" are not as black as they could be.  The higher the ratio, the darker the blacks and brighter the white bits of the image will be. This was more of an issue with DLP first came to market as LCD had abysmal contrast.  These days they are pretty much the same contrast ratio-wise.

The last and most obvious difference is the lamp used in DLP.  Both DLP and LCD use Short ARC Mercury vapor lamps but only DLP uses this particular arrangement.

DLP Lamps commonly use a non-optical lens. Meaning there is no focusing or change in direction of the light beam.  Rather they have lenses inside the optics that do any light adjustment needed.  The lamps do have a special coating on the lens(ND filter lens). That coating prevents UV(ultraviolet) and IR(infrared) light from being injected into the light path.

DLP Lamp with UV/IR coating

LCD LampThese can harm your eyes and the optics due to heat and radiation.  This coating is a big reason why we do not recommend replacing only the bare bulb. If that coating fails or fails just a little it can cause your color wheel problems and possibly even melt some of the lenses.

Here is a picture of the internals from a Polyvision PJ905 that uses a 2002031-00 Lamp that has the proper coating.

PJ905 Internal diagram of DLP projector.

This about sums up the DLP video projector.  They are a reliable and well proven piece of technology.  Pureland Supply takes a lot of pride in our lamps and we make sure every lamp that is used in a DLP projector(as well as LCD) is configured correctly to perform as well as possible for you.  Check our selection of lamps here.

Congratulations to the Philadelphia Eagles..and your Projector!

Congratulations to the 2018 Super Bowl winners, the Philadelphia Eagles! 
2018 Super Bowl Champs Eagles

Being a company based out of the Philadelphia area, we have a lot of Eagles fans who work here.

While New England played hard, it was nice to see the Eagles play a little harder.  The same can be said for your video projector.  Each projector is an engineering marvel that balances cost with function.

Think of your lamp like the Quarterback.  The lamps job is to pass light through the optics to the end-zone/screen.  Your lamp is constantly at odds with elements looking to make it fail.

Heat and dust are working hard to chip away at your lamp life, but the supporting members of your projector team work to protect it. The cooling fans are the Lamp's Guards, while the filter is the Lamp's Fullback. The rest of the team has its own purposes to ensure long life and clear pictures of your projector.

With the Football Season over for now, its a great time to start planning for next season.  4K projectors are becoming more reasonably priced and their lamps are some of the brightest to be made yet for the price range.

You can use the next few months to decide the best course of action to install your new projector or put your old projector into "pre season training" by making sure its been cleaned and replacing your lamp if its nearing the end of its life or starting to look dim. Its better to change your lamp before it fails.  You can save the old one as a back up and return the unit to its original brightness.

If you are looking to upgrade a good example is the BenQ HT2550 projector.

BenQ HT2550 Projector 4K
This is a true 4K (3840x2160)model rather than an enhanced 1080p (1920 x 1080)Projector like the Home Cinema 4000 .  The BenQ HT2550 retails for around $1,500.  Unlike the Sim2 Crystal 4 UHD which is 10x the price.

The BenQ projector has almost the same specs as the Sim2.  While Sim2 is a fantastic brand, it is not the most affordable and is not an entry level of average consumer level unit.
Sim2 UHD $15,000

Pureland Supply offers a lamp for each of these unit.  You can search for this BenQ or your model BenQ via our Manufacturers page.  It lists every model and lamp for you to browse through, or you can use the search function to find your specific model or lamp number.

Of course if you are unable to find the model you are looking for or have any questions at all, our team at PurelandSupply is ready to help you with any of your projector lamp questions.

Give us a chance to support your projector for the rest of 2018. Contact us at 1-800-664-6671 via Phone or Online Chat Monday-Friday 9am to 5pm Est. We can also be contacted via email 24/7 at

6 Steps to Change Your Projector Lamp

Here are 6 Basic Steps for Lamp Replacement. 

You should always refer to the owners manual for the proper specific steps but if you have a pretty basic Projector or Rear Projection TV, these steps should get you back up and running.

    1. Preparing the Projector to Be Opened
Before attempting to open the projector, users should turn off and unplug the device. They should also allow the device to cool down. It could take anywhere from 30 to 45 minutes for the projector to cool down completely. Then remove any dust on the outside casing with a soft, dry, and clean cloth. This will ensure that dust does not enter into the machine and get onto the vulnerable interior parts.

2. Remove Lamp Access Door
Some projectors may have covers that come off completely while other models just have a smaller compartment door that gives users access to the lamp housing unit. Projector owners can determine what kind of opening they have by looking at the projector and consulting the manual. 
No matter what the cover or the compartment door must be opened.  You will most likely need a screwdriver to remove the screws that keep the cover or door closed. Once the screws have been removed, you can carefully remove the panel or door. You should also take the time to unscrew any screws that may be keeping the housing unit of the lamp in place before attempting to remove it.

3. Taking Out the Old Projector Lamp 
This is a step that users must take care to complete properly. Doing otherwise may cause the old projector lamp to burst, which is dangerous for both the projector and the user. Because projector Bulbs inside the lamps are very fragile.  They can burst after starting because they have come into contact with the natural oils that are present on fingers.  this causes the glass of the bulb to expand at different rates when it heats.  For this reason you should always use the handle on the lamp to pull it out.  As an example the Christie 003-120507-01 
lamp has two points on the bottom to grab the lamp for removal.

4. Putting In the New Lamp
Once the old lamp is removed, the user can then place the new lamp housing unit inside of the Projector/TV. Users should make sure to slide the housing unit fully into the projector, with the new lamp in the same position that the old one was in. Certain projectors may require that power cables be reconnected to the new lamp. If this is the case, users should follow the manuals for specific instructions on how to do this.

5. Getting the Projector Ready to Run Again
   When the switch has been made, you can screw the new lamp housing unit into place and then re-attach the lamp access panel. Be sure to not over-tighten the screws.  At this point, the users can reconnect the projector to the electrical outlet and turn on the project to see if the new lamp works. If the projector still does not work after the lamp replacement has been made, there may be a larger issue that is causing the problem. In this case, users should seek the help of professionals specializing in projector repair in order to determine the right course of action.

6. Resetting the Lamp timer
If the projector is working properly, then the user will need to reset the lamp counter so that it can begin tracking time for the new lamp that has just been installed. Some projectors might reset lamp counters automatically, but for those that do not, users may need to do this manually through the projector menu. After completing all of these steps, the projector should be ready to provide hours and hours of entertainment once again.

If at any point you are uncomfortable or unable to perform these steps, please do not hesitate to contact our world class customer service department for assistance.  We have one of if not the best trained representatives to help you with your problems.

10 Tips to Prolong Lamp Life from Pureland Supply

Projector lamps are most important to your projector. Prolong their life with these tips.

1.  Handle the Projector Lamp with gloves. Oils and deposits from hands and fingers can cause hot spots on face of the Projector Lamp, which may result in premature Lamp failure.  Gloves also insure against any smudges that could get on the glass lenses or the projector or the lamp itself.

2.  Operate your projector in a clean, cool, and well ventilated area. A dust free environment would be ideal.  It may be advantageous to look into a ventilation system or air filtration system in the area that the projector will be operating in.

3.  Keep the projector air filters and air vents clean. Clogged filters/vents will not remove heat effectively. This can cause the projector to overheat with an early lamp failure.  During routine maintenance it is recommended to vacuum any loose debris and dust from the projector.  You can also get a can of sealed air to blast out any small particles and dust from the air vents and filter.

4.  Do not place anything on top of the projector or in front of the intake or exhaust vents. This will cause the projector lamp to overheat and fail. Refer to your manual for safe placement of the projector and the accessories.  The vents should be operating in an unrestricted environment that has strong air circulation.

5.  If the projector is built into a compartment, wall, ceiling, or shelf mount, the minimum distance requirement is usually at least 2 feet.  This allows enough space to dissipate any heat that will build up.  Refer to your owner’s manual for specific recommendations.

6.  When you replace the projector lamp make sure the new housing is seated completely and securely. Pureland Supply continually gets phone calls and inquiries from customers that think they have a defective lamp when in actuality they simply didn’t push the lamp in far enough.  Pay attention to the old lamp. Re-install and remove the old lamp a few times to get familiar with the how it fit into your projector. When you install the new lamp you can seat it firmly but without too much pressure.  Use the screws to tighten the lamp into its final position.

7.  Hot Projector Lamps are fragile. Do not move or shake the projector until the Projector Lamp has completely cooled. Shock and vibration applied to hot projector lamps may cause the lamp to break or shorten its effective lifespan.  It is recommended that after operation you let the lamp cool at least an hour before handling the projector or lamp.

8.  Do not unplug the projector until the Lamp has properly cooled. After the projector has been shut off, the fan will remain on for a period. This is required for proper cooling of the lamp.  If the lamp is not cooled properly it will cause the life of the lamp to be shortened drastically.  This is a critical point where many people unplug their projector during use in order to turn it off.  By doing this the lamp is extremely hot and has no air circulation resulting in damage or shortened life of the lamp.

9.  Do not turn the projector on and off frequently during presentations. Each time the projector is switched on, the inrush of power causes stress on the Projector Lamp as does the thermal cycles (heating cooling). Try to minimize your on/ off cycles by not frequently turning on and off. If you are not using the unit for less than 30minutes, use a screen saver or video mute option that some models offer.

10.   Wait until the fans stop running before attempting to turn a projector back on after use. Forcing the Projector Lamp to start before it is adequately cool will cause a thermal and electrical shock to the bulb causing the life to be shortened.

It is recommended that you have your projector serviced and maintained approximately every 2 years.

Preferably have the projector cleaned for dust buildup seasonally.

Insist on high quality projector lamps with the original manufacturer’s bulb inside (Made by Philips, Ushio, Phoenix, or Osram).  All lamps are available for sale at PurelandSupply

Is My Projector Ready for the Holidays?

Unless you are me or involved in the home theater hobby I doubt this is a question you ask yourself. 

However, if you entertain regularly over the holidays it’s something worth considering.  Over the course of the year your projector is pulling a lot of air through it.  That air is used to cool the electronic components as well as the lamp.  Unless you are fortunate enough to live is a sterile environment you will get dust pulled inside with that cooling air.

Over time that dust builds up. That dust can start to prevent the air from cooling.  Once the dust builds up to the point to where it isn’t being cooled anymore and will start to act like insulation keeping the heat in.

Depending on your model, removing that dust can vary.  You always hear, “clean your projector”.  Sure, wipe the outside down and keep that machine looking nice. 

However, there is an entire world going on inside your projector.  Fans, ducts circuit boards Oh My! These all tend to gather dust regardless of how clean your house is.  Electronics in general tend to attract dust due to their nature.

There are many models that use filters.  Those filters vary from a complicated cartridge type that is consumable and requires replacement.  Then there are others that use a simple foam rubber filter on a carrier frame.  More recently the filters have been abandoned for under $1000 models. Instead opting for large open airways to channel the dust in and out rather than filtering it.

Short lamp life is the first symptom. More specifically a progressively shorter lamp life. Each lamp will run but maybe it fails after 500 hours. The next lamp fails after 200 hours.  These hour ratings are examples of course. You may see 1000 hours or more but no where near your original lamps life span.

This particular projector below uses a BL-FU310A which is on sale here. Once you clean your projector your BL-FU310A will run cool and bright.

Here are some examples of what your projector may look like inside if it has never been internally cleaned. Have it cleaned regularly to prevent failure during the holidays. Let us know if you have any question at 1-800-664-6671 or

Here is the side of the DLP Chip Heat-sink.

This is the main cooling Fan. Not moving much air.

Here is an overview of the entire projector’s electronics. That dust will cause heat problems.

This is the ballast. That powers the bulb. With this much dust it overheated and failed. Needed to be replaced, with a repair cost in the hundreds of dollars.

We do offer a Professional Cleaning Option. If this is something you would like to learn more about, please contact us with any questions. - PurelandSupply  1-800-664-6671 /

The weather is getting colder, the holidays are fast approaching, and the time to get prepared is now! Make sure your projector is performing at its best by giving it a thorough semi-annual cleaning. Even if the projector is not used frequently this cleaning can still aide in prolonging the life of your projector. Dust build up occurs whether the projector is used routinely or not, and the following check list can help to guide you in the cleaning process.
For a full, detailed maintenance procedure ALWAYS make sure to check your projector manual. When cleaning delicate electronics use short bursts of canned air to dislodge any debris (while taking care to not push the dust into the projector further), and then use a vacuum attachment to pull out any dust blockages.
-> Locate & clean the filters (if equipped)
-> Clean all intake and exhaust vents
->Remove the lamp assembly and clean the lamp compartment
-> Remove dust from the fan located by the lamp compartment
-> Using a soft cloth wipe down the casing and lens of the projector
-> Check the lamp hours in the OSD menu
Time flies in today’s world, so make sure you are ahead of the game. Starting now will give you plenty of time to get everything accomplished, and to order a new lamp if your current one is starting to look dim.

What to Do if Your Lamp Stops Working...

...or if your new lamp does not work read these to see if they can help you.

I installed my lamp and now it won’t turn on. Do I have a defective lamp?

There are a few things to check before contacting customer service that may rectify the situation.
·         Make sure your projector is plugged back in.
·         Is the lamp cover fully secured back into place? The projector will not turn on unless it recognizes this access door is closed.
·         It is always best to unplug the unit when replacing the lamp, so make sure it’s properly plugged into a good power outlet. Maybe unplug and re-plug in the projector to be sure.

My projector is plugged in, but I still am not getting light!

     Listen to the projector when you turn it on.  You should hear the exhaust fans after you press the power button for at least a few minutes while the unit tries to start the lamp.  If you do not hear the fans, it could be an indication that the lamp is not seated properly or the lamp access cover is not secure.  Remove and re-install the lamp and carefully replace the lamp cover.  If you still cannot hear any fans, check your power cord and then check to see if there are indicator lights flashing on the projector.
   If you can hear the fans running and there is still no picture, check for any flashing/solid indicator lights on the projector. These lights are how the unit tells us what is going on within the projector, and has a corresponding reference in the owner’s manual.
  Every projector has an owner’s manual available on line for free.  Check the flashing indicator lights against the description in the owner’s manual.  If the description points to a failed lamp, please contact our Customer Service for further assistance.

My lamp is projecting a picture, but I have a message telling me to replace the lamp.  This is a new lamp, why is it saying that?

     Most Projectors have a Lamp Hour Counter or Lamp Timer to keep track of lamp usage.  The units are designed to warn you when the lamp is approaching the end of its life.  When a new lamp is installed, you must manually reset the timer or the projector will not know the lamp has been changed and will count an incorrect amount of hours.  This also means that if you prematurely reset the timer, you will not have a proper hour count on the replacement lamp once installed.  Some projectors will turn off completely and need to be manually reset before they will turn on if the lamp hours are exceeded beyond the factory settings.
- It is always a good idea to check the manual and reset the timer as instructed.

My projector is much dimmer than I would expect with a new bulb. Do I need to send it back?

     Check to make sure the bulb is installed flush with the front of the housing.  It should sit exactly as the old bulb and must be installed the same way or the light will not illuminate the image correctly. Should the bulb be slightly off center, or not aligned correctly the image can be dim, and you will need to contact PurelandSupply for a Return Authorization (RA) Form.

My projector turns on for a few minutes and turns off after installing the new lamp.

     While this could be a defective lamp, it is common for many Projectors to turn themselves off when there is another issue.  Many times the fans will be dusty and not spin correctly.  That will cause the projector to shut down.  Try cleaning the projector with a vacuum to make sure as much dust and dirt is cleaned up as possible.

I installed the lamp and my projector is telling me that it is getting too hot.

     Anytime you replace your lamp, it is a good idea to clean the unit for dust.  Heat is the primary cause of early lamp failure.  By keeping your TV/Projector clear of dust, you will help it keep the lamp at a proper temperature.  While the lamp is out, use a vacuum cleaner to collect any dust from the lamp compartment and the vents so that it does not re-collect in the TV/Projector.
     This is recommended to be done at least when the lamp is changed, but once every 3-4 months is even better.  With proper maintenance of the TV/Projector, the longer it will last.

I received my lamp but it is not the same as the one I removed.

     It is very rare that there can be multiple lamps for a Projector.  Occasionally the manufacturer will switch lamps mid production, which can be confusing and frustrating. This can be resolved very easily with some help from you.  Record any numbers on the lamp/bulb.  Also verify your model # as well as any letters before or after the model number.  Contact our customer service with the information from your old lamp/bulb and we can correct your order and have the issue taken care of.

My projector has a new lamp, but the color of the screen is still wrong.  I see colors where they shouldn’t be and the picture is either flickering or off color completely. Is my lamp defective?

     Our lamps only project a bright white light.  Your Projector processes the color control by shining the white light thought either a color wheel for DLP or LCD panels for LCD units.  The color can only be affected by the internal optics of the projector.  Generally an off color display will not be noticed with an older lamp as it is not operating at full power. With a new lamp, it will be brighter and show any issues that may have been there previously with a lot more clarity.  A new lamp will NOT resolve this as the issue is with the internal optics.

I do not see the answer to my issue.  Is there anyone I can talk to?
