What is a Projector Lamp?
The technical description of a projector lamp is that it is an ultra-high pressure mercury vapor ARC lamp. Projector lamps
are scientifically categorized as metal halide lamps andPhilips has trademarked the name "UHP lamp" for their
projector lamps.
How Does a Projector Lamp Work?
A projector lamp operates by sending an electrical current accross an ARC gap that is full of
ultra-high pressurized mercury vapor. The electricity lights the mercury vapor which then causes
the lamp to emit a light with an extreme intensity or brightness. The bright light created by this process shines onto an
LCD (Liquid Crystal Diplay) or DLP panel which then in turn produces the fantastic images projectors are known for.
Projector lamps are a extremely complex technology that are very costly to manufacturer, therefore the price of
projector lamps tends to be pretty high.

Replacing a Projector Lamp
Projector lamps are easy to replace whether you have the bare projector lamp only or the projector lamp in the black
plastic housing.

How Do I Know When My Projector Lamp is Dead?

Often times projectors will have a built in timer that keep tracks of how long your projector lamp has been running inside

your projector. Once the timer reaches a certain point, usually a few hours before the expected lamp life, a message will

display on your projector screen. The warning message is usually a good indicator that you should jump online and start

looking for new projector lamp.

It is possible to get rid of the warning message, you can do this by searching your projector's manual or navigating through

the onscreen menu if your lamp is still functioning.

Sometimes projectors will shut the projector lamp down when the timer reaches a certain point, even if it has not been totally

exhausted. In these cases, it is useful to reset your lamp hour counter as it may increase the amount of life you get from your

projector lamp.

We recommend that if you are using your projector lamp for important presentations, weekly events or even home theater that

it is smart to have a back-up projector lamp in stock so that you will not miss a minute without your projector.

Projector Lamp Compatibility

Can I Put Any Lamp in  My Projector?

Projector lamps are manufactured to specific settings, meaning the mercury vapor is pressurized to a precise measurement and

the quartz ARC tube is engineered to withstand that pressure.

This means that the projector lamp manufactured for any specfic projector or group or projectors is unique to those units only. You

cannot, for example, put a 150W projector lamp inside a projector that requires a 250W projector lamp. It is also impossible to put

a 250W projector lamp inside a projector that requires a 250W projector lamp but nonetheless requires a different ignition and

running voltage.

Projector lamps also have different ANSI lumens rates or brightnesses. If you install a lamp with the same ignition and running

voltages AND the same wattage settings but a different ANSI lumens rate then the projector will not perform as it is supposed to.

Are Any Projector Lamps Compatible with Multiple Projectors?

Yes! There are several projector manufacturers who frequently team up and license the same, exact projector lamp from a single

projector lamp manufacturer.

Extending Projector Lamp Life

Projector lamps usually expire early because they are burning at too hot a temperature over the course of their lives. Below

are some simple tips for extending your projector lamp life.

Ventilation -

The single most important thing you can do to make sure your projector lamp lasts a long time is to mount your projector in

a space with ample ventilation. Projectors that are mounted in corners, extremely close to the ceiling or in rooms with little to

no air flow often cause the projector lamps inside them to expire early.

Vacuum and Blow Compressed Air -

Dust that gathers inside your projector can cause the projector lamp to burn at too hot a temperature over time which will cut

its life short. The easiest solution to this problem is to vacuum your projector and blow it out with compressed air every now

and then. Use your judgment, if you are using the projector often, complete this process more frequently.

Change or Clean Your Filter Regularly -

Almost every projector these days has a filter that prevents dust from getting inside the sensitive circuitry. The drawback to this

is that if the filter gets clogged with dust it can cause the projector lamp to burn at a hotter temperature and diminish its lamp

life. The filter on your projector is usually found behind a small rectangular panel that measures 0.5" by 6" long.

Do Not Turn Your Projector On and Off Quickly -

Turning your projector on and off quickly can have devastating effects for your projector lamp. Projector lamps typically take

about a minute before they are running in a stable current. Projectors have special ballasts inside them that ignite projector

lamps at a high voltage and then run them at a low voltage. If you turn your projector on and off quickly it can cause the

ultra-high pressurized mercury vapor to become destabilized, which will in turn cause your projector lamp to fail permanently.

Run Your Projector in Economy Mode -

Most projectors these days have normal mode and economy mode. Economy mode usually makes the projector lamp emit a

slightly lower brightness level and therefore can extend your projector lamp's life. If you are unsure if your proejctor has economy

mode, please reference your projector's manual or contact the manufacturer.

Testing a Projector Lamp

Projector lamps are a complex and different technology than most household or traditional electronics and therefore it is important to

know certain facts when attempting to test a projector lamp.

1. Projector lamps use customized ballasts that ignite the lamp by charging it with a higher voltage in the ignition phase and then

dropping down to a lower running voltage once the circuit is created.

2. Projector lamps CANNOT be tested with an AMP or OHM meter. Projector lamps function by igniting ultra-high pressurized

mercury vapor accross an ARC tube. At the point where the mercury vapor resides there is no conductive electrical material and

therefore testing a projector lamp with an AMP or OHM will not work.

Projector Lamp Anatomy

A projector lamp is made up of several components including the ARC tube, ultra-high pressurized mercury vapor, electrical

wiring, a quartz globe or reflector, a fastener, a spoke, a bolt, a screw and finally the black plastic housing itself.

ARC Tube -The ARC tube is a piece of blown quartz measuring about 2 inches in length that protrudes up from the base of

the quartz globe. The ARC tube is positioned by highly-accurate machines and then set with extra strength plaster.

Mercury Vapor -The mercury vapor inside most projector lamp ARC tubes is ultra-high pressurized. The mercury vapor is

sensitive to the amount of current running through it and so projectors have electrical

ballasts inside them to regulate electricity flow. The ballasts ignite the mercury vapor at a high voltage and then bring the voltage

level down to the apropriate running voltage required to sustain the projector lamp.

Electrical Wiring - The electrical wiring on a projector lamp is fused inside the quartz ARC tube and runs out the top of the

tube through the side of the reflector. Electricity from the projector and regulated by the ballast runs in a circuit from the back of

the projector lamp through the side and back into the projector.

Quartz Globe - The quartz globe or reflector as it is sometimes called, is the hard exterior skeleton of a projector lamp. The

quartz globe is usually

lined with a highly reflective metal material on the inside that reflects light generated by the ignition of the mercury vapor inside

the ARC tube. The quartz globe also holds the ARC tube in place and is usually filled with extra strength caulking in its base to

complete this task.

Fasteners, spoke, bolt and screw -Projector lamps are connected to wiring that runs current to and from the projector. The

wiring is attached to the projector lamp by way of a fastener, a spoke, a bolt and a screw.

The fastener is a small metal piece that is either glued, sodered or clamped onto the side of the projector lamp. The fastener

receives the screw that in turn holds one of the wires in place against the fastener .

A spoke is connected to the ARC tube and is usually cemented in place at the back of the lamp. The spoke usually protudes

about an inch and a half and receives the bolt which holds the second wire in place, enabling the projector lamp to complete

the circuit.
Plastic Housing - The plastic housing is the piece of molded plastic that holds the projector lamp in place when it is sitting
inside the projector.
Projector lamps are usually locked into the plastic housing using a retaining clip. The attached wiring easily screws into a slot
at the back of the plastic housing.

投影仪使用方法和注意事项
1、开关顺序不能错 2、不能频繁开关机 3、防震 4、防尘

在使用投影机时,一定要养成良好的使用习惯,以免投影机在你不正当的使用情况下,提前退休。

1、开关顺序不能错:正如计算机有严格的开关流程一样,投影机对开关机的要求比计算机的要求更加严格。因为错误的操作步骤会对投影机造成极大的损害。正确的操作流程如下:

开机:按Power键接通电源,持续按住投影机面板上的“Lamp”指示灯,直到绿灯停止闪烁。
关机:持续按住“Lamp”指示灯直到绿灯不闪以及投影机散热风扇停止转动,这时再关闭电源。

2、不能频繁开关机:投影机内部有许多光学器件,它们对电流大小有严格限制,一旦出现电流不稳定或者有较大冲击电流时,很容易损坏。为了避免这些器件受损.不要频繁开关投影机,因为开关投影机时,会产生较大的冲击电流,而投影机内部的光学器件在多次受到冲击电流的撞击后,寿命会大大缩短。日常使用中,一般在关闭5分钟后再次开机。详情致电:021-51876O3O

3、防震:无论是3LCD投影机还是DLP投影机,都是高精度、高灵敏度的产品,最忌讳的就是震动和撞击。这对于吊投等固定式安装的投影机可能问题不大,但对便携式、桌面式投影机就需要注意了。光学系统的镜头差之毫厘,投射出去的影像就会谬之千里,严重影响显示质量。3LCD投影机的液晶板如果受冲击太大而导致移位,影像的聚焦和色纯就会受到严重影响。尤其要注意的是投影机刚开机和关机时切忌随意挪动,否则很容易导致投影机的周边元器件过热而损坏,更有可能对灯泡寿命产生不良影响。因为此时光源灯泡正在点亮,灯丝处于半熔状态,震动很容易造成灯泡炸裂。大多数投影机都使用金属卤素灯,处于点亮状态时,灯泡两端的电压一般在60~80V,而温度则高达上千度。因此按下关机按钮后,散热风扇仍然会高速旋转,这是出于保护投影机而特别设计的。待温度降低后,风扇自动停转,这时才能拔掉电源。

4、防尘:任何精密光学设备都害怕灰尘,投影机也不例外。哪怕是很小的一粒灰尘,都会对投影影像造成极大的影响。而且.投影机内部的清洁非常困难,在一般环境下打开机壳,有可能会带来更多的灰尘影响。因此,应该保证投影演示场所的通风和洁净。在投影机底部风扇进风口有一个灰尘过滤器,时间久了,过滤器会被堵塞,影响机器的通风和冷却,会因此而产生故障。所以投影机使用一段时间后(比如一个月左右),就应该把过滤器清洁一下。投影机要定期进行除尘工作(比如一年两次),以提高灯泡、LCD、偏振板的使用年限,降低这些设备的更换频率,最终节省后期使用成本。并且每月定期清洗投影机过滤网,可以降低做光路除尘的次数。特别要说一下光路除尘:它一定要由专业工程师操作,因为普通用户一旦操作不当,破坏了LCD片的定位,很难恢复,所以做光路除尘是有风险的,不建议非专业人员使用。

总之,定期对投影机进行保养工作是非常重要的。这样可长久保持投影机外表的干净,同时也可防止一些灰尘污染内部敏感组件及镜头等,以免影响投影画面的质量。还要提醒大家的是:在进行以下的清洁工作前,需要让投影机进入待机模式,待从交流电插座上拔下电源线后,才可进行。详情致电:021-51876O39
