There are several types of projector light source, life cost energy consumption each how

Lamp as the only consumable material of the projector, is an important factor that must be considered when buying a projector. Currently the projector is commonly used in the projector is a metal halide bulb, UHE bulb, UHP bulb these three light sources. It is recommended to purchase a projector that uses UHE and UHP cold light sources, which will effectively protect your projector while saving your investment.

In addition, special attention should be paid to: different brands of projectors using the lamp is generally not interchangeable, so the purchase of the projector should choose to buy a well-known domestic companies selling well-known brands of projectors, so as to avoid running out of bulbs due to the inability to buy the right bulb caused by the projector's scrapping.

The bulb is an important consumable in the projector, it is more expensive, how to effectively protect the bulb is every projection operator, must be taken seriously. To this end, this article puts forward five recommendations to ensure that everyone with a good bulb.

1, the switching interval should be about 5 minutes

Because the projector power supply uses a proportional pulse-width modulation method of utility voltage reduction and voltage stabilization, power stabilization, and in the processing of these links, the projector power supply power switching tubes and transformers will be working at a higher frequency, switching tubes in the frequent switching process will be very naturally occurring a considerable amount of switching losses, these losses will be the projector power supply. Switching loss, these losses will be transferred into heat emitted, thus making the projector internal temperature rise, coupled with the bulb itself issued by the heat gathered in the small space inside the projector, it will be very easy to make the bulb to produce the explosion phenomenon. In addition, frequent switching of the power supply will also produce a large current shock to the projection bulb, the projection bulb will also be easily damaged. In order to avoid damage to these bulbs, we try not to switch the projector on and off too often, and remember that if you want to reboot the projector after turning it off, you have to be patient and wait for about 5 minutes.

2, the projection environment should not be reflective

Many people often mistakenly think that as long as the brightness of the lamp is high enough, the projection effect will be very clear and easy to distinguish; in fact, the projection effect is good or bad, in addition to the relationship with the brightness of the lamp, and the lamp working environment has a relationship with the work environment, working environment, the intensity of the light will affect the effect of the projection. So we must arrange a good working environment for projection, as far as possible to avoid the projection bulb work in too strong light conditions, which is due to too strong ambient light may make the bulb brightness effect becomes worse; so to get a better projection effect, we may wish to install curtains in the room in order to block the outdoor light; the room's walls, the floor should not be used to reflective materials, because these details will be Let the light bulb brightness to produce the effect of a higher level.

3. Ensure that the power supply is "identical"

In order to prevent the lamp from exploding or mismatching power, the projector is connected to a power supply with strict specifications. When connecting the projector to a power outlet, users should pay attention to the nominal value of the power supply voltage, the machine's ground and power polarity, and the grounding. This is due to the fact that when the projector is connected to a signal source (e.g., a PC) with a different power supply, there may be a high potential difference between the two zero lines. When the user plugs and unplugs the signal cable or other circuits with electricity, it will fire between the plug and socket, damaging the signal input circuit, which may not only prevent the bulb from working properly, but also damage the projector, and in serious cases, can cause fire accidents. Therefore, it is best to use the power cord that comes with the projector, and to ensure that the socket connected to the power cord is grounded reliably.

4. Switch the power on and off in the right order

Because the power supply of the projector is responsible for supplying power to the internal circuitry of the projector and the projector lamp, if you don't turn off the power in the right order, the lamp may be turned off along with the circuitry, and the fan inside the projector may stop working, so that the lamp, as well as the projector, may be turned off. The projector in the working process produces a large amount of heat can not be timely through the fan to exclude out, it is likely to lead to bulb explosion. Many users who have just begun to contact the projector, often very casually and frequently switch on and off the projector, in fact, the projector on its power to turn on and off is strictly regulated, otherwise it may damage the bulb or the projector. Usually, when we turn on the projector, we should first turn on the power, and then continue to press and hold the LAMP indicator in the projector control panel until the green light that appears does not blink. When you turn off the projector, you can't cut off the power directly, but you should press and hold the LAMP indicator until the green light doesn't flash and the projector cooling fan stops rotating, and then finally cut off the power. Therefore, the correct switching of the projector's power supply has a great impact on the life of the lamp as well as the life of the projector's internal accessories.

5, not more than four hours of work at a time

If the projector bulb is working for a long time, the imaging system inside the projector may emit a lot of heat, which will lead to a rapid increase in the temperature inside the projector, due to the high temperature of the projector bulb wall of the quartz in the high-temperature conditions will be generated by the phenomenon of loss of translucency, which appeared in the white spots, so a lot of loss of chastity at the blocking of light, so that the local area temperature is abnormally high. So that the local area temperature rises abnormally, which in turn causes the loss of chastity area to further expand, so that the brightness of the rapid decline, and is likely to lead to the explosion of the bulb. Therefore, we must pay attention to let the projector each time the duration of work can not exceed four hours.

In addition:

Projector light source lamp working time setting

In the case of a long time of continuous use, the projector light source lamp life of about 1500 hours, due to the use of different environments, the length of their service life will vary, and sometimes may be less than 1500 hours. Here, I will take the Mitsubishi x500u as an example to introduce how to "extend" the life of the projector light source lamp.

When the light source lamp has been used to about 1400 hours (bulb mode for standard), the projection screen will appear "LAMP" prompt, display time for one minute, which indicates the need to replace the lamp to the projector, such as not to replace the projector will automatically shut down. At this time, if the light source lamp work time to reset, it is not necessary to replace the bulb, you can continue to use. The specific operation method is as follows:

Plug in the power cord, turn on the power of the projector, press and hold down the power button and the left and right control arrow keys at the same time (Note: Be sure to operate on the control panel on the body of the projector, the operation of the remote control is invalid), to reset the working time of the light source lamp, be sure to confirm that the TEMP indicator lights up for about two seconds after the work of the light source lamp time can be reset. This way the projector can work normally again, and you can save another expense.
