For projector users, it is very important to choose the projector bulb according to the projector used, the environment in which the projector is used and the frequency of use. However, not every projector user knows these choices. skill. Some users think that the higher the brightness of the light bulb, the better. Some people think that it is better to choose the right type. Even some users think that the more expensive the light bulb, the better, or the cheaper the more affordable, in fact, this kind of idea is one-sided. Even wrong. In fact, we must choose the type of projector to use, and then choose the projector bulb that suits your needs according to your needs and the environment. ![]()
Select projector bulbs from type and characteristics
At present, the projector bulbs on the market mainly include two types of ultra-high pressure mercury bulbs and metal halogen bulbs. The UHE, UHP and UMPRD bulbs we usually see are divided into different brands. For example, UHE is the projector lamp model of Eposn, UHP is the projector bulb brand of Philips (PHILIPS), UMPRD/UMVRD/NSH It is the bulb model of Uchiha, Japan, SHP is the bulb model of Japan Phoenix, SHL is the singular bulb model of the United States, and the VIP is the bulb model of Osram of Germany. Among these models, some are metal halide bulbs, named after the bulbs are filled with metal halides, and more are ultra-high pressure mercury bulbs. As the name implies, the bulbs are filled with high-pressure mercury. Among the many types of bulbs, UHE bulbs, UHP bulbs and metal halide bulbs are the most used. UHE and UHP are ultra-high pressure mercury bulbs.
UHE bulbs and UHP bulbs with ultra-high pressure mercury filling technology are often referred to as cold light bulbs because of their low power consumption and low heat generation. The current mainstream bulb type is cold light bulb. The advantage of the cold light source bulb is very obvious, because its power consumption is low, the heat is small, and the temperature rise of the projector is relatively low, so it is suitable for the projector to work for a long time, and the performance curve of the bulb is smooth and long. The use of brightness reduction is not as obvious.
UHE bulbs are widely used in mid-range projectors. They have the advantages of moderate price, rich variety, long life, generally more than 3,000 hours, and almost no attenuation before 2000 hours of use. UHP bulbs are also a mainstream projector bulb type. They are also cold light source type bulbs. They are used longer than UHE and can be used normally for 4000 hours to 5000 hours, and the longest is even nominally 12,000 hours. The brightness attenuation is very small, but its patented technology is monopolized by Philips, so the price is relatively high, generally more than 3,000 yuan, generally used in high-end projectors. One feature of UHP bulbs is that when depleted, the bulb is extinguished immediately.
Metal halide lamps are not cold light sources, they generate warm light, require more power to produce the same brightness as cold light bulbs, and have a shorter life span and a greater brightness decay. Generally, after 1000 hours, the brightness is probably only new bulbs. Half of it. And it generates a large amount of heat, which makes the temperature of the whole projector higher, and the heat dissipation system of the projector is also relatively high, so it is not suitable for long-time projection use. Unlike UHP lamps, metal halide lamp failure is extinguished instantly, but gradually extinguished.
In addition, it is important to note that the bulbs of different projectors are generally not universal, so be sure to carefully check which type of bulbs the projector uses when purchasing. Although buying a light bulb can't just look at the type, but it doesn't work without looking at the type.![]()
Select projector bulb from performance
The light bulb is one of the important parts of the projector, so its performance directly determines the effect of the projection. Different types of bulbs have different performances, but performance is not entirely determined by type. The performance of a projector bulb depends on power, brightness, and useful life. Secondly, the brand of the bulb is also the reference object of our purchase, because to a certain extent, the brand of the bulb represents the overall performance of the bulb, everyone knows that brand-name products are better than unknown products. Select a projection bulb from the environment of use
The projection principle of the projector is to use the light bulb in the projector to generate strong light to project the signal onto a large screen with a long distance. The projection effect is not only related to the performance of the projector, but also the environment in which the projector is used. Very big relationship. Obviously, the effect of projection in a high-brightness environment is much worse than in a darker environment. The higher the brightness of the environment, the farther the projection distance, and the larger the projection screen, the higher the brightness. On the contrary, if the ambient brightness is dark, the projection distance is relatively close, and the projection screen is small, only the lower brightness is required. Just fine. The brightness of the projector is determined by the light bulb. It can be said that in the projector, the light bulb dominates everything. A high-end projector, if the brightness of the bulb is not enough, can not get a good projection effect.
Therefore, when selecting a light bulb, it must be purchased according to the environment in which the projector is used. For example, the use in a small conference room, the space is small, the projection screen is not too large, the brightness requirements in this environment will not be very high, generally can be used normally around 1000 lumens, ordinary metal halogen bulbs can be This brightness is achieved. If it is used in a relatively large conference hall, the projection distance is generally far, and the projection screen is relatively large. Such users also require higher brightness and contrast when purchasing the bulb, usually requiring 2000 lumens or more. This kind of user can only choose UHE or UHP of cold light source type, UMRRD, SAP, etc. when purchasing a light bulb. If it is a home user, mainly for watching TV and movies, the requirements for clarity and dynamic effects are relatively high, so the brightness requirements of the projector bulb are relatively high, even higher than the brightness of the large conference hall, so it is high. The bright light source bulb of brightness is also the best for home users.![]()
Select projector bulbs from cost and frequency of use
Different bulb prices are different. Metal halide bulbs are cheaper than normal. Generally, as long as 1000 yuan to 2,000 yuan, UHE bulbs are generally between 2,000 yuan and 4,000 yuan. UHP bulbs generally have a long service life of 4,000. Above yuan, some even above 8,000 yuan. The cost of a light bulb is about 30% of the projector, so which type of light bulb to buy depends on the frequency of use of the projector, so that it does not waste.
If the frequency of use is not high and the use time is not long, you can choose a metal halogen bulb with a short life and low price. Its 2000-hour service life is enough for users who are not using it for a long time. For large and medium-sized enterprises and home users, the use of more frequent, and long-term use, it is best to use UHE, UHP cold light bulbs with long-lived brightness reduction, such bulbs not only ensure that the projector works for a long time, and It also provides High brightness and contrast to meet the user's need for projection on large screens and long distances. If the user who uses the projector for a long time also chooses a metal halogen bulb, although the price of the bulb is relatively cheap, the cost of frequency replacement is also high, so it is recommended that users who use the projector for a long time choose a cold light source with a long life. light bulb. In addition, it should be noted that when buying a light bulb, do not choose a brand-name inferior product because it is cheap, because the light bulb is working in a high temperature and high pressure environment. If the quality is not good, the bulb may burst and explode.
Precautions
The projector bulb has always been a delicate feeling. After all, the price is not low. If it is used improperly, it will cause the bulb to burst, explode and even damage the entire projector. First of all, for a projector using a metal halide bulb, it is strictly prohibited to move it when it is turned on. Because the halogen bulb is in the state of lighting, the temperature is thousands of degrees, the filament is in a semi-molten state, and the filament is likely to cause the filament to be moved. Disconnected, the bulb bursts. Secondly, the projector should be switched on and off at least for about 5 minutes. Inappropriate frequent switching may cause the projector to overheat and cause the bulb to explode. Also, when the projector is turned off, it must wait for the cooling fan to stop running, and then turn off the power switch. Otherwise, the lamp will explode because the projector cannot dissipate heat in time.![]()
The development direction of the projector bulb
Recently, there has been a rookie in the family of projector bulbs - the neon light. Xenon lamp is a kind of light source that uses the arc generated by the discharge between positive and negative electrodes. Due to its high technical content and high price, it is currently only used in high-end projectors. Since the spectrum of the xenon lamp is closest to natural light, it can provide superior color than other light sources. Compared with UHP bulbs, xenon lamps have the advantage of being able to switch at any time, and can be turned on again immediately after the xenon lamp is turned off, which was not possible with other projector bulbs. Xenon lamps are a promising source of light, and as technology advances and matures, it will be universally applied to a variety of projectors. In addition, the cost of replacing the projection bulb can now be saved by replacing the bulb wick. Projector bulbs will move toward more advanced technology, higher brightness, longer life and lower cost.
Before purchasing a projector, it is a wise choice to learn to purchase a light bulb. This will save the projector's budget for future use and save unnecessary expenses.
