As we all know, the traditional DLP projection equipment is the most popular one is the UHP light source. The average life of 6000 hours leads to the user's use cost can not be reduced, and the LED light source is 10 times longer than the UHP life, which is a good solution. This problem. But is the current LED light source perfect? ​​What should you pay attention to in use?
First, the choice of brightness and color gamut
Although the LED light source has already reached the K-level lumen brightness in the traditional outdoor LED display, it still generally stays in the range of 600-800 lumens (highlight working mode) in the application of DLP, so for the use environment Ambient light is subject to more stringent controls to minimize customer sensitivity to insufficient brightness of the LED source.
At the same time, due to the wide color gamut of the LED light source (see Figure 1), we have the opportunity to apply in more complex environments. If the ambient light source is a normal cool white or incandescent lamp, it is recommended to adjust the color temperature to a range of 7500-9300K, which makes the human eye feel brighter and more vivid.
Second, heat dissipation
Due to the spectral characteristics of the LED light source, the heat generated by the light source portion is higher than the UHP at the same brightness (see Figure 2). Therefore, it has higher requirements for the heat dissipation design requirements of the entire projection display unit and the control of the ambient temperature. At present, the mainstream heat dissipation methods are mainly air-cooled and water-cooled. It should be said that each has its own advantages and disadvantages. The air-cooled type is more traditional and mature, and the water-cooling heat dissipation efficiency is slightly higher than that of the air-cooled type, but the design difficulty is high, and the reliability of long-term use needs to be tested.
Third, maintenance
Due to the short life span and the rapid attenuation of brightness, the traditional UHP light source requires a higher frequency of regular debugging after being put into use, so that the brightness and color uniformity can be maintained at a certain level. The high lifetime and low attenuation characteristics of the LED light source improve this situation very well, and because there is no color wheel, there is no need to consider the effect of long-running dust on the color output of the optical machine (see Figure 3). This greatly saves the manpower required for maintenance.
Fourth, the cost of use
Since the life of the LED light source has reached 60000h and there is no color wheel, it is theoretically in the device.
There is no need to consider the expenditure of consumables within the normal life cycle.
In summary, the LED light source projector has taken a big step in terms of the use effect and maintenance cost compared to UHP. As long as the breakthrough in the brightness of the light source is achieved as soon as possible, it can be predicted that it will dominate the entire high-end large-screen splicing market within a certain period of time.
