At present, the solid-state light source in the field of projectors is basically the world of lasers and LEDs . The current cost of lasers is somewhat high. Although there are also preferential price schemes, the color performance is not ideal. The color of the LED light source is no problem, but the brightness has always been a short board. Even if there are many new products on the market, there are still few products with more than 1000 lumens. So LED light source really has no hope of brightness breakthrough? the answer is negative.
The technical principle of LED light source projector
Since last year, Philips has been demonstrating high-density HLD (High Lumen Density) LED projection light source technology. HLD LED projectors will be able to achieve a large image projection under the general light source under the circumstance of the general light source. After adopting HLD LED technology , it can increase the projection brightness and color reproducibility by three times, in view of the current LED brightness. Basically, the effect of 500 ANSI lumens can be achieved. If it can achieve 3 times the effect, the level of 1500 ANSI lumens is basically the brightness of the 3000 lumens horizontal bulb projector.
The brightness of ordinary LED light source is not enough
In the past few years, various solid-state light source technologies have flourished in the market, but the market share of projectors with brightness above 1000 lumens accounted for less than 5% of total sales. A big problem with this is that brightness does not meet people's needs. The emergence of Philips' HLD LED light source technology has given new hope to the breakthrough of brightness. If this technology is really reliable, then the LED projector will set off a new wave.
HLD LED light source may ignite new craze
The author also asked some people in the industry about this issue. They also said that there will be projectors for HLD light sources in the future. At the end of 2016, this new product may meet with you. The author also discussed with the professionals about the cost. They said that the cost of the HLD source is higher than that of the laser source of the same brightness, but the color advantage of the HLD source is also obvious. After all, the laser source is always bright. Not allowed."
From the current state of view, the technical problem of HLD light source should not be very large, and the future cost may become a key issue affecting the popularity of this technology. However, the LED light source is actually very expensive at the beginning, and now it is relatively close to the people. The author believes that the cost problem will be solved in the end, but it will take more time.
The lightning surge arrester is designed for trouble-free power distribution. Polymer surge arrester protect transformers, switchgear and other equipment from switching and lightning surges. Polymer specis lighting arrester meet or exceed all requirements of the latest IEC standards and can be selected to match the range of pollution and energy requirements. Polymer lightning arrester should be installed in parallel between the line and ground to the transformer or cable termination or other object to be protected. Compared with arresters made of ceramic materials, polymer lightning protection devices can be widely used in medium and high voltage power grids in coastal and heavily polluted areas.
Features
1. Small volume and light weight2. Protecting the shell body from breaking up when the pressure from thermal shock released
3. Easy to tell if the application still work due to its carbonization when shell body flashs over
4. Better performance in high contamination areas
5. Good sealing performance
