What are the advantages and disadvantages of laser projection, LED projection and general projection?
LED light projector with high light source life and lightweight, portable body volume has been high hopes. Launched in the core technology vendors TI HD micro cast chip, projector manufacturers launched 500 lumens bright high-definition LED light projector in the near future, with the traditional source of entertainment and entry-level business projector become rivals, and quickly occupied the individual market. In the final analysis, LED light source has the following main advantages, so it is touted by manufacturers and consumers.
First, long life, which is also one of the most important advantages for many consumers.Second, pure color, high color saturation.Third, moisture-proof, anti vibration.
A laser is an electric light source that uses excited particles to emit light under stimulated radiation. The laser light source is completely different from the high-pressure mercury lamp and the LED light source. First of all, the color of the laser is very pure, its monochromatic than ordinary light source more than 10 times higher than the light. Second, the laser source has excellent directionality, and the divergence of the beam is very small.In addition, the laser can achieve high brightness, only by increasing the number of lasers, can easily be a luminous flux of laser projector single reached 10000-50000 LM, and the service life of the light source can still reach 10000-20000 hours or more, not only can achieve higher brightness in the micro projector, is applied in engineering Theater products in the realization of high brightness, but also can prolong the service life.The LED light source lacks luminous efficiency per unit area in the presence of a fatal defect. As we all know, the size of the mobile phone LED light source projector brightness only 10 lumens, ultra portable projector 1 kilograms, brightness is only 500 lumens, to further enhance the brightness, also can make the body bigger and heavier.Compared to the traditional light source brightness projection machine easily 2-3 kilolumen, LED light projector is also difficult to achieve. As a result, the LED light projector is currently only suitable for personal and portable business users.
