Currently, Projector Industry is the most fiery Technologies DLP’s 3D show is not, nor is it a breakthrough 4K resolution 3LCD, but LED Light supply Technologies. Due to the fact of its little size, extended life, power saving has Environmental protection , Which undoubtedly is the standard source Projection Machines the most want to attain. LED also has a weakness, nevertheless, that the brightness has not reached the mainstream needs. Even following practically two years of development, LED light supply projector has entered the sensible stage, but the higher price and relatively low intensity, is nonetheless hindered their development constraints.
Present, the projector market place, the most fiery of the 3D DLP show technologies is not, nor is it a breakthrough 4K resolution 3LCD, but the LED light supply technologies. Simply because of its little size, lengthy life, power saving and atmosphere-friendly, and this is undoubtedly the most classic light projector trying to obtain. LED also has a weakness, however, that the brightness has not reached the mainstream requirements. Even following practically two years of development, LED light source projector has entered the practical stage, but the high cost and relatively low intensity, is nonetheless hindered their development constraints.
But in all the men and women are concerned about the new light source at the very same time, expectations had been offered this when disappeared after laser projection technologies, right now raised his head again. Especially in the 2008 Beijing Olympic Games, the Beijing Olympic Committee as the Branch to offer a exclusive laser show technologies a laser projector. By the Bureau of Beijing as the Chinese Academy of Sciences and Beijing Institute of Opto UME Huaxing International Studios have jointly launched the laser has been put into commercial operation theater. CTV in Division pioneered the laser PLPS-10000 lumen projector, even won a large screen sector method integration contractors, technique integrators, Case dual awards, and in July 2009, Beijing Municipal Science and Technology Commission and other departments were identified fourth independent revolutionary merchandise for Beijing. Laser projector with higher brightness, color reproduction and far more all-natural colour, long life and low energy consumption is for folks fascination. Some folks ask, the advent of laser projector, laser projection of the instances mean that really come out?
This, we can not give a clear answer. However, from the current penetration of laser projector, the laser projection of the times is far from coming.
Although, in 2008, the first in China, as the subjects created with independent intellectual house rights “really Star,” “Massive Dipper” series of laser items. Its small size, higher efficiency, higher stability and lengthy life benefits, is the only fully meet the present industrial applications of laser show patent merchandise. Even so, this does not cover laser projection technologies is still in the analysis and development stage of such a reality.
Manufacturing laser projector, at least two conditions: very first, to obtain 3 colors of laser followed by the require to be able to attain laser scanning point by point, but in each circumstances, there is not a small dilemma. The most critical constraint difficulty has not been proper from the solid-state green laser available. Green laser wavelength of about 540nm, red laser by way of a quartz oscillator according to sine wave to achieve frequency doubling, to get the green laser. Due to the fact of this approach is fairly higher temperature specifications on the atmosphere, and consequently the output is not stable sufficient, even though the green laser module is bigger and expensive.
Security is also a factor restricting the development of 1. Laser projector has been characterized is the massive luminous flux, energy to 20W the projector, the luminous flux reached 5000lum, busybody brings take a lens if it is feasible to burn one thing to a specific distance. To know that a 150mw laser at 1 m can be simply burned away we generally use Plastic Film bag, the cutting of some industrial Machine tool Laser power is also significantly far better than this. As a result, in open spaces, the dilemma worse.
The price is an additional obstacle, which is restricting the maximum laser projector universal one of the aspects. Low yield LCOS technology improvement used to be the elements constraining, but now it has become a constraining factor in the development of laser projectors. Academician Wang Zhanguo pointed out, do laser show market, higher efforts to enhance the yield is the important. Though laser projection has now been some product launches, but the actual production of such products to the present yield is beneath normal, which needs the state and enterprises invested heavily to develop. Only solution in the production price, and price is attainable down.
