Since the first dust-free light machine developed and produced in 2011, Chuang Rong has been providing its own solutions to solve the problems of heat dissipation and dust prevention. At first, Chuang Rong started with the traditional projector and sealed the main body of the optical machine, but the contradiction between brightness and heat dissipation could not be resolved. The closure of the internal space of the optical machine also means that it is more difficult to dissipate heat. The light source directly shines on the display screen, often burning the screen in less than 20 minutes; If the brightness of the light source is reduced, the problem of heat dissipation will be solved. However, the imaging brightness is too low, and the projection effect is unrecognizable, which does not meet the general projection requirements.

After continuous testing by the research team, the first generation of dust-free light machine was successfully developed by setting insulating glass, reducing the brightness of light source and other methods. With the advantages of high quality and low after-sales compared with other projectors in the market, the projectors equipped with dust-free light machines have received great success at home and abroad. Although the first generation of dust-free light machine still has defects such as low brightness and high noise, this has strengthened the Chuang Rong team's belief in technological innovation in the industry, The production of projectors and optical machines strictly guarantees the quality, reduces after-sales problems, and is responsible for each projector, which also lays the foundation for the subsequent successful development of fully enclosed dust-free optical machines.

In 2018, the Chuang Rong mini fully enclosed dust-free light machine was officially launched. Compared with the previous direct light design, this new fully enclosed dust-free light machine uses a double refraction design, which gives a unique answer to the industry's long-standing heat dissipation problem, and also shows the industry that the fully enclosed light machine is a strong trend in the future development of the industry. The internal structure of the optical machine has a complete imaging system and cooling system, which makes it possible to sell the optical machine as a commodity. Any customer who wants to enter the projector industry no longer needs to have a perfect optical R&D team, but only needs to provide the desired solution. Chuang Rong will provide a one-stop customized solution.

From the perspective of product quality, at present, Chuang Rong fully enclosed dust-free light machine has developed a highlighted version. Compared with the previous commercial projectors, the brightness gap has been further narrowed. The newly developed D9 and D16 light machines are completely suitable for home projection. They are smaller and support more customized schemes. The brightness is no less than that of horizontal light machines.

The design of the fully enclosed dust-free light machine has completely changed the awkward positioning of the home projector, greatly extended its service life, and avoided after-sales problems such as blurring of the lens due to gray dots, overheating and burning of the display screen. Based on the technical innovation of the fully sealed dust-free light machine, the household projector industry, which was originally dismissed as a "toy", has been revitalized and ignited the entire projector market.
