Since the birth of projector, its biggest bottleneck in image quality is the light source. Halogen lamp, led and other traditional projector light source's initial brightness is significantly weaker than LCD TV, and will be further reduced in use, so it is difficult to completely replace LCD TV to become the mainstream choice of home screen. In this context, the "black technology" such as the new HLD light source plays a "guiding light" role for projectors

On August 16, 2017, inask Yingshi held a new product release conference with the theme of "light future, color boundless" in Shanghai. The two new models of Yingshi HLD new light source projectors adopted the HLD light source pushed by Philips. Compared with the traditional projectors, they made significant breakthroughs in the performance indicators of brightness, color and life, which aroused the strong interest of agents. Despite the hot weather, such a large meeting was held The conference room was almost full.

Mr. Zhu Zhiheng, general manager of Shanghai Lijing, Ms. Li Li, sales manager of Philips in China, Mr. Wang Zhijie, sales director of Philips Greater China and South Korea, and Mr. Liu Yuan, sales director of weishijiajie business equipment division, attended the scene and made wonderful speeches. Mr. Zhu Zhiheng, general manager of Shanghai Lijing, said in his speech that as the supplier of procurement agreement between Shanghai municipal government and central government, as well as the general representative of several international famous brands, Lijing has been committed to providing users with the best projector products, multimedia intelligent home theater, multimedia conference room and other solutions.

In recent years, some domestic projector manufacturers, with the blessing of Internet thinking, have brought great challenges, which have made the industry feel great pressure, but also have new inspiration. In particular, the emergence and maturity of new light source technology have brought hope to the market, so that Lijing, who has always attached great importance to quality service, is full of enthusiasm again and continues to strive for the vigorous growth of the projector market.

Ms. Li Li, sales manager of Philips China, elaborated the essence of HLD light source in the press conference speech. HLD is the abbreviation of color spark high lumen density LED. The biggest feature is that its brightness can exceed three times of the traditional LED projector light source, and the color display ability will also be greatly improved.

The development of HLD technology is to solve a series of bottleneck problems faced by LED projectors. In the past, in order to improve the output brightness of LED projectors, either the quantum efficiency of LEDs or the luminous area of LEDs would be increased, but the light conversion efficiency would be reduced. The HLD solution of Philips is to use the light of multiple blue LED light-emitting units into the light guide tube with fluorescence, and then output the light after efficient integration. It can not only greatly improve the overall brightness, but also convert the blue light into green light or red light, especially to enhance the weak green light short board in the traditional light source, so as to enhance the overall color brightness!

This compact HLD chip developed by Philips is not simple in performance. Compared with traditional halogen lamp and LED light source, its brightness has been greatly improved, and compared with laser TV, it has a considerable advantage in color accuracy. From a technical point of view, HLD light source does not need the special safety protection, beam expansion and speckle processing of laser light source, which helps to reduce the complexity of product design, and greatly reduces the cost. It also provides a new solution for the majority of projector manufacturers.

Mr. Liu Yuan, sales director of weishijiajie business equipment division, said in the speech that HLD light source is RGB three-color light source, which is significantly different from monochromatic laser fluorescence technology which must use color wheel technology at present. HLD light source has six advantages, such as accurate color, high brightness, long-term durability, safety and reliability, easy maintenance and low cost. Therefore, Yingshi introduced HLD light source in this year's new products. This conference officially released the reflective ultra short focus series covering the education and home entertainment market, as well as the engineering projection series for the high-end commercial market.

In addition to the advanced light source, the lens performance of the reflective ultra short focus projector released this time is also unique, with a unique 1.06 times optical zoom, and a certain horizontal and vertical correction ability, which is more conducive to the flexible installation of hanging projection. The projection ratio of the engineering projector is also very good. The distance of 2.2-3.5 meters can project a large picture of 100 inches, which can better adapt to small and medium-sized conference rooms.

There is no doubt that with the addition of new light source, Yingshi's new projector has made a significant progress in image quality performance. After the industry market, the next stage of the expansion of the consumer market will be able to further enhance the overall value of its brand and bring more practical new home theater solutions to the majority of consumers.
