LED is believed to be familiar to everyone. It has many advantages such as long life and low energy consumption, and is now widely used in laser pointer lighting business in various industries. But in the projection industry, LED light source has a fatal disadvantage, that is, the brightness is too low. HLD uses a new light-emitting chip and packaging technology, which improves the overall brightness of the light source by improving the luminous efficiency of the green part of the LED. At present, the brightness of HLD can reach 1000-5000 lumens, which can already meet the needs of most industries.
At present, many brands on the market have launched HLD projection products. At present, many Chinese and foreign brands on the market, including BenQ and NEC, have launched projection products using HLD light sources. These products are more used in business education markets. In addition, according to the information obtained by the author, Panasonic will also launch HLD ultra-short focus projection for the education market in the near future, and Sharp also has a layout in the field of HLD.
Looking at the pros and cons of HLD today? Compared with lasers, HLD light sources do not require special safety protection and speckle processing. This helps reduce the complexity of the product, which is more conducive to solving costs. Therefore, compared with monochrome laser pointers in the same lumen segment, although HLD products are currently more expensive, there is still room for price reduction in the future.
