High Brightness Version of Laser Pointer Light Source

The entire projection industry has been updated frequently in recent years, especially the maturity of the laser pointer technology has made the quality of projection products have a qualitative leap, and the sales of laser pointer projections in education are also rising. However, we have noticed that a light source called HLD is favored by many manufacturers. Many new types of educational projectors released in recent times have adopted such light sources. So why is this? Today we will take you to know.

What is HLD? In fact, literally nine can clearly understand that HLD is called High Lumen Density, which is a high-brightness version of the LED light source. HLD not only inherits the excellent color and service life of LED, but also solves the problem of LED brightness bottleneck to some extent.

From a technical point of view, it is to improve the overall brightness of the LED by improving the luminous efficiency of the green part of the LED. The brightness of the HLD can be more than 3000 lumens, and the color performance of the LED is improved compared with the safety. The aspect is better than the laser source, so HLD has become the main competitor of the hot laser source.

HLD and laser pointer, if you take a single comparison, can’t explain what the problem is. Take color as an example. We have mentioned it many times in previous articles. Theoretically, three-color lasers have a very wide color gamut, and the actual color performance is the best among known light sources.

But what we should pay attention to is the three-color laser source we are talking about. This kind of light source is good or expensive. Most products in the current market still use a combination of monochromatic laser and phosphor, and some of them are the latest ones. The two-color laser, the high price, can only be used in the middle and high-end products. In the short term, it is hoped that the three-color laser will be widely used in the short-term.

Therefore, if you want to compare the combination of monochromatic laser and phosphor with HLD, the monochromatic laser plus phosphor is mainly blue laser, that is, the color in the projection picture is derived from blue, which is easy. The color cast occurs, the color accuracy is not satisfactory, and the HLD color performance is much better.

The field of LED is very wide, especially in the unshakable core position of the lighting industry. In the case of continuous research and development breakthroughs in multiple industries, the laser pointer projection market is backed up, so that it can be fully technically optimized, and the field involved in lasers will be relatively simple. some. Therefore, from an industrial perspective, HLD has more development potential.

From the market point of view, HLD is “debuted” three years later than the laser, and it has gradually appeared in the market this year, but it has to be acknowledged and because of the extremely wide application field of LED light source and the huge industrial scale, it is destined to be more than laser. Technology has better development prospects and cost advantages.

As far as the education industry is concerned, users are not very sensitive to the price of the whole machine, but care about actual safety and post-maintenance costs. Compared with laser, HLD is better in color, the price is relatively cheaper, the overall quality is stronger, and it conforms to the green health concept, which is more suitable for the needs of the education market. The various characteristics of HLD light source just meet the needs of the education industry, and can solve the pain point very well. Therefore, it is understandable that major manufacturers will re-inject on the HLD education projection. The HLD light source education model will gradually become the main light source of the education market. .

In the first half of 2018, manufacturers have already pre-empted the HLD education market. Sharp, Panasonic, NEC and other brands have successively launched new HLD education projectors. After that, it is believed that more manufacturers will follow up, and the laser and HLD are parallel. The situation will continue for a long time.
