At present, the problems faced by HLD are volume and energy consumption. It is precisely these two points that are more concerned by home users. This may be why the current green laser pointer has not achieved much in the domestic field. But as mentioned before, LEDs have penetrated into various fields, and the development speed is obviously faster. Perhaps in the future, the market below 6000 lumens will be occupied by HLD, and the field of engineering machines above 6000 lumens will be the world of lasers.
Editor’s point of view: With the development of the market, it is sooner or later that traditional light sources will be eliminated, and the future will be the world of new light sources. In the field of new light sources, lasers have clearly occupied a leading position before. But a big family is not good for the whole development, because without a sense of crisis, there is no motivation to move forward. The author believes that the emergence of HLD light sources has formed a competitive relationship with lasers and is expected to challenge the industry’s dominance of lasers. The progress of the industry is inseparable from competition. In my opinion, the head-to-head confrontation between HLD and green laser pointer will promote the rapid development of the entire projection market.
The HLD light source can well solve the daily pain points of education users, so the HLD projectors on the market are more targeted at the education industry. First, because it is aimed at minors, the education market places the highest value on eye protection. This is exactly the advantage of HLD, because HLD projectors have less blue light, so they are more eye-protecting.
