In terms of durability, HLD also has the advantage of long life. The current life of HLD light sources that have been introduced into the laser pointer market is 20,000 hours, which is almost the same as the life of lasers. Therefore, in this perspective, laser and HLD are hard to distinguish between victory and defeat, and both have lower maintenance costs. The brightness and volume are the disadvantages of HLD. In fact, in the entire projection industry, if it comes to brightness, no one can match the laser. Although the brightness of HLD has been significantly improved compared with the past, compared with laser, this progress can be said to be negligible.
In the high-end field of more than 8000 lumens, HLD has not yet been involved in capital. In addition, with the increase in brightness, the volume of HLD projectors will also become larger, because the problems directly caused by the increase in brightness are the increase in lamp power and heat dissipation. Big projector volume to achieve. But whether it is a home user or a business education user, the large size means that it is more laborious to move and install, which is also a disadvantage of HLD.
Compared with the monochromatic laser + fluorescent color wheel scheme, HLD has a wider color gamut and better color performance. Compared with the two-color laser scheme, the cost of HLD is much lower, which is a major advantage of HLD compared to laser. But in terms of brightness, body volume, etc., HLD is not yet comparable to lasers. Therefore, the author believes that the overall performance of HLD is slightly inferior to laser pointers. Who is more bullish on market feedback? Regarding the two new light sources, laser and HLD, how do the industry giants think about it? We can see some clues from the product side.
