The shortcomings of LED light sources in brightness are destined to be unable to compete with lasers. In fact, in addition to BenQ, Hitachi has always been preparing to use HLD technology on educational projectors. Hitachi has also demonstrated this technology once, and prototypes have also appeared on the scene. But until the end of the year, Hitachi did not take much action. Therefore, it can be seen that the current development of HLD technology is not very fast.
The current theory of HLD light source is to achieve the level of 3000 lumens, and it is still very difficult to continue to improve. Because the problem of LED green luminous efficiency is not easy to solve. The general brightness of the laser pointer light source has reached more than 6000 lumens (new product of engineering projector), so it is obvious that HLD technology cannot compete for the engineering market in terms of brightness. At present, the color of HLD technology is better, and there is no color wheel at the same time, which can prevent rainbow phenomenon. Its future development prospects are the home and education markets. But at present, its cost control is not very good, and there will be no more sudden outbreaks in the short term.
Finally, let’s talk about the traditional projector bulbs. Due to the emergence of various new laser pointer light sources, the traditional bulbs have a feeling of “grandmother doesn’t love grandpa or grandpa” in recent years. Today, the price of various raw materials is rising. The purchase price of light bulbs has also been reduced. This is also the result of fierce market competition. In fact, the current light bulb manufacturers, including Osram and Philips, etc., have put their research and development efforts on new light sources, and there have been few technological changes in traditional light bulbs.
Although some light bulbs now have Eco mode to extend their lifespan, due to this method of reducing brightness and extending their lifespan, there is not much market prospect under the influence of new light sources. Relying on the price advantage, the traditional business and education market, and the entry-level home entertainment market, the application of light bulbs is still very rich. The future bulb light source market is basically locked in these areas and will gradually shrink. Maybe one day the bulb projector will disappear in the long river of history like a plasma TV.
The current development prospects of green laser pointer light sources are the best. This is the basic change in the light source market. The sudden emergence of lasers. HLD technology is still lonely. The market potential does not seem to be sufficient. Traditional bulb light sources can only fight price wars in the entry market. In the future, with the development of new light sources, its market The atmosphere will become smaller and smaller or even disappear. Other light sources, such as LED+laser hybrid modes, are currently only being done by Casio, and the market’s sound is very small and cannot affect the big picture. Finally, if we look at the whole world, we will find that the development of new light source technology is the fastest in China, and the changes in the Chinese market are the future of the European and American markets. This is an unprecedented situation.
