At present, LED light source is used in the DLP camp. The highest luminous flux output has exceeded 1200 ampere lumens (ANSILm, American projector brightness standard). Although this indicator is only a relatively low brightness level of mainstream projectors, it is already very remarkable. In the 3LCD camp, it is a step behind, and has not broken through 1000 ampere lumens (almost at around 400 amps, the lumens have been going on, but this brightness is enough for home theater use, perhaps this is also the real reason for "always on"). However, the contribution to the lightweight, cost-effective, long-life, low-attenuation, and low-depreciation of optical machines is unquestionable.
For domestic single LCD projectors, it is clear that there are not many manufacturers who have been paying attention to and investing in LEDs, because the attitude of the private sector on intellectual property rights is still at a level that needs to be strengthened. LED is used for single LCD projectors, and it is not an easy task (except for the cottage). As a professional manufacturer and promotion manufacturer of domestic projectors, there are too many factors to consider, such as the supply of raw materials, optimization of cost performance, and stability control. Long-term compatibility during the period, etc., when these factors are close to reasonable or basically reasonable and in line with market demand, LED light source projectors will be mass-produced or small-volume production and market promotion.
The most basic advantages and features of LED light source projector
The practical value refers not to the concept of “using LEDâ€, but the projector's luminous flux output should meet the most basic requirements of KTV and the establishment of home theater. According to the authoritative results of scientific statistics, the most basic luminous flux indicators are needed. 100 ampere lumens around. Now, it can fully meet the needs of the market and users.
As we all know, energy conservation and environmental protection has become one of the most concerned topics in society. For the end user, if the LED projector is 40W power consumption, and the traditional metal halide lamp source is 200W power consumption, one projector can save about 160W power, which seems to have no practical meaning for any family and users. ,why? If the projector has a service life of 20,000 hours, saving 0.16 kWh per hour, it will only save 3200 kWh, equivalent to RMB 2240 (according to 0.7 yuan/kWh), but buying such an LED light source projector may be similar. It is also necessary to spend an additional 1,000 yuan, which will only save 1240 yuan in electricity costs, but 6 hours a day, 20,000 hours need to use more than 9 years, can only save 130 yuan a year, save 11 yuan in January, equivalent to more I smoked a pack of cigarettes, so there is no value, and there is absolutely no attraction for customers who care about the immediate interests.
