The lcd projector is the product of the combination of liquid crystal display technology and projection technology. It uses the electro-optic effect of liquid crystal to control the transmittance and reflectivity of the liquid crystal unit through the circuit, thereby producing different gray levels and as many as 1670 million colors. Beautiful image. The main imaging device of LCD projector is liquid crystal panel. Led projector, generally refers to the light source of the projector is LED light source, the brightness is not high, within 500 lumens. The difference between dlp and led, most of them are in Projection field to distinguish. lcd home projector,led lcd home projector,best home lcd projector,lcd home theatre projectors,best lcd home theater projector Shenzhen Happybate Trading Co.,LTD , https://www.happybateprojector.com
LED indoor lighting status:
With the improvement of people's awareness of energy conservation and environmental protection, and the increasing emphasis on the new energy industry, the LED industry with environmental protection and energy saving features has made great progress in China in just a few years. In particular, in recent years, China has launched green lighting engineering and semiconductor lighting engineering, and has supported semiconductor lighting technology in the fields of ten key energy-saving projects, high-tech industrialization demonstration projects, enterprise technology upgrades and structural adjustment projects, and 863 new materials. The R&D and industrialization projects have made the Chinese LED industry a great achievement in the traditional fields such as backlighting and outdoor lighting, and also achieved a good start in the indoor lighting market. Some Chinese lighting companies have begun to explore the development of LED indoor lighting industry.
LED indoor lighting development trend:
During the day, the building shapes the space of light. At night, light limits the space of the building. If architecture is the carrier of space, then light is its life. Without light, space loses its meaning. Different lights produce different feelings. Reasonable light can make people feel the space atmosphere and enjoy the joy brought by light. On the contrary, it will make people feel depressed and unhappy. Indoor lighting is one of the most exposed lighting methods. Its design directly affects people's daily life and work, and its importance is self-evident. Under the efforts of the industry, indoor lighting is developing in an increasingly healthy and orderly direction. The mainstream development trends are as follows: 1. Energy saving; 2. Functional diversification (1) High color rendering; (2) Intelligent; (3) ) flexible; 3. thin and light; 4. environmental protection.
How should LED indoor lighting develop:
First, the rural surrounding city
The development of LED indoor lighting should follow the road of rural encircling the city. Ren Yuanhui, honorary director of the Interior Lighting Committee of the China Illuminating Society, said.
Why do you say this? Ren Yuanhui analyzed it for the following reasons: First, from the perspective of the application site, in view of the fact that LEDs are not competitive at present in indoor places that emphasize functional lighting, LEDs should be used for indoor lighting. Conquer some places that do not emphasize functional lighting, such as corridors, stairwells, lobbies, etc., and then develop into other indoor areas. Second, from the perspective of energy consumption, LEDs can replace the most energy-consuming incandescent lamps, replace halogen lamps, and finally strive to gradually replace compact fluorescent lamps. Indoors do not emphasize the field of functional lighting and high-energy lighting, just like rural areas, is the weakest piece of indoor lighting, first to overcome them. Step by step, and finally conquer the city of indoor lighting.
Second, the sand can be a tower
Stairs and walkways in residential or similar places are equipped with energy-saving self-extinguishing switches. Almost all incandescent lamps are used. It is most suitable to replace with LEDs. The energy-saving effect is good. Although it is only a small lamp, the number is large, and the country estimates that it is over 100 million. Its energy-saving benefits are considerable, and the economic benefits of enterprises are remarkable.
Third, do more than do more
The range of indoor lighting is wide, with school lighting, office lighting, shopping mall lighting, hotel lighting, home lighting and so on. Is it suitable for LED lighting in all indoor situations? Let's hear what the experts say. (Ren Yuanhui: Honorary Director of the Indoor Lighting Professional Committee of the China Illuminating Society, Zhao Jianping: Associate Dean of the Building Environment and Energy Conservation Institute of the China Academy of Building Research)
SCHOOL:
Ren Yuanhui: General lighting in the classroom is not applicable.
Zhao Jianping: Use with caution!
office:
Ren Yuanhui: General lighting in the office is not applicable.
Zhao Jianping: The choice between energy saving and vision protection.
the mall:
Ren Yuanhui: General lighting in shopping malls is not applicable, and the cylinders and spotlights that are used for key lighting in shopping malls are suitable.
Hotel:
Ren Yuanhui: Room headlights with dimming, bedside reading lights, night lights, wardrobe lights, bar lamps, door lights, entrance aisle lights, and bathroom bath lights are available. For crystal glass chandeliers, incandescent lamps can be used to produce colorful, compact fluorescent lamps are not allowed, and LEDs can be used for research applications.
Home:
Ren Yuanhui: Toilets, kitchens and other places can be applied.
Fourth, avoiding shortcomings and growing up
What are the problems with LED lighting in indoor lighting? First, the light is difficult to spread evenly; Second, the problem of glare; Third, the problem of color rendering. When developing indoor LED lamps, is it just a matter of avoiding these problems? In fact, the development of indoor LED lamps, while avoiding its shortcomings, must carry forward its strengths.
What indoor LED luminaires can be developed to take advantage of LEDs? Spotlights and downlights. This is because LEDs are directional and can be applied to areas where directional illumination is required. From this point of view, at this stage, in the field of indoor lighting, LEDs are more advantageous for spotlights and downlights than halogen lamps and compact fluorescent lamps.
LED indoor lighting prospects
Talking about the future prospects of LED, Ren Yuanhui said: LED is still developing constantly, indoor lighting space is broad, and the future application prospect is bright. But there must be greater progress and corresponding research and exploration work to create conditions for application.
