Is LED lighting lighting, LED lighting lamp act the role ofing is a solid light-emitting semiconductor devices. It is the use of solid semiconductor chip as a luminescent material, through the carrier in the semiconductor photon emission caused by the compound gives off excess energy between, directly from red, yellow, blue, green, blue, orange, purple, white light. LED lighting products are created using LED as light source lighting appliances
LED the emergence of broke the traditional design method of the light source and the train of thought, there are two kinds of the latest design concept
1. Lighting: based on the environment demand to design the lamps and lanterns. Take place as a starting point to build a beautiful, brilliant light environment, to foil scene effect, make the person feel the scene atmosphere.
2. Emotional appeal lighting: based on the needs of the lamps and lanterns to design. With emotion as a starting point, from the perspective of people to create a kind of artistic conception of lighting conditions. Mood lighting and lighting, lighting is dynamic, emotional appeal lighting system can satisfy the spiritual needs of people, make the person feel the emotional appeal; And lighting is static, it can only emphasize the demand of the scene illumination, but cannot express the person's mood, in a sense, emotional appeal lighting lighting.
Semiconductor light-emitting diode (LED) as third-generation semiconductor lighting source. This product has many advantages: (1) like dream high light efficiency: almost all concentrated in the visible light frequency spectrum, efficiency can reach 80% 90%. And photosynthetic efficiency almost incandescent lamp light efficiency of 10% to 10%. (2) high quality light: as there is no ultraviolet and infrared spectrum, so there's no heat, no radiation, belongs to typical green lighting source. (3) the energy consumption of small: monomer is in commonly 0.05 1 w, by way of cluster can be tailored to meet the needs of different, little waste. With its as the light source, under the same brightness, power consumption is only 1/8 of the ordinary incandescent lamp, 10. (4) long life: luminous flux decay to 70% of the normal lifespan is 100000 hours. A semiconductor light under normal circumstances can be used for 50 years, even if the long life, life will use at most 2 only light. (5) the reliable and durable: no tungsten filament, such as glass shell parts, which are easily damaged, abnormal scrap rate is very small, maintenance cost is very low. Flexible (6) application: small volume, can be flat packaging, easy to develop into a lightweight products, make a point, line, face all kinds of specific application of products. (7) security: unit work roughly between 1.5-5 v voltage, working current is between 20 to 70 ma. (8) of green environmental protection: waste recycling, no pollution, do not like fluorescent lamp contains hg. (9) response time is short: to adapt to the frequent switch and the occasion of high-frequency operation.
