Dimmable LED track spotlight 4 wires
Features of Dimmable LED track spotlight 4 wires:
1, high efficiency and energy saving under the condition of the same brightness, LED buried lights, 1000 hours only 1 KWH, ordinary incandescent 17 hours 1 KWH, ordinary energy-saving lamps one hundred hours spent 1 KWH.
2, long life LED energy-saving lamps use theoretical service life of up to tens of thousands of hours, the service life of the ordinary incandescent lamp is more than 1000 hours.
3, the light health no ultraviolet and infrared light, no radiation, no pollution. Ordinary incandescent light bulbs, energy-saving lamp tube and contains ultraviolet and infrared light.
4, green environmental protection does not contain harmful elements such as mercury and lead, thanks to recycling and utilization, and won't produce electromagnetic interference.
5, protect eyesight driven by dc power supply, no stroboscopic, ordinary light is ac drives, is bound to produce stroboscopic adverse to the eyes for a long time.
6, high light efficiency heat is small, 90% of its electricity into visible light, only 20% of ordinary incandescent electric energy into visible light, the other 80% of electrical energy into heat for limited resources is a huge waste.

Q: How do you get more light out of an LED?
A: LEDs are made by a process that deposits the junction materials on a substrate material. One of the limitations of LEDs is that imperfections in the material deposited on the substrate reduce the efficiency. Improvements in the manufacturing process have given us brighter LEDs, as have new junction materials. To a certain extent, you can also make the junction larger to get more light. But you can't extend that very far, mainly due to those imperfections. Their accumulated effect prevents a junction from growing much bigger than a square millimeter. So we won't likely see larger LED junctions without some advance in materials science to overcome that limitation. Since a single LED is a relatively low power device (by comparison with other light sources), constructing LED arrays is attractive.
Q: How LED works?
A: An LED consists of a chip of semiconducting material treated to create a structure called a p-n (positive-negative) junction. When connected to a power source, current flows from the p-side or anode to the n-side, or cathode, but not in the reverse direction. Charge-carriers (electrons and electron holes) flow into the junction from electrodes. When an electron meets a hole, it falls into a lower energy level, and releases energy in the form of a photon (light).
