Where is the difference between the LED lamp belt and the ordinary lamp?
The light emitting principle of LED soft light band is different from that of incandescent lamp and gas discharge lamp,The energy conversion efficiency of LED soft light band is very high, and the energy consumption of incandescent lamp can reach 10% in theory,LED soft light band, compared to fluorescent lamp can also achieve 50% energy saving effect. Energy saving effect is remarkable, which is of great significance to China, which is very energy intensive. The utility model does not contain toxic and harmful substances (such as mercury), avoids the two pollution of the fluorescent tube rupture and overflows mercury, and simultaneously does not interfere with radiation.Besides the optical properties of light, compared with incandescent and fluorescent lamps, 1 LED light less, using a plurality of LED.LED itself so require radiation range with a light emitting area is small, light, with advantages of light in a hemisphere distribution of rotational symmetry, plus lenses and mirrors, can constitute a a good source.
Thermal characteristics LED soft band with little heating, LED use cold lighting technology, heating capacity is much lower than ordinary lighting.LED soft lamp with DC drive, ultra low power (single tube 0.03-0.06 Watt) electro-optical power conversion is close to 100%, the same lighting effect than traditional light source energy saving more than 80%. Because it has no filament, so no filament burn thermaldeposition disadvantages such as light fades.
Electrical characteristics LED soft light belt power supply and incandescent lamp, fluorescent lamp is very different. The incandescent lamp can be directly connected to the alternating current of the 220V. Although there are ballasts and switches for fluorescent lamps, they also use 220V alternating current. The LED power supply requires a constant DC current, so the AC 220V is converted to dc. The efficiency of the power supply is not high, will directly affect the efficiency of the entire lighting, so improving the efficiency of the power supply is very important for improving the efficiency of the LED soft light band lighting.
