Incandescent lamp, energy saving lamps, LED lights, what each is? How's the difference?
Incandescent lamp，Incandescent lamp filament electrically heated to incandescence lamp by thermal radiation electric light source emits visible light. Since 1879, the United States of TA Edison made the carbon fiber (ie carbon filament) incandescent filament material by people, filament structure, continue to improve the filling gas, the luminous efficiency of incandescent lamps have been increased. In 1959, the United States developed on the basis of incandescent light volume and the decline of small halogen lamps. The main trends is to develop energy-efficient incandescent bulbs. Incandescent different uses and requirements, the structure and components vary. Incandescent light efficiency was low, but good light color and set light performance, the largest output, the most widely used electric light.
Energy saving lamps，Also known as energy saving light bulbs, electronic light bulbs, compact LED Tube Light and one fluorescent, fluorescent lamps and ballasts means (ballast) are combined into an overall lighting. Energy-saving lamps and incandescent lamps of similar size, and lamp and incandescent identical interfaces, so it can directly replace incandescent lamps. Light efficiency energy saving lamps is much higher than incandescent lamps, under the same lighting conditions, the former consume much less power, so called energy saving lamps.
LED lights，Light Emitting Diode，Is a solid state semiconductor devices, which can be converted directly into electricity to light. LED's heart is the end of a semiconductor wafer, the wafer is attached to a bracket, one end is negative, and the other end connected to the positive power supply, so that the whole chip is epoxy encapsulated. Semiconductor chip consists of two parts, part of P-type semiconductor, the hole in it dominates the other side is N-type semiconductor, LED light manufacturers here is mainly electronic. But when the two semiconductor connected to form a PN junction between them. When the current through the wire act on the chip, the electron will be pushed to P zone electron hole recombination, and then will be issued in the form of photon energy in the P area, this is the principle of LED light. The wavelength of light that is the color of light is determined by the material form a PN junction of the decision.
