- incandescent lamp

  

Concept: the incandescent lamp is the oldest of a lamp, the different purposes and requirements, structure and components of the incandescent lamp is different, it will be the low cost, good color rendering property, into thousands of households, is currently should have a wide range of lamps.
Working principle: when the lamp is connected to the circuit, current through the filament, the thermal effect of the current, the incandescent lamp emits a continuous visible light and infrared ray, this phenomenon in the filament temperature up to 700K can be aware of, but because the filament temperature is high, the energy in the infrared radiation will be wasted, the rapid evaporation, the service life is shortened.
- fluorescent lamp
The concept of fluorescent lamp and fluorescent lamp is simple, that is a closed gas discharge tube, the main gas pipe for argon (argon) gas (containing neon or krypton other neon krypton) about 0.3% atmospheric pressure. Also contains a few drops of mercury - the formation of trace amounts of mercury vapor.
Working principle: Using low pressure mercury vapor release of ultraviolet rays in power, so that the phosphors emit visible light emitting principle, so it belongs to low pressure arc discharge light source.

  - LED lamp
Concept: also called light emitting diode, it is a solid semiconductor devices, can be directly converted into light.
Working principle: the heart of LED is a semiconductor chip, one end of the chip is attached to a support, one end is a negative electrode, the other end is connected to the positive electrode of the power supply, so that the whole chip is encapsulated by epoxy resin. Semiconductor chip is composed of three parts, one part is P type semiconductor, in which the dominant hole, the other end is N type semiconductor, here is mainly electronic, in the middle is usually 1 to 5 cycles of quantum wells. When the current is acting on the chip through the wire, the electrons and holes will be pushed to the quantum well, which will be combined with the hole in the quantum well, and then the energy will be emitted in the form of a photon.
