Description

A kind of LED seat composition being easy to dispel the heat

Technical field

The present invention relates to LED technical field, be specifically related to a kind of LED seat composition being easy to dispel the heat.

Background technology

Under the background that Present Global energy starved worry raises once again, save energy is the important problem that we will face future, at lighting field, the application of LED luminous product is just attract the sight of common people, LED has the many merits such as light efficiency is high, long service life, energy-saving and environmental protection, is more and more widely used in various fields.It is the new type light source of 21 century, has the advantage that the conventional light source such as efficiency is high, life-span length, not cracky cannot compare with it.When adding forward voltage, light-emitting diodes physical efficiency sends monochrome, discontinuous light, and this is the one of electroluminescent effect.Change the chemical composition of the semiconductor material adopted, light-emittingdiode can be made to be emitted in near-ultraviolet ray, visible ray or ultrared light.Because LED makes voltage low (only 1.5-3V), can active illuminating and have certain brightness, brightness can use again voltage (or electric current) to regulate, shock-resistant, anti-vibration again itself, life-span are long, therefore increasing application is served in display field, especially utilize in fluorescent lamp field, there is the technological merit that brightness is high, the life-span is long.

In order to adapt to the trend of energy-conserving and environment-protective, LED is brought into use to replace incandescent light and luminescent lamp to do light source in the market.But the lamp socket that the various LED of selling in existing market use and base are plastics or metal construction, and its manufacturing cost is higher, and heat dispersion is poor, and moisture resistance, corrosion resistance are bad, cause the work-ing life of LED shorter, can not meet market demand.
