Description

The LED down of improved radiator structure

Technical field

This utility model relates to lighting field, particularly relates to a kind of LED down improving heat spreader structures.

Background technology

Under the background that global energy shortage, environmental requirement improve constantly, green energy conservation illumination is all greatly developed in countries in the world. LED illumination, as a kind of revolutionary energy-saving illumination technology, develops rapidly. LED is a kind of green light fixture generally acknowledged at present, and it mainly adopts direct current supply, and therefore it does not have scintillation in use; And its good stability, 100,000 hours, light decay was initial 50%; High-effect, the relative electric filament lamp of energy consumed when with light efficiency reduces 80%; The suitability is strong, and volume is little, and each unit LEDs small pieces are the squares of 3 to 5 millimeters, it is possible to makes variously-shaped device, and is suitable for the environment of mutability; Response time is fast, and the response time of electric filament lamp is millisecond, and the response time of LED is nanosecond; Environmental pollution is little, without poisonous metal hydrargyrum; Colour gamut is wide, it is possible to by chemical modification method, adjust band structure and the energy gap of material, it is achieved red, yellow, green and blue orange is multicolor luminous; The price of LED is more and more popular, and because of the characteristic of LED power saving, perhaps in the near future, people can change LED into electric filament lamp, and the place such as China's urban highway, school, plant area has changed the outfit LED.

LED down belongs to directional type lighting, only its opposite ability light, and beam angle belongs to optically focused, and light relatively collects Shen, and comparison of light and shade is strong, more prominent illuminated object, more sets off out required ambiance. Heat dissipation problem is always up restricting the technical barrier of this LED down development, has to be balanced between life of product and radiating effect for this LED designers.Existing LED down generally comprises LED light source module and optical processing unit, and arranges a heat abstractor at the back side of LED light source module. Described heat abstractor is generally multiple fin, adopts the mode of free convection to dispel the heat. In order to improve radiating effect, inventors suggest that on heat abstractor, set up graphite radiating block, such as application number: the LED down of this strengthening heat radiation disclosed in 201020125022.8. Described graphite radiating block is arranged on back of circuit board, is placed in the cavity of fin composition. Described scheme improves radiating effect to a certain extent, extends the life-span of light fixture. Although but joining of graphite radiating block allows the radiating effect of radiator more go a step further, but increase graphite radiating block and corresponding fixed structure can increase cost on light fixture. And due to the defect of this Down lamp fin itself, radiating effect is also be worth discussion. Therefore it provides the better LED down of a kind of radiating effect technical problem that to be those skilled in the art in the urgent need to address.
