Abstract
The utility model discloses a low-power LED indoor illuminating lamp comprising an LED chip. The LED chip is fixedly mounted on an Al-based printed circuit board (PCB); and a heat radiation device is arranged on the back side of the Al-based PCB. The utility model has the advantages of simple structure, good heat radiating effect, and long service life.
Description
Technical field
The utility model relates to a kind of low-power LED indoor illumination.
Background technology
The white semiconductor LED has multinomial advantages such as energy-saving and environmental protection, life-span length, development in recent years is rapid, be called as the 4th generation lighting source, be the revolution of throwing light on for the third time, replace incandescent in 10 years from now on probably, fluorescent lamp and become the main stream light sources of illumination.Countries in the world comprise that Chinese Government is all wideling popularize this new type light source that helps energy-conservation medal.
In low-power LED application facet such as desk lamp, fluorescent lamps, the factor affecting of being dispelled the heat adopts every power on 0.06w left and right sides Φ 5mm straw hat type LED lamp pearl mostly at present.A light fixture just needs tens to a hundreds of small lamp bulb, and lamp power is not allowed to be easy to do greatly, and heat dissipation problem has become the bottleneck of indoor lamps such as LED desk lamp, fluorescent lamp development simultaneously.
The utility model content
The purpose of this utility model is to provide a kind of low-power LED indoor illumination, and it is simple in structure, good heat dissipation effect, long service life.
The purpose of this utility model is achieved in that a kind of low-power LED indoor illumination, comprises led chip, and led chip is fixedly mounted on the aluminum-base printing circuit board, and the back side of aluminum-base printing circuit board has heat abstractor.
The utility model adopts the low-down aluminum-base printing circuit board of thermal resistance to substitute the common printed circuit board of current a large amount of uses, it both can play the effect that is electrically connected, can play extraordinary conductive force again, the heat that can rapidly led chip be produced is taken away, make the led chip temperature rise unlikely too high, will lose efficacy because the led chip temperature reaches 120 ℃.During production, led chip is welded on the aluminum-base printing circuit board, directly be fixed on aluminum-base printing circuit board on the radiator again, heat dissipation problem is resolved like this, prolonged service life greatly, can adopt the high-power LED chip of 0.5w～1w, the power of light fixture and light efficiency are significantly improved, obviously be better than the desk lamp and the fluorescent lamp of common use.The utility model is simple in structure, is easy to manufacture good heat dissipation effect.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Accompanying drawing is that master of the present utility model looks cross-sectional view.
The specific embodiment
A kind of low-power LED indoor illumination as shown in drawings, comprises led chip 5, and led chip 5 is fixedly mounted on the aluminum-base printing circuit board 3, and the back side of aluminum-base printing circuit board 3 has heat abstractor 6.
Said heat abstractor 6 is aluminium radiator fin or copper radiating rib.
The cross section of said heat abstractor 6 is a H shape, and said led chip 5 and aluminum-base printing circuit board 3 are installed in the side groove of heat abstractor 6, the uniform radiating fin 1 that is being provided with in the opposite side groove of heat abstractor 6.
Between led chip 5 and aluminum-base printing circuit board 3, heat-conducting silicone grease layer 4 is being set.
One deck heat-conducting silicone grease layer 2 also is being set between aluminum-base printing circuit board 3 and heat abstractor 6.
Said led chip 5 is encapsulated in the transparent shield 7.
Said transparent shield 7 is for to be made of toughened glass panel.
When led chip 5 work, the heat that it produced is transmitted to rapidly on the good aluminum-base printing circuit board of heat conduction 3.Be transmitted on the radiator 6 by aluminum-base printing circuit board 3, radiator 6 is very big with the contact area of air, this heat can be lost to rapidly in the middle of the air again.Actual measurement is when led chip 5 work, and the spreader surface temperature of this light fixture is the highest can not to surpass 65 ℃, thereby can guarantee led chip work reliably steady in a long-term.
Because the LED lamp uses the dc constant current power supply power supply, therefore, luminous stable no stroboscopic; It does not have ultraviolet ray its luminescence mechanism decision, infrared radiation, and free from glare, colour rendering index height, brightness are evenly near natural daylight, good visual effect, but continuous operation 50000-100000 hour, life-span is long, and the pollution of harmful element such as unleaded, mercury meets the ROHS standard; Can be called high brightness, energy-saving and environmental protection, long-life eye-protecting lamp.Be specially adapted to school, office, domestic lighting use.
Because that the LED light fixture has is low in energy consumption, the life-span is long, light efficiency is high, photochromic pure, reaction is fast, good stability, Security is good, radiationless, pollution-free, antidetonation, the advantages such as anti-strike. Day by day serious in the global energy shortage Today, actively the novel LED lighting of development and popularization will have great social benefit and economy Benefit.
