[background technology]

The basic difference of LED and conventional light source is: conventional light source belongs to the luminescence process heat build-up of need trying one's best, and for example, fluorescent lamp is when being cold, and is slow when starting than being warm, and starts the back because fluorescent tube heat inadequately, and incipient stage brightness is also dark specific heat the time; And LED is technological as a kind of semiconductor lighting, and the main cause that its illumination functions lost efficacy was a fire damage, so the essential heat radiation as soon as possible as far as possible of led light source.

Existing LED fluorescent lamp holder structure is that dull and stereotyped lamp holder is direct insertion, and its junction is seamless, causes the thermal diffusivity of lamp holder relatively poor, thereby influences its illumination effect and service life.

In recent years, white light LEDs its luminous efficiency when extension and chip technology improve constantly is increased dramatically, and has broken through the technical bottleneck of 100lm/W at present.Along with the decree that each national successively issue incandescent lamp prohibits selling, the LED lighting with advantages such as energy-saving and environmental protection, long-lives progressively gets into commercial lighting, general lighting field.The LED fluorescent lamp is typical a kind of light fixture in the indoor illumination light fitting, has outstanding advantage: 1. luminous efficiency is high, and power consumption is low, compares the conventional fluorescent fluorescent tube and can save electric weight more than 60%; 2. can select different changes in temperature white light tones according to concrete environment for use; 3. the LED fluorescent lamp does not need electric ballast and starter, and the response time is fast; 4. the LED fluorescent lamp does not use harmful substances such as mercury, helps to improve environmental sanitation and living conditions.

The LED light fixture has advantages such as energy conversion efficiency is high, on-off effect speed is fast, the life-span long, radiationless and low in energy consumption and is widely used.Existing LED light fixture has a lamp socket usually and is plugged in the LED fluorescent lamp on the said lamp socket; Said LED fluorescent lamp has the good LED fluorescent lamp heat radiation device of a thermal diffusivity, a lampshade, a led light source module and two lamp holders; Said led light source module has an aluminium base and is fixed on the some LED lamps on the said aluminium base; Said lampshade is fixed on the said heat dissipation metal body; The both sides of said aluminium base link to each other with the good LED fluorescent lamp heat radiation device of said thermal diffusivity, and the LED fluorescent lamp heat radiation device that the upper surface of said aluminium base and said thermal diffusivity are good keeps certain distance, and said lamp holder is fixed on the said heat dissipation metal body.And for example number of patent application is that 200920130789 Chinese patent has disclosed similar device.Yet because the upper surface of said aluminium base keeps certain distance with the good LED fluorescent lamp heat radiation device of said thermal diffusivity, thereby heat can not in time spread out of, thereby lacks in heat dispersion difference and service life.
