Described thermal component is radiating tube, described radiating tube is the semicircle tubulose, described lampshade is the semicircle arcuation lampshade that is complementary and is fastened and connected with described radiating tube, described PCB is produced on described radiating tube on the plane of described lampshade, described radiating tube and lampshade two ends are equipped with terminal conducting joint, the led drive circuit that described terminal conducting joint links to each other.

The material of described thermal component is aluminium, aluminium alloy, copper, heat conduction plastic cement or pottery.

Described radiating tube inner surface is provided with the heat sink strip that protrudes with described radiating tube inner surface along axis direction.

Described heat sink strip and described radiating tube are structure as a whole.

Because the pcb board in the LED light fixture directly is produced on the surface of thermal component, so just so that PCB and thermal component are an overall structure, when LED is installed on the PCB, be that LED is directly installed on the thermal component, the heat of LED conducts and distribute heat with regard to direct thermal component by the LED lamp like this, radiating effect is very good, has improved the service life of LED light fixture.

In addition, because the material of thermal component is aluminium, aluminium alloy, copper, heat conduction plastic cement or pottery, the heat-conducting effect of these materials is very good, has further improved the heat conduction of LED light fixture and has distributed effect.

In addition, owing at the radiating tube inner surface heat sink strip being arranged, heat sink strip has increased the cooling surface area of radiating tube, thereby has improved the radiating efficiency of radiating tube.

In addition, because heat sink strip and radiating tube are structure as a whole, be convenient to like this processing and manufacturing, reduced production cost.

In addition, because lampshade is plastic material, the transmitance of the light of plastics is very high, and very light in weight, has increased the brightness of LED light fixture and has reduced the weight of LED light fixture.

The LED light fixture that the utility model provides has been cancelled the pcb board in the prior art LED light fixture, be applicable to all kinds of LED lightings such as bulb lamp, lamp affixed to the ceiling, Recessed light, Down lamp, fluorescent lamp, MR16, E20, E22, can select the LED lamp of different capacity can contain 4 watts to 750 watts power bracket

Fluorescent lamp in the LED light fixture that the utility model provides comprises indoor, outdoor, commercial and water-bed use LED light fixture, the LED light fixture of T5, T6, T8, T9, T10 and all lengths specification.

[specific embodiment]

Below in conjunction with drawings and Examples the utility model is further described.

The utility model LED fitting structure cutaway view is referring to Fig. 2, comprise radiating tube 1, is connected with radiating tube and cooperates and lampshade 2 that buckle connects, at radiating tube 1 towards face on the left and right sides of lampshade 2 PCB3, at PCB3 LED lamp 4 is installed, the heat sink strip 5 that two symmetries are arranged along the axis direction of radiating tube 1 at radiating tube 1 inner surface has two buckle structures 6 in the junction of radiating tube 1 and lampshade 2; Because PCB3 directly is produced on the surface of radiating tube 1, when the LED lamp was installed in PCB when upper, be equivalent to the LED lamp and be directly installed on the radiating tube, the heat on the LED connects a directly conduction radiating tube, heat transfer efficiency will improve like this, thereby has increased the service life of LED light fixture; The heat sink strip that protrudes from addition the radiating tube surface on radiating tube is arranged again, the increase of heat sink strip, meeting will improve the radiating efficiency of radiating tube like this, thereby improve the radiating efficiency of whole LED light fixture so that the surface area of radiating tube increases; Heat sink strip and radiating tube are structure as a whole, and can by mode time processing moulding such as casting processing, improve working (machining) efficiency; Installation and the maintenance of the very convenient LED light fixture of the buckle structure of radiating tube and lampshade, and efficient is very high.The material of radiating tube is aluminium alloy in this implementation column, because aluminium alloy has efficient heat conductivity, so radiating effect is just very good, and in actual applications also can selection rate, the good materials of heat conductivility such as copper, heat conduction plastic cement, pottery.
