Further, described upper cover plate is provided with ventilating opening.

Upper cover plate arranges ventilating opening, can strengthen air flow property, particularly during LED lamp work, radiator heating makes air expansion rise, and the ventilating opening that upper cover plate is arranged is conducive to air rising flowing, improves radiating efficiency.Vent design becomes different shapes, as radial, petal etc., can also have certain decorative effect.

Concrete, described upper cover plate and diffusion shell joint are rectangle.

The LED lamp of this programme, upper cover plate and diffusion shell joint are rectangle, are a kind of LED lamp of rectangular configuration, can install more LED chip as required, be applicable to making the ornament lamps such as powerful ceiling light.

Preferably, described rectangle is long and wide equal.

This is a kind of LED lamp of square structure, and more common rectangular configuration has more both artistic and practical contour structures.

Further, described radiator forms a circle along described rectangle perimeter.

For the LED lamp of rectangular configuration, radiator forms a circle along described rectangle perimeter, can increase the area of dissipation of radiator, improves radiating efficiency.

Recommend, described upper cover plate and diffusion shell joint are circular.

This is a kind of LED lamp of circular configuration, is also a kind of commonplace LED lamp structure form.

Further, described radiator forms a circle along described circular periphery.

Same, for the LED lamp of circular configuration, radiator forms a circle along circular periphery, also can increase the area of dissipation of radiator, improves radiating efficiency.

The beneficial effects of the utility model are, fully optimize the structure of LED illumination lamp, improve the radiating efficiency of radiator.The utility model has given full play to parts function in LED lamp, and radiator both had heat sinking function, has again the function of structural member, is linked together by upper and lower for light fixture two parts.
