The utility model discloses further set up to: the first heat dissipation hole and the second heat dissipation hole are not on the same plane.

Through adopting above-mentioned technical scheme, because first louvre and second louvre are not on the coplanar, the holistic leakproofness of lamp shade has been strengthened to a certain extent, can prevent that the dust from directly getting into inside the lamp shade, influencing the use of LED lamp.

The utility model discloses further set up to: the first radiating holes and the second radiating holes are arranged in a plurality of numbers and are uniformly distributed in the high-temperature-resistant lampshade.

By adopting the technical scheme, the first heat dissipation holes and the second heat dissipation holes are arranged in a plurality of ways, so that the air circulation area is increased, and the heat dissipation speed is improved.

The utility model discloses further set up to: the fin material is aluminum alloy.

Through adopting above-mentioned technical scheme, because the fin material is the aluminum alloy, the aluminum alloy is silvery white, has the non-light tight effect in addition when guaranteeing the radiating effect, and the setting of fin can not influence the light transmissivity of LED lamp promptly.

The utility model discloses further set up to: the surface of the radiating fin is frosted.

By adopting the technical scheme, the surface of the radiating fin is frosted, so that the direct light of the LED lamp can be dispersed, the light of the LED lamp is scattered, and the LED lamp is prevented from generating glare.

The utility model discloses further set up to: the heat dissipation fins are multiple and arranged in the cavity.

By adopting the technical scheme, as the radiating fins are multiple and are arranged in the cavity, the heat absorption area of the radiating fins is increased, the heat generated by the light emission of the LED lamp is greatly absorbed by the radiating fins, the heat in the lampshade is reduced, and the normal use of the LED lamp is protected.

To sum up, the utility model discloses a beneficial technological effect does: the heat dissipation performance of the LED lamp is effectively enhanced, the normal use of the LED lamp is not influenced, and meanwhile, the LED lamp can be prevented from generating glare.
