Light is emitted from the SMD LED and diffuses through the inner side wall 8 to the outer side wall 9 to form a square light spot.

[0020] The bottom of the heat dissipation housing 1 is provided with a long opening gradually widening from the inside to the outside of the installation cavity 10, and the light board 3 and the lens 4 are installed in the installation cavity 10. Heat dissipation stripes are provided on the reverse side of the inner bottom of the installation cavity to assist in quickly transferring the heat in the installation cavity to the outside of the heat dissipation housing. Heat dissipation stripes 11 are provided on the surface of the top of the heat dissipation housing 1. The interior of the heat dissipation housing 1 is a plurality of cavities divided by a plurality of criss-cross partitions 16, which reduces the overall weight, strengthens the overall strength and increases the area of ​​heat transfer. The heat dissipation housing 1 is generally set to aluminum or other heat dissipation materials.
