Specifically, since the light emitting element 20 generates a large amount of heat during the lighting process, the heat often has adverse effects on the light emitting element 20 or other components, that is, the service life of the lighting fixture of the present invention is affected, and the heat dissipating fins 12 are disposed on the side of the lamp housing 10 opposite to the lens 30, so that the heat dissipating fins 12 can timely and effectively absorb the heat emitted by the light emitting element 20 and dissipate the heat toward the outside, thereby effectively prolonging the service life of the lighting fixture of the present invention.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
