Title:
TRI-PROOF LAMP
Document Type and Number:
WIPO Patent Application WO/2022/193634
Kind Code:
A1
Abstract:
Disclosed is a tri-proof lamp comprising a first housing, characterized in that the tri-proof lamp further comprises a second housing arranged side by side with the first housing, wherein the first housing is a hollow housing formed by means of extrusion molding, the space in the first housing forms a light source cavity, a light source is arranged in the light source cavity; the second housing is also hollow, the space therein forms an electronics cavity, and a light-source driving module is arranged in the electronics cavity; and the light source cavity and the electronics cavity are isolated from each other, and the light source is electrically connected to the light-source driving module. Compared with the prior art, the present utility model has the advantages of the light source cavity being completely isolated from the electronics cavity, so that photoelectric separation is realized, and heat dissipated from the light source and electronics being dispersed, thereby facilitating heat dissipation and prolonging the service lives of the light source and a power supply; and the thinking that a traditional tri-proof lamp is mainly based on an injection molding process is shattered, and the tri-proof lamp of the present utility model is formed by combining the advantages of injection molding and extrusion molding processes, so that the light transmittance of the light source cavity formed by means of extrusion molding is much better than that of a light source cavity formed by means of injection molding, and the light-emitting effect is good.
