Mining explosion-proof led roadway lights

Abstract

The invention relates to a mineral flameproof LED (Light Emitting Diode) roadway lamp comprising a lamp housing, two rear covers (a rear cover 9 and a rear cover 11) which are installed on the back surface of the lamp housing, a copper lining plate, toughened glass and a lens which are installed on the front surface (a light source cavity) of the lamp housing and two cable introducing devices installed on the lamp housing. One light source cavity is arranged on the front surface of the lamp housing, two cavities (a wiring cavity and an electric appliance cavity) are arranged on the back surface of the lamp housing, the wiring cavity is connected with the light source cavity through two insulating screws, and the electric appliance cavity is connected with the light source cavity through four binding posts to form three completely independent cavities. The electric appliance cavity and the wiring cavity are arranged on the left and right side by side and form an upper layer and a lower layer with the light source cavity, thereby reducing the height of a light fitting and facilitating the underground embedded installation. The electric appliance cavity is connected with the light source cavity through the four binding posts and is located at a completely independent state, so that the heat of the light source cavity cannot enter the electric appliance cavity to guarantee the temperature of the electric appliance cavity to locate at the lowest state (environmental temperature) so as to effectively guarantee the service lives of capacitors and elements and components on an LED drive board.

Description

technical field [0001] The present invention relates to a roadway lighting lamp, more specifically to an LED roadway lamp which is especially suitable for use in coal mine underground roadways Background technique [0002] At present, the LED roadway lights used in underground roadways all adopt upper, middle and lower structures. Due to structural defects, the lamps are too long or too high, and the lamps cannot be installed embedded; the working environment temperature of the LED driver board is high, and the service life is shortened. . It affects the lighting needs of coal mines, brings a lot of inconvenience to production activities, and seriously affects production efficiency. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a mining explosion-proof LED roadway light that solves the problem of high temperature in the working environment of the LED drive board, shortened lifespan and inconvenient embedded in...
