Illuminating lamp special for refrigeration house

Abstract

The illumination lamp comprises a full-sealed shell, the full-sealed shell comprises a square pipe body, a left plug and a right plug, a through groove is formed in the square pipe body, the left end and the right end of the through groove both penetrate out of the square pipe body, the left plug covers the left end of the through groove, and the right plug covers the right end of the through groove; a first silica gel ring is installed between the left plug and the square tube body in an extrusion mode, a second silica gel ring is installed between the right plug and the square tube body in an extrusion mode, an LED lamp panel, a control module, a constant-current power source and a constant-voltage power source are installed in the through groove in a clearance fit mode, the LED lamp panel is connected with the constant-current power source, and a plurality of heating elements are installed on the LED lamp panel in an embedded mode. The control module is connected with the heating element through a constant-voltage power supply, a respirator and a waterproof connector are embedded in the left plug, and the inner ends of the respirator and the waterproof connector are both communicated with the through groove; the invention has the advantages of energy conservation, high efficiency, prolonged service life, no frosting on the surface of the lamp, and improved lighting effect.

Description

technical field [0001] The invention relates to the field of cold storage lighting, in particular to a lighting fixture specially used for cold storage. Background technique [0002] At present, most of the lamps used in cold storage are lamps with high power consumption and high heat such as incandescent lamps and metal halide lamps. High power can no longer meet the national policy of energy conservation and emission reduction. However, the high heat leads to a large temperature difference between the inside and the outside when the light is turned on and after the light is turned off. The surface of the light body is easy to burst, and the service life is extremely short. Usually 6-10 months need to replace the lamps and lanterns, not energy-saving but also increased replacement costs. [0003] As a new generation of energy-saving light source, LED is limited by the low temperature environment in cold storage and cannot work completely and stably when used in cold stora...
