High-reliability LED (Light Emitting Diode) light

Abstract

The invention discloses a high-reliability LED (Light Emitting Diode) light which comprises a base plate and a light cover, wherein the light cover is covered above the base plate; a pressure sensitive adhesive layer is coated on the outer surface of the light cover, and a matte surface coating layer is coated on the surface of a polyester film layer; a plurality of air holes are formed in the pressure sensitive adhesive layer, and the density of the air holes is 2000 to 3000 per cubic centimeter; the surface roughness of the matte surface coating layer is 0.1 to 0.8 Mu. m; the pressure sensitive adhesive layer is composed of 100 parts of acrylate adhesive, 30 to 50 parts of diluent, 0.5 to 2 parts of isocyanate crosslinking agent, 0.5 to 2 parts of epoxy crosslinking agent, 5 to 20 parts of rosin resin, 2 to 15 parts of azoic compound, 2 to 15 parts of N-nitroso compound, 0.5 to 2 parts of coupling agent and 0.3 to 1.5 parts of acrylate polymer. By using the high-reliability LED light, the cracking probability of an LED light tube is greatly reduced, uniform and matte light is realized, and additionally, the adhesive force of the polyester film layer and the light cover is increased; the high-reliability LED light has high temperature resistant performance, and the reliability of the product performance is guaranteed.

Description

technical field [0001] The invention relates to a high-reliability LED lighting lamp, which belongs to the technical field of LED lighting lamps. Background technique [0002] LED can directly convert electricity into light. At the same time, LED has the characteristics of long life, high luminous efficiency, no radiation, impact resistance and low power consumption. In order to meet the requirements of energy saving and environmental protection, and to meet the needs of different users, more and more manufacturers have developed LED lamps to replace fluorescent lamps in traditional technology. [0003] The LED light tube is a row of LED light-emitting units installed inside the light-transmitting light tube. The technical problems of the existing technology are as follows: (1) There are problems and deficiencies such as poor light transmittance, large attenuation of transmitted light, and poor uniformity of the fog surface. ; (2) The LED lamp tube may be broken, which pose...
