A kind of ffu LED keel clean lamp and its processing technology

Abstract

The invention discloses an LED FFU keel clean lamp and its processing technology. The clean lamp is installed in the keel, and the clean lamp forms the ceiling of the clean room through the keel, the color steel plate and the FFU filter fan; the described The clean light includes a light source assembly, a light-transmitting cover, a heat-conducting gasket and a connector. The light source assembly includes a PCB board and an LED light source. The processing technology of the keel clean light is the processing technology of the light-transmitting cover, which diffuses PC plastic After preheating and drying, add it into the extruder, and then go through the steps of adjusting parameters→extruding molding→shaping→cooling→tracting→cutting to obtain the finished light-transmitting cover; It will occupy other space, the quality of the transparent cover is stable, its weather resistance and aging resistance can fully meet the requirements of the diffusion PC's own characteristics, and completely eliminate the inherent hidden dangers of the product; the structural design is novel and reasonable, simple and beautiful, and easy to install and disassemble.

Description

technical field [0001] The invention relates to the technical field of semiconductor lighting, in particular to an FFU LED keel clean lamp with long energy-saving service life, higher luminous efficiency, and convenient disassembly and assembly, and a processing technology thereof. Background technique [0002] The top of the clean workshop is composed of keels, color steel plates, lighting fixtures and FFU. The FFU is a fan filter unit unit, that is, a fan and a filter (high-efficiency filter (HEPA) or ultra-high-efficiency filter (ULPA)) are combined in Together, it forms the terminal purification equipment powered by itself, which is a modular terminal air supply device with its own power and filtering function. [0003] Most of the lighting used in clean workshops are embedded traditional clean lights such as Figure 4 As shown, the commonly used size of this kind of traditional clean lamp is 600×1200, which occupies relatively large ceiling space, and more FFU filter fa...

Problems solved by technology

Defects of the traditional water-cooled shaping production process: the cooling method is generally water-cooled, and the product is free from stress after being plasticized at high temperature from the extruder to the die. , leading to the inconsistency of the molecular structure between the surface and the bottom of the product out of the water sizing mold, resulting in internal stress

It is manifested in that the straightness of the product and the opening size of the product cannot be accurately controlled, and such a product is subjected to heat conduction from the light during actual use, causing the internal stress of the lampshade profile to be released prematurely and quickly. After the internal stress of the lampshade is released When it reaches a certain value, the lampshade will be cracked and scrapped.
