Description
Technical field
The utility model relates to a kind of LED liquid crystal display module.
Background technology
The technology of the LED-backlit module of present usefulness is comparative maturity, the design of each family is similar, all be to be the main components of module backlight by preceding frame, center, backboard, it is the demonstration that a complete liquid crystal module realizes picture image that fixed support blooming piece, LED lamp bar and glass are played in their combination.Wherein LED lamp bar is the element that produces light source, well-known under present technical merit condition, relatively lower about 20% of the total energy consumption that only accounts for of the luminescence efficiency of LED lamp (light emitting diode), all the other Conversion of energy of about 80% are heat energy, the LED liquid crystal display product of a superior performance does not wish that it works long hours under the environment of high temperature, the composite wood brightening piece, following diffusion sheet, light guide plate, reflector plate is worked under hot environment for a long time and can be produced distortion, bad phenomenon such as variable color jaundice, LED lamp (light emitting diode) is worked under hot environment for a long time and can be shortened its life-span simultaneously, so just the LED liquid crystal display product is especially had higher requirement to the heat radiation of LED-backlit module, existing technology generally all is to adopt LED lamp bar is attached what five metals backboard by heat-conducting glue, the heat energy that the LED lamp is produced when work is transmitted to by heat-conducting glue on the five metals backboard, has just gathered a large amount of heat energy on the five metals backboard like this.By composite wood brightening piece known to preceding chatting, following diffusion sheet, light guide plate, reflector plate is worked under hot environment for a long time and can be produced distortion, bad phenomenon such as variable color jaundice, and reflector plate generally is close to what five metals backboard, the heat energy that is gathered on the five metals backboard will be directly transferred to reflector plate like this, reflector plate is worked under hot environment for a long time and can be produced distortion, bad phenomenon such as variable color jaundice, simultaneously general its heat transfer efficiency of five metals backboard is low, the heat energy that is produced during LED lamp operate as normal is difficult for distributing, thereby the LED lamp is worked long hours under the what hot environment, and this will shorten its serviceable life greatly.
The utility model content
The purpose of this utility model is, provides a kind of and substitutes the heat radiation that traditional LED-backlit module uses the five metals backboard with aluminium section bar as main radiating element.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: a kind of LED liquid crystal display module comprises acetate tape or has viscosity insulating trip, glass, silicagel pad, LED assembly, aluminium section bar A, aluminium section bar B, aluminium section bar C, aluminium section bar D, comprehensive brightening piece, following diffusion sheet, light guide plate, reflector plate, backboard; Aluminium section bar A and aluminium section bar B, aluminium section bar B and aluminium section bar D, aluminium section bar D and aluminium section bar C, aluminium section bar C and aluminium section bar A fix with screw respectively, then with it with screw fixedly on the what backboard, backboard the place ahead is a reflector plate, reflector plate the place ahead is provided with light guide plate, light guide plate the place ahead is following diffusion sheet, following diffusion sheet the place ahead is comprehensive brightening piece, and the forefront is with the fixing glass on the what aluminium section bar of acetate tape.
LED lamp bar assembly is by heat-conducting glue fixedly on the what aluminium section bar C.
Be silicagel pad between aluminium section bar A, aluminium section bar B, aluminium section bar C, aluminium section bar D and the glass, silicagel pad is used for cover glass and plays buffer action
Aluminium section bar C outside surface is made as the shape of dentation.
The heat energy that the LED lamp is produced when work is transmitted to by heat-conducting glue on aluminium section bar C, owing to be made as the shape of dentation on the aluminium section bar C outside surface, thus the external surface area that has increased aluminium section bar increases its radiating efficiency.The radiating efficiency of aluminium section bar is better than general five metals backboard far away, the heat energy that the LED lamp is produced when work is concentrated by aluminium section bar and is distributed in the what outside air, thereby avoided heat energy to make reflector plate temperature distortion jaundice variable color etc. bad, also guaranteed the serviceable life of LED lamp by five metals backboard conduction what reflector plate.
The beneficial effects of the utility model are: simple in structure, substitute the heat radiation that traditional LED-backlit module uses the five metals backboard with aluminium section bar as main radiating element, increase the radiating effect of LED lamp greatly, thereby avoided heat energy to make reflector plate temperature distortion jaundice variable color etc. bad, also guaranteed the serviceable life of LED lamp by five metals backboard conduction what reflector plate.
