Description
Technical field
The utility model relates to lamp plate, relates in particular to a kind of LED lamp plate.
Background technology
At present, the LED lamp has obtained huge development as light source of new generation, has become the emphasis high-tech new industry of national planning.And powerful lamp pearl is all adopted in the illumination of led function property, and its luminous efficiency has only 10%～25%, and remaining energy then is converted into heat energy; And the LED lamp is a semiconductor devices, is afraid of very much " heat ", if the heat energy in the LED lamp can not in time distribute, can quicken the aging of LED lamp, in case surpass the highest critical-temperature, tends to cause the permanent failure of LED lamp.LED lamp junction temperature is 5～10 times under 70 ℃ of work in the working life under 25 ℃, so heat dissipation technology is one of LED lamp key for design technology, also is the bottleneck technology of present industry.And industry all concentrates on radiator heat-dissipation with heat dissipation problem at present, has but ignored the heat dissipation problem of aluminium base and circuit design.The LED lamp plate is made up of the three-decker of uniquenesses such as PCB circuit layer, heat conductive insulating layer and aluminum base layer usually.The anodal pin of LED lamp pearl, negative pole pin respectively with the PCB circuit layer on cathode conductive film and cathode conductive film between be electrically connected, the heat that LED lamp pearl produces is transmitted to the heat conductive insulating layer through the PCB circuit layer, is transmitted to metal level again and arrives outside thermal component.Existing LED lamp plate only transmits through carrying out heat between anodal pin, negative pole pin and the PCB, so radiating effect is not good, and LED lamp easy ageing has shortened service life.
The utility model content
The technical problem that the utility model solves is: a kind of LED lamp plate that can improve heat dispersion is provided.
The technical scheme of the utility model is: a kind of LED lamp plate; Comprise PCB circuit layer, heat conductive insulating layer and aluminum base layer, said heat conductive insulating layer is between PCB circuit layer and aluminum base layer, and said PCB circuit layer is provided with some LED lamp pearls of series connection; Wherein each LED lamp pearl has anodal pin and negative pole pin respectively; It is characterized in that each LED lamp pearl also is provided with the metal fixing feet, the PCB circuit layer has some etched part that are used to install LED lamp pearl; Each etched part region is equipped with the heat sink plate that is used to dispel the heat; Said heat sink plate is fixed on the said heat conductive insulating layer, and the both sides of each heat sink plate are distributed with isolated conducting strip, and said conducting strip is positioned at said PCB circuit layer; The metal fixing feet of each LED lamp pearl is welded with a said heat sink plate respectively mutually, and the anodal pin of each LED lamp pearl, negative pole pin are electrically connected respectively with between the both sides conducting strip of corresponding heat sink plate.
The shape of said each heat sink plate is " worker " font.
The surface area of said heat sink plate is 115mm～120mm.
The beneficial effect of the utility model is:
Because LED lamp pearl is provided with the metal fixing feet; The PCB circuit layer has some etched part that are used to install LED lamp pearl, and each etched part region is equipped with the heat sink plate that is used to dispel the heat, and said heat sink plate is fixed on the said heat conductive insulating layer; The said heat sink plate of metal fixing feet of LED lamp pearl is welded mutually; The heat that LED lamp pearl produces not only continues to be delivered to the PCB circuit layer through anodal pin of LED lamp pearl and negative pole pin, and is delivered to the heat conductive insulating layer through the PCB circuit layer, dispels the heat but also can be delivered to heat sink plate through the metal fixing feet of LED lamp pearl; Therefore the utility model can improve the heat dispersion of LED lamp, prolongs the service life of LED lamp.
Because the shape of heat sink plate is " worker " font, in the contacted while of the conducting strip of avoiding heat sink plate and its both sides, can enlarge the surface area of heat sink plate, thereby improve the area of dissipation of heat sink plate, and then improve the heat dispersion of LED lamp.
