Abstract
The utility model relates to a PCB circuit board used in a LED lamp, wherein the PCB circuit board possesses good heat dissipation performance. According to the PCB circuit board used in the LED lamp, a first heat dissipation copper foil, a second heat dissipation copper foil and a control copper foil are designed to be a copper foil structure which is in an I shape or other shapes on the circuit board. According to the circuit board of the utility model, the more copper foils are used to contact with air or other heat dissipation medium. A heat dissipation area is greatly increased and a heat dissipation effect is greatly increased too. A junction temperature of a chip and a temperature difference of a lamp radiator are effectively reduced. Under the condition that the temperature of the lamp radiator is high, the junction temperature of a lamp bead chip is in a reasonable scope so that a large amount of heat dissipation materials can be reduced. Improvement of a heat dissipation capability is good for reduction of a heat dissipation device and cost saving. If an aluminum substrate is used, the heat dissipation capability to the air is increased and the heat dissipation capability of the lamp bead to the aluminum plate located at a lower place is increased too.
Description
Technical field
The utility model relates to a kind of board design of LED light fixture, more particularly, is the better LED light fixture PCB wiring board of a kind of heat dispersion.
Background technology
Light fixture aluminium base design in the market all is that a PCB by the lamp pearl encapsulates to design, Copper Foil area to following aluminium sheet heat radiation is very little like this, during the as a result aluminium sheet heat conduction of lamp pearl below aluminium base, thermal resistance is too large, thereby need the larger radiator of area of dissipation or more large-area aluminium base just can meet the requirements of radiating effect, be unfavorable for saving cost.If glass-fiber-plate, the lamp pearl is too little to the air area of dissipation, and heat-sinking capability is also undesirable.
The utility model content
The purpose of this utility model is to provide a kind of heat dispersion better LED wiring board, is adapted to other various types of LED light fixture PCB wiring boards such as aluminium base, glass-fiber-plate.
For achieving the above object, the utility model has adopted following technical scheme:
A kind of LED light fixture PCB wiring board is by the first heat radiation Copper Foil, the second heat radiation Copper Foil and control Copper Foil
Be packaged in the circuit board I shape or other shape copper foil structure.
Described the first heat radiation Copper Foil links together by control Copper Foil and the second heat radiation Copper Foil.
Described the second heat radiation Copper Foil can spray tin or can cover printing ink.
Described control Copper Foil cover printing ink be used for after the fusing of restriction tin cream not excessive, in the situation that do not worry excessively after the tin cream fusing can not cover printing ink.
Described wiring board is aluminium base, glass-fiber-plate or other any materials that can be used as wiring board.
The utility model is when the Design PCB wiring board, on the basis of the PCB of lamp pearl encapsulation, designing more Copper Foil is connected with original the first heat radiation Copper Foil of lamp pearl, Copper Foil can cover printing ink, also can not cover printing ink, can select the second heat radiation Copper Foil that designs is sprayed tin or do not spray tin according to using needs, the utility model design simultaneous adaptation is in the LED lamp pearl of various different encapsulation.
The utlity model has following beneficial effect:
The utility model adopts more Copper Foil to contact with air or other heat-conducting medium, and area of dissipation increases greatly, and radiating effect will improve greatly.Effectively reduced the junction temperature of chip and the temperature difference of lamp radiator, in the situation that the lamp radiator temperature is higher, the junction temperature of lamp pearl chip is still rationally in scope, thereby can reduce a large amount of heat sink materials; The raising of heat-sinking capability is conducive to dwindling of radiating element, thereby is beneficial to the saving cost; If the employing aluminium base can not only improve to the air heat-sinking capability, can also improve the lamp pearl to the heat-sinking capability of following aluminium sheet.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in further detail:
Fig. 1 is the utility model structural representation, and schematic diagram is take the 5630 LED lamp pearls that encapsulate as example;
Wherein, 1,2 is the second heat radiation Copper Foil, and 3,4 are the control Copper Foil, and 5 is original the first heat radiation Copper Foil.
Embodiment
As shown in Figure 1, the utility model is a kind of LED light fixture PCB wiring board, by the first heat radiation Copper Foil 5, the second heat radiation Copper Foil 1,2 and control Copper Foil 3,4 be designed in the circuit board the copper foil structure of I-shaped or other shape.Described the first heat radiation Copper Foil 5 links together by control Copper Foil 3, the 4 and second heat radiation Copper Foil 1,2.Described the second heat radiation Copper Foil 1,2 can expose or spray tin or can cover printing ink.Described control Copper Foil 3,4 covers printing ink, in the situation that do not worry excessively after the tin cream fusing also can not cover printing ink.Described wiring board is aluminium base, glass-fiber-plate or other any materials that can be used as wiring board.
