Abstract
The utility model discloses a high-power LED circuit board, which sequentially comprises an aluminum substrate, an epoxy resin layer and a conductive layer from the bottom to the top, the LED circuit board is further provided with a plurality of mounting holes, the mounting holes are respectively embedded with an LED unit, the pins of the LED units are welded on the conductive layer, and the lower surface of the aluminum substrate is provided with a plurality of heat dissipating fins arranged side by side. Compared with the prior art, by arranging the aluminum substrate with the heat dissipating fins on the bottom surface of the high-power LED circuit board, the heat dissipating area of the aluminum substrate is enlarged, thereby the heat emitted by the LED units can be timely and effectively dissipated to the outside.
Description
Technical field
The utility model relates to the wiring board technical field, is specifically related to a kind of great power LED wiring board.
Background technology
The LED wiring board is parts commonly used in the electric equipment products; When using the high-power LED unit, can produce bigger heat usually on the LED pedestal, these heats concentrate on LED pedestal and the wiring board main body; Can not in time be distributed to the external world, be influenced the normal use of LED unit and wiring board.
The utility model content
To the deficiency of prior art, the purpose of the utility model is intended to provide a kind of great power LED wiring board, and the heat that it can be in time, effectively produced the LED unit is distributed to the external world.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
The great power LED wiring board; Comprise aluminium base, epoxy resin layer, conductive layer from the bottom to top successively; This LED wiring board is provided with a plurality of installing holes; Be embedded with the LED unit in the installing hole respectively, the pin of LED unit is welded on the conductive layer, and the lower surface of aluminium base has a plurality of radiating fins that are arranged side by side.
The cross section of installing hole is square or is circular.
The beneficial effect of the utility model is:
Than prior art, the LED wiring board of the utility model has increased the area of dissipation of aluminium base through be provided with the aluminium base of radiating fin in its bottom surface, thereby can be in time, the heat that effectively the LED unit produced is distributed to the external world.
Description of drawings
Fig. 1 is the structural representation of the utility model great power LED wiring board.
Embodiment
Below, in conjunction with accompanying drawing and embodiment, the utility model done further describing:
As shown in Figure 1; Be a kind of great power LED wiring board of the utility model; It comprises aluminium base 1, epoxy resin layer 2, conductive layer 3 from the bottom to top successively, and this LED wiring board is provided with a plurality of installing holes, is embedded with LED unit 4 in the installing hole respectively; The pin of LED unit 4 is welded on the conductive layer 3, and the lower surface of aluminium base 1 has a plurality of radiating fins 11 that are arranged side by side.When 4 work of LED unit, the heat of its generation is passed to aluminium base 1 via its base, owing at the lower surface of aluminium base 1 a plurality of radiating fins 11 are set; Increase the area of dissipation of aluminium base 1, can the heat that LED unit 4 produces in time, effectively be distributed to the external world, simultaneously; Epoxy resin layer 2 has heat insulation usefulness; It separates conductive layer 3 and aluminium base 1, and the heat on the aluminium base 1 can not be passed to conductive layer 3, also just can not impact conductive layer 3.
The above-mentioned cross section that is used to put the installing hole of LED unit 4 is square or is circular.
For a person skilled in the art, can make other various corresponding changes and distortion, and these all changes and distortion should belong within the protection range of the utility model claim all according to the technical scheme and the design of above description.
