Abstract
The utility model discloses an LED straight guide aluminium-based circuit board. The LED straight guide aluminium-based circuit board comprises an aluminium-based plate on the bottom layer, a circuit layer on the top layer and an insulating layer on the middle layer, wherein a plurality of LED chips are arranged on the circuit layer, a plurality of bosses which protrude upwards and penetrate through the insulating layer are arranged on the aluminium-based plate, the quantity of bosses is the same as that of LED chips, and the top face of each of bosses contacts with the bottom face of each of LED chips. The LED straight guide aluminium-based circuit board is good in heat dissipation effect and long in service life.
Description
Technical field
The utility model relates to a kind of LED and directly leads aluminum base circuit board.
Background technology
Aluminum substrate structure commonly used is: top layer is circuit layer, and the intermediate layer is thermal insulation layer, and bottom is aluminium base heat dissipating layer.In the conventional usage of LED industry for single LEDs is welded on the aluminum-based circuit board, because the conduction of the heat of insulating barrier is poorer than metal, so the quality of the capacity of heat transmission of insulating barrier has directly affected the life-span of LED light fixture, the heat radiation of LED is to affect one of the key factor in LED life-span, every aluminium base manufacturer is owing to the aluminium-base plate insulating layer capacity of heat transmission of technology or the production of other reason is uneven, the aluminium base conductive coefficient of existing market has 1.0W/M.K, 2.0W/M.K, 3.0W/M.K. conductive coefficient is more expensive just higher, the height of insulating barrier conductive coefficient has just become the heat conducting function essential condition of aluminium base.
Metal heat-conducting all is good material, also can satisfy the LED radiating requirements of general power fully, but the too low transmission that just hinders the LED heat of insulating barrier heat conduction system causes occurring in the market the serious quality problem of optical attenuation of the LED light fixture of some relatively high powers.
The utility model content
Technical problem to be solved in the utility model provides a kind of LED and directly leads aluminum base circuit board, and this LED directly leads aluminum base circuit board good heat dissipation effect, long service life.
The technical solution of utility model is as follows:
A kind of LED directly leads aluminum base circuit board, comprise bottom aluminium base, top layer line layer and be positioned at the insulating barrier in intermediate layer; Be provided with the plurality of LEDs chip at line layer, aluminium base is provided with a plurality of boss that raise up and pass insulating barrier; The quantity of boss is identical with the quantity of led chip, and the end face of each boss contacts with the bottom surface of a LEDs chip.
Beneficial effect:
LED of the present utility model directly leads aluminum base circuit board, design by the boss on the aluminium base, so that the led chip heat dissipation region is direct and radiation aluminium basic unit close contact spreads out of heat fast, conductive coefficient can reach 200W/M.K, thereby radiating effect is splendid, can effectively prolong the useful life of led chip.
Description of drawings
Fig. 1 is the general structure schematic diagram (cross section view) that LED of the present utility model directly leads aluminum base circuit board.
Label declaration: 1-LED chip, 2-line layer, 3-insulating barrier, 4-aluminium base, 5-boss.
Embodiment
