Abstract
The utility model discloses an LED lamp wick with a dissipating structure used as a street lamp. The utility model comprises an LED board or a plurality of LED boards arranged according to required angles. The LED board comprises a plurality of columns and rows of LEDs which are distributed uniformly, an LED printed circuit board, a dissipating silica gel plate, and a metal dissipating plate. The dissipating silica gel plate is clipped and fixed between the LED printed circuit board and the metal dissipating plate. The LED printed circuit board, the dissipating silica gel plate, and the metal dissipating plate form an integral dissipating structure, which improves the dissipating area of LED, reduces the whole temperature of the lamp wick, slow the luminous decay of the LED, and prolongs the service life of LED to two times of that of the prior LED.
Description
One, technical field:
The utility model belongs to the LED wick that street lamp uses.
Two, background technology:
Though compare with the bulb of conventional road lamp, light emitting diode has that volume is light and handy, the life-span is long and can save plurality of advantages such as the energy in a large number, and its brightness ratio conventional lamp is inferior.Therefore, generally in use, the light emitting diode that can use a plurality of light emitting diodes to form usually is connected on the circuit board, and especially low power light emitting diode is to increase its luminosity.Light emitting diode is by the circuit board heat radiation, but because circuit board is with the made single plate body of metal, PCB or ceramic material mostly, therefore, it only has the both ends of the surface heat radiation.Along with increasing of light emitting diode quantity, its heat easily gathers and distributes and do not go out, and diode is with the rising of temperature, its electric current continues to increase, the increasing of electric current makes its temperature raise again, produces vicious circle, the light decay of diode is serious, finally can not use, so the service life of actual diode (LED) is shorter, its service time one is long, and luminous efficiency is also very low.Moreover electronic building bricks such as many electric capacity, resistance that can release heat are also arranged on the circuit board simultaneously, make the coefficient of heat conduction of this circuit board lower.In order to solve the light decay problem of LED light fixture, it is too impatient to wait to solve its heat dissipation problem.
Three, summary of the invention:
The utility model is exactly to solve now with the problems referred to above that exist in the technology, provide a kind of good heat dissipation effect, light decay slowly, the LED wick of the street lamp use of the band radiator structure of diode long service life.
For addressing the above problem, technical solution of the present utility model is: the LED wick that a kind of street lamp with radiator structure uses, and the led board that it is arranged by required angle by a led board or polylith is formed; Led board comprises LED, LED printed substrate, thermal grease sheet and the metal fin that equally distributed multiple row multirow is arranged; Thermal grease sheet clamping is between LED printed substrate and metal fin.
Above-mentioned described LED of the present utility model adopts four pin LED.
Three of the every row of above-mentioned described LED of the present utility model is one group, connects the back and connects a current-limiting resistance, is connected with another group again.Six of the every row of LED is one group, connects the back and connects a current-limiting resistance, is connected with another group again.
Because the utility model has added thermal grease sheet and metal fin in LED printed substrate back, LED printed substrate, thermal grease sheet and metal fin form an integral heat sink structure, increased the area of dissipation of LED, reduced the bulk temperature of wick, slowed down the light decay of LED, increase the service life of LED, be more than 2 times of original LED service life.And circuit board adopts printed substrate, has reduced manual solder joint, has guaranteed the reliability and stability of circuit.
