The utility model discloses a novel heat-dissipating structure of a semiconductor illuminating lamp (for example, LED streetlamps or LED tunnel lamps), comprising a plurality of heat-dissipating fins and an n-shaped heat-conducting pipe; one arm of the n-shaped heat-conducting pipe is welded below a circuit board of the lamp, and the other end thereof extends out of the circuit board; the plurality of heat-dissipating fins, corresponding to the two poles of an n-shaped opening end of the n-shaped heat-conducting pipe, are provided with inserting holes; and each heat-dissipating fin is penetrated and welded at the two poles of the n-shaped opening end of the n-shaped heat-conducting pipe. Compared with the prior art, the heat-dissipating fins, the circuit board and the n-shaped heat-conducting pipe are fixedly connected by a welding mode to lead the three parts to be well contacted, thus being capable of fully transferring the working heat of a semiconductor light source on the circuit board to the middle-upper parts of the all the heat-dissipating fins, achieving the function of timely heat dissipation of the heat-dissipating fins, reducing the optical attenuation of the semiconductor illuminating lamp and further prolonging the service life.
Description
Technical field
The utility model relates to the radiator structure of a kind of semiconductor (for example LED) lighting, the radiator structure of especially a kind of LED street lamp or LED Tunnel Lamp.
Background technology
Semiconductor lamp generally all contains semiconductor light sources, wiring board and substrate, semiconductor light sources is the linear array setting in the circuit board, wiring board is fixed on the substrate, the heat that semiconductor light sources is produced when luminous by substrate conducts step by step and radiation is dispersed in the external environment, however such radiating mode poor effect.The semiconductor lamp ubiquity is because of the bad problem that serious light decay influences lamp life that produces of dispelling the heat at present, people are in order to improve the radiating effect of semiconductor lamp, thereby prolong the service life of semiconductor lamp, usually on substrate, increase by a radiator structure, the radiator structure of semiconductor lamp comprises a substrate, several radiating fins and ∩ type heat pipe made of copper, some radiating fins are fixed on the below of substrate side by side, vertically be provided with short slot on each radiating fin, substrate be provided with radiating fin on the corresponding groove of short slot, the width of its groove and short slot is identical with the caliber of heat pipe, the groove bottom land is consistent with distance between heat pipe two arms to the distance of short slot bottom land, the length that the length of heat pipe two arms is arranged more than or equal to some radiating fins, heat pipe laterally is embedded in the space of substrate recess and the formation of each radiating fin short slot, the one arm is posted by the groove top of substrate, and another arm is to abut on the bottom land and cell wall of each radiating fin short slot.Adopt this radiator structure, because of heat pipe and substrate and radiating fin are to adopt the interlocking mode to be connected, the easy loose contact of heat pipe and radiating fin like this, the heat that produces in the time of can not be fully with substrate semiconductor-on-insulator light source works in time passes to radiating fin, thereby its radiating effect is still not ideal enough, thereby shortens the service life of semiconductor light sources.
The utility model content
The purpose of this utility model provides the radiator structure of the novel semi-conductor lighting that a kind of heat conduction is fast, thermal diffusivity is good.
The technical solution of the utility model is such: a kind of novel semi-conductor lighting radiator structure, comprise several radiating fins and ∩ type heat pipe, the quantity of above-mentioned ∩ type heat pipe is to be provided with corresponding to the number of the arrangement of the circuit board semiconductor-on-insulator light source of light fixture, and the length that the length of heat pipe two arms is arranged more than or equal to some radiating fins, one arm of above-mentioned ∩ type heat pipe is welded on the circuit board downside of light fixture, another arm stretches out outside the circuit board of light fixture, above-mentioned some radiating fins offer patchhole corresponding to openend the two poles of the earth of " ∩ " shape of above-mentioned ∩ type heat pipe, and each radiating fin interts and is welded on openend the two poles of the earth of " ∩ " shape of above-mentioned ∩ type heat pipe.
Described radiating fin is fan-shaped or trapezoidal.
Described radiating fin is provided with the hollow out position.
The aperture of described patchhole is slightly larger than or equals the caliber of heat pipe.
After adopting technique scheme, the radiator structure of a kind of semiconductor lamp of the present utility model, the copper heat pipe adopts welding manner to fixedly connected with radiating fin, compared with prior art, welding by heat pipe and radiating fin is fixed, make the contact of heat pipe and radiating fin good, thereby can fully the work calories of the semiconductor light sources on the circuit board be conducted to the middle and upper part of each radiating fin rapidly, reach the function of the timely heat loss through radiation of radiating fin, thereby the light decay that reduces semiconductor lamp increases the service life; Adopt fan-shaped radiating fin and width from broadening down, fan-shaped radiating fin is bigger than the area of dissipation of square radiating fin under the situation identical with the circuit board bonding area like this, and improves radiating effect.And hollow out (through hole) position is set on radiating fin, further promotes vertical convection current of air, thereby improved radiating effect.
