Abstract
The utility model discloses a radiating LED (Light-Emitting Diode) street lamp which comprises a lamp pole, a lamp holder, a lamp housing and a lamp body. One end of the lamp holder is fixedly arranged on the lamp pole; the other end of the lamp holder is fixedly arranged on the lamp housing; the lamp body comprises a radiating fin, a substrate and LED lamp beads; the substrate is of a convex circular arc shape; the LED lamp beads are uniformly arranged outside the circular arc surface of the substrate; the radiating fin is arranged inside the substrate; a mounting rack is fixedly arranged inside the lamp housing; the lamp body is fixedly arranged on the mounting rack; and by arranging the radiating fin inside the substrate of the lamp body and arranging the mounting rack inside the lamp housing to install the lamp body, a radiating space is formed between the lamp body and the lamp housing, so that heat generated by the lamp body in the using process can be dissipated into the air by the radiating fin through the radiating space and the heat dissipating effect is good.
Description
Technical field
The utility model relates to a kind of LED lighting technical field, is specifically related to the LED lamp that a kind of heat dispersion is good.
Background technology
LED lamp is regarded as 21 century lighting source because having the advantages such as environmental protection, energy-conservation, the life-span is long, replaces just gradually conventional light source and widely applies on various lightings.But, LED lamp is as all electronic devices, in the process of using or operating, all can produce heat energy and temperature rise phenomenon, and LED chip is when work, its light emission rate and the temperature relation that is inversely proportional to, temperature is higher, and light emission rate is lower, when temperature reaches LED chip and meets high serviceability temperature, LED lamp will damage.Temperature has direct impact to the life-span of LED, light decay, colour temperature skew, and therefore, the heat radiation of LED light fixture and heat conductive design are the keys that maintains lamp life, yet the radiating effect of existing LED lamp is all unsatisfactory.
Utility model content
For above-mentioned deficiency of the prior art, the LED lamp that a kind of good heat dissipation effect is provided of the present utility model.
To achieve these goals, the technical solution adopted in the utility model is as follows:
Heat dissipation LED road lamp, comprise lamp stand, lamp bracket, lamp housing and lamp body, one end of lamp bracket is fixedly mounted on lamp stand, the other end is fixedly mounted on lamp housing, described lamp body comprises fin, substrate and LED lamp pearl, described substrate is the circular arc of evagination, the uniform arc surface outside that is arranged on substrate of LED lamp pearl, and described fin is arranged on the inner side of substrate; Described lamp housing inner side is fixed with installing rack, and lamp body is fixedly mounted on installing rack.
Further, described substrate is copper base.
Further, described installing rack arranges along lamp housing inner circumferential, and the sidewall of installing rack is provided with netted air vent.
With respect to prior art, the utlity model has following beneficial effect:
1, in the substrate inner side of lamp body, fin is set, in the inner side of lamp housing, installing rack is set for lamp body is installed, make to form between lamp body and lamp housing a heat-dissipating space, the heat that lamp body in use produces can be by fin, through heat-dissipating space, be dispersed in air good heat dissipation effect.
2, substrate is copper base, has further strengthened radiating effect.
3, installing rack arranges along lamp housing inner circumferential, and net dress air vent is set on the sidewall of installing rack, when guaranteeing radiating effect, airborne dust is filtered, and prevents airborne contamination by dust fin.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Referring to Fig. 1: heat dissipation LED road lamp, comprise lamp stand 1, lamp bracket 2, lamp housing 3 and lamp body, one end of lamp bracket 2 is fixed on lamp stand 1, and the other end is provided with lamp housing 3.Lamp body comprises fin 5, substrate 6 and LED lamp pearl 7.The circular arc copper base that substrate 6 is evagination, LED lamp pearl 7 is uniform is arranged on the arc surface outside of substrate 6, substrate 6 is set to the circular arc of evagination, both expanded illuminating area, increase again the installed surface of LED lamp pearl 7, increased the installation quantity of LED lamp pearl 7, improved the luminous quantity of single street lamp.Fin 5 is arranged on the inner side of substrate 6, and fin 5 can be the circular arc adapting with substrate 6.In lamp housing 3 inner sides, be fixed with installing rack 4, lamp body is fixedly mounted on the lamp socket of installing rack 4, between the fin 5 of lamp body and lamp housing 3, forms a heat-dissipating space.Installing rack 4 arranges along lamp housing inner circumferential, is provided with netted air vent on the sidewall of installing rack 4, and air vent is inclined on inwall, and the height of one end that air vent communicates with air is less than the height of the one end communicating with heat-dissipating space.
By installing rack being set in lamp housing inner side, lamp body is arranged on the lamp socket of installing rack, makes to form between lamp body and lamp housing a heat-dissipating space, and the heat that lamp body in use produces can be by fin, through heat-dissipating space, distribute.Installing rack is arranged along lamp housing inner circumferential, netted air vent is set on the sidewall of installing rack, can filter the air entering in heat-dissipating space, prevent the fin on airborne contamination by dust lamp body, affect radiating effect.
Finally it should be noted that, above embodiment is only in order to the technical solution of the utility model to be described but not restriction technologies scheme, although applicant has been described in detail the present invention with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, those are modified or are equal to replacement technical scheme of the present invention, and do not depart from aim and the scope of the technical program, all should be encompassed in the middle of claim scope of the present invention.
