Description
Technical field
The utility model relates to a kind of LED lighting technical field, is specifically related to a kind of convection type heat dissipation LED road lamp.
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 maximum operation (service) 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, of the present utility modelly provide a kind of cross-ventilation that utilizes to carry out heat dissipation LED road lamp, good heat dissipation effect.
To achieve these goals, the technical solution adopted in the utility model is as follows:
Convection type heat dissipation LED road lamp, comprises lamp stand, lamp bracket, lamp housing and light source module, and one end of lamp bracket is fixedly mounted on lamp stand, and one end of described lamp housing is fixed on lamp bracket, and one end of light source module is fixed on lamp bracket, and the other end is fixed on the other end of lamp housing; Described light source module comprises substrate, LED lamp pearl, reflection shield and radiator, reflection shield is fixed on radiator, LED lamp pearl is arranged in reflection shield and is fixed on a side of substrate, one side of radiator and the opposite side of substrate are fixed, the opposite side of radiator is provided with a plurality of radiating fins, between adjacent two radiating fins, has wind passage.
Also comprise lamp bracket cover, described lamp housing is fixed on lamp bracket by lamp bracket cover, and described light source module is fixed on lamp bracket by lamp bracket cover.
With respect to prior art, the utlity model has following beneficial effect:
The utility model is fixed on one end of light source module on lamp bracket, the other end is fixed on the other end of lamp housing, make between radiator on light source module and lamp housing, to there is an airspace passing through for natural wind, form cross-ventilation, the heat timely light source module being produced is taken away, and reduces the junction temperature of LED lamp.Opposite side at radiator arranges a plurality of radiating fins, between adjacent two radiating fins, forms wind passage, has further strengthened the convection current of air, strengthens the heat radiation of radiator, extends the service life of LED street lamp.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation:
Fig. 2 is light source module 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 and Fig. 2: convection type heat dissipation LED road lamp, comprises lamp stand 1, lamp bracket 2, lamp housing 4, lamp bracket cover 3 and light source module.One end of lamp bracket 2 is fixedly mounted on lamp stand 1, and one end of lamp housing 4 is arranged on lamp bracket 2, and one end of light source module 5 is arranged on lamp bracket 2.In the present embodiment, lamp bracket cover is the tube-in-tube structure of hollow, and the other end of lamp bracket is set in the lamp bracket cover 3 of hollow structure, and lamp bracket 2 adopts screw to be fixedly connected with lamp bracket cover 3, and lamp housing 4 and light source module 5 all overlap 3 by lamp bracket and be arranged on lamp bracket 2.The other end of light source module 5 is fixed on the other end of lamp housing 4, just forms an airspace passing through for natural wind between light source module 5 and lamp housing, forms cross-ventilation, and the heat timely light source module being produced is taken away, and reduces the junction temperature of LED lamp.Light source module 5 comprises substrate 52, LED lamp pearl 53, reflection shield 54 and radiator 51, and reflection shield 54 is fixed on radiator 51, and LED lamp pearl 53 is arranged in reflection shield and is fixed on a side of substrate 52, and a side of radiator 51 and the opposite side of substrate 52 are fixed.In the present embodiment, a side and the substrate 52 of radiator 51 are fixed by heat-conducting glue, and this heat-conducting glue can be transmitted to the heat of substrate 52 on radiator 51 rapidly, then is dispersed in air by radiator 51.The opposite side of radiator 51 is provided with a plurality of radiating fins, between adjacent two radiating fins, has wind passage.Further strengthen the convection current of air, strengthened the heat radiation of radiator, extended the service life of LED street lamp.Light source module 5 can be set to two, and two light source modules can be one-body molded, also can divide body formedly, and between two light source modules, shape has angle, and in the present embodiment, the angle between two light source modules is at 110 °～160 °.
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.
