Abstract
The utility model relates to a streetlamp with a heat radiation function, which comprises a streetlamp rod and a lamp body that is fixed on the upper end of the streetlamp rod, wherein, the streetlamp rod is communicated with the interior of the lamp body; the bottom part of the streetlamp rod is provided with a plurality of fresh air inlets, and the lamp body is provided with air outlets. By adopting the structure property of the streetlamp and under the situation that no device is added, air flow is produced inside the lamp body, so that the heat that is produced by the light source is instantly brought out of the lamp body by the air flow, thereby better resolving the heat radiation problem of the light source. The streetlamp is not only applicable to the ordinary light source streetlamp, but also is particularly applicable to the streetlamp adopting large power LED for the illumination.
Description
Technical field
The utility model relates to a kind of street lamp, particularly relates to a kind of design feature of street lamp of utilizing own, and does not add any device and has increased the street lamp of heat sinking function.
Background technology
As the road lighting device, street lamp all has higher requirement for brightness of illumination, working environment etc., and general street lamp lampshade all is in airtight state fully, and uses reflection shield with collected light in lampshade, improves brightness of illumination.Because what street lamp used is the bigger light source of power, the heat of corresponding generation is also more, is difficult for distributing in airtight space, add the thermal-arrest effect of reflection shield, cause the temperature in the lampshade constantly to be climbed sharply, both influenced the service life of light source and electric elements, have certain danger again.
Particularly in recent years, the great power LED technical development is rapid, and the trend of promoting the use of led light source on street lamp is arranged.But, directly influenced the application of led light source on street lighting owing to never find the solution of an effective led light source heat dissipation problem.
The CN2750186Y patent provides a kind of street lamp of tool heat radiation function, be by fin or directly be fixed on the seat of honour, and at the fixing a plurality of radiating fins of the periphery at the seat of honour, to strengthen area of dissipation with LED, quicken heat radiation, reach the effect that heat that great power LED produces distributes outward by the seat of honour.
Yet in fact, the street lamp of said structure can not reach the purpose of quick heat radiating, and radiating effect is not very good, and particularly under summer high temperature weather, it is slower to dispel the heat, and radiating effect is poorer.Simultaneously, owing to outside lampshade, increased many heat dissipation metal fins, also increased the weight and volume of street lamp lampshade greatly.
Summary of the invention
The purpose of this utility model provides a kind of design feature of street lamp of utilizing own, and does not add any device, promptly has the street lamp of heat sinking function.
Street lamp of the present utility model comprises the lamp body of light pole and end fixed thereon, and light pole communicates with lamp body inside, is provided with several fresh air inlets in the light pole bottom, and lamp body is provided with air outlet.
Rainwater enters in the lamp body in order to prevent to rain, and the utility model design is arranged on the air outlet position below of lamp body.
The utility model utilizes the chimney principle, under the situation that does not increase any device, only up and down set out air port and fresh air inlet respectively in two ends, make that to run through in the street lamp be an air channel, thereby utilize gas pressure at street lamp, in street lamp, produce air-flow power, air flows in the air channel, in time takes the heat that light source produces out of lamp body, makes the interior operating temperature of lamp body remain on normal temperature substantially, guarantee the working environment of light source, solved heat dissipation problem better.The utility model not only is suitable for the street lamp of ordinary light source, is particularly suitable for adopting the street lamp of high-power LED illumination.

The specific embodiment
Embodiment 1
Present embodiment is the ordinary light source street lamp, and its structure comprises light pole 9 and lamp body 6 as shown in Figure 1.
Lamp body 6 is made up of top cover 8, panel 2, reflection shield 4, lampshade 3 and ordinary light source 7, reflection shield 4 is placed in the top cover 8 successively with lampshade 3, fixing with panel 2, light source 7 is installed in the space of being made up of reflection shield 4 and lampshade 3, and lamp body 6 is fixed on the light pole 9 by top cover 8.
Be provided with several fresh air inlets 1 in light pole 9 bottoms, the panel 2 of lamp body 6 is provided with air outlet 5, by in fresh air inlet, the light pole between space, lamp body internal head cover and reflection shield space to air outlet to run through be an air channel, in street lamp, produce air-flow power, air flows in the air channel, the heat that light source produces is in time taken out of outside the lamp body, made the interior operating temperature of lamp body remain on normal temperature substantially.
Embodiment 2
Present embodiment is the led light source street lamp, and its structure comprises light pole 9 and lamp body 6 as shown in Figure 2.
Lamp body 6 is made up of top cover 8, panel 2, reflection shield 4, lampshade 3 and led light source 7, and reflection shield 4 is placed in the top cover 8 successively with lampshade 3, and fixing with panel 2, led light source 7 is adjacent to and is installed on the reflection shield 4, and lamp body 6 is fixed on the light pole 9 by top cover 8.
Be provided with several fresh air inlets 1 in light pole 9 bottoms, the panel 2 of lamp body 6 is provided with air outlet 5, by in fresh air inlet, the light pole between space, lamp body internal head cover and reflection shield space to air outlet to run through be an air channel, in street lamp, produce air-flow power, air flows in the air channel, the heat that led light source produces is in time taken out of outside the lamp body, made the operating temperature of LED remain on normal temperature substantially.
