A kind of street lamp
Technical field
The utility model relates to lighting technical field, particularly relates to a kind of street lamp.
Background technology
LED (Light-emitting diode, light emitting diode) as a kind of luminescent device directly converting electrical energy into visible ray and radiant energy, be widely regarded as 21st century top quality green light source, it has a series of advantage, as low in operating voltage, power consumption is little, the life-span is long, and LED itself is all pollution-free, stable and reliable for performance with manufacturing process.Under the policy guide of energy-saving and emission-reduction, be widely used in lighting field.
Street lamp is a kind of light fixture providing illumination functions to road, the light fixture in general reference traffic lighting in the illumination zone of road surface.The infield of street lamp is common in the one-sided or both sides of road, for people occurred providing a great convenience at night.The illuminating lamp holder general position of existing street lamp is higher, make the illumination zone of light fixture larger like this, but just reduce the brightness of illumination of street lamp, and current LED lamp bead be all generally arrange a plane on aluminium base on, such radiating effect is poor, replacement cost is high, simultaneously road lamp energy-saving weak effect.Therefore, for solving the problem, spy provides a kind of new technical scheme.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of street lamp.
The utility model is achieved through the following technical solutions:
A kind of street lamp, comprise lamp stand, aluminium base, the side, upper end of described lamp stand is provided with heat abstractor, illuminating lamp holder, described illuminating lamp holder inside is provided with fixed head, and described fixed head is provided with some pieces of aluminium bases, and the upper end of described lamp stand is provided with the solar panel in horn-like structure, and opening direction upward, the bottom of described solar panel communicates with the passage of lamp stand inside, and the lower end of described lamp stand is provided with TRT and battery pack, and the side, middle lower end of described lamp stand is provided with assist illuminator.
As preferably, described aluminium base with between fixed head for plug-in type is connected.
As preferably, the subtended angle of described solar panel is at least 90 °.
As preferably, described battery pack and assist illuminator are electrically connected.
Compared with prior art, the beneficial effects of the utility model are: the utility model structure is simple, reasonable in design, the utility model will be by arranging multiple aluminium base, like this when wherein a certain piece of aluminium base is damaged, only need to change one piece that damages, do not need integral replacing, reduce replacement cost, also improve radiating effect simultaneously; By arranging assist illuminator, can improve the illuminating effect below street lamp like this, assist illuminator realizes power supply by street lamp self generating simultaneously, has energy-conservation effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1. lamp stand; 2. heat abstractor; 3. illuminating lamp holder; 4. fixed head; 5. aluminium base; 6. solar panel; 7. passage; 8. TRT; 9. battery pack; 10. assist illuminator.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, a kind of street lamp, comprise lamp stand 1, aluminium base 5, the side, upper end of described lamp stand 1 is provided with heat abstractor 2, illuminating lamp holder 3, described illuminating lamp holder 3 inside is provided with fixed head 4, described fixed head 4 is provided with some pieces of aluminium bases 5, and described aluminium base 5 with between fixed head 4 for plug-in type is connected, like this when wherein a certain piece of aluminium base 5 is damaged, only need to change one piece that damages, do not need integral replacing, reduce replacement cost, also improve radiating effect simultaneously, extend the service life of light fixture.
The upper end of described lamp stand 1 is provided with the solar panel 6 in horn-like structure, and opening direction upward, the subtended angle of described solar panel 6 is at least 90 °, affect little like this by solar illumination angle, generated energy is large, the bottom of described solar panel 6 communicates with the passage 7 of lamp stand 1 inside, the lower end of described lamp stand 1 is provided with TRT 8 and battery pack 9, during such work, solar panel 6 can convert solar energy into electrical energy, utilize the structure of solar panel 6 that rainwater-collecting is impacted TRT 8 through passage 7 simultaneously and realize generating, such two kinds of generation modes by power storage in battery pack 9, the side, middle lower end of described lamp stand 1 is provided with assist illuminator 10, described battery pack 9 is electrically connected with assist illuminator 10, wherein assist illuminator 10 realizes power supply by street lamp self generating, there is energy-conservation effect, the illuminating effect below street lamp can be improved so simultaneously.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
