Abstract
The utility model provides an LED street lamp comprising a light distribution surface, a radiating fin arranged at the back surface of the light distribution surface, and a driving box arranged outside the radiating fin. The LED street lamp adopts a curved-surface-shaped light distribution surface so as to lead the overall height of the lamp to be lowered down and the overall width to be increased, therefore, the driving box can be externally arranged above the radiating fin, thus carrying out direct convection with air, conducting better radiation by means of the radiating fin, reducing the generation of steams, and prolonging the service life of the driving box; furthermore, the driving box is externally arranged, so that the driving box can be maintained by only needing to be detached, and the maintenance time and cost are reduced.
Description
Technical field
The utility model relates to a kind of LED street lamp that has improved.
Background technology
Power consumption is higher, luminosity is not enough for traditional street lamp (for example incandescent lamp), cause electric cost very high and be unfavorable for environmental protection, and the brightness of illumination of road pavement is also not enough, therefore, the LED street lamp progressively begins to replace traditional street lamp with the trend that has a bit become technical development of its high brightness, low-power consumption.Because LED street lamp luminous efficiency is very high, luminous intensity is big, therefore begun to popularize to use in many big cities.Yet high-luminous-efficiency and high brightness have inevitably brought the heat dissipation problem of LED street lamp itself, at high brightness, for a long time under the user mode, if can not dispel the heat to the LED street lamp, then the life-span of LED can be had a strong impact on, gently then cause LED to burn, serious also can initiation fire, therefore, existing LED street lamp etc. all adopts radiator that LED lamp pearl is dispelled the heat, yet, because existing LED street lamp adopts semicircle luminous intensity distribution face mostly, be subjected to the influence of height, drive box (drive circuit of built-in driving LED lamp pearl) operated by rotary motion in the side of fin, comprise many components, can constantly produce heat in the course of the work owing to drive in the box, return to outdoor temperature after quitting work again, therefore, if the radiating effect of drive circuit is bad, can influence the job stability of LED street lamp.And, in temperature changing process, drive in the box and can produce a small amount of water vapor, therefore component is easy to because of making moist and aging breaking down to street lamp can not be worked, but existing LED street lamp all adopts the built-in mode of closing that drives, in case the driving box breaks down and just whole LED street lamp must be taken off, on production line, light fixture to be taken apart fully just and can be keeped in repair, maintenance time is long and maintenance cost is very high.
The utility model content
The purpose of this utility model provides a kind of LED street lamp, is intended to solve the not good defective of drive circuit radiating effect of the LED street lamp that exists in the prior art.
The driving box that the LED street lamp that the utility model provides comprises a luminous intensity distribution face, is arranged at the fin at the luminous intensity distribution face back side and is installed on the fin outside.
More specifically, described luminous intensity distribution face is a curved surface shaped luminous intensity distribution face.
More specifically, described curved surface shaped luminous intensity distribution face is a waveform luminous intensity distribution face.
More specifically, described driving box is fixed on the fin by the gear mode.
More specifically, in the formed inner space of described luminous intensity distribution face a plurality of LED lamp pearls are set.
The LED street lamp that the utility model provides adopts curved surface shaped luminous intensity distribution face, make the whole height step-down and the integral width of light fixture strengthen, driving box like this can be external above fin, directly and cross-ventilation, better dispel the heat, reduce the generation of steam by fin, prolong the service life that drives, and, when maintenance drives box, only the driving box need be changed and get final product minimizing maintenance time and cost owing to the driving box is external.
Description of drawings
Fig. 1 is the driving box mounting structure schematic diagram of the utility model LED street lamp;
Fig. 2 is that the driving box of the utility model LED street lamp is installed schematic perspective view.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
In conjunction with referring to shown in Fig. 1, Fig. 2, the LED lamp post structure that the utility model preferred embodiment provides comprises curved surface shaped luminous intensity distribution face 10 and is arranged on a plurality of fin 11 at curved surface shaped luminous intensity distribution face 10 backs that the mode of installing by gear on the fin 11 is installed and driven box 12.The utility model at first changes the shape of luminous intensity distribution face, change original semicircle luminous intensity distribution face into curved surface shaped luminous intensity distribution face 10, the waveform luminous intensity distribution face 10 shown in Fig. 1 for example, this waveform luminous intensity distribution face 10 makes reflective surface area have greatly increased (waveform luminous intensity distribution face is provided with LED lamp pearl in the 10 formed inner spaces), therefore under equal even better reflecting effect, the whole height step-down of light fixture, integral width strengthens.The step-down of light fixture whole height makes that driving box 12 has enough spaces to be placed on fin 11 outsides, on the one hand can be so that drive the direct and cross-ventilation of box, and better dispel the heat by fin 11, reduce the generation of steam, prolonging the service life that drives, on the other hand, is external owing to drive box 12, when maintenance drives box 12, only driving box 12 need be changed and get final product minimizing maintenance time and cost.
The above only is preferred embodiment of the present utility model, and in order to restriction the utility model, for example curved surface shaped luminous intensity distribution face not only is not confined to the waveform shown in Fig. 1, also can be that other are fit to install the shape that drives box; The fixed form that drives box 12 and fin 11 also is not limited to the gear fixed form, also can be other easy-to-dismount fixed forms.All any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
