Description
Technical field
The utility model relates to a kind of LED street lamp, especially relates to a kind of radiator of LED street lamp.
Background technology
Road lighting is the important component part of city illumination, and traditional street lamp often adopts, and high-pressure mercury lamp 360 degree of luminescences, the shortcoming that light loss is large causes the huge waste of the energy.Current, global environment is going from bad to worse, and each state is all at development clean energy resource.And along with the rapid growth of national economy, China's energy supply and demand contradiction is outstanding day by day, supply of electric power comes into existence the situation of critical shortage, and energy-conservation is institute's urgent problem.Therefore, development of new is efficient, energy-conservation, the life-span is long, colour rendering index is high, the LED street lamp of environmental protection is of great significance the energy-conservation tool of city illumination.
Road lighting and people's productive life closely related, along with the quickening of Urbanization in China, LED street lamp with directional lighting, the advantage such as power consumption is low, drive characteristic good, fast response time, shock resistance are high, long service life, environmental protection enter into gradually people the visual field, become the energy-conserving light source of new generation most in the world with alternative conventional light source advantage, therefore, LED street lamp will become the optimal selection of roadway illumination and energy saving transformation.
But because LED street lamp power is large, caloric value is also large, and existing radiator cannot carry out efficient transfer of heat, affects the life-span of LED street lamp chip.
Utility model content
The utility model devises a kind of radiator of LED street lamp, and its technical problem solved is because LED street lamp power is large, and caloric value is also large, and existing radiator cannot carry out efficient transfer of heat, affects the life-span of LED street lamp chip.
In order to solve the technical problem of above-mentioned existence, the utility model have employed following scheme:
A kind of radiator of LED street lamp, it is by (13) bottom fin, radiator top (14), the long sidewall of radiator first (15), the cuboid cavity structure of the long sidewall of radiator second (16) and two short sidewall compositions of radiator, multiple fin (11) is provided with in cuboid cavity structure, fin (11) two ends are separately fixed at (13) and radiator top (14) bottom fin, vertical ventilation passage (12) is formed between adjacent two fin (11), bottom fin, (13) have fan mounting holes, bottom fan is arranged in fan mounting holes, radiator top (14) is connected with luminescence unit (2) and has multiple air vent (141), the air vent (141) at radiator top (14) communicates with the air vent (23) on the circuit board (21) of luminescence unit (2), it is characterized in that: on the long sidewall of radiator first (15), also have fan mounting holes (151), sidewall fan is arranged in fan mounting holes (151), and multiple fin (11) have air vent corresponding to the long sidewall of radiator second (16) forms horizontal ventilation passage in the horizontal direction for sidewall fan, vertical ventilation passage (12) and the alternation of horizontal ventilation passage.
Further, described fin (11) forms multiple concaveconvex structure in the vertical direction to increase heat exchange area.
Further, sidewall fan and bottom fan realize being used alternatingly at both ends of power by lines in parallel.
The radiator of this LED street lamp has following beneficial effect:
(1) the utility model arranges vertical ventilation passage and horizontal ventilation passage in radiator, the heat conduction that LED chip is easily distributed by vertical ventilation passage is on fin, but because having a narrow range of temperature in vertical ventilation passage between hot-air and fin causes the heat exchange efficiency of fin and hot-air low, so by arranging horizontal ventilation passage, the cold air of outdoor relative low temperature is imported, and the hot-air after heat exchange is derived fast, thus substantially increase the heat exchange efficiency of fin, also improve the radiating efficiency of LED lamp.
(2) the utility model vertical ventilation passage and the alternation of horizontal ventilation passage, avoid two air channels mutually to disturb, cooperatively interact both guaranteeing cooperation simultaneously, vertical ventilation passage is by heat from LED chip heat exchange to fin place, and heat imports in the environment of relative low temperature from fin by horizontal ventilation passage.

Detailed description of the invention
Below in conjunction with Fig. 1, the utility model is described further:
As shown in Figure 1, a kind of radiator of LED street lamp, its by bottom fin 13, the cuboid cavity structure that forms of radiator top 14, the long sidewall of radiator first 15, the long sidewall of radiator second 16 and two short sidewalls of radiator, multiple fin 11 is provided with in cuboid cavity structure, fin 11 two ends to be separately fixed at bottom fin 13 and radiator top 14, vertical ventilation passage 12 is formed between adjacent two fin 11, bottom fin, 13 have fan mounting holes, and bottom fan is arranged in fan mounting holes; Radiator top 14 is connected with luminescence unit 2 and has multiple air vent 141, and the air vent 141 at radiator top 14 communicates with the air vent 23 on the circuit board 21 of luminescence unit 2.The long sidewall 15 of radiator first also has fan mounting holes 151, and sidewall fan is arranged in fan mounting holes 151, and multiple fin 11 have air vent corresponding to the long sidewall of radiator second 16 forms horizontal ventilation passage in the horizontal direction for sidewall fan; Vertical ventilation passage 12 and the alternation of horizontal ventilation passage.Fin 11 forms multiple concaveconvex structure in the vertical direction to increase heat exchange area.
