Abstract
The LED street lamp of segmentation heat radiation, form primarily of lamp body, several light source carrier, several lens modules and constant-current driving power supply, lamp body comprises drive end bearing bracket, frame and rear end cap, light source carrier is fixed on frame, lens module is arranged in light source carrier, the constant-current driving power supply of powering to its work is arranged in the cavity of the frame of both sides, light source carrier and lens module are interconnected to constitute a luminescence unit, arrange air flow passage between every two luminescence units, all luminescence units are all parallel to be fixed on the frame of both sides.The heat conduction that LED can produce by the utility model is on radiating fin, namely air flow passage between two luminescence units can form the continual air flow pattern that hot-air rises, cold air supplements, thus the heat on lamp body fin is rapidly to diffuses flow in air, substantially increase the radiating efficiency of LED street lamp.
Description
Technical field
The utility model relates to technical field of lighting fixtures, is specifically related to the LED street lamp of a kind of segmentation heat radiation.
Background technology
LED (semiconductor light-emitting-diode) white light technology, since appearance, has achieved epoch-making technological progress at mankind's lighting field, and its range of application is more and more wider, achieves economic benefit and the social benefit of significant energy-saving and emission-reduction.Growing along with power-type LED demand, its on radiator structure also in the urgent need to further optimization, to meet the corresponding demand of LED technology progress.
High-power LED street lamp requires structurally good heat dissipation effect, is because the photoelectric conversion rate of LED only about 35%, though in recent years increase, but also limited, all the other are then converted to electric heating, form higher junction temperature, so that cause the light decay of LED, and then shorten its life-span.The form of heat radiation comprises hot conduction, hot flowing and radiation of heat, current, and LED street lamp mostly lays particular emphasis on the conduction of heat in heat dissipation technology design, to strengthen physical quantity and to expand the specific area of dispelling the heat in design.When LED works by this heat conduction structure produce thermal energy conduction to radiator after, natural diffuseness can only be leaned on to be distributed in air slowly by heat energy, and radiating effect is not very good.The further raising of current LED industry active demand heat dissipation technology, to reduce junction temperature, reduces light decay.
Utility model content
The utility model provides the LED street lamp of a kind of segmentation heat radiation, to solve the problem of the radiating effect difference that prior art exists.
The utility model is primarily of lamp body, several light source carrier, several lens modules and constant-current driving power supply composition, solving the technical scheme that its technical problem adopts is that lamp body comprises drive end bearing bracket, frame and rear end cap, the two ends of frame are interconnected with drive end bearing bracket and rear end cap respectively, lamp body top arranges dividing plate, light source carrier is fixed on frame, lens module is arranged in light source carrier, the constant-current driving power supply of powering to its work is arranged in the cavity of the frame of both sides, light source carrier and lens module are interconnected to constitute a luminescence unit, between every two luminescence units, air flow passage is set, all luminescence units are all parallel to be fixed on the frame of both sides, rear end cap is arranged lamp stand installing hole to insert arm when lamp stand is installed.
Operation principle of the present utility model: the radiator structure adopting heat flow feature, the entirety as installed surface that LED tradition is continued to use is divided and is cut to N section, the luminescence unit that every section of installation one group of LED module and corresponding secondary light-distribution lens module are formed, the passage that certain distance flows as air is reserved between every two sections, when LED works, after the light source carrier that its heat conduction produced dispels the heat to segmentation, air flow passage between two luminescence units can produce the effect of natural flow, heat in light source carrier is upwards pulled diffusion, the heat radiation of whole lamp is made to reach the effect of 1+1 (i.e. heat transfer+heat flow), the further heat radiation improving LED street lamp.
The heat conduction that LED can produce by the utility model is on radiating fin, namely air flow passage between two luminescence units can form the continual air flow pattern that hot-air rises, cold air supplements, thus the heat on lamp body fin is rapidly to diffuses flow in air, substantially increase the radiating efficiency of LED street lamp.

1 drive end bearing bracket, 2 frames, 3 light source carrier, 4 lens modules, 5 constant-current driving power supplies, 6 rear end caps, 7 lamp stand installing holes, 8 dividing plates, 9 air flow passage in figure.
Detailed description of the invention
As Fig. 1, shown in Fig. 2 and Fig. 3, a kind of LED street lamp of segmentation heat radiation, primarily of lamp body, several light source carrier 3, several lens modules 4 and constant-current driving power supply 5 form, lamp body comprises drive end bearing bracket 1, frame 2 and rear end cap 6, the two ends of frame 2 are interconnected with drive end bearing bracket 1 and rear end cap 6 respectively, lamp body top arranges dividing plate 8, light source carrier 3 is fixed on frame 2, lens module 4 is arranged in light source carrier 3, the constant-current driving power supply 5 of powering to its work is arranged in the cavity of frame 2 of both sides, light source carrier 3 and lens module 4 are interconnected to constitute a luminescence unit, between every two luminescence units, air flow passage 9 is set, all luminescence units are all parallel to be fixed on the frame 2 of both sides, rear end cap 6 is arranged lamp stand installing hole 7 to insert arm when lamp stand is installed.
Operation principle of the present utility model: when LED works, after the light source carrier 3 that its heat conduction produced dispels the heat to segmentation, air flow passage 9 between two luminescence units can produce the effect of natural flow, heat in light source carrier 3 is upwards pulled diffusion, make the heat radiation of whole lamp reach the effect of 1+1 (i.e. heat transfer+heat flow), improve the heat radiation of LED street lamp further.
