Abstract
The LED street lamp of forced heat radiation, form primarily of housing, power supply and LED light source, power supply and LED light source are arranged at enclosure interior, the LED light source back side arranges fin, housing comprises upper cover and lower cover, arrange wind inlet channel and exhaust air flue in lower housing portion, be installed into fan and ventilating fan respectively in wind inlet channel and exhaust air flue, the enclosure interior of LED light source bottom arranges a dividing plate.The utility model makes by air intake fan and ventilating fan that lamp housing is inner to be produced mandatory generation air with outside and flow, thus the heat on fin is rapidly to diffuses flow in air, substantially increases the radiating efficiency of LED street lamp.
Description
Technical field
The utility model relates to lighting control technique field, is specifically related to a kind of LED street lamp of forced heat radiation.
Background technology
LED(semiconductor light-emitting-diode) white light technology is since appearance, and achieve epoch-making technological progress at mankind's lighting field, 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 that though in recent years increase, 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 because the photoelectric conversion rate of LED only about 35%.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.
Summary of the invention
The utility model provides a kind of LED street lamp of forced heat radiation, to solve the problem of the radiating effect difference that prior art exists.
The utility model forms primarily of housing, power supply and LED light source, power supply and LED light source are arranged at enclosure interior, the LED light source back side arranges fin, housing comprises upper cover and lower cover, solving the technical scheme that its technical problem adopts is arrange wind inlet channel and exhaust air flue in lower housing portion, be installed into fan and ventilating fan respectively in wind inlet channel and exhaust air flue, the enclosure interior of LED light source bottom arranges a dividing plate.
The both sides of the upper cover of above-mentioned housing arrange some radiating grooves.
The lower cover of above-mentioned housing arranges a LED mounting groove.
Operation principle of the present utility model: when producing heat after LED light source energising, make lamp housing inside produce mandatory generation air with outside by air intake fan and ventilating fan to flow, the heat that LED light source and power supply produce is forced to take away along wind inlet channel and dividing plate side by cold air, distributing of the fin heat of continuous promotion LED light source, then by dividing plate opposite side and exhaust air flue, heat is taken out of, thus reach saving fin use amount problem.
The utility model makes by air intake fan and ventilating fan that lamp housing is inner to be produced mandatory generation air with outside and flow, thus the heat on fin is rapidly to diffuses flow in air, substantially increases the radiating efficiency of LED street lamp.

Fig. 5 is the structural representation of the utility model lower cover.
1 housing, 2 upper covers, 3 lower covers, 4 power supplys, 5 LED light sources, 6 wind inlet channels, 7 exhaust air flue, 8 air intake fans, 9 ventilating fans, 10 dividing plates, 11 radiating grooves, 12 LED mounting grooves in figure.
Detailed description of the invention
As Fig. 1, Fig. 2, Fig. 3, shown in Fig. 4 and Fig. 5, a kind of LED street lamp of forced heat radiation, primarily of housing 1, power supply 4 and LED light source 5 form, it is inner that power supply 4 and LED light source 5 are arranged at housing 1, LED light source 5 back side arranges fin, housing 1 comprises upper cover 2 and lower cover 3, the both sides of the upper cover 2 of housing 1 arrange some radiating grooves 11, the lower cover 3 of housing 1 arranges a LED mounting groove 12, wind inlet channel 6 and exhaust air flue 7 are set in housing 1 bottom, fan 8 and ventilating fan 9 is installed into respectively in wind inlet channel 6 and exhaust air flue 7, the enclosure interior of LED light source 5 bottom arranges a dividing plate 10.
Operation principle of the present utility model: when producing heat after LED light source energising, make lamp housing inside produce mandatory generation air with outside by air intake fan and ventilating fan to flow, the heat that LED light source and power supply produce is forced to take away along wind inlet channel and dividing plate side by cold air, distributing of the fin heat of continuous promotion LED light source, then by dividing plate opposite side and exhaust air flue, heat is taken out of, thus reach saving fin use amount problem.
