Description
Technical field
The utility model relates to a kind of LED, particularly, relates to a kind of efficient heat radiating LED street lamp.
Background technology
LED street lamp replaces conventional light source just gradually widely apply on traffic lighting because having the advantages such as environmental protection, energy-conservation, life-span be long.LED street lamp is as all electronic devices simultaneously, heat energy and temperature rise phenomenon all can be produced in the process used or operate, and LED chip operationally, its light emission rate and temperature are inversely, namely temperature is higher, light emission rate is lower, and when temperature reaches LED chip chance operation at high temperature, LED lamp will damage.Temperature has direct impact to life-span of LED, light decay, color temperature shift, and therefore, the heat radiation of LED light fixture and heat conductive design are the keys maintaining lamp life, but the radiating effect of existing LED lamp is all unsatisfactory.The bad street lamp that easily causes that dispels the heat damages, and installs to change to bother very much due to street lamp, improves street lamp bulk life time extremely important.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, provides the high-efficiency heat radiating LED street lamp that a kind of perfect heat-dissipating, radiating efficiency are high, simple and practical.
The technical scheme in the invention for solving the above technical problem is: a kind of efficient heat radiating LED street lamp, comprise street lamp casing, substrate, radiator, heat-conducting plate, LED and Unpowered ventilation device, LED is uniform to be arranged on below substrate, described heat-conducting plate is arranged on thereon, described heat-conducting plate is corresponding with LED to be arranged, radiator is arranged on heat-conducting plate, and Unpowered ventilation device is arranged on street lamp casing top.
Further, in order to effectively in time heat radiation, described radiator is horn-like structure, uniformly on horn mouth wall is provided with heat radiation graphite flake.
Further, described heat radiation graphite flake thickness is 1.5mm, can timely quick heat radiating.
Further, the horn-like structure of described radiator is copper material, is convenient to heat conduction.
Further, uniformly on the horn mouth wall of described radiator be provided with through hole, be convenient to heat radiation.
Further, in order to increase the space in lamp housing, effectively discharge internal heat, and can increase Street Light Illumination area, substrate is the arc shape of evagination.
Further, in order to increase air flowing in housing, described substrate is network structure.
To sum up, the beneficial effects of the utility model are:
1, an efficient heat radiating LED street lamp, radiator adopts copper horn mouth and heat radiation graphite flake complicated utilization, and heat radiation structure design is reasonable, takes full advantage of space, increases area of dissipation, improve radiating efficiency.
2, Unpowered ventilation device is set on outer protecting shell, makes lamp housing inner air and outer air exchange effectively and timely, avoid that internal temperature is too high affects LED service life.
3, employing arc shape substrate can increase the space in lamp housing, effectively can discharge internal heat, and can increase Street Light Illumination area.
