It is light source that traditional road lamp mainly adopts Metal halogen lamp, fluorescent lamp, and these light source volumes are big, and heat dispersion is poor.Along with the succeeding in developing of development of semiconductor and GaN great power LED, LED has obtained at aspects such as signal demonstration, back lightings using widely as semiconductor light sources in recent years.Be accompanied by the development with the high-power LED encapsulation technology of improving constantly of large power white light LED light efficiency, semiconductor light sources begins progressively to be applied to the white-light illuminating field.
Therefore led light source is applied to the concrete application that street lighting is the outdoor lighting of LED white light, but because led light source generates heat more seriously in the course of the work, heat radiation is the subject matter that the restriction led light source is used on street lamp.
Summary of the invention
For addressing the above problem, the utility model purpose is to provide a kind of LED street lamp with heat sinking function, to avoid causing the street lamp damage because of the led light source heating.
For achieving the above object, the utility model is mainly by the following technical solutions:
A kind of heat dissipation type light emitting diode (LED) street lamp, comprise street lamp top cover, street lamp cover and be arranged at LED road-light light-source between the two, described street lamp top cover is provided with auxiliary heat dissipation plate and many heat conduction reinforcements, and described heat conduction reinforcement one end is positioned at street lamp top cover upper end, and an end is positioned at street lamp top cover lower end.
Connect by street lamp upper and lower covers clasp between described street lamp top cover and the street lamp cover.
Described LED road-light light-source arranged outside has the led light source reflector.
Also be provided with a street lamp upper and lower covers support bar between described street lamp top cover and the street lamp cover.
Described street lamp cover bottom is provided with the street lamp post fixing hole.
Compared with prior art, the street lamp top cover that the utility model is installed led light source is provided with many heat conduction reinforcements and an auxiliary heat dissipation plate, strengthening the heat radiation of led light source, thereby has effectively guaranteed the operate as normal of led light source.
