Description

A kind of Novel LED street lamp structure

Technical field

The utility model relates to LED street lamp application technical field, especially a kind of Novel LED street lamp structure.

Background technology

The maximum feature of illuminating LED is the function with directional transmissions light, because power-type LED is nearly all equipped with reflector, and the efficiency of this reflector is all apparently higher than the reflector efficiency of light fixture. In addition, when the light efficiency of LED detects, comprised the efficiency of self reflector. Adopt the roads light of LED should utilize as much as possible the characteristic of the directional transmissions light of LED, make each LED in roads light distinguish the regional that directly light directive is shone to road surface, recycle the auxiliary luminous intensity distribution of lamp reflector, realize the comprehensive luminous intensity distribution of quite reasonable roads light. The function that light fixture planted agent comprises three luminous intensity distributions could realize better. And just there is good once light-distribution function with LED itself reflector and that there is rational light beam output angle. Reflector in this type of light fixture, only, as three times auxiliary luminous intensity distribution means, ensures the better uniformity of road illumination.

There are many deficiencies in current shaft coupling, single led power is low. High-power in order to obtain, need multiple in parallel uses; The color showing under LED irradiates does not have incandescent lamp true; Because defect in the manufacturing process of white light LEDs own adds and the mismatch error of reflector or lens, easily cause " yellow circle " problem; If do not carry out secondary optical design, the irradiation of LED is relatively to concentrate, so must carry out secondary optical design, makes its surface of intensity distribution be bat shape. Compare low-power LED, the light decay of high-power LED street lamp will be well a lot. But low-power LED dissipation of heat is very little. And high-power LED is to have the heat radiation problem solving of having no idea, and after heating, brightness meeting obviously reduces, so power can not do the shortcomings such as large, therefore, proposes a kind of Novel LED street lamp structure for the problems referred to above.
