Street lamp with high-power light-emitting diode (LED) single polycrystalline chip die set

Abstract

The invention relates to a street lamp with a high-power light-emitting diode (LED) single polycrystalline chip die set, which comprises a shell body formed by a back shell and a surface shell, a light field photomask, a high-power LED single polycrystalline chip die set, light scattering lenses, and a heat radiating device provided with an arc-shaped heat radiator and a superconductive heat pipe, wherein the surface shell is provided with a first window; the light field photomask is arranged in the first window of the shell body; the light scattering lenses are solid core lenses taking the flat bottom surface as the light incidence surface and are arranged in the bottom mouth in the light field photomask; the flat bottom surfaces of the light scattering lenses tightly contacts with the silica gel on the surface of the high-power LED single polycrystalline chip die set without gap so as to form a batwing rectangular light field distribution curve flux by utilizing a primary light source; and the heating radiating device is arranged on the hogged part of the back shell. The high-power LED single polycrystalline chip die set is taken as a light source and is matched with the light field photomask and the single light scattering lens to reach the requirement of the batwing rectangular light field distribution curve flux street lamp by using the primary light source; the brightness uniformity is enhanced, and the lighting effect is good; the shell body is prepared by adopting ultraviolet-resistance aging-resistance reinforced and toughened plastics; the weight is greatly reduced; and the street lamp is conveniently installed and safely used.

Description

technical field [0001] The invention relates to a street lamp for lighting, in particular to a high-power LED single polycrystalline chip module street lamp for lighting. Background technique [0002] Traditional road lighting often uses high-pressure sodium lamps, which have the disadvantages of short life and high energy consumption. Therefore, LED street lamps for solid-state lighting have been developed. The existing high-power LED street lamps have serious heat dissipation problems. Unable to resolve. Especially high-power LED single polycrystalline chip modules are more serious, and there is also the problem of light distribution curve, that is, the rectangular light field of the batwing, which cannot be solved by the primary light source. Only the tertiary light source of the reflector can be slightly improved. Therefore, its light efficiency is seriously reduced. [0003] Although there are so-called LED street lighting demonstration roads at present, they cannot b...

Problems solved by technology

However, the LED street lamp composed of multiple LED arrays does not concentrate light well. Even if the light is collected by a condenser reflector, the luminous efficiency will be reduced by about 20%.

[0004] At present, there is no relevant literature disclosure of high-power LED street lamps with a primary light source design scheme, especially high-power LED single polycrystalline chip module street lamps.
