Abstract
The utility model discloses an LED road lighting lamp with a quadric surface optical reflection reflecting device, which comprises a luminescent diode LED, wherein the LED road lighting lamp is characterized in that the luminescent diode LED is matched with a reflecting device to form a light-emitting module, a plurality of light-emitting modules are arranged on a circuit board to form a lighting line unit, and a plurality of lighting line units are arranged on a heat dissipation base to form the LED road lighting lamp. Since the road lighting lamp uses the reflecting device of quadric surface optical reflection, light which is emitted by an LED light source can be fully and effectively collected, light can be reflected with an accurate angle through a quadric surface with high index of reflection, finally, a light spot which is similar to a rectangle and has high illumination evenness degree is formed on an illuminated road, the LED road lighting lamp has concise structure, high lamp efficiency and convenient installation, and a light intensity distribution curve of emergent light can satisfy the demands of road lighting lamps on luminosity and structures.
Description
Technical field
The utility model relates to a kind of road lighting lamp, and particularly a kind of LED road lighting lamp with quadratic surface optical reflection reflector belongs to technical field of lamps.
Background technology
The structure that the conventional light source road lamp generally adopts reflection to add transmission produces a circular speck on the road surface, the hot spot of homonymy street lamp spreads out the lighting requirement that reaches the road surface successively along the road.This typical luminous intensity distribution of conventional lamp exists some shortcomings: at first, single High-Pole Lamp obtains the bright dark circular light spot all around in center on the road surface, and promptly there is the inhomogeneities of vertical and horizontal in single hot spot brightness.Secondly, adjacent spots is arranged in order the whole illumination that forms the road surface, and the circular light spot joint inevitably produces the dark space, and under the prerequisite that does not improve cloth lamp density, " dark space " of hot spot junction is exactly to limit the bottleneck that the road luminance uniformity improves.For guaranteeing high uniformity of illuminance, the normal cloth lamp density that increases promptly overlaps adjacent spots, and the thing followed is the increase of power consumption, running in the opposite direction with energy-conservation aim. luminescent diode LED volume is little, does not exist conventional light source to block and light-absorbing problem; Its rising angle is little, only ray cast is arrived the road surface direction, does not exist heavenwards emission light to cause the problem of light pollution.LED just takes the first step in the application in road lighting field, and mostly existing LED street lamp is the plurality of LEDs simple arrangements is pieced together, need not quadric optical reflection, can not fully effectively utilize the emergent light flux of LED.
Summary of the invention
The purpose of this utility model is in order to overcome existing LED road lighting lamp point really, a kind of LED road lighting lamp with quadratic surface optical reflection reflector to be provided.
The technical solution of the utility model is: a kind of LED road lighting lamp with quadratic surface optical reflection reflector, comprise LED, be characterized in, by a LED match with a reflector assembling light emitting module, place by a plurality of light emitting modules to be assembled into an illumination column unit on the circuit board, place by multiple row illumination column unit to be combined into the LED road lighting lamp on the heat dissipation base.
Described reflector constitutes a rectangle optical collector by four reflectings surface, and each reflector shape of optical collector is an eccentricity less than 1 conic section.
The silver or the aluminium of inner four the reflecting surface vacuum plating high reflectances of described reflector, and on silverskin or aluminium film, add the diaphragm that plating prevents the metallic reflective coating oxidation.
Two reflecting surface bottoms of described reflector are equipped with the hole cooperation that is equipped with on two pins and the circuit board and are used for fixing reflector.
The beneficial effects of the utility model are: because the road lighting lamp reflector of quadratic surface optical reflection, the abundant light that sends of effective collection led light source, quadratic surface by high reflectance reflects away light with accurate angle, finally be similar to rectangle and the high hot spot of uniformity of illuminance being subjected to form on the road of photograph, the utility model is simple for structure, Luminaire efficiency is high, the curve of light distribution easy for installation, emergent ray satisfies road illuminating lamp in luminosity and structural requirement.

The specific embodiment
A kind of LED road lighting lamp with quadratic surface optical reflection reflector, by shown in Figure 4, comprise LED 2, be characterized in, by a LED 2 match with a reflector 1 assembling light emitting module, place by a plurality of light emitting modules to be assembled into LED lamp bar 7 on the circuit board 3, place by multiple row LED lamp bar 7 to be combined into the LED road lighting lamp on the heat dissipation base 4.Heat dissipation base 4 is the rectangular aluminum flat board.
Described reflector 1 constitutes a rectangle optical collector by four reflectings surface, and each reflector shape of optical collector is an eccentricity less than 1 conic section, sees Fig. 1, Fig. 3.
The silver or the aluminium of inner four the reflecting surface vacuum plating high reflectances of described reflector, and on silverskin or aluminium film, add the medium protection film that plating prevents the metallic reflective coating oxidation.
By Fig. 2 and shown in Figure 4, two reflecting surface bottoms of described reflector 1 are equipped with hole 6 cooperations that are equipped with on two pins 5 and the circuit board 3 and are used for fixing reflector.
Assembling process of the present utility model: a LED 2 is contained in the middle of the reflector 1, and multiple row LED lamp bar 7 usefulness screws are fixed on the heat dissipation base 4, reflector pin 5 is inserted the jack 6 that runs through LED lamp bar and heat dissipation base with fixing reflector.Cooperate circuit onboard led driver module, just can light LED and see final effect.Light emitting module quantity is required to decide by concrete road illumination.
