Abstract
The invention discloses a grid type LED road lamp reflector, which comprises a reflecting base, at edge of which positioning holes are provided. On the reflecting base, one or more reflective recesses are provided, each has one or more holes for LED light source; on the reflector, a reflective film is provided. The side guiding curve of the reflector is an elliptic curve. The guiding curve at front of the reflector is a hyperbolic curve or a line. The invention can guide well the light ray generated by LED light source, can basically concentrate the light for LED light source onto the extended direction of a road, therefore basically no light waste exists outside the road surface, and the illuminance changes evenly on the road surface, the invention can meet well the road illumination. In addition, by adjusting the side guiding curve depending upon height of the lamp rod can control the road width illuminated by the road lamp.
Description
Technical field
The present invention relates to a kind of grille type LED road lamp reflector, relate in particular to high-power, high brightness LED (LED) LED road lamp reflector as lighting source.The invention belongs to technical field of semiconductor illumination.
Background technology
In recent years, along with the continuous development of LED scientific research and the chip technology level of production constantly promote, the high-power LED encapsulation technology is ripe gradually, and the LED luminous efficiency is greatly improved, and its application is progressively widened.LED is the less semiconductor devices of a kind of appearance and size, have that size is little, the life-span is long, no mercury is nontoxic, no electromagnetic pollution, no harm ray, power requirement is low, luminous efficiency is high, initial drive characteristic is good, anti-vibration performance is high, repeatedly the power switch better tolerance, inflate, plurality of advantages such as sealing not.The light efficiency index of the bulk article of 1W white light LEDs has surpassed 100lm/W at present, and progress of science and technology makes LED very likely replace incandescent lamp, fluorescent lamp becomes solid light source of new generation.
LED mainly needs to handle well heat radiation and luminous intensity distribution two large problems when the light fixture as light source applications of new generation.The present invention mainly is the research of being done at the luminous intensity distribution problem.The formation of optical system all is basic light is done straightline propagation and reflection taken place and reflect at the interface place of two kinds of materials in homogeneous substance a principle in the light fixture.Existing LED road-light light-source adopts lens usually or does not use reflector, adopts lens that the effect of optically focused is arranged, and still the angle of lens is all smaller usually, and the uniformity of light intensity was difficult to control when the better still a lot of lens of the increase effect of light intensity were used together.Very even as not using reflector that light is distributed, but light intensity is very low, and part light can not get effective utilization, but can reduce the cost of light fixture.
Summary of the invention
The purpose of this invention is to provide a kind of grille type LED road lamp reflector, be used for the zone that light that the LED street lamp sends light source guided and reflexed to needs again, improve the illumination utilization rate of light fixture.
Grille type LED road lamp reflector comprises the reflection matrix, is provided with locating hole at the reflection matrix border, is provided with one or more reflection recess on the reflection matrix, and position, one or more led light sources hole is arranged in each groove, and reflector is provided with reflectance coating.
Described reflector side guiding curve is an elliptic curve.The positive guiding curve of reflector is hyperbola or straight line.
The present invention can well guide the light that led light source sends, can concentrate on the light of led light source substantially on the bearing of trend of road, outside the road road surface, do not have the light waste substantially, and the illumination change on the road surface is even, is well positioned to meet the road lighting requirement.Adjust the road width that side guiding curve can be controlled the street lamp irradiation according to pole height simultaneously.
This LED reflector result on trial shows that this product effectively combines the characteristics of luminescence of led light source, makes full use of the reflection of light principle, effectively improves the illuminating effect of light fixture; Rational in infrastructure, assembling, easy for installation is applicable to the reflective design of LED road lamp of various height, and application prospect is boundless.

Fig. 1 is the grille type LED road lamp reflector structural representation;
Fig. 2 is a single led light source reflecting part cutaway view;
Fig. 3 is a single led light source reflecting part front view;
Fig. 4 road lamp light distribution curve map;
Among the figure: reflection recess 1, position, led light source hole 2, locating hole 3, side guiding curve 4, positive guiding curve 5.
The specific embodiment
Grille type LED road lamp reflector comprises the reflection matrix, is provided with locating hole 3 at the reflection matrix border, is provided with one or more reflection recess 1 on the reflection matrix, and position, one or more led light sources hole 2 is arranged in each groove, and reflector is provided with reflectance coating.Described reflector side guiding curve 4 is an elliptic curve; The positive guiding curve 5 of reflector is hyperbola or straight line.
Grille type LED road lamp reflector is installed in the LED street lamp, adopts the mode of similar grid, the position, hole in the corresponding reflection recess of each led light source.The reflection recess surface-coated has reflectance coating, and preferred reflectance coating is chromium film, nickel chromium triangle film.This utility model mainly is to utilize reflection of light to make on the bearing of trend that is distributed in the road road surface that light can be average, and the light utilization efficiency height does not have tangible hot spot, improves the illuminating effect of light fixture.
The grille type LED road lamp reflector is for each led light source all designs an independent reflection recess, interconnects between the independent reflection recess, and the reflection recess of connection becomes a groove of " grid ".
The grille type LED road lamp reflector is that the light source at the LED street lamp carries out luminous intensity distribution, and purpose is in order to reach the light distribution effect shown in Fig. 4.
The grille type LED road lamp reflector can be according to the quantity of LED in the light fixture quantity of corresponding change independent reflectors, the side guiding curve in the independent reflectors can adjust accordingly according to the irradiation distance and the irradiated area of light fixture.
