Description

Light emitting diode road lamp of strong reflection

Technical field

The utility model relates to the street lamp that road uses, and particularly relates to a kind of light emitting diode road lamp of strong reflection, belongs to ligthing paraphernalia.

Background technology

Along with the development of cities and towns and road construction, various street lamps have been installed in both sides such as street and highways.Street lamp mainly be configured to be installed in lamp socket and light source (illuminator) on the lamp stand, at present in order to advocate energy-conservation energetically and the environmental protection needs, be extensive use of light emitting diode (LED) as light source, harmful substance such as led light source has long service life, good, the high efficiency low energy consumption of antidetonation, and is not mercurous.The LED that is applied on the street lamp is high-power bulb, and many bulbs are combined, thus its fixedly the lamp socket of bulb be the bigger porous Connection Block of volume, also need an electric appliance control box simultaneously.Light emitting diode road lamp comprises heat radiation matrix and control matrix, is equipped with bulb fixed head, bulb and reflector in the heat radiation matrix, and is connected translucent cover and fixed frame on the heat radiation matrix.The one, what existing reflector adopted be planar rectangular body or bowl-shape parabola, and its light is to radiate, and the increase meeting that radius throws light on along with distance weakens very soon, and therefore, prior art LED street lamp is particularly to the illuminance weak effect on ground.The 2nd, the LED that is used on the street lamp is high-power bulb, and many bulb illumination back generation heats are big, but now the LED bulb does not match with the heat radiation matrix, and it is insufficient to dispel the heat, and causes the heat savings, influences the service life of bulb.

Summary of the invention

The purpose of this utility model is in order to overcome the shortcoming of prior art, to provide a kind of suitable LED bulb heat radiation effective working environment, making the illumination efficiency height, long service life, heat radiation matrix handling ease, change of shape is many, and prevents the light emitting diode road lamp of strong reflection of matrix surface variable color.

The technical scheme of the utility model light emitting diode road lamp of strong reflection is: comprise heat radiation matrix and control matrix, the back side of described heat radiation matrix is shaped on fin, be equipped with bulb fixed head, bulb and reflection support in the heat radiation matrix, and be connected translucent cover and the fixed frame of heat radiation on the matrix, be shaped on uniform reflector element in the reflection support, on the control matrix lid is arranged, it is characterized in that described reflector element is the inside recess in center, be shaped on bulb through hole in the recess, two of recess is outside ladder inclined-plane, and the both sides of recess comprise the inclined-plane and face directly.

Light emitting diode road lamp of strong reflection of the present utility model, its described reflector element is the inside recess in center, two of recess is outside ladder inclined-plane, and the both sides of recess comprise the inclined-plane and face directly that ladder inclined-plane and inclined-plane form the multi-angle refraction with facing directly, compare with existing planar rectangular body or bowl-shape parabola, multi-angle intersection refraction light emission rate height is avoided the illumination blind area, and illumination is bright, the refract light distance is far away, the road pavement good illumination effect.

Light emitting diode road lamp of strong reflection of the present utility model, its described ladder are 3 grades-8 grades, multistage ladder multi-angle refraction.Its described reflection support can be made for the plastics of metal material or plating metal on surface film, and the plastic material cost is low.Its described heat radiation matrix and control matrix are allosome, and between is linked to each other by screw, adopt in the split manufacturing and process flexibly, and quality can guarantee that planform changes many, reaches designing requirement easily, improve the heat dispersion of the matrix that dispels the heat.Between its described translucent cover and the fixed frame silicon rubber loop is installed, sealing is reliable, and wind, rain piping and druming are not advanced.Its described bulb fixed head is an aluminium sheet, and the fixed head of aluminum sticks on the heat radiation matrix inwall, helps heat radiation.Its described fixed head and heat radiation can have between the matrix heat-conducting silicone grease layer or thermal conductive silicon glue-line mutually bonding, and are forced fixingly by screw, can unload after the heat-conducting silicone grease layer is bonding, can not unload after the thermal conductive silicon glue-line is bonding.Its described translucent cover is the safety glass of extra white, and transparency is good, reduces the loss of luminous flux when avoiding dazzle.Its described heat radiation matrix and fin surface scribble fluorine carbon lacquer anti-discoloration layer.Its described control matrix back side is shaped on short fin, and there is the anti-variable color dope layer of fluorine carbon lacquer on the surface of control matrix and the surface of short fin.Because street lamp is exposed to the sun by sunlight down in the open and erosion by wind and rain for a long time, makes the street lamp surface be easy to variable color, as blackening, and be easy to the long-pending dust of going up, scribble anti-variable color coating after, can keep the look that remains unchanged for a long period of time, few dust stratification dirt, and when rainy, come off easily, make surface clean, attractive in appearance.
