Description
One, technical field
The present invention relates to lighting technical field, relate to a kind of LED road illuminating lamp or rather.
Two, background technology
At present, the street lamp used of city illumination mostly is high-pressure mercury lamp greatly.Though high-pressure mercury lamp improves a lot at more traditional incandescent lamps in aspect such as luminous efficiency, power, service lifes, but because the glow color of such light fixture is yellow, and the colour temperature of sodium vapor lamp and video picture index are all lower: the video picture index is 20～25 (sunshine is 100), its colour rendering is also poor, sees all distortions of many things evening under light.Sodium vapor lamp is normally luminous from being opened in addition, needs five to ten minutes preheating time, and traditional sodium vapor lamp is to produce gas and luminous by high voltage, and this has just determined that the light source power consumption of high-pressure mercury lamp is bigger, and service life is short.
Along with the development of LED technology with ripe, compare with conventional light source, have that luminous efficiency height, power consumption are little, long service life, security reliability is high and advantage such as more energy-conservation, and make LED obtain using widely at lighting field.But in the existing LED street lamp, adopt white light LEDs mostly as light emitting source, because of its lighting angle little, on illuminating area, the center brightness height, edge brightness is low, can produce the zebra effect on road, uniformity of illuminance is poor, and utilize lens to carry out the secondary optics design, light utilization efficiency is low, whole lamp luminous intensity deficiency, more, can't satisfy modern road Lighting Design requirement because LED street lamp colour rendering is relatively poor.
Three, summary of the invention
It is low to the objective of the invention is to solve the road-light light-source utilization rate that exists in the prior art, the luminous intensity deficiency, and defective such as colour rendering is relatively poor provides a kind of high brightness, high-color rendering, the high-capacity LED road illuminating lamp of high evenness.The LED street lamp of prior art all adopts white light LEDs as light source, because the principle of luminosity of white light LEDs is to excite yellow fluorescent powder to realize by the blue light wafer, its red primary composition is less, causes the colour rendering of street lamp relatively poor thus.If on the white light chromatogram basis that white light LEDs sends, suitably increase the red primary composition and replenish, will improve the colour rendering of LED street lamp effectively.
The present invention can realize by following technology:
A kind of LED road illuminating lamp, mainly comprise radiating shell, high-power LED light source module, reflection shield, diffuser, constant current switch power source drive device, it is characterized in that: radiating shell has five installation base surfaces, its integral body protrudes out setting towards the LED light direction, five installation base surfaces are symmetric arrays with respect to the installation base surface of centre, in the middle of one installation base surface and be positioned at described in the middle of the relative separately inclined-plane installation base surface of two-stage of installation base surface both sides.Described inclined-plane installation base surface comprises two first order inclined-plane installation base surfaces and inclined-plane, two second level installation base surface, angle between two described first order inclined-plane installation base surfaces and the described middle installation base surface is α, angle between two described second level inclined-plane installation base surfaces and the described middle installation base surface is β, 25 °≤α≤35 °, 55 °≤β≤65 °, one row's high-power LED light source module is installed on each installation base surface, high-power LED light source module adularescent led light source module, two kinds of red LED light source modules, can be alternately or be arranged on side by side on five installation base surfaces, in vain, the brightness ratio of red two kinds of led light source modules is 10: 1, in the white light chromatogram, increase the composition of red primary with this, thereby improve the colour rendering of LED street lamp.White LED light source module, red LED light source module are driven by the constant current switch power source drive device by the mode of being connected in series.
Described high-power LED light source module is made up of high-power LED light source and copper base, has printed circuit on the copper base, and high-power LED light source is welded on the printed circuit of copper base.
A reflection shield all is installed on the high-power LED light source module on the described installation base surface, reflection shield is installed on the default boss of lamp body, each installation base surface is installed the reflection shield of different reflective angles, and the reflective angle of reflection shield is followed successively by: 50 °, 80 °, 60 °, 80 °, 50 °.By changing the size and the angle of reflection shield, the lighting angle of control LED street lamp makes the central area of illumination range and the brightness basically identical of fringe region.Both improve whole light according to intensity, promoted the uniformity of illuminance of whole lamp again.Described reflection shield can adopt ABS or other homogeneous materials to make, and adopts vacuum aluminum-coated or other technologies plate reflectorized material at the reflection shield inwall.
All there is an acrylic diffuser to be installed in above the radiating shell on the described installation base surface.
Described radiating shell is formed in one, and through being extruded to shape into shell section material, the back side is provided with some fin by aluminium.
The beneficial effects of the utility model are: radiating shell is provided with a plurality of shadow surfaces, adopt high-capacity LED as light source, dispose the reflection shield of suitable angle of reflection simultaneously, reduced the secondary light loss, improved the utilization rate of light source widely, make that range of exposures is not only big but also brightness is high, and light distribution is even, makes the road surface not have the zebra effect phenomenon.Since with the White LED light source be main light source basically, increased the red primary composition and replenished, improved the colour rendering of LED road illuminating lamp effectively, display color is bright-coloured, more near sunshine, can fully satisfy the requirement of modern road illumination standards.
