Abstract
The utility model relates to a light-emitting diode street lamp which utilizes red, green and blue light-emitting diodes to synthesizes white light and comprises a lamp shade, a lamp body, a heating body, ground glass and a constant-current source. The utility model is characterized in that a light-emitting diode lamp panel is arranged in the lamp body, and the red, green and blue light-emitting diodes are welded on the light-emitting diode lamp panel and are driven by the constant-current after being connected in series and parallel respectively. The red, green and blue light-emitting diodes on the light-emitting diode lamp panel are evenly distributed, the brightness proportion of the red, green and glue light-emitting diodes is 2-4:5-7:0.5-2, and the irradiation light shapes of the red, green and glue light-emitting diodes are elliptical. The light-emitting diode lamp panel is coated with paste-shape thermal silicon grease and flexible thermal silica gel slices which are connected with the heating body, and the lamp shade is provided with the ground glass. The light-emitting diode street lamp has the advantages that low power superbright red, green and blue light-emitting diodes are utilized to synthesize white light or warm white light which is used as the light source of the street lamp, the lifetime of the street lamp is much longer than the lifetime of a street lamp whose light source is formed by white light-emitting diodes, moreover, the luminous efficiency is high, compared with the light source formed by white light-emitting diodes, the luminous intensity is increased by 1.5-3 times under the same power and same conditions, the lamp street has high color rendering, the displaying colors are brilliant, which are much close to sunlight.
Description
Technical field
The utility model relates to a kind of LED street lamp, particularly a kind of LED street lamp with three kinds of color LED of red, green, blue synthesize white light.
Background technology
Present development along with urban construction, high-grade road construction increases fast, traffic safety for night, all the street lamp that meets the illumination GB need be installed on both sides of the road in the road, what at present common street lamp adopted is high-pressure mercury lamp and all kinds of fluorescent lamp or incandescent lamp, but there only have 30% electric energy to be used for to be luminous, and its complementary energy has expended with the situation of heat in vain.Greatly develop the LED street lamp of energy-conservation of consumption reduction in recent years, the LED street lamp has the luminous efficiency height, power consumption is little, response speed is fast, long service life, the security reliability height, help characteristics such as environmental protection, so the LED street lamp becomes the potentiality product of illumination market maximum, all adopt white light LEDs as light source at present LED street lamp, and in order to satisfy the high brightness demand, generally adopt 1W, the powerful white light LEDs of 2W is formed array as light source, the LED principle of luminosity of white light is that the blue light wafer adds fluorescent material, the blue light wafer relatively and the brightness of the LED wafer of other color low, the attenuation ratio of fluorescent material is bigger, so the attenuation ratio of white light LEDs is bigger, also have its caloric value of great power LED to be much higher than common LED, therefore demand a kind of Novel LED street lamp that can overcome above-mentioned shortcoming of utility model urgently.
The utility model content
The purpose of this utility model is to solve the high-power blue light wafer of available technology adopting to add that fluorescent material makes white light LEDs and make the problem that the existing decay of LED street lamp is big, luminance is low again, and a kind of LED street lamp with three kinds of color LED of red, green, blue synthesize white light is provided.A kind of LED street lamp of the utility model design with three kinds of color LED of red, green, blue synthesize white light, comprise lampshade, lamp housing, radiator, ground glass, constant-current source, it is characterized in that: the LED lamp plate is arranged in lamp housing, be welded with three kinds of LED of red, green, blue on the LED lamp plate, three kinds of LED of red, green, blue connect constant-current source after the connection in series-parallel separately.Three kinds of LED of red, green, blue on the LED lamp plate evenly distribute.The red LED wavelength is 610nm-640nm, and the green LED wavelength is 510nm-540nm, and the blue led wavelength is 450nm-480nm.The brightness ratio of three kinds of LED of red, green, blue on the LED lamp plate is 2～4: 5～7: 0.5～2.The irradiates light shape of three kinds of LED of red, green, blue is oval.On the LED lamp plate, be covered with the paste heat-conducting silicone grease and be connected radiator with flexible thermal conductive silicon film.Ground glass is arranged on lampshade.The utility model has the advantages that: adopt super bright red, green, blue three kinds of color LED synthesize white light of small-power or the warm white light source as street lamp, its life-span is far longer than the light source with high power white light LED.Its luminous efficiency height, under same power, the same terms, the road-light light-source illumination that constitutes than large power white light LED has promoted 1.5-3 doubly.It has effectively solved the decay and the high heat problem of great power LED of white light LEDs, and energy-saving effect is remarkable, long service life.Since be the light source of three kinds of color combination of red, green, blue, its colour rendering height, and display color is bright-coloured, more near daylight.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Below in conjunction with accompanying drawing and example the utility model is elaborated.
The specific embodiment
During concrete enforcement, three kinds of color LED7 are welded on the LED lamp plate 6 evenly distributedly with several low power super bright red, green, blues, by LED separately connection in series-parallel be combined into illuminator.Wherein the red LED wavelength is 610n-640nm, and the green LED wavelength is 510nm-540nm, and the blue led wavelength is 450nm-480nm.According to the wavelength and the electric current of light emitting diode, the LED7 of three kinds of colors of red, green, blue is regulated according to certain brightness ratio scope, make it be shown as white light or warm white.This proportion is: red, green, blue is respectively 2～4: 5～7: 0.5～2.As the ratio that can choose red, green, blue brightness is 3: 6: 1.All LED all use constant-current source 5 to drive, luminous so evenly, flicker free meets the application requirements of LED more, makes its life-span long.In order to meet the requirement of road lighting, its light-emitting area of the LED that uses is ellipse, adopts the lens with ellipse-shaped light shape before the LED.Wherein degree of understanding without being told is greater than 42Lux in the time of 10 meters to make power and be this kind led light source of 80W, and irradiated area is oval, has well satisfied the requirement of street lamp.And LED lamp plate 6 is connected in radiator 3 by paste heat-conducting silicone grease and flexible thermal conductive silicon film 8, will derive the heat of LED well like this.And lampshade 1 adopts ground glass 4 to carry out the secondary colour mixture, makes the photochromic uniformity of demonstration better.
