Abstract
The utility model belongs to the technical field of light-emitting diodes (LED), and particularly relates to an efficient luminous LED street lamp which comprises a lamp shell body, a lamp body base plate and LED luminous sources. The lamp body base plate is fixed on the lamp shell body, and the LED luminous sources are arranged on the lamp body base plate and comprise a plurality of white light LEDs and at least one green light LED. Due to the fact that the green light LED is additionally placed on the luminous sources of the LED street lamp, the lacked spectrum of long waves of the white light LEDs is complemented, the color rendition of the LED street lamp is obviously improved, cost is low, and luminous efficiency is high.
Description
Technical field
The utility model belongs to the LED technical field, is specifically related to a kind of LED street lamp of high light efficiency.
Background technology
The equal radiation continuous spectrum of sunshine and incandescent lamp in wavelength of visible light (380nm-760nm) scope, is comprising various coloured light such as red, orange, yellow, green, blue, blue, purple.Object demonstrates its true colors under the irradiation of sunshine and incandescent lamp, but works as object under the irradiation of the gas-discharge lamp of discrete spectrum, and color relation has distortion in various degree.Light source is called colour rendering to the degree that presents of object true colors, and Ra represents with colour rendering index, and the Ra value is more big, and the colour rendering of light source is more good.Colour rendering index is the quantitative assessment to color rendering properties of light source, is as the criterion with standard sources, and the colour rendering index of incandescent lamp is defined as 100, is considered as desirable reference light source, and the colour rendering index of all the other light sources all is lower than 100.
The spectrum of LED is very narrow, generally all is now to adopt blue chip to join yellow fluorescent powder to obtain white light, and colour rendering index is very low.The LED street lamp requires very high for light efficiency, must reach the light efficiency requirement of road lighting, yet its apparent finger (colour rendering index) of the lifting of the light efficiency of LED light emitting source own will descend, this makes that the apparent finger of LED light emitting source street lamp of high light efficiency is very low, refer to if improve to show, the light efficiency of LED light emitting source street lamp will be had a greatly reduced quality, and the LED light emitting source price of high apparent finger, high light efficiency is also very high, this has restricted the range of choice of downstream application industry to a certain extent, so people thirst for obtaining a kind of new LED street lamp always.
The utility model content
At the technological deficiency that LED street lamp in the prior art exists, the purpose of this utility model is to provide a kind of LED street lamp of high light efficiency.
A kind of LED street lamp of high light efficiency comprises lamp housing, lamp body substrate and LED light emitting source, and described lamp body substrate is fixed on the lamp housing, and described LED light emitting source is arranged on the lamp body substrate, and described LED light emitting source comprises a plurality of white light LEDs and at least one green light LED.
Further, described a plurality of white light LEDs are connected in parallel after being connected into many group LED lamp groups, and at least one group of LED lamp group is in series with green light LED in described many group LED lamp groups.
Further, the peak wavelength of described green light LED is between 620～660nm.
Further, the peak wavelength of described green light LED is between 630～650nm.
Further, the peak wavelength of described green light LED is 645nm.
The utility model has added green light LED in the light source of LED street lamp, completion long wavelength's the spectrum of white light LEDs disappearance, obviously improved the color reducibility of LED light emitting source street lamp, improved colour rendering index, and can be at high light efficiency, carry out rational allocation under the condition cheaply, avoided unnecessary loss in the prior art.
Description of drawings
Figure 1 shows that structural representation of the present utility model;
Figure 2 shows that the utility model circuit connection diagram.
The specific embodiment
For further detailed elaboration the technical solution of the utility model, be elaborated below in conjunction with accompanying drawing.
As shown in Figure 1 and Figure 2, the utility model discloses a kind of LED street lamp of high light efficiency, comprise lamp housing 1, be fixed on the lamp body substrate 2 on the lamp housing and be arranged in LED light emitting source on the lamp body substrate 2, described LED light emitting source comprises a plurality of white light LEDs 3 and at least one green light LED 4.
A plurality of white light LEDs 3 described in the utility model is connected in parallel after being connected into five groups of LED lamp group L1, L2, L3, L4, L5, described LED light emitting source lamp group L1, L2, L3, L4, L5 are in series with green light LED 4 at least one group, as shown in Figure 2, LED lamp group L1 is in series with a green light LED 4, and rational allocation can be carried out according to actual conditions in the required number of green light LED 4 and the position of distribution.
The peak wavelength of green light LED 4 described in the utility model is between 620～660nm; Also can select the peak wavelength of green light LED 4 between 630～650nm; The peak wavelength of preferred green light LED 4 is 645nm.
The utility model has added green light LED in the light source of LED street lamp, completion the spectrum of long-wave band of white light LEDs disappearance, obviously improved the color reducibility of LED street lamp, improved colour rendering index, and can be at high light efficiency, carry out rational allocation under the condition cheaply, avoided in the prior art improving to show in the mode of sacrificing light efficiency referring to the unnecessary loss brought.
The above is only with convenient explanation the utility model, in not breaking away from creation spirit category of the present utility model, knows any simple modification and distortion that the personnel of this technology do, still belongs to protection domain of the present utility model.
