Abstract
The utility model relates to an LED road lamp with low color temperature, which comprises a lamp shell, a matrix type high-power LED light source, an aluminum substrate, a reflecting plate, a light distribution lens and a dustproof light-transmitting cover. The matrix type high-power LED light source, the aluminum substrate, the reflecting plate, the light distribution lens and the dustproof light-transmitting cover are respectively fixed on the lamp shell, the matrix type high-power LED light source is distributed on the aluminum substrate and connected with a circuit, and the matrix type high-power LED light source can be white LEDs and red LEDs or white LEDs and yellow LEDs or white, red and yellow LEDs which are mixed and distributed uniformly. On the basis of the three primary color light mixing principle, white light and yellow light or red light are mixed according to specific light intensity proportion, and then mixed LED spectral power distribution is changed so as to produce the light source with low color temperature. The LED road lamp with low color temperature is easy to implement and low in cost.
Description
Technical field
The utility model relates to the LED street lamp, relates in particular to a kind of LED street lamp of low colour temperature.
Background technology
Street lamp is the important component part of city illumination, and traditional street lamp adopts high-pressure mercury lamp as light emitting source, yet the luminous efficiency of high-pressure mercury lamp is low, causes the huge waste of the energy.
Along with the development of semiconductor lighting technology, adopt great power LED to replace traditional high-pressure mercury lamp gradually as the street lamp of light emitting source, led light source as the 4th generation lighting source in street lamp, occupy an leading position.Though the LED street lamp has energy-efficient performance efficiently, but the high colour temperature of LED street lamp is not resolved, and the LED colour temperature is too high to be easy to generate bad dazzle, thereby causes that dazzling, visual fatigue and vision disturb, and the ability of the light penetration mist of high colour temperature, cause traffic accident easily.
The utility model content
The utility model provides a kind of LED street lamp of low colour temperature at the above-mentioned defective of prior art, to produce comfortable low colour temperature light.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
A kind of LED street lamp of low colour temperature comprises lamp outer casing, matrix form high-power LED light source, aluminium base, reflector, lens, dustproof diffuser; Described matrix form high-power LED light source, aluminium base, reflector, lens, dustproof diffuser are individually fixed on the lamp outer casing, and the matrix form high-power LED light source is distributed on the aluminium base and with circuit and is connected; Described matrix form high-power LED light source is white light LEDs and red-light LED or white light LEDs and yellow light LED or is white light, ruddiness, the even mixed distribution of yellow light LED.
Preferably, described matrix form high-power LED light source is that white light LEDs mixes with the even of red-light LED, and white light LEDs and red-light LED light intensity ratio are 3: 1.
Preferably, described matrix form high-power LED light source is that white light LEDs mixes with the even of yellow light LED, and white light LEDs and yellow light LED light intensity ratio are 5: 2.
Preferably, described matrix form high-power LED light source is white light, ruddiness, the even mixed distribution of yellow light LED, and white light, ruddiness, gold-tinted light intensity ratio are 4: 1: 1.
As can be seen from the above technical solutions, the utility model utilizes three primary colours mixed light principle, white light is mixed according to specific light intensity ratio with gold-tinted or ruddiness to be drawn, change mixed LED spectral power distribution, obtain low color temperature light sources, its haze-penetrating capability is strong, is difficult for causing that dazzling, visual fatigue and sight line disturb, and reduces the probability that traffic accident takes place.
Description of drawings
Accompanying drawing is the utility model structural representation.
The specific embodiment
Below in conjunction with the specific embodiment the utility model is described in further detail.
Shown in accompanying drawing, the LED street lamp of the low colour temperature of the utility model comprises matrix form high-power LED light source 1, aluminium base 2, lamp outer casing 3, lens 4, dustproof diffuser 5, reflector 6; Matrix form high-power LED light source 1, aluminium base 2, reflector 6, lens 4, dustproof diffuser 5 are individually fixed on the lamp outer casing 3, and matrix form high-power LED light source 1 is distributed on the aluminium base 2 and with circuit and is connected; The matrix form high-power LED light source is white light LEDs and red-light LED or white light LEDs and yellow light LED or is white light, ruddiness, the even mixed distribution of yellow light LED.
The matrix form high-power LED light source is a white light LEDs when mixing with red-light LED, and white light LEDs and red-light LED light intensity ratio are 3: 1.The matrix form high-power LED light source is a white light LEDs when mixing with yellow light LED, and white light LEDs and yellow light LED light intensity ratio are 5: 2.The matrix form high-power LED light source is white light, ruddiness, yellow light LED when evenly mixing, and white light, ruddiness, gold-tinted light intensity ratio are 4: 1: 1.By disposing the number ratio of LED of all kinds, perhaps control the current strength ratio of LED of all kinds, perhaps the dutycycle of regulating LED of all kinds by PWM reaches the control of light intensity ratio.
Above-mentioned specific embodiment is purpose, feature and the effect that is used for describing in detail the utility model, for the personage who is familiar with this type of skill, according to the above description, may do part change and modification to this specific embodiment, its essence does not detach the spiritual category person of the utility model, all should be included in the claim of this case suitable first Chen Ming.
