Background technology

At present; The ripe in succession illumination that also is used in large space places such as road, tunnel, square, factories and miness, gymnasium in a large number of multiple light source technology; Especially be main with white light LEDs, Metal halogen lamp, electrodeless lamp, cold white fluorescent lamp etc., gold-tinted is main with sodium vapor lamp, warm colour fluorescent lamp.In a single day light fixture uses above-mentioned a certain light source, and then this light fixture just can only send the light of certain certain spectroscopic characteristics, and therefore this light fixture just uses inconvenience or not energy-conservation at some lighting environment (as: under the mesopic vision environment).

Along with the raising and energy-conservation the pressing for of China's illumination of lighting engineering research level, theoretical: as to it has been generally acknowledged that working as ambient brightness is higher than 3cd/m according to middle educational inspector's light measurement that CIE (International Commission on Illumination) proposes ²The time, be photopic vision; When ambient brightness is lower than 0.01cd/m ²The time, be noctovision; Occur in the lightness environment between photopic vision and the noctovision, be mesopic vision.

The road lighting visual zone that mediates usually according to the field measurement situation.Under the mesopic vision condition; Taper photosensory cell and shaft-like photosensory cell in the human eye work simultaneously; But these two types of photosensory cell degree of participation are different with light source light spectrum characteristic etc. and change along with ambient brightness, and directly caused the maximum of mesopic vision human eye luminous efficacy also to change thereupon.

Its Changing Pattern is: visible brightness obviously promotes along with the reduction of the brightness that conforms to contain the light (partially white light) of more bluish-green wavelength components in the light source light spectrum, i.e. the S/P of this light source＞1 (light that on behalf of the spectrum of light source, S/P under noctovision and photopic vision condition, produce leads to and compares); Visible brightness obviously reduces along with the reduction of the brightness that conforms to contain the light (partially gold-tinted) of more yellowish green wavelength components in the light source light spectrum, i.e. the S/P of this light source＜1.Therefore, under the mesopic vision condition, reach the identical needed light source power of visual effect, white light source (S/P＞1) is more much lower than inclined to one side gold-tinted light source (S/P＜1) partially.

China's city illumination design standard clearly proposes the street lamp lighting energy saving to be required and method standard code: except that residential area and minority have the road of specific (special) requirements, should select following measures reduction road surface brightness at dead of night; 1. adopt dual source lighting fixture, close a light source during late into the night.The magnitude of traffic flow in the late into the night is little, closes a light source, can reach energy-conservation purpose, does not influence the road surface luminance uniformity again.Adopt the country of this measure many,, should generally carry out this measure because the late into the night, vehicle flowrate was little.

By on can know, the common road before midnight ambient brightness upper end areas of vision that mediates, near or reach the photopic vision environment, the size of the S/P value of light source influences not obvious to the vision visibility of human eye; And the late into the night, ambient brightness can descend a lot, the following petiolarea of the vision that mediates, and the size of the S/P value of light source is very big to human eye vision visibility influence, can select the inclined to one side white light source of the littler S/P of power＞1 thus, and not only light is looked effective, and more energy-conservation.But the inclined to one side gold-tinted that more yellowish green wavelength is arranged reveals that ability is strong, and visibility is better than inclined to one side white light source again under the photopic vision condition.If lighting is only selected a kind of light source of special spectrum; No matter be S/P＞1 or S/P＜1; All can not well satisfy the variation of above-mentioned road lighting mesopic vision ambient brightness; Therefore have only light source with two kinds of special spectrums to be blended in the light fixture and through controller start-stop respectively, make the spectrum of the light that light fixture sends adjustable, to satisfy the needs of different scenes.
