Description
Technical field
The present invention relates to a kind of means for correcting, relate in particular to a kind of white light LEDs light fixture colour rendering index and color temperature correction device.
Background technology
Colour rendering index and colour temperature are to weigh two important indicators of light source quality.Colour rendering index is the reducing degree of reaction light source to the object true colors, and its value is high more, and good more to the reducing degree of object true colors, display effect is true to nature more; On the contrary, if colour rendering index is low more, light source is poor more to the color reducing degree of object, and display effect is got over distortion.In the middle of conventional lamp, the colour rendering index of fluorescent lamp, incandescent lamp is 100, and the colour rendering index of electricity-saving lamp is 80-90, and the colour rendering index of LED lamp is 70-90.Colour temperature is the instrument that is used for calculating and weighing the light color composition specially, and colour temperature is high more, just gets over cool beauty for people's visual effect, and colour temperature is low more, gives people's visual effect warm more.When color temperature value during at 3300K, belong to reddish white, give the warm steady sense of people; When color temperature value during at 3000-5000K, the pure white in the middle of belonging to is given people's feel cool; When color temperature value during greater than 5000K, belong to the blue white of band, give the cold sensation of people.
Along with the maturation of LED technology, the LED light fixture is used widely, but owing to reason, the especially colour rendering index of white light LEDs light fixture and colour temperature and conventional lamp such as being limited by luminosity own differ bigger, its colour rendering index is merely 70-90.High color temperature white light cool beauty is dazzling, a little less than the colour rendering; The thick and heavy dimness of low color temperature white light, colour rendering index is low.The intensity of light source and colour rendering index are not relations in direct ratio again, and colour rendering index but can descend when lamp brightness reaches ideal value.Be to improve colour rendering index, the method that adopts at present is to widen the width of fluorescent material excitation spectrum, makes light trend long wave direction, but brightness descends thereupon, if use rouge and powder, its unstable properties, colour rendering index can only reach about 80-90, colour temperature also will reduce.Through inquiry correlative study achievement, the result shows does not still have direct valid approach can realize the improvement of white light LEDs light fixture aspect colour rendering index and colour temperature simultaneously at present.
Summary of the invention
The invention provides a kind of white light LEDs light fixture colour rendering index and color temperature correction device; Through fully utilizing in blue-ray LED and the red-light LED and white light LEDs; Reduce or improve the colour temperature of white light LEDs, improve its colour rendering index, realize the synchronous improvement of white light LEDs on colour rendering index and colour temperature.
In order to realize above-mentioned technical goal, the present invention has adopted following scheme:
A kind of white light LEDs light fixture colour rendering index and color temperature correction device; Comprise white LED lamp pearl, ruddiness and blue-ray LED bi-colour light pearl, LED aluminium base, white LED lamp pearl light-emitting window, ruddiness and blue-ray LED bi-colour light pearl light-emitting window and light barrier; White LED lamp pearl, ruddiness and blue-ray LED bi-colour light integument are installed on the aluminium base, and white LED lamp pearl light-emitting window, ruddiness and blue-ray LED bi-colour light pearl light-emitting window are arranged on the light barrier.
On the LED aluminium base, blue light and red-light LED bi-colour light integument are around arranging and fixing, and the white LED lamp pearl is fixed on the central point of aluminium base.
On light barrier, a plurality of blue lights and red-light LED bi-colour light pearl light-emitting window evenly are provided with, and match with blue light and red-light LED bi-colour light pearl position, and the centre is provided with a white LED lamp pearl light-emitting window.
Ruddiness and blue-ray LED bi-colour light pearl are single two-in-one LED lamp pearl, through DMX512 whistle control system control ruddiness or blue light source output.
The invention has the beneficial effects as follows: through in blue light or the red-light LED with low colour temperature or high color temperature white light LED; Thereby improve or reduce the colour temperature of white light LEDs; Improve the colour rendering index of white light LEDs; Realize the synchronous improvement of white light LEDs on colour rendering index and colour temperature, improve the lighting effect of white light LEDs, be adapted to fields such as light of stage illumination, road lighting and Landscape Lighting.
