Technical field
The present invention relates to technical field of LED illumination, more specifically to a kind of four primary LED light source.
Background technology
LED (light emitting diode) has the advantages that small power consumption, service life are long, inexpensive, has been widely used in
The fields such as illumination, display.LED light source may be used as the scene regulation and control of the place such as lighting of home, dance hall, bar.LED illumination skill simultaneously
Art is also widely used for the environmental protection aspect of interior, such as uses light source of the LED light source as indoor air purification sterilizing unit.
It is photochromic that four primary LED light source includes red, green, blue, Bai Si kinds, conventional four primary LED light source be by red, green, blue,
Bai Si kinds are photochromic to be integrated into same luminescence unit.White light can make light source luminescent softer, but emitting red light chip, green
Color luminescence chip, blue luminescence chip and the luminescence chip for producing white light are arranged in matrix form, for producing the hair of white light
Optical chip is located at one jiao of luminescence unit, be only capable of with other luminescence chips of the luminescence unit at place carry out it is photochromic mix, utilize
Rate is low, causes the light wasting of resources, does not meet the trend of social energy conservation environmental protection now.
Three kinds of red, green, blue is photochromic to be produced by emitting red light chip, green emitting chip and blue luminescence chip.But
White light can not directly be produced by luminescence chip, and the generation principle of white light is in blue luminescence chip applied atop yellow fluorescence
Powder, yellow fluorescent powder is excited to produce white light by blue luminescence chip.Existing preparation method is：By emitting red light chip, green
Color luminescence chip and two blue luminescence chips are integrated into same unit, afterwards the table of a blue luminescence chip wherein
Yellow fluorescent powder is smeared in face, so that light source generation red, green, blue, Bai Si kinds are photochromic.The manufacture craft of this types of light sources is answered
It is miscellaneous, low production efficiency.Simultaneously because yellow fluorescent powder is photochromic to white light to produce important influence；But in actual production, it is single
