According to the invention, through adding the yellow emitting phosphor on the high-voltage blue chips and red chips, the luminous efficiency and the color rendering index are improved, the severe problem of color drifting is solved, and the luminous efficiency is improved by more than 25% compared with those of low-voltage chips. A warm white light source is packaged through adding the yellow or green emitting phosphor on the blue chips and the red chips, thus the color rendering index can reach more than 90.
Description
Technical field
A kind of led light source of the present invention, particularly a kind of illumination level high-power LED light source.
Background technology
At present, worldwide energy shortage has caused the great attention of various countries to power-saving technology, is developing energetically such as solar energy, and in the time of renewable and clean energy resources such as wind energy, various countries also utilize in rational and effective and strengthened dynamics aspect the energy.Being reflected in the illumination aspect is exactly constantly weeding out the old and bring forth the new and extensive use of various new light sources.This wherein, long and its high reliability has caused concern more and more widely and progressively has been applied to lighting field light emitting diode with its low energy consumption, high light efficiency, life-span.Because the restriction that is subjected to the led chip making technology is with the axial restriction of led light source, therefore single chips encapsulated LED is difficult to realize the demand of throwing light on, and led light source also can only reach the illuminating effect of LED by light distribution device.At present, along with the maturation of led chip and packaging technology, the LED brightness requirement can satisfy the demand of illumination level, and the LED solid-state illumination has become trend.Energy-conservation, environmental protection, safety, the color rendering index height, life-span length is the distinguishing feature of LED.In application facet, particularly aspect street lighting, the application of LED can bring into play more that it is energy-conservation, the advantage of environmental protection.But the luminous axial property of LED is its maximum restriction in the lighting design and use, is difficult to the distribution curve flux of realizing that light fixture is comparatively desirable.This becomes a difficult problem of being badly in need of solution in the LED illumination application.
Present great power LED warm white source encapsulation scheme, the main blue chip that uses adds yellow fluorescent powder and red fluorescence powder, the colour temperature drift is serious, luminous efficiency is low, colour rendering index is not high, poor heat stability, lights back colour temperature drift for a long time seriously, and the luminous flux sustainment rate is low.
Summary of the invention
At above defective, the drift of prior art LED encapsulating structure colour temperature is serious, luminous efficiency is low, colour rendering index is not high, poor heat stability in order to solve, it is serious to light back colour temperature drift for a long time, and the problem that the luminous flux sustainment rate is low the invention provides a kind of novel great power LED integrated optical source.
For achieving the above object, the present invention is achieved through the following technical solutions:
A kind of novel great power LED integrated optical source, comprise: support, blue chip, red light chips, be filled in yellow or green emitting phosphor between support and the led chip, and several red light chips and blue chip be installed proportionally on the support of exposed portions serve, interlaced and the even layout of described red light chips and blue chip is filled with yellow or green emitting phosphor between the outer surface of red light chips and blue chip and support.
Described great power LED integrated optical source is used the encapsulation of high voltage chip, and its luminous efficiency improves more than 25% than low voltage chip.
Described great power LED integrated optical source uses blue chip and red light chips adds yellow or green emitting phosphor is packaged into the warm white source, and its colour rendering index can reach more than 90.
Described great power LED integrated optical source is used the blue chip and the red light chips of fixed proportion, can the passing ratio coefficient realizes the light source of different capacity.
Described great power LED integrated optical source uses red light chips to substitute red fluorescence powder encapsulation warm white source, and its Heat stability is good has been avoided color drift in life period.
The fixed ratio of red light chips and blue chip.
The present invention adds yellow fluorescent powder by using high pressure blue chip and red light chips, so red, yellow, blue three kinds of colour systems are organically combined, reach the effect of sending out warm white, and can reach the purpose of regulating the white light saturation degree by regulating the ratio of red light chips and blue chip.Both improved luminous efficiency and colour rendering index, and solved the serious problem of colour temperature drift again, its luminous efficiency improves more than 25% than low voltage chip.Use blue chip and red light chips adds yellow or green emitting phosphor is packaged into the warm white source, its colour rendering index can reach more than 90.Use the blue chip and the red light chips of fixed proportion, can the passing ratio coefficient realize the light source of different capacity.Use red light chips to substitute red fluorescence powder encapsulation warm white source, its Heat stability is good has been avoided color drift in life period.
