The light-distribution integrative type LED light source is characterized in that a square trumpet-shaped concave lens light-distribution device is arranged and installed on the fluorescent layer and is fixed on the LED bracket to form an LED light source with a light-distribution integrative type structure, and the LED light source can achieve the effect of light distribution and can also realize the minimization of the cost.

Description

Light-distribution integrative LED light source
Technical field
The invention belongs to a kind of led light source, particularly a kind of illumination level high-power LED light source.
Technical background
The innovation photoelectric technology promotes energy-saving and emission-reduction, practices scientific development, and the people benefit the society! 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 be to satisfy the demand of illumination level, and the LED solid-state illumination has become trend.Energy-conservation, environmental protection, safety (low voltage drive), 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.
Summary of the invention
The objective of the invention is the light that the light fixture at LED, particularly LED road lamp send with LED and have axial property, the problem of brightness irregularities appears in the light that makes light fixture go out, and proposes a kind of light-distribution integrative LED light source that can change the LED lighting angle.
Light-distribution integrative LED light source of the present invention comprises led support, led chip, and fluorescence coating is characterized in that: be provided with on the fluorescence coating lens light distribution device is installed, and be fixed on the led support and constitute the led light source of light-distribution integrative structure.The lens light distribution device that is provided with on its fluorescence coating is preferably and directly is packaged on the support, constitutes integrated formed structure with led support, can realize minimization of cost like this.
Light-distribution integrative LED light source of the present invention, it is that originally the led light source desirable illuminating effect that irradiates that breaks away from that light distribution device also can be autonomous (is that light-distribution integrative LED light source of the present invention and lamp housing are when being assembled into light fixture, must not join light distribution device in addition), and reduced the organization plan of cost of manufacture greatly.It is made of led support, led chip, fluorescence coating, transmission light distribution device.Its structure is followed successively by: led chip is installed on led support; Fluorescence coating is set on led chip; On fluorescence coating, be provided with the lens light distribution device is installed.Its lens light distribution device can be the lens of convex lens, concavees lens, Fresnel lens or other special construction.Its preferred lens light distribution device is square flaring concavees lens, its lens light distribution device half through R1 numerical value in the 8-30mm scope, preferred half through R1=21.5mm; Half through R2 numerical value in the 50-90mm scope, preferred half through R2=78.5mm.The lens light distribution device can adopt light transmittance high temperature resistant preferably, anti-xanthochromia transparent material, transparent PP C material or transparent organic glass or clear optical glass or transparent polyformaldehyde or transparent poly charcoal acid ester or transparent polystyrene or one of transparent polyethylene or transparent silica gel form by the dies with epoxy compound encapsulation.Material selection is as transparent PP C material, PMMA (lucite) material, and POM (polyformaldehyde) material, PC (poly charcoal acid ester) material, PS (polystyrene) material, PE (polyethylene material) material, optical glass or other leaded light performance optical material preferably be good.Lens light distribution device (4) also can parts mode and support (1) fixing, also available molding mode directly is encapsulated on the support (1), obtains integrated light-distribution integrative LED light source.Lens light distribution device (4) is positioned at led chip and above the fluorescence coating, led light source shines out through the lens light distribution device and reaches light distribution effect, external form that can also be by changing the lens light distribution device and angle or male and fomale(M﹠F) make the LED illumination reach different effects in addition! It has solved the luminous axial problem of LED, no longer needs light distribution device in addition and reaches the effect of illumination. realized that the led light source luminous intensity distribution is integrated.
Beneficial effect of the present invention:
Light-distribution integrative LED light source of the present invention, its automatic light source lens light distribution device, need just can not reach light distribution effect by light distribution device in addition, save manufacturing cost greatly and dwindled space originally, can make the manufacturing of littleizationr of product, satisfied the powerful transformation of LED space, and efficiently solve ray axis tropism problem in the LED lamp applications, obtain comparatively desirable street street lighting distribution curve flux, be very suitable for LED die set light source street lamp, in the commercial market great business opportunity is arranged, have remarkable social benefit and higher market efficiency.
