Description
Technical field
The present invention relates to the light fixture of a kind of great power LED with single-chip package or the integrated encapsulation of multicore sheet as light source, especially the light that great power LED can be sent changes photodistributed light fixture by a free-form surface lens.
Background technology
At present, be that the light fixture of light source generally all adopts LED is fixed on the heat abstractor that has fin with the great power LED, and reflect with the light that reflection shield sends LED and to make light fixture, or according to the light that LED sends compare with other point light source light-emittings that directionality is more intense, light relatively concentrates the characteristic in directive exiting surface the place ahead, add lens at the LED direction of illumination and change light and distribute.Lens generally adopt the convex lens of traditional concept, and these two kinds of structures can't realize that diversified light distribution changes, and can only realize the optically focused and the astigmatism of circular scope, do not satisfy as the needed light distribution requirements of different purposes light fixtures.
Summary of the invention:
The objective of the invention is, a kind of LED light fixture is provided,, reach its optimal light distribution effect for making the high-powered LED lamp prodigiosin according to different purposes, different luminous intensity distribution needs.
The technical scheme that the present invention is adopted for its technical problem of solution is: a kind of LED light fixture, it is characterized in that, adopting the great power LED of single-chip package or the integrated encapsulation of multicore sheet is light source, in the position of LED direction of illumination free-form surface lens 2 is set, light is injected from a side of free-form surface lens 2, penetrated by opposite side surface after reflecting, it can be the continuous smooth curved surface that convex surface and concave surface by difformity, different curvatures combine that the light of free-form surface lens 2 is injected face and exiting surface.Change and inject the surface configuration of face and the incident angle that curvature can change light, change the surface configuration of exiting surface and the direction of illumination that curvature can change refracted ray, design the surface configuration and the curvature of the face of injecting and the exiting surface of lens according to this characteristic, change its direction of illumination behind the light scioptics that realization is sent LED and light distributes, reach default light distribution effect, thereby satisfy the diversity luminous intensity distribution needs of different purposes light fixtures.
The invention provides and a kind ofly led light source is changed the light fixture of luminous intensity distribution, thereby realized carrying out luminous intensity distribution accurately and effectively according to the distribution needs of not sharing the same light with free-form surface lens.
Operation principle of the present invention is to apply satisfactory powered by direct current to LED3.During energising, the luminous work of LED3, light shines out by free-form surface lens 2, and the light that this light fixture can send LED3 effectively changes direction of illumination by the free-form surface lens refraction and carries out multi-direction multi-angle irradiation.When light directive lens, wherein a part is directly passed lens through refraction, and some can form reflection at lens surface, and especially hollow lens can be worn with new incident angle again after the reflection and penetrate lens.Under the different refraction action that free-form surface lens produced of the present invention, the light that LED3 is sent reaches the light distribution effect that needs after by free-form surface lens 2.
The invention has the beneficial effects as follows: according to the law of refraction of light, utilize free-form surface lens can change the characteristic of direction to the light that passes through, direction of illumination to light on purpose changes, can change the surface configuration of lens exiting surface and curvature and light and inject the shape of face and the incident angle that curvature changes light and the direction of illumination of refracted ray, thereby light irradiating angle, scope and the light of realizing changing the LED light fixture distribute.The light that LED is sent is by behind the free-form surface lens, can obtain the lamp distribution of ideal effect under the refraction action of the free-form surface lens of the different incident angle of setting, different surperficial curvature.
