The specific embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
In embodiments of the present invention, the inner surface of spotlight reflector is designed to stepped multilayer free form surface, the light that light source sends parallel outgoing after the free form surface reflection reach spotlight effect, and size is less.
The inner surface of the spotlight reflector that the embodiment of the invention provides has the multilayer free form surface, and described free form surface distributes up and down, and stepped arrangement, and the height of described free form surface is 3～7mm; The datum level of each free curved surface is parabola, and described paraboloidal focal length is 3～7mm.
The spotlight that the embodiment of the invention provides comprises: a substrate, be located at the LED of described substrate and be located at reflector on the described substrate; The inner surface of described reflector has the multilayer free form surface, and described free form surface distributes up and down, and stepped arrangement, and the height of described free form surface is 3～7mm; The datum level of each free curved surface is parabola, and described paraboloidal focal length is 3～7mm; Described LED is located in the described paraboloidal focus, and the optical axis of described LED is perpendicular to described substrate, the light that described LED sends parallel outgoing after described free form surface reflection.
Below to be example with LED as light source be elaborated to the specific implementation of the embodiment of the invention:
See also Fig. 1, the spotlight that the embodiment of the invention provides comprises a substrate 51, be located at the LED50 and the reflector of being located on the substrate 51 52 of substrate 51, the inner surface of this reflector 52 has multilayer free form surface 21, it is that the datum level of each free curved surface 21 is same parabola that each free curved surface 21 is based upon on the parabolic datum level, the curvature of each free curved surface 21 is all approaching with the curvature of the datum level (parabola) of correspondence position, different free form surfaces are to the luminous luminous intensity distribution that carries out of light source zones of different, it is that the light that 21 couples of LED50 of each free curved surface send has converging action that the light that each free curved surface 21 sends LED50 reflexes to identical central area, and the reflection results of each free curved surface 21 stacks up and forms the light distribution effect of optically focused.
As Fig. 2～shown in Figure 4, each free curved surface 21 distributes up and down, and stepped arrangement, and the structure of free form surface 21 is divided simple relatively.The height of free form surface 21 is preferably 3～7mm in the present embodiment, and correspondingly, paraboloidal focal length is preferably 3～7mm.LED50 is located in the paraboloidal focus in the embodiment of the invention, and its optical axis is perpendicular to substrate 51, and the light that LED50 sends is through free form surface 21 reflections, approaching parallel outgoing is to identical central area, light is comparatively concentrated, and the outgoing beam angle is less, and spotlight effect is comparatively desirable.The inner surface of reflector 52 is subdivided into multilayer free form surface 21 in the embodiment of the invention, and every layer of free form surface 21 all can be realized accurate luminous intensity distribution, thereby can design undersized reflector.The light that LED50 sends is outgoing through free form surface 21 primary events only, and light decay is little, the efficient height of spotlight.In addition, LED50 is that lateral type is placed, and also helps anti-dazzlely, avoids light pollution.
For strengthening the illumination in the beam angle, the embodiment of the invention adopts the great power LED with four chips, and these four chips are square arranges, and the luminous angle of great power LED is preferably 100～120 °.For improving the reflection efficiency of reflector, above-mentioned free form surface 21 takes anodised aluminium to handle.
The embodiment of the invention is chosen some spotlights and is carried out simulation test, and wherein the luminous flux of LED is 600 ± 50lm, and half light intensity beam angle is 110 ± 5 degree, and the encapsulation diameter is 7.5 ± 0.5mm; The parabolic focal length of preferred reflector 52 is 5mm, and the height of preferred free form surface 21 is 5mm.As shown in Figure 5, the light that LED sends is through the reflector outgoing, and beam angle is 4.8 degree, satisfies the optically focused requirement.
