    摘要: A multi-color LED illumination device and specifically a lens comprising a cylindrical opening extending into the lens from a light entry region at which one or more LEDs are configured. A concave spherical surface extends across the entirety of the light exit region of the lens, and a TIR outer surface shaped as a CPC extends between the light entry region and the light exit region. There are various diffusion surfaces placed on the sidewall surface of the cylindrical opening, as well as its upper planar surface and, depending on whether glare control is not needed, the exit surface of the lens. Lunes can also be configured on the sidewall surfaces of the cylindrical opening and if lessening glare is needed, also on the TIR outer reflective surface. The combination of lunes, diffusion elements, and the overall configuration of the lens provides improved color mixing and output brightness according to one embodiment. According to another embodiment, diffusion elements are manufactured and possibly increased on only select surfaces but not on the light exit region in order to lessen glare. Three light interactions in a first portion of light and two interactions in a second portion of light can improve color mixing and beam control. Those interactions includes two refractions either with an intermediate reflection or not, all of which are necessary to achieve the improved performance of the multi-color LED illumination device and lens hereof.

    摘要: A pumped fluorescent light source includes one or more mirrors that direct pumping light from one or more pump sources on a fluorescent body having a planar top surface and a convex back surface. The top surface may be coated with an anti-reflective coating and the back convex surface may be coated with a reflective coating to improve efficiency. The body top surface may also be roughened to scatter a portion of the excitation light provided from the mirror(s) to generate a white output beam. The mirror(s) have reflective surfaces disposed outside of a collection area of an output beam of the light sources, so that the collection area is not obstructed by the mirror(s). The light source also includes a collecting lens for collecting the light emitted by the body. The mirror may be a single parabolic mirror that focuses the excitation light on the body to stimulate emission.

    摘要: The present invention aims at providing an illumination device which can improve a light distribution shape while suppressing the occurrence of glare. The illumination device according to the present invention includes an LED module and a reflector. A reflecting side surface of the reflector is obtained by rotating a curve with respect to an optical axis, the curve obtained by connecting an arc defined by a circle and an arc defined by another circle substantially inscribed to the circle.

    摘要: A lighting component may include a light emitting diode (LED) positioned on a printed circuit board assembly (PCBA), and a reflector positioned on the PCBA over the LED. The LED may be configured to emit an effective span of light which may pass through the reflector from a rearward opening to a forward opening of the reflector. The reflector may include a first region with one or more surfaces configured to subtend a first portion of the effective span of light. The reflector may include a second region with one or more first surfaces configured to subtend a second portion of the effective span and one or more second surfaces configured to subtend exterior light entering the forward opening back through the forward opening. The reflector may include a third region with one or more surfaces configured to subtend exterior light entering the forward opening back through the forward opening.
