Abstract: A method for designing uniform illumination reflector, which has a light entering opening and a light emitting opening, includes the steps of: determining a light source, the diameter of an illuminated surface and the distance between the light source and the illuminated surface, determining the maximum emitted half-angle of the reflector, and determining an aperture of the light entering opening; in a two-dimensional plane, forming multiple line segments by using one end point of the light entering opening as the start point, determining the slope and the end point for each line segment using the reverse tracing method and the iterative method and forming one curved line by the multiple line segments; and rotating the generating line around the axis of the reflector to obtain the reflective curved surface of the inner wall of the reflector.

Abstract: An LED light-emitting module and a manufacturing method thereof are provided. The LED light-emitting module comprises a substrate provided with at least one LED core, wherein the substrate has an interlayer made of ceramic materials and coated with copper foils at two sides; the copper foil at one side of the interlayer is etched to form at least one soldering pad and a conductor; the number of the soldering pads is equal to that of the LED cores; each LED core is fixed on one soldering pad; and one pole of the LED core is welded on the soldering pad while the other pole is connected with an adjacent soldering pad or the conductor through a gold thread.

Abstract: A beam collection combining LED illumination light source includes a substrate. One or more LED chips (30) are provided on the substrate. Upon each LED chip, a corresponding reflective cup (40) is provided. Each LED chip is located at the bottom of the reflective cup. The reflective cup is a revolving body. The inner wall of the reflective cup is a curved surface bended inwards. The curved surface is a primary optical curved surface.
