Example Embodiment

[0011] Such as figure 2 As shown, the design method of the spherical surface light source reflector of the present invention includes: the light reflecting surface of the reflector 2 is rotationally symmetrical along the vertical axis y, firstly determining the cross section of the spherical light source passing through the center O of the spherical light source 1, and then determining The vertical distance aA between the surface of the spherical light source and the top center of the reflector to determine the position of the top center A of the reflector 2, and to make a reflecting surface from the top center A of the reflector 2 as a starting point to ensure that the light emitted in the direction of the normal line OA of the top center of the spherical light source The light AE reflected by the light aA at the top center of the reflector 2 just becomes the tangent to the surface of the spherical light source 1, and it is ensured that the reflected light AE is not blocked by...

Abstract

The invention relates to a method for designing a sphere surface luminous light source reflector. The reflector comprises a light source and a reflector; the light source is a sphere surface luminescent light source; light reflecting surfaces of the reflector are symmetrical rotatably and axially along a vertical shaft; and the method comprises the following steps of: determining a sphere light source cross section which passes through the center of the sphere light source; and determining a vertical distance between the surface of the sphere light source and the top of the reflector, so thatthe position of the center of the top of the reflector is determined, a reflecting surface is made by taking the center of the top of the reflector as a starting point so as to ensure that a light ray which is emitted in a normal direction of the center of the top of the sphere light source and reflected by the center of the top of the reflector is parallel to tangents of the surface of the sphere light source, and ensure that the reflected light ray cannot be blocked by the sphere surface, namely the light ray emitted in the normal direction of the center of the top of the sphere light source can be led out after being reflected by the reflector once. An electrodeless lamp employing the reflector designed by the method has higher light extraction rate and higher illumination uniformity, and is favorable for popularization and application on a large scale and in a large range.

Description

technical field [0001] The invention relates to a design method of a reflector of a lighting fixture, in particular to a design method of a reflector of a lamp using a spherical electrodeless lamp as a light source. Background technique [0002] The existing high-frequency electromagnetic electrodeless lamps generally use traditional light sources. For example, point light sources such as sodium lamps and metal halide lamps are used as electrodeless lamps. Not suitable for high-frequency electromagnetic electrodeless lamps. Such as figure 1 As shown, the reflector 4 of the traditional lamp is only suitable for point light sources. When the reflector 4 is used for the spherical surface light source 3, a considerable part of the reflected light of the spherical surface light source 3 will be blocked by the spherical surface light source 3 itself, so that It will greatly reduce the light output rate of the lamp, and also reduce the uniformity of illumination of the lamp. The...
