Reflector, spotlight assembly and flashlight

Abstract

The invention provides a reflector with a spotlighting effect, a spotlight assembly and a flashlight. The reflector comprises a sidewall, a top opening, a bottom and a light source mounting hole, wherein the inner side face of the sidewall is a section of continuous and smooth paraboloid, and the focal length of a parabola corresponding to the paraboloid is 1mm; the top opening is located at the tail end of the opening direction of the paraboloid and has the diameter of 30mm; the bottom is located at the tail end of the necking direction of the paraboloid, and the internal surface of the bottom is connected with the inner side face of the sidewall and is vertical to the symmetry axis of the paraboloid; the light source mounting hole is located at the center of the bottom and has the diameter of 3mm; the distance from the top opening to the bottom is 15mm. According to the technical scheme of the invention, influences resulting from various factors are comprehensively taken into account, so that the reflector with the spotlighting effect, the spotlight assembly and the flashlight, provided by the invention, have the advantages that the size is delicate, and a good spotlighting effect can be achieved.

Problems solved by technology

[0003] Now general flashlights are designed by using a concentrating reflective cup and an LED light source. Some flashlights use 2 to 5 reflective cups to form a whole in order to achieve small-angle concentrating. In order to meet the illumination requirements, sometimes multiple This method makes the flashlight larger in size, and the use of multiple LED chips makes the circuit layout compact and is not conducive to heat dissipation
