Reflecting cup pedestal used for connection with circuit board

Abstract

The invention discloses a reflecting cup pedestal used for connection with a substrate. The reflecting cup comprises a pedestal provided with a reflecting cavity, and a locating hole and a locating bayonet which are arranged on the upper surface of the pedestal, wherein the substrate is further provided with a locating installation part used for locating the pedestal and the substrate, a fixed connection part used for fixedly connecting the pedestal and the substrate, and a lens locating installation groove used for coinciding a lens and an axis of the pedestal. The reflecting cup has the advantages of simple structure, low cost and good secondary light distribution effect, the pedestal and the substrate are quickly and accurately installed, inclination can be prevented after a secondary light distribution component is connected to the substrate, and the pedestal is vertical to the substrate, so that light ray can be irradiated far enough, thus the reflecting cup has good illuminating effect.

Description

technical field [0001] The invention relates to the technical field of spotlight lamps, in particular to a reflector base used for connecting with a substrate. Background technique [0002] Now LED lighting is more and more widely used because of the advantages of environmental protection, energy saving, and fast response. Since the luminous characteristics of LEDs are half-plane near-Lambert type, it is necessary to use LED secondary light distribution devices to adjust the light when collimating and concentrating light. Conventional LED secondary light distribution devices are mostly reflective cups and reflectors. Etc. For example, the Chinese invention patent whose patent publication number is CN101660711A and whose patent publication date is 2010.03.03 discloses a LED secondary reflection light distribution device, which uses reflective cups for secondary light distribution. These secondary light distribution components will be connected with the substrate (aluminum su...

AI Technical Summary

Problems solved by technology

These secondary light distribution components will be connected with the substrate (aluminum substrate) to form the required LED lamps. In many cases, multiple LED lamp beads and multiple secondary light distribution components are placed on the substrate. The light emitted by the rear lamps is far enough, and the secondary light distribution components are required to be as perpendicular to the substrate as possible, and the light emitted between adjacent two is parallel and does not interfere with each other. However, the current secondary light distribution components and After the substrate is connected, it is often tilted, and it is difficult to be perpendicular to the substrate, which affects the light irradiation effect
