Problems solved by technology

These secondary light distribution components will be connected with the circuit board (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 circuit board. To ensure that the light emitted by the lamps after combination is far enough, it is required that the secondary light distribution components should be as perpendicular to the circuit board as possible, and the light emitted between adjacent two should be parallel and not interfere with each other. However, the current secondary light distribution components After the optical component is connected to the circuit board, it is often tilted, and it is difficult to be perpendicular to the circuit board, which affects the light irradiation effect

Abstract

The invention discloses a reflection cup for secondary light distribution. The reflection cup comprises a reflection cup body with a reflection cavity, a positioning mounting part arranged on the reflection cup body for positioning the reflection cup body and a circuit board, and a fixing connection part arranged on the reflection cup body for fixedly connecting the reflection cup body and the circuit board. According to the connection fixing structure, the reflection cup body and the circuit board are well positioned by a vertical positioning part, and are fixed into a whole by the fixing connection part, so the reflection cup body does not incline after being connected with the circuit board and is vertical to the circuit board, and light rays are enabled to irradiate to a long distance, and a good irradiating effect is realized.

Description

technical field [0001] The invention relates to the technical field of spotlight lamps, in particular to a reflective cup used for secondary light distribution. 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 circuit board (alumin...
