Reflector component and lamp structure thereof

Abstract

Disclosed is a reflector component. The reflector component is a two-segment combination and integrally formed in design by means of injection molding and mould opening. The reflector component comprises a first reflecting segment and a second reflecting segment in smooth connection with the first reflecting segment, and reflecting surfaces of the first and the second reflecting segments are curved surfaces and both subjected to aluminum plating treatment so as to respectively reflect incident light. The invention further provides a lamp structure applying the reflector component. The reflector component adopts the two-segment curved surface combined design, one reflecting segment can improve central light strength of the light emitted by a light source, the other reflecting segment can increase the angle of emergent light, the requirements of the lamp structure for the central light strength and the light emergent angle can be met, and the light distribution requirement of the lamp structure is met. Besides, the reflector component is in the two-end combined design, thereby being simple in structure.

Description

technical field [0001] The invention relates to the lighting field, in particular to a reflector assembly and a lamp structure using the reflector assembly. Background technique [0002] Light emitting diodes (light emitting diodes, LEDs), as semiconductors that can convert electrical energy into light energy, are widely used in various lighting fixtures, such as outdoor lighting LED lights, flood lights, stage lights, miner's lamps, etc. These lights It has become an indispensable lighting appliance in people's life and work. These lamps generally include housing, light source, reflector, lampshade and other components, the light source and reflector are installed in the housing, the reflector can reflect the light emitted by the light source, and the lampshade is installed on the housing , and the light source and the reflector are packaged in the housing, the light emitted by the light source and the light reflected by the reflector are projected out by the lampshade. ...

AI Technical Summary

Problems solved by technology

[0003] However, the central light intensity and light exit angle of the light reflected by the existing reflectors are difficult to meet the lighting requirements at the same time in most cases.

For example, the busbar of the reflective surface of the miner's lamp reflector used in the market is mostly a single parabola. This kind of reflector often has two disadvantages: (1) The light output aperture of the reflector is small. Although this design can improve the central light intensity, However, it cannot meet the requirements of the spot size (that is, the angle of light exit); (2) The mirror diameter is enlarged. Although this design can meet the requirements of the spot size, it cannot increase the central light intensity.
