Reflector assembly and lamp using the reflector assembly

Abstract

A reflector assembly is a multi-curved-surface combined type reflector. An injection molding and die sinking integrally formed design is adopted. The reflector assembly comprises a first reflecting surface, a plurality of second reflecting surfaces and a plurality of connecting surfaces. The first reflecting surface is in transition connection with the adjacent second reflecting surface through the corresponding connecting surface, and every two adjacent second reflecting surfaces are in transition connection through the corresponding connecting surface. The first reflecting surface and the second reflecting surfaces are all paraboloids, and are aluminized to respectively reflect the incident light rays. The invention further provides a lamp with the reflector assembly. A light distributing of the lamp is formed by the reflector assembly, collimating center parallel light rays can be formed through the incident light rays, the taper light spot outline is formed on an irradiated surface, the requirements for the central light strength and the light ray emitting angle of the lamp can be met, and thus the reflector assembly meets the requirement for light distribution of the lamp.

Description

technical field [0001] The invention relates to the lighting field, in particular to a reflector assembly and a lamp using the reflector assembly. Background technique [0002] Light emitting diode (light emitting diode, LED), as a semiconductor capable of converting electrical energy into light energy, is widely used in various lighting fixtures due to its advantages of high efficiency, low energy consumption, and long life, such as outdoor lighting LED lights, projection lights, etc. Lamps, stage lights, miner's lamps, etc. These lamps have become indispensable lighting appliances 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 so...

Problems solved by technology

[0003] However, since the light intensity of LEDs is approximately cosine-distributed, the central light intensity and light exit angle of the light reflected by the existing reflectors are difficult to meet the lighting requirements in most cases. Therefore, it is particularly important to distribute light to LED light sources. important

For example, the busbars of miner's lamp reflectors used in the market are mostly rotationally symmetrical parabolas. This kind of reflector can only form rotationally symmetrical circular light spots, and its central light intensity and light emission angle often cannot meet the lighting requirements at the same time.
