Sunflower petal type module forming down lamp reflector and down lamp reflector formed by same

Abstract

The invention provides a sunflower petal type module forming a down lamp reflector. The sunflower petal type module is in a disc shape and comprises a disc center area and a plurality of petal-like parabolic slope parts extending in the radial direction from the disc center area and arranged in a mutual spaced mode. In the formed lamp reflector structure, all the petal-like parabolic slope parts are inclined and bent towards one side of the disc center area, by setting the shapes of the petal-like parabolic slope parts, the edges of the adjacent petal-like parabolic slope parts can be fixedly connected, and therefore light passing through a reflecting face focus is reflected out in the designated spatial direction with a proper three-dimensional angle. The invention further provides a down lamp reflector formed by the sunflower petal type module. By the adoption of a surface layer aluminum material with the full reflection rate larger than or equal to 0.90, the diffuse reflection rate smaller than or equal to 0.05 or larger than 0.8, and the physical extension rate larger than or equal to 2%, the light outlet efficiency of a streetlamp is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of lighting, and in particular relates to a solar pattern module constituting a downlight reflector, especially by adopting a total reflectance greater than or equal to 0.90, a diffuse reflectance less than or equal to 0.05 or higher than 0.8, and a physical elongation greater than or equal to 0.90. Or equal to 2% of the surface layer aluminum material design of the solar chip module, the present invention also relates to the downlight reflector constituted by the above module. Background technique: [0002] At present, the light output efficiency of traditional lighting downlights is very low, usually between 0.5 and 0.7, and the smaller the light output aperture, the lower the light output efficiency. The main factor is that the reflector is made of ordinary aluminum material and then undergoes secondary anodic oxidation treatment on the surface. Since the total reflectance of the material after anodic oxi...

Problems solved by technology

[0003] At present, such as the surface layer aluminum material produced by ALANOD GmbH&Co.KG, Germany, whose total reflectance is greater than 0.90, its physical elongation is not greater than 2%, which is not suitable for multiple extrusion molding, so there is no The technology is mature, the light characteristics are stable, and the reflector module is designed and produced by using the existing surface aluminum material with a total reflectance of 0.90 or more, and the corresponding downlight products are further formed.
