Embodiment Construction

[0020] specific implementation plan

[0021] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0022] like Figure 1-4 As shown, a light collecting and distributing device includes a primary annular light blocking sheet 1, a compound parabolic concentrator 2, a secondary annular light blocking sheet 3, an optical fiber sleeve 4, an optical fiber 5 and an astigmatic device 6. The symmetry axes of all the above-mentioned components are on the same straight line, and the connection mode between all the components is adhesive bonding;

[0023] The upper end of the compound parabolic concentrator 2 is connected to the first-level circular light-blocking sheet 1, and the lower end of the compound parabolic concentrator 2 is connected to the secondary circular-shaped light-blocking sheet 3, and the secondary circular-shaped light-blocking sheet 3 passes through the optical fiber The sleeve 4 is connected ...

Abstract

The invention discloses a light collecting and dispersing device. The light collecting and dispersing device comprises a primary circular annular light blocking piece, a compound parabolic condenser,a secondary circular annular light blocking piece, an optical fiber sleeve, an optical fiber and a light dispersing device, wherein the symmetry axes of all the parts are on the same straight line, the upper end of the compound parabolic condenser and the primary circular annular light blocking piece are connected together through glue, the lower end of the compound parabolic condenser and the secondary circular annular light blocking piece are connected together through glue, the secondary circular annular light blocking piece is connected with the optical fiber through the optical fiber sleeve, and the tail end of the optical fiber is connected with the light dispersing device. The light collecting and dispersing device can be used in the fields such as plates, houses, machinery or the like, wherein the fields need lighting and illuminating.

Description

technical field [0001] The invention belongs to the field of solar light utilization, in particular to a light collecting and scattering device. Background technique [0002] Although the currently widely used concentrators can convert solar energy into light energy to a certain extent, they cannot meet the public's requirements for different levels of lighting because they cannot freely adjust the concentration ratio. At the same time, because the general concentrator can only be connected with a light guide element of a single size and shape, the concentrating conditions are extremely strict, which limits its popularization. Contents of the invention [0003] The purpose of the present invention is to solve the above problems and provide a light collecting and scattering device. The present invention can be used in boards, houses, machinery or other environments that require lighting and lighting, and solves the problem that general concentrators cannot freely adjust the...
