A split-type fixed trans-reflective sunlight transmission device with a reflective handle

Abstract

The invention relates to a split-type fixed transmission-reflection sunlight transmitting device with a reflection handle, which comprises an optical fiber (6) and a single-layer or multi-layer lens group (7) formed by a front single-layer or multi-layer Fresnel lens (convex lens) (1) and a rear single-layer or multi-layer positive or negative Fresnel lens (convex or concave lens) (2). The characteristics lie in that the single-layer or multi-layer lens group (7) is connected to a reflection handle (3) behind, and an angle design of a back reflecting surface of the reflection handle (3) can enable centralized parallel light beams formed by various angles of incident sunlight after passing through the single-layer or multi-layer lens group (7) to be reflected by the back reflecting surface of the reflection handle (3) to the optical fiber (6) at the end of the reflection handle. The device is of a split type design, the front surface and the back surface of the reflection handle (3) are consistent in shape. The split-type fixed transmission-reflection sunlight transmitting device with the reflection handle (10) is formed by spliced by sunlight transmitting units (9). The split-type fixed transmission-reflection sunlight transmitting device with the reflection handle does not need to adjust settings according to time and seasons, has the characteristics of small size, simple structure, low manufacturing cost, convenient transportation and installation and the like, can be arranged on the roof or the outer wall surface, and is suitable for domestic applications.

Description

technical field [0001] The patent of the present invention relates to a fixed sunlight transmission device, in particular to a split-type fixed transmission-reflection sunlight transmission device with a reflective handle, which is a household sunlight transmission device without moving parts. Background technique [0002] At present, there are few household sunlight transmission devices in the market. The characteristics of the sunlight transmission devices recorded in the literature are: a complex automatic sunlight tracking system, and a high sunlight benefit rate; the disadvantages are: the automatic tracking system has a high failure rate, complicated installation, and expensive. The maintenance cost is high, which is not conducive to popularization and application. Contents of the invention [0003] The purpose of this invention patent is to propose a simple sunlight transmission device that does not require moving parts, does not need to be adjusted according to tim...
