Problems solved by technology

[0005] The biggest drawbacks of existing technologies are: (1) they cannot utilize the blocked sunlight; and (2) solar energy cannot be stored and utilized when there is no need for indoor lighting
When the prior art sunshade is opened, the sunlight is reflected into the sky in vain, which is of no use value and is a waste of solar energy

Embodiment Construction

[0028] The biggest flaw with existing technologies is their inability to take advantage of blocked sunlight. When the sunshade in the prior art is opened, the sunlight is reflected in the sky in vain, and cannot be utilized, which is a waste of solar energy.

[0029] Such as Figure 5 , Figure 6 As shown, the gist of the present invention is that the shading plate covers the solar cell panel on the two semicircular shading devices, so that when the shading plate is opened, the sunlight will generate electric energy when it shines on the solar cell panel. The electrical energy is sent to the battery for storage, thus solving the problem of not being able to use solar energy when the light pipe is turned off.

[0030] Such as Figure 5 , Figure 6 As shown, 1 is the light guide, 2 is the upper shading plate of a semicircular shading device, 3 is the lower shading plate of another semicircular shading device, 4 and 5 are a combination of interlocking horizontal shafts, 6 is ...

Abstract

The invention discloses a light guide tube dimmer and a light guide tube using the same. The light guide tube dimmer comprises a shading plate which can be opened and closed, wherein one side, which faces sunlight, of the shading plate is provided with a solar energy collecting device. When the dimmer is opened, energy carried in shaded sunlight is also utilized. When the dimmer is closed, the transmission of light in the light guide tube is hardly influenced. The invention also provides the light guide tube using the light guide tube dimmer. The light guide tube dimmer is arranged inside the light guide tube.

Description

technical field [0001] The invention relates to a light guide component and a light guide structure. Background technique [0002] At present, fields such as architecture often require the use of light pipes. The light pipe is a hollow tube, and the inner wall has been specially treated with high reflectivity. Therefore, the light pipe can use the principle of reflection to transmit light from one end to the other. In some special applications, it is necessary to control the luminous flux (for example, the light pipe installed in the bedroom needs to be turned off when taking a nap to ensure that the indoor brightness is low and suitable for sleep). It is to let only part of the light pass through the light guide, or let all light not pass through the light guide as needed. To achieve this purpose, it is necessary to install a shutter inside the light guide. [0003] The principle of the prior art light shutter is very simple, just block the light and prevent it from mov...
