[0002] Infrared light occupies a large proportion of sunlight, and this part of light cannot be well absorbed by solar cells and generate electricity, resulting in great waste
In addition, in some power-deficient areas and when there is a power outage, there is still a lack of a set of infrared light-to-visible light-changing devices with simple structure and easy fabrication for auxiliary lighting.

[0034]When the device of the present invention is provided with nine concave mirrors, namely concave mirror I1, concave mirror II4, concave mirror III5, concave mirror IV7, concave mirror V8, concave mirror VI10, concave mirror VII11, concave mirror VIII13, concave mirror IX14, The device also includes support 2, vacuum chamber I24, vacuum chamber II25, vacuum chamber III26, vacuum chamber IV27, tungsten sheet I17, tungsten sheet II19, tungsten sheet III21, tungsten sheet IV23, tungsten sheet support I16, tungsten sheet support II18, Tungsten sheet support III 20, tungsten sheet support IV 22, infrared-transmitting glass window I3, infrared-transmitting glass window II6, infrared-transmitting glass window III9, colorless optical glass window 12 and transparent glass shell 15, the structural diagram is as follows figure 2 As shown, in an ideal situation, when the concave mirror I1 receives continuous and stable infrared light with a wavelength of 1.4-12 μm vertically irradiated...
Embodiment 3
[0036] The device for changing infrared light to visible light according to the invention can be used for auxiliary lighting. In a dark environment, there are a lot of infrared rays in the space, but the light intensity is relatively weak. Usually, the device can be equipped with nine or more, such as eleven concave mirrors, thirteen concave mirrors, etc.

Abstract
The invention relates to a method and a device for changing infrared light into visible light and belongs to the technical field of optics. The device comprises a concave mirror group, tungsten sheets, a vacuum chamber and a translucent glass window arranged at the concave mirror center; the concave mirror group is formed by coaxially arranging at least seven concave mirrors in sequence, focal points share a line, the concave mirror I is connected with the concave mirror II through a support frame, and except for the concave mirror I, the adjacent concave mirrors are fixedly connected with each other and are oppositely arranged at an interval; the tungsten sheet I is fixed at the focal point of the concave mirror I and the concave mirror III or at a focal plane; the tungsten sheet II is fixed at the focal point of the concave mirror II and the concave mirror V or at a focal plane; the tungsten sheet III is fixed at the focal point of the concave mirror IV and the concave mirror VII or at a focal plane. According to the method and the device provided by the invention, light rays are irradiated onto the concave mirror I and are continuously reflected by the concave mirrors to be converted to the tungsten sheets in the vacuum chamber, so that the infrared light is finally changed into the visible light through continuous repetition. The device provided by the invention can improve the utilization rate of solar cells for sunlight and can be used for auxiliary lighting and solar power generation.
Description
technical field [0001] The invention relates to a method and a device for changing infrared light into visible light, and belongs to the field of optical technology. Background technique [0002] The infrared part of sunlight occupies a large proportion, and this part of the light cannot be well absorbed by solar cells and emit electricity, resulting in great waste. In addition, in some power-deficient areas and when there is a power outage, there is still a lack of a set of infrared light-to-visible light-changing devices with a simple structure and easy fabrication for auxiliary lighting. Contents of the invention [0003] The purpose of the present invention is to provide a method and device for converting infrared light into visible light, through concave mirror group, tungsten sheet, infrared-transmitting glass window and colorless optical glass window, etc., so that the infrared light that cannot be used in space can be converted into visible light , used for auxili...
