Embodiment 1

[0039] In this embodiment, a concave reflector is used to reflect light, which is defined as an arc shape.

[0040] Since the light in the semi-underground garage / semi-basement is dark, more sunlight is irradiated into the semi-underground garage / semi-basement during the day, and it is especially necessary to collect more light.

[0041] figure 1 The overall schematic diagram of the automatic concentrating and scattering instrument provided for this embodiment, the automatic concentrating and scattering instrument includes a concentrating area, a transmissive area and a divergent area, the concentrating area is provided with a first concave reflector 1, and the transmissive area is provided with The convex transmissive mirror 2 is provided with a second concave reflector 3 and a convex reflector 4 in the diverging area.

[0042] The first concave reflector 1 and the second concave reflector 3 are block concave reflectors, such as figure 2 shown. Convex mirror 2 is a semi-c...

Embodiment 2

[0048] The principle of this embodiment is the same as that of Embodiment 1, but the internal mirror reflection of the spherical surface is used to concentrate light, and the convergence of the light paths is different. Defined as spherical.

[0049] Figure 6The overall principle diagram of the automatic concentrating and scattering instrument provided for this embodiment, the automatic concentrating and scattering instrument includes a concentrating area, a transmission area and a diverging area, the concentrating area is provided with a concave reflector 1, and the transmission area is provided with a convex transmission area. The mirror 2 is provided with a flat mirror 5 and a convex reflector 4 in the diverging area.

[0050] The concave reflector 1 is a spherical concave reflector, such as Figure 7 shown. Convex mirror 2 is a spherical convex mirror, such as Figure 8 shown. The convex reflector 4 is a spherical convex reflector, and the structure of the diverging ...

Embodiment 3

[0054] In Embodiment 1 and Embodiment 2, in the light-gathering area, the concave reflector 1 needs to reflect the light irradiated from the sky to the ground so that it becomes a non-parallel light. Since the sun keeps moving with time during the day, the light is generally irradiated perpendicular to the ground. In the morning and evening, the light is slightly weaker, and our country is north of the equator, so in the east-west direction and the north-south direction The direction in which the sunlight is irradiated in one day is not the same, so this embodiment adjusts the angle of the concave reflector through the sunlight automatic regulator. Here, two schemes are divided to illustrate how to adjust the angle of the concave reflector 1 .

[0055] Option 1: East-West Sunlight

[0056] During a day, only half a day (11-14 hours) of sunlight can be irradiated on the automatic concentrator and scatterer, and the direction of sunlight is irradiated from east to west. Figur...

Abstract

The invention provides an automatic light gathering scatterometer. The automatic light gathering scatterometer comprises a light gathering zone, a transmission zone and a divergence zone, wherein the light gathering zone is provided with a concave reflecting mirror which reflects sunlight which perpendicularly irradiates from the above to the ground into unparallel light rays and gathers the light rays to the transmission zone; the transmission zone is provided with a convex transmitting mirror; the light rays gathered at the light gathering zone are allowed to pass through the convex transmitting mirror, parallel light sources are formed, the light sources irradiate a semi-underground garage / semi-basement after passing through a window of the semi-underground garage / semi-basement, and the light sources are reflected to the divergence zone; and the divergence zone is provided with a reflecting mirror surface used for reflecting the light rays reflected from the convex transmitting mirror, and a convex reflecting mirror used for reflecting the light rays reflected by the reflecting mirror surface to the ground in all directions. According to the automatic light gathering scatterometer, sunlight is gathered and then transferred into the semi-underground garage / semi-basement through mirror devices based on the principles that the light rays can be gathered through the concave reflecting mirror and a convex lens and the light sources can be diverged through the convex reflecting mirror, and the effects of transferring the light rays, strengthening brightness and saving energy are achieved.

Description

technical field [0001] The invention relates to an automatic condensing and scattering instrument, in particular to an automatic condensing and scattering instrument for semi-underground garages / semi-basements. Background technique [0002] At present, the semi-underground garage / semi-basement is a common building structure in industrial areas and commercial areas. Since the general semi-underground garage / semi-basement only has windows in the upper third of the floor, the light comes in through the windows. , due to insufficient light, the electric light can only be set 24 hours a day, which consumes a lot of electricity. [0003] In response to the country's call for "resource conservation", how to reduce the power consumption of the semi-underground garage / semi-basement under the premise of meeting the lighting requirements is a difficult problem that those skilled in the art are committed to solving. Contents of the invention [0004] The technical problem to be solve...
