Description

Reflecting device for reflecting sunlight outside window to indoor

Technical Field

The present invention relates to lighting devices, and more particularly, to a light reflecting device for reflecting sunlight outside a window into a room.

Background

Generally, in sunny summer, the intensity of outdoor sunlight is about 6-10 ten thousand Lux from 10 am to 3 pm every day, the general rainy day can reach 5000Lux, the illumination of indoor lighting is only 100-.

Stimulation of serotonin secretion requires approximately 2500-. The concentration of serotonin is the most important indicator of depression. In addition to stimulating serotonin production, sunlight can also stimulate dopamine secretion. After being irradiated by intense light, the rod cells also release dopamine on the retina, and the retinal dopamine is a key signal for activities such as eyeball growth and development, cell death and the like.

When retinal dopamine drops below a certain level, the axis of the eye begins to elongate. The continuous elongation of the eye axis corresponds to the continuous increase of the myopic degree. Under the intensity of outdoor light, the signal that the axis of the eye is continuously elongated disappears along with the increase of the concentration of dopamine, so that the person cannot be myopic, or the myopic degree cannot be continuously increased.

Currently, the incidence of myopia in teenagers, especially in long-term near-distance eye users, is high, mainly due to insufficient illumination intensity of indoor environment. One very important means of preventing myopia is to ensure sufficient light intensity in the room.

Learning and work sites include classrooms, study rooms, conference rooms, offices, libraries, dormitories, auditoriums, and the like.

At present, the light intensity of indoor lighting lamps is weak, and the unfavorable luminous environment can cause injury to eyes, thereby causing myopia. The time threshold initially found was 2 hours of outdoor exercise per day, and as long as this threshold was exceeded, the incidence of myopia was low.

It is seen that it is necessary to transmit a large amount of sunlight of 1 to 10 million Lux free of charge to the interior of a room to ensure that the light intensity inside the room can be compared with that outside the window within a few hours. It is also particularly important that the sunlight is truly full spectrum and stroboflash free.

Therefore, the light reflecting device for reflecting sunlight outside the window to the indoor space has very important practical significance.

Detailed Description

Example 1

This embodiment 1 describes a light reflecting device for reflecting sunlight outside a window into a room.

The reflecting device comprises a multilayer reflecting mirror array and a reflecting angle adjusting mechanism, wherein as shown in figure 1, the reflecting mirror array is three layers, and each layer of reflecting mirror array 1 is sequentially arranged from top to bottom to form an upper, middle and lower three-layer reflecting structure.

Each layer of reflector array 1 is arranged at an outdoor window, so that sunlight can be conveniently reflected to an indoor ceiling.

Specifically, each layer of the mirror array 1 is responsible for reflecting sunlight to a designated area of the indoor ceiling, for example, the left reflecting area, the middle reflecting area, and the right reflecting area shown in fig. 1.

Through the combination of the reflector arrays 1, most areas of the ceiling can obtain reflected sunlight.

In the present embodiment, the mirror array 1 is, for example, a plane mirror, that is, the reflecting surface is a plane. Of course, the mirror array 1 in this embodiment 1 preferably uses a convex mirror, i.e. the upward reflecting surface is convex, to increase the reflecting area.

In the present embodiment 1, the ceiling board is preferably a white wall, and the surface thereof is a diffuse reflection surface for efficiently reflecting sunlight to various places in the room. The sunlight reflected from the outside of the window irradiates the ceiling, and then irradiates everywhere indoors through diffuse reflection.

And the reflection angle adjusting mechanism is used for independently adjusting the reflection angle of each layer of reflector array 1, and based on the reflection angle adjusting mechanism, each layer of reflector array is respectively provided with one set of reflection angle adjusting mechanism, and the mechanisms are mutually independent.

When the irradiation angle of the sunlight changes, the reflection angle of the corresponding reflector array 1 is adjusted by each reflection angle adjusting mechanism, so that the reflected sunlight can be better received indoors (for example, on a table top in a classroom).

The reflection angle adjusting mechanism in this embodiment 1 can be used in cooperation with the illumination sensor described below, so as to automatically adjust the reflection angle of each layer of the mirror array 1 according to the illumination intensity at each location in a room.

The mirror array 1 is made of a chrome-plated or nickel-plated iron plate, stainless steel plate, or aluminum alloy plate material.

Wherein, the upward surface of the reflector array 1 is a polished surface. The stainless steel plate or the aluminum alloy plate has better corrosion resistance, and the corrosion resistance and the light reflecting performance are obviously enhanced after the iron plate or the stainless steel plate is protected by a nickel coating or a chromium coating.

The reflector array 1 made of the materials can achieve a good reflection effect, and the thickness of the metal plate is designed to be 0.1-5 mm.

Certainly, the reflector array 1 may also be made of a surface-hardened Polycarbonate (PC) or acrylic organic glass Plate (PMMA), and the lower surface of the reflector array 1 is provided with a vacuum aluminum-plated layer, which is then protected by a plastic film or a paint.

The thickness of the organic glass plate in the embodiment is designed to be 0.1-5 mm.

The polycarbonate or acrylic organic glass plate has the advantages of low density, strong corrosion resistance and strong explosion-proof capability.

The reflectivity of the vacuum aluminum coating is as high as 97%, and the vacuum aluminum coating is favorable for reflecting most sunlight indoors.

Of course, the reflector array 1 may also be made of tempered inorganic glass plate, and the tempered inorganic glass plate also has higher strength.

The thickness of the inorganic glass plate in this example is designed to be 0.1 to 5 mm.

The lower surface of the reflector array 1 is also provided with a vacuum aluminum-plated layer, and the vacuum aluminum-plated layer is protected by a plastic film or a lacquer surface.

In addition, the light reflecting device of the present embodiment 1 further includes a controller 2 and a light intensity sensor 3, as shown in fig. 4. The reflection angle adjusting mechanism 4 and the illuminance sensor 3 are connected with the controller 2 through signal cables respectively.

The illuminance sensor 3 is installed indoors, and is used for sensing and feeding back indoor light intensity values in real time.

In this embodiment, there may be one illuminance sensor 3, but there may also be a plurality of (e.g. 3) illuminance sensors, and the illuminance sensors are respectively located at different positions in the room, for example, one illuminance sensor 3 is respectively disposed in three reflection areas of the ceiling board in fig. 1.

The light intensity value of each indoor place can be accurately collected through the light intensity sensor 3.

When the light intensity in the room is weak, the light intensity is automatically fed back to the controller 2, and the controller 2 controls the action of all or part of the reflection angle adjusting mechanisms to adjust the reflection angle of each layer of the mirror array 1 to the optimal reflection angle.

Similarly, when the indoor light intensity is stronger overall or locally stronger, the controller 2 can also be fed back automatically, and the controller 2 controls the action of all or part of the reflection angle adjusting mechanism, so that the indoor light intensity is weakened.

It can be seen that the illumination intensity sensor 3 is matched with the reflection angle adjusting mechanism, so that the reflection angles of the reflector arrays 1 in each layer can be adjusted in a self-adaptive manner according to the indoor illumination intensity, and the automation degree is high.

The controller 2 is preferably a single chip microcomputer controller, and the illuminance sensor 3 can be a currently mature light intensity sensing device.

As shown in fig. 2 and 3, the present embodiment 1 provides a preferable reflection angle adjustment mechanism.

The mechanism comprises a mirror array support 5, a mounting support 6 and drive means.

The reflector array holder 5 preferably has a square frame structure, and the reflector array 1 is mounted on the reflector array holder 5.

As shown in FIG. 2, each layer of the mirror array 1 can be composed of a plurality of square mirror units, and this structure is suitable for the situation of large window size, and is convenient for installing, maintaining and replacing the mirror array 1.

Of course, in the case where the window size is not too large, a mirror of a monolithic structure may be employed for each layer of the mirror array 1.

A mounting shaft 7 is provided at the middle position of one set of opposite sides of the mirror array support 5, respectively.

The number of the mounting brackets 6 is two, and each mounting bracket 6 is correspondingly located on the side of one mounting shaft 7, for example, one mounting bracket 6 is located at the mounting shaft 7 on the left side, and the other mounting bracket 6 is located at the mounting shaft 7 on the right side.

Each mounting bracket 6 is vertically mounted on a wall 8 at the side of the outdoor window. All set up the dead eye on every installing support 6 and install bearing 9, each installation axle 7 is installed respectively on the bearing 9 of corresponding side.

The driving component is located at the left mounting shaft 7 (of course, it may also be located at the right mounting shaft 7), is connected to the mounting shaft 7 at the side, and is used to drive the mounting shaft 7 to rotate, so as to adjust the angle of the mirror array 1.

In the embodiment 1, a belt driving member may be used as the driving member, but a gear driving member is preferably used.

As shown in fig. 3, the gear driving part includes a driving motor 10, a driving gear 11, and a driven gear 12. Wherein, the driving motor 10 is installed on the wall 8 of the outdoor window side through the motor bracket 13.

A driving gear 11 is attached to an output shaft of the driving motor 10, and a driven gear 12 is attached to the mounting shaft 7.

The driving gear 11 and the driven gear 12 are engaged with each other.

After the driving motor 10 is turned on, the driving gear 11 is driven to rotate, so as to drive the driven gear 12 to rotate, and simultaneously drive the mounting shaft 7 to rotate, so as to drive the whole body formed by the reflector array bracket 5 and the reflector array 1 to perform angle adjustment.

Through setting up three group reflection angle guiding mechanism more than, do benefit to the realization and independently adjust three-layer reflector array 1 angle. Of course, the number of the mirror arrays 1 in this embodiment 1 is not limited to three, but may be one layer, two layers, four layers or more.

When the reflector array 1 is not needed to work, the shutter reflector arrays 1 on each layer can be contracted through the reflection angle adjusting mechanism and then rotated to the position close to the wall body 8.

By the design, each layer of reflector array 1 can be protected from being damaged by severe weather such as storm and rainstorm.

This embodiment 1 is through reflex reflector, with direct reflection of sunshine outside the window to indoor ceiling, then further scatters sunshine everywhere indoor through the ceiling to strengthen indoor luminous intensity, reduce the incidence of myopia.

In 3-5 hours near noon, the light reflection device in the embodiment 1 can better reflect sunlight to the indoor, and the light intensity reflected by the indoor ceiling can reach 10000Lux of 2000-.

The sunlight is full spectrum and has no stroboflash, which is beneficial to the protection of eyes.

In addition, if severe weather, such as strong wind, heavy rain or ice and snow weather, and when the light reflecting device is not used at night, the reflector array can be folded through the reflection angle adjusting mechanism so as to reduce the damage of the reflector array.

The reflector described in this embodiment 1 can be applied to learning and working places, such as classrooms, study rooms, conference rooms, offices, libraries, dormitories, auditoriums, and the like, but is not limited thereto.
