Solar reflector for improving the shade of a building

This invention relates to solar installations, and more particularly to a solar reflector for improving the illuminating of a building's shade.

Background technique ,

In ancient and modern China and foreign countries, no matter where in the corner of the earth, the houses inhabited by human beings have different aspects of the sun and the shade. The sunny houses are warm and bright, people are happy and comfortable; the shaded houses are gloomy and cool, and they are dull all year round. Living and working in a dark room for a long time not only brings a lot of pain and trouble to the people in the room, but even brings people sickness. Buyers will be reluctant to ask because there are too many rooms in the house. It is difficult for sellers to sell because they are shaggy houses.

At present, there are many products that use solar lighting at home and abroad, but most of them convert solar energy into electrical energy, and then use it for lighting. These products all need to be illuminated by solar cells. They all have obvious defects: First, high cost and short life. Second, it is impossible to illuminate the entire target of the entire high-rise building. The Department of Electronics, Beijing Agricultural University, invented a solar reflective lighting device that attempts to directly use the principle of solar reflection, but because of its complex and unreasonable design, it can only illuminate small-area targets. It is used to increase the temperature of a large range of houses in winter.

The solar reflector of the present invention for improving the shading of a building includes two parts: a reflecting means for collecting light and a light sensor mounted on the side of the backlight of the building. Reflector is important for solar reflectors The component of which is to reflect sunlight into the target area. In different seasons, the mirrors are available in different materials and reasonable sizes for different houses. For example, mirrors can be designed as double-sided, made of different materials, depending on the needs of winter and summer. In winter, materials with high reflectivity and low heat absorption can be selected to maximize lighting and room temperature. In the summer, soft and heat-absorbing materials can be used to improve the lighting without increasing the temperature of the room. The mirror is designed to be foldable. When it is hot, the mirror can be partially folded to reduce the reflection area. The telescopic arm is used to adjust the angle of the mirror up and down to ensure that the reflected light does not leave the projecting target when moving up and down due to the change of the sun position. The working principle is to adjust the vertical angle of the mirror by pushing and pulling the telescopic arm back and forth. The telescopic arm can be mounted on the upper end of the reflector or on the lower end. It can also be mounted up and down to shorten the design length of the telescopic arm.

The following describes the operation of the four light sensors of the solar reflector.

The main sensor 8 mounted on the stand 7 is a signal source for starting or stopping operation. Every morning, when the sun is just rising, the main sensor detects the reflection conditions according to the design parameters. When the reflection condition reaches the design parameters, the main sensor immediately signals the microprocessor. Immediately after the microprocessor receives the signal, the power is turned on. When the sun is obscured by clouds or the sun is falling and the reflection conditions are insufficient, the main sensor immediately signals the microprocessor, and the microprocessor then turns off the power.

The side light sensor 12 or 13 is mounted on the east or west side of the boundary of the illuminated portion of the building's shade, and its function is to instruct the reflector to laterally adjust the angle of reflection so that the reflected light does not leave the reflected target in the lateral range. When the side light sensor 12 or 13 is installed on the west side of the boundary of the illuminated part of the building, in the morning, whenever the main sensor instructs the microprocessor to start working, the mirror starts to turn to the right (the opposite is true in the southern hemisphere) until the reflection Light is projected onto the side light sensor. When the side light sensor senses the reflected light, it immediately sends a signal to the microprocessor, and the microprocessor then instructs the mirror to stop rotating. As the sun moves westward, the reflected light on the surface of the building slowly moves eastward as the sun moves westward. When the reflected light leaves the side light sensor, the side light sensor immediately signals the microprocessor, and the microprocessor immediately controls the mirror to rotate to the right by one scale (the southern hemisphere is just the opposite). As the angle of reflection changes, the reflected light on the surface of the building moves westward in the opposite direction and is re-projected onto the side light sensor. When the side light sensor re-sensing the reflected light, it immediately signals the microprocessor, and the microprocessor then instructs the mirror to stop rotating. The above operation is repeated when the reflected light leaves the side light sensor again. When the sun is falling and the mirror is rotated to the maximum point, the microprocessor controls the mirror back again. Go to the starting point and wait for the sun to rise again the next day.

When the side light sensor 12 or 13 is mounted on the east side of the boundary of the illuminated part of the building, in the morning, whenever the reflector starts to work, the mirror rotates from right to left (the opposite is true in the southern hemisphere) until the reflected light is projected. To the side light sensor. When the side light sensor senses the reflected light, it immediately sends a signal to the microprocessor, and the microprocessor then instructs the mirror to rotate a scale from left to right in the opposite direction (the opposite is true in the southern hemisphere). The reflected light then leaves the side light sensor and the rotation stops immediately. As the sun moves westward, the reflected light on the surface of the building slowly moves eastward as the sun moves westward and is re-projected onto the sidelight sensor. When the side light sensor re-sensing the reflected light, it immediately signals the microprocessor, and the microprocessor then instructs the mirror to rotate to the right by a scale (the southern hemisphere is exactly opposite). When the side light sensor senses the reflected light again, the above operation is repeated. When the sun sets, the mirror stops rotating.

The upper and lower light sensors 10 and 11 are respectively installed at the upper end and the bottom of the boundary of the illuminated portion of the building, and the function is to instruct the reflector to adjust the reflection angle longitudinally so that the reflected light does not leave the reflection target in the upper and lower ranges.

If the telescopic arm is mounted on the upper end of the reflector, when the sun rises, the reflected light on the surface of the building will slowly move down as the position of the sun increases. When the reflected light leaves the glazing sensor, the glazing sensor immediately signals the microprocessor, and the microprocessor immediately controls the telescopic arm to pull back, and the reflected light then moves up and returns to the original position. When the glazing sensor senses the reflected light, it immediately signals the microprocessor, and the microprocessor then commands the telescopic arm to stop pulling. The above operation is repeated when the reflected light moves down again and leaves the glazing sensor. The lower light sensor works in the same way as the light sensor. The only difference is that as the sun's height decreases, the reflected light is continuously adjusted downward in the opposite direction. If the telescopic arm is mounted at the lower end of the reflector, the push-pull direction of the lower telescopic arm is exactly opposite to the upper telescopic arm when the sun's height changes.

By continuously and horizontally adjusting the angle of reflection, the reflector allows the reflected light to remain in the target area during the day, regardless of the position of the sun, thus ensuring that the reflector design goal is achieved.

The reflected light that occurs when multiple reflectors are used at the same time interfere with each other, and the morning and evening sunlight can interfere with the reflector:

When multiple reflectors are used at the same time, reflected light will overlap each other, causing it to be installed on the back of the building. The light sensor on the light side cannot be distinguished, and which reflected light is from the reflector connected to it, resulting in the reflector not working properly. Since most buildings are not completely north and south, this will cause morning and evening sunlight to interfere with the reflector, and the result will also cause the reflector to not work properly. The solution to this problem is to use a thin tube of about ten centimeters in length on the light sensor mounted on the back side of the building, so that the optical sensor is fastened at one end of the nozzle and the other end of the nozzle is facing Connected reflectors. Since the light travels straight, the light sensor can only receive the reflected light from the reflector connected to it, and the reflected light or sunlight of other reflectors cannot be received due to the angle tilt. In this way, the mutual interference between the reflectors and the interference of the sun and the sun in the morning and evening can be solved.

The features of the invention are:

1) Because the cost of the solar reflector is low, the price is not high, and it is a one-time investment, which is easy for consumers to accept.

2) The solar reflector can save electricity for lighting and reduce heating costs and energy for residents in winter.

3) Sunlight reflectors allow the average brightness of the shaded room to exceed the sunny room. This is because, even in a sunny room, only around noon, the sun can shine into the house at a large angle, and most of the time, it can only be illuminated indoors on the corner or balcony. The sun reflector always illuminates the house at an optional, fixed angle. Reflectors with ordinary glass have a solar reflectance of about 90%. Moreover, when multiple mirrors illuminate the same target at the same time, the brightness of the reflected light is multiplied, making it possible for the shaded room to have an average brightness of more than the sun. .

4) The sun reflector can make the shabby house appreciate. Due to the difference in illumination between the north and south houses, even the same negative and sunny houses are far from the value. Sunlight reflectors reduce the difference between the north and south of the building, and even allow the light of the shady houses to exceed the sun's surface on average, so that the old and the old houses can be appreciably appreciated in value.

5) In addition to being used to improve the shading of buildings, solar reflectors can improve crop photosynthetic quality in agricultural production. It is well known that photosynthesis is extremely important for the growth of crops, and improving the photosynthesis of crops will inevitably increase the quality of crops and the yield per unit area. By reflecting sunlight, the solar reflector can carry out large-area, long-time supplemental light irradiation from the shade to the farmland, creating the best external conditions for improving the photosynthesis of crops, thereby promoting the quality of crops and the yield per unit area. effect. 6) The well-designed reflector will become a beautiful landscape on the building. Since the mirror is mainly made of glass, and the glass itself is decorative to the building, the installation of the reflector does not damage the overall appearance of the building. If the reflector is beautifully designed and integrated with the characteristics of the building itself, it will make the building more distinctive.

7) Sunlight reflectors offer new options for people who love the sun bath. People who often like to bathe outdoors in the sun often suffer from a variety of diseases due to prolonged exposure to intense sunlight. The light reflected by the solar reflector is relatively soft, and can basically filter out the ultraviolet rays harmful to human skin and eyes in the sunlight, thus greatly reducing people suffering from various skin diseases and eye diseases due to the sun bath. possibility. Bathing in the sun reflects light and may become a big fashion in people's lives in the future. .

8) The use of a solar reflector does not cause light pollution problems. The so-called light pollution mainly refers to the distracting light of the eyes and the harmful light to the human body, which brings people troubles and discomfort. The reflected light of the solar reflector is controlled, rational and orderly, and illuminated by natural light. It is different from the glare of the glare, not the harmful light.

Since the reflector is installed, the reflected light can be obliquely entered into the window of the building at a reasonable angle, so that the person in the room can not easily see the mirror when it is outside the flat window, so that the eye can be greatly reduced. The possibility of dispelling concerns about the light pollution of solar reflectors.

In fact, the degree of stimulation that the reflected light of the solar reflector brings to the human eye cannot be compared with the sunlight. Since the person in the room can receive the sunlight, there is no reason to say that the reflected light cannot be received. As long as people avoid their eyes, and don't consciously stare at the mirror, as if they don't stare at the sun, the so-called light pollution problem is not a problem at all.

9) The solar reflector can effectively adjust the feng shui of the house. The so-called feng shui, that is, yin and yang feng shui, the Yin yin yin house is a tomb, and the Yang yin yang house is a house. The Yin House is dominated by the darkness, and the Yang House is governed by the Light. The yin house can't see the light, but when it sees the light, the feng shui is bad. The yang house cannot be dull, and the feng shui is damaged if there is no light. Mr. Shao Weihua, the contemporary forecasting master, mentioned in his book “The Lectures on Zhouyi Predictive Lectures” that the feng shui of Yangzhai must have four elements: “qi, light, mountain, water”, and light is one of the four elements. It is extremely important to see sufficient light for the feng shui of Yangzhai.

As everyone knows, people who live and work in dark houses that don't see the sun for a long time are not only depressed, but also prone to illness. But very few people understand that this is caused by poor housing feng shui, and One of the direct causes of poor feng shui is the lack of light, causing yin and evil, germs and other harmful organisms to take advantage of. The sun reflector provides sufficient light for the room, allowing the yang to retire and effectively improve the house feng shui.

The "Yellow Emperor's House" records: "Home, the person's foundation, people take the house as their home, Ju Ruan, the family Changji, if uneasy, that is, the door family decline." "People stand for the house, the house is inhabited, the house is supported, and the heavens and the earth." Also said: "Good land, Miao Wang Sheng, Zhai Ji, people prosperous." Mencius also said: "You can move, you can move, and you can live in a big room." The ancient sages regard the relationship between houses and people as important. It can be seen that the quality of houses and feng shui will indeed affect the physical and mental health of those who live and work in them, and will also affect the success or failure of people, families, and future generations. It can be said that the evil and the good fortune. Sunlight reflectors help to improve the feng shui of the house. It is called "feng shui Mirror", which will play a positive role in creating a high quality life for people.
