Description of the Invention: [Technical Field] The present invention relates to a concentrator, and more particularly to a fixed concentrator. [Prior Art] Due to the development of science and technology, people's demand for energy continues to increase. However, due to the limited resources of the earth, energy prices are rising, and all sectors are turning to renewable energy. The inexhaustible solar energy seems to bring Come-line hopes that solar energy is clean and zero pollution, and it will not consume other earth resources or cause the global warming effect. It is worthy of promotion in areas with sufficient sunshine. In addition, the sunlight has excellent color rendering properties, providing the most natural visual effects, and is very suitable for use in the room (four), which can be used to rectify the problem that the modern house still has to be turned on due to poor room lighting. In an era when modern people are paying more and more attention to the living environment, the use of solar lighting systems to introduce sunlight into indoor light-guided buildings for lighting has gradually gained favor. Generally, the solar lighting system is mainly divided into three parts: light collection, light transmission, Φ and light divergence according to the functions of various components. The first part is used to collect light, commonly known as the sun concentrator (four) anal concentmt. !·) 'The most important technical problem is the efficiency of the light collection; the second part is used to transmit the miscellaneous items of the job, the lightguidingdeviee, such as the high-quality light-conducting device (4) During the transmission process, the third component is used to diverge the light transmitted from the light-conducting device for illumination. The lighting system is known as the system, and the uniformity of the light is the focus of design considerations. This case focuses on the riding design of the Sun (four) H. Lai Shang, by the financial system - the angle of the sun's light incident to the set of the first time in each day of the year is not fixed, in order to improve the collection of light 201026998 H Guancai, Lai Ziqi, the fiber set, work, in When the time _ Qing Jia scales (four) grades to collect the purpose of solar energy. However, the current tracking system is very expensive and requires power supply from the power system. Therefore, it is necessary to develop a fixed type of concentrator to collect sunlight in order not to track the sun or use the power system. SUMMARY OF THE INVENTION The present invention is directed to providing a reticle concentrator. Another object of the present invention is to provide a fixed concentrator using a compound parabolic mirror ((C) parabolic concentrator, CPC) as a light collecting element. The purpose of the P of the present invention is to provide a fixed concentrator that can change the angle of incidence of sunlight in the seasons of the special shots and (iv) seasons. Another object of the present invention is to provide a concentrating concentrator that is inexpensive and has a high resolution. SUMMARY OF THE INVENTION A third object of the present invention is to provide a concentrating concentrator that can be finer than a room. In the above object of the invention of the present invention, the fixed concentrator of the present invention comprises a first holding mirror group, a second parabolic mirror group, and a chamber. The first object mirror group has two mirror faces that face each other and are oriented in the east-west direction. The second parabolic mirror group has two parabolic mirrors that are mirror-opposed and arranged in a north-south direction. The first parabolic mirror group and the second parabolic mirror group form a chamber having an entrance plane and an exit plane, and the light enters the chamber through the entrance plane, and is reflected by each parabolic mirror and directly enters the light that is not reflected by each parabolic mirror. The exit plane is shot and collected, and the first parabolic mirror set in the east-west direction is designed to match the incident angle of sunlight caused by the sun running from east to west during the day, and the second parabolic mirror set in the north-south direction. Cooperate with a 4 201026998 • Designed to change the angle of incidence of sunlight caused by the sun's south or north. Aspects of the invention 'fixed (four) n-parabolic mirror minus second parabolic mirror group are bribe-type mirrors, wherein (1) the area of the population plane is larger than the area of the exit plane; (7) some light passes through one of the parabolic mirrors After the parabolic mirror reflects once, it will travel to the exit plane. Some green will directly it π flat φ silk through each transmission surface; (3) the focus of each parabolic mirror falls on the tow surface that is opposite to it. The bottom of the mirror. The financial model of the present invention can be used to touch the maximum ray of the person to shoot the light. The installation location is different from the point of view. The first _ mirror set in the east-west direction can receive the east-west component. The maximum angle of incidence of the light is determined according to the time range in which the light is collected during the day of the desired location, and the elevation angle and azimuth angle of the sun at two endpoints; the second parabolic mirror set in the north-south direction The range of the maximum angle of incidence of the light that can receive the north-south component is determined by the orbital plane of the sun for each season at the location where it is to be installed. The fixed concentrator of the present invention achieves a higher light collection efficiency when it is tilted and can be set in a certain season than when it is not inclined. ® Since the fixed concentrator of the present invention is different from the concentrator that requires an expensive sun-tracking system, the concentrator has the advantage of low cost and is more energy-saving because it does not need to be driven by a power system. Environmental protection. In addition, the present invention can efficiently collect sunlight by appropriately designing a fixed concentrator to receive a maximum angular range of incident light. The present invention is well suited for use in the field of indoor lighting, which can solve the problem of dim interiors during daytime due to poor architectural design. [Embodiment] Referring to Fig. 1, the present invention uses a compound parabolic mirror to collect sunlight. In 1966, a compound parabolic mirror has been proposed for the development of non-imaging optics (10)^ such as %^^^%. 201026998 'As shown in Figure 1 'The composite parabolic mirror consists of two parabolic mirrors 10, 11 whose mirror faces are arranged facing each other to collect light over an angular range, from the entrance plane (entr^ plane) 15 Light entering through the parabolic mirror and directly entering without being reflected by each parabolic mirror is emitted by an exit plane 16 and collected. An ideal composite parabolic mirror has an entrance plane 15 that is larger than the exit plane 16' or an aperture at the entrance of the light that is larger than the aperture at the exit of the light, and some of which are reflected by the parabolic mirror once and then exited by the exit plane 16, some The light will enter the exit plane 16 directly without being reflected by the parabolic mirrors, and the focus of the parabolic mirror 10 will fall at the bottom of the parabolic mirror 11 (as at point d in Figure 1), and the focus of the parabolic mirror u will fall on Drag the bottom of the object mirror 10 (as at point c in Figure 1). For example, in the light plane 19, the light rays from the points A, B, and C are reflected at the points a, b, and e of the parabolic mirror 10, respectively, and are focused on the bottom of the parabolic mirror 11 at the point d. At this time, the angle θ formed by the incident ray with the vertical axis 18 perpendicular to the entrance plane 15 and the exit plane 16 (: is half of the maximum angular range that the compound parabolic mirror can receive the incident ray. The incident ray is perpendicular to the vertical axis 18 If the angle is less than 0C, the light will be reflected by the parabolic mirror 10 or the parabolic mirror u once or directly. The light reflected by the parabolic mirror 1〇 or the parabolic mirror U will be emitted at the exit plane 16 and collected. The figure shows a schematic diagram of a fixed concentrator designed to adapt to different solar light incident angles throughout the year and the day. As shown in Fig. 2, the fixed concentrator of the present invention comprises a first a parabolic mirror group 20 and a second parabolic mirror group 21. The first parabolic mirror group 20 and the second parabolic mirror group 21 each have two mirror-facing parabolic mirrors, and the two parabolic mirror groups 20, 21 surround the valley to 24 'To accommodate the light before and after reflection by each of the mirrors. The chamber 24 has an inlet plane 25 and an exit plane 26, and the light 201026998 passes through one of them. The object mirror reversal plane 26 is emitted and collected by the entrance plane 25 into the chamber 24' after entering the chamber 24, and the light that is directly incident without being reflected by each parabolic mirror is set by the following system according to the following principles: (2) Some light passes through. In order to achieve better light collection efficiency, the fixed light collector of the present invention is formed. (1) The area of the entrance plane 25 is larger than the area of the exit plane 26, which is - parabolic sulfur reflection - Read and travel to the σ plane 26, some light will enter directly

For example, the first parabolic mirror 'group 20 towel, the focus of a parabolic mirror is located at point e in Fig. 2, and the other - parabolic mirror _ is in the plane with the e阙 plane, opposite to the bottom of the parabolic mirror; Similarly, in the second parabolic mirror group 21, the focus of a parabolic mirror is located at point f as in Fig. 2, and the focus of the parabolic mirror is located on the same plane as point f, opposite to the bottom of the parabolic mirror. The m-shaped light-collecting wipes of the present invention have the two-object mirrors which are provided in the east-west direction, and the incident angle of the sunlight caused by the sun running from east to west; The two-sided mirror mirror of the second parabolic mirror group 21 is arranged in a north-south direction to match the sun-light angle of the sun to the south or north of the four seasons, as shown in Fig. 2' The angle between the east-west component of the human beam and the vertical axis 28 perpendicular to the human π plane 25 and the exit plane is one (four) representing the maximum angular extent of the incident light of the 集 stationary collector n of the present invention that can receive the east-west component. Half; the angle eN-s ' formed by the component of the incident ray in the north-south direction and the vertical axis 28 represents half of the maximum angular range of the incident light of the north-south component of the stationary concentrator of the present invention. The angle between the east-west and north-south component of the incident ray and the vertical axis 28 is smaller than eE_w, Θν-s, respectively. The light reflected by the parabolic mirror or directly entering without the parabolic mirror will be emitted at the exit plane 26 Collect it up. 7 201026998 Due to the different latitude and longitude of each place on the earth, the time of sunrise and sunset in the day and the trajectory of the sun passing through the sky in different seasons are different, so the fixed concentrator of the present invention can receive incident light. Half of the maximum angular range (eE_w, eNs) will vary depending on where the installation is made. According to the installation location, the present invention utilizes the distribution of the average irradiance of the sunlight per hour in the season to determine the time range for the light collection during the day, and utilizes the sun in the sky throughout the year. The track determines the maximum angular extent of the desired incident light. Take Taipei, Taiwan (East, 121., latitude 25.5.), for example, the Central Meteorological Administration first obtains the average irradiance of the sun in each season. For indoor lighting applications, these materials must be converted first. The average illuminance is because the human eye of the wavelength other than visible light is invisible. According to the statistics, the average illuminance distribution curve per hour is almost symmetrical, and the average illuminance at noon is the maximum value. The average illuminance rises rapidly as the sun rises, about half of the maximum at nine in the morning. By noon, the average illuminance ® reached a maximum value, and after noon the average illuminance began to decrease. At about three o'clock in the afternoon, it was about half of the maximum, and after three o'clock in the afternoon, the level of dries quickly decreased until sunset. In the morning, the average acidity of the three thorns in the afternoon is at most - half or more. This is also the most important need for the office or school to strengthen the room (four), so that in the case of Taipei, you can The time range for light collection is set in the time range from 9:00 am to 3:00 pm. See section 3 ® 'This figure shows the sun's trajectory in the sky in Taipei. The summer solstice line represents the trajectory of the sun during the summer solstice. The winter solstice line represents the trajectory of the sun on the winter solstice. The sun's trajectory is almost the same during the vernal equinox and the autumn equinox.
