Problems solved by technology

[0003] This method is only suitable for evaluating the light-guiding ability of the light-guiding film in the above-mentioned patent; and it uses the intensity of light received at various angles to evaluate its refraction light-guiding ability. This evaluation method is difficult to compare the difference in light-guiding performance of different products; in addition, the method The method is not combined with the actual application of the building; this method cannot reflect the contribution to the reduction of lighting energy consumption and the improvement of illumination uniformity, lacks intuitive detection data, and is difficult to be accepted by architects

Embodiment Construction

[0033] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0034] The invention provides a light guide effect detection device for architectural light guide film and its products, such as figure 1 As shown, including a metering box 2 and a light source 1, the light beam used in the present invention is parallel light, and the light source should be a light source that can produce parallel light beams. The metering box 2 is made of an opaque plate, preferably a thin plate, and the metering box 2 The inner surface of the bottom wall is gray, the bottom wall itself can be gray, or the inner surface of the bottom wall can be coated with gray paint. The gray bottom wall is used to simulate the color of the room floor, such as cement floor, etc., and the inside of the side wall of the metering box The surface and the ...

Abstract

The invention discloses a guide light effect detection device and method for building light guide films and products thereof and belongs to the field of building light guide film detection. The device comprises a metering box and a light source, the metering box is made of a light-proof sheet, the inner surface of the bottom wall of the metering box is gray, the inner surface of the side wall and the inner surface of the top wall of the metering box are white, an installation window used for installing light guide film test piece is formed in the side wall of the metering box, at least two luminous sensors are evenly distributed on the inner surface of the bottom wall of the metering box, and incandescent light bulbs are arranged on the inner surface of the top wall of the metering box. By the arrangement, difference of light guide performance of different products is easily compared, and high operability is achieved; use conditions of the building light guide films and the products thereof under the actual working condition can be simulated; comprehensive detection data are achieved, and the device and method is easy to be accepted by architects.

Description

technical field [0001] The invention relates to the field of architectural light-guiding film detection, in particular to a light-guiding effect detection device and detection method for architectural light-guiding films and products thereof. Background technique [0002] Architectural light-guiding film and its products (window group, venetian blind, etc.) are a new type of architectural functional material, which can refract the sunlight incident into the room to the ceiling of the room, saving lighting energy consumption and improving indoor lighting uniformity. At present, for its light guide detection method, a simple device is mentioned in the patent "window group and its light guide film" (201110052379.7). By arranging photosensitive elements at 180° on the transmission side of the film, the light received at each angle is collected. The intensity of the light is evaluated to evaluate its refraction light guiding ability. [0003] This method is only suitable for eva...
