Embodiment Construction

[0013] The center of the invention is to use the open light box cavity to quickly and flexibly replace the measured lamps, facilitate the detection process of the lighting effect of the lamps, and improve the applicability of the light box.

[0014] Attached below figure 1 , figure 2 The present invention is described in further detail:

[0015] A light box for observation of lighting effects according to the present invention includes a light box cavity 1, a light source support plate 5, a translucent diffusion plate 6, a shielding door 2 and a set of adjustment devices.

[0016] The front and top surfaces of the light box cavity 1 are open, and the openings on the top and front are convenient for replacing the light source in the cavity and installing light source starting equipment. In order to make the irradiated light evenly distributed, diffuse reflective material is applied on the surface of the inner cavity of the light box cavity 1. The diffuse reflective material ...

Abstract

The invention discloses a light box for observing lighting effects, which comprises a light box cavity, a light source support plate, a translucent diffusion plate, a blocking door and an adjustment device. The front and top surfaces of the light box cavity are open, and the adjustment device is arranged on the left and right sides of the inner cavity of the light box cavity. The middle part of the light source support plate is provided with a light source opening for irradiation, and the light source support plate and the diffusion plate are respectively connected to the adjustment device. On the upper side, the shielding door is installed at the position close to the upper side of the front opening of the light box cavity. Its structural design facilitates the replacement and installation of the lamps to be tested, and does not impose any restrictions on the size of the lamps to be tested, avoiding the influence of the light source on the observation process of the lower light source observation area after it is transmitted. At the same time, by adjusting the light source support plate and diffusion plate It can also meet the adjustment needs of different light source irradiation intensity, and realize the observation of light box lighting effects of different types of lamps.

Description

technical field [0001] The invention relates to a light box, in particular to a light box for observation of lighting effect which is flexible in use, easy to adjust and replace, and belongs to the field of lamp test equipment. Background technique [0002] In the research and development of lighting fixtures, the lighting effect of the lighting source and the impact on the comfort of the human eye are important indicators for the assessment of the lighting, such as common color temperature, color rendering index, color coordinates, etc., as well as in related human visual experiments. It needs to be measured by observing the actual lighting effect with human eyes. In reality, in order to control the environmental variables in the test, the lighting environment is usually limited in a light box, and the specific variables are changed by changing the light source or adjusting the light source parameters to realize the test and verification process. [0003] At present, the l...
