Technical Field

[0002] A light intensity simulation chamber is a device that can simulate environments with different light intensities. It is mainly used in scientific research, product testing and other fields. For example, in botanical research, different light intensities are simulated to study physiological processes such as photosynthesis and growth and development of plants. In material aging testing, by simulating different intensities of light, the durability and performance changes of materials (such as plastics, coatings, etc.) under light environment can be evaluated.
[0003] When using a lighting simulation box, it is necessary to simulate lighting to ensure that the light is close to the natural environment. However, existing lighting simulation boxes mostly use a single light source for simulation, so the range of spectra that can be simulated is small and cannot simulate the solar spectrum under different weather conditions (sunny, cloudy, partly cloudy).

The light source shaft is rotatably mounted on the inner side of the light source housing, and the light source base is fixedly sleeved on the light source shaft, so that the light source base can be rotated by rotating the light source shaft.
[0011] Specifically, the outer side of the light source base has three light source slots, and LED lights, halogen lamps and fluorescent lamps are respectively fixedly installed on the bottom inner wall of the three light source slots, so as to facilitate the replacement of different lamp groups according to needs.
[0012] Specifically, an adjusting gear is rotatably mounted on one inner wall of the light source housing, a motor slot is provided inside the light source housing, an adjusting servo motor is fixedly mounted on one inner wall of the motor slot, the output shaft of the adjusting servo motor is fixedly connected to the adjusting gear, a driven gear is fixedly sleeved on the light source shaft, and the driven gear meshes with the adjusting gear, so as to drive the driven gear to rotate through the adjusting gear.

The storage base 21 is snapped onto the inner side of the storage rack 5. Traction grooves are provided on both inner walls of the storage base 21. Limiting rods 6 are fixedly installed in both traction grooves. Corresponding clips 8 are slidably sleeved on both limiting rods 6. Traction springs 7 are sleeved on both limiting rods 6. The two ends of the two traction springs 7 are respectively connected to the corresponding clips 8, so that the two clips 8 can be moved closer to each other by the two traction springs 7.

The output shaft of the eccentric servo motor 11 is fixedly connected to the rotating shaft 9, and the rotating shaft 9 can be driven to rotate by the eccentric servo motor 11.
[0025] In this embodiment, the light source mechanism includes a light source shaft 16 and a light source base 17. The light source shaft 16 is rotatably mounted on the inner side of the light source housing 12, and the light source base 17 is fixedly sleeved on the light source shaft 16, so that the light source base 17 can be rotated by rotating the light source shaft 16.
[0026] In this embodiment, three light source slots are provided on the outer side of the light source base 17. LED lamps 18, halogen lamps 19 and fluorescent lamps 20 are respectively fixedly installed on the bottom inner walls of the three light source slots, so as to facilitate the replacement of different lamp groups according to needs.
[0027] In this embodiment, an adjusting gear 14 is rotatably mounted on one inner wall of the light source housing 12. A motor slot is provided inside the light source housing 12.

[0028] Working principle: During the light simulation experiment, the staff places the container with planted plants on the base 21 inside the shelf 5. Then, the eccentric servo motor 11 is activated via the control panel. The eccentric servo motor 11 drives the rotating shaft 9 to rotate, which in turn drives the eccentric block 10 to rotate. The rotation of the eccentric block 10 stops pressing on the two clamps 8. At this point, the two clamps 8 are pulled closer together by the traction force of the two traction springs 7, clamping the plant container. Then, according to the environment to be simulated, the staff activates the adjustment servo motor 13 via the control panel. The adjustment servo motor 13 drives the adjustment gear 14 to rotate, which in turn drives the... The driven gear 15 rotates, which in turn drives the light source shaft 16 to rotate. The rotation of the light source shaft 16 drives the light source base 17 to rotate, which in turn drives the halogen lamp 19, fluorescent lamp 20, and LED lamp 18 to rotate. By selecting the corresponding light source according to the spectrum of the required environment, a lighting environment that is close to reality can be simulated. This is very important for plant photobiology research and the testing of some materials with extremely high requirements for spectral accuracy (such as photovoltaic materials). Subsequently, the staff added an appropriate amount of water to the water storage tank 3 to ensure that the moisture content of the air inside the equipment was suitable. After starting the circulating fan 4 through the control panel, the sealing door 2 was closed to conduct the simulation test.
[0029] The technological advancements of this invention compared to existing technologies are as follows: By adjusting and replacing the halogen tungsten lamp 19, fluorescent lamp 20, and LED lamp 18 through the light source mechanism, the range of the simulated spectrum can be expanded, enabling more accurate simulation of the spectrum in the natural environment. This greatly improves the applicability of the equipment. Furthermore, the shelf 5 can be adjusted to accommodate plant containers of different sizes, increasing the applicability of the equipment.
