[0030] The specific usage and function of this embodiment are as follows: It mainly includes a 500mm integrating sphere, an integrating sphere light-emitting component 2, an integrating sphere light source 3, and an integrating sphere leveling base 4. The light source uses a 1000W halogen tungsten lamp 304 as the light source, and the required color temperature of the light source can be adjusted in two ways: one is structural adjustment, adjusting the position of the light source and the light-incident cone 301; the other is adjustment through voltage and current. In the case of limited space, the device is designed with a 500mm diameter sphere, and the inside is coated with a special medium, which can make the light source after diffuse reflection have good uniformity. The light-incident port of the integrating sphere light source is designed with a replaceable aperture, and the light-out port is a stepless adjustable manual aperture. By adjusting the apertures at the light-incident and light-out ports, a wide range of illuminance can be obtained, with an illuminance range of 10lx to 1×10^(-5)lx; and stepless illuminance adjustment is achieved from 10^(-2)lx to 1×10^(-4)lx.

[0031] The specific functional principle of this device is as follows: The integrating sphere light source uses a high-power Class A halogen tungsten lamp (304) as the illumination source. The illumination source is equipped with a complex heat dissipation structure to meet the requirements of long-term operation. The main integrating sphere is a hollow sphere with an inner wall coated with an ideal reflective material. The outer shell of the sphere is made of metal. The illumination source enters the sphere through the light inlet, and after diffuse reflection, it exits from the light outlet, thus obtaining a light source with high uniformity. Its key feature is that the color temperature of the light source is adjustable within a certain range. Simultaneously, the illuminance of the light source is designed with apertures at both the light inlet and light outlet, which can be adjusted accordingly.
