A new technology is established by the present invention to assist in the development of more reliable human method for the inspection of pharmaceutical and critical products. The present invention provides the industry with a standardized illumination environment in which the illumination conditions remain constant over extended periods of time. Furthermore, the invention provides the environment in an ergonomic package that is easily adjusted to match physical requirements of individual users without the use of any special tools. The optimized manual inspection environment implements the state of the art control techniques to maintain a constant luminous intensity within an expanded inspection volume. The large inspection volume minimizes the effects of variation in product positions while inspectors perform the operations. The standard environment insures that a constant 550 foot candles is maintained in all manual inspection booths so that inspection results may be compared within the same facility or with facilities located at other sites. A national or international standard for the limiting size of contaminating particles can only be established with the use of standardized manual inspection booth such as presented in this invention.

The invention provides a collaborative dynamic lighting method and a dimmable direct-current incandescent lamp thereof, relates to the field of vision and lighting, and aims to ensure that light is uniform and dynamic in a visual field. The color temperature can strictly imitate candlelight. The core is the direct-current dimming incandescent lamp technology. However, according to existing night desktop lighting, light in the visual field is mostly uneven and static, and the light quality is permanently lower than that of a direct-current incandescent lamp. Therefore, the eyes are easy to adjust and slack, and axial myopia is induced. The direct-current incandescent lamp table lamp is mainly composed of two direct-current incandescent lamp table lamp bodies, one table lamp irradiates books, and the other one irradiates the white wall in front of eyes, the light intensity of the table lamps can be adjusted to guarantee the uniformity of light in the visual field, and optic vertebral cells located in the foveal center of the retina and optic rod cells around the foveal center are stimulated at the same time. Synchronous adjustment of illuminance of the two lamps can be realized according to a program, so that eyes are guided to dynamically focus, and dynamic illumination is realized. The dynamic state is also shown in low-color-temperature lactation lighting imitating candlelightaccording to a biological clock and senile dementia prevention lighting with 40Hz depth stroboflash.
