After 2 weeks of intensive market research on the different types of photo-therapy products currently in the market, it is finally time for us to present our findings to the company supporting us in this project – 杭州浙大三色仪器有限公司Zhejiang University SENSING Instruments CO LTD.
SENSING Instruments is founded by professors from Zhejiang University, specializing in research and development of LEDs lightings. It is currently one of the most advanced in LEDs technology in the country, meeting many international standards.
We were first given a tour of the R&D laboratory of the company and we come across many of the professional equipment used in the lighting design industry.
This is a Spectroradiometer that are used to measure the spectral power distribution of the lighting source. It measures the spectral irradiance and spectral radiance and through complex mathematical calculation by the software, it is able to tell us the source color, chromaticity, spectral power, illuminance and luminance.
This is a Goniophotometer used to measure light distribution and luminous flux of lamps and luminaires for general lighting applications. It is an important test because LED light source are mostly directed light sources where the spatial distribution of light is not homogeneous. The data obtained from the test can then be entered into software like DIALux, where lighting designer will be able to model how a room will look like under different lighting conditions.
