How to test colorimetric parameters of ceiling light with an integrating sphere system?

-

You may use a double integrating sphere to conduct the following tests to determine the colorimetric properties of a ceiling light by following these steps:

  • Prepare the integrating sphere: To prepare the integrating sphere, first ensure that it is spotless, free of any dust or other debris, and positioned in the correct orientation.
  • Install the light source: Install the ceiling light in such a way that it is safe and secure in the middle of the integrating sphere.
  • Measure the light source's luminance: Use a spectrophotometer or colorimeter to measure the brightness of the light source in the integrating sphere. This may be done by measuring the amount of light emitted by the light source.
  • Take down the readings as follows: Make a note of the chromaticity coordinates, color temperature, and associated color temperature as well as the values from the spectrophotometer or colorimeter (CCT).
  • Repeat the measurements: If you choose, you may repeat the measurements using light of varying intensities or color temperatures.
  • Calculate the color rendering index (CRI): Using the values that were previously recorded, you can now calculate the color rendering index (CRI), which is a measurement of the light source's ability to properly portray colors in comparison to a reference light source.

Examine the findings as follows: In order to assess the efficacy of the ceiling light, compare the colorimetric parameters that were computed with the standards that were established by the industry or with the specifications provided by the manufacturer.

The ipx9k High Temperature Pressure Jet Waterproof Test Chamber is characterized by a waterproof grade of 9, indicating high temperature and high pressure water spraying, and spraying high temperature and high pressure water in various directions of the shell for water spraying test. In addition, k represents a function of pressurization, and under such strict conditions, its water pressure will become stronger. The ipx9 is currently a high level of waterproof protection. The IPx9 High Temperature Pressure Jet Waterproof Test Chamber is also widely used in fields such as LED lighting fixtures, display screens, household appliances industry, automobiles, and automotive accessories. At the same time, all dust and waterproof equipment can be customized according to user needs. The ipx9k High Temperature Pressure Jet Waterproof Test Chamber has four different vertical spray angles, namely 0 °, 30 °, 60 °, and 90 °, and the water pressure can reach 8000 to 10000 Kpa; Moreover, its testing r

Capacitance  refers to the ability to hold a charge. It is a medium for realizing the storage and release of static charges, with the characteristic of permanent charge storage. Capacitor components are widely used in power supply filtering, signal filtering, signal coupling, resonance, filtering, compensation, charging and discharging, energy storage, and power separation in circuits. According to its ability to accommodate charges, it is generally measured in Farads, and the international unit is Farads. Therefore, capacitors are essential components for electronics and power. The role of capacitors: Bypass capacitors and decoupling capacitors are two devices that provide energy storage for local devices. Bypass capacitors can reduce load demand, make the output of the voltage regulator smooth, similar to a small rechargeable battery, and can be discharged and charged. The decoupling capacitor can smooth the edge signals of the device, so as to prevent the input signal from being too

1 General 1.1 Scope and object This International Standard(IEC61032) specifies details and dimensions of test probes intended to verify the protection provided by enclosures with regard to: – protection of persons against access to hazardous parts inside the enclosure; – protection of the equipment inside the enclosure against ingress of solid foreign objects. SMT IP10T_AL The object of this International Standard is: – to bring together in one publication object probes and access probes currently specified in other standards, together with any necessary new probes;    – to guide technical committees in the selection of test sphere; – to encourage those concemed to specify test probes in accordance with those already specified in this International Standard rather than modify details and dimensions; – to limit the further proliferation of types of test probe. 1.2 General recommendations When selecting probes, priority should be given to IP code probes. The use of other probes, particul
