CIE 84 colorimetric measurement with LISUN integrating sphere

-

The CIE 84 colorimetric measurement using an integrating sphere is a technique that is used in the process of determining the color characteristics of a light source. In line with the CIE 84 standard for the color rendering index (CRI), this measuring technique is used to determine the color rendering qualities of lighting systems such as LED lights and other types of lighting. The color rendering index, or CRI, is a numerical measurement that ranges from 0 to 100 and indicates how well a light source can reproduce the colors of objects in comparison to a standard light source.

During a CIE 84 colorimetric measurement using an integrating sphere, light from the LED light source is directed into the sphere, and the light from the LED light source is then diffused uniformly around the inside surface of the sphere. A spectroradiometer is used to make precise measurements of the homogeneous light field that is produced by the inside surface of the sphere, which functions as a diffuse reflector. The spectrum of light that is produced by the LED source is measured by the spectroradiometer, and this information is then used for the calculation of the LED's color characteristics, such as the CRI value.

Lighting designers and engineers may guarantee that the LED light sources they employ in their applications produce correct color rendering by completing a CIE 84 colorimetric measurement using an integrating sphere. This gives them the ability to build aesthetically pleasing settings.

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
