The operation of LISUN integrating sphere system

-

The LISUN integrating sphere system is a photometric and colorimetric testing system that is used to analyze the optical characteristics of LED light sources. This system was developed by LISUN and is named for the company that developed it. Luminous flux, illuminance, chromaticity, color rendering index, color temperature, and spectral power distribution are all examples of these optical qualities.

In addition to this, the LISUN integrating sphere system has the capability of measuring the distribution of spectral power. Before the integrating sphere system can measure the light's optical properties using a spectroradiometer or photometer, the light that is emanating from the LED source must first be gathered and homogenized. Only then will the system be able to work correctly. The inside of the sphere is white and extremely reflective, which allows light to be caught for measurement while also being equally diffused throughout the room.

This is accomplished by the sphere's highly reflective white interior. The system also includes a photometer or spectroradiometer to detect the light and measure its properties, as well as a control unit to operate the system and gather the data it generates. Lastly, the system includes a computer to process the information it generates.

In addition to that, there is a control unit that is a part of the system, and its primary function is to run the system and gather data. Putting the LED source within the sphere of the LISUN integrating sphere, turning on the light, and then collecting data using the spectroradiometer or photometer are the typical steps involved in the functioning of the LISUN system.

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
