Can LISUN integrating sphere test big LED flood lights?

-

Large LED flood lights are no match for the LISUN integrating sphere's ability to do comprehensive quality assurance testing on them. In order to determine the total luminous flux that the LED flood light produces, the integrating sphere must first collect all of the light that it generates and then determine its mean value (lumen output). It is common practice to coat the inside surface of the spherical with a material that is highly reflecting.

This coating serves to prevent measurement errors that are produced by variances in the direction in which the light is emitted, therefore it not only adds to the even distribution of light inside the sphere, but it also helps to make the sphere more opaque. After the light has been amassed, it is directed in the direction of a photometer or spectrometer, which analyzes the light by determining its intensity as well as the dispersion of its wavelengths.

Because of this, it is possible to calculate a variety of various optical characteristics, such as the luminous flux, the color temperature, and the color rendering index. The size of the LED flood light that is being evaluated is what defines the size of the integrating sphere that is required for the evaluation; larger spheres are required for LED flood lights with a wider coverage area. LISUN offers integrating spheres that are available in a number of different sizes, which enables them to be used with a comprehensive selection of LED lighting fixtures.

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
