LISUN LED goniophotometers are designed according to IES standards

-

When it comes to measuring the photometric performance of LED light sources, the Illuminating Engineering Society (IES) has established a set of criteria that LED goniophotometers must adhere to in order to be considered compliant. The Illuminating Engineering Society (IES) publishes criteria that may be used to determine the angular distribution of luminous intensity and the color rendering qualities of LED lighting products.

A device known as a goniophotometer is used for the purpose of determining the luminous intensity of a light source from a variety of vantage points. While doing so, it rotates the light source and measures the quantity of light that is emitted in each of the different directions. This information is used to produce a photometric distribution pattern, which offers a representation of the light output of a source across a broad range of angles. This pattern may be used to make calculations about how much light is emitted from different directions.

In order to take out photometric measurements and report one's results, one must first familiarize oneself with the methodology and procedures that are outlined in the IES standards. These consist of suggestions for apparatus, sample preparation, measuring conditions, and the interpretation of results. By adhering to these standards, manufacturers of LED goniophotometers may assure that their devices give reliable and consistent readings, which permits fair comparisons and evaluations of different LED lighting solutions.

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
