LISUN Ulbricht sphere for photometric, colorimetric and electrical measurement of LED lamp

-

A device that is used for photometric, colorimetric, and electrical measurements of LED bulbs is referred to as an Ulbricht sphere. An integrating sphere is another name for an Ulbricht sphere.

Photometric measurements: An Ulbricht sphere is used in the process of measuring the total luminous flux of an LED lamp. This is accomplished by catching the light generated by the LED and dispersing it uniformly throughout the interior surface of the sphere. After that, a photometer is used in order to determine the overall output of light at the entrance of the sphere, which is afterwards transformed into a value of luminous flux (expressed in lumens).

Measurements in colorimetry: The Ulbricht sphere is also suitable for determining the color rendering index (CRI) of an LED light source. A light source's Color Rendering Index (CRI) is a measurement of how well it can reproduce the colors of different objects. Because of the sphere's contribution to the more uniform distribution of the light, it was possible to get more precise readings of the color.

In addition to being used for photometric and colorimetric measurements, the Ulbricht sphere is also capable of measuring the electrical properties of an LED lamp, such as the lamp's forward voltage, forward current, and power consumption. These properties can be measured by using the Ulbricht sphere. These measurements are taken with the LED lamp connected to electrical measuring equipment, and the sphere helps to eliminate any errors that may have been introduced by the angular emission patterns of the LED. These measurements are taken with the LED lamp connected to electrical measuring equipment.

In general, the use of an Ulbricht sphere enables precise and accurate measurements of the luminous flux, color rendering, and electrical properties of an LED light.

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
