How do you use LISUN goniophotometer for LED light measurement?

-

The following procedures need to be carried out in order to measure the amount of light emitted by LEDs using a goniophotometer manufactured by LISUN:

  • Prepare the goniophotometer: Ensure that the goniophotometer is calibrated in accordance with the instructions provided by the manufacturer, and make sure it is installed on a surface that is both stable and level.
  • Place the light source: After positioning the LED light source on the rotating stage of the goniophotometer, adjust the stage's orientation such that the light is pointed in the direction of the detector.
  • Adjust the following parameters for the measurement: Setting the measurement circumstances, such as the measurement range, the detector sensitivity, and the measurement angles, may be accomplished via the use of the software that comes with the goniophotometer.
  • Begin the process of measuring: Utilize the software that comes with the goniophotometer to start the measurement and take precautions to keep the LED light source steady while the measurement is in progress.
  • Examine the information: After the measurement is finished, the software of the goniophotometer will provide the results in the form of a polar diagram. This diagram is a graphical depiction of the angular distribution of light intensity and will be provided after the measurement is finished. In addition to this, the program is able to offer data such as the total luminous flux, the center beam intensity, and several other characteristics that are necessary in order to conduct an analysis of the LED light source.
  • Contrast with standard: Check the results of the measurements against the standards that were defined by the manufacturer or the standards that were significant to the industry, such as IESNA LM-79, CIE121, and so on.

It's vital to keep in mind that the particular procedures may change based on the type of LISUN goniophotometer and the software that's being used, so keep that in mind as you go through the process. In order to get particular information on the correct operation of the apparatus, it is essential to check the manufacturer's instructions and guidelines.

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
