How to use a goniophotometer to test flood light?

-

The following procedures need to be carried out in order to successfully test a flood light using a goniophotometer:

  1. In accordance with the instructions provided by the manufacturer, calibrate the goniophotometer once it has been properly installed.
  2. Place the flood light that has to be evaluated inside of the measuring chamber of the goniophotometer.
  3. Adjust the measuring angles on the goniophotometer so that they correspond to the angles outlined in the standard that you are using for the testing of flood lights (such as ANSI C78.81, IESNA LM-79, LM-80, IEC 13032-1, etc.).
  4. Take readings using the photometer or lux meter that comes with the goniophotometer to determine the amount of light coming in from each angle.
  5. Calculate the photometric characteristics of the flood light by making use of the illuminance values that were measured as well as the calculating procedures that were stated in the standard that you are using.
  6. If necessary, the measurement should be carried out at a number of different locations.
  7. It is essential to confirm that the light measurement meter you are using satisfies the requirements of the standard that you are adhering to and that the circumstances under which you are measuring are consistent with those outlined in the standard. Also, be sure to observe the safety measures, since flood lights may be incredibly bright and may cause harm to one's eyes if they are not used properly.
  8. It is important to keep in mind that the procedure may be different and more complicated depending on the particular standard that you are adhering to. As a result, it is highly recommended that you consult both the standard and the goniophotometer manual in order to obtain more specific instructions.

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
