What can a goniophotometer test for outdoor light?

-

The following are some of the outdoor lighting-related factors that may be evaluated with the use of a goniophotometer:

  • Luminous intensity

This parameter, which is often stated in candela, determines the quantity of light that is emitted in a certain direction and quantifies it (cd).

  • Luminous flux

This characteristic determines the overall quantity of light that a source emits, and it is often stated in lumens (lm).

  • Chromaticity coordinates

These characteristics not only define the color of the light that is produced by a source, but they are also used in the calculation of the source's color temperature and color rendering index (CRI).

  • Color temperature

Lower values indicate a warmer (more yellow/red) light, whilst higher numbers indicate a cooler (bluer) light. This parameter is used to characterize the "temperature" of the light that is produced by a source.

  • Color rendering index (CRI)

This metric determines how well a given light source can faithfully reproduce the colors of the things that it illuminates. If the Color Rendering Index (CRI) of the light source is poor, the colors may look washed out or unnatural. A high CRI implies that the light source is able to properly reproduce colors.

  • Illuminance

This value, which is most often denoted in lux, refers to the quantity of light that is incident onto a certain surface (lx).

  • Uniformity

This metric, which evaluates how uniformly the light is dispersed over a surface, is essential for ensuring that there are no shadows or dark areas in the lighting across the surface.

Other characteristics of outdoor lighting, such as the distribution of light and the spatial distribution of luminous intensity, may also be evaluated with the use of a goniophotometer, in addition to these parameters, which are measured by the instrument. For lighting experts who need to analyze and enhance the performance of outdoor lighting systems, goniophotometers are an essential tool because of their capacity to test a broad variety of parameters.

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
