A detailed view of Goniophotometer and ESD simulator

 The goniophotometer is a device that is used for measuring the emitted light from an object from different angles. The goniophotometer with the LED-light sources was a great hit where the light’s spatial distribution is not homogeneous and the usage of this type of goniophotometer was increasing in recent years. The esd simulator is also called the ESD gun which is used for testing the immunity of devices to ESD which is the acronym of electrostatic discharge. The ESD simulator is specially used in EMC which is the acronym of electromagnetic compatibility where the ESD pulses are high-voltage and fast pulses that are created when the 2 objects of different electrical charges come in contact. 

 


 

The common types of a goniophotometer

The goniophotometer is classified into 3 common types and they are as follows. The first type of goniophotometer is having a fixed horizontal axis and the vertical axis is attached where both are perpendicular to the light source’s main output direction. The second type of goniophotometer has a fixed vertical axis and the horizontal axis is attached where both are perpendicular to the light source’s main output direction. And these both the types are double columns structure.

The third type of goniophotometer is having a fixed vertical axis that is perpendicular to the measurement line and the horizontal axis is parallel to the light source’s main output direction. This type has a single column structures and this type can be used in spot lamp, fixed tube lamp or other devices.

The goniophotometer is used in various applications such as measurement of the light source’s luminous flux and the luminous distribution measurement from the source that is even smaller than the goniophotometer. If the goniophotometer is equipped with color sensors, then it can also measure the additional characteristics like color uniformity and correlated color temperature distribution.

What is the purpose of using goniophotometer?

Image
  The goniophotometer is a photometric device and it can be utilized to calculate the apparent power of the light source at various angles. Mostly, it can be used to verify the luminous fluidity of directed light sources such as automotive and LED headlights. There are numerous series in goniophotometer that covers a massive amount of measuring jobs. More frequently, the smaller devices are used to calculate the radiation information from OLEDs/ LEDs, SSL modules and lamps as well as to measure the light supply of minor faces. While the large goniophotometer can measure the lights up to two metre in diameter and however, very minor LEDs and lights with less light powers.  Different kinds of goniophotometer There are different kinds of goniophotometers available such as: ·        Gravity goniometer/ inclinometer. ·        Universal goniometer that come in dual types include long arm and short arm. ·  ...

How to check the electronic devices emissions with EMC test systems

Image
  Most of the electronic devices have the possibilities of emitting and they may be influenced by the electromagnetic fields. The emc test systems were widely used in various industries as it is one of the important testing processes through which we can know the electromagnetic emissions from electronic devices or equipment. While the usage of electronic devices in daily life were growing and when these devices get in contact can tends to the increase of electromagnetic emissions. In order to avoid such kind of interference it is necessary to know the emissions from the electronic devices. For measuring the emissions from the electronic equipment or devices Electromagnetic Compatibility (EMC) testing is used.    Why is EMC testing required? ·         The electrical products or their installation’s design which undergoes EMC testing were considered to be complete. ·         The EMC testing review...
