The Goniophotometer is the main measuring device for the light distribution performance test of lamps and lanterns, which can be used to measure the spatial light intensity distribution, total luminous flux and efficiency of lamps and lanterns. The composition of the Goniophotometer system includes: precision turntable and control system, spectral analysis system, standard lamp, alignment system, ...
The test to evaluate and analyze the reliability of electronic products is called reliability test Reliability test is an activity to evaluate the functional reliability of a product in all environments such as expected use, transportation or storage within the specified service life Environmental test chamber The products of the test chambers are widely used in industry, electronics, machinery, a...
UGR refers to the uniform glare value: The International Commission on illumination (CIE) is used to measure the psychological parameters of the subjective response of the light emitted by the lighting device in the indoor visual environment to the discomfort of the human eye. Glare is defined as a visual phenomenon that causes discomfort or reduces the ability to observe details or targets due to...
What Does Salt Spray Testing Mean? An accelerated corrosion test called the salt spray test is used to compare the corrosion resistance of materials that have been exposed to salt spray or salt fog at high temperatures. This corrosion test aims to reveal information about the corrosion resistance of metals and coated metals. Following this test, it is possible to assess whether coatings, paints, a...
What is Climate Chamber? Climate chambers is used to simulate a temperature enviromental condistions, it may also be called environmental chamber or Thermal Chamber or Temperature Chamber. You can click the below videos to learn the details and also how to operate it. Temperature Humidity Chamber | Thermal Chamber | Climate Chamber is according to IEC60068-2-1 (GB/T2423.1) and IEC60068-2-2 (G...
By evaluating the degree of protection given against mechanical incursion, dust, accidental touch, and water into casings and enclosures, ingress protection (IP) testing lowers the risk of product failure in the field. The IP code assigns a classification to enclosures based on how well they protect against solid and/or liquid incursion. The IP Code is made up of the letters IP, two digits, and a ...
An integrating sphere is a spherical object with a reflective coating applied to its inside surface. Numerous tasks, such as measuring light, measuring reflectance, and homogeneous lighting, can be done with reasonable precision using it. This article will discuss in detail LISUN’s integrating sphere, its specifications, what it is used for, and lastly how to calibrate integrated spheres. In...
An electrostatic discharge generator gun, or ESD stimulator gun , is an instrument widely used for ESD testing. Due to its portability and compact size, an ESD simulator can be used in a number of situations. ESD guns are programmable and can detect voltages between 16 kV and 30 kV. This article will explain what ESD stimulator guns are, how they work, and how to use them to perform ESD tests . ...
Goniophotometers are a devices used to test the luminosity of other devices and appliances. This can help ensure the quality of of the devices to be sold and strengthen the position of the seller or the manufacturer of the products in the market. In this case, the photometric measurements taken and the role of the available manufacturers is vital. Goniophotometer A goniophotometer measures the dir...
