The devices of electricity and electronic equipment which are attached to power and signal line are prone to the transient overvoltage occurrence as a result of lightning strike, switching in the grid, and inductive load interrupt. In order to test immunity to these disturbances, a 10kV surge generator that can reproduce controlled high-energy pulses is used to test immunity in laboratories. In pr...
Modern lighting design, compliance and performance validation require accurate assessment of luminous intensity distribution. The goniophotometer operation is the basis of this assessment as they allow the angular analysis with great precision of the light produced on luminaire. This is the core step in professional laboratories in light measurement, particularly in measuring fixtures that are pla...
The correct light output measurement is essential to determine the actual output of the current lighting products. An Integrating sphere is a dedicated device specialized to quantify total luminous flux in a controlled and repeatable fashion, and therefore used as a required apparatus in checking both initial output and long-term stability. The lumen sphere in illumination is important in professi...
Innovative products are supposed to perform in various weather conditions under extreme temperatures and humidity, high or low rates of climatic changes, as well as being exposed to stress in the course of many years. The issue is eradicated by means of an environmental test chamber through which the controlled laboratory solution will reproduce these conditions with repeatability and accuracy. At...
Proper measurement of undesired emissions is an essential need in the contemporary electronics. In compliance testing, the engineers are required to maintain emission within the limits required by legislations under standardized measuring conditions. An important constituent of this process is the electromagnetic test of interference, wherein the way of detection is indicated and evaluated in rega...
Effective assessment of corrosion is not only based on the length of exposure but the level of control of the test environment. A salt spray test is based on specifically controlled parameters to create the imitation of the aggressive corrosive environment, and even minor changes can distort an outcome. In an experimental corrosion test environment, calibration is used to assure that the temperatu...
Electronic equipment installed into real-world conditions is often vulnerable to transient overvoltage conditions due to lightning strikes, switching of power grids, interrupting inductive loads, and electrostatically couple with impractical ground. To ensure that the products will not fail and get away during such events, engineers use a surge wave generator that recreates standardized high-energ...
It is equally crucial to know the way light is scattered in space as it is that the luminaire produces a specific amount of light. In case of LED luminaires, optical behavior defines visual comfort, energy savings and lighting standard. The major instrument of measurement of this spatial light behavior is a goniophotometer. In the process of testing the professional IES, goniophotometer records fi...
Since the development of LED technology, recent lighting fixtures are generating a high level of luminous intensity, which in most cases are tens or even hundreds of thousands of lumens. Such strong sources of light need special photometric systems to measure accurately. Specifically, a large integrating sphere has been developed to deal with these high-lumen conditions with a stable and accurate ...
