Test method of salt spray test chamber • First power on the salt spray test chamber (plug in) • Press the red power switch, the salt spray test chamber panel from left to right, respectively: the low water level A light is on, the low salt water B light is on, and the low water level C light is on. • Pour distilled water directly into the test chamber, wait until the water level A indicator ...
LM-79 is a standard defining how to test the performance of an LED light or fixture. An LM-79 test is conducted at a time and a single temperature. There is thus no indication of how the performance of the test device (DUT) may vary over time or how various environmental conditions might influence it. The testing techniques typically divide into two ways, integrating sphere and goniophotometer. LM...
The high and low temperature humidity chamber, as its name implies is the experimental equipment that performs high and low temperatures on the product. The production of the high and low temperature chamber is mainly composed of five systems: heating system, refrigeration system, air circulation, control system, and temperature monitoring system. Heating system: The heating system of the high and...
LEDs have opened up new levels of freedom of design which enable architects and designers to free up their creativity. Light-emitting diodes provide many design options in lighting goods. However, a proper measurement technique is necessary to compare important technical parameters to make the most use of the variety of lighting options available. Critical items accessible for the LED testing are ...
In photometry, the light power measurement is performed using two different instruments: a goniophotometer and an integrating sphere. Both have outstanding characteristics that make them suitable for various flux testing and measurement kinds. Although they are employed for the same purpose, ie, for measuring optical power, they have distinct features and principles. While it is clear that the met...
The ESD simulator gun is mainly used to simulate the static electricity on the human body. The main function is to generate a certain amount of static electricity to see whether the electronic products can maintain normal work under the action of static electricity. Then why do we do such a simulation test? Mainly because ESD simulator gun will cause certain harm to electronic components or produc...
An optical goniometer is an instrument that measures an angle or allows an item to rotate to a certain point. The former term applies more in orthopedics. The knowledge and knowledge of measuring the joints in each joint plane are termed goniometry. Thus, a goniophotometer is also derived from this family. The most common usage is the universal standard goniometer, manufactured from either plastic...
Lighting, everything is about lumens. But precisely what are lumens? And how do you comprehend what light bulbs and light fittings contain? And if you want a brilliant and luminous fixture, it is essential to choose the right part for your lighting. In short, the lumen is equal to brightness. Lumens quantify how much light a bulb gives you. More lights indicate that light is brighter; fewer lumens...
Electromagnetic disturbance that degrades the performance of electrical equipment or electronic device, works abnormally or fails. It can be divided into conducted interference test and radiated interference test. EMI Test Standard: EMI test standards for electronic products can be classified according to different types of products: Industrial, scientific, medical: CISPRI1, EN501, GB4824, YYO505-...
