As a type of reliability test equipment, environmental test has developed into a method to predict how the product use environment affects the performance and function. That is, before the product is put into the market, the environmental test is used to evaluate the degree of environmental impact on the product; When the function of the product is affected, the environmental test is used to find ...
Integrating sphere is a straightforward but frequently misunderstood spectrophotometer accessory for measuring optical radiation. Its job in scatter transmission and diffuse reflectance sample studies is to spatially integrate radiant flux. It is crucial to comprehend how the integrating sphere functions. This is done before one can optimize a spherical design for a certain application. In order t...
A humidity chamber often referred to as a temperature and humidity chamber , is appropriate for testing products like electrical equipment, home appliances, food, trolleys, vulcanized rubber, plastic rubber, metal, and other materials. A range of natural settings in terms of temperature and humidity can be simulated in the chamber. The goal of the entire humidification process is to raise the wat...
Integrating sphere is a kind of sphere that can be used to test: luminous flux, color temperature, light effect and other parameters of light source. Its working principle is that the light is collected by the integrating sphere through the sampling port, and scattered in the integrating sphere after multiple reflections. When using the integrating sphere to measure the luminous flux, the measurem...
What does an Automatic Safety Test System do? Withstand Voltage (AC/DC), Insulation Resistance (IR), Leakage Current (LLC), Ground Resistance (GR), and Power may all be tested using the Automatic Electrical Safety System. Withstand Voltage Test (AC/DC), Insulation Resistance Test (IR), Leakage Current Test (LLC), Grounding Resistance Test (GR), and Power Test were all included in the LS9955/LS9956...
Based on the junction temperature measurement method of high power LED, the ratio of current amplitude to workflow during injection of square wave current pulse into the measured LED device is studied. It is found that the ratio of actual rated current to impulse current is the same. The junction temperature of the LED can be measured by directly measuring the forward junction voltage of the LED u...
What is Ingress Protection testing? An enclosed product’s resistance to liquid and particle infiltration is assessed during ingress protection testing. Depending on the achieved resistance to solid particles and liquids, the product is given an IP rating based on IEC 60529 after testing. The degree of protection an enclosure offers against invasions is tested through ingress protection testi...
How is ESD static electricity generated? Due to external effects such as friction or in the form of various energies such as kinetic energy, potential energy, thermal energy, chemical energy, etc., the positive and negative electricity of atoms will be unbalanced. Friction in daily life is essentially a process of continuous contact and separation. In some cases, static electricity can be generate...
ESD simulator An ESD simulator, often known as an ESD gun, is a portable device that is used to evaluate the resistance of devices to electrostatic discharge (ESD). These simulators are used in laboratories that specialize on electromagnetic compatibility (EMC). ESD pulses are high-voltage pulses produced when two items with opposing electrical charges come into contact. They can be recreated in a...
