IEC/EN62471 is the European Union’s testing standards for laser products (including LED). IEC/EN 62471 is designed to evaluate the optical radiation hazards associated with different lamps and lamp systems. And it is also used to replace the IEC/EN60825 standards in the requirements of the LED product energy level. It increased the requirements of the optical biology, including radiation intensi...
Electrical Ballast is one kind of the ballasts; it is the electronic equipment which adopts electronic technology to drive the electrical light source to produce light. Modern Fluorescent lamps increase to use electronic ballast, compact and small, even can integrate electrical ballast and lamp tube, at the same time, electrical ballast usually can be compatible with starter function, thus it can ...

UV aging test chamber is suitable for the aging test of non-metallic materials resistant to sunlight and artificial light. Light source adopts eight UV fluorescent lamps that rated power is 400W as a light source. UV fluorescent tubes are distributed on sides of chamber, every side has four (There are UVA-340 and UVB-313 light source for users to select the configuration). UV aging test chamber is...
The CV model load is the basic of the LED power supply test. CV is constant voltage, but the load is only the current load equipment, itself does not provide constant voltage, therefore, the so-called CV is just through the voltage negative feedback circuit, to servo the change of LED power supply output current, to make the LED output capacitor charge balance, thus achieve the purpose of constant...
Glow wire test is to test the stability of electrical and electronic products during working. And the hot wire itself is the resistance wire ring with fixed size. When doing test, the wire ring should be heated up to the specified temperature by electricity, so that the time when the top of the wire reached the sample can meet the time standard required, then observe and measure its state. The tes...
IEC 60529 (GB4208-2008) IP code is a coding system to indicate the degrees of protection provided by an enclosure against access to hazardous parts, ingress of solid foreign objects, ingress of water and to give additional information in connection with such protection IP code includes 4 digits, like IP23CH. IP short for ingress protection; numeral 2 stands for first characteristics and can be ins...
Power supply is the device to change other forms of energy in to electric energy. Power supply products are widely applied in industry automation control, military equipment, scientific equipment, industrial equipment, computers, communications equipment, electrical equipment, instruments, medical equipment, semiconductor refrigeration and heat and other fields. There are two common types of major...
