• In today’s life, LED is applied for widely usages in order to save energy. And as we know that it needs a power driver which will directly affect the life of the LED. Therefore, how to make well a LED power driver becomes the most important for LED power supply designers. 1. The power driver will directly affect the life of LED LED power driver includes digital driving and analog…

  • With the fast development of electrical industry in China, manufacturing enterprises scale grows constantly, international electric safety standards apply more and more widely. Lighting industry standards are also widely used. International standard IEC60598 general requirements and test cover classification of luminaries according to degree of protection against ingress of dust, solid objects and moisture, marking, mechanical construction and electrical construction. International Standard IEC 60598 specifies general requirements for luminaries for…

  • India lighting market develops rapidly, research reports point that LED lighting market scale will reach 1.14 billion dollars, growth 47.1%. India government intends to make India to be the lighting products export hub for East Asia and Gulf States, many international large factories have India as the production base for the global market, so India LED lighting market domestic and external demand is large, the market will grow rapidly in…

  • Different color temperature will give us a different feeling. In a different environment with the same brightness, the object’s color we can see will be a great difference. It is not difficult for us to find that there are different colors when we go to different places. There are also different color temperatures in different environment, which will also bring us a different mood. In commercial establishments, we shall provide…

  • Nowadays, there are two main categories of LED light sources classified according the forms on the market, one is COB integrated light source directly combined of multiple chips, the other one is SMD made by a single LED light source pasted on the PCB. Characteristics of light source: There are both advantages and disadvantages between the two kinds of light sources. For COB integrated light source, the light-emitting surface is…

  • Combination wave generator is a high reliability analog lightning surge generator designed for lightning production enterprises. It is suitable for Electromagnetic compatibility (EMC) – Surge immunity test. It can test impact current absorption capacity and impact current anti-jamming capability for related electronic components, overvoltage protector, electrical circuit etc. To assess each port of EUT is subjected to transient overvoltage disturbance immunity, it provides an accurate and ideal basis. It has…

  • LED is short for light emitting diode. It is one kind of semiconductor diodes, which can convert electrical energy into energy. With the technology development, LED lighting applications are more and more. How is the development trend in future? For lamps, it mainly has intelligent lighting, agricultural and horticultural lighting, wireless control device and people-oriented lamps. Lamps combine with Internet of things, which makes some special application possible. Base on…

  • Nowadays, with the development of LED industry, its technology continues to be mature and has widely applied at home and abroad. Comparing to mature markets in Europe and America, LED lighting industry also has been very popular in Southeast AsiaBlueOcean market. Currently, it has not been strictly required for indoor LED lighting product specifications and certification in the Southeast Asian market. The demand for most LED lighting products is still…

  • LED has the features of long life, but with the different working condition and drive current, its life will be different, but generally the life will be around 50K hours. Differ from the traditional light source, LED light will decay gradually rather than extinguish instantly. According to the standard IES-LM-80, IES-LM-82 and TM-21, the requirements of the test cycle is generally 6000hr, and it introduced the conception of L70, L50…

  • It is quite important for factories and users to prevent equipment from electrostatic discharge. With the wide application of microelectronic components, to improve the reliability of products and systems, we urgently need to identify various factors of problems to find a solution. The accumulation of static electricity and discharge problems become a greater concern because of uncontrollable environmental conditions and equipment and systems wide application in factories and mines. Whenever…

  • We know that LED lamps have many models. Here we introduce the main models. It is classified as bayonet, screw and so on from installation methods. It is classified as bakelite, plastic, metal and ceramics from materials. Usually lamp holders such as E27 are the most common energy-saving lamp screw lamp holders, while fluorescent lamp holders are usually called T8 lamp holder or T5 lamp holder etc. Usually we use…

  • LED automotive light adopts LED (light emitting diode) as a light source. Since the LED possesses advantages of high brightness, variety of colors, low power consumption and long life, and it has enhanced that daytime running lights must be applied for motor vehicle in European before 2011, LED is more widely used in automotive interior and exterior, especially the application of interior automotive color LED lighting has been very mature….
