• 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….

  • Definition: Means luminaries or light sources emit light intensity distribution in space. It can record the luminous flux of luminaries, light quantity, power, power factor, the size of the luminaries, luminaries efficiency including manufacturer of luminaries, type and other information. But the most critical is to record the light intensity distribution of luminaries in all directions. The classification of intensity distribution curve: light distribution curve according to the symmetry properties usually can be divided into: the axial symmetry,…

  • Standards GB17743-2007 / CISPR 15:2005 <Limits and methods of measurement of radio disturbance characteristics of electrical lighting and similar equipment> instead of the standards GB 17743-1999 and GB 15734-1995. The limits for the 2m loop diameter apply to equipment not exceeding a length of 1.6m, those for the 3m loop diameter for the equipment having a length in between 1.6m and 2.6m and those for the 4m loop diameter for…

  • Due to the demand of Lisun market business expand, and kind invitation from AUTOMATE PROCESS CONTROL, on 9:00am April 23, 2016, Lisun & AUTOMATE organized customer technical seminars in a big hotel at Mumbai, in addition to Lisun’s old and new customers, there are many other technical engineers, who were LED manufacturers, laboratory personnel etc, and on-site customer actively speak, the following is the photos of technical seminar:   Lisun…

  • The lighting industry practitioners must be familiar with IES file. Firstly introduce IES, IES is short for Illuminating Engineering Society of North America. I.E.S is founded in 1906, it is a technical Institute. Institute standardization work is responsible by more than 80 technical committees and subcommittees. Every technical committee is engaged in the research and standard formulation work of various lighting equipment. Investigate various lighting fields and report to director….
