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 automoti...
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 envi...
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 lightsource, 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 i...
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 w...
Combination wave generator is a high reliability analog lightning surge wave 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 ea...
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 sourc...
Lisun LMS-6000 Portable color spectroradiometer is the only one used telephoto optical system in portable spectrometer spectral radiometer, spectral resolution is 0.2nm, which can measure LED wide spectral light source and also can measure CFL, HID narrow spectral light source. It can be calibrated automatically by itself. Do not worry that the dark background changed affects the measurement resu...
IES TM-30-15 is a document approved by the Illuminating Engineering Society (IES) that describes a method for evaluating light source color rendition. The method encompasses several individual measures and graphics that complement one another and provide a comprehensive characterization of how the light will affect the color appearance of objects. The three highest-level components of the system a...
LED luminaries consist of LED power driver, single LEDs and fixtures, which the LED power driver is like the heart of human, so it is the key part. Since the LED is sensitive semiconductor device and also has the negative temperature characteristics, it needs to be applied in steady state operation and protection in the application, resulting in a drive concept. LED devices is strict with LED powe...
