Compare LED efficiency and life, the conception of efficiency is more complex. Firstly, there are three kinds of general efficiency, please check the Diagram 1. Luminous Efficiency(lm/W) Conversion Efficiency lamp beads Connect lamp beads to DC power source directly, the rate of lamp beads flux and consumption power Connect lamp beads to DC power source directly, the rate of light powe...
In China, cars are becoming more and more popular. With the development of automobile industry, automotive lights are also developing. Automobile lights have experienced Incandescent Light, Halogen Light and HID(High-Intensity Discharge) Light, to the current era of Automotive LED Light. Automotive LED Light has many advantages: Energy-saving and Environmental Protection: LED directly converts po...
From the perspective of the LED product structure and technology development, the quality criteria of LED product mainly consider the parameters of the optical properties, electrical properties, thermal properties, radiation safety and life. LED optical properties mainly involve luminous flux, radiation flux, luminous efficiency, chromaticity coordinates, correlated color temperature, color render...
“Bright blind” in life is an exaggerated description of some impact incidents, but if it is used for the LED lighting industry, then it is the quality problems of LED lamp itself. And “strobe” is likely the initiator to lead to “blind”. Many people are not very clear about the concept of strobe, and even don’t care about its harm. Regarding the hazard of strobe, experts have given t...
Many customers need aging LED lamps, but do not have a clear concept of aging test and life test. Aging test usually use aging test racks. What is aging test rack? Aging rack is dedicated to simulate the products in real conditions involved in the use of various factors on the aging of the product conditions to strengthen the process of the corresponding conditions. Why we need aging test? Electro...
The International Electrotechnical Commission (IEC) has published IEC 61000-4-5:2014, “Electromagnetic Compatibility (EMC) – Part 4-5: Testing and Measurement Techniques – Surge Immunity Test.” “IEC 61000-4-5:2014 relates to the immunity requirements, test methods and range of recommended test levels for equipment with regard to unidirectional surges caused by over-voltages from switch...
IEC 60825-1: 2007 is a standard issued by the European Union, applicable to safety of laser products emitting laser radiation in the wavelength range 180 nm to 1 mm. Its scope of application would be only applied to LASER products after September 2010, and LED lighting products are no longer covered by the latest version of IEC / EN 60825-1, but need to be assessed in accordance with IEC / EN 6247...
On January 31, 2018, Lighting Poland 2018 arrived on schedule. LISUN has already prepared well for this exhibition. Our booth address is Hall 4 Booth C25 and D26. Our engineers came here two days in advance to prepare the booth. The exhibition lasts three days and ended on the afternoon of February 2. We met old customers and also some new faces during the three days. Our test instruments won the ...
Spectrum is the relative distribution of wavelength and light intensity. The spectrum of LED is generally monochromatic LED, such as blue LED with a peak wavelength of 470nm, with shorter peak wavelength ultraviolet area and with longer peak wavelength green areas as the determination limitation of light intensity. And the spectrum of incandescent lamp, its luminous intensity is widely distributed...
