LED chip industry crisis approaching
In the past 2019-1911, it was particularly “sad” for the LED industry, especially in the field of LED chips. Overcast medium and low-end capacity and declining prices have been shrouded in the hearts of chip manufacturers. GGII research data show that the overall scale of China’...Read more -
What affects the light extraction efficiency in LED packaging?
LED is known as the fourth generation lighting source or green light source. It has the characteristics of energy saving, environmental protection, long service life and small volume. It is widely used in various fields such as indication, display, decoration, backlight, general lighting and urba...Read more -
Why do LED lights get darker and darker?
It is a very common phenomenon that led lights become darker and darker as they are used. Summarize the reasons that can darken the LED light, which is nothing more than the following three points. 1.Drive damaged LED lamp beads are required to work at low DC voltage (below 20V), but our usual ma...Read more -
What Are “COB” LEDs and Why Do They Matter?
What are Chip-on-Board (“COB”) LEDs? Chip-on-Board or “COB” refers to the mounting of a bare LED chip in direct contact with a substrate (such as silicon carbide or sapphire) to produce LED arrays. COB LEDs have a number of advantages over older LED technologies, such as Surface Mount...Read more -
Lighting products will become more intelligent and more dependent
In recent years, the global LED market has been growing rapidly, which has gradually replaced incandescent lamps, fluorescent lamps and other lighting sources, and the penetration rate has continued to increase rapidly. From the beginning of this year, it is obvious that the market of intelligent...Read more -
Learn About LED Lighting
The Basics of LED Lighting What are LEDs and how do they work? LED stands for light emitting diode. LED lighting products produce light up to 90% more efficiently than incandescent light bulbs. How do they work? An electrical current passes through a microchip, which illuminates the tiny light so...Read more -

With the progress and development of society, energy and environmental issues have increasingly become the focus of the world. Energy conservation and environmental protection have increasingly become the main driving force of social progress. In people’s daily life, the demand for lighting...Read more -
What is the constant power LED driving power supply?
One of the hottest topics in the recent LED power supply industry is led constant power drive. Why must LEDs be driven by constant current? Why can’t constant power drive? Before discussing this topic, we must first understand why LEDs must be driven by constant current? As illustrated by t...Read more -
7 questions to help you understand UVC LED
1. What is UV? First, let’s review the concept of UV. UV, i.e. ultraviolet, i.e. ultraviolet, is an electromagnetic wave with a wavelength between 10 nm and 400 nm. UV in different bands can be divided into UVA, UVB and UVC. UVA: with a long wavelength ranging from 320-400nm, it can penetra...Read more -
Six common sensors for LED intelligent lighting
Photosensitive sensor Photosensitive sensor is an ideal electronic sensor that can control the automatic switching of the circuit due to the change of illuminance at dawn and dark (sunrise and sunset). The photosensitive sensor can automatically control the opening and closing of LED lighting lam...Read more -
LED driver for high power machine vision flash
The machine vision system uses very short strong light flashes to produce high-speed images for various data processing applications. For example, a fast-moving conveyor belt performs fast labeling and defect detection through a machine vision system. Infrared and laser LED flash lamps are common...Read more -
What is a cob light source? The difference between cob light source and LED light source
What is cob light source? Cob light source is a high light efficiency integrated surface light source technology in which led chips are directly pasted on the mirror metal substrate with high reflectance. This technology eliminates the concept of support and has no electroplating, reflow solderin...Read more
