Six indexes for judging the performance of LED light source and their relationships
To judge whether an LED light source is what we need, we usually use an integrating sphere to test, and then analyze the test data. The general integrating sphere can give the following six important parameters: luminous flux, luminous efficiency, voltage, color coordinate, color temperature, and...Read more -

Railway, port, airport, expressway, national defense, and other supporting sectors have risen quickly in recent years against the backdrop of domestic infrastructure and urbanization, providing growth opportunities for the development of the industrial lighting business. A new era of industrial t...Read more -
Analysis of main technical routes of white LED for lighting
1. Blue LED chip+yellow green phosphor, including polychrome phosphor derivative The yellow green phosphor layer absorbs the blue light of some LED chips to produce photoluminescence, and the blue light from the LED chips transmits out of the phosphor layer and converges with the yellow green lig...Read more -
Nine secrets of high quality LED bulb driving power
The development of LED lighting has entered a new stage. The high-quality LED bulb driving power supply for modern lighting has the following requirements: (1) High efficiency and less heat Because the power supply is usually built-in, together with the LED bulb beads, the heat generated b...Read more -
Why are led lamps easy to break in summer?
I don’t know if you have found that whether it is led bulbs, led ceiling lights, led table lights, LED projection lights, led industrial and mining lights, etc., it is easier to break down in summer, and the probability of breaking down is much higher than that in winter. Why? The answer is...Read more -
Ten hot spots of LED application technology development
First, the total energy efficiency of LED light sources and lamps. Total energy efficiency = internal quantum efficiency × Chip light extraction efficiency × Package light output efficiency × Excitation efficiency of phosphor × Power efficiency × Lamp efficiency. At present, this value is less th...Read more -

Comparison between LED human body induction lamp and traditional human body induction lamp
Infrared human body induction lamp uses the thermal infrared emitted by the human body to detect and generate electrical signals by thermal induction elements. Through the induction device, the lamp can be controlled to turn on and off. It has the characteristics of light on when people come and ...Read more -
Heat dissipation design extends the service life of LED. How to choose and use heat dissipation materials?
Developers can improve the efficiency and service life of led through effective heat dissipation management. Careful selection of heat dissipation materials and application methods is very important. We need to consider an important factor in product selection – the application of heat diss...Read more -
Parallel design in LED drive design
Because of the VF value characteristics of LEDs, some VF values will change with the temperature and current, which is generally not suitable for parallel design. However, in some cases, we have to solve the problem of driving cost of multiple LEDs in parallel. These designs can be used for refer...Read more
