Five kinds of LED Efficiency

Compare LED efficiency and life, the conception of efficiency is more complex. Firstly, there are three kinds of general efficiency。 Firstly, for lamp beads, there are two concepts of efficiency: Lamp beads luminous efficiency, how much light can be issued every 1W input power. This efficiency is the indicator to measure the light efficiency of […]

LISUN Engineer goes to India customer to carry out LPCE-3 installation training.

LISUN Engineer goes to India customer to carry out LPCE-3 installation training.

Recently, LISUN engineers outside India, to do the installation training of LPCE-3 compact spectrum radiometer integrating sphere system for customers. The customer ordered the LPCE-3 compact spectrum radiometer integrating sphere system from LISUN this time. LPCE-3 is a CCD Spectroradiometer Integrating Sphere Compact System for LED Testing. It is suitable for photometric and colorimetric measurement […]

Installation & Training in Bhutan

Recently,LISUN engineers went to Bhutan customer company for installation training.Customers bought the LPCE-2 high precision radiometer integrating sphere system and LSG-1200A compact distributed photometer from LISUN. LPCE-2 is an Integrating Sphere Spectroradiometer LED Testing System for identifying the performance of single LEDs and LED lamps. LED’s quality should be tested by checking its photometric, colorimetric […]

How to predict the life of LED?

In general, LED can be used for more than 50000 hours, and some manufacturers are promoting their LED to operate for about 100000 hours. The main problem in this area is that LED is not simply no longer operational. Its rated service life can not be calculated by traditional lamps and lanterns. In fact, when […]

Two Directions on LED Intelligentized: Intelligent Agriculture and Lifi

With 4.0 concepts emerged on the industry, the traditional mind of manufacturing is experiencing unprecedented impact, integration and upgrade of industrialization and information will be the main theme of the transformation for production structure in the future. LED industry as a huge lighting market, in the new historical situation, only LED intelligent road can go […]

If you test high power small size HID lamp, how do you choose Integrating Sphere?

HID lamp refers to the general term for High Intensity Discharge lamp. High pressure sodium lamp, high pressure mercury lamp, xenon lamp, metal halide lamp belong to HID lamp. We generally use Integrating Sphere Spectroradiometer Test System to test the photometric, colorimetric and electrometric parameters. Generally we suggest the diameter size of Integrating Sphere according to the […]

The Methods and Principles of Applying Interference for LED Lighting Burst Test

When doing EFT test, there have L1, L2, L3, N and PE interface. PE and earth are two different concepts. Electrical fast pulse interference is common mode, in the experimental setup figure of the standard, we can see the signal cable which is from the test generator can connect with corresponding power lines (L1, L2, […]
