Recently, the new museum of the Guangdong Provincial Museum is open to the audience free of charge. In order to better display the precious cultural relics and provide a good visual environment for the audience, the new museum of Guangdong Province uses a large number of LED lighting technology. I

I. Introduction This article refers to the address: http:// Modern Data Visualization technology refers to the theory, method and technology of using computer graphics and image processing technology to convert data into graphics or images on the screen and interactive processing. It involves c

The Principle and Realization of Medium Wave Q Table Principle: Ultra low impedance signal voltage source is output across R4, which is connected in series in the LC resonant circuit. When the circuit resonates, the inductive and capacitive reactances of L and C cancel each o

Abstract: The circuit drives a high-power white LED (WLED). When the temperature is too high and the thermistor has an open or short circuit fault, the LED will be turned off. Summary of white LED driver with high temperature protection function: The circuit drives a high-powe

What is semi-indirect lighting? (semi-indirect lighting) semi-indirect lighting The 10%-40% portion of the luminous flux emitted by the luminaire is projected directly onto the illumination on the hypothetical working surface. What is general diffuse lighting? (general diffused l

One of the main challenges in communication system design is how to successfully capture high-fidelity signals. To avoid strong interference effects, signal distortion, and reduced sensitivity, cellular communication systems must meet the stringent requirements of cellular st

Tohoku University and ROHM have increased the luminescence intensity of ZnO (zinc oxide)-based UV LEDs to 100 μW, which is 10,000 times that of the original products. This luminous intensity is about 1/10 of that of InGaN and GaN-based UV LEDs, "clearing the way forward to

Sanan Optoelectronics (600703, stock bar) (600703, closing price of 37.33 yuan) announced on the 19th, according to the "Sanan Optoelectronics Wuhu Optoelectronic Industrialization Project Investment Cooperation Agreement" signed with the People's Government of Wuhu City, Anhui Provin

Now LED investment is indeed overheated, and LED industry shuffling is inevitable. In July 2010, Hangzhou Bay LED Industrial Park, the largest LED industrial park in Zhejiang Province, will be put into production. The Hangzhou Bay LED Industrial Park, located in Haiyan, Zhejiang, covers an area of

The people who come to Ningnan Xiji and the residents who live here will find that the street lights of Xiushan Road in the county are not the same as the street lights in other places. It turned out that it is a wind-solar complementary street lighting project, that is, the energy-saving "low

The application of amber LED mostly lies in wall washers, headlights, traffic lights, etc. For the high brightness requirements and high operating temperature requirements of the above applications, the amber LEDs on the market are not suitable for use; traditional amber LEDs use AllnGap quaternary

Covering the entire industrial chain, Yangzhou will become the largest LED industry center in China Yesterday, the employees of Yangzhou Chaoyang Company were braving the hot sun, fighting in the production line, and installing signal lights for the Dalian city light rail. The lighting installatio
