Hu Hong said that the main technical method is an electrical device that changes the luminous flux of the light source in the lighting device and adjusts the illumination level. The purpose of the dimmer is to adjust the brightness of the light. By reducing or increasing the RMS voltage, the average power of the light produces a different intensity of light output.
According to Hu Hong, there are still some problems with some smart lamps: if the communication method adopts ZigBee, an additional bridge is needed, and the connection between the mobile phone and the bridge is unreliable; the Bluetooth node is small, the distance is short, and it is difficult to form a network; The electrical parameters have a narrow range of toning range, no dark blue, dark green, low brightness, and poor color rendering, which does not meet the mandatory safety standards of the lamps. All three methods have their own advantages. The advantage of WIFI is that it is widely used and has spread to thousands of households. The advantage of ZigBee is low power consumption and ad hoc network; the advantage of Bluetooth is that the networking is simple.
Hu Hong said that the current good solution is to turn Zigbee through WIFI, which has the universal compatibility of WIFI and the advantages of Zigbee's low power consumption and low cost.
The application of semiconductor lighting intelligent control market has been widely used in intelligent LED bulbs , intelligent street lamp control systems, smart home entrances, etc. According to Hu Hong, the laboratory has achieved certain research results in intelligent related technologies. Such as the laboratory's WIFI control intelligent lighting technology, the laboratory to solve the problem of light color identity of LED lamps, intelligent home plant cultivation system.
According to Hu Hong, the current laboratory technology conversion companies include Huace Optical Communication Technology Co., Ltd., Huace Optical Communication Technology Co., Ltd., Guobang Xintai Electronic Technology Co., Ltd. The main products include the provision of integrated solutions for visible light communication technology combined with smartphones, Goccia color optical communication technology and intelligent street light control systems.
