This solution is widely used in current smart LED bulb products. In this year's Hong Kong Autumn Lighting Exhibition, customers have adopted this program extensively. This program is mainly divided into five parts: AC-DC constant voltage module, DC-DC constant current module, output buck module, Bluetooth control module and LED color change module. 1 Intelligent LED Bulb Light Bluetooth Solution Principle As shown in Figure 1, the intelligent LED bulb light Bluetooth solution can be divided into four modules: AC-DC constant voltage module, DC-DC constant current module (the number of which is determined by the color effect), LED color change module and Bluetooth Control module. The following is a detailed description of the functions of each module: Principle frame figure 1 1.1 AC-DC constant voltage module If the AC-DC constant voltage module is combined with the DC-DC constant current module, then it is a multi-channel constant current output LED switching power supply, and the AC-DC constant voltage module is a constant voltage output switch. power supply. Because it involves the need to control the different states of the multi-output to achieve the purpose of color temperature adjustment, the integrated AC-DC constant current switching power supply scheme is not directly used here, if the AC-DC multi-output chip is directly used for design. It will encounter similar problems such as mutual interference between each output, and each channel's dimming signal will interfere with each other. Therefore, it is still a mode that uses AC-DC constant voltage and DC-DC to achieve constant current. This module mainly realizes the function of converting AC mains into DC constant voltage level to power the rear DC-DC module and Bluetooth control module. Fiber Fast Connector features a pre-polished ferrule that couples to the fiber being terminated by precision mechanical alignment, insuring low loss with a proprietary gel. The main types for Fiber Optic Fast Connector are SC Fast Connector , LC Fast Connector , FC Fast Connector ,Fiber Splice On Connector. It is also called ftth fast connector, which is already a popular solution for optical wiring inside buildings and floors for LAN & CCTV applications and with the expansion of FTTH. Meanwhile Fiber Optic Quick Connector is already proving itself to be the connector of choice by incumbents, municipalities, utilities & alternative carriers. Installation of Fiber Quick Connector requires some fiber preparation tools,such as a fiber stripping tool, wipes and a fiber cleaver. No electrical power supply is needed for Fast Connector Fiber Optic. Foclink,a reliable supplier of fiber fast connector,is always beside u 7*24.
