This series features transparent LED screens, which are suitable for various indoor places and various stores, especially in storefronts with floor-to-ceiling glass windows. Installing the transparent screen against the glass wall has a very good effect. When the display is turned off, the audience can watch the indoor environment from the outdoors, and when the display is turned on, they can directly watch the content played on the display.It not only preserves the visibility in the store, but also can effectively display advertising videos to the other party, which is very practical.

Most of the solutions for changing the color temperature of LED bulbs currently on the market are realized by expensive wireless remote control methods (Zigbee, WIFI, Rf). However, this high-cost LED bulb that can change the color temperature is naturally high in price, and it is difficult to enter the home of the people. Moreover, the hand-held remote Controller is easily lost.
In order to solve the above problems, this solution will introduce the ON_OFF switch on the wall of the home to change the color temperature of the LED bulb. The scheme consists of two parts: (1) AC/DC constant current source, and (2) intelligent color temperature. Select the switch module (with switch status memory function). Its working principle and schematic diagram are shown in Figure 1. 
The application scheme will be further described below in conjunction with a specific example. Simple sample of the scheme is shown in Figure 2, Figure 3 and Figure 4: 
1. Input voltage 85-265VAC
2. Intelligent color temperature selection switch module function
2. 1 Module power-on initialization Select output 4000K color temperature.
2.2 If there is no ON_OFF action within 5 sec of power on, the intelligent color temperature selection module will automatically remember the current color temperature selection state. After the bulb is powered up next time, the intelligent color temperature selection module will re-export the last color temperature selection state, and the drive line adjusts the correlated color temperature.
2. 3 If the user needs to change the color temperature (the power-on time exceeds 5SEC) in the currently selected color temperature state, just press the wall switch in the current power-on state:
OFF---ON---OFF---ON---OFF---The next ON will enter the color temperature conversion state; as long as you enter this state (each time does not exceed 5SEC), each subsequent The secondary ON will cycle through the 6000K3000K4000K color temperature. If it is determined that a certain color temperature is selected, the ON time exceeds 5SEC, and the module will automatically save this state.
