I. Overview:
This system is a high-performance LED remote dimming controller, which is mainly used for all kinds of LED lights (5-20W) that need to adjust the color temperature, such as LED bulb lights, LED ceiling lights, LED downlights, etc. Using 2.4G high frequency wireless remote control and touch switch panel control, it has the characteristics of low power consumption, long transmission distance, strong anti-interference ability, and high air communication rate. The remote control has a stylish and beautiful appearance, practical and simple functions. With dimming, color temperature, free grouping and synchronization control. The modular design of the controller, the connection point and the fixed point are combined together, which is convenient for compatibility and secondary development with the aluminum base plate of the lamp.
2. Features:
(1) The new solution --- It still supports remote control. The difference is that we advocate one-to-one control (one remote control controls one light or a group of lights), and the group control multi-group control is removed. The remote control is our own Private model, beautiful and generous, silk screen image clear, color temperature remote control silk printing (snowflake, small sun, small moon), RGB/RGBW/RGBCW remote control, (snowflake, small sun, small moon, color silk screen, colorful static, dynamic cycle Gradient), all have memory function keys. Considering the cost and practical sensitivity, we adopt the button type. Suitable for all people, simple, practical and easy to operate; and we have added a strong magnetic adsorption function, install the base on the wall, can be taken and released freely according to needs, and is not easy to lose.
(2) New solution-Considering the complexity and imperfection of the mobile APP, we do not recommend it, but in order to increase the product highlights of the solution, we have worked hard on the switch control panel, not only retaining the ordinary switches The characteristics of opening and closing of the base are also innovated based on the touch switch panel on the market, so we have a 2.4G smart touch switch panel that combines the advantages of seven major functions:
★Perceived-integrated sensor, can perceive the surrounding environment, automatically adjust the brightness and color temperature
★Backlight-Passive and zero power consumption backlight, visible at night without glare
★Capacitive touch-high-sensitivity capacitive touch design
★Working mode---switch between smart mode and manual mode at will
★Removable-strong magnet adsorption
★Wiring-free-battery powered, wireless control
★Free installation-can be pasted, can be screwed on the wall
Third, the connection between the power supply and the module:
Precautions for power supply design (special attention is required)
This system needs a constant current or constant voltage power supply, and has a fast response speed. The pwm of the control module is almost 4M (1000*4000) frequency, which is not possible for a constant current source that uses source-side detection current. (Reason That is, the response speed is too slow, which will cause LED lights to flicker, jitter, poor modulation and other problems. Maybe some power supply manufacturers can do this, and customers need to test the type by themselves), using a secondary transistor to detect the feedback power supply, and the response speed is fast. (There is also the direct use of the threshold voltage of the optocoupler to achieve constant current. The effect is also very good, but the efficiency is slightly lower. It is the same as the principle of using a transistor to detect constant current, but the threshold voltage of the transistor is lower, and the efficiency is higher. ). Generally, there is only one negative pole of the power supply. The led- and V- can be connected on the control board, but the effect will be worse at low brightness. The negative pole of the power supply can be divided into two, LED- is the ground that has been tested by constant current, and V- is the final ground. In this way, the electricity used by the control module will not be tested by constant current, and the effect will be better at low brightness.
to sum up:
This is just a simple introduction. The physical product will make you feel more practical. But many people say that there is no need to pay attention to the lights at home. I installed an ordinary switch, which should be 80% of the current domestic The opinions or opinions of the above people are precisely because of this point of view. The 2.4G dimming control LED lights are basically aimed at the foreign market, so the domestic is still in the traditional lighting control method, and the historical car wheel is constantly rolling. Before, the times are different. We humans should also keep pace with the times and cannot be at the forefront of the intelligent age of the Internet of Things, but at least we must work hard to get closer. The home is a place to make and feel and share love, and the light is to add light to the home. Color, in today's environment where the pressure of the big environment is huge, we even expect our home to be a warm, comfortable and romantic place. Imagine that the lamps in the home can automatically adjust the color and brightness of the matching lamps according to the changes in the surrounding environment. You don’t need to hold it anymore. The mobile phone or remote control can be used to adjust, the mobile phone can be used to do more and more meaningful things. (Follow current affairs information, chat, answer phone calls, shopping, watching movies, etc.) Is this way to experience the high-end, high-end smart life experience more comfortably?
