Description

Technical Field

[0001] This utility model relates to the field of dimming controller technology, and in particular to a multi-channel dimming controller with touch function. Background Technology

[0002] In conventional use, touch panels typically employ tempered glass, PC material, or non-conductive materials, offering a relatively large touchable area (over 50mm wide). The advantage is that the electrical charge on the human body can be transferred through the panel to the PCB sensor, thus enabling operation. Modern appliances (such as kettles, air conditioner panels, and induction cookers) mostly use single-button touch controls. Furthermore, assuming no metal interference around the touch panel, actions are generally limited to single clicks and long presses, resulting in limited functionality. Adding or removing functions requires long presses or multiple touches, leading to a poor user experience. Especially when the structure is enclosed in metal, touch functionality is prone to issues such as false triggers, delays, and low resolution.

[0003] In terms of LED dimming methods, rotary knobs, buttons, and separate touch controls (SCR touch controllers, DALI touch controllers) are commonly used. SCR or DALI touch controllers can only dim a single channel. If a system requires multiple light brightness changes or is used in an RGBW color dimming series, multiple controllers are needed to control all channels of light. Utility Model Content

Based on the existing aluminum panel structure, by setting a touch MCU chip circuit and a multi-channel MCU circuit and other PCB touch-dedicated circuits, it solves problems such as false triggering and response delay. It can realize multi-point touch control with arbitrary displacement and sliding dragging effect in a limited area, increasing the user experience and sense of layering; and solves the bottleneck problem of one-to-one dimming.

The socket port circuit is electrically connected to both the touch MCU chip circuit and the multi-channel MCU circuit. Understandably, in practical applications, the aluminum profile (conductor) used in the touch PCB sensor sheet serves as a decorative panel, with a touchable area only 14mm wide. Charge on the human body will quickly flow away through the aluminum profile. Its triangular shape with pointed ends theoretically better guides charge accumulation, enabling multi-touch and sliding / dragging effects.

The microcontroller chip U1, capacitor C69, resistors R49, R91, and R92 are all connected to the storage IC chip U11. The storage IC chip U11 uses a 24CXX chip, which is a power-erasable programmable read-only memory (PER), meaning data is not lost after power failure.

[0022] Understandably, this utility model features a reasonable design and unique structure. Based on the existing aluminum panel structure, it solves problems such as false triggering and response delay through a self-programmed algorithm and a dedicated PCB touch circuit. It enables multi-point touch control with arbitrary displacement and sliding / dragging effects within a limited area (50mm x 14mm), enhancing user experience and depth; it also solves the bottleneck problem of one-to-one dimming. This utility model uses a programmable MCU (ST series) with touch functionality, allowing for secondary development and expansion of the chip's built-in touch function. Due to its built-in dedicated touch control (multi-point touch), it ensures consistency and reliability in mass production, enhancing anti-interference capabilities and providing multi-point, non-positional touch control, sliding / dragging, and instant response effects.
