[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example

[0021] See Figures 1 to 2 As shown, a capacitive touch remote control for lighting fixtures includes a housing 1, which is a metal housing. A PCB circuit board 2 is disposed within the housing. A touch panel 3 is disposed on the housing, and a capacitive touch functional piece 4 is attached to the inner surface of the touch panel. In this embodiment, the PCB circuit board is a conventional circuit board of the prior art, and therefore is not described in detail, but simply applied. A wireless transmitter is disposed on the PCB circuit board for transmitting signals for remote control.

[0022] Its capacitive touch panel uses a conventional structure found in existing technology. It is a four-layer composite glass screen, with an ITO coating on the inner surface and interlayer of the glass screen. The outermost layer is a thin silica glass protective layer. The ITO coating in the interlayer serves as the working surface, with four electrodes leading out from the four corners. The inner ITO layer acts as a shielding layer to ensure a good working environment. When a finger touches the metal layer, due to the human body's electric field, a coupling capacitor is formed between the user and the touchscreen surface. For high-frequency currents, the capacitor is a direct conductor, so the finger draws a small current from the contact point. This current flows out from the electrodes at the four corners of the touchscreen, and the current flowing through these four electrodes is proportional to the distance from the finger to the four corners. The controller determines the position of the touch point by accurately calculating the ratio of these four currents.

[0023] The touch panel has a touch button area 5 on its back, which cooperates with the capacitive touch function piece, and the capacitive touch function piece is connected to the PCB circuit board. Several limiting pillars 6 and several screw hole pillars 7 are integrally formed on the bottom wall of the housing. A limiting protrusion 8 is provided on the upper part of the inner wall of the housing. During assembly, the PCB circuit board is attached to the top surface of the limiting pillars and screw hole pillars and fixed with screws, and the edges of the touch panel and the capacitive touch function piece are attached to the limiting protrusion 8 and fixed with sealant. This structure improves the effectiveness and stability of the touch buttons. Simultaneously, the limiting pillars and screw hole pillars facilitate the installation and positioning of the PCB circuit board, while the limiting protrusion 8 is mainly used for the installation and positioning of the capacitive touch function piece and the touch panel.

[0024] In this embodiment, a connection interface 9 is provided on the side wall of the housing to mate with the PCB circuit board. This connection interface can be used to connect to a power supply, and the housing contains a power supply battery connected to the PCB circuit board, which can be a coin cell battery or a rechargeable lithium battery.

[0025] In this embodiment, the distance between the limiting protrusion and the top edge of the housing is matched with the thickness of the touch panel. The touch panel is a glass panel, an acrylic panel, or a plastic panel.

[0026] This utility model has positive effects: its structure is reasonably designed, and the combination of a touch panel and a capacitive touch function piece helps to improve the overall appearance and ensures the stability and reliability of touch control. It is also not easily damaged during long-term use, thus extending its service life and making it highly applicable.

[0027] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural parts described in the instruction manual can also be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0028] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all embodiments here. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
