Description

Technical Field

[0001] The utility model relates to the field of optoelectronics, in particular to a luminous potentiometer. Background Art

[0002] The luminous potentiometer is an innovative electronic component that combines a potentiometer and a SMD LED light. It originates from the demand for the integration of potentiometer functions and lighting effects. With the advancement of technology and people's continuous pursuit of product appearance and functions, the traditional potentiometer design has gradually become simple and ordinary. The widespread application of LED technology has brought new possibilities for electronic components. And with people's continuous pursuit of product experience and beauty, the luminous potentiometer is expected to be widely used in various electronic devices, bringing users a more convenient, beautiful and practical experience.

[0003] The main structure of a traditional light-emitting potentiometer usually includes an LED lamp, a fixed end, a sliding contact and a variable end. The fixed end is connected to a fixed position in the circuit, while the sliding contact can move along the surface of the potentiometer to change the resistance value of the potentiometer. The variable end is connected to a variable position in the circuit, and the resistance in the circuit is adjusted by adjusting the position of the sliding contact. LED lamps are usually composed of LED chips, packaging materials and connecting wires.

[0004] However, traditional luminous potentiometers usually require additional space to install LED lights and related circuits, so the overall volume is relatively large, and can only provide a single color lighting effect, lacking in aesthetics, and unable to meet some specific application scenarios or user needs. In addition, due to the relative position problem of the light source and the light guide axis, the traditional luminous potentiometer has a poor lighting effect. Therefore, a luminous potentiometer is proposed to solve the above problems. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a light-emitting potentiometer, aiming to improve the problems of the traditional light-emitting potentiometer in the prior art, such as relatively large overall volume, single light-emitting color and poor light-emitting effect.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a light-emitting potentiometer, including a light-guiding axis, the outer wall of the light-guiding axis is rotatably connected to a shell, a rivet is fixedly connected inside the shell, a resistor body is fixedly connected to the outer wall of the rivet, a resistor sheet is fixedly connected inside the resistor body, a light-emitting lamp body is fixedly connected to the outer wall of the rivet, a lamp board is fixedly connected inside the light-emitting lamp body, a patch LED lamp is fixedly connected to one side of the outer wall of the lamp board, a cover sheet is fixedly connected to the outer wall of the rivet, a brush is fixedly connected to the top of the light-guiding axis, a switch assembly is fixedly connected to one side of the outer wall of the light-emitting lamp body, and guide assemblies are arranged on both sides of the outer wall of the resistor body;

[0007] As a further description of the above technical solution: the guide assembly includes a guide cone 1 and a guide cone 2, and the outer walls of the guide cone 1 and the guide cone 2 are both fixedly connected to the inside of the resistor body;

[0008] As a further description of the above technical solution: the lamp board and the resistor and the top of the switch component are all fixedly connected with pins.

[0009] The utility model has the following beneficial effects:

[0010] 1. In the utility model, through the coordination among the light guide axis, shell, rivet, brush, resistor body, resistor sheet, lamp board, luminous lamp body, SMD LED lamp, switch assembly and cover sheet, the potentiometer is smaller in size while providing a more diverse selection of SMD LED lamp colors, thus solving the problems of relatively large overall size, single luminous color and poor luminous effect of traditional luminous potentiometer and enhancing the aesthetics.

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] Reference Figure 1 - Figure 3The utility model provides an embodiment: a light-emitting potentiometer, including a light-guiding axis 1, characterized in that: the outer wall of the light-guiding axis 1 is rotatably connected to a shell 2, a rivet 3 is fixedly connected inside the shell 2, a resistor body 4 is fixedly connected to the outer wall of the rivet 3, a resistor sheet 5 is fixedly connected inside the resistor body 4, a switch assembly 7 is fixedly connected to the outer wall of the rivet 3, a light-emitting lamp body 14 is fixedly connected to the outer wall of the rivet 3, a lamp board 6 is fixedly connected inside the light-emitting lamp body 14, a patch LED lamp 8 is fixedly connected to one side of the outer wall of the lamp board 6, a cover sheet 9 is fixedly connected to the outer wall of the rivet 3, and a brush 12 is fixedly connected to the top of the light-guiding axis 1.

[0018] Specifically, when the light-emitting potentiometer is used, when the output voltage needs to be changed, the light-guiding axis 1 is first rotated, and then the light-guiding axis 1 drives the brush 12 to rotate, and the brush 12 contacts the resistor 5 to form a moving contact. By rotating the brush 12, the moving contact of the brush 12 on the resistor 5 is changed, thereby adjusting its resistance value, thereby changing the voltage and current. When in use, the SMD LED lamp 8 can improve the color selection according to the design or customer needs. This light-emitting potentiometer has several forms that can be combined. First, it can be a stacked combination of one or more resistor bodies 4, and then a light-emitting lamp body 14 is fixedly connected to the bottom of the resistor body 4. Secondly, it can be a stacked combination of one or more resistor bodies 4, and then one or more switch components 7 are connected to the tail of the resistor body 4, and then at the bottom of the switch component 7 A light-emitting lamp body 14 is fixedly connected, and the chip LED lamp 8 is small in size. Compared with the monochrome light-emitting of traditional potentiometers, the potentiometer can emit colored light. It is easy to assemble, more convenient, beautiful, small in size, easy to produce, low in cost, and fast in patch efficiency, which makes the overall volume more compact. Compared with traditional monochrome LED potentiometers, it effectively saves space and provides greater flexibility and freedom for the design of electronic products. Secondly, the light-emitting potentiometer enables the product to have richer light options, thereby meeting the different needs of users for visual experience, and adding a new dimension to the functionality and practicality of the product. The feature that the light-emitting lamp body 14 can be added to the multi-resistor body or the switch component 7 at the end further enhances the scalability and applicability of the product to achieve more complex functions.

[0019] Reference Figure 1 - Figure 3 The guide assembly includes a guide cone 10 and a guide cone 2 11, the outer walls of the guide cone 10 and the guide cone 2 11 are fixedly connected to the inside of the resistor body 4, the top of the lamp board 6 and the resistor sheet 5, and the switch assembly 7, all of which are fixedly connected with a pin 13;

[0020] Specifically, when assembling the light-emitting potentiometer, the guide cone 10 can guide the housing 2 to be connected to the resistor body 4 in a relatively correct position, and the guide cone 2 11 can guide the switch assembly 7 to be connected to the resistor body 4 and the light-emitting lamp body 14 .

[0021] Working principle: When using the luminous potentiometer, first connect the power supply connecting line to the pin 13 of the luminous lamp body 14. At this time, the lamp board 6 in the luminous lamp body 14 lights up and stays on, and then the light is diffused through the light guide axis 1. At this time, by rotating the light guide axis 1, the switch component 7 is turned on, and then the light guide axis 1 drives the brush 12 to rotate, changing the position of the moving contact of the brush 12 on the resistor, thereby changing the resistance value between the moving contact and any fixed end, and then changing the voltage and current.

[0022] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
