The present invention relates to an internal lighting device of a volume knob, and more particularly, to emit light emitted to the outside through a volume knob that controls an audio-visual system using a shaft type encoder. The present invention relates to an internal lighting device of a volume knob that provides a structure that can reduce the number of light emitting diodes (LEDs) in a light source chain evenly.

In general, the driver of the vehicle informs the position of the AV device during night driving, or forms a semi-transparent reflector on the outer circumferential surface of the volume knob that adjusts the AV device in order to improve design sensitivity quality. Illumination from the LED was emitted along the outer circumferential surface of the volume knob through the reflector.

This shows the state diagram delivered along.

As shown in FIG. 1, in the conventional lighting device of the volume knob, four LEDs 20a are disposed around the encoder 10a, and the reflector 40a is mounted on the encoder 10a. It is located inside the front panel 30a of the device.

The volume knob 50a has an outer diameter smaller than the inner diameter of the reflector 40a, and the volume knob 50a is seated on the inner surface of the reflector 40a (see Fig. 2).

Therefore, in order for the reflector 40a to be formed large so that the light emitted from the LED 20a is uniformly emitted along the outer circumferential surface of the volume knob 50a, at least three to four or more LEDs must be disposed. There was a problem that the unit price increases.

In addition, an illumination spot phenomenon occurs in which the light emitted from the LED 20a is concentrated at a specific site (see FIG. 3), and to solve this, a cover sheet for scattering and dispersing a separate LED light is required. There was a cumbersome problem in the design and assembly of the product.

The present invention has been made to solve the above problems, an object of the present invention is to firstly reduce the number of products of the light source chain LED that emits light along the outer circumferential surface of the volume knob to reduce the unit cost of the product, and In addition, while reducing the number of LEDs and providing a structure that allows the illumination to be uniformly distributed along the outer circumferential surface of the volume knob through the reflector, and thirdly, it is easy for the driver of the vehicle to adjust the AV device at night driving. It is to provide a structure that can improve the emotional quality of the product by providing a uniform illumination along the outer peripheral surface of the volume knob.

In order to achieve the above object, the present invention provides an encoder installed on a PCB, LEDs respectively disposed on both sides of the encoder, a front panel formed with a hollow hole on one side while covering the encoder, and inserted into the hollow hole to the front surface. A reflector having an illumination viewer configured to be supported by the panel and to emit the light emitted from the LED to the outside, a cylindrical volume knob rotatable and one side open while surrounding the outer circumferential surface of the reflector, and the open volume knob It comprises a knob cover to cover.

In addition, in the present invention, the outer diameter of the reflector is preferably formed smaller than the inner diameter of the volume knob.

In addition, in the present invention, the light emitted from the LED is preferably emitted along the outer circumferential surface of the knob cover through the light viewing portion of the reflector.

As described above, the present invention has the effect of firstly reducing the cost by reducing the number of light source chain LEDs emitted along the outer circumferential surface of the volume knob and lowering the cost of the product, and secondly, reducing the number of LEDs. It is effective to make product design and manufacture easy. Third, it is possible to emit uniform light along the outer circumferential surface of the volume knob through the reflector to improve the quality of the product. There is an effect that it can be easily operated.

Hereinafter, the present invention will be described in detail with reference to the drawings.

Figure 4 is an exploded perspective view of the inner lighting device of the volume knob of the present invention, Figure 5 is a state diagram of the volume knob and the reflector of the present invention, Figure 6 is the illumination emitted from the LED in Figure 5 of the volume knob through the reflector It shows a state diagram transmitted along the outer peripheral surface.

As shown in FIG. 2, the present invention relates to an inner illumination device of a volume knob that is formed on one side of an AV device and controls an AV device, and includes an encoder 10, an LED 20, a front panel 30, and a reflector. 40, the volume knob 50, and the knob cover 60.

Encoder (10) is made of a shaft (shafr) shape is installed on a printed circuit board (PCB) formed electrical circuit (11) to detect that the rotation from the volume knob 50 at a certain angle It is a sensor that transmits the signal to the PCB (11).

The LEDs 20 are light sources that are arranged on the PCB 11 and are disposed on both sides of the encoder 10, respectively.

The front panel 30 is a case formed on the front of the AV device and includes a display device and a volume knob 50 of the AV device.

One side of the front panel 30 is provided with a hollow hole 31 formed in a cylindrical shape of a predetermined diameter.

The reflector 40 is seated and supported inside the AV device through the hollow hole 31 formed at one side of the front panel 30.

In addition, the reflector 40 receives an illumination emitted from the light source chain LED 20 disposed on both sides of the encoder 11 and scatters it so that the illumination viewer 41 emits along the inner circumferential surface of the volume knob 50. It is formed to protrude to a certain height.

Here, the illumination viewer 41 is formed in diameter to match the size of the outer diameter of the knob cover (60).

The volume knob 50 is formed in a cylindrical shape which is rotatable at a predetermined angle while being in contact with the outer circumferential surface of the reflector 40 and one surface is open.

Therefore, the outer diameter of the reflector 40 is formed smaller than the inner diameter of the volume knob 50.

Preferably, the outer diameter of the reflector 40 and the inner diameter of the volume knob 50 are the same.

Then, a circular knob cover 60 is formed to be fitted and fixed to the reflector 40 through an upper side of the volume knob 50 having one surface open.

In addition, the light emitted from the LED 20 is scattered through the reflector 40 and is emitted along the outer circumferential surface of the knob cover 60 through the lighting viewer 41 (see FIGS. 5 and 6).

Looking at the assembly process of the present invention made of these components are as follows.

First, the encoder 10 is installed on the PCB 11, and two LEDs 20 are disposed at positions symmetrical with respect to the encoder 10.

Then, the reflector 40 is inserted into the volume knob 50 and then coupled with the volume knob 50 through the knob cover 60.

The encoder 10 and the LED 20 installed on the PCB 11 are assembled at both sides of the volume knob 50 and the front panel 30 coupled with the reflector 40.
