Since this assembly structure is general, its detailed description is omitted.

Hereinafter, another embodiment of a lamp knob switch of the present invention will be described with reference to the drawings.

9 is an exploded perspective view illustrating an exploded view of a switch knob according to another embodiment of the present invention. As illustrated, the transparent sheet 210 having the printable surface on the top surface of the backlight unit 200 is sequentially assembled. The switch knob 110 and the power input from the outside may constitute a lamp knob switch including a switch module 160 for switching on and off the power supplied to the backlight unit 200 by the rotation of the switch knob 110. have.

In the present invention, when the transparent sheet 210 is used as a protective plate of the backlight unit 200 may be used by combining another transparent sheet 210 on the upper surface of the protective plate.

In the embodiment of FIG. 9, the backlight unit is configured in an edge type, and the edge type backlight unit includes a light source 240, a reflecting plate 230, a light guide plate 260, a reflecting unit 270, a prism plate 220, and a protective plate 210. ), And the light incident part 250 may be configured.

The light sources 240 are made of light emitting diodes (LEDs) and the like, and are arranged in a line at predetermined intervals along the light incidence unit 250, which is one side of the light guide plate 260, and emit light according to a control signal. Light is incident on the light guide plate 260 through 250.

The reflective plate 230 reflects and condenses the light emitted from the light source 240 to be incident on the light incident part 250, which is one side of the light guide plate 260, without leaking to the outside.

That is, the light generated from the light source 240 directly enters the light incident part 250 or is reflected and collected by the reflector 230 to enter the light incident part 250 of the light guide plate 260.

Here, the light incident part 250 is also referred to as a "mirror part", and in the description of the present invention, it is used interchangeably when necessary according to the context. The mirrored state is a mirror-like flat state without irregularities.

The light guide plate 260 is uniform by repeating total reflection and refraction inside the light incident from the light source 240 installed at the light incident part 250, which is one edge, to a point light source or a line light source. And output to the upper and lower surfaces after conversion into a face light source of luminance.

The light guide plate 260 generally uses an acrylic resin (PMMA: Poly-Methyl-Methacrylate, polymethyl methacrylate) having excellent transparency, good weatherability, high hardness, and excellent surface glossiness. It is resistant to weak acids, invasive to alkalinity, soluble in organic solvents, weak in shock and deformable at 100 degrees Celsius.

In this case, the light incident part 250 functions to transmit the light incident from the light source 240 into the light guide plate 260.

The reflector 270 is positioned on the lower surface of the light guide plate 260 and reflects the light of the surface light source emitted to the lower surface and is incident to the lower surface of the light guide plate 260. That is, the light guide plate 260 emits the surface light source only to the upper surface.

The prism plate 220 is positioned on the upper surface of the light guide plate 260 and condenses and diffuses (scatters) the incident light in order to improve the brightness and uniformity of the light emitted to the upper surface, and emits in the direction in which the protective plate 210 is located. .

The protection plate 210 is positioned on the upper surface of the prism plate 220 to buffer physical shocks applied from the outside, so that the protection plate 210 is configured to protect the prism plate 220 and the light guide plate 260, and at the same time, the transparent sheet 130 and Likewise, various colors of highlighter can be used to allow the user to write their own identifiable letters.

The prism plate 220 and the protection plate 210 may be integrally formed with the light guide plate 260.

In this case, by replacing the transparent sheet 130, which is replaceable on the upper surface of the protective plate 210, the recognition letters can be written so as to have an interior effect.

In this configuration, the light generated from the light source 240 is incident to the inside of the light guide plate 260 through the light incidence part 250, is scattered in the light guide plate 260, converted into a surface light source, and is emitted to a designated surface. It may be used as a backlight of the transparent sheet 130 that is a display device.

When the LED is configured as a backlight unit as described above, it is a matter of course that not only the edge type backlight but also the direct type backlight can be configured without any particular difficulty.

Meanwhile, in the light guide plate 260, light is provided by the light source 240, and the light is transmitted through the side surface of the acrylic into the light guide plate 260. In this case, a predetermined amount of light provided by the light source 240 is provided on the acrylic surface. The light reflects off and the rest of the light goes into the acrylic.

Since the amount of light that enters the inside of the acrylic decreases more and more due to the light transmittance of the acrylic itself, the thicker the light guide plate in the same light source, the greater the angle of incidence from the light guide plate, the greater the amount of light entering the light guide plate, and the distance the light is reflected. In addition, the greater the thickness of the light guide plate, the greater the amount of light therein.

In order to reflect the light quantity on the surface of the LGP with the same amount of light, the reflector reflecting the light is made small in the vicinity of the light source having a relatively high amount of light. On the side, the reflector reflecting light is formed large, so that although the amount of light is small, the amount of light emitted toward the front of the light guide plate is large to balance the amount of light emitted from the light guide plate as a whole.

That is, in the light guide plate 260, a unique reflector is formed on the back surface of the light guide plate 260 by printing or V-cutting to effectively reflect light incident from the light source 240.

The pattern design of the printing method is to increase the amount of light reflected from the dot by increasing the size of the dot as it moves away from the light source. In the V-cutting method, the V is moved away from the light source. It is preferable to use a method of reducing the gap of the mold groove or increasing the depth thereof.

In this case, the switch knob 110 may be configured to further include an optical sensor module 180 to control the power supplied to the LED to be switched on and off according to the data output from the optical sensor 182.

According to the lamp knob switch of the present invention as described above, by using the LED light source can be a simple activity at night only by lighting the light switch knob portion without large power consumption, and can be rewritten at any time when the expression position or user changes In addition to user convenience, there is an effect that can maximize the interior effect.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art.
