Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings so that those skilled in the art can easily carry out the present invention.

These embodiments are to be considered as illustrative and not restrictive, as a person skilled in the art can implement various different embodiments.

FIG. 2 is an exploded perspective view of a fully charged filling inlet of an electric vehicle according to an embodiment of the present invention, which includes a housing 12, a plurality of terminals 20 inserted into the housing 12, And a rear grommet 14 coupled to an end of the housing 12 so that the terminal holder 18 and the rear grommets 14 are connected to each other, The LED driver 100 having the LED (Light Emitting Diode) mounted therein is inserted.

The LED driving part 100 includes a prism part 115 inserted into the housing 12, a PCB plate 130 coupled to the lower part of the lower lens 120 and inserted with a plurality of LEDs to emit light, And an LED holder 140 in which the PCB plate 130 is mounted to the mounting groove 145.

The prism portion 115 includes an upper lens 110 as a clear lens and a lower lens 120 as an opaque lens including a diffusing agent combined with the upper lens 110, The upper lens 110 and the lower lens 120 are spaced apart from each other by a predetermined distance such that the protrusions 125 of the lower lens 120 and the grooves 114 of the upper lens 110 The thickness of the upper lens 110 is greater than the predetermined distance and the thickness of the lower lens 120 is greater than the thickness of the upper lens 110. [

If the thickness of the lower lens 120 is smaller than the thickness of the upper lens 110, light passing through the lower lens 120 is scattered to cause the light to wave. This occurs irrespective of the uniformity of the upper lens 110 do.

If the predetermined distance is greater than the thickness of the upper lens 110, the brightness of light passing through the upper lens 110 is reduced.

5B shows a case where the upper lens 110 is a clear lens and the lower lens 120 is an opaque lens. Light emitted through the PCB plate 130 passes through an opaque lens including a diffusing agent, To interfere with the straightness of the light, which causes the light to be evenly distributed throughout the lens. Moreover, the clear lens is displayed more clearly while passing through the lens, thereby improving the visibility of the driver.
