## Abstract

An illuminated door sill plate contains: a base and a removable cover. The base includes an elongated case, a waterproof plate, a PCB having a light-emitting diode (LED), a light guide plate, and at least one changeable battery. The elongated case has a light emitting portion, multiple engagement portions, at least one first receiving orifice, and at least one battery cover. The removable cover includes an elongated body connected with a nameplate, and the nameplate has a light transmission portion formed on center of the nameplate in multiple character shapes and configured to transmit lights, an elongated groove formed on center of a top of the elongated body, and multiple hooks extending from two long sides of the elongated groove and engaged with the multiple engagement portions so that the base is connected with or removed from the removable cover.

## Claims

### Claim 1

An illuminated door sill plate comprising:
a base including an elongated case and a waterproof plate connected with a bottom of the elongated case so as to form an accommodation space between the elongated case and the waterproof plate, a PCB accommodated in the accommodation space and having a light-emitting diode (LED), a light guide plate between the elongated case and the PCB, and at least one changeable battery, wherein the elongated case has a light emitting portion arranged on the elongated case, multiple engagement portions arranged on two long sides of the elongated case, at least one first receiving orifice defined proximate to two short sides of a top of the elongated case, and at least one battery cover configured to cover the at least one first receiving orifice; and
a removable cover including an elongated body connected with a nameplate, and the nameplate including a light transmission portion formed on center of the nameplate in character shapes and configured to transmit lights, an elongated groove formed on center of a top of the elongated body, and multiple hooks extending from two long sides of the elongated groove and engaged with the multiple engagement portions so that the base is connected with or is removed from the removable cover;
wherein two ends of the removable cover accommodate two magnets so as to be attached on a car door threshold.

### Claim 2 (depends on 1)

The illuminated door sill plate as claimed in claim 1, wherein the elongated body of the removable cover has a stepped face formed on the top thereof, two notches defined adjacent to two short sides of the top of the elongated body, and the respective notch is located adjacent to a respective short side of the elongated body and accommodates a respective magnet attached by the nameplate.

### Claim 3 (depends on 1)

The illuminated door sill plate as claimed in claim 1, wherein the nameplate is made of metal, the light transmission portion of the nameplate passes through the holes or shape on the nameplate, and the lights emit out of the light transmission portion from the light emitting portion of the elongated case in three-dimensional character shapes.

### Claim 4 (depends on 1)

The illuminated door sill plate as claimed in claim 1, wherein the nameplate is made of translucent plastic, the light transmission portion passes through the nameplate by in form of a shading printing manner, such that the lights emit out of the light transmission portion from the light emitting portion of the elongated case in flat character shapes.

### Claim 5 (depends on 1)

The illuminated door sill plate as claimed in claim 1, wherein the removable cover includes two guide posts, and a respective guide post extends from the bottom of the elongated body and is located proximate to a respective short side of the bottom of the elongated body.

### Claim 6 (depends on 1)

The illuminated door sill plate as claimed in claim 1, wherein a bottom of the base is fixed on the car door threshold of the vehicle.
