Abstract

An automotive lamp provides information to vehicles approaching from at least one side of the rear of a vehicle of the driving state of the vehicle by irradiating light for forming a road pattern indicating the driving state of the vehicle. The automotive lamp includes a detection unit configured to detect a driving state of a vehicle, a reversing lamp configured to indicate a reverse movement of the vehicle, a lamp unit configured to irradiate light for forming a road pattern indicating the state of the vehicle to the rear of the vehicle such that the road pattern can be formed on at least one side of the vehicle. A control unit is configured to control the lamp unit based on the detected driving state of the vehicle. The luminous intensity of the lamp unit is equal to, or greater than, the luminous intensity of the reversing lamp.

First claim

What is claimed is:

1 . An automotive lamp, comprising:
a detection unit configured to detect a driving state of a vehicle; a reversing lamp configured to indicate a reverse movement of the vehicle; a lamp unit configured to irradiate light that forms a road pattern indicating the driving state of the vehicle to the rear of the vehicle and forms the road pattern on at least one side of the vehicle; and a control unit configured to control the lamp unit based on the detected driving state of the vehicle, wherein the luminous intensity of the lamp unit is equal to, or greater than, the luminous intensity of the reversing lamp.

2 . The automotive lamp of claim 1 , wherein the driving state of the vehicle includes a reverse movement of the vehicle.

3 . The automotive lamp of claim 1 , wherein the luminous intensity of the lamp unit is about 4,300 cd to 13,000 cd.

4 . The automotive lamp of claim 1 , wherein the lamp unit and the reversing lamp are disposed in one of a plurality of spaces, which are defined by a plurality of lamps for different purposes, and the lamp unit shares, with the reversing lamp, a lens that corresponds to the space where the reversing lamp is disposed, or has a lens of the same color as the reversing lamp.

5 . The automotive lamp of claim 1 , wherein the control unit is configured to simultaneously turn on or off the reversing lamp and the lamp unit.

6 . The automotive lamp of claim 1 , wherein the reversing lamp includes a plurality of light source components and the control unit is configured to turn off the lamp unit when at least one of the light source components of the reversing lamp is turned off.

7 . The automotive lamp of claim 1 , wherein the lamp unit is turned off when an ambient brightness is greater than a reference brightness.

8 . The automotive lamp of claim 1 , wherein a horizontal irradiation angle and a vertical irradiation angle of the lamp unit are acute angles.

9 . The automotive lamp of claim 8 , wherein the horizontal irradiation angle of the lamp unit is 20 degrees to 45 degrees.

10 . The automotive lamp of claim 8 , wherein the vertical irradiation angle of the lamp unit is 15 degrees to 45 degrees.

11 . The automotive lamp of claim 1 , wherein the road pattern includes a plurality of irradiation patterns, which are circular, and the irradiation patterns have the same size or different sizes.

12 . An automotive lamp, comprising:
a detection unit configured to detect a driving state of a vehicle; and lamp units configured to irradiate light that forms a road pattern indicating the driving state of the vehicle to the rear of the vehicle, the lamp units disposed on both sides of the rear of the vehicle and irradiating light that forms a plurality of road patterns on both sides of the rear of the vehicle.

13 . The automotive lamp of claim 12 , wherein the detection unit is configured to detect whether a rear shift stage is selected.

14 . The automotive lamp of claim 12 , wherein the two road patterns are symmetrical with each other with respect to a central line of the vehicle.

15 . The automotive lamp of claim 12 , wherein each of the two road patterns includes a plurality of irradiation patterns, which are circular, and the area of an irradiation pattern more distant than a neighboring irradiation pattern from the vehicle is 1.2 to 2 times the area of the neighboring irradiation pattern.

16 . The automotive lamp of claim 15 , wherein each of the irradiation patterns has different brightnesses from a central area to an edge area thereof.

17 . The automotive lamp of claim 15 , wherein each of the irradiation patterns is brighter in the central area than in the edge area thereof.

18 . The automotive lamp of claim 12 , wherein the luminous intensity of the lamp units is 4,300 cd to 13,000 cd.

19 . The automotive lamp of claim 12 , wherein the horizontal irradiation angle of the lamp units is 20 degrees to 45 degrees.

20 . The automotive lamp of claim 12 , wherein the vertical irradiation angle of the lamp units is 15 degrees to 45 degrees.
