Abstract
A vehicle lamp has light sources having light emitting diodes that are vertically and horizontally disposed in the form of a square. A first LED group is disposed in the central position of the light source and is turned on in the tail lamp lighting mode. A second LED group surrounds the first LED group, and is turned on together with the first LED group in the stop lamp lighting mode. Thus, the light source appears as if the LEDs became luminous around the central position of the light source in any lamp lighting mode.
Claims20
A vehicle lamp comprising:
- a lamp unit including a plurality of light sources having a plurality of LEDs that can be turned on in at least two kinds of lamp lighting modes;
- each of said light sources being provided with a first LED group comprising at least one LED disposed in a substantially central position of said light source and a second LED group comprising a plurality of LEDs surrounding said first LED group, said first and said second LED groups being mutually exclusive;
- and
- said lamp lighting modes comprising a first lamp lighting mode wherein only said first LED groups of all of said light sources are turned on simultaneously, and a second lamp lighting mode wherein said second LED groups of all of said light sources are turned on.
A vehicle lamp comprising:
- a lamp unit including a plurality of light source means having a plurality of LEDs that can be turned on in at least two kinds of lamp lighting modes;
- each of said light source means being provided with a first LED group comprising at least one LED disposed in a substantially central position of said light source means and a second LED group comprising a plurality of LEDs surrounding said first LED group, said first and said second LED groups being mutually exclusive;
- and
- said lamp lighting modes comprising a first lamp lighting mode wherein only said first LED groups of all of said light source means are turned on simultaneously, and a second lamp lighting mode wherein said second LED groups of all of said light source means are turned on.
A vehicle lamp having a plurality of lamp lighting modes, said vehicle lamp comprising:
- a first light source being provided with a first LED group comprising at least one LED disposed in a substantially central position of said first light source and a second LED group comprising a plurality of LEDs surrounding said first LED group;
- a second light source being provided with a third LED group comprising at least one LED disposed in a substantially central position of said second light source and a fourth LED group comprising a plurality of LEDs surrounding said third LED group;
- and
- said plurality of lamp lighting modes comprise a first lamp lighting mode wherein only said first and third LED groups are turned on, a second lamp lighting mode wherein said first and second LED groups are turned on, and a third lamp lighting mode where said third LED group is turned off and said fourth LED group is turned on intermittently.
