Abstract
Abstract In a rear combination lamp assembly (10) for a vehicle, a plurality of LEDs (16) capable of being turned on and off independently of each other are mounted on a first printed circuit board (13). A plate-like lens element (12) and a second printed circuit board (14) are arranged with the first printed circuit board (13) located between them. A control circuitry (17) is mounted on the second printed circuit board (14), for selectively turning on and off the LEDs (16) to display various patterns on a matrix display (18) formed by the LEDs (16). The first printed circuit board (13), the lens element (12) and the second printed circuit board (14) are held in a united fashion.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
171 words
A rear combination lamp assembly for a vehicle, characterized by comprising: a first printed circuit board (13) having mounted thereon a plurality of LEDs (16) capable of being turned on and off independently of each other, said LEDs (16) cooperating with each other to form a matrix display (18); a plate-like lens element (12) arranged substantially in parallel relation to said first printed circuit board (13) and in front of the same to cover said LEDs (16); a second printed circuit board (14) arranged on the opposite side of said first printed circuit board (13) from said lens element (12) and substantially in parallel relation to said first printed circuit board (13), said second printed circuit board (14) having mounted thereon control circuit means (17) for selectively turning on and off said LEDs (16) to display various patterns on said matrix display (18); and holding means (11, 15) for holding said first printed circuit board (13), said lens element (12) and said second printed circuit board (14) in a united fashion.
Claim 2
Dependent Claim
171 words
A rear combination lamp assembly for a vehicle, characterized by comprising: a first printed circuit board (13) having mounted thereon a plurality of LEDs (16) capable of being turned on and off independently of each other, said LEDs (16) cooperating with each other to form a matrix display (18); a plate-like lens element (12) arranged substantially in parallel relation to said first printed circuit board (13) and in front of the same to cover said LEDs (16); a second printed circuit board (14) arranged on the opposite side of said first printed circuit board (13) from said lens element (12) and substantially in parallel relation to said first printed circuit board (13), said second printed circuit board (14) having mounted thereon control circuit means (17) for selectively turning on and off said LEDs (16) to display various patterns on said matrix display (18); and holding means (11, 15) for holding said first printed circuit board (13), said lens element (12) and said second printed circuit board (14) in a united fashion.
Claim 3
Dependent Claim
50 words
A rear combination lamp assembly according to claim 1, characterized in that said lens element (12) has a plurality of lens sections (12a) corresponding respectively to said LEDs (16), each of said lens sections (12a) being adapted to disperse light from a corresponding one of said LEDs (16) substantially uniformly.
Claim 4
Dependent Claim
76 words
A rear combination lamp assembly according to claim 1 or 2, characterized in that said holding means comprises a rear cover (15) and a front cover (11) through which lights from the respective LEDs (16) can be transmitted, said rear cover (15) and said front cover (11) cooperating with each other to form a housing in which said first printed circuit board (13), said lens element (12) and said second printed circuit board (14) are accommodated.
Claim 5
Dependent Claim
83 words
