Abstract
Abstract An optoelectronic unit includes a base plate, an optoelectronic component carried by the base plate and having at least one optically active zone, and a lens body having at least one lens associated with the at least one optically active zone. The lens body has an integral spacing device resting directly against the optoelectronic component for establishing a desired clearance distance between the at least one optically active zone and the at least one lens.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
92 words
An optoelectronic unit, comprising: a base plate; an optoelectronic component carried by said base plate and having a length, a substantially flat surface extending entirely along said length and at least one optically active zone; and a lens body having at least one lens associated with said at least one optically active zone, said lens body having an integral spacing device resting directly against said substantially flat surface of said optoelectronic component for establishing a desired clearance distance between said at least one optically active zone and said at least one lens.
Claim 2
Dependent Claim
92 words
An optoelectronic unit, comprising: a base plate; an optoelectronic component carried by said base plate and having a length, a substantially flat surface extending entirely along said length and at least one optically active zone; and a lens body having at least one lens associated with said at least one optically active zone, said lens body having an integral spacing device resting directly against said substantially flat surface of said optoelectronic component for establishing a desired clearance distance between said at least one optically active zone and said at least one lens.
Claim 3
Dependent Claim
37 words
The unit according to claim 1, wherein said spacing device includes studlike protuberances having a height dimensioned in accordance with said desired spacing between said at least one optically active zone and said at least one lens.
Claim 4
Dependent Claim
11 words
The unit according to claim 2, wherein said protuberances are lenticular.
Claim 5
Dependent Claim
33 words
The unit according to claim 2, wherein said at least one lens has an optical axis in a given plane, and each of said protuberances has its highest point in said given plane.
Claim 6
Dependent Claim
25 words
The unit according to claim 1, wherein said lens body is formed of a material, and said spacing device includes protuberances formed in said material.
Claim 7
Dependent Claim
45 words
The unit according to claim 1, wherein said at least one optically active zone has a given height, and said lens body is fixed on said base plate and has a height causing said at least one lens to be aimed at said given height.
Claim 8
Dependent Claim
58 words
The unit according to claim 1, wherein said at least one optically active zone is a given number of optically active zones disposed in a row, said at least one lens of said lens body is at least said given number of lenses disposed in a row, and said spacing device is disposed in line with said lenses.
Claim 9
Dependent Claim
68 words
