Abstract
Abstract An illuminating device has a bar-shaped light, a light conductor plate and a U-shaped clamping part having two legs. The clamping part extends along the bar-shaped light and connects the light with the light conductor plate so that the clamping part embraces the light and a neighboring edge region of the light conductor plate in a U-shaped manner and the legs are elastically fixed on the light conductor plate.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
130 words
An illuminating device, comprising a bar-shaped light; a light conductor plate; and a U-shaped clamping part having two legs, said clamping part extending along said bar-shaped light and connecting said light with said light conductor plate so that said clamping part embraces said light and a neighboring edge region of said light conductor plate in a U-shaped manner and said legs are elastically fixed on said light conductor plate, said clamping part having a first engaging formation provided on said legs, said light conductor plate having second engaging formations formed so that said first engaging formations engage with said second engaging formations, one of said first and second engaging formations being a projection, while another of said first and second engaging formations is a groove in which said projection engages.
Claim 2
Dependent Claim
130 words
An illuminating device, comprising a bar-shaped light; a light conductor plate; and a U-shaped clamping part having two legs, said clamping part extending along said bar-shaped light and connecting said light with said light conductor plate so that said clamping part embraces said light and a neighboring edge region of said light conductor plate in a U-shaped manner and said legs are elastically fixed on said light conductor plate, said clamping part having a first engaging formation provided on said legs, said light conductor plate having second engaging formations formed so that said first engaging formations engage with said second engaging formations, one of said first and second engaging formations being a projection, while another of said first and second engaging formations is a groove in which said projection engages.
Claim 3
Dependent Claim
94 words
An illuminating device, comprising a bar-shaped light; a light conductor plate; a U-shaped clamping part having two legs, said clamping part extending along said bar-shaped light and connecting said light with said light conductor plate so that said clamping part embraces said light and a neighboring edge region of said light conductor plate in a U-shaped manner and said legs are elastically fixed on said light conductor plate, said bar-shaped light having two ends; and means forming a U-shaped recess provided at each of said ends and receiving a respective one of said ends.
Claim 4
Dependent Claim
94 words
An illuminating device, comprising a bar-shaped light; a light conductor plate; a U-shaped clamping part having two legs, said clamping part extending along said bar-shaped light and connecting said light with said light conductor plate so that said clamping part embraces said light and a neighboring edge region of said light conductor plate in a U-shaped manner and said legs are elastically fixed on said light conductor plate, said bar-shaped light having two ends; and means forming a U-shaped recess provided at each of said ends and receiving a respective one of said ends.
Claim 5
Dependent Claim
125 words
An illuminating device, comprising a bar-shaped light having two ends; a light conductor plate having a longitudinal edge which is spaced from said light; a U-shaped clamping part having two legs, said clamping part extending along said bar-shaped light and connecting said light with said light conductor plate so that said clamping part embraces said light and a neighboring edge region of said light conductor plate in a U-shaped manner and said legs are elastically fixed on said light conductor plate; means forming a U-shaped recess provided at each of said ends and receiving a respective one of said ends of said light; and means forming abutment members provided in said housing so that said longitudinal edge of said plate abuts against said abutment members.
Claim 6
Dependent Claim
125 words
An illuminating device, comprising a bar-shaped light having two ends; a light conductor plate having a longitudinal edge which is spaced from said light; a U-shaped clamping part having two legs, said clamping part extending along said bar-shaped light and connecting said light with said light conductor plate so that said clamping part embraces said light and a neighboring edge region of said light conductor plate in a U-shaped manner and said legs are elastically fixed on said light conductor plate; means forming a U-shaped recess provided at each of said ends and receiving a respective one of said ends of said light; and means forming abutment members provided in said housing so that said longitudinal edge of said plate abuts against said abutment members.
Claim 7
Dependent Claim
102 words
An illuminating device, comprising a bar-shaped light; a light conductor plate; and a U-shaped clamping part having two legs, said clamping part extending along said bar-shaped light and connecting said light with said light conductor plate so that said clamping part embraces said light and a neighboring edge region of said light conductor plate in a U-shaped manner and said legs are elastically fixed on said light conductor plate, said clamping part having a first engaging formation provided on said legs, said light conductor plate having second engaging formations formed so that said first engaging formations engage with said second engaging formations.
Claim 8
Dependent Claim
102 words
An illuminating device, comprising a bar-shaped light; a light conductor plate; and a U-shaped clamping part having two legs, said clamping part extending along said bar-shaped light and connecting said light with said light conductor plate so that said clamping part embraces said light and a neighboring edge region of said light conductor plate in a U-shaped manner and said legs are elastically fixed on said light conductor plate, said clamping part having a first engaging formation provided on said legs, said light conductor plate having second engaging formations formed so that said first engaging formations engage with said second engaging formations.
Claim 9
Dependent Claim
98 words
An illuminating device, comprising a bar-shaped light; a reflecting foil; a light conductor plate; and a U-shaped clamping part having two legs, said clamping part extending along said bar-shaped light and connecting said light with said light conductor plate so that said clamping part embraces said light, said reflecting foil and a neighboring edge region of said light conductor plate in a U-shaped manner and said legs are elastically fixed on said light conductor plate; and a housing provided with a plurality of projections spaced from one another to receive said bar-shaped light, and said light conductor plate.
Claim 10
Dependent Claim
98 words
An illuminating device, comprising a bar-shaped light; a reflecting foil; a light conductor plate; and a U-shaped clamping part having two legs, said clamping part extending along said bar-shaped light and connecting said light with said light conductor plate so that said clamping part embraces said light, said reflecting foil and a neighboring edge region of said light conductor plate in a U-shaped manner and said legs are elastically fixed on said light conductor plate; and a housing provided with a plurality of projections spaced from one another to receive said bar-shaped light, and said light conductor plate.
Claim 11
Dependent Claim
90 words
An illuminating device as defined in claim 1, wherein each of said engaging grooves has a substantially vertical abutment surface, one of said engaging projections extending in a direction away from said light, while another of said engaging formations extend in direction toward said light, so that when said engaging formations engage in said engaging grooves they abut against said abutment surfaces to prevent a displacement of said light relative to said light conductor plate both in the direction away of said light and in a direction towards said light.
