Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
72 words
A lighting apparatus, comprising a light source and a light control lens in close disposition to the outer surface of the light source so as to cover at least a part thereof directly, the light control lens being so shaped to have such a three-dimensional configuration as to control the luminous flux coming out of the light source and passing therethrough to have a predetermined light flux distribution and range of incidence.
Claim 2
Dependent Claim
72 words
A lighting apparatus, comprising a light source and a light control lens in close disposition to the outer surface of the light source so as to cover at least a part thereof directly, the light control lens being so shaped to have such a three-dimensional configuration as to control the luminous flux coming out of the light source and passing therethrough to have a predetermined light flux distribution and range of incidence.
Claim 3
Dependent Claim
95 words
The lighting apparatus as defined in Claim 1, wherein the sectional shape of the light control lens taken along a plane including the luminous flux coming out of the light source and passing through the light control lens has a pair of swelled portions protruding in the direction away from the light source on two opposed sides of the same, and a recessd portion provided on the side counter to the light source between the swelled portions, the swelled portions and the recessed portion having a shape bounded and defined by a smoothly continuous curve.
Claim 4
Dependent Claim
91 words
The lighting apparatus as defined in Claim 1, wherein the sectional shape of the light control lens taken along a plane including the luminous flux coming out of the light source and passing through the light control lens has a pair of side portions extending along the light source on two opposed sides of the same, and a projected portion disposed on the side counter to the light source between the side portions, the side portions and the projected portion having a shape bounded and defined by a smoothy continuous curve.
Claim 5
Dependent Claim
24 words
The lighting apparatus as defined in Claim 1, wherein the surface of the light control lens facing the light source is a Fresnel surface.
Claim 6
Dependent Claim
28 words
The lighting apparatus as defined in Claim 1, wherein the surface of the light control lens on the side counter to the light source is a Fresnel surface.
Claim 7
Dependent Claim
51 words
The lighting apparatus as defined in Claim 1, wherein the light source is cylindrical, and the light control lens has a shape which substantially covers a semicylindrical surface on one side of the light source with respect to an imaginary plane passing through the longitudinal central axis of the light source.
Claim 8
Dependent Claim
33 words
The lighting apparatus as defined in Claim 1, wherein the light source is substantially spherical, and the light control lens has a shape to cover a substantially semispherical surface of the light source.
Claim 9
Dependent Claim
27 words
The lighting apparatus as defined in Claim 1, wherein a slight clearance is formed between the light control lens and the outer surface of the light source.
Claim 10
Dependent Claim
24 words
The lighting apparatus as defined in Claim 1, wherein the light control lens is fixed on the light source through fitting on the latter.
