Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
81 words
A reflector electric lamp comprising: a curved glass reflector; a sealed tungsten-halogen lamp disposed within the reflector; a metal eyelet extending through a hole in the reflector and fastened to the reflector, the inner end of the eyelet having an angled head thereon shaped to approximately conform to the reflector curvature; and a lead-in conductor, one end of which is connected to, and supports, the tungsten-halogen lamp, and the other end of which extends through, and is connected to, the eyelet.
Claim 2
Dependent Claim
81 words
A reflector electric lamp comprising: a curved glass reflector; a sealed tungsten-halogen lamp disposed within the reflector; a metal eyelet extending through a hole in the reflector and fastened to the reflector, the inner end of the eyelet having an angled head thereon shaped to approximately conform to the reflector curvature; and a lead-in conductor, one end of which is connected to, and supports, the tungsten-halogen lamp, and the other end of which extends through, and is connected to, the eyelet.
Claim 3
Dependent Claim
103 words
A reflector electric lamp comprising: a curved glass reflector a sealed tungsten-halogen lamp disposed within the reflector; a metal eyelet extending through a hole in the reflector and fastened to the reflector; and a lead-in conductor, one end of which is connected to, and supports, the tungsten-halogen lamp, and the other end of which extends through, and is connected to, the eyelet, said eyelet comprising at least a larger diameter portion and a smaller diameter portion, the larger diameter portion providing concentricity of the eyelet in the reflector hole, and the smaller diameter portion providing concentricity of the lead-in conductor in the eyelet.
Claim 4
Dependent Claim
103 words
A reflector electric lamp comprising: a curved glass reflector a sealed tungsten-halogen lamp disposed within the reflector; a metal eyelet extending through a hole in the reflector and fastened to the reflector; and a lead-in conductor, one end of which is connected to, and supports, the tungsten-halogen lamp, and the other end of which extends through, and is connected to, the eyelet, said eyelet comprising at least a larger diameter portion and a smaller diameter portion, the larger diameter portion providing concentricity of the eyelet in the reflector hole, and the smaller diameter portion providing concentricity of the lead-in conductor in the eyelet.
Claim 5
Dependent Claim
101 words
A reflector electric lamp comprising: a curved glass reflector having a predetermined thickness; a sealed tungsten-halogen lamp disposed within the reflector; a metal eyelet extending completely through a hole in the reflector and fastened to the reflector, there being a space between the eyelet and the sides of said hole; a lead-in conductor, one end of which is connected to and supports, the tungsten-halogen lamp, and the other end of which extends through, and is connected to, the eyelet; and an adhesive filling the space between the eyelet and the sides of the hole for the entire thickness of the reflector.
Claim 6
Dependent Claim
101 words
A reflector electric lamp comprising: a curved glass reflector having a predetermined thickness; a sealed tungsten-halogen lamp disposed within the reflector; a metal eyelet extending completely through a hole in the reflector and fastened to the reflector, there being a space between the eyelet and the sides of said hole; a lead-in conductor, one end of which is connected to and supports, the tungsten-halogen lamp, and the other end of which extends through, and is connected to, the eyelet; and an adhesive filling the space between the eyelet and the sides of the hole for the entire thickness of the reflector.
Claim 7
Dependent Claim
108 words
A reflector electric lamp comprising: a curved glass reflector; a sealed tungsten-halogen lamp disposed within the reflector; a metal eyelet having an external end and extending completely through a hole in the reflector and fastened to the reflector; a lead-in conductor, one end of which is connected to, and supports, the tungsten-halogen lamp, and the other end of which extends through, and is connected to, said eyelet; and an external contact lug having a hole therethrough, the external end of the eyelet protruding through said hole in the external contact lug and being flattened over to secure both the external contact lug and the eyelet to the reflector.
Claim 8
Dependent Claim
108 words
A reflector electric lamp comprising: a curved glass reflector; a sealed tungsten-halogen lamp disposed within the reflector; a metal eyelet having an external end and extending completely through a hole in the reflector and fastened to the reflector; a lead-in conductor, one end of which is connected to, and supports, the tungsten-halogen lamp, and the other end of which extends through, and is connected to, said eyelet; and an external contact lug having a hole therethrough, the external end of the eyelet protruding through said hole in the external contact lug and being flattened over to secure both the external contact lug and the eyelet to the reflector.
Claim 9
Dependent Claim
24 words
The lamp of claim 1 wherein the space between the lead-in conductor and the smaller diameter portion of the eyelet is sealed with solder.
