Medical Headlamp Optical Arrangement
First Claim
1. A lamp having a front surface from which light is emitted, comprising:
- (a) a high efficiency light source assembly producing a beam having a 3 dB beamwidth of greater than 100°
, said assembly having;
(i) a substrate;
(ii) a high efficiency light source supported by said substrate; and
(iii) said high efficiency light source being contained in a lens in the form of a dome, positioned in front of and about said high efficiency light source and being supported by and joined to said substrate;
(b) an optical assembly positioned to receive light from said high efficiency light source assembly and produce a lamp light beam emitted from said front surface of said lamp;
(c) a housing supporting said light source and said optical assembly and an electrical conductor connected to said light source, for supplying electricity to said light source; and
(d) an annular light block, defining an annulus and placed about said lens, so that said lens protrudes through said annulus, thereby creating a sharp boundary for said output light beam.

Abstract
A lamp having a front surface from which light is emitted and that includes a high efficiency light source assembly producing a beam having a 3 dB beamwidth of greater than 100 AE, and which includes a substrate, a high efficiency light source supported by the substrate; and a dome-lens that contains the high efficiency light source. Also, an optical assembly is positioned to receive light from the light emitting diode assembly and to produce a headlamp light beam emitted from the front surface of the lamp. Further, an annular light block defines an annulus and is placed about the lens, so that the lens protrudes through the annulus, thereby creating a sharp boundary for the output light beam.

15. A lamp having a front surface from which a beam of light is emitted, comprising:
-
a. a housing; b. a high efficiency light source assembly, including a high efficiency light source covered by a lens, supported within said housing; c. an optical assembly, supported by said housing and having a front surface that is coincident with said front surface of said lamp and positioned to accept light from said high efficiency light source assembly and to emit said light from said front surface, and having a rear surface that defines a concavity; and d. wherein said lens protrudes into said concavity. - View Dependent Claims (16, 17, 18, 19)
