IR REFLECTING GRATING FOR HALOGEN LAMPS |
摘要 |
A lamp, such as a halogen lamp, includes a bulb which is sealed to define an interior chamber. An emitter, such as a filament, is disposed within the interior chamber which, during operation of the lamp, emits radiation in the visible and infrared regions of the spectrum. An optical grating, generally spaced from the emitter, is positioned to intercept radiation from the emitter. The optical grating reflects infrared radiation and transmits visible radiation therethrough. In this way, the output of the lamp in the visible range can be increased as compared with an otherwise identical lamp formed without the grating. |
