Abstract
An LED based lamp comprises: an enclosure with an opening that comprises a light emission plane through which light is emitted from the lamp; a plurality of LEDs located along at least one wall of the enclosure and operable to generate light of a first wavelength range, wherein the LEDs are configured such that in operation their emission axis is oriented within a plane that is substantially parallel with or directed away from the light emission plane; and a first light reflective surface located on the base of the enclosure and configured such that in operation light is reflected through the light emission plane. A light emitting sign comprises the lamp of the invention with a light transmissive display surface overlying the light emission plane.
Claims26
An apparatus, comprising:
- an enclosure with an opening that comprises a light emission plane through which light is emitted from the lamp;
- a plurality of light emitting diodes located along at least one wall of the enclosure and operable to generate first light of a first wavelength range, wherein
- the plurality of light emitting diodes are configured such that in operation their emission axis is oriented within a plane that is substantially parallel with or directed away from the light emission plane;
- a first light reflective surface located on the base of the enclosure having a convex shape and configured such that the first light is reflected off the first light reflective surface to disperse the first light at a plurality of different angles relative to the light emission plane;
- and
- one or more phosphor elements to absorb at least a portion of the first light emitted from the plurality of light emitting diodes to re-emit second light having a second wavelength range.
