1. A lighting system for emitting light in multiple directions comprising:
- at least one light emitting device (LED) configured to generate light in a first direction to illuminate a first area proximate to the lighting system; and
a housing configured to receive the at least one LED, the housing being configured to reflect a portion of the generated light so as to allow a remaining portion of the generated light to pass through the housing in a second direction, different from the first direction, and illuminate a second area proximate to the lighting system, wherein the first and second areas proximate to the lighting system are outside the housing,wherein the first direction is below the housing and the second direction is above the housing.

Abstract
Lighting systems for emitting light in multiple directions including one or more light emitting devices (LEDs) and a housing configured to receive the one or more LEDs are provided. The one or more LEDs are configured to generate light in a first direction to illuminate a first area proximate to the lighting system. The housing is configured to reflect a portion of the generated light so as to allow a remaining portion of the generated light to pass through the housing in a second direction, different from the first direction, and illuminate a second area proximate to the lighting system. Related methods are also provided herein.

6. A lighting system for emitting light in multiple directions comprising:
-
at least one light emitting device (LED) configured to generate light in a first direction to illuminate a first area proximate to the lighting system; and a housing configured to receive the least one LED, the housing being configured to reflect a portion of the generated light so as to allow a remaining portion of the generated light to pass through the housing in a second direction, different from the first direction, and illuminate a second area proximate to the lighting system wherein the first and second areas proximate to the lighting system are outside the housing, wherein from about 75 to about 90 percent of a total amount of light generated by the at least one LED illuminates the first area and wherein from about 10 to about 25 percent of the total amount of light generated by the at least one LED illuminates the second area. - View Dependent Claims (7)

8. A lighting system for emitting light in multiple directions comprising:
-
at least one light emitting device (LED) configured to generate light in a first direction to illuminate a first area proximate to the lighting system; and a housing configured to receive the at least one LED, the housing being configured to reflect a portion of the generated light so as to allow a remaining portion of the generated light to pass through the housing in a second direction, different from the first direction, and illuminate a second area proximate to the lighting system, wherein the first and second areas proximate to the lighting system are outside the housing, wherein the housing defines a cavity, wherein the at least one LED is positioned to emit light into the cavity towards the housing, wherein the housing is configured to reflect at least a portion of the light emitted into the cavity to illuminate the first area proximate to the lighting system and wherein the housing comprises a semi-reflective housing including silver, chrome, metal alloys and/or any semi-reflective material.

9. A method of emitting light in multiple directions in lighting systems including light emitting devices (LEDs) comprising:
-
generating light in a first direction to illuminate a first area proximate to the lighting system using at least one LED; and reflecting a portion of the generated light in the first direction using a semi-reflective housing so as to allow a remaining portion of the generated light to pass through the housing in a second direction, different from the first direction, and illuminate a second area proximate to the lighting system, wherein the first and second areas proximate to the lighting system are outside the semi-reflective housing. - View Dependent Claims (10, 11, 12, 13)
