Lighting device for accent lighting & methods of use thereof

Abstract

Embodiments of invention are directed to a lighting device for use in accent lighting applications. In one embodiment, the lighting device includes a coherent light source, such as a laser, and a diffractive optical element. The diffractive optical element may be, for example, a holographic optical element. The lighting device may be adapted to retrofit into a pre-existing light fixture. In one application, the lighting device may project a static or movable star field and/or static or movable clouds.

Description

CLAIM OF PRIORITY UNDER 35 U.S.C. §119 [0001]This application claims the benefit of U.S. Provisional Application No. 61 / 112,839 entitled “Interchangeable Modified Light Bulb” filed Nov. 10, 2008.FIELD OF INVENTION[0002]Lighting device for accent lighting applications.BACKGROUND OF INVENTION[0003]Lighting design is both a science and an art. Comprehensive lighting design requires consideration of the amount of functional light provided, the energy consumed, as well as the aesthetic impact supplied by the lighting system. Lighting in such venues as casinos, theatres, nightclubs and concert stages are primarily concerned with enhancing the appearance and emotional impact of the architecture or concert through lighting systems. Therefore, it is important that the sciences of light production and luminaire photometrics are balanced with the artistic application of light as a medium in our built environment. Often, accent lighting for the type of venues described above can be extremely so...

Benefits of technology

[0006]The lighting device may further include: (d) a housing to house the coherent light source, the housing having an opening to allow light emanating from the coherent light source to project therethrough; and (e) a first heatsink positioned about the housing. The first heatsink may define a lumen, the lumen having the housing therein, the first heatsink having a plurality of fins on an outer periphery thereof. The lighting device may further include a threaded base adapted to retrofit into a socket of the light fixture, the threaded based in electrical communication with the coherent light source. The lighting device may further include: (f) a plate to secure the

Problems solved by technology

Often, accent lighting for the type of venues described above can be extremely sophisticated and costly.

Such accent lighting is typically limited to “dimmer” lighting capabilities and/or mo
