Abstract
A direct lighting system and method is provided that includes a plurality of light-emitting diodes (LEDs) secured within a light fixture. The lighting system further includes a diffusive transmissive element adapted to transmit light from the LEDs therethrough and provide diffused light to an area requiring illumination.
Claims19
A method of lighting with light emitting diodes (LEDs) oriented to directly radiate light energy onto a surface to be illuminated without bright spots being observable therefrom, the method comprising:
- providing a light fixture having an illumination opening oppositely disposed from a mounting surface for passing light energy therethrough;
- removably engaging an LED assembly to the mounting surface within the light fixture, the LED assembly having a plurality of LEDs disposed thereon and oriented to radiate light energy directly through the illumination opening;
- coupling the LED assembly to a power source;
- providing a lens having select diffusivity and transmissivity properties such that light energy from the LEDs transmitted therethrough is sufficiently diffused to optically mask the LED light energy source such that bright spots are not observable therefrom;
- securing the lens across the illumination opening of the light fixture, the lens being disposed between the LED assembly and the surface to be illuminated;
- and
- wherein when power is provided to the LEDs, light radiates from the LEDs directly through the lens in a manner diffusing and optically masking the LED light energy.
A system for providing lighting using light emitting diodes (LEDs) oriented to directly radiate light energy onto a surface to be illuminated without bright spots being observable therefrom, the system comprising:
- a light fixture having an illumination opening oppositely disposed from a generally flat mounting surface;
- a cradle mateably engaging the mounting surface of the light fixture;
- an LED assembly having a plurality of LEDs disposed thereon, the LED assembly being disposed between the mounting surface and the cradle;
- a translucent lens disposed across the opening, the lens having select diffusivity and transmissivity properties such that light energy from the LEDs transmitted therethrough is sufficiently diffused to optically mask the LED light energy source such that bright spots are not observable therefrom;
- and
- wherein when power is provided to the LEDs, light radiates from the LEDs directly through the lens in a manner diffusing and optically masking the LED light energy.
A method of lighting with light emitting diodes (LEDs) oriented to directly radiate light energy onto a surface to be illuminated without bright spots being observable therefrom, the method comprising:
- mounting a plurality of light fixture assemblies in an area to be illuminated, each light fixture comprising:
- an illumination opening oppositely disposed from a mounting surface for passing light energy therethrough;
- an LED assembly removably secured to the mounting surface, the LED assembly having a plurality of LEDs disposed thereon and oriented to radiate light energy directly through the illumination opening;
- and
- a lens removably secured across the illumination opening, the lens having select diffusivity and transmissivity properties such that light energy from the LEDs transmitted therethrough is sufficiently diffused to optically mask the LED light energy source such that bright spots are not observable therefrom;
- and
- providing each light fixture with power, wherein when power is provided to the LEDs, light radiates from the LEDs directly through the lens in a manner diffusing and optically masking the LED light energy.
