Abstract
An emergency sign includes a body having a top, two spaced apart sides, and a bottom defining a cavity, a front cover having an inside surface and cut out portions extending through the cover forming indica, a light source disposed within the cavity, and a diffuser coupled to the cover and covering the indicia, the diffuser having cut away portions for permitting light from the light source to reflect off of the inside surface of the front cover. The diffuser may include pigment therein, which pigment is color matched to correspond to the wavelength of the light from the light source. The light source may include an array of LEDs where some of the LEDs are of a diffused type and some of the LEDs are of a unidirectional type.
Claims60
An internally illuminated sign, comprising:
- a body having a top, two spaced apart sides, and a bottom, the top, sides and bottom having inside and outside surfaces, the inside surfaces defining a cavity;
- a front cover having an inside surface, an outside surface, and cut out portions extending through the cover forming indicia, the cover being operatively coupled to the body and substantially closing a front part of the cavity;
- a rear cover operatively coupled to the body opposite the front cover and substantially closing a rear part of the cavity;
- a light source disposed within the cavity;
- and
- a diffuser coupled to the cover and at least partially covering the indicia, the diffuser having cut away portions formed within a perimeter of the diffuser for permitting light from the light source to reflect off of the inside surface of the front cover, the cut away portions being sized and shaped to substantially conform to edges of the cut out portions of the indicia.
An internally illuminated sign, comprising:
- a body having a top, two spaced apart sides, and a bottom, the top, sides and bottom having inside and outside surfaces, the inside surfaces defining a cavity;
- a front cover having an inside surface, an outside surface, and cut out portions extending through the cover forming indica, the cover being operatively coupled to the body and substantially closing a front part of the cavity;
- a rear cover operatively coupled to the body opposite the front cover and substantially closing a rear part of the cavity;
- and
- a light source disposed within the cavity, the light source including an array of LEDs, wherein at least one of the LEDs is a diffused type LED and at least one of the LEDs is a unidirectional type LED.
