Definitions

  • the light output of a plurality of LED light sources, arranged in individual reflector modules and focused toward a target can be transmitted through a refractor lens positioned at a front of a lamp and operable to create a light pattern and color temperature on the target.
  • Operable lenses may provide converging and/or mixing of the output from the individual light sources.
  • Certain operable such refractor lenses are multifaceted. Functional lenses may range from simple translucent coverings having no significant effect on transmitted light, to complexly arranged members operable significantly to effect a propagation direction, or physical quality, of transmitted light.
  • a plurality of individual lenses may be concatenated to form a single lamp lens. Lenses may be clear, or may modify a color in the transmitted light.
  • Lens 144 may be arranged to disperse, focus, collimate. color, or otherwise modify a characteristic of light 120 passing therethrough.
  • lem 144 - H - may be configured as a protective shield for a module 108, or lamp 100.
  • a collimating lens may be disposed in the space 146 located between LED 1 18 and a distal end 148 of module 108. Desirably, such collimating lens is placed in proximity to the discharge opening of the parabolic reflector 122 to reduce a length of the light module 108.
  • modules 108 are about 6.4 cm (2- 1/2 inches) in length, and approximate the size in a thickness direction of the lamp 100.

Abstract

L'invention porte sur un ensemble de lampe apte à projeter un éclairage sans ombre sur une zone. De façon typique, un ensemble de lampe comprend une pluralité de modules de lumière qui sont disposés selon une relation espacée sur une zone. L'ensemble de lampe peut être agencé pour focaliser la lumière de la lampe sur une zone centrale d'éclairage de haute intensité, l'intensité d'éclairage à l'extérieur de la zone centrale étant réduite de manière significative.
