Definitions

  • the present invention relates to lighting devices, and more particularly, to illumination devices adapted to provide high intensity lighting.
  • a known problem with using typical prior art lights in high intensity applications is that the lights consume large quantities of power and generate excessive heat in comparison to other lighting devices. These applications thereby suffer not only from higher operating costs and limited portability due to the devices large power consumption, but also can become susceptible to premature failure due to the prolonged exposure to excessive heat.

  • the diameters of these circular cross-sections 28 and 30 are sized to securely engage the linear light source 4.

Abstract

L'invention concerne un dispositif d'éclairage haute intensité (2). Ce dispositif d'éclairage possède une source de lumière linéaire (4), un élément réfléchissant (6) et une zone translucide (14). La source de lumière linéaire et l'élément réfléchissant se trouvent normalement sur le même axe. L'élément réfléchissant, qui peut avoir diverses formes, fait en sorte que la lumière, qui devrait normalement être absorbée ou se propager à l'intérieur du boîtier (8), converge dans la zone translucide. La zone translucide possède un axe longitudinal qui coïncide avec l'axe commun des rayons lumineux dirigés dans une zone d'intérêt. En cas de besoin, on peut aussi utiliser une lentille (44) pour collimater les rayons lumineux, par exemple, une lentille cylindrique ou un ou plusieurs prismes (50).
