Abstract

A new and innovative, rugged lighting system is provided. The problem of achieving a lighting system that optimizes ruggedness, luminosity, energy and thermal efficiency, versatility, and unbundling of key components is solved. Embodiments of the present invention include a rugged lighting system comprising a housing unit with a body with integrally formed back, sides, and a front with an opening to provide access to the interior of the housing unit; a first lens configured to substantially cover the opening; a first lens bezel configured to removeably attach to the housing unit over the first lens; a second lens configured for placement over the first lens; and a second lens bezel configured to removeably attach to the housing unit over the first lens bezel. Various embodiments further include a light module within the housing unit with a light emitting diode (LED) mounted to an electronics module having a printed circuit board for operating the LED.

Claims

1. A rugged lighting system comprising:

a housing unit with a body with integrally formed back, sides, and a front with an opening to provide access to the interior of the housing unit, the front also having a recessed keyhole portion;

a first lens configured to substantially cover the opening;

a first lens bezel shaped as a key to fit the recessed keyhole portion and configured to removeably attach to the housing unit over the first lens, the first lens bezel having one or more first apertures for directly receiving one or more bolts to removeably attach the first lens bezel and first lens to the housing unit, the first lens bezel having one or more second apertures for indirectly receiving one or more bolts for the purpose of removeably attaching the first lens, first lens bezel, a second lens, a second lens bezel to the housing unit;

a second lens configured for placement over the first lens;

a second lens bezel configured to removeably attach to the housing unit over the first lens bezel, the second lens bezel having one or more first apertures for directly receiving one or more bolts to removeably attach the second lens and second lens bezel to the housing unit;

wherein the first lens bezel is configured to nest between the second lens bezel and the housing unit, the first lens and first lens bezel configured to form a primary seal of the light and electronics modules, and the second lens and second lens bezel configured to form a secondary seal of the light and electronics modules; and

a light module within the housing unit comprising a light emitting diode (LED) mounted to an electronics module with a printed circuit board for operating the LED.

2. The rugged lighting system of claim 1, the light module operable to detect heat and power down to prevent thermal damage to the system.

3. The rugged lighting system of claim 1, further having an external power means with multiple power connections such that power may be alternately applied to connection points to achieve high power and low power modes of operation.

4. The rugged lighting system of claim 1, further comprising a photo eye capable of detecting daylight and night time conditions, the light module further capable of automatically turning off and on based upon settings of the photo eye.

5. The rugged lighting system of claim 1, the first lens bezel having one or more corners substantially wider than a corresponding side for providing additional protection to the housing unit.

6. The rugged lighting system of claim 1, the second lens bezel having one or more corners substantially wider than a corresponding side for providing additional protection to the housing unit.

7. The rugged lighting system of claim 1, the housing unit having one or more corners substantially wider than a corresponding side for providing additional protection to the housing unit.
