Led light fixture

Abstract

A light fixture includes a housing and an LED light assembly provided on the housing. A visor extends from the housing at least partially around the LED light assembly. A heater element is connected to the visor.

What is claimed is: 
     
         1 . A light fixture comprising:
 a housing;   an LED light assembly provided on the housing;   a visor extending from the housing at least partially around the LED light assembly; and   a heater element connected to the visor.   
     
     
         2 . A light fixture as set forth in  claim 1 , wherein at least a portion of the heater element is screen printed directly onto the visor. 
     
     
         3 . A light fixture as set forth in  claim 1 , wherein the heater element is mounted to an inner surface of the visor. 
     
     
         4 . A light fixture as set forth in  claim 1 , further comprising a solar panel mounted to an outer surface of the visor for powering the heater element. 
     
     
         5 . A light fixture as set forth in  claim 1 , further comprising a solar panel mounted to an outer surface of the visor for powering the LED light assembly. 
     
     
         6 . A light fixture as set forth in  claim 1 , wherein the heater element is a PTC heater element. 
     
     
         7 . A light fixture as set forth in  claim 1 , wherein the heater element is a fixed wattage heater element. 
     
     
         8 . A light fixture as set forth in  claim 1 , wherein the heater element includes a connector tail on which electrical terminals are mounted, the connector tail extending through an interface between the LED light assembly and the housing to an interior space of the housing. 
     
     
         9 . A light fixture as set forth in  claim 1 , wherein the heater element is connected to the visor with adhesive. 
     
     
         10 . A light fixture as set forth in  claim 1 , wherein the heater element is heat staked to the visor. 
     
     
         11 . A light fixture as set forth in  claim 1 , wherein the heater element is overmolded to the visor. 
     
     
         12 . A light fixture as set forth in  claim 1  wherein the heater is welded between the inner surface and an outer surface of the visor. 
     
     
         13 . A light fixture as set forth in  claim 1 , further comprising a temperature sensor for determining when the heater element should be energized. 
     
     
         14 . A light fixture as set forth in  claim 1 , further comprising a humidity sensor for determining when the heater element should be energized. 
     
     
         15 . A light fixture as set forth in  claim 1  wherein the heater resistance is used to determine when the heater should be energized. 
     
     
         16 . A light fixture as set forth in  claim 1 , wherein the housing and the visor are formed as part of a traffic light. 
     
     
         17 . A light fixture as set forth in  claim 1  wherein the heater element is the same color as the inner surface of the visor. 
     
     
         18 . A light fixture as set forth in  claim 1 , further comprising a control module connected to the heater element for controlling the temperature of the heater element. 
     
     
         19 . A light fixture as set forth in  claim 18 , further comprising a solar panel secured to an outer surface of the visor for supplying power to the control module. 
     
     
         20 . A light fixture as set forth in  claim 1 , further comprising a solar panel secured to an outer surface of the visor for recharging a battery in the housing. 
     
     
         21 . A light fixture as set forth in  claim 1 , wherein a timer circuit is used to determine when the heater element should be energized. 
     
     
         22 . A light fixture as set forth in  claim 1 , wherein a battery backup sensor is used to determine when the heater element should be energized. 
     
     
         23 . A light fixture as set forth in  claim 1 , wherein the functionality of the heater element can be monitored and controlled wirelessly. 
     
     
         24 . A light fixture as set forth in  claim 1 , wherein only a single heater element is connected to the visor. 
     
     
         25 . A light fixture as set forth in  claim 1 , further comprising a second heater element connected to the visor.
