Head lamp

Abstract

A head lamp assembly wearable by a user or attachable to an object comprising a substrate, a first light source, a second light source, and a sensor. The sensor can turn the first and second light sources ON when light striking the sensor falls below a predetermined intensity level. The sensor can turn the first and second light sources OFF when light striking the sensor exceeds a predetermined intensity level. An override switch can allow user to keep the light sources either completely illuminated or obfuscated, irrespective of the sensor.

What is claimed is: 
     
       1. An assembly comprising:
 a substrate wearable by a user or attachable to an object; 
 a sensor power source attached to the substrate; 
 a sensor attached to the substrate and electrically connected to the sensor power source; 
 a first light power source attached to the substrate; 
 a first light source attached to the substrate and electrically connected to the sensor and to the first light power source; 
 a second light power source attached to the substrate; and 
 a second light source attached to the substrate and electrically connected to the sensor and to the second light power source; wherein 
 the sensor being operable to turn ON the first light source and the second light source when light striking the sensor falls below a first predetermined intensity level whether or not the assembly is in motion, the sensor being further operable to turn OFF the first light source and the second light source when light striking the sensor exceeds a second predetermined intensity level; 
 wherein, the first predetermined intensity level and the second predetermined intensity level is the same or different, and the sensor power source, the first light power source, and the second light power source are the same or different. 
 
     
     
       2. The assembly of  claim 1  further comprising:
 a main user switch for turning the assembly ON and OFF; 
 a first user switch being accessible for manual use for turning ON the first light source when the first light source is turned OFF by the sensor, the first user switch being further operable to turn OFF the first light source when the first light source is turned ON by the sensor; and 
 a second user switch being accessible for manual use for turning ON the second light source when the second light source is turned OFF by the sensor, the second user switch being further operable to turn OFF the second light source when the second light source is turned ON by the sensor, the second user switch being further operable to control the second light source to operate in a continuous light mode or in a blinking light mode when the second light source is turned ON by the sensor. 
 
     
     
       3. The assembly of  claim 1 , wherein the first light source comprises at least one white light LED coupled to the substrate. 
     
     
       4. The assembly of  claim 1 , wherein the second light source comprises a plurality of amber light LEDs coupled to the substrate. 
     
     
       5. The assembly of  claim 2 , wherein the second user switch is further operable to control a blinking frequency of the second light source when the second light source is operating in the blinking light mode. 
     
     
       6. The assembly of  claim 2 , wherein the first user switch is further operable to increase and decrease an intensity of light generated by the first light source when the first light source is turned ON. 
     
     
       7. The assembly of  claim 2 , wherein the second user switch is further operable to increase and decrease an intensity of light generated by the second light source when the second light source is turned ON. 
     
     
       8. The assembly of  claim 1 , wherein both the first predetermined intensity level and the second predetermined intensity level are adjustable. 
     
     
       9. The assembly of  claim 1  further comprising an audible warning system coupled to the substrate and electrically connected to at least one of the power sources. 
     
     
       10. The assembly of  claim 1  further comprising a light sync attached to the substrate and electrically connected to at least one of the power sources and the second light source. 
     
     
       11. The assembly of  claim 1  further comprising a flash memory, a reflector, and a retention strap.
