An apparatus for improving the performance of flashlights includes a substantially cylindrical housing () having a first end () and a second end (). A battery cap () is operatively connected to the first end of the housing and functions to secure a series of batteries in place. A series () of light emitting diodes (LED) () are mounted within the flashlight housing at the end opposite the battery cap. The series of LEDs form an LED array which operates as the light source for the flashlight. A substantially cone-shaped optical assembly () extends outward from the second end of the housing and operates to focus and disperse the LED beam emitted by the LED array. The flashlight further includes an adjustable switch () disposed on the exterior of the housing. The switch is coupled to a variable resistor () which permits control over the light level and/or battery life. An electronic current regulator (), enclosed by the housing, allows the LED beam to remain at a constant and desired light level, thereby increasing the efficiency of the battery life. A dynamic pulse control system () is coupled to the switch which takes advantage of the human eye perceiving the pulsed beam to be continuous. The pulse control also increases the peak current through the LED source.

Flashlight with light emitting diode source

An apparatus (A) for improving the performance of undercabinet lighting includes a housing ( ) that receives a plurality of light emitting diodes (LEDs) ( ). The LEDs serve as the light source and an optical assembly focuses and disperses the LED output to a desired light contour. The undercabinet lighting assembly further includes a switch ( ) formed from a variable resistor adapted to control the level of optical output. The switch is adapted to turn on and off any select number of LEDs. A battery pack ( ) having a battery source is enclosed by the housing for providing back up power and emergency lighting. In a preferred embodiment, the battery source automatically provides power to the undercabinet lighting assembly upon primary power failure.

Undercabinet lighting with light emitting diode source

A series of light emitting diodes (LEDs) are mounted within a housing ( ) and operate as the light source for a nightlight. One LED ( ) is positioned at each of the four corners of the housing forming an array of LEDs which generates an LED emitted light. The LEDs are all interconnected through printed wiring ( ) mounted within the housing. Power is provided to each of the LED's through the printed wiring which is coupled to a power source. The power source can be a battery assembly ( ), an electrical outlet or an energy storage device. An adjustable switch ( ) is disposed on an exterior surface of the wall plate and is coupled to a variable resistor enclosed by the housing. The switch permits control over the optical output.
