A feedback circuit is included from the lighting module to the power supply causing the power supply voltage to be sufficient to provide a constant current voltage at the LED module. A method according to the present invention for generating a constant current voltage to drive a constant current device, comprises providing a drive voltage to a constant current device. The current at the constant current device is sensed a first time, and the drive voltage is increased. The current to the constant current device is sensed a second time. The drive current is held at its increased level if the current did not increase from the first to the second sensing. The increasing of the drive voltage and sensing of the current is repeated of the current did increase between the first and second sensing.
A package for holding a plurality of LED modules interconnected by wire. The package comprises a plurality of cradles each of which is sized to hold a respective one of the interconnected LED modules. Each of the cradles comprises first and second opposing side vertical surfaces partially defining a space for holding its respective one of the LED modules, each of the LED modules arranged in a respective one of the cradles. A plurality of holding tabs is included at least one of which is on one of the first and second opposing side vertical surfaces of each of the cradles and protruding into the module holding space. Each of the tabs is arranged to hold its respective one of the modules in its cradle, wherein the cradles are arranged adjacent to one another with the interconnecting wire running between adjacent cradles.
A method for forming a protective jacket over a connection region includes connecting the leads of an electronic device to conductors such that the connections are in a connection region, placing the connection region in a mold, injecting molten protective material into the mold to cover the connection region, allowing the molten material to cool and harden and removing the connection area from the mold.

LED controller and method using variable drive currents
A system and method is disclosed for illuminating a plurality of emitters such as light emitting diodes (LEDs). The system comprises a plurality of LEDs and a circuit to provide a digital signal. An LED drive circuit is included comprising a first converter for converting the digital signal to one or more analog voltages. The LED drive circuit further comprises a second converter that converts the one or more analog voltages into corresponding one or more drive currents. Each of the drive currents is applied to at least one of the plurality of LEDs to cause the at least one of the plurality of LEDs to emit light. The intensity of emission of the LEDs is related to the level of the applied drive current.
A method for bending a perimeter light and a perimeter light for illuminating curved surfaces. One embodiment of a bending method according to the present invention comprises heating a perimeter light to make it pliable. A radius tool is then provided having a curved surface with a shape and radius for the desired bend in the perimeter light. The heated perimeter light is mounted to the radius tool curved surface. The perimeter light is then cooled and removed from the radius tool. One embodiment of a bent elongated perimeter light according to the present invention comprises an array of light sources and an elongated tube bent to match a curve or shape. The array of light sources is disposed within the tube and the tube transmits and disperses the light from the array to give the appearance that said array of light sources is a continuous light source. The array of light sources is cuttable at intervals to shorten the array while allowing the remaining light sources in the array to emit light. The tube is also cuttable to match the length of the array. A system for mounting perimeter lights to body has straight and curved surfaces comprises a plurality of straight and bent elongated perimeter lights that are mountable in a daisy-chain to the straight and curved surfaces.
