    Abstract: An LED bulb comprises a structural shell formed by folding a flat PCB into a three-dimensional polyhedron shape and a fitting for removably coupling the bulb to a light socket. The PCB comprises a plurality of LEDs, at least one LED mounted electronically on a plurality of faces of the polyhedron, and a driver circuit for driving each LED. The perimeter of the PCB is shaped to join adjacent faces. Each LED produces minimal excess heat, which is partially conducted by a metallic heat sink bridge to the PCB and dissipated to the air through the PCB and through a plurality of spaces in the shell.

  • Patent number: 9435504
    Abstract: A lighting assembly that includes an LED source that generates a light cone (solid angle); and a transparent near field lens having a front surface, a collimating surface, and an aspherical groove. The collimating surface collimates the light cone into a beam that reflects off of the front surface toward the aspherical groove, and the aspherical groove directs the beam away from the lens as an exit cone from a virtual focal point, positive virtual focal ring or a negative virtual focal ring. The exit cone may be evenly distributed, substantially forward or substantially rearward from the virtual focal point or virtual focal ring. Parabolic or aparabolic reflectors can be employed with lighting assemblies having a virtual focal point or virtual focal ring, respectively, to reflect the exit cone in a vehicular exterior lighting pattern.

  • Patent number: 9400100
    Abstract: A light emitting diode (LED) module is in thermal communication with front and back heat sinks for dissipation of heat therefrom. The LED module is physically held in place with at least the back heat sink. A mounting ring and locking ring can also be used to hold the LED module in place and in thermal communication with the back heat sink. Key pins and key holes are used to prevent using a high power LED module with a back heat sink having insufficient heat dissipation capabilities required for the high power LED module. The key pins and key holes allow lower heat generating (power) LED modules to be used with higher heat dissipating heat sinks, but higher heat generating (power) LED modules cannot be used with lower heat dissipating heat sinks.
