Abstract: A lighting device has a power interface and a control circuit in communication with a program and the LEDs to simulate a flame. The program determines a first group of LED control integers to simulate a perpetual middle with a perpetual middle center and a perpetual middle range within which one or more of the LEDs are to be at least partially actuated. At least one LED is actuated based on the first group of LED control integers. A first target for simulating movement of the perpetual middle center toward the first target and a first acceleration value is defined. The program determines a second group of LED control integers based on the first target and the first acceleration value such that the perpetual middle center becomes closer to the first target. One or more of the LEDs is actuated based on the second group of LED control integers.

Abstract: A system and method for lighting effects, including simulating a flame, a spark, or a perpetual middle, is disclosed. One or multiple three dimensional substrates include one or multiple arrays of light sources, such as LED, mounted on or into them. A control circuit can actuate the light sources in a manner to simulate different light effects including rising and contracting sparks within a flame and a center of the flame whose properties adjust to sparks traveling through and above it. The control circuit can further actuate the light sources to simulate a real flame effect by combing a simulated spark and a simulated perpetual middle. This system can include a light engine in a light fixture such as an architectural fixture.

Abstract: A road flare including a two-sided panel, each side containing a grid of light-emitting diodes (LEDs). In a preferred embodiment one side would include typical white or standard colored LEDs and the other side would include red or other color LED. Each panel has several modes of lighting, which is selectable via a power switch or other switch. The different modes include solid lights, blinking lights, off, or a combination thereof. For example, the red side of the panel may be set to blinking or flashing, while the white side of the panel could be constantly lit. This creates a flashing hazard strobe facing away from a vehicle to warn oncoming vehicles, and a solid white light source aimed towards the vehicle to assist with repairs or other tasks.
