Abstract

A manufacturing process for storing measured light output internal to an individual LED assembly, and an LED assembly (100) realized by the process. The process utilizes a manufacturing test system to hold an LED light assembly a controlled distance and angle from the spectral output measurement tool. Spectral coordinates, forward voltage, and environmental measurements for the as manufactured assembly are measured for each base color LED. The measurements are recorded to a storage device internal to the LED assembly. Those stored measurements can then be utilized in usage of the LED assembly to provide accurate and precise control of the light output by the LED assembly.

Abstract

A controller for controlling a light emitting diode (LED) light engine. The controller includes a temperature sensor configured to sensor temperature at the LED light engine. A current sensor senses a drive current of the LED light engine. A voltage differential sensor senses a voltage differential across LEDs of the LED light engine. A timer monitors a time of operation of the LED light engine. Further, a control device controls the drive current to the LED light engine based on the sensed temperature, the sensed drive current, the sensed voltage differential, and the monitored time of operation. Further, the control device outputs an indication of intensity degradation of an LED, and if the intensity degradation exceeds a predetermined threshold the control can output an indication of such to a user, so that the user can be apprised that the LED needs to be changed.

Abstract

A light emitting diode (LED) light bulb that includes plural individual elements as sub-assembly elements of the overall light bulb. Different sub- assembly elements of a lens, a LED printed circuit board, a housing also functioning as a heat sink, a lower housing, and other individual sub-assembly components are utilized. The LED printed circuit board sub~assembly containing the LEDs can also be provided relatively close to a base.

Abstract

A reflector device to be utilized with light emitting diodes (LEDs), and particularly with high-flux LEDs. In the reflector structure individual reflector portions surround at least one LED. Light output from each individual LED is reflected by sloping walls of each individual reflector portion and is redirected. As a result, light that may otherwise be lost is redirected to a more useful direction. Each individual reflector portion can have a cross~section of a conic shape, a complicated curve, and can also be oval in shape. A light device can be realized by utilizing such a master reflector with an LED light source.

Abstract

A light device including side emitting status indicators that provide a true indication of whether light is being output in a primary output direction. The light device includes a light source of at least one LED configured to generate light in the primary output direction. The light generated by the at least one LEDs passes through a. lens device, that may also reflect a portion of the light generated from the at least one LED. Collection optics are provided to capture a portion of the generated light and/or the reflected portion of the light generated from the light source, and are configured to output the captured generated and/or reflected light in a direction other than the primary direction, i.e., in a direction for the side emitting status indicators.
