The surface mounted LED package disclosed herein includes an LED having a first surface, a second surface opposite to the first surface, two electrical contacts on the first surface, and a light emitting portion in the second surface; a housing mounted on the LED and having a generally rectangular parallelepipedal shape, a first passageway extending from a first surface of the housing part way through the housing, the first passageway being sized, shaped, and positioned to receive the second sur...

A light emitting apparatus (8) includes one or more light emitting chips (10) that are disposed on a printed circuit board (12) and emit light predominantly in a wavelength range between about 400 nanometers and about 470 nanometers. The printed circuit board includes: (i) an electrically insulating board (14); (ii) electrically conductive printed circuitry (20); and (iii) an electrically insulating solder mask (22) having vias (24) through which the one or more light emitting chips electrically...

Apparatus for collecting light from an LED and transmitting it in a near-uniform column incudes a conical reflector having a roughed up inner surface about the base of the LED for collecting light emitted to the sides of the LED, and a lens specially designed to focus the collected light into a near-collimated beam. The lens has opposite, substantially elliptical surfaces to collect and collimate the rapidly diverging light from the LED and the reflector, and each lens surface includes a flat sp...

A front lighted display for an instrument dial face and pointer, including in combination with such dial face and pointer and according to one embodiment, a plurality of light emitting diodes (LED) positioned around the inner periphery of an LED mounting and directing light rays onto the dial face, a conically shaped reflector positioned to reflect light from the LEDs onto the dial face, a center disc reflector having an LED mounted thereon to enhance illumination of the pointer hub and center a...

An article of jewelry consists of first and second lengths of electrically conductive wire with a light emitting diode connected across a first set of the free ends of the wire lengths. A restraining diode is connected across the lengths of wire in close proximity to but inwardly of the first set of free ends. The restraining diode is electrically connected in opposition to the current flow through the light emitting diode. A linear integrated oscillator circuit and a low voltage power source ar...

An LED flasher circuit is attached to a battery-cell-powered lamp and connected to the battery power source to provide a finding aid for the battery lamp in the dark.

A pair of dice each having twelve flat surfaces and in which opposite surfaces lie in parallel planes is provided. Each die incorporates twelve light emitting diodes for illuminating respectively the 12 surfaces but interconnected with a central battery by way of gravity responsive switches in such a manner that only the topmost surface of the die will be illuminated after the die has been thrown and comes to rest on a flat surface.

The invention relates to an assembly for illuminating objects with light of different wavelengths in microscopes, automatic microscopes and devices for fluorescent microscopy applications. Said assembly comprises LED light sources for illuminating the objects, which are positioned in the illumination beam path of the microscope or device. A receiving element (6; 13) that can be rotated about a rotational axis (5) is provided with respective fixing elements (7) for at least one LED (3; 3.1). The ...

A removable panel-illuminating module is provided wherein the module comprises an array of light-emitting diodes. The module is quickly and easily installed and de-installed from standard panel circuitry connections without having to rotate the planar surface of the module.

A surface mounted LED package according to the invention includes a housing having a generally rectangular parallelepipedal shape. A lens is received in a passageway in the housing and has a radiating surface extending beyond the surface of the housing, a rear light collecting surface, and a cavity to receive an LED. An LED is received in the lens cavity. Conductive spring clips engage the housing and make electrical contact with the LED.
