HP Introduces High-Brightness Chip-Type Surface-Mount LEDs With Integrated Lenses; LEDs are Ideal for Illuminated Switches and for Coupling to Light Pipes

Business Wire, Jan 25, 1999

PALO ALTO, Calif.--(BUSINESS WIRE)--Jan. 25, 1999-- Hewlett-Packard Company today introduced a series of surface-mount chip-type light-emitting diodes equipped with integrated lenses.

These lenses, which concentrate the emitted light into a typical 70 degree viewing angle, produce double the on-axis light intensity of non-lensed surface-mount chip LEDs using the same active die. This makes these LEDs particularly suitable for illuminating buttons and switches on panels, and for transferring the maximum amount of light to optical light pipes used to illuminate panel legends.

These chip-type LEDs are an excellent choice for use in automotive interiors, such as for backlighting legends on radios and other dash-mounted devices. They are equally suitable as status indicators on the panels of computers; in data-communications equipment, such as hubs, routers, switching equipment and

modems; in office-automation equipment, such as printers, FAX machines and copiers; and in industrial equipment of many different types.

These surface-mount LEDs are designed for today's high-speed automated manufacturing technology. The 3.0mm by 1.5mm package closely matches an industry-standard size for many chip capacitors, making it compatible with available automated pick-and-place equipment. The package also is compatible with infrared and convective reflow soldering processes used in automated assembly.
