Embedded type lamp bead

Abstract

The invention discloses an embedded type lamp bead which comprises a diode wafer (1), a lens (2), a gold wire, a pin (5), packaging glue, a heat sink (7) and a base (4), wherein the heat sink (7), the pin (5) and the lens (2) are assembled together through the base (4), the diode wafer (1) is arranged on the heat sink (7), the gold wire is connected with the diode wafer (1) and the pin (5), and the packaging glue is filled between the diode wafer (1) and the lens (2). The embedded type lamp bead is characterized in that the pin (5) comprises an outer pin (3) and a lead sheet (8), the ring side of the base (4) is provided with a groove and a through hole which are adapted to the outer pin (5) of the pin, and the pin (5) is penetrated in the ring side of the base (4) and is used for wrapping the base and extends to an inner cavity of the base (4) through the lead sheet (8). The embedded type lamp bead adopting the structure has a novel structure, and can adapt to installation demands of a pore plate type base.

Description

[0001] technical field [0002] The invention relates to the field of power light emitting diodes, in particular to a mosaic lamp bead. [0003] Background technique [0004] LED light source has many advantages such as long service life, short start-up time, remarkable energy-saving effect, no ultraviolet radiation, no mercury pollution, and high safety in use.

[0004] LED light source has many advantages such as long service life, short start-up time, remarkable energy-saving effect, no ultraviolet radiation, no mercury pollution, and high safety in use. It is gradually becoming the mainstream of lighting source. However, due to the unique luminous characteristics of LED, Many new requirements have been put forward for LED lighting applications, such as single light color, small light output angle, large heat generation, one-way conduction, etc., all of which need to be adapted in specific lighting solutions, involving from chip structure to chip packaging , from light source design to all levels of lamp structure, the packaging structure of existing LED lamp beads includes diode chips, lenses, gold wires, pins, packaging glue, heat sinks, bases and other components, and each component is assembled on the base through the base At the same time, most of the pins are in the shape of long strips, extending from the inner cavity of the base to the outside of the base, which can facilitate the welding between the lamp beads and the aluminum substrate. , a single pin form can no longer meet the application needs
