Some embodiments of the present utility model are described in detail below with reference to the accompanying drawings. The following embodiments and features of the embodiments may be combined with each other without conflict.

As shown in fig. 1 to 9, according to a first aspect of the present utility model, the present utility model provides an LED lamp bead 100, which includes a light emitting component 20, a packaging adhesive 30 and an LED support 10, wherein the LED support 10 includes an insulating base 11 and a plurality of conductive pins 12, and the plurality of conductive pins 12 are integrally insert-molded with the insulating base 11, so that the conductive pins 12 and the insulating base 11 can form a whole, and the LED lamp bead is simple in production, low in cost, and each conductive pin 12 does not need to be mounted on the insulating base 11, and is not loose or slip, long in service life and high in stability.

Wherein, the encapsulation glue 30 is filled in the reflective cup and covers the light emitting assembly 20, for sealing the light emitting assembly 20 in the reflective cup. Wherein, the packaging glue 30 packaged on the reflecting cup can be packaging glue with high transparency; alternatively, the encapsulation glue 30 encapsulated on the reflector cup may be a combination of transparent glue and fluorescent glue.

The fluorescent glue may be disposed in a partial area of the transparent glue, or the fluorescent glue may also be composed of fluorescent glue with different colors, so as to adjust the equivalent of the light emission of the LED lamp bead 100.

In an alternative embodiment, the other portion of the conductive pins 12 is exposed from the side surface of the insulating base 11 and is located on one side surface of the insulating base 11, so that the LED lamp bead 100 can be mounted on the side surface through the conductive pins 12, so that the light emitting direction of the light emitting component 20 is parallel to the mounting plane of the LED lamp bead 100 and faces the opposite direction of the LED support 10, thus the width of the LED lamp bead 100 can be reduced, and a narrower application scenario can be applied.

Specifically, the axes of the reflective cups on the opposite two end surfaces of the insulating base 11 are perpendicular to the axes of the planes of the conductive pins 12, namely, when the LED lamp beads 100 are mounted through the conductive pins 12, the light emitting directions of the light emitting assemblies 20 in the reflective cups are parallel to the mounting planes of the LED lamp beads 100, and the reflective cups are arranged on the opposite two end surfaces of the insulating base 11, so that when the LED lamp beads 100 are mounted on a table surface, the two sides of the LED lamp beads 100 can emit light at the same time, and the light emitting directions of the two sides of the LED lamp beads 100 are opposite and parallel to the mounting planes of the LED lamp beads 100.

In this embodiment, the LED lamp bead 100 is mounted on a side surface through the conductive pins 12 on the side surface, so that the axes of two opposite end surfaces of the insulating base 11 can be parallel to the mounting plane of the LED lamp bead 100, thereby realizing the double-sided light emitting effect of the LED lamp bead 100, and thus, the conductive pins 12 are not required to be arranged on other side surfaces of the LED lamp bead 100, for example, the conductive pins 12 are not required to be arranged in the length direction of the side surface of the LED lamp bead 100, and any conductive pins 12 are not required to be arranged in the width direction of the side surface of the LED lamp bead 100, so that the width of the side surface of the LED lamp bead 100 can be reduced, and the LED lamp bead 100 can be suitable for a relatively narrow application scene. In addition, the reflective cup is arranged in two directions perpendicular to the side surface, so that the orientation of the reflective cup can be parallel to the mounting plane when the LED lamp beads 100 are mounted on the side surface, and double-side light emission of the LED lamp beads 100 is realized.
