It will be understood that the three first light emitting elements 3 can emit three colors of red, blue and green (i.e., three primary colors of light), and the three primary colors are controlled by the driving ICs outside the carrier 1 to be mixed according to different proportions and intensity, so that various color changes can be generated, and the light emitting effect of the product is enriched. Of course, the three first light emitting members 3 may emit the same color (capable of increasing the light emitting brightness of the product) at the same time, or two of the first light emitting members 3 emit the same color (capable of increasing the light emitting brightness of the product), and the remaining one first light emitting member 3 emits another color.

Specifically, the carrier 1 is arranged in a ring shape, and when no component is arranged inside the carrier 1, the channel defined by the peripheral wall of the ring-shaped carrier 1 is the light-emitting channel 11.

It can be understood that, since the sides of the pads near the first light-emitting groove 111 are located on the same horizontal plane, when the wire runs between the pads, the two ends of the wire will not have a height difference, which facilitates the wire to be arranged between the two pads in a shorter length, and meanwhile, since the sides of the pads are located at the same height, the peripheral wall of the wire will not be scratched with the edges of the sides of the pads, which is beneficial to the stable use of the wire.

In addition, since the bonding pads have no level difference in the first light-emitting groove 111, each bonding pad does not affect the light to irradiate from the bottom of the first light-emitting groove 111 to the notch of the first light-emitting groove 111, thereby ensuring the use reliability of the product.

Similarly, three positive electrode pads and three negative electrode pads are each disposed flush near the side of the second light-emitting slot 112. The beneficial effects of such an arrangement are referred to above and will not be described in detail herein.

The insulating support 5 can support the welding disc, prevents that the welding disc from rocking and influencing the normal use of product. Meanwhile, the insulating support 5 can prevent the first light-emitting groove 111 from being communicated with the second light-emitting groove 112, prevent light from being refracted from the first light-emitting groove 111 to the second light-emitting groove 112 or from being refracted from the second light-emitting groove 112 to the first light-emitting groove 111, and ensure the light-emitting effect of the product.

The three positive electrode pads and the three negative electrode pads are each provided with a pin 27, and each pin 27 is provided through the carrier 1 so as to be exposed to the carrier 1. The connection between the external circuit and the pads through the pins 27 has an advantage of higher convenience, however, in other embodiments, the connection between the external circuit and the pads may be realized by wiring in the first light emitting slot 111 or the second light emitting slot 112.

All pins 27 are exposed on the same side of the carrier 1. The arrangement is convenient for users to connect the lines on the same side of the carrier 1, and is convenient for the users to observe and operate.

The three positive electrode pads include a first positive electrode pad 21, a second positive electrode pad 23, and a third positive electrode pad 25, and the three negative electrode pads include a first negative electrode pad 22, a second negative electrode pad 24, and a third negative electrode pad 26; the first positive electrode pad 21, the second positive electrode pad 23, the third positive electrode pad 25, the first negative electrode pad 22, the second negative electrode pad 24 and the third negative electrode pad 26 are arranged in parallel, the first positive electrode pad 21 and the first negative electrode pad 22 are adjacently arranged, the second positive electrode pad 23 and the second negative electrode pad 24 are arranged on one side of the first positive electrode pad 21, which is away from the first negative electrode pad 22, and the third positive electrode pad 25 and the third negative electrode pad 26 are arranged on one side of the first negative electrode pad 22, which is away from the second positive electrode pad 23; wherein,

The connection parts of the pins 27 and the corresponding bonding pads are bent and arranged so that the pins 27 extend in the length direction (the first direction shown in fig. 1) of the carrier 1;

The same extending direction of the two pins 27 means: both pins 27 extend towards the same end close to the carrier 1.

And the extending directions of the two pins 27 are opposite to each other: the two pins 27 extend towards opposite ends of the carrier 1, respectively.

It will be appreciated that, due to the opposite bending directions of the remaining pins 27, the risk of a tin-connected short circuit is smaller during soldering, while, due to the pins 27 of the first positive electrode pad 21 and the pins 27 of the first negative electrode pad 22 both extending towards the same end close to the carrier 1, the risk of a short circuit of these two pins 27 is greater, which is advantageous for avoiding the short circuit by increasing the spacing between these two pins 27.

In addition, the bending part of each pin 27 is provided with a groove body (not shown), and the groove body is arranged to avoid the space required by bending the corresponding pin 27, so that the pin 27 is prevented from being bent in place and extruded and deformed in the processing process.

The first light-emitting groove 111 and the second light-emitting groove 112 are filled with packaging glue (not shown), and the packaging glue seals the components in the first light-emitting groove 111, so that the problems of electric leakage, short circuit and the like are avoided. And the glue can effectively improve the insulation performance and the waterproof performance of the lamp beads and increase the use safety.

In addition, the heat dissipation performance of the first light emitting part 3 and the second light emitting part 4 can be effectively improved by the glue, the service life is prolonged, and when the temperature in the first light emitting groove 111 and the second light emitting groove 112 is reduced, the light emitting efficiency of the first light emitting part 3 and the second light emitting part 4 can be improved. Meanwhile, the glue has the advantages of high refractive index, high light transmittance and the like, and the luminous flux of the first luminous element 3 and the second luminous element 4 can be increased.
