Description

Technical Field

[0001] This utility model relates to the field of lighting fixtures, and in particular to a novel non-polar LED lamp bead. Background Technology

[0002] Existing non-polar LED beads have an interface at each end, with a forward line and a reverse line inside. The forward and reverse lines are connected in parallel and then connected to the two interfaces at their respective ends. The forward and reverse lines contain unidirectional diodes, so no matter how they are installed, at least one of the forward and reverse lines will light up, thus achieving the design goal of non-polarity.

[0003] In practical use, when multiple non-polar LED beads are connected in series, a high forward voltage may pass through a non-emitting chip in the reverse direction at one of the middle beads, causing reverse breakdown. Therefore, a new type of non-polar LED bead is needed that can overcome the technical problem of reverse breakdown when multiple non-polar LED beads are connected in series in the existing technology and can be used with multi-color LED beads. Utility Model Content

[0004] The main objective of this invention is to provide a novel non-polar LED bead that can overcome the technical problem of reverse breakdown when multiple non-polar LED beads are connected in series in the prior art and is applicable to multi-color LED beads.

[0005] This utility model proposes a novel non-polar LED lamp bead, including a lamp bead body;

[0006] The lamp bead body is provided with at least two light source groups, which are not connected to each other. The lamp bead body has pins on both sides, which are the same number as the light source groups, and the pins on both sides corresponding to the light source groups are connected to the light source groups.

[0007] Preferably, the pins on the same side of adjacent light source groups have opposite polarities.

[0008] Preferably, the light source group includes at least one light source and a unidirectional diode.

[0009] The beneficial effects of this novel non-polar LED lamp bead are as follows:

[0010] 1. By adopting a multi-pin design, multiple independent circuits are connected in the series circuit of multiple monochrome new non-polar IED lamp beads. When one group is powered by a relatively high voltage, the others will not be reverse-broken down due to the conductors connecting the pins of traditional non-polar IED lamp beads in the middle of the two series circuits, thereby improving the durability of the product.

[0011] 2. The multi-color LED circuit is designed according to multiple single-color circuits, which also avoids the risk of reverse breakdown, thus overcoming the problems existing in the prior art.

[0012] 3. By adopting a multi-pin design, in actual use, only one or both light source groups can be used, thus meeting the requirements of more usage scenarios. Attached Figure Description

[0018] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0019] Reference Figures 1 to 3 An embodiment of the novel non-polar LED lamp bead of this utility model is proposed:

[0020] A novel nonpolar LED lamp bead, comprising a lamp bead body 1.

[0021] Monochrome LED reference Figure 1 The lamp body 1 contains two light source groups 2, which are not connected to each other. The lamp body 1 has pins 3 on both sides, with the same number of pins as the light source groups 2. The pins on both sides corresponding to the light source groups 2 are connected to the light source groups 2. The pins 3 on the same side of adjacent light source groups 2 have opposite polarities.

[0022] The light source group 2 includes multiple light sources and unidirectional diodes. The light sources can be connected in series or in parallel, and after being connected, they are connected to the diodes in series.

[0023] Multicolor LED reference Figure 2The two upper light source groups 2 are of the same color, and the two lower light source groups 2 are of the same color. The light source groups 2 of different colors are separated by a partition, thus ensuring the luminous effect of the different colored light source groups 2. The specific usage is the same as for monochrome.

[0024] Reference Figure 3 As shown in the usage diagram, in the series circuit of multiple monochrome novel non-polar IED lamp beads designed with this patent, the light source groups 2 corresponding to different lamp bead bodies 1 are connected. This ensures that when one group has a relatively high voltage power supply, the others will not be reverse-broken down due to the conductor connecting the pins of the traditional non-polar IED lamp beads in the middle of the two series circuits, thus improving the durability of the product.

[0025] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the contents of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
