Description

Technical Field

[0001] The utility model relates to the field of lamps, and particularly to an equal-brightness light strip. Background Art

[0002] The existing light-emitting light strip mainly consists of a plurality of light-emitting lamp bead groups. Each light-emitting lamp bead group may include one or more light-emitting lamp beads. Some light-emitting lamp bead groups may also include a control chip, and the light-emitting lamp beads in the light-emitting lamp bead group are controlled by the light-emitting chip. The plurality of light-emitting lamp bead groups are generally connected in parallel, and the light-emitting lamp beads in the light-emitting lamp bead group are generally connected in series, and some are connected in a series-parallel manner.

[0003] For the light-emitting lamp bead groups connected in parallel, theoretically, the voltage of each light-emitting lamp bead group is equal. However, in the usage scenario of the light strip, since a single light strip is too long or the spliced light strip is too long and the light strip generally adopts a design of single-end electrical connection or double-end electrical connection, the line resistance of the light-emitting lamp bead group farther from the input power supply in the light strip gradually increases, resulting in the dimmer brightness of the farther light-emitting lamp bead group, making the brightness between different light-emitting lamp bead groups inconsistent and affecting the user experience.

[0004] In the existing design, in order to solve the problem of inconsistent brightness, the maximum length or the maximum number of lamp beads of a single light strip is often set. After exceeding this maximum length, the subsequent light strip cannot be electrically connected to the previous one, and the subsequent light strip needs to be re-connected to the power circuit. This makes the circuit design and circuit control more complex for some longer light strips. Moreover, such usage scenarios are very common in the daily use of the light strip, so it is an urgent problem to be solved. Summary of the Utility Model

[0005] The main purpose of the utility model is to provide an equal-brightness light strip, which makes the line resistance between the single-end electrically connected light-emitting lamp bead groups consistent by additionally providing an independent circuit on the light strip, so that the light-emitting effects between the light-emitting lamp bead groups are consistent, and the circuit is simple and the installation is convenient.

[0006] The utility model provides an equal-brightness light strip, which includes at least one light strip body, a plurality of light-emitting lamp bead groups arranged on the light strip body, a positive electrode line, a negative electrode line and an independent line;

[0007] The positive electrode line and the negative electrode line are arranged on the light strip body. Both ends of the light-emitting lamp bead group are respectively connected to the positive electrode line and the negative electrode line, and a positive electrode interface and a negative electrode interface are respectively arranged at both ends of the positive electrode line and the negative electrode line;

[0008] The end of the independent line is connected to the positive interface or the negative interface at the end of the positive line or the negative line, so that the sum of the line lengths from each light-emitting bead group to the input line and the output line of the external line is equal, so that the line resistance between the light-emitting bead groups is consistent and the light-emitting effect is consistent.

[0009] Preferably, the independent line is an internal line. The internal line enters from the front end of the light strip with equal brightness and winds around to the rear end of the light strip with equal brightness and is connected to the positive interface or the negative interface at the rear side of the last light-emitting strip body.

[0010] Preferably, the independent line is arranged on the light-emitting strip body, and independent line interfaces are respectively arranged at both ends of the independent line. The independent line interface at the end of the independent line is connected to the positive interface or the negative interface at the rear side of the light-emitting strip body by welding or line connection.

[0011] Preferably, the light-emitting bead group includes at least one light-emitting bead, and the light-emitting beads are connected in series.

[0012] Preferably, the light-emitting bead group further includes a control chip, and the control chip and the light-emitting beads are connected in series.

[0013] Preferably, the positive line, the negative line and the independent line between adjacent light-emitting strip bodies are connected through adjacent positive interfaces, negative interfaces and independent line interfaces.

[0014] The beneficial effects of the light strip with equal brightness of the present utility model are as follows:

[0015] 1. By arranging an additional independent line, it is possible to make the sum of the line lengths from each light-emitting bead group to the input line and the output line of the external line equal, so that the line resistance between the light-emitting bead groups is consistent for a consistent light-emitting effect.

[0016] 2. By respectively arranging a positive interface, a negative interface and an independent line interface at both ends of the positive line, the negative line and the independent line, for a light strip with equal brightness and a shorter length, it can be realized by cutting, and for a light strip with equal brightness and a longer length, it can be realized by splicing.
