If there is a description of "first" or "second", it is only used for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0018] Reference Figures 1 to 3The utility model discloses an LED lamp board, including multiple groups of LED circuits, each group of LED circuits has an operating voltage of U1, each group of LED circuits includes U1 / 6 or U1 / 24 dual-chip lamp beads connected in series and a resistor R1, and the dual-chip lamp beads include two LED chips connected in series. In conventional use, the operating voltage U1=24V, each group of LED circuits includes 4 dual-chip lamp beads LED1 connected in series, the starting voltage of each dual-chip lamp bead is 5.4V, the voltage division on the resistor R1 is 3.4V, the current of the resistor R1 is generally 10 mA, and the current of the resistor on the existing LED lamp board is 20 mA, which significantly reduces the loss and improves the light effect. Due to the use of dual-chip lamp beads connected in series, the voltage division of each lamp bead is twice that of the original single-chip lamp bead, which can effectively improve the light effect to 150lm / W, and at the same time reduce the voltage division on the resistor R1, thereby reducing the loss and reducing the heat of the LED lamp board. Compared with the existing LED light boards, the number of lamp beads is significantly reduced, and the length of the LED light boards is shortened. Using shorter LED light boards can achieve brighter lighting, saving materials and space.

[0019] In some embodiments, the operating voltage U1 = 36V, and each LED circuit includes 6 double-chip lamp beads connected in series.

[0020] In some embodiments, the lamp bead is directly made into a single-chip lamp bead with a rated voltage of 6V to achieve a lighting effect equivalent to that of a dual-chip lamp bead.

[0021] like Figure 3 For lamp beads with a rated voltage of 24V, only one 24V dual-chip lamp bead LED2 is needed to achieve high luminous efficiency. The cutting length of the light strip is one lamp per cut, which saves length and is easy to cut.

[0022] The present application also includes a light strip, which includes a soft light shell, and the LED light board is arranged in the soft light shell. The light strip has low loss, high light efficiency and saves length.
