Detailed Description

For further understanding of the features and technical means, as well as the specific objects and functions of the present invention, the present invention will be described in further detail with reference to the accompanying drawings and detailed description.

Refer to fig. 2. The utility model provides a colored LED lamp area, has crust 4, and the parcel has flexible circuit board 3 in the crust 4, and the welding has many colored LED lamp pearls 1 and resistance 2 on the flexible circuit board 3.

Refer to fig. 3. The colored LED lamp bead 1 is internally provided with three LED chips 1R/1G/1B with different colors of red, green and blue in a sealing way, and the LED chip 1R/1G/1B with each color is provided with a positive lamp base 14/15 and a negative lamp base 14/15 which extend out of the LED lamp bead 1. Of course, the LED chips 1R/1G/1B with the three different colors can also be packaged separately to form LED lamp beads with three colors of red, green and blue.

Refer to fig. 4 and 5. A circuit structure of a colorful LED lamp belt can connect one LED chip or two to ten LED chips 1R/1G/1B with the same color in series through a positive electrode lamp base 14/15 and a negative electrode lamp base 14/15 to form a color module, and two adjacent modules with different colors are connected in series. Taking three LED chips 1R/1G/1B as an example of a color module, three green LED chips 1G are connected in series to form a green module 10G/11G/12G/13G … …, three red LED chips 1R and a resistor 2 are connected in series to form a red module 10R/11R/12R/13R … …, and three blue LED chips 1B are connected in series to form a blue module 10B/11B/12B/13B … …. To facilitate understanding of the connection manner of the LED string circuit, the present invention will be described in order with the left side shown in fig. 5 as a starting point. The green light module 10G is connected in series with its next adjacent red light module 11R, the red light module 11R is connected in series with its next adjacent blue light module 12B, and the blue light module 12B is connected in series with its next adjacent green light module 13G to form the LED series unit 11.
