The specific embodiment

Cooperate appended graphic explanation in detail by specific embodiment below, so that the effect that is easier to understand the purpose of this utility model, technology contents, characteristics and is reached.

Fig. 1 is the structural representation of the LED flexible water striation of surface coating described in the utility model; LED flexible water striation comprises flexible PCB plate 1, a plurality of paster LED 2 on the flexible PCB plate 1, a plurality of Chip-R 3 and colloid layer 4 that is arranged on the flexible PCB plate 1 of being arranged at, colloid layer 4 covers in the light-emitting area of flexible PCB plate 1, just is provided with the one side of paster LED 2 and Chip-R 3.

Production needs the LED flexible light stripe 9 of length, external form as shown in Figure 2, comprise a very soft pcb board 1, weld a plurality of 0603 type LED 2 and a plurality of resistance 3 on the flexible PCB plate, the side, two ends also is provided with the joint 6 that data wire 5 is connected with 12V or 24V power supply.Because the production of LED flexible light stripe is more general product in the industry, its concrete production process and technology are no longer too much told about at this.
