With the gradual improvement and maturity of LED semiconductor light source technology, as well as the popularization of energy-saving and environmentally friendly low-carbon concepts, LED light sources will gradually replace traditional lighting and advertising light sources such as light bulbs, energy-saving lamps, light lamps, and neon lights for advertising.

The traditional neon lights, due to the limitations of the production process and electrical principles, make the traditional neon production process cumbersome, costly, complex on-site installation and construction, high energy consumption, high electricity costs for users to use, and the lighting lines are It consists of one segment and lacks continuity; the failure rate is high and the service life is not guaranteed.

The existing advertising light boxes (including advertising letters and illuminating patterns) basically place a light source (FI light or LED light source) in the light box, and the surface of the light box is plated with corresponding light transmission characteristics and covered with corresponding colors and patterns. Cover, causing the pattern to glow. This kind of advertising light box is limited by the structure and the irrational setting of the light source, so that the overall luminous intensity is limited, the light effect is seriously wasted, and it is difficult to achieve the ideal advertising light effect, thereby causing energy waste.

Nowadays, the LED electronic light box on the market directly exposes the LED to display the light pattern in the form of LED dot matrix, which makes the light glare, the spot is obvious, the light pollution is serious, and the overall lighting advertisement visual appearance is not high.

Later, some so-called neon lights and soft lights with plug-in LED lamp beads as light sources appeared on the market. In the process of user use, some fatal defects were found. First, the complex internal structure of such lamps caused the lamps to be in the process of production. The processing technique is cumbersome, and not only a plurality of wires need to be programmed, but each LED lamp bead not only needs to be manually welded on the wire, but also needs to be fixed by a special structure in the process of encapsulation, which has high cost and low production efficiency; The LED lamp bead in the luminaire is completely wrapped in the plastic and cannot be dissipated, and the life of the LED luminaire largely depends on the heat dissipation structure and characteristics of the luminaire, which results in a compromise of the stability and life of the luminaire; And the characteristics of the structure, resulting in complex procedures in the installation process, the lamps need to be frequently cut off and continued according to the actual application conditions (including the circuit part), so that the flexibility of use of the product is greatly limited, the most important is the use of lamps The structure determines the fixing ability and bending performance of the lamp, and the line positioning cannot be refined. The bending radius is limited, etc., so that the LED neon and soft light can not meet the needs of pattern or text design very well, so it has not been universalized.

Then, the patch LED lamp bead (10) in the LED string is first embedded in the light-transmitting strip (3), and then all the LED beads are connected to the corresponding driving power source according to the embodiment described in Embodiment 1. The connecting wire may be routed along the bottom of the groove (5), or a plurality of wire holes may be arranged at the bottom of the groove (5) through the back of the base, and the wire is connected to the LED light string and the driving power source through the outlet hole. Then, the light-transmitting strip (3) embedded with the LED light-emitting string is embedded in the groove (5) from the front surface of the base. For the remaining implementation steps, refer to Embodiment 1.

The LED lighting strings described in this embodiment may be of various types as shown in Fig. 1.

Example 13

Several other LED lighting strings as shown in Fig. 1 and light-transmitting strips (3) of several structures as shown in Fig. 2 can be constructed by referring to the corresponding methods described in the corresponding embodiments above.
