Description

Technical Field

[0001] This utility model relates to the field of LED light strip technology, specifically a side-emitting LED lens light strip with high-voltage AC input. Background Technology

[0002] LED light strips refer to LEDs assembled on strip-shaped FPC (flexible printed circuit board) or PCB rigid board. Due to their long lifespan, energy efficiency, and environmental friendliness, LED light strips are gradually emerging in various advertising and decoration industries and lighting industries. With the popularization of LED light sources, the market has more ideas about the application of LED light sources in various environments and the angle of light emission. LED light strips that can achieve more light emission angles to match different scenarios and usage environments and improve the product's lighting effect can well meet the needs of various scenarios.

[0003] Existing LED light strips used in advertising light boxes generally emit diffuse light, shining from the back of the light box to the front. This makes it impossible to control the light emission angle. The installation of LED light sources requires covering the entire bottom of the light box, resulting in low installation efficiency and high cost. Utility Model Content

[0004] The purpose of this invention is to provide a side-emitting LED lens light strip with high-voltage AC input to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A high-voltage AC input side-emitting LED lens light strip includes a flexible circuit board. A plurality of LED beads are arranged at equal intervals on the flexible circuit board. The bottom of each LED bead is connected to the flexible circuit board via solder pads and is connected through circuitry on the flexible circuit board. A lens is mounted on the outer side of each LED bead to adjust its emission angle. The flexible circuit board is also connected in sequence via solder pads to a voltage regulating resistor, a pair of terminals, a wire-wound resistor, a varistor, a rectifier bridge, an LED constant current driver chip, a current sensing resistor, an electrolytic capacitor, a surface-mount inductor, and a surface-mount capacitor. These components are connected to circuitry on the flexible circuit board.

[0007] Preferably, the flexible circuit board is further provided with adhesive for lens mounting.

[0008] Preferably, the flexible circuit board is a single-sided circuit board, with several pads on the top for mounting various components, and an insulating layer at the bottom.

[0009] Preferably, the flexible circuit board is made of copper foil.

[0010] Preferably, the terminal on the left end uses a three-pin metal pin, and the terminal on the right end uses a two-pin metal pin, and the terminals are interconnected with the circuitry of the flexible circuit board.

[0011] Compared with the prior art, the beneficial effects of this utility model are: this utility model installs an adjustable light-emitting angle lens on the LED lamp beads so that the light can illuminate one or both sides of the light-emitting surface of the light box from the side.

[0012] This invention achieves unlimited product extension through LED flexible light strips, which are convenient and quick to install and use. They can be directly cut to the required length, reducing the frequency of power connection.

[0013] This invention uses a high-voltage AC input method, which greatly improves the voltage drop level and makes long-distance transmission possible.

[0014] This utility model enables direct connection to AC power without the need for a separate driver power supply, resulting in high installation efficiency, effective cost reduction, and the ability to meet various needs such as light box illumination and wall washing.
