LED flickering device

Abstract

The invention discloses an LED flickering device which comprises a circuit board. LED light sources, anodes and cathodes are arranged on the circuit board, each anode and the corresponding cathode are conducted with the corresponding LED light source, a positioning plate which covers on the circuit board and is light-proof is disposed on the circuit board, a light guide plate component corresponding to positions of the LED light sources is arranged on the positioning plate and consists of at least one light guide plate, the LED light sources are used as background light source to transmit light or the LED light sources are used as working display light sources to transmit light by the aid of the light guide plates, an optical filter covers on the light guide plate component, and a light-transmitting pattern layer covers on the optical filter. When the LED light source are luminous, the integral light guide plate component forms a uniform luminous surface; the light guide plate component with a single layer can be directly used as the background light source to emit light for an independent luminous area; two or more layers of light guide plates can be combined and stacked to form a light source to emit light when the LED flickering device is used in a luminous area with cross superposition or other complicated relations, various suitable luminous shapes and effects are realized after change, and an optimal luminous effect is achieved.

Description

technical field [0001] The invention relates to an LED flashing device, in particular to an indoor or outdoor light box advertising facility and a small LED flashing product. Background technique [0002] The advertisement forms of present flashing light boxes are mostly made with technologies such as neon lights and electroluminescent materials. Its particularly prominent disadvantage is that the light source needs to be replaced every time the screen is changed, so the actual operating cost is relatively high and the advertising time is long. Advertisers often need to pay twice or even more than the usual production fee to choose this form of advertising. Then for the release of seasonal products, this contradiction is particularly prominent. [0003] Circuit boards are mainly used in the connection parts of electronic products, which have many advantages such as saving space, reducing weight and high flexibility, and are widely used in portable devices (such as mobile p...

Problems solved by technology

[0005] The display boards or flashing light boxes on the market all use fluorescent tubes or LED lights to achieve illumination. These display boards or flashing light boxes are all organic boards with patterns or words, and the color effects are monotonous, lack of change, and the effect is single

However, the existing display boards or flashing light boxes can only have one type of light in one area, and the light effect is single, which fails to achieve the effect of multi-layer light or a combination of multiple light.
