Abstract

The present invention relates to the technical field of advertising and label, in particular to an LED area light source, which comprises a transparent or translucent board. Two ends of the transparent or translucent board are respectively provided with a circuit board. The circuit board is provided with a group of LEDs. Light shielding materials are respectively arranged above and under the LEDs. The irradiation light of the LEDs irradiates into the inner of the transparent or translucent board. At least a side of a front side or a back side of the transparent or translucent board is provided with a logo. The logo arranged on the front side of the transparent or translucent board is a light-permeation logo. The present invention solves the technological problems of high price and large energy consumption of the existing fluorescent lamps or energy-saving lamps used for the label and advertising board as the light source, and not only has low cost and energy consumption but also has even and soft light.

Description

technical field [0001] The invention relates to the technical field of advertisements and signs, in particular to an LED surface light source. Background technique [0002] Most of the existing signs and billboards, such as office signs, classroom signs, shopping mall instructions, safe passage signs, road sign instructions, rules and regulations, and advertising posters, have no light source and can only be seen with the help of natural light (sunshine) or external lighting. Clearly, these signs, indication signs and billboards etc. are just useless in the absence of external lighting at night. Some have to use expensive, energy-consuming, heavy and short-lived fluorescent lamp boxes in order to be equipped with light sources; The power is still quite amazing. For this reason, people try to use LED as the light source of advertising light box or signboard, disclose a kind of " synchronously flashing traffic signal signs group " as Chinese patent CN1388487A, it uses a larg...
