Abstract

The invention provides an integrated multidirectional LED light guide system which comprises a light guide structure and an LED light-emitting chip. The light guide structure is integrally formed and provided with multiple light guide paths, the LED light-emitting chip is bonded and fixed on a printed circuit board, the light guide structure is provided with a light receiving end and multiple illuminating ends, the light receiving end is adjacent to the LED light-emitting chip to receive a light source, the illuminating ends are respectively corresponding to keys or indicating buttons of an electronic product, and the light guide paths are formed between the light receiving end and the illuminating ends. By using the integrally-formed light guide structure with the light guide paths, the integrated multidirectional LED light guide system can obtain preset illuminating effect only by using a single LED or few LEDs at little cost; in addition, by the design, a circuit board structure using multiple LED perforated structures is also simplified.

Description

technical field [0001] The invention relates to an optical lighting structure, in particular to an integrated multidirectional LED light guide system with simple structure and low cost. Background technique [0002] Current electronic and electrical products, including portable mobile communication products, handheld electronic products, and various household appliances, all have LED (light-emitting diode) indication or backlight functions, such as the backlight display of mobile phone buttons, and various function indications on household appliances. Button backlight display, etc. This backlight display or function indication structure generally uses one LED or uses one LED combined with a single light guide column to correspond to a key or an indication button. Such as figure 1 and figure 2 As shown, the display panel 100 of an electronic product has a plurality of function indication buttons 101 , 102 , 103 and 104 , and four LEDs 300 are correspondingly arranged on t...
