Multifunctional lighting emergency mark

Abstract

The invention discloses a multifunctional lighting emergency mark which comprises a light guide plate, a light-emitting diode (LED) light bar composed of a plurality of LEDs, a reflection increasing layer, a transmitting film or transmitting light reflection film, a deep color film or deep color light reflection film, an emergency power supply and a control circuit. The light guide plate comprises a transparent plate, the reflection increasing layer is arranged on a surface of the back of the transparent plate, the LED light bar is installed on a lateral face of the light guide plate, the LED light bar is connected with a power supply and a controller through a lead, the deep color film or deep color light reflection film is arranged on an outer surface of the front face of the light guide plate, and images and texts are hollowed on the deep color film or deep color light reflection film. The transmitting reflection increasing layer is arranged on the surface of the front face and / or the back face of the transparent plate to enable light given out from the LED light bar to produce a passive lighting reflection face on the transmitting reflection increasing layer, the multifunctional lighting emergency mark initiatively lights at night, luminance of a safety mark can be obviously improved, indicating effects are strengthened, a lighting stripe for lighting can be further increased, and the multifunctional lighting emergency mark can be widely used for various emergency marks such as fire control.

Description

technical field [0001] The invention relates to an emergency sign. Background technique [0002] Old-fashioned emergency signs, such as fire emergency safety signs, are mostly only marked with safety exits, direction arrows, etc. At present, there are some luminous emergency signs, which mostly use light box structure or EL luminous belt, light box emergency Signs have defects such as high power consumption and large volume, while EL light-emitting strips have insufficient brightness, etc., and emergency lights need to be used in combination. Contents of the invention [0003] The problem to be solved by the present invention is to provide a multi-functional luminous emergency sign with small volume, low cost, and simultaneously realizing sign and lighting functions. [0004] The technical solution adopted in the present invention is: the multifunctional luminescent emergency sign includes a light guide plate, an LED light bar composed of multiple LEDs, an anti-reflection...
