Abstract

The utility model relates to an emergency indicating light with spontaneous light, which is composed of a casing, a power supply converter, and a luminous display plate, wherein the luminous display plate is a multilayer structure with a light source and is composed of a transparent light guide plate, a spontaneous layer, a mark layer, a transparent protective layer, a reflection layer, a u-shaped reflection cover and a light source. The light source is arranged on one side face of the transparent light guide plate, and the light rays are injected from the side face of the transparent light guide plate and propagated in the transparent light guide plate; a semi-transparent spontaneous layer is coated or pasted on a plane of the transparent light guide plate; on one hand, the semi-transparent spontaneous layer acts the energy storage function for automatic luminescence when the electricity is cut off, on the other hand, the light rays in the transparent light guide plate are changed into diffusion reflected light, and clear character patterns can be reflected through the mark layer. Because the light rays can be propagated in the transparent light guide plate, the propagation loss is reduced, the light source utilization rate is improved, the electric power consumption is greatly reduced, the service life is extended, the volume is reduced, and the material is saved and the transportation and the installation are convenient. The self luminescent material is applied for simplifying the circuit and reducing the production cost, and the reliability can be further enhanced. The emergency indicating light with spontaneous light is particularly used for the environment which does not have light or has insufficient light.

Description

The autoluminescence Warning Mark lamp of meeting an urgent need

Affiliated technical field the utility model belongs to emergent Warning Mark light fixture, is specifically related to a kind of identification light with the emergent deixis of autoluminescence.
