[0028] In the embodiment, the indicating board 200 is provided with an indicating mark, the indicating mark carries indicating information, the indicating mark can be a layer coated on the surface of the indicating board 200 or a light guide mark on the indicating board 200, and is used for indicating a direction, for example, the indicating mark is an arrow direction pattern or an image pattern of an escape person.

[0029] The support shell 100 is used for being installed on a ceiling or a wall in a room, and the power supply module arranged in the support shell 100 is used for supplying power to the first indicating lamp 210 and the lighting lamp 300, and the power supply module includes a transformer, a rectifier, a battery, a power supply circuit board and the like, for example, the transformer is used for converting the voltage of commercial power into a suitable voltage, the rectifier is used for converting alternating current into direct current to supply power to the first indicating lamp 210 and the lighting lamp 300, and the battery is used for providing standby power, and after commercial power is cut off, the first indicating lamp 210 can be kept to work normally. The implementation technology of the power supply module belongs to the prior art, and the embodiment will not be described in detail.

[0030] In the embodiment, the indicating board 200 is arranged at the bottom of the support shell 100, the first indicating lamp 210 at the top of the indicating board 200 faces downward and emits light towards the indicating board 200, so that the indicating mark on the indicating board 200 emits light, thereby highlighting the indicating mark. The indicating board 200 can be a transparent plate, so that light can penetrate. In this way, the light emitted by the first indicating lamp 210 can be used as the backlight of the indicating mark on the indicating board 200, thereby highlighting the indicating mark.

[0031] In the embodiment, the illumination lamp 300 arranged at the bottom of the indication board 200 can illuminate downward, avoiding the influence on the indication illumination of the indication lamp. It should be understood that the brightness of the illumination lamp 300 is greater than the brightness of the first indication lamp 210, and if the illumination lamp 300 directly illuminates the illumination range of the indication lamp, the function of the indication lamp cannot be played. In some cases where weak backlight is required for the indication mark, the strong light of the illumination lamp 300 can cause the indication mark to be unable to be displayed. Therefore, in the embodiment, the illumination lamp 300 is arranged at the bottom of the indication board 200 and emits light downward, which can avoid the influence on the indication effect of the indication board 200, and the illumination lamp 300 can illuminate the security articles below.
