Technical Field

[0001] The utility model relates to a three-defense fire emergency sign lamp, belonging to the field of fire lamps. Background Art

[0002] Fire emergency sign lamps are a type of lighting products that provide instructions for personnel evacuation and fire fighting operations. It usually uses the mains power to convert into a safe voltage for power supply, and automatically switches to battery power supply when the power is off. Such fire emergency sign lamps are generally configured in crowded places such as large buildings, shopping malls, airports and stations. The three-proof sign lamps designed in this design have the characteristics of high shell protection level, low power consumption, high brightness and long service life. However, during use, due to environmental influences, it is easy to have insufficient brightness, which is not conducive to the normal use of the lamp and its guidance function in an emergency. Utility Model Content

[0003] The purpose of the utility model is to overcome the shortcomings and deficiencies of the prior art and to provide a triple-proof fire emergency sign lamp.

[0004] A triple-defense fire emergency sign lamp comprises a base plate, a light source board and a panel with an indication function, wherein the panel and the base plate cooperate to form a light cavity, the light source board is mounted at the bottom of the light cavity, the base plate comprises a mounting surface constituting the light cavity, the mounting surface is arranged to be inclined toward the light cavity, and the light source can be more evenly reflected onto the panel by tilting the mounting surface of the base plate, thereby compensating for the distance of the panel far from the light source board, making the entire light cavity emit light more evenly, ensuring that the brightness of the panel pattern meets the requirements of national standards, and will not cause uneven brightness under environmental influences, which will cause problems with service life.

[0005] Furthermore, the distance between the mounting surface away from the end of the light source board and the panel is greater than the distance between the mounting surface close to the light source board and the panel, thereby reducing the distance between the far end of the optical cavity and the panel to average the reflection intensity of the panel in the optical cavity and ensure the normal emission of light on the panel to play a guiding role.

[0006] Preferably, a plurality of light emitting lamps are arranged at intervals on the light source board. The light emitting lamps may be light sources such as LED light sources that can emit light continuously and stably, have low power consumption, are easy to maintain, and save production and use costs.

[0007] Preferably, the base plate includes a frame for fixing the panel, the frame is provided with a first fixed sealing ring groove surrounding the light cavity, a second sealing ring groove is provided around the first sealing ring groove, the first sealing ring groove is used for sealing connection with the glass panel, and the second sealing ring groove is used for sealing connection with the stainless steel panel. The first sealing ring groove and the second sealing ring groove can be installed in conjunction with panels of different materials, and can increase the waterproofness and dustproofness of the lamp, preventing the lamp from being damaged by water and dust.

[0008] Preferably, the depth of the first sealing ring groove is greater than that of the second sealing ring groove. The glass panel is inconvenient to drill and needs to be embedded in the base plate for fixed installation. The second sealing ring groove can provide auxiliary sealing to help the glass material to be better sealed.

[0009] Furthermore, the first sealing ring groove and the second sealing ring groove are both sealed and connected to the panel via a sealing rubber strip. The sealing rubber strip is low in cost and easy to obtain, thereby reducing the manufacturing cost.

[0010] Furthermore, the frame is provided with a fixing plate for fixing the glass panel, and the fixing plate is connected to the frame by bolts. The fixing plate can help the panel made of glass to be fixedly installed on the frame.

[0011] Preferably, fixing blocks are provided at intervals on the bottom plate, and slots are provided on the fixing blocks. The light source board is plugged and fixed in the slots, so that the light source board can be stably installed in the slots without shaking.

[0012] The beneficial effects of the utility model are as follows: by tilting the mounting surface of the base plate, the light source can be reflected onto the panel more evenly, compensating for the panel far away from the light source board, making the entire light cavity emit light more evenly, ensuring that the brightness of the panel pattern meets national standards, and preventing uneven brightness due to environmental influences, which will cause problems with service life.
