Description

Technical Field

[0001] The utility model relates to a fire-fighting lamp, in particular to an emergency evacuation lighting lamp used in a fire-fighting passage. Background Art

[0002] At present, emergency evacuation lights need to be installed on the fire emergency passages of subway tunnels. First of all, these lights are installed on the wall about 3.5 meters above the ground. Since the lights themselves do not focus, and in order to ensure that there is no lighting blind spot between two adjacent lights, when the light shines on the ground, some of the light will inevitably shine on the opposite wall. However, in practice, it is only necessary to ensure that there is enough illumination in the ground area. Therefore, these lights shining on the opposite wall cause a waste, which leads to high power of the lights in the entire tunnel and high construction costs of the tunnel. Utility Model Content

[0003] The technical task of the utility model is to provide an emergency evacuation lighting lamp for fire passages in view of the above deficiencies in the prior art.

[0004] The technical solution adopted by the utility model to solve the technical problem is: an emergency evacuation lighting lamp for a fire passage, comprising a lampshade and a lamp holder, the back of the lamp holder is a flat structure, the front of the lamp holder is an arc-shaped structure, an adjustment frame is provided on the front of the lamp holder, four lamp bodies are provided on the adjustment frame, the lamp bodies on the left and right sides are symmetrically arranged, a light source is provided in the lamp body, a lens is provided at the front end of the light source, a beam angle β of the lenses in the two middle lamp bodies is 30°, and a beam angle α of the lenses in the two outer lamp bodies is 20°.

[0005] Further improvement: the angle between the bottom of the two lamp bodies in the middle and the back of the lamp holder is β1=16°, and the angle between the bottom of the two lamp bodies on the outside and the back of the lamp holder is α1=42°.

[0006] The advantages of the utility model are as follows: because a lens is arranged in front of the light source, and the lens can focus the emitted light onto the road surface, so as to avoid the light being scattered to places outside the road and causing light waste, the power required for the lamp can be effectively reduced, thereby achieving energy-saving effects. Therefore, compared with the existing lighting lamps, while meeting the same lighting requirements on the ground, the power of a single lighting lamp can be reduced, thereby reducing the total power of all lighting lamps in the entire tunnel. In this case, the diameter of the cable used to connect the lighting lamps can also be reduced accordingly, which not only reduces the cost of the cable, but also reduces the difficulty of construction.

[0007] Because the total power of the lighting is reduced, the power consumption of the lighting in the entire tunnel is reduced, thereby saving electricity costs. In addition, in an emergency, when the main power is turned off, the lighting in the tunnel is powered by backup batteries. Therefore, in this case, the reduction in lighting power can also extend the life of the backup battery, providing basic protection for safe escape from the tunnel. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The utility model is described in detail below in conjunction with the accompanying drawings.

[0014] As shown in the figure, an emergency evacuation lighting lamp for a fire passage includes a lampshade 1 and a lamp holder 2, wherein the back of the lamp holder 2 is a flat structure, and the front of the lamp holder 2 is an arc-shaped structure. An adjustment frame 3 is provided on the front of the lamp holder 2, and four lamp bodies 4 are provided on the adjustment frame 3. The lamp bodies 4 on the left and right sides are symmetrically arranged, and a light source 5 is provided in the lamp body 4. A lens 6 is provided at the front end of the light source 5. The beam angle β of the lenses in the two middle lamp bodies 4 is 30°, and the beam angle α of the lenses in the two outer lamp bodies 4 is 20°.

[0015] The angle between the bottom of the two lamp bodies 4 in the middle and the back of the lamp holder 2 is β1=16°, and the angle between the bottom of the two lamp bodies 4 on the outside and the back of the lamp holder 2 is α1=42°.

[0016] The working principle is as follows: after the lamp holder 2 is installed, the position of the lamp body 4 is adjusted by adjusting the bracket 3 so that the light can completely illuminate the ground. The two lamp bodies 4 located on the outside are the outer lamp bodies 42, and the two lamp bodies 4 located in the middle are the inner lamp bodies 41. At this time, since the height of the outer lamp body 42 from the ground is higher than that of the inner lamp body 41, when the lamp body 4 illuminates the ground, the angle between the outer lamp body 42 and the irradiated surface is larger than that between the inner lamp body 41 and the irradiated surface, but the beam angle of the lens 6 in the outer lamp body 42 is larger than that of the inner lamp body 41. The beam angle of the inner lens 6 is small, so the range of each lamp body 4 irradiating the ground is basically about 2.5 meters, and the irradiation range of four lamp bodies 4 can reach 10 meters. Therefore, when designing and installing, the lighting lamps can be installed at intervals of 10 meters. At the same time, under normal circumstances, the width of the road surface in the fire passage is about 2.4 to 2.6 meters, so when the lamp body 4 has an irradiation width of 2.5 meters, it can just complete the illumination of the effective area of ​​the road surface, which not only ensures the effective irradiation surface of the road surface, but also prevents the waste of light source.

[0017] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
