[0002] Fire emergency lights are a guarantee for public safety emergencies and are mandatory equipment for public fire protection. They have a wide range of applications and complex installation environments. Among them, fire emergency lighting lamps are usually installed at fire escape passages. When power outages, fires and other situations occur, they can automatically turn on the lights to achieve the emergency lighting function. However, in public buildings, whether it is the creation of the environmental atmosphere or the elegance of the appearance, fire emergency lighting lamps are inferior to conventional lighting lamps. Because fire emergency lighting lamps mainly focus on emergency lighting, and lamps that simultaneously possess both emergency functions and daily lighting functions need to be equipped with both driving components for driving light sources and emergency components for providing emergency functions, and the product cost is relatively expensive. Installing fire emergency lighting lamps in some places may cause the product to be too large in volume or not match the style, thus affecting the overall layout. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The technical solution of the present utility model will be further described below with reference to specific embodiments.

[0024] As Figure 1 , Figure 2 , Figure 3 , Figure 4As shown in the figure, a small emergency lighting lamp includes: a housing 1, provided with an opening 11, in a box shape, and provided with a light-transmitting hole 12; a circuit board 2, arranged inside the housing 1 through the opening 11, provided with an LED light source 21 and an emergency component 22, and the position of the LED light source 21 is adapted to the position of the light-transmitting hole 12; a cover 3, covering the opening 11. The overall structure is extremely simple, the assembly is convenient, the cost is low, the space of the housing 1 is fully utilized, the housing 1 is provided with a light-transmitting hole 12, and a circuit board 2 is arranged inside the housing 1, the product size is extremely reduced, it can be hidden in the environment of the place, is not conspicuous, and does not affect the style of the place. When an emergency occurs, the light of the LED light source 21 irradiates outward through the light-transmitting hole 12, and it has an emergency lighting function.

[0025] A lens 4 is arranged in the light-transmitting hole 12, the housing 1 is provided with a recessed light-emitting area 15 inward, and the lens 5 is arranged in the light-emitting area 15; the LED light source 21 is arranged in the light-transmitting hole 12; the number of the lenses 4 is three, and they are evenly arranged in a circular array. The lens 4 is fixed on the circuit board 2 by pasting, or the lens 4 is arranged on the housing 1 through a two-color injection molding process or a snap-fit structure. The lens 4 can increase the light efficiency of the LED light source 21, make the light efficiency better, and the light is fully utilized.

[0026] The position of the lens 4 is adapted to the position of the LED light source 21. The circuit board 2 includes a front side and a back side. The LED light source 21 is arranged on the front side of the circuit board 2, and the front side of the circuit board 2 is closely attached to the inner surface of the housing 1. The cover 3 is provided with a support post 31, and the support post 31 supports the circuit board 2. The emergency component 22 is arranged on the back side of the circuit board 2; this structure can make the LED light source 21 closer to the lens while reserving enough space for the placement of the emergency component 22.

[0027] The housing 1 and the cover 3 are both provided with a snap-fit structure 5 that matches each other, and the housing 1 and the cover 3 are snap-fitted with each other through the snap-fit structure 5 to form a closed box shape.

[0028] A reinforcing groove 13 is arranged on the edge of the housing 1, and an extension 32 that matches the reinforcing groove 13 is arranged on the edge of the cover 3. The extension 32 protrudes from the edge of the cover 3, and the extension 32 is arranged in the reinforcing groove 13. Since both the housing 1 and the cover 3 are made of plastic, and the plastic material is relatively soft and is prone to deformation when stressed, the reinforcing groove 13 and the extension 32 are for making the housing 1 and the cover 3 more firmly snap-fitted with each other after being assembled, thereby improving the overall strength of the product. The baffle surface 131 can prevent foreign objects from entering the inside of the housing 1 through the reinforcing groove 13 and improve the service life of the product.

[0029] The housing 1 is provided with a wire outlet hole 14. The reinforcing groove 13 and the extension part 32 are arranged on one side close to the wire outlet hole 14. The existence of the wire outlet hole 14 will damage the integrity of the housing 1. Therefore, by arranging the reinforcing groove 13 and the extension part 32 on the side where the wire outlet hole 14 is located, the strength of this part can be enhanced, thereby improving the overall strength of the product.

[0030] The foregoing is only the preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
