[0002] Fire emergency lights are a guarantee for emergency safety in public places and a mandatory measure for public firefighting. They are used in a wide range and have a relatively complex layout. Fire emergency lighting is usually installed in fire escape passages. When power outages or fire alarms occur, the lights can be automatically turned on to achieve emergency lighting functions. The existing fire emergency double-head lights consist of a light box and two lamp heads installed on the light box. A light source board with an LED light source is placed in the lamp head. The light box is used to store a driver board that provides emergency lighting functions and drives the LED light source. The structure is large in size and has a single shape, which cannot meet people's increasingly changing aesthetic tastes.

DETAILED DESCRIPTION

[0031] The technical solution of the present utility model is further described below in conjunction with specific embodiments.

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, a new type of double head lamp comprises: a housing 1, provided with a lamp head 2, the lamp head 2 is provided with a light exit hole 21; a rear cover 3, covering the housing 1; a light-transmitting member 4, arranged between the light exit hole 21 and the rear cover 3 through a first fixing mechanism; a light source board 5, arranged behind the light-transmitting member 4 through a second fixing mechanism; a driving board 6, arranged between the housing 1 and the rear cover 3; wherein the light-transmitting member 4 is arranged at an angle relative to the surface of the housing 1, and the light-transmitting member 4 and the light source board 5 have the same angle of inclination with the light exit hole 21. Fixing the light exit angle of the light-transmitting member 4 simplifies the structure of the double head lamp, reduces the accessories of the entire lamp, shortens the assembly time, and reduces the product cost.

[0033] The light-transmitting member 4 is provided with a raised lens arc surface 41, and the lens arc surface 41 protrudes from the light exit hole 21. The light source plate 5 is provided with an LED light source 51, and the light of the LED light source 51 is emitted through the lens arc surface 41. The lens arc surface 41 is in the shape of a long strip. The light of the LED light source 51 emitted after passing through the lens arc surface 41 is in the shape of a long strip. The double headlights are mounted on the wall and irradiate the aisle. In order to avoid the waste of light caused by the long strip of light irradiating the wall, the light-transmitting member 4 is vertically tilted, and the tilt angle is between 40°-60°. The tilt angle of the light-transmitting member 4 is immutable.

[0034] The light-transmitting member 4 includes a support plate 42 extending outward from the periphery of the lens arc surface 41, and a waterproof groove 43 formed around the lens arc surface 41 is provided on the support plate 42; the inner surface of the lamp holder 2 is provided with a fixed edge 22 protruding upward and formed around the light exit hole 21, and the fixed edge 22 is arranged in the waterproof groove 43. Waterproof glue is poured into the waterproof groove 43 and then assembled behind the lamp holder 2. At this time, the fixed edge 22 should be arranged in the waterproof groove 43. This structure can prevent water vapor from entering the interior of the lamp body through the light exit hole 21, improve the protection level of the product, and ensure the service life of the lamp body. The light-transmitting member 4 can also be firmly and tightly arranged on the lamp holder 2 through the mutual engagement between the waterproof groove 43, the waterproof glue and the fixed edge 22. The support plate 42 is provided with a glue-avoiding groove 44 formed around the lens arc surface 41, and the glue-avoiding groove 44 is arranged between the lens arc surface 41 and the waterproof groove 43; during production, waterproof glue needs to be poured into the waterproof groove 43 first, and then the light-transmitting component 4 poured with waterproof glue is installed behind the lamp head 1. Since the fixed edge 22 needs to be embedded in the waterproof groove 43, the light-transmitting component 4 cannot be assembled after the waterproof glue is solidified. Therefore, when assembling the light-transmitting component 4, the waterproof glue may flow out of the waterproof groove 43. The glue-avoiding groove 44 can block the outflow of the waterproof glue, thereby preventing the waterproof glue from flowing to the lens arc surface 41 and affecting the light effect of the product.

[0035] The housing 1 is made of plastic integrally molded. Due to the inclination angle of the light exit hole 21 and the limitation of the processing technology, the inclination angle of the fixed edge 22 is equal to the inclination angle of the light exit hole 21, the mold will not be able to be demolded in parallel, and the product will not be produced. Therefore, the inclination angle of the fixed edge 22 is greater than the inclination angle of the light exit hole 21; and / or, the surface of the fixed edge 22 is parallel to the horizontal plane; and / or, the surface of the part of the fixed edge 22 with the largest distance from the rear cover 3 is parallel to the horizontal plane. This structure can ensure that the mold can be moved out in parallel, ensure that the product can be produced smoothly, and has a simple structure.

[0036] There is an angle between the fixed edge 22 and the lamp holder 2, and the angle between the fixed edge 22 and the part with the largest distance from the back cover 3 is the smallest. However, during production, the mold must be set within the angle before injection molding can be performed. In order for the mold to be generated and used, the inner surface of the lamp holder 2 is provided with an inwardly recessed ejection groove 23. The ejection groove 23 is arranged between the part with the largest distance between the fixed edge 22 and the back cover 3 and the light exit hole 21. The ejection groove 23 can increase the angle between the fixed edge 22 and the part with the largest distance from the back cover 3, so that the mold can better enter the angle, the mold is better designed, and the production is simpler and more convenient.

[0037] An extended positioning end 24 is provided on the periphery of the fixed edge 22, and the light-transmitting member 4 is provided with a positioning groove 45 matched with the positioning end 24. The positioning end 24 and the positioning groove 45 can guide the light-transmitting member 4 to avoid the wrong assembly direction during production and assembly, thereby accelerating the assembly efficiency of the product.

[0038] The first fixing mechanism includes: a support plate 42 extending outward from the periphery of the lens arc surface 41 and a support surface 25 extending outward from the periphery of the light exit hole 21; a first buckle portion 26 protruding from the inner surface of the lamp holder 2 and a second buckle portion 46 provided on the light-transmitting member 4 and adapted to the first buckle portion 26; and a support portion 31 provided on the back cover 3 and extending toward the lamp holder 2 and resting against the back of the light source board 5. This structure enables the light-transmitting member 4 to be firmly and tightly arranged on the lamp holder 2.

[0039] The second fixing mechanism includes: a card plate portion 47 disposed on the back of the light-transmitting member 4 and protruding toward the rear cover 3; a positioning column 48 disposed on the back of the light-transmitting member 4 and protruding upward, and a positioning hole 52 disposed on the light source board 5 and matching the positioning column 48. The edge of the light source board 5 is snapped into the card plate portion 47, thereby achieving the purpose of fixing the light source board 5. The positioning column 48 and the positioning hole 52 can prevent the light source board 5 from moving after assembly, thereby improving the service life of the product.

[0040] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
