Description

Technical Field

[0001] The invention belongs to the technical field of lighting devices, and in particular relates to an independent emergency light. Background Art

[0002] Independent emergency lamps are special lighting lamps with built-in lead-acid batteries (hereinafter referred to as "batteries"). Under normal power supply conditions, the lamps charge, float charge and automatically maintain the built-in batteries. Only when the lighting power supply system is completely powered off, the battery they carry will be used to provide emergency lighting. They are mainly used in places where emergency lighting is required, such as ship stairways, passages, and important cabins. Existing independent emergency lamps are generally only fixed in fixed positions to provide light sources to the surrounding environment. Affected by the use environment, the light in the corners is generally dark. In this way, when the lighting power supply system is completely powered off, once something needs to be dealt with and sufficient light is required, only other lighting equipment such as flashlights can be used to assist in the handling. The complete power outage of the lighting power supply system is a special case, so it is not common. In addition, when the lighting power supply system is completely powered off, emergency lamps can generally meet people's lighting needs. Therefore, people generally do not use backup flashlights and other backup lighting. In this way, once something needs to be dealt with and sufficient light is required under the condition that the lighting power supply system is completely powered off, people will often delay the handling of things by temporarily looking for flashlights or other lighting equipment.

DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0019] The present invention provides a stand-alone emergency light. Figures 1 to 3, including a lamp housing 1 and a connecting plate 2, the lamp housing and the connecting plate are detachably connected, and in this embodiment, the lamp housing and the lamp holder can use existing connection methods, such as a slot and strip connection method, a screw or bolt fixing method, etc.; an incoming line connector 3 is provided on the lamp housing, wherein one or more incoming line connectors can be provided, and a fixing plate 4 is provided in the lamp housing, and the fixing plate divides the internal space of the lamp housing into a first accommodating space 5 and a second accommodating space 6 that are interconnected, and an LED light board 7 is installed on one side of the fixing plate, wherein the LED light board can also be replaced by other light sources, and the LED light board is located in the first accommodating space, and the first accommodating space is located on the side of the lamp housing away from the connecting plate, wherein the side lamp housing is transparent so that light can be transmitted outward; a bobbin 8 is installed on the other side of the fixing plate, and the bobbin is fixed in the second accommodating space by a torsion spring 9, so that the wire on the bobbin can be reset after losing tension after being pulled out.

[0020] When in use, the above-mentioned independent emergency light can fix the connecting plate on the wall, and the wire is wound on the spool of the emergency light. One end of the wire is connected to the LED light board, and the other end is connected to the incoming line of the light. When temporary mobile lighting is needed, the lamp housing can be removed, and the wound wire can be pulled out through the incoming line connector so that the lamp housing part can be easily moved, so that it can be used as a temporary mobile light source, which is more convenient to use. In addition, the second accommodating space is connected to the first accommodating space, which not only provides installation space for the spool, but also expands the heat dissipation area of ​​the LED light board, and the heat dissipation effect is relatively good.

[0021] As an implementation mode, one side of the lamp housing close to the connecting plate protrudes outward at a middle position to form a protrusion 10, the protrusion is arranged almost flush with the connecting plate, a groove 11 is arranged at a middle position on the inner side of the protrusion, one end of the bobbin is rotatably connected to the protrusion, and the other end is rotatably connected to the fixing plate; a first torsion spring is arranged between the bobbin and the protrusion, the first torsion spring is located in the groove, a second torsion spring is arranged between the bobbin and the fixing plate, the first torsion spring and the second torsion spring form the above-mentioned torsion spring, when fixing the connecting plate, this structure fixes the two ends of the connecting plate to the wall, after fixing, since the protrusion is flush with the connecting plate, the protrusion forms a support for the lamp housing at the middle position, so that the lamp housing is fixed more stably, when the lamp housing is removed for use, the protrusion can be used as a handle, in order to prevent the protrusion from absorbing a high amount of heat from the LED lamp board, the depth of the groove is between 1 / 6-1 / 4 of the thickness of the protrusion, of course, a heat insulating sleeve can also be arranged on the protrusion for use.

[0022] In this embodiment, the inlet connector can use a waterproof gland. For ease of use, the applicant has also designed an inlet connector, see Figure 4The inlet connector includes a base 12, a rubber ring 13 and a top cover 14. The bottom end of the base extends outward to form a blocking portion. The outer surface of the base is provided with an external thread 15. The inner side surface of the base is symmetrically provided with an arc groove 16. The end position of the arc groove is provided with a folded edge 17; the base is divided into two parts with the vertical plane where one of the diameters of the base is located as the reference plane, and the reference plane divides the arc groove into two parts. An elastic support strip 18 matching the size and shape of the arc groove is provided in the arc groove, and a central groove or a central hole is provided in the middle position of the elastic support strip. A shaping strip 19 is provided in the central groove or the central hole, and the top of the shaping strip The top cover extends out of the central groove or the central hole and a first fixing hole 20 is arranged on the top of the shaping strip; the inner side surface of the top cover is provided with an internal thread matching the external thread, the top surface of the top cover is provided with an annular hole 21 for the shaping strip to pass through, and the outer side of the annular hole is provided with a positioning plate 22 matching the shaping strip. Generally, multiple pairs of positioning plates can be provided, and the positioning plate is provided with a second fixing hole 23 matching the first fixing hole; the inner surface of the central groove or the central hole and the outer surface of the shaping strip are smooth, so that the shaping strip can be inserted into the central groove or the central hole and can be pulled out, and in the inserted state, there is a gap between the two parts of the base. When the structure is in use, the shaping strip is inserted into the elastic support strip, the top portion passes through the annular hole and is exposed outside the top cover, the base passes through the hole on the lamp housing for fixing the incoming line connector and is then covered with a rubber ring, and then the elastic support strip is inserted into the arc groove, the top cover is rotated to be connected to the base through a thread, and the top of the positioning plate and the shaping strip is fixed through the first fixing hole and the second fixing hole, and can be fixed with a pin when fixing, which is convenient for removal; when it is necessary to pull out the wire on the spool, the pin is removed to pull out the shaping strip, so that the elastic support strip shrinks inwardly, and the gap between the two parts of the base is reduced to close, so that the top cover can be easily removed; in addition, when the mutually matching threads are rusted, due to the isolation of the elastic support strip, the rusted parts cannot form a whole in the circumferential direction, and the shaping strip is pulled out, so that the elastic support strip shrinks inwardly, so that the two parts of the base lose the mutual support force, so it is easier to separate the top cover and the base by force, to prevent the mutually matching threads from rusting and being unable to separate the top cover and the base, and the elastic support strip in this embodiment can be made of rubber or silicone.

[0023] In order to make the elastic support strip easier to get stuck in the arc groove, the angle formed by the folded edge and the arc groove can be set to be less than 90°. The angle formed by the folded edge and the arc groove described here is the angle between this side and the chord of the arc groove.

[0024] To facilitate installation of the top cover, the bottom of the top cover can be extended outward to form an inclined surface, and the internal thread is arranged above the inclined surface, so that the diameter of the bottom of the top cover is larger than the diameter of the base, so that it can be more easily covered on the base and screwed.

[0025] It should be emphasized that the protection level of the independent emergency light of the present invention is IP56. In order to achieve this protection level, the design principle for the protection level of the lamp IP56 should be to open as few or no through holes as possible in the lamp. Since the lamp needs to be wired, light-distributed and quickly replaced with batteries, the holes that have to be opened are as follows:

[0026] a. Connection between lampshade and housing:

[0027] This part is the key protection part. We use sealing ring plus thread (internal thread of shell and external thread of lampshade) for sealing. The sealing ring adopts the sealing method similar to the car sunroof.

[0028] b.Electrical interface:

[0029] For the electrical interface, our company symmetrically opens two identical rectangular holes, each adopts an integrated design of two stuffing boxes and terminal posts with a protection level of IP56. The connection with the shell is achieved through 4 M4 screws and sealing rings to achieve the protection level.

[0030] c.Battery quick replacement interface:

[0031] The battery quick-change interface uses the same sealing method as B, fixed with 4 M4 screws, and the sealing ring used is slightly different.

[0032] d. Install the fixing plate interface:

[0033] Since the weight of the lamp does not exceed 2Kg, the connection between the fixing mounting plate and the shell is achieved by drilling four M5 threaded blind holes on the shell and fixing the mounting adapter plate of the lamp with M5 hexagonal screws.

[0034] The above-mentioned embodiments only express the implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be based on the attached claims.
