As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
The invention provides a dimmable emergency lamp 10 based on the internet of things, as shown in fig. 1 and fig. 2, the dimmable emergency lamp comprises: the LED lamp comprises a lamp body 100, a lampshade 200, an LED lamp wick 300 and a heat dissipation part 400, wherein the heat dissipation part 400 is arranged on the lamp body 100, the LED lamp wick 300 is attached to the heat dissipation part 400, and the lampshade 200 covers the LED lamp wick 300.
As shown in fig. 3, the dimmable emergency light 10 based on the internet of things of the present invention further includes a controller; the controller comprises a main control chip 21, and a power module 22, a communication module 23 and a dimming control module 24 which are electrically connected with the main control chip 21. The dimming control module 24 is used for controlling the brightness of the LED lampwick 300. The power module 22 supplies power to the LED lamp 300 through the main control chip 21. The communication module 23 is used for transceiving wireless signals, and the communication module 23 is connected with an external control device 30 (e.g., a mobile phone) through the internet of things (as shown in fig. 4). The communication module 23 receives a control signal sent by the external control device 30, and transmits the control signal to the dimming control module 24 through the main control chip 21, so as to control the brightness of the LED wick 300.
It should be noted that the invention particularly adopts the internet of things to realize the signal connection between the emergency lamp and the mobile phone, which is considered that the mobile phone is a necessary and portable communication tool for almost everyone at the present stage, and the coverage of the network is wide, and the brightness of the emergency lamp can be conveniently adjusted by the mobile phone. The traditional method of realizing the brightness of the emergency lamp through the remote controller has the defect that the loss rate of the remote controller is higher, so that the method cannot well meet the requirements of the times.
As shown in fig. 5 and 6, the heat dissipation member 400 includes: the lamp comprises a protective outer cover 410, an insert radiator 420 and a heat radiation fan 430, wherein the protective outer cover 410 is a hollow structure with two open ends, the protective outer cover 410 is connected with the lamp body 100 and the lamp shade 200, the insert radiator 420 and the heat radiation fan 430 are accommodated in the protective outer cover 410, and the side wall of the protective outer cover 410 is provided with a heat radiation through hole 411.
In this embodiment, the insert sheet heat sink 420 includes a flat plate portion 421 and an insert sheet portion 422 integrally formed with the flat plate portion 421, the led wick 300 is attached to the flat plate portion, and the heat dissipation fan 430 is attached to the insert sheet portion 422. Preferably, a plurality of heat dissipation fins 423 are arranged on the inserting piece portion 422, a gap exists between two adjacent heat dissipation fins 423, two ends of each heat dissipation fin 423 point to the heat dissipation through hole 411, that is, the gap formed by the heat dissipation fins 423 can be communicated with the heat dissipation through holes 411 on two sides of the protective outer cover 410, and the heat dissipation fan 430 blows air towards the inserting piece portion 422.
When the LED lamp is used, the heat dissipation part 400 is assembled according to the rule, the LED lamp wick 300 is started, the LED lamp wick 300 starts to emit light and heat, light rays are condensed by the lampshade 200 and then irradiate forwards, and heat is transferred to the inserting sheet heat dissipater 420 attached to the lampshade. The heat of the tab radiator 420 is further transferred to the heat dissipation fins 423 of the tab portion 422, and each heat dissipation fin 423 can be in sufficient contact with the air due to the gap, that is, has a large contact area with the air, so that the heat can be quickly dissipated into the air. And because the heat dissipation fan 430 blows air towards the direction of the inserting piece part 422, the air flow velocity in the gap between the heat dissipation fins 423 is increased, so that the heat exchange speed between the heat dissipation fins 423 and the air is increased, and the heated air is blown to the openings at the two ends of the gap and is discharged from the heat dissipation through hole 411, thereby realizing better heat dissipation.
It is noted that the heat dissipation member 400 of the present invention achieves dust prevention while achieving a better heat dissipation effect, and is mainly achieved by the following two aspects: on one hand, the position of the heat dissipation through hole 411 corresponds to the insert part 422 of the insert radiator 420, and even if external dust particles enter the heat dissipation through hole 411, the external dust particles are blocked by the flat plate part 421 and cannot contact with the LED lamp core 300; on the other hand, the heat dissipating fan 430 blows air toward the plug 422, and the air will be blown toward the openings at the two ends of the gap and discharged from the heat dissipating through hole 411, i.e., the air flows from inside to outside at the heat dissipating through hole 411, so that the external dust particles can be effectively prevented from entering the heat dissipating through hole 411.
In the present embodiment, as shown in fig. 7, a positioning slot 412 and a blocking piece 413 are disposed on an inner wall of the protective housing 410, the heat dissipation fan 430 is clamped in the positioning slot 412, and the heat dissipation fan 430 abuts against the blocking piece 413. When the heat dissipation device is installed, the heat dissipation fan 430 is firstly installed from the opening at one end of the protective outer cover 410, and is pushed to the edge of the heat dissipation fan 430 to sink into the positioning slot 412, and then the inserting sheet heat sink 420 is installed into the protective outer cover 410, at this time, one side of the heat dissipation fan 430 is supported by the blocking sheet 413, and the other side of the heat dissipation fan 430 is supported by the inserting sheet heat sink 420, so that the heat dissipation fan 430 cannot be separated from the protective outer cover 410.
Further, in the actual use process, it is found that an emergency lamp is often required to be placed aside during emergency, and sometimes, when the illumination direction of the emergency lamp is required to be inclined, bricks and other objects are arranged below the emergency lamp in a cushioning mode, but the mode is time-consuming and inconvenient, and the time for emergency rescue is delayed. Therefore, the emergency lamp 10 capable of dimming based on the internet of things of the invention is further provided with corresponding components for facilitating the erection or suspension of the emergency lamp, which is specifically as follows.
In the present embodiment, as shown in fig. 1, the lamp main body 100 is provided with an auxiliary supporting member 500, and the auxiliary supporting member 500 is rotatably provided on the lamp main body 100. As shown in fig. 8 and 9, the auxiliary support member 500 includes: the lamp comprises a first fixing seat 510, a second fixing seat 520, a supporting fork 530 and an adjustable limiting assembly 540, wherein the first fixing seat 510 and the second fixing seat 520 are mounted on the lamp body 100, the supporting fork 530 is provided with a first fork arm 531 and a second fork arm 532, the first fork arm 531 is rotatably arranged on the first fixing seat 510 through a torsion spring (not shown), and the second fork arm 532 is arranged on the second fixing seat 520 through the adjustable limiting assembly 540.
When not in use, the support fork 530 is attached to the outer wall of the lamp body 100; during the use, the staff will support the fork frame 530 and dial to adjust it to suitable position, like this alright with the help of supporting the fork frame 530, will realize the emergency light 10 that can adjust luminance based on the thing networking and erect suitable position (as shown in fig. 10), and through adjusting the angle of supporting the fork frame 530, alright in order to change the illumination direction based on the thing networking realizes the emergency light 10 that can adjust luminance. Of course, the support fork 530 may be used to hang an emergency light (as shown in fig. 11) in addition to being used to assist in erecting the emergency light.
Furthermore, the present invention further improves the auxiliary supporting member 500 more finely, and the following first describes a specific structure of the adjustable limiting component 540.
In this embodiment, as shown in fig. 12, the adjustable limiting component 540 includes: the sliding shaft 541 is slidably disposed on the second fixing seat 520, the end cap 543 is disposed at one end of the sliding shaft 541, the return elastic member 542 provides an elastic force for the sliding shaft 541, the friction disc 544 and the one-way limiting disc 545 are fixedly disposed on the sliding shaft 541, the second yoke 532 is rotatably connected to the sliding shaft 541, the second yoke 532 is disposed between the friction disc 544 and the one-way limiting disc 545, and the second yoke 532 is provided with a one-way staple 532a (as shown in fig. 9) engaged with the one-way limiting disc 545. The unidirectional staple 532a and the unidirectional limiting disc 545 are matched to realize unidirectional rotation of the support fork frame 530, that is, the unidirectional limiting disc 545 is used for limiting unidirectional movement of the support fork frame 530, and the friction disc 544 is used for preventing the support fork frame 530 from being reset too fast to hurt a worker, and a specific working principle will be described below.
Preferably, as shown in fig. 12, the sliding shaft 541 penetrates through the second fixing base 520, the second fixing base 520 is provided with an anti-rotation limiting nail 521, and the sliding shaft 541 is provided with a guiding limiting groove 541a matched with the anti-rotation limiting nail 521. The anti-rotation limiting nail 521 is limited in the guiding and limiting groove 541a, so that the sliding shaft 541 can only slide along the axial direction and cannot rotate relative to the second fixing seat 520.
Preferably, as shown in fig. 12, the end cap 543 is in threaded connection with the sliding shaft 541, the elastic restoring member 542 is in a spring structure, the elastic restoring member 542 is sleeved on the sliding shaft, one end of the elastic restoring member 542 abuts against the second fixing seat 520, and the other end abuts against the end cap 543. In addition, an anti-slip catch 541b is disposed at the end of the sliding shaft 541, and the anti-slip catch 541b is located between the second fixing base 520 and the outer wall of the lamp body 100, and is used for limiting a sliding range of the sliding shaft 541 and preventing the sliding shaft 541 from being separated from the second fixing base 520.
In this embodiment, the second fixing seat 520 is provided with a friction disc avoiding groove 522 (as shown in fig. 14) and a limiting disc avoiding groove 523 (as shown in fig. 13), the friction disc avoiding groove 522 and the limiting disc avoiding groove 523 are disposed opposite to each other, the friction disc 544 is accommodated in or separated from the friction disc avoiding groove 522, and the one-way limiting disc 545 is accommodated in or separated from the limiting disc avoiding groove 523. In an initial state, the friction disc 544 is accommodated in the friction disc avoiding groove 522, and the one-way limiting disc 545 is disengaged from the limiting disc avoiding groove 523 and is pressed and held on the second yoke 532; when the sliding shaft 541 is pressed, the friction disc 544 disengages from the friction disc escape slot 522 and presses against the second yoke 532, and the one-way limiter disc 545 is received in the limiter disc escape slot 523.
Preferably, as shown in fig. 9, the first fixing base 510 is provided with a rotation shaft 511, the first yoke 531 and the first fixing base 510 are disposed through the rotation shaft 511, the blocking pieces 512 are disposed at two ends of the rotation shaft 511, and the blocking pieces 512 are abutted against the first fixing base 510. The first yoke 531 is rotatably disposed on the first holder 510 about an axis of the rotation shaft 511, and a torsion spring (not shown) is disposed between the first yoke 531 and the first holder 510, and provides a restoring elastic force for the first yoke 531 (supporting the fork frame 530).
Next, the operation principle of the auxiliary supporting member 500 will be explained with reference to the above structure:
in an initial state, the support fork 530 is attached to the outer wall of the lamp body 100; when the sliding shaft 541 is not subjected to an external force, as shown in fig. 13, the return elastic member 542 is in a free state, the friction disc 544 is accommodated in the friction disc escape groove 522, the one-way stopper disk 545 is disengaged from the stopper disk escape groove 523 and is pressed against the second yoke 532, and the one-way stopper disk 545 contacts the one-way clip 532 a. Then, the worker dials the support fork 530 to rotate away from the lamp body 100 in exactly the same direction as the one-way clamp 532a, that is, the support fork 530 can be smoothly dialed. As the support fork 530 rotates, the torsion spring at the first fixing seat 510 starts to accumulate elastic force, and after the support fork 530 is shifted to a proper position, the worker removes the external force, and the torsion spring provides a tendency of returning to the support fork 530. However, at this time, the one-way limiting disc 545 is in contact with and clamped by the one-way staple 532a, and the sliding shaft 541 where the one-way limiting disc 545 is located cannot rotate, so that the support fork 530 cannot rotate to reset, and the support fork 530 is kept at the current position;
when the support fork 530 needs to be reset, a worker presses the sliding shaft 541 or the end cap 543, the sliding shaft 541 is forced to slide, as shown in fig. 14, the reset elastic member 542 is compressed, the friction disc 544 is separated from the friction disc avoiding groove 522 and is pressed on the second fork arm 532, and the one-way limiting disc 545 is accommodated in the limiting disc avoiding groove 523. At this time, the one-way limiting disc 545 and the one-way staple 532a are not clamped any more, and the support fork frame 530 starts to deflect and reset in the opposite direction under the action of the torsion spring; however, since the friction plates 544 are pressed against the second fork arms 532 at this time, the friction force generated by the friction plates 544 needs to be overcome when the support fork 530 is reset, so that the reset speed of the support fork 530 is slowed. After resetting, the supporting fork frame 530 is attached to the outer wall of the lamp body 100, the external force is removed by the operator, the sliding shaft 541 slides again under the action of the resetting elastic element 542, and the unidirectional limiting disc 545 abuts against the second fork arm 532 again, so that the supporting fork frame 530 can move only in one direction.
It can be seen that the supporting fork 530 can rotate only in one direction in the initial state and the reset speed of the supporting fork 530 can be reduced by the cooperation between the adjustable limiting assembly 540 and the supporting fork 530. The supporting fork frame 530 is not easy to be folded after being pulled out due to unidirectional rotation in the initial state, thereby ensuring that the supporting fork frame 530 can support the emergency light stably enough and improving the use reliability. And the reset speed of the supporting fork frame 530 is slowed down, so that the supporting fork frame 530 can be prevented from violently impacting the lamp body 100 due to too high speed, the supporting fork frame 530 can be prevented from being clamped by the hand of a worker due to too high reset, and the use reliability is improved.
It should be noted that the adjustable limiting component 540 can make the supporting fork frame 530 stay at any position, especially during the resetting process, if the worker suddenly removes the external force, the one-way limiting disc 545 will contact and hold the second fork arm 532 immediately, so that the supporting fork frame 530 cannot be reset continuously. That is, when the worker decreases the angle between the supporting fork 530 and the lamp body 100, the worker presses the sliding shaft 541, the supporting fork 530 starts to return, the returning speed of the supporting fork 530 is slow due to the limitation of the friction disc 544, and when the supporting fork 530 moves to a proper position, the worker removes the external force, the one-way limiting disc 545 contacts the second fork arm 532 again, and the supporting fork 530 cannot return continuously due to the action of the one-way limiting disc 545 and can only remain at the current position.
It should be emphasized that, in the initial state, as shown in fig. 13, since the reset elastic member 542 always tends to push the sliding shaft 541, the one-way limiting disc 545 can be abutted against the second prong 532, and when the second prong 532 is toggled, the inclined surface of the one-way staple 532a pushes the one-way limiting disc 545 to overcome the elastic force of the reset elastic member 542, so that the one-way limiting disc 545 can be slightly shifted and provide an escape space. When the second prong 532 wants to reset under the action of the torsion spring, the one-way limiting disc 545 abuts against the second prong 532, the one-way staple 532a and the one-way limiting disc 545 are in plane contact, the one-way staple 532a cannot provide a component force for pushing the one-way limiting disc 545 away, and thus the one-way limiting disc 545 cannot provide an avoiding space. The support fork 530 can be reset only when the worker presses the sliding shaft 541 so that the one-way clutch 545 is separated from the second fork arm 532. At the same time, the worker presses the sliding shaft 541, which also causes the friction disk 544 to abut against the second fork arm 532 (as shown in fig. 14), thereby slowing the return speed of the support fork 530.
