The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.

The present invention provides a flashlight 10 suitable for outdoor illumination, as shown in fig. 1 and 2, comprising: the light emitting device comprises a cylinder 100, a light emitting member 200, a power supply member 300, and a base member 400, wherein the base member 400 is mounted on the cylinder 100, the light emitting member 200 is provided in the cylinder 100, and the light emitting member 200 is located between the cylinder 100 and the base member 400.

As shown in fig. 3, the light emitting component 200 includes an LED lamp bead 210 and a heat dissipation auxiliary member 220 in contact with the LED lamp bead 210.

As shown in fig. 2 and 3, the base member 400 includes: the LED lamp comprises an outer cover body 410, a light reflecting cup 420 and a protection component 430, wherein the outer cover body 410 is in threaded connection with the cylinder body 100, the light reflecting cup 420 and the protection component 430 are arranged in the outer cover body 410, the LED lamp beads 210 are located on one side of the light reflecting cup 420, and the protection component 430 is located on the other side of the light reflecting cup 420. The primary purpose of the protective assembly 430 is to provide better dust and water resistance to the flashlight 10, while enhancing the shatter resistance of the flashlight 10.

In this embodiment, as shown in fig. 2 and 3, the protection component 430 includes: the light transmitting member 431, the first sealing ring 432, the second sealing ring 433 and the front protection member 434, wherein the light transmitting member 431 is located at one side of the light reflecting cup 420, the first sealing ring 432 is arranged between the light transmitting member 431 and the outer cover body 410, the second sealing ring 433 is arranged between the light transmitting member 431 and the light reflecting cup 420, the front protection member 434 is arranged at the end part of the outer cover body 410, and the front protection member 434 is pressed on the light transmitting member 431.

In contrast to the prior art, the protective assembly 430 of the present invention has a first seal ring 432 and a second seal ring 433. The first sealing ring 432 is disposed between the light-transmitting member 431 and the housing body 410, that is, the first sealing ring 432 is sleeved on the outer sidewall of the light-transmitting member 431, so that the gap between the light-transmitting member 431 and the housing body 410 is filled with the first sealing ring 432. Meanwhile, the second sealing ring 433 is disposed between the light transmitting member 431 and the light reflecting cup 420, and the second sealing ring 433 is also abutted against the inner wall of the housing body 410. Thus, the first seal ring 432 and the second seal ring 433 cooperate to provide the following benefits to the protection assembly 430:

firstly, the arrangement of the double sealing rings makes up the gaps among the parts better, thereby preventing dust and water vapor from entering the flashlight 10 better;

secondly, due to the arrangement of the double sealing rings, the light-transmitting part 431 is allowed to have larger tolerance, so that the processing precision requirement of the light-transmitting part 431 is reduced;

third, the first sealing ring 432 is sleeved on the outer circular side wall of the light-transmitting member 431, so that when the flashlight 10 is knocked, the first sealing ring 432 can provide buffering for the light-transmitting member 431, thereby protecting the fragile light-transmitting member 431; similarly, the second sealing ring 433 is disposed between the light-transmitting member 431 and the light-reflecting cup 420, and when the flashlight 10 is bumped, the second sealing ring 433 provides buffering for the light-transmitting member 431 and the light-reflecting cup 420, so as to protect the flashlight.

In this embodiment, as shown in fig. 3, the front guard 434 is in threaded engagement with the housing body 410, and the front guard 434 is provided with a wave structure 434a and a turned edge 434b, and the turned edge 434b abuts against the edge of the housing body 410.

When the front guard 434 is impacted, the front guard 434 transmits most impact force to the housing body 410 through the turnup edge 434b and the screw structure, so that the fragile parts in the housing body 410 are protected from impact. Only a very small amount of impact force is transmitted to the light transmitting member 431, and the light transmitting member 431 is not affected by the impact force due to the buffering action of the second sealing ring 433. Thus, flashlight 10 may be used as a life hammer if desired; furthermore, the front guard 434 is provided with a wave structure 434a so that the flashlight 10 can more easily break obstacles when being hammered.

Further, in another embodiment, as shown in fig. 4 and 5, a detachable lamp holder 230 is provided between the barrel 100 and the light emitting member 200, and the lamp holder 230 is used to connect the barrel 100 and the light emitting member 200. The heat dissipation auxiliary member 220 is an aluminum-based plate structure; the LED lamp beads 210 are attached to the lamp base 230 through the heat dissipation auxiliary member 220. The power supply part 300 includes a control board 310 (as shown in fig. 7), and the control board 310 and the LED lamp beads 210 are electrically connected through wires 311, and the wires 311 are inserted into the lamp holder 230 (the wires 311 include a positive wire and a negative wire).

Compared with the prior art, the flashlight 10 of the present embodiment is additionally provided with the heat dissipation auxiliary member 220, and the heat dissipation auxiliary member 220 is of an aluminum-based plate structure. When in use, the LED lamp beads 210 generate light and heat, and the heat is transferred to the heat dissipation auxiliary piece 220, so that the heat dissipation area is increased; the heat dissipation auxiliary member 220 further transfers heat to the lamp holder 230 and the barrel 100, thereby further accelerating heat dissipation, so that the flashlight 10 has good heat dissipation effect, and the service life of the flashlight 10 is prolonged. And the aluminum substrate structure is adopted, so that the heat conduction performance is considered, and meanwhile, the production cost is reduced.

Compared with the prior art, the flashlight 10 of the present embodiment is further provided with a detachable lamp holder 230. The conventional lamp socket 230 is generally integrally formed with the can 100 and performs a surface oxidation treatment on the workpiece after production, so that the can portion of the workpiece is more durable. However, an oxide film exists on the lamp socket portion of the surface-treated workpiece, which makes the contact heat dissipation efficiency (thermal conductivity) of the LED lamp beads 210 not high, and thus is unfavorable for the heat dissipation of the LED lamp beads 210. The lamp holder 230 of the present invention is detachably arranged, so that the cylinder 100 and the lamp holder 230 can be simultaneously processed during the production and processing, thereby shortening the processing time and facilitating the installation of the light emitting component 200 on the lamp holder 230; meanwhile, the cylinder 100 may be surface-treated alone, and the lamp holder 230 may not be surface-treated, so that durability of the cylinder 100 may be considered and good contact heat dissipation efficiency of the lamp holder 230 may be maintained.

It is emphasized that in the present embodiment, the lamp holder 230 and the cylinder 100 are connected by screw threads, so that the lamp holder 230 and the cylinder 100 can be stably connected, and the contact area between the lamp holder 230 and the cylinder 100 can be increased, so that the heat conducting capability between the lamp holder 230 and the cylinder 100 is enhanced, and the heat of the lamp holder 230 can be dissipated through the cylinder 100 more quickly.

However, when the lamp socket 230 is screw-coupled, the following new technical problems occur: the control board 310 is mounted in the cylinder 100 before the lamp holder 230, and as shown in fig. 6, the wires 311 (positive and negative wires) need to pass through the lamp holder 230 to electrically connect the control board 310 with the LED lamp beads 210, and after the wires 311 pass through the lamp holder 230, the lamp holder 230 is spirally connected with the cylinder 100, so that the wires 311 rotate together with the lamp holder 230, and thus the positive and negative wires are easily wound and knotted. Therefore, the structure of the lamp holder 230 is further improved to overcome the problem of winding and knotting of the wires 311.

Specifically, as shown in fig. 7, a waist-shaped avoidance through groove 231 is formed in the lamp holder 230, and the conductive wire 311 is inserted into the waist-shaped avoidance through groove 231 (the conductive wire 311 includes a positive conductive wire and a negative conductive wire). During installation, the staff first concentrates the positive electrode lead and the negative electrode lead in the middle of the waist-shaped avoiding through groove 231, and then spirally connects the lamp holder 230 and the cylinder body 100, so that the lead 311 cannot rotate along with the lamp holder 230 in the spiral process, and the positive electrode lead and the negative electrode lead cannot be wound together. After the lamp holder 230 is twisted, the staff disposes the positive and negative wires on two sides of the waist-shaped avoiding through groove 231 respectively, and finally electrically connects the positive and negative wires with the LED lamp beads 210 respectively.

It should be noted that, after such design, the heat dissipation auxiliary member 220 still keeps in contact with the inner wall of the lamp socket 230, and the heat of the heat dissipation auxiliary member 220 can still be transferred to the lamp socket 230 through the contact surface, so that the heat dissipation of the light emitting component 200 is not substantially affected. Meanwhile, the wire 311 is conveniently penetrated through the lamp holder 230, and the wire 311 winding phenomenon caused by the screw of the lamp holder 230 is avoided.

Furthermore, the flashlight 10 of the present invention has a power display function, so that a user can observe the power condition of the battery built in the flashlight 10 at any time.

Specifically, as shown in fig. 7, the control board 310 is provided with a plurality of power indicator lamps 312 and a switch button 313. The power supply part 300 includes a built-in battery 320 and a key display assembly 330, and the built-in battery 320 supplies power to the control board 310 and the LED lamp beads 210.

As shown in fig. 8 and 9, the key display assembly 330 includes: a spectroscopic key frame 331, a key lever 332, and a key guide cap 333. The light splitting key frame 331 is mounted on the control board 310, and a light channel 331a matched with the electric quantity indicator lamp 312 is formed in the light splitting key frame 331; the key rod 332 is abutted against the switch button 313, and the key rod 332 is slidably arranged on the light splitting key frame 331; the key guide cap 333 is located between the spectroscopic key frame 331 and the cylinder 100.

Preferably, as shown in fig. 9, 10 and 11, the number of the power indicator lamps 312 is plural, the number of the light channels 331a is the same as the number of the power indicator lamps 312, and each light channel 331a corresponds to one power indicator lamp 312. The key guide cap 333 is provided with light guide columns 333a, the number of the light guide columns 333a is the same as that of the electric quantity indicator lamps 312, and the light guide columns 333a penetrate through the cylinder 100.

In operation, the control board 310 monitors the remaining power of the built-in battery 320 and displays it through the power indicator 312 (e.g., 0-25% for 1 lamp, 25-50% for 2 lamps, 50-75% for 3 lamps, 75-100% for 4 lamps). The light emitted by each electric quantity indicating lamp 312 passes through the light channel 331a of the corresponding light splitting key frame 331 and irradiates onto the corresponding light guide column 333a (as shown in fig. 10), and the light is refracted in the light guide column 333a for multiple times, so that the corresponding light guide column 333a is illuminated, and then the user can judge the residual electric quantity of the built-in battery 320 by observing the number of the light emitting light guide columns 333 a.

Note that, the key guide cap 333 is mainly designed to be dustproof and waterproof. Because flashlight 10 is intended to be used outdoors, barrel 100 needs to achieve a good seal at the key portion. By providing the key duct cap 333, the edge of the key duct cap 333 abuts against the inner wall of the cylinder 100 (as shown in fig. 10), so that external dust or moisture can be prevented from entering the cylinder 100.

The design of the light splitting key frame 331 has two functions: on the one hand, the light-splitting key frame 331 provides support for the key guide cap 333 and also limits the sliding of the key lever 332, so that the key lever 332 can be accurately pressed onto the switch button 313; on the other hand, the light channel 331a of the light splitting key frame 331 separates the light emitted by each of the electric quantity indicator lamps 312, so as to prevent the electric quantity indicator lamps 312 from being irradiated onto the non-corresponding light guide columns 333 a.

In one embodiment, as shown in fig. 9 and 10, a charging interface 340 is provided on the control board 310, a detachable safety helmet 110 is provided on the barrel 100, and the safety helmet 110 is covered at the charging interface 340. The charging interface 340 is electrically connected with the control board 310, and the safety helmet 110 is arranged to enable the charging interface 340 to have dustproof and waterproof functions.

In summary, the flashlight 10 suitable for outdoor illumination of the present invention has good sealing performance and anti-falling performance, and simultaneously has a good heat dissipation structure, so as to meet the requirement of outdoor exploration.

The above examples illustrate only a few embodiments of the invention, which are described in detail and are not to be construed as limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention. Accordingly, the scope of protection of the present invention is to be determined by the appended claims.
