When the explosion-proof flashlight 10 is turned on or off, the hard key 43 at the tail part is pressed for a long time, the light source of the indicator light can flash, the number of times of flashing is the current electric quantity of the lamp, for example, four times of flashing is full electricity, three times of flashing is for representing 75% of the residual electric quantity, two times of flashing is for representing 50% of the residual electric quantity, and one time of flashing is for representing 25% of the residual electric quantity, and the explosion-proof flashlight 10 is required to be charged in time (of course, the indicator light is not required to be arranged, and the indication effect can be directly achieved through flashing of the lamp cap component 1). And when the explosion-proof flashlight 10 is lighted, the indicator lamp can also be lighted at the same time for the working state of the surface explosion-proof flashlight 10.
In some embodiments, referring to fig. 1 to 9, the explosion-proof flashlight 10 may further include a back clip 7 disposed on a side surface of the main body 2 of the barrel, where one end of the back clip 7 may be fixed by a fastener such as a screw or a bolt, so as to facilitate the user to carry the explosion-proof flashlight 10. In other embodiments, the explosion-proof flashlight 10 may further include brooches, caps, ropes or magnetic chest rings, etc. disposed on the side of the main body 2 of the barrel, so as to facilitate the user to carry the explosion-proof flashlight 10.
In some embodiments, referring to fig. 1 to 11, the anti-explosion lighting device 100 may further include a fixing base 20, and since the anti-explosion flashlight 10 is often applied to environments such as mines, the fixing base 20 can well fix the anti-explosion flashlight 10, so as to prevent the anti-explosion flashlight 10 from rolling or even falling, and causing explosion due to electric spark.
Optionally, the fixing base 20 may include a base 21 and a snap ring 22, one end of the snap ring 22 is connected to the base 21, and the other end of the snap ring is provided with a clamping groove for the anti-explosion flashlight 10 to be clamped, so that the anti-explosion flashlight 10 is clamped in the clamping groove, and the anti-explosion flashlight 10 can be fixed.
Optionally, a fastening structure 23 may be disposed between the snap ring 22 and the explosion-proof flashlight 10, so as to improve the fastening firmness and position the explosion-proof flashlight 10. Specifically, the fastening structure 23 may be an adaptive fastening and fastening slot.
Optionally, the vertical section (the section along the direction from the base to the snap ring) of the snap ring 22 may be C-shaped, that is, the snap ring 22 is integrally annular and has an opening penetrating through the side wall of the annular, so that the snap ring 22 may well wrap the anti-explosion flashlight 10 on the basis of conveniently placing the anti-explosion flashlight 10 into the snap ring 22 from the opening, thereby further improving the fixing effect.
Optionally, a reinforcing rib 24 may be disposed at the connection between the snap ring 22 and the base 21 and on the surface of the base 21, so as to strengthen the strength between the snap ring 22 and the base 21 and improve the service life of the fixing seat 20.
In practical application, the temperature of the environment where the explosion-proof flashlight 10 is used can be minus 40 ℃ which is less than or equal to Ta which is less than or equal to +55 ℃, and the protection grade can be IP66 and IP67 (1 m,30 min).
In the specific application, snap ring 22 can include two clamping pieces that are arcuation and set up relatively to fixing base 20 can be equipped with adjusting device, and adjusting device can adjust the distance between two clamping pieces, thereby can adjust the size of the draw-in groove of snap ring 22, during the use, can make two clamping pieces keep away from each other earlier, make things convenient for explosion-proof flashlight 10 card to go into, then can make two clamping pieces be close to each other, improves fixed firmness, can also adapt to the flashlight of equidimension like this, improves fixing base 20's suitability.
In a specific application, the snap ring 22 may be rotatably connected to the base 21 by a rotating device, so that the explosion-proof flashlight 10 can emit light at a certain angle when the explosion-proof flashlight 10 is fixed. The base 21 may further be provided with a magnetic device, a vacuum adsorption device, or a bonding device, for facilitating the connection of the fixing base 20 to each working surface such as a column or a table top.
In a specific application, the explosion-proof flashlight 10 may further include a detector and an alarm, where the detector may be used to detect the temperature and the air pressure in the explosion-proof flashlight 10, and when the temperature and the air pressure in the explosion-proof flashlight 10 do not meet the preset range, the alarm may directly send an alarm or send an alarm signal to the driving component 3, so that the explosion-proof flashlight 10 may send an alarm indication light (such as continuously flashing red light).
According to the invention, the LED chip 12 is welded on the light source plate 11, the lamp cap part 1 is connected with the battery of the driving part 3 through the positive elastic piece 13 and the negative elastic piece 14, the driving assembly 32 of the driving part 3 comprises a driving plate, a connecting elastic piece and a charging elastic piece 321, one end of the connecting elastic piece is connected with the driving plate, the other end of the connecting elastic piece is connected with one end of the charging elastic piece 321, and the other end of the charging elastic piece 321 extends out of the barrel body 2 or the tail cover part 4 for realizing driving charging.
