Those skilled in the art may understand the specific meanings of the above terms in the present invention according to specific circumstances.

[0023] As shown in Figures 1 to 4, a fluorescent emergency light source device according to an embodiment of the first aspect of the present invention includes a light-emitting module 100 and a jacket unit 400, the light-emitting module 100 includes a lamp plate 200 and an LED unit 300 installed on the lamp plate 200, the jacket unit 400 covers the outer surface of the light-emitting module 100, and the jacket unit 400 includes a light-transmitting portion 410 and a fluorescent portion 420, the light-transmitting portion 410 is located in front of the LED unit 300, and the fluorescent portion 420 is located to the side of the LED unit 300, and the fluorescent portion 420 can absorb light and form afterglow.

[0024] Here, in some embodiments of the present invention, the jacket unit 400 is made of an insulating material, and the jacket unit 400 covers the light emitting module 100, thereby preventing dust and mist from corroding the light emitting module 100, and preventing the light emitting module 100 from coming into contact with external objects and causing a short circuit.

[0025] In some embodiments of the present invention, the lamp plate 200 may be circular, rectangular, or elongated, and may be made of a hard material such as ceramics or aluminum alloy, and the jacket unit 400 may be made of an acrylic or glass material. The lamp plate 200 may be a flexible film circuit board, and the jacket unit 400 may be made of a flexible rubber, silica gel, PVC, or resin material accordingly.

[0026] The fluorescent portion 420 may be integrally formed with the light-transmitting portion 410. The fluorescent portion 420 may be formed by mixing a fluorescent material into the jacket unit 400. For example, if the jacket unit 400 is made of rubber, the fluorescent material may be added and uniformly mixed into the rubber when the rubber is in a molten state, and then the rubber solidifies to form the fluorescent portion 420, where the fluorescent material may be fluorescein isothiocyanate, tetraethylrhodamine, etc.

[0027] In the fluorescent emergency light source device of the present invention, a transparent portion 410 is installed in front of the LED unit 300. When the LED unit 300 is powered on, the LED unit 300 emits light. Most of the light is emitted directly from the transparent portion 410 to the outside, while a portion of the light is irradiated onto the fluorescent portion 420 on the side. The light is absorbed by the fluorescent material in the fluorescent portion 420. When the LED unit 300 turns off, the fluorescent portion 420 generates an afterglow, thereby providing supplemental lighting or indication. Because the fluorescent portion 420 is located on the side of the LED unit 300, when the LED unit 300 is emitting light normally, the fluorescent portion 420 does not interfere with the normal illumination of the LED unit 300. This design meets basic lighting needs and can provide supplemental fluorescent lighting in the event of a malfunction. It is easy to use and reliable.

[0028] In some embodiments of the present invention, as shown in FIG. 3 , the fluorescent emergency light source device may be single-sided, in which the LED unit 300 is installed on one surface of the lamp plate 200, the translucent portion 410 is located directly above the LED unit 300, and the fluorescent portion 420 is located on both sides of the LED unit 300 or around the LED unit 300.

[0029] In some embodiments of the present invention, as shown in FIG. 4, the fluorescent emergency light source device may be double-sided, and the LED unit 300 includes a first LED light group 310 and a second LED light group 320, the first LED light group 310 is installed on the upper surface of the lamp plate 200, the second LED light group 320 is installed on the lower surface of the lamp plate 200, and there are two light-transmitting portions 410, which are located in front of the first LED light group 310 and the second LED light group 320, respectively.

[0030] The first LED light group 310 and the second LED light group 320 may be respectively installed on the upper and lower surfaces of the lamp plate 200. Accordingly, two light-transmitting portions 410 are also installed, facing the first LED light group 310 and the second LED light group 320, respectively. Either the first LED light group 310 or the second LED light group 320 may be turned on to emit light, or the first LED light group 310 and the second LED light group 320 may emit light simultaneously. Most of the light rays are emitted from the light-transmitting portions 410 in the same manner, and some of the light rays are absorbed by the fluorescent portion 420. After the first LED light group 310 and the second LED light group 320 are turned off, the fluorescent portion 420 emits fluorescence.

[0031] In some embodiments of the present invention, the transparent portion 410 has a cup shape, and the width of the cross section of the transparent portion 410 gradually increases along the light emission direction. Due to the difference in optical medium coefficient between the transparent portion 410 and the fluorescent portion 420, the light entering the transparent portion 410 is reflected at the boundary between the transparent portion 410 and the fluorescent portion 420, and the contour of the cup-shaped transparent portion 410 can adjust the incident angle of the light, which is more advantageous for light convergence and light emission.

[0032] In some embodiments of the present invention, as shown in Figures 1, 3, and 4, the lamp plate 200 has an elongated shape, the LED unit 300 includes a plurality of LED wicks 330 arranged along the longitudinal direction of the lamp plate 200, and the fluorescent units 420 are located on both sides of the longitudinal direction of the lamp plate 200, thereby making it possible to apply the lamp plate 200 to a wider range of applications. The fluorescent emergency light source device may be arranged in a location extending along the longitudinal direction, emitting light along a line, and after the LED unit 300 is turned off, the fluorescent units 420 on both sides can assist in emitting light along the line.

[0033] In some embodiments of the present invention, as shown in Figures 3 and 4, the translucent portion 410 is elongated and arranged along the longitudinal direction of the lamp plate 200, and the width of the cross section perpendicular to the extension direction of the translucent portion 410 gradually increases.

[0034] Similarly, the width of the cross section perpendicular to the elongation direction of the transparent portion 410 gradually increases. Due to the difference in optical medium coefficient between the transparent portion 410 and the fluorescent portion 420, the light entering the transparent portion 410 is reflected at the boundary between the transparent portion 410 and the fluorescent portion 420, and the width of the cross section perpendicular to the elongation direction of the transparent portion 410 gradually increases, i.e., the transparent portion 410 has a cup shape. The angle of incidence of the light can be adjusted by the contour of the cup-shaped transparent portion 410, which is more advantageous for light convergence and light emission.

[0035] In some embodiments of the present invention, as shown in FIG. 2 , the light emitting module 100 further includes a rectifier module 340 and an electrical connection terminal group 350, the rectifier module 340 and the electrical connection terminal group 350 are installed on the lamp plate 200, the AC input terminal of the rectifier module 340 is connected to the electrical connection terminal group 350, and the DC output terminal of the rectifier module 340 is connected to the LED unit 300.

[0036] The rectifier module 340 may be a rectifier chip or a rectifier circuit composed of multiple discrete diodes, and may be installed on the lamp plate 200. The electrical connection terminal group 350 may be a pad, connection terminal, conductive elastic sheet, etc. installed on the lamp plate 200. The electrical connection terminal group 350 allows the fluorescent emergency light source device to be directly connected to a commercial power source, and the rectifier module 340 rectifies AC power to DC power before supplying it to the LED unit 300, making it easy to connect and use.

[0037] In some embodiments of the present invention, as shown in FIG. 2 , the LED unit 300 includes at least one LED string light, which includes a plurality of LED wicks 330 and a current limiting element 360, the plurality of LED wicks 330 and the current limiting element 360 are connected in series with each other, and the LED string light is connected to the DC output terminal of the rectifier module 340.

[0038] When directly connected to a commercial power source, fluctuations in the commercial power source voltage exist, and if the voltage is too high, the current will increase, thereby damaging the LED wick 330. Therefore, when the current is too high, the current limiting element 360 generates a relatively high resistance, thereby limiting the series current in the LED string light. Specifically, the current limiting element 360 may be a current limiting chip.

[0039] In some embodiments of the present invention, the LED string light further includes a current-limiting resistor 370, which is connected in series with the LED wick 330 and the current-limiting member 360. Based on the output voltage of the rectifier module 340, the current-limiting resistor 370 can select an appropriate resistance value according to the number and resistance value of the LED wicks 330, thereby determining the current of the LED string light and ensuring stable operation of each LED wick 330.

[0040] In some embodiments of the present invention, as shown in FIG. 2 , the light emitting module 100 further includes a first busbar 380 and a second busbar 390 installed on the lamp plate 200, and the DC output terminal of the rectifier module 340 is connected to the first busbar 380 and the second busbar 390 respectively. There are multiple LED string lights, and one end of each of the LED string lights is connected to the first busbar 380 and the other end of each of the LED string lights is connected to the second busbar 390.

[0041] Each LED string light is arranged along the longitudinal direction of the lamp plate 200, and a first bus bar 380 and a second bus bar 390 are installed on the lamp plate 200 and extend along the longitudinal direction of the lamp plate 200, thereby supplying electricity to each LED string light, and the power supply voltage of the LED string light is the voltage between the first bus bar 380 and the second bus bar 390. Specifically, the first bus bar 380 may be a positive bus bar and is connected to the positive pole of the DC output terminal of the rectifier module 340, and the second bus bar 390 may be a negative bus bar and is connected to the negative pole of the DC output terminal of the rectifier module 340.

[0042] As described above, the technical features of the embodiments may be combined in any manner. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, all of them fall within the scope of the present specification.

[0043] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is limited only by the claims and their equivalents.
