The housing 121 has a first end 121a1, a second end 121a2, and a passage 121a3 communicating therebetween. The circuit board 122 is disposed in the channel 121a3 and extends substantially between the first end 121a1 and the second end 121a2. The light-emitting diodes 123 are disposed on the surface 122a of the circuit board 122 (such as the bottom surface of the circuit board 122 in FIG. 4), and are sequentially arranged (for example, linearly arranged) between the first end 121a1 and the second end 121a2. Light cover The breaker 124 is located between the first end 121a1 and the light emitting diode 123. The photointerrupter 124 is configured to generate a signal when the triggering behavior is sensed. The driver 125 is disposed on the circuit board 122 (such as the top surface of the circuit board 122 in FIG. 4) and is configured to drive the light-emitting diode 123 to emit light according to the signal. The housing 121 is detachably fitted over the barrel 111 with the first end 121a1 such that the muzzle 111a is located within the cavity. When the muzzle 111a is located within the cavity, the muzzle 111a substantially faces the second end 121a2. That is, the muzzle 111a can communicate to the second end 121a2 via the passage 121a3 of the housing 121. Referring to FIG. 5 , in the present embodiment, the light emitting device 120 further includes a processor 128 . The processor 128 is configured to control the driver 125 to drive the LEDs 123 to emit light when the signals are received.

The tube body 121a has the first end 121a1, the second end 121a2, and the passage 121a3. For ease of assembly, the tube body 121a can be divided into an upper cover and a lower cover. The outer tube 121c is disposed to be sleeved outside the tube body 121a to protect the tube body 121a and the member mounted in the tube body 121a. For example, the outer tube 121c can be an aluminum tube, but the creation is not limited thereto. The front cover 121d is disposed at the second end 121a2 of the tubular body 121a and combined with the outer tubular 121c to form a complete design surface.

With the above configuration, when the light-storing bomb 200 is separated from the muzzle 111a of the barrel 111 and enters the illuminator, the light-storing bomb 200 passes through the photointerrupter 124 and the light-emitting diode 123 in the passage 121a3. At the moment when the photointerrupter 124 is blocked by the light-storing bomb 200, the light-emitting diode 123 is triggered to emit light (ie, the processor 128 controls the driver 125 to drive the light-emitting diode 123 after receiving the light-shielding signal of the photointerrupter 124. The light-storing bomb 200 sequentially illuminates the light emitted by the light-emitting diode 123 while emitting light through the light-emitting diode 123 and simultaneously emits light. Thereby, when the light-sense bomb 200 is separated from the light-emitting device 120 by the second end 121a2 of the casing 121, it can be observed very clearly in a dim environment, as if the comet-like tail is flying at a high speed.

Generally, the speed of the light-storing bomb 200 is 70 to 150 meters per second. In order to enable the light-storing bomb 200 to absorb enough light. Therefore, in some embodiments of the present invention, the light-storing bomb 200 can be continuously received for 600 microseconds, and the total length of the light-emitting diodes 123 in the housing 121 can be correspondingly 4.2 to 9 cm.

Higher (about 250~300V), and the driving voltage required for the LED 123 is lower (about 60~70V), so the charging completion time of the driver 125 is much shorter than that of the conventional flash. Therefore, the illuminating device 120 of the present invention can support Gaolian The speed of the launch (for example, at least 30 rounds per second).

In some embodiments of the present invention, the light emitting diode 123 is an ultraviolet light emitting diode. The wavelength range of the ultraviolet light emitted by it corresponds to the light-storing bomb 200, such as a green light-sense bomb. When the light-sense bomb 200 is exposed to strong ultraviolet light, it will glow green.

As shown in FIGS. 3 and 4, in the present embodiment, the light-emitting device 120 further includes a reflector 126. The reflector cup 126 is disposed in the passage 121a3 of the tubular body 121a. The light-emitting diode 123 faces the reflector 126. That is, the reflector cup 126 is placed on the opposite side of the light-emitting diode 123. The light reflecting cup 126 can reflect the light emitted by the light emitting diode 123 to the indirect light receiving surface of the light storing elastic body 200, so that the opposite sides of the light storing elastic body 200 can receive light, thereby further uniformly illuminating the light storing elastic body 200.

As shown in FIGS. 3 and 4, in the present embodiment, the light-emitting device 120 further includes a light-transmitting structural member 127. The light transmitting structure 127 is disposed between the light emitting diode 123 and the reflective cup 126. The light transmissive structure 127 and the reflector 126 together form a guiding conduit (i.e., one or all of the channels 121a3). Both ends of the guiding duct face the first end 121a1 and the second end 121a2, respectively. By providing the light-transmitting structure member 127 between the light-emitting diode 123 and the reflector cup 126, the light emitted by the light-emitting diode 123 can reach the reflector cup 126 through the light-transmitting structure member 127, and the light-transmitting structure member 127 Forming the guiding duct together with the reflector cup 126 also prevents the light-storing bomb 200 from colliding with other components inside the light-emitting device 120 when passing through the tubular body 121a to cause damage.

In some embodiments of the present creation, the guide conduit has a central axis C. In the direction perpendicular to the central axis C, the photointerrupter 124 is substantially aligned The one of the photodiodes 123 that is closest to the first end 121a1.

As shown in FIG. 3 and FIG. 4 , in the present embodiment, the tubular body 121 a of the housing 121 further includes a battery slot 121 a 4 , which is disposed on both sides of the reflector 126 and is configured to receive a battery (eg, alkaline). battery). The illuminating device 120 further includes a conductive terminal 129 disposed in the housing 121 and configured to electrically connect the circuit board 122 and the battery to transmit power of the battery to the circuit board 122.

As shown in FIGS. 2 to 4, in the present embodiment, the circuit board 122 of the light-emitting device 120 further includes a switch 122b and a button 122c. The button 122c is configured to press the switch 122b in a direction (e.g., by structure within the housing 121) and is partially exposed outside of the housing 121 to selectively turn the light emitting device 120 on or off. In some embodiments of the present invention, the switch 122b may further include a light source 122b1 for indicating the opening and closing state of the light emitting device 120, and the button 122c may be a light guiding column, thereby guiding the opening and closing state displayed by the light source 122b1. It is outside the housing 121 for the user to clearly see.

More power saving. The illuminating device of the present invention has a plurality of illuminating diodes arranged in sequence (arranged along the trajectory direction), and a photointerrupter is disposed at a position before the illuminating bomb passes through the illuminating diode. When the light-sense bomb passes through the illuminator through the illuminator, the moment when the photo-interrupter is blocked by the light-storing bomb, the illuminating diode will be triggered to emit light, and the light-storing bomb will emit the light-emitting diode during the passage of the light-emitting diode. The light is stored and illuminated at the same time. It can be seen from the light-emitting characteristics of the light-emitting diode that the flicker frequency can be very high, and thus the light-emitting device of the present invention can support the high-speed emission rate. In addition, this creation The illuminating device also places a reflector on the opposite side of the illuminating diode, which can reflect the light to the non-direct light receiving surface of the illuminating bomb, so that the opposite sides of the illuminating bomb can receive light, so that the illuminating bomb can uniformly emit light.
