Description

Technical Field

[0001] The utility model belongs to the technical field of police equipment, and particularly relates to an adaptive strong light dazzler. Background Art

[0002] Dazzlers, a type of non-lethal weapon, are favored by police or troops in various countries for their special efficacy, mainly including two categories: laser dazzlers and strong light dazzlers.

[0003] A laser dazzler irradiates the human eye with a certain power of laser. Without causing permanent damage to the opponent's eyes, it can cause the opponent to be unable to observe, thereby achieving the purpose of stopping the opponent from advancing or making them lose their attack ability. In 2008, Professor Li Hongchang of the Armed Police Engineering College developed the first domestic vehicle-mounted non-lethal laser dazzler weapon, installing the laser dazzler disclosed in the patent CN204788041U on a military vehicle. The spot diameter of this weapon can reach 13m at a distance of 500m, providing a new option for handling emergencies at medium and long distances.

[0004] It should be noted that although a laser dazzler is not lethal, it may cause visual organ disorders, resulting in enemy dazzle blindness, flash blindness, and even permanent eye damage.

[0005] The utility model patent CN215373717U discloses a folding shield with a strong light dazzling function. It mainly includes a main shield, a first side shield, and a second side shield. Torsion springs and rotating shafts are provided at the joints between the first side shield and the second side shield and the main shield respectively. At the upper end of the rear surface of the main shield, a pressing card is provided, and at the lower end of the main shield located below the pressing card, a buckle is connected. On one side of the upper end of the front surface of the main shield, a strong light irradiation hole is provided, and a strong light dazzler is installed on the rear surface of the main shield corresponding to the strong light irradiation hole. A buffer pad is installed on the rear surface of the main shield, and a handle is installed at the upper end of the surface of the buffer pad. This shield can be folded or unfolded for use according to tactical needs. Moreover, during use, it can be quickly unfolded. The unfolded state can increase the defense area by nearly twice, and at the same time, it can suddenly attack the gangsters with strong light, thereby achieving the purpose of quickly subduing them. In the folded state, it is convenient to carry and also has normal defense and combat capabilities. However, it should be noted that due to the complexity of the structure and the diversity of functions, it is not suitable for the needs of front-line police officers to quickly handle emergencies.

[0006] Design Patent CN303299811S discloses a strong light dazzler of model SYSD-11B. Judging from its appearance, this patent is similar to a large-sized flashlight, with a switch at the tail and a switch at the front. It is a non-lethal optical device used for special situations such as searching at night (or in dark places) and handling emergency events. It emits a strong strobe light to dazzle people and temporarily lose their attack ability. It can also be used as a lighting device during search and rescue in a night (or dark) environment. It should be noted that the design appearance lacks tacticity.

[0007] Therefore, according to the actual combat needs of front-line police officers, there is an urgent need for a one-key strong light dazzler that is suitable for different lighting environments and different close distances.

[0008] Currently, the strong light dazzlers on the market cannot sense the ambient light illumination of the external environment, nor can they change the illumination intensity of the light hitting the target according to the distance from the target. In an external environment with sufficient sunlight, the strong light emitted by the dazzler may not have an effective dazzling effect on the target. When the distance from the target person is relatively far, the strong light emitted by the dazzler may not have an effective dazzling effect on the target, or when it is too close to the target person, the illumination intensity of the light emitted by the dazzler is too large, which may instead cause certain damage to the eyes of the target person, resulting in some situations with poor usage effects.

[0009] Therefore, in order to solve the above problems, it is necessary to design an adaptive strong light dazzler. Utility Model Content

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. Usually, the components of the embodiments of the present utility model described and illustrated herein can be arranged and designed in various different configurations.

[0030] Therefore, the following detailed description of the embodiments of the present utility model provided in the drawings is not intended to limit the scope of the claimed present utility model, but merely represents the selected embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the scope of protection of the present utility model.

[0031] It should be noted that: similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0032] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the product of the present utility model is usually placed during use. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be construed as a limitation to the present utility model. In addition, terms such as "first", "second", "third", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0033] In addition, terms such as "horizontal" and "vertical" do not mean that the components are required to be absolutely horizontal or hanging vertically, but can be slightly inclined. For example, "horizontal" only means that its direction is more horizontal relative to "vertical", and does not mean that the structure must be completely horizontal, but can be slightly inclined.

[0034] In the description of the present utility model, it should also be noted that unless otherwise clearly specified and defined, the terms "set", "installed", "connected", "connected to" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0035] For this reason, the following solutions are proposed:

[0036] See Figure 1 , the present utility model provides a new type of adaptive strong light dazzle device, including a power supply 10 and a duty switch 20. The power supply 10 and the duty switch 20 are respectively connected to a continuous light system (not shown in the figure) and a strong light irradiance adaptive control system 100. In the circuit loop of the power supply 10 and the duty switch 20 and the continuous light system, the duty switch 20 controls the opening and closing of the continuous light system, and at this time it is the "continuous light" operation mode.

[0037] In the circuit loop of the power supply 10 and the duty switch 20 and the strong light irradiance adaptive control system 100, as Figure 1As shown, the high-intensity light irradiance adaptive control system 100 includes an ambient brightness sensing module 30, a glare switch 40, a light source power control unit 50, and a light source emitter 60 that are connected in sequence by circuits. Among them, the input end of the ambient brightness sensing module 30 is connected to an output end of the duty switch 20. When the duty switch 20 is in the on state, it not only makes the adaptive high-intensity light glare eliminator of the present invention be in the "continuous light" operation mode, but also makes the high-intensity light irradiance adaptive control system 100 be in a standby state at any time. The duty personnel trigger the circuit connection of the high-intensity light irradiance adaptive control system 100 by manually pressing the glare switch 40 mechanically to turn on the "high-intensity light glare" operation mode.

[0038] In the high-intensity light irradiance adaptive control system 100 of the present invention, the ambient brightness sensing module 30 is used to sense the brightness of the external environment and is signal-connected to the light source power control unit 50 to transmit the information of the ambient brightness of the surrounding environment obtained by the ambient brightness sensing module 30 to the light source power control unit 50. The light source power control unit 50 adjusts the high-intensity light irradiance emitted by the light source emitter 60 in real time according to the obtained ambient brightness information.

[0039] In some embodiments, the ambient brightness sensing module 30 senses the light intensity of the external environment, and the ambient brightness sensing module 30 transmits the light intensity information of the external environment to the light source power control unit 50 in real time. The light source power control unit 50 adjusts the light effect emitted by the light source emitter 60 in real time according to the light intensity information of the external environment transmitted by the ambient brightness sensing module 30. For example, when the light source power control unit 50 senses through the ambient brightness sensing module 30 that the light intensity of the external environment is strong, the light source power control unit 50 adjusts the light intensity emitted by the light source emitter 60 to be smaller in real time, that is, emits weaker light; or when the light source power control unit 50 senses through the ambient brightness sensing module 30 that the light intensity of the external environment is weak, the light source power control unit 50 adjusts the light intensity emitted by the light source emitter 60 to be larger in real time, that is, stronger light.

[0040] The specific composition of the ambient brightness sensing module 30 is not limited here and can be determined according to actual needs. For example, it can be composed of a photoresistor sensor module, but it is not limited to this.

[0041] In an embodiment of the adaptive strong light dazzle device provided by the present utility model, the ambient light intensity sensing module 30 is connected to the circuit input end of the dazzle switch 40, and one circuit output end of the dazzle switch 40 is connected to the light source power control unit 50. In another embodiment, another circuit output end of the dazzle switch 40 of the adaptive strong light dazzle device provided by the present utility model is further connected to the laser ranging module 70 circuit, and the laser ranging module 70 is signal-connected to the light source power control unit 50 to transmit the information of the distance to the target person obtained by the laser ranging module 70 to the light source power control unit 50, and the light source power control unit 50 adjusts the strong light irradiance emitted by the light source emitter 60 in real time according to the obtained information of the distance to the target person.

[0042] Here, the specific composition of the light source power control unit 50 is not limited and can be determined according to actual needs. For example, it can be composed of an MCU chip and a constant current drive control chip FS5259. Among them, the MCU chip is data-connected to the laser ranging module 70 and the ambient light intensity sensing module 30, and is also connected to the constant current drive control chip FS5259, while the constant current drive control chip FS5259 is control-connected to the light source emitter 60.

[0043] In some embodiments, the distance to the target person is sensed by the laser ranging module 70, and the laser ranging module 70 transmits the distance information of the target person to the light source power control unit 50 in real time. The light source power control unit 50 adjusts the lighting effect emitted by the light source emitter 60 in real time according to the distance information of the target person transmitted by the laser ranging module 70. For example, when the laser ranging module 70 senses that the distance to the target person is within (1m - 10m), the light source power control unit 50 adjusts the light source emitter 60 to emit strong light with a relatively large lighting intensity in real time; or when the laser ranging module 70 senses that the distance to the target person is less than 1 meter, the light source power control unit 50 adjusts the light source emitter 60 to emit light with a relatively small lighting intensity in real time.

[0044] Here, the specific composition of the laser ranging module 70 is not limited and can be determined according to actual needs. For example, it can be composed of an existing stable and reliable laser ranging chip.

[0045] As an embodiment of the present utility model, the light source emitter 60 includes a dazzle lamp group, which uses a white LED light source. The number of dazzle lamp beads can be appropriately adjusted according to the working environment and actual needs. It can share a light source emitter with the light source of the continuous lighting system, or different light source emitters can be set separately for the light source of the continuous lighting system.

[0046] As a solid-state light source, an LED light source can be made into light-emitting diodes of different colors by using different materials. According to the principle of colorimetry, white light can be achieved through different color mixing schemes. For example, mixing blue light and yellow light, mixing the three primary colors of blue, green, and red, and mixing multi-primary colors, etc. For example, a blue LED chip and a yellow-emitting phosphor that can be effectively excited by blue light are organically combined to form a white LED.

[0047] The white LED dazzling lamp group adopted in the present utility model, for example, uses an LED chip with a single power greater than 1 watt, integrates multiple chips on a printed circuit board and arranges them in a dot matrix with a certain pitch as a planar light source, and combines them into a white LED dazzling lamp group. For example, 10 3W white LEDs of CREE Company in the United States and a PAM2842 driving chip can be selected.

[0048] In the adaptive strong-light dazzler provided by the present utility model, the ambient light intensity sensing module 30 and the laser ranging module 70 sense the light intensity of the external environment and the distance to the target person. The light source power control unit 50 adjusts the luminous power and light intensity of the light source emitter 60 in real time according to the information transmitted by the ambient light intensity sensing module 30 and the laser ranging module 70, realizing the function of the light intensity of the dazzling lamp beads changing in real time, which can not only ensure the dazzling effect, but also protect the eye safety of the target person, and play a better role in deterring crimes and maintaining public order.

[0049] See Figure 2 , as an implementation manner, the adaptive strong-light dazzler provided by the present utility model includes a housing 1 with a cylindrical cavity 11. The power supply 10 is located at the tail of the housing 1, and the light source emitter 60 is located at the head of the housing 1.

[0050] In some embodiments, the duty switch 20 and the dazzle switch 40 can be separately arranged or closely arranged side by side. Taking the separate arrangement as an example, the duty switch 20 is arranged on the side of the light exit end of the housing 1 (for example Figure 2 at position A in), and at the same time is preferably arranged corresponding to the ambient light intensity sensing module 30 and the light source emitter 60, thereby ensuring the reliability and convenience in the use process; furthermore, the dazzle switch 40 is arranged at the tail of the housing 1 (for example Figure 2 at position B in); in some implementation schemes of the adaptive strong-light dazzler provided by the present utility model, the ambient light intensity sensing module 30, the laser ranging module 70 and the light source power control unit 50 are located in the cylindrical cavity 11 of the housing 1.

[0051] An adaptive strong-light dazzler provided by the utility model obtains the brightness information of the external environment through the setting of an ambient brightness sensing module, further obtains the distance information from the target person through the setting of a laser ranging module, and transmits this information to the light source power control unit, thereby controlling the irradiance of the strong light emitted by the light source emitter, achieving an adaptive strong-light dazzling effect, and playing a better role in deterring crimes and maintaining public order.

[0052] The currently used laser dazzler usually adopts a green laser. Even if the laser power is the minimum of 1W, due to the good focusing of the laser, it will still cause certain irreversible damage to the retina of the target of the strike. If it is used at a power of 12W, the harm to the human retina is even greater. Therefore, the currently used laser dazzler is mainly used to accurately strike the target and is not suitable for front-line police officers to perform law enforcement duties. The LED strong-light source selected by the utility model belongs to incoherent light. Compared with the laser source, the LED source causes less harm to the human body and has lower costs. The adaptive strong-light dazzler provided by the utility model can be used in the process of front-line law enforcement and duty to briefly subdue the target person rather than accurately strike the target person, which is different from the scenario in which the laser dazzler is used.

[0053] The above are only the preferred embodiments of the utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the utility model.
