Patent Application
20190249861
The present invention relates to a pulsed shock light device, and more specifically, to an assembly of a body and a pulsed light module with an optical lens and LED chips for outputting shock light with different colors and dual-carrier frequencies.
Electrical equipment incorporating a flashlight or the like and a plurality of LEDs has been known to stimulate visual senses and cause disorientation in attackers by outputting pulsed or shock light with different colors and dual-carrier frequencies. For example, U.S. Pat. No. 8,984,234 entitled “MULTI-COLOR FLASHLIGHT HAVING GUARDING STICK” provides a typical example of such.
Said patent discloses a cylindrical receptacle coupled with a light mount and groups of red and blue LED chips alternatingly arranged therein. When the flashlight is activated via an actuating module, the red and blue LED chips controlled by a flashing device emit a pulse of alternating red and blue light in order to shock and disorient adversaries by causing them to have vertigo. This is particularly useful for law enforcement officers, security guards, or the like.
A drawback of this type of flashlight or pulsed shock light device in terms of its structure and application is that the plurality groups of red and blue LED chips need to be arranged in an alternating fashion, which inevitably demands a larger light mount in order to accommodate them. Not only does this increase the weight and the manufacturing cost of the device, the form in which the pulsed light are emitted by the LED chips is not conducive for targeting smaller areas of the head, such as the area of the eyes, thereby reducing the effectiveness of such a device.
As known by those of ordinary skill in the art, the lengths and sizes of conventional flashlights or pulsed shock light devices tend to be quite large, which makes them inconvenient for women or children to use or carry around, and cannot be easily drawn under emergency situations. These are not desirable characteristics.
Representatively speaking, those prior-art documents disclose the structure and application of conventional flashlights or pulsed shock light devices. They also reflect some of the shortcomings when the devices are being used in practice. A re-design of the structure different from that of the conventional is called for and will allow for a change in the way it is used. A more effective pulsed shock light transmission and mechanism should also be achieved to overcome the drawbacks of the prior art.
A solution to these drawbacks has not been disclosed or taught by the aforementioned prior-art.
In view of the above, the present invention provides a pulsed shock light device includes an assembly of a body and a pulsed light module. The body is formed with a flat area and a curved area opposite to the flat area to facilitate gripping thereof by a user. The body includes an energy storage unit and an actuating module electrically connected with the pulsed light module. The pulsed light module includes a light emitting chipset for emitting light of different colors and dual-carrier frequencies and an optical lens assembled with the light emitting chipset. The optical lens allows light to be outputted to form a diameter of an illumination range of about 21 cm˜30 cm at a distance between about 200 cm˜300 cm, which covers 150% 200% of the area of a human head, thereby achieving more effective disorienting effects than the prior art.
According to the pulsed shock light device of the present invention, a groove is formed on the flat area of the body to accommodate an affixed member that is a strip-shaped structure made of rubber or similar material to increase friction or resistance between a user's hand and the device. Additionally, the affixed member is allowed to be pulled away from the device to elastically fasten the fingers of the users to prevent the device from slipping or falling.
According to the pulsed shock light device of the present invention, the optical lens forms a light guide of a solid bowl structure, and is defined with a center reference axis. A concave portion is provided at the bottom of the optical lens to receive the light emitting chipset. A (columnar) chamber is provided at the center of the optical lens extending along the center reference axis for guiding light towards the center to thus increase the intensity of light at the center of the illumination range (or illumination profile), allowing the pulsed shock light to be focused more around the areas of the eyes of an attacker.
Referring to
In the following descriptions, terms such as “front”, “front end”, “bottom”, “rear end”, “outside”, and “inside” are referenced with respect to the directions shown in the diagrams.
In the diagrams, the pulsed light module 10 is assembled at the front of the body 90. A groove 93 is provided on the flat area 91 to accommodate or receive an affixed member 20. The affixed member 20 is a strip-shaped structure made of rubber or similar materials to increase the coefficient of friction or resistance between the body 90 and the hand holding it.
In this embodiment, an energy storage unit 30, an actuating module 40 electrically connected with the pulsed light module 10, and a circuit module 50 are provided inside the body 90. The circuit module 50 is well-known in the art and will not be described in details. A buzzer 60 is also provided in the body 90 as shown in
In
In this embodiment, the body 90 is provided with a first hole 96 and a second hole 97 for receiving a first control key 98 and a second control key 99, respectively. The first and second control keys 98 and 99 control the “on/off” of the pulsed light module 10.
Additionally, the height (or position) of the first control key 98 is slightly lower than the surface of the body 90 or the height (or position) of the first hole 96 to reduce actuating the first control key 98 by accident. The second hole 97 is a long-oval shaped structure, and the second control key 99 has a raised portion 99a to be operated by the user, such that the second control key 99 can be freely moved within the second hole 97.
In an embodiment, the pulsed light module 10 includes a light emitting chipset 11 capable of emitting light of different colors and dual-carrier frequencies, and an optical lens 12 assembled with the light emitting chipset 11. The light emitting chipset 11 are composed of a LED chip that emit white, red and blue light, or a configuration of two red LED chips, one white LED chip, and two blue LED chips arranged in an array or at intervals and enclosed together in the same package to reduce the size and weight of the light emitting chipset 11.
When the user operates or presses the first control key 98, the pulsed light module 10 can be turned on/off to output white light, so it can be used for illumination or as a flashlight. When the user operates the second control key 99, the pulsed light module 10 can be turned on/off to output alternating red and blue flashing light, which may occur with the selective triggering or actuating of the buzzer 60 to sound an alarm.
It should be noted that the frequencies of red and blue LED chips are both modulated at about 50-60 Hz in addition to being modulated with a frequency of about 12-15 Hz. Therefore, each of the red and blue LED chips can emit dual-carrier pulsed light with dual frequencies of 50-60 Hz and 12-15 Hz. The luminous intensity outputted by the flashing light emitting chipset 11 (or both the red LED chips and blue LED chips) is at least 7,000 cd (candela). The alternating flashing of the red and blue light with said flashing frequencies results in an increased dazzling effect on the eyes.
With reference to
In this embodiment, a concave portion 14 is provided at the bottom of the optical lens 12 for receiving the light emitting chipset 11. A (column-shaped) chamber 15 with a curved face 16 at the bottom thereof is provided at the center of the optical lens 12 extending along the center reference axis X for guiding light rays towards the center before outputting them.
As shown in the diagrams, light rays from the light emitting chipset 11 pass through the concave portion 14, some of them are emitted on the light guiding layer 13 before being outputted, while some other light rays from the light emitting chipset 11 are refracted and focused in the chamber 15 via the curved face 16 before being outputted. As such, as shown in
In one embodiment, while an angle between the periphery of the optical lens 12 and the center reference axis X (or a “spreading angle” between the periphery of the optical lens 12 relative to the center reference axis X) is about three degrees (3°), i.e., the spreading angle of the periphery of the optical lens is about 6° in total, (i.e. the angular spreading of the optical lens 12 shown in
It should be noted that the above diameter of about 21 cm˜30 cm of the illumination range S is derived from formula: 2*200 cm*Tan 3°≈21 cm 2*300 cm*Tan 3°≈31 cm.
Referring to
Representatively speaking, the pulsed shock light device is light and easy to carry, and includes the following advantages and features compared to the prior art:
1. The assembled structure of the body 90 and the pulsed light module 10 has been redesigned. For example, the body 90 includes the flat area 91, the curved area 92, and the affixed member 20 for increasing friction or securing, and the body 90 is provided with the actuating module 40 and the buzzer 60. The turning on/off of the affixed member 20 is controlled by the first control key 98 and the second control key 99. The pulsed light module 10 is provided with the light emitting chipset 11 for emitting white, red and blue light and the optical lens 12. The optical lens 12 includes the concave portion 14 for receiving the light emitting chipset 11, the columnar chamber 15 and the curved face 16 to increase the intensity of the light at the center area C of the illumination range S. These are in contrast with the traditional structure.
2. More particularly, the light emitting chipset 11 includes red and blue LED chips, which are both modulated at a frequency of about 50-60 Hz in addition to being modulated with a frequency of about 12-15 Hz. Therefore, each of the red and blue LED chips can emit dual-carrier pulsed light with dual frequencies of 50-60 Hz and 12-15 Hz. Additionally, the angular spreading of the periphery of the optical lens 12 is about 3 degrees, so that while at a distance of about 200 cm˜300 cm, the illumination range S will be capable of covering 150%˜200% of the area of a human head, thereby creating more disorienting and dizziness effects than the prior art.
Therefore, the present invention provides an effective pulsed shock light device that is structurally different from the prior art and has advantages over the prior art.
