This application is a US national phase of International Application No. PCT/CN2015/076499 filed Apr. 13, 2015, which claims priority to Chinese Patent Applications No. 201520032865.6 and No. 201520031277.0 filed on Jan. 18, 2015, and No. 201520195264.7, No. 201520195632.8 and No. 201520195181.8 filed on Apr. 2, 2015, the entire contents of which are incorporated herein by reference.
The present disclosure belongs to the field of photoelectric technologies, and more particularly, to an LED light source capable of projecting a graphic logo and a red dot sight thereof.
An existing LED point light source can only emit a point light spot with a single transmission shape. Typically, the transmitted light spot is of a nearly circular shape, or is of an oval shape as required. No matter whatever specific shape of a light spot is needed, this depends mainly on a cross-section shape of an exit pupil manufactured on the LED light source. In other words, light generally forms the light spot transmitted to a surface of an illuminated object after being intercepted via the pupil. Therefore, the shape of the transmitted light spot is determined by the cross-section shape of the pupil.
Nowadays, a large number of the light sources used on a red dot sight generally are LED point light sources, and the light spot transmitted generally is of the circular shape or the oval shape. However, to produce two light spots of different shapes, for example, to produce a round light spot outside a circular light spot, a general practice at present is to use a raster, thereby implementing interception of a cross section of the light spot emitted from an LED surface light source and transmitting the light spot with a specific form because of the interception of the raster. However, with the use of the LED surface light source, a lot of power is wasted due to use of the LED surface light source. Furthermore, only one of the circular light spot and the light spot with a specific shape produced due to a raster effect, rather than both of them, can be used at a time. If they are used simultaneously, an extra light path system is needed, which may make the whole light path complex. Particularly when only one light spot with a specific shape is needed, complexity of operation may be increased, and reliability of the sight is reduced.
Most of the existing red dot sights use batteries. For example, a lithium battery can provide electric energy required by the operation of a red dot module. The batteries have limited service lifetime and need to be replaced, so that use cost is increased. Furthermore, in the process of using, due to the change of illumination of external environment, supplied current or voltage of the batteries needs to be adjusted by means of a regulating switch so as to implement adjustment of the brightness of an output light of the red dot module. For example, when the environment brightness is enhanced, the brightness of the output light of the red dot module needs to be increased. Otherwise, the brightness of the output light of the red dot module needs to be decreased.
Such red dot sight relies on batteries to supply power no matter in the day or at night. Consequently, replacement of the batteries increases the use cost.
For the existing red dot sight, a dustproof cover is generally provided at the exit pupil. Opening or closing the dustproof cover is implemented by upside down of a coupling pin. Opening degree completely depends on an extent that a cover plate is opened by manpower. The cover plate cannot be opened quickly at one go. The cover plate may need to be opened twice and even thrice because the cover plate may be not opened in place once. In this process, fingers may touch other parts, thereby producing vibration, which is not beneficial to stable adjustment of the sight.
Additionally, unlocking an existing installation card track generally is implemented by drawing a lock catch to a trigger portion of a cam handle. Improper force direction cannot effectively apply human power to the lock catch sufficiently. As a result, opening the lock catch needs larger strength and proper angle, and thus the operation is not quickly enough.
The foregoing information is merely disclosed to facilitate understanding of background of the present disclosure. Therefore, the foregoing information may include information not constituting the prior art known to those of ordinary skill in the art.
The utility model aims at overcoming a problem that the existing LED point light source only can generate round or oval light spots, and cannot generate specifically required light spots unless under the cooperation of other optical devices, which causes a problem of complicated system and complex operation;

To overcome a problem that the existing LED point light source generally adopted by a red dot sight only can generate round or oval light spots, and cannot generate specifically required light spots unless under the cooperation of other optical devices, which causes a problem of complicated system and complex operation. This embodiment provides an LED light source capable of projecting a graphic logo as shown in
A radial cross section of the peripheral light source 2 provided by this embodiment is ring-shaped.
To provide a better reference to the sight, in this embodiment, a target image used for a general sight is imitated. As can be known from

As can be seen from
The point light sources 1 and the peripheral light source 2 are placed on the same radial plane.
In conclusion, the LED light source capable of projecting the set graphic logo provided by this embodiment does not need a raster being matched with transmission to obtain a set LED with luminous graphic logo, so that the power consumption is reduced, system design is simplified, product functions are increased, and simplification of structure, convenience of operation and reduction of cost for the red dot sight are facilitated.
As shown in
An existing red dot sight merely relies on a battery to supply electric energy, which causes a problem of high use cost. To overcome this problem, this embodiment provides a battery-powered solar red dot sight as shown in
In this way, electric energy can be provided to the red dot module by virtue of the solar cell 12 as long as sunlight exists. Thus it is ensured that the red dot module works normally and can adapt to change as the ambient brightness changes. For example, when the ambient brightness is enhanced, the brightness of the output light of the red dot module is correspondingly increased, whereas, the brightness of the output light of the red dot module is weakened as the ambient brightness darkens. This does not need manual operation and thus it is convenient. More importantly, the red dot sight always depends on a battery to supply weak power to the red dot module in the case of daily use, and can be supplemented by the solar cell in an environment of sunlight. The red dot module still can normally work by virtue of battery power supply when environment light is weak or absent.
The circuit board is provided with a micro control unit (MCU) and a gear control circuit. The solar cell is connected in series to the red dot module via the MCU, and the battery is connected in series to the red dot module via the MCU and the gear control circuit. As a press button switch, the brightness regulating switch includes a “+” button and a “−” button, wherein the “+” button and the “−” button are respectively connected to the MCU. The MCU cuts off an electrical connection between the solar cell 12 and the red dot module according to an initial input signal of either one of the “+” button and the “−” button, and controls the gear control circuit according to second or multiple input signals of either one of the “+” button and the “−” button to implement regulation of the voltage or current of the red dot module and change the brightness of output light of the red dot module. Furthermore, the MCU cuts off an electrical connection between the battery and the gear control circuit according to a signal simultaneously inputted via the “+” button and the “−” button or no arbitrary input signal being inputted within a period of time, and simultaneously recovers the electrical connection between the solar cell 12 and the red dot module.
The LED lamp as shown in
Based on traditional battery power supply, in this embodiment, a solar cell power supply circuit is especially added, which works with the battery simultaneously, and can continue supplying power by virtue of the battery in an environment lacking sufficient illumination, without affecting the normal use of the sight.
As shown in
Referring to
The solar cell 2 provided by this embodiment is embedded in the top surface of the housing 1 so that the solar cell 12 can receive illumination of sunlight in the longest time with the largest area to provide sufficient and long-time electric energy. To ensure that the solar cell 12 exerts the maximum efficacy, the top surface of the solar cell 12 is provided with protective glass, which may prevent dust from falling and prevent the solar cell 12 from being accidentally scratched.
The solar cell 12 as mentioned in this embodiment may be any one of monocrystalline silicon, polycrystalline silicon, silicon photodiode or weak light type amorphous silicon solar cells.
As can be seen with reference to
Meanwhile, in order that the whole battery bracket 72 can be conveniently taken out from the battery compartment 71, in this embodiment, a groove 77 is particularly formed on the top of the push-pull block 73. By inserting one end of a pick into the groove 77, the whole battery bracket 72 and the battery 76 clamped thereon can be easily pulled out, so that the whole battery bracket 72 is loosened in the battery compartment 71, and then the whole battery bracket 72 can be pulled out by hands.
To prevent vibration generated in use from causing the battery bracket 72 to loosen or even fall out of the battery compartment 71, thereby having a negative effect on the stability of power supply, in this embodiment, left and right edges of the push-pull block 73 are respectively extended toward the left and the right. Screw holes 78 are formed on the extending portions, screw holes are also formed at corresponding positions of the sight, the threaded fixation of the battery bracket 72 and the sight body is implemented by virtue of screws 79 as shown in

One end of the connecting rod 39 is fixedly connected to a circumferential central portion of the connecting pipe 38. The connecting rod 39 is provided with a central annular groove 44 positioned at an axial central portion of the connecting rod 39 and an end annular groove 45 placed at the other end of the connecting rod 39. A first fixing ring 67, a second fixing ring 46 and a third fixing ring 47 are placed on an internal surface of the cover plate 33 along the same diameter direction of a circle sharing the same plane with the cover plate 33. The second fixing ring 46 is placed at a middle position between the first fixing ring 67 and the third fixing ring 47. On the internal surface of the cover plate 33, a first rectangular groove 48 and a second rectangular groove 49 are placed at a side where the second fixing ring 46 and the third fixing ring 47 face toward the first fixing ring 67.
The connecting rod 39 successively passes through the first fixing ring 67, the second fixing ring 46 and the third fixing ring 47. The first return spring 40 is placed between the first fixing ring 67 and the second fixing ring 46, and the second return spring 41 is placed between the second fixing ring 46 and the third fixing ring 47.
One end of the first clamp spring 42 and of the second clamp spring 43 is respectively inserted into the central annular groove 44 and the end annular groove 45, and the other end thereof is respectively inserted into the first rectangular groove 48 and the second rectangular groove 49, so that the first return spring 40 and the second return spring 41 compressed under the action of external forces restore a static length after the external forces disappear, and meanwhile the connecting pipe 38 tightly presses on an end face of the cover plate 33. On the connecting pipe 38, either side of the connecting rod 39 is provided with a clamping piece 50, the end face of the cover plate 33 is provided with a limit groove 51 fitting in with the clamping piece 50 for limiting.
By pulling the connecting pipe 38, the clamping piece 50 is pulled out from the limit groove 51, and then the cover plate 33 is rotated, so as to implement rotation around the connecting rod 39 at arbitrary angles, including 360°. After the connecting pipe 38 is loosened and the external force is withdrawn, the first return spring 40 and the second return spring 41 restore under the action of the first clamp spring 42 and the second clamp spring 43.
The connecting pipe 38 is internally provided with a torsion spring 35, the core shaft 34 passes through the torsion spring 35, and meanwhile the connecting pipe 38 is provided with an axial opening 52, so that a tail end 53 of the torsion spring 35 extends to outside the connecting pipe 38 and presses against the ear hole 36 to produce a force to open the cover plate 33. In this way, the cover plate 33 can be quickly opened.
The opening 52 is placed at a rear side of the clamping piece 50. The opening 52 and an axle of the connecting rod 39 are respectively placed on two sides of the clamping piece 50.
As can be seen from
To allow the dustproof cover to be mounted on a light outlet hole of the sight, in this embodiment, an embedded honeycomb seal (as shown in
The sliding lock catch 61 includes a straight connecting portion 67 parallel to a bottom surface (parallel to the lateral surface of the base 68) of the card track portion 70, an internally vertical portion 63 and an externally vertical portion 64 perpendicular to the bottom surface of the card track portion 70. The internally vertical portion 63 and the externally vertical portion 64 are respectively connected to two ends of the straight connecting portion 67.
With reference to
An outer side edge at a top of the internally vertical portion 63 is provided with an arc-shaped guide surface, and a rear end edge of the arc-shaped guide surface extends to the externally vertical portion 64 to form a hook portion so that a locking notch 65 on the cam handle 69 can be inserted or drawn out to implement or relieve limit and fixation of the cam handle 69. The internally vertical portion 63 is vertically fixed to the straight connecting portion 67 by a pin bolt 66. Specifically, a screw hole is formed downward at the top of the internally vertical portion 63, and a corresponding position of the straight connecting portion 67 is provided with a screw hole, so that fixed connection can be implemented through a pin 66.
This installation card track differs from the existing installation card track in that the sliding lock catch 61 is pushed toward a cam portion of the cam handle 69 when the cam handle 69 is opened, so that the arc-shaped guide surface of the internally vertical portion 63 is far away from the rear edge of the locking notch 65 on the cam handle 69, the hook portion may be separated from the locking notch 65, and limit release of the cam handle 69 may be implemented by upwardly pushing the tail end of the cam handle 69 (namely a trigger portion 60 of the free end). Compared with the traditional manner of pulling back to open the locking notch, by using this operation manner, when locking limit is contacted, it is only needed to forwardly push the sliding lock catch 61, while when locking limit is released, it is only needed to fasten the cam handle so that the locking notch 65 of the cam handle is guided in so as to fit in with the arc-shaped guide surface of the read end at the top of the internally vertical portion 63. This operation meets operation habits of a person, has the advantage of convenient operation and is beneficial to rapid operation.
To adapt to a requirement for height adjustment of the sight, this embodiment provides a card track pad 80 (as shown in
