As shown in FIGS. 2 and 3, the head lighting arrangement 20 further comprises a ring shaped circuit board 22 encircling with the objective end 111 of the scope body 11, wherein the illumination elements 21 are spacedly mounted on the circuit board 22 to be supported at the objective end 111 of the scope body 11.
Each of the illumination elements 21 is a light diode operatively coupled at the circuit board 22 for light generation. Accordingly, the illumination elements 21 are grouped into at least two sets for generating different colors. Preferably, the first set of illumination elements 21 is red navigation light set while the second set of illumination elements 21 is white navigation light set. The red navigation light set will generate red navigation light for preserving night vision. The white navigation light set allows the operator to see clearly under dark environment.
In order to support the head lighting arrangement 20 at the objective end 111 of the scope body 11, the scope body 11 comprises a lens housing 14 for housing the illumination elements 21, wherein the lens housing 14 is coaxially and frontwardly extended from the objective end 111 of the scope body 11. As shown in FIG. 3, the lens housing 14 has a ring shape coaxially mounted at the objective end 111 of the scope body 11 to house the illumination elements 21 in a circular configuration. In addition, the protection lens 123 is supported by the lens housing 14 and is located coaxially within the illumination elements 21. In other words, the lens housing 14 not only supports the illumination elements 21 but also retains the protection lens 123 in position so as to ensure the illumination elements 21 to encircle around the protection lens 123, as shown in FIG. 5. It should be appreciated that the lens housing 14 can be integrally, coaxially and frontwardly extended from the objective end 111 of the scope body 11 to form a one piece integrated structure.
In particular, the lens housing 14 comprises an outer ring 141 and an inner ring 142 coaxially supported within the outer ring 141 to define a light cavity 143 between the outer and inner rings 141, 142, wherein the illumination elements 21 are spacedly received in the light cavity 143 between the outer and inner rings 141, 142. Accordingly, the diameter size of the circuit board 22 matches with the diameter size of the light cavity 143, such that the circuit board 22 is fittedly supported within the light cavity 143 to support the illumination elements 21 between the outer and inner rings 141, 142.
Also, the protection lens 123 is sealed and supported within the inner ring 142 to ensure the protection lens 123 to be supported in front of the objective lens 121. It is worth mentioning that the protection lens 123 can be a transparent glass to protect the objective lens 121.
The scope assembly 10 further comprises a ring shaped front rim cover 15 attached to the outer and inner rings 141, 142 to enclose the light cavity 143. As shown in FIG. 3, the front rim cover 15 has a center lens window 151 aligned with the protection lens 123 and a plurality of light windows 152 aligned with the illumination elements 21 respectively. Accordingly, the front rim cover 15 is coupled at the lens housing 14 to enclose the illumination elements 21 and the circuit board 22 in the light cavity 143. The light windows 152 are spacedly formed at the front rim cover 15 to align with the illumination elements 21, such that the navigation light generated by the illumination elements 21 will pass through the light windows 152 from the light cavity 143.
According to the preferred embodiment, the head lighting arrangement 20 further comprises a ring shaped transparent panel 23 disposed in the light cavity 143 to cover the illumination elements 21 on the circuit board 22, wherein the transparent panel 23 is located behind the front rim cover 15 to protect the illumination elements 21. Preferably, the transparent panel 23 is made of resin to seal and protect the illumination elements 21 on the circuit board 22. It is worth mentioning that since the illumination elements 21 are light diodes, the light diodes do not have any protection. The existing LED generally comprises the light diode encased within a LED housing. In other words, dust or dirt may be entered into the light cavity 143 through the light windows 152 of the front rim cover 15 to damage the illumination elements 21. Therefore, the transparent panel 23 will protect the illumination elements 21 from getting dust or dirt through the front rim cover 15, so as to prolong the life span of the illumination elements 21.
As shown in FIGS. 2, 4 and 5, the scope of the present invention further comprises an integrated control module 30 provided at the attachment base 13 to operatively link with the scope luminous element 16 of the scope assembly 10 and the illumination elements 21 of the head lighting arrangement 20. In particular, the integrated control module 30 is provided at the supporting member 131 of the attachment base 13 to control the operations of the scope assembly 10 and the head lighting arrangement 20.
Accordingly, the integrated control module 30 comprises a power source compartment 31 formed at a sidewall of the supporting member 131 of the attachment base 13 for receiving a power supply as a single power source to operatively link with the scope luminous element 16 and the illumination elements 21, and a compartment cover 32 detachably coupled at the sidewall of the supporting member 131 of the attachment base 13 to enclose the power source compartment 31. Therefore, the scope luminous element 16 and the illumination elements 21 will share one single power source to reduce the overall weight of the scope on the firearm 90 and to simplify the electrical configuration of the scope with respect to the scope luminous element 16 of the scope assembly 10 and the illumination elements 21 of the head lighting arrangement 20.
The integrated control module 30 further comprises a control panel 33 provided at sidewall of the supporting member 131 of the attachment base 13 for adjustably can rolling a scope reticle illumination, for adjustably controlling a brightness level of the navigation light, and for selecting colors of the navigation light. The control panel 33 comprises a plurality of control switches 331 operatively linked to the scope luminous element 16 and the illumination elements 21 for the operator to selectively adjust the properties of the scope luminous element 16 and the illumination elements 21.
As shown in FIG. 5, there are nine illumination elements 21 radially located at the objective end 111 of the scope body 10. For example, the first and ninth illumination elements 21 are grouped to form the red navigation light set and the second to eighth illumination elements 21 are grouped to form the white navigation light set.
One of the control switches 311 serves as an activation switch to activate the head lighting arrangement 20 in different modes. In the first mode, when the activation switch is pressed or touched, the red navigation light set is activated to generate red navigation light. In the second mode, when the activation switch is pressed again, only the second and eighth illumination elements 21 in the white navigation light set are activated to generate white navigation light. At the same time, the first and ninth illumination elements 21 in the red navigation light set are deactivated. In the third mode, when the activation switch is pressed in a third time, only the second, fourth, sixth, and eighth illumination elements 21 in the white navigation light set are activated to generate white navigation light. The first and ninth illumination elements 21 in the red navigation light set are remained deactivated. In other words, the light intensity of the white navigation light in the third mode is higher than that in the second mode. In the fourth mode, when the activation switch is pressed in a fourth time, all the illumination elements 21 in the white navigation light set are activated to generate white navigation light. The first and ninth illumination elements 21 in the red navigation light set are remained deactivated. In other words, the light intensity of the white navigation light in the fourth mode is higher than that in the third mode. In the fifth mode, when the activation switch is pressed in a fifth time, the illumination elements 21 are deactivated so as to switch off the illumination elements 21. Therefore, the operator is able to not only select the activation between the red navigation light set and the white navigation light set for selecting colors of the navigation light, but also adjust the brightness level of the white navigation light.
Furthermore, two of the control switches 331 serve as a brightness increasing control and a brightness reducing control of the scope reticle. When one of these control switches 331 is pressed or touched, the scope luminous element 16 is activated to illuminate the scope reticle. Then, when the brightness increasing control is pressed or touched, the light intensity of the illumination light generated by the scope luminous element 16 will be increased to illuminate the scope reticle. Likewise, when the brightness reducing control is pressed or touch, the light intensity of the illumination light generated by the scope luminous element 16 will be reduced to illuminate the scope reticle. When the two control switches 331 are pressed or touched at the same time, the scope luminous element 16 is deactivated.
It is worth mentioning that all the control switches 331 are provided at the same sidewall of the supporting member 131 of the attachment base 13, such that the operator is able to easily reach the control switches 331 by his or her finger in order to control both of the operations of the scope assembly 10 and the head lighting arrangement 20. In other words, the integrated control module 30 provides a one hand operation for the operator to control the scope. Therefore, the operator can hold the firearm 90 and operate the integrated control module 30 at the same time.
It is worth mentioning that after the scope assembly 10 is mounted on the firearm 90, the operator is able to adjust the scope axis 101 in parallel with the barrel axis 91 of the firearm 90. Once the scope alignment of the scope assembly 10 is adjusted in parallel with the barrel axis 91 of the firearm 90, the light alignment of the head lighting arrangement 20 will be automatically aligned with the barrel axis 91 of the firearm 90. Therefore, the operator is able to adjust the scope alignment of the scope assembly 10 once to achieve both the scope alignment of the scope assembly 10 and the light alignment of the head lighting arrangement 20 in parallel with the barrel axis 91 of the firearm 90.
One skilled in the art will understand that the embodiment of the present invention as shown in the drawings and described above is exemplary only and not intended to be limiting.
It will thus be seen that the objects of the present invention have been fully and effectively accomplished. The embodiments have been shown and described for the purposes of illustrating the functional and structural principles of the present invention and is subject to change without departure from such principles. Therefore, this invention includes all modifications encompassed within the spirit and scope of the following claims.
