TECHNICAL FIELD

The present disclosure is generally related to firearm accessories and, more particularly, to a sight with light reflection indicator for firearms.

BACKGROUND

Unless otherwise indicated herein, approaches described in this section are not prior art to the claims listed below and are not admitted as prior art by inclusion in this section.

Reflex sights, or reflector sights, are widely used in the defense industries, shooting sports, as well as personal defense to assist target aiming. In principle, a reflex sight is an optical sight that allows the user to look through a partially reflecting lens and see an illuminated projection of an aim point (e.g., a dot or some geometric shape) superimposed on the field of view. The size of the aim point (e.g., a dot) more ore less impacts the efficiency in aiming and accuracy in shot placement. For example, a dot sized for 1 minute of angle (MOA) tends to be very small and can help the user to aim the target precisely; however, the small-sized dot tends to be difficult for human eyes to find. On the other hand, a dot sized for 6 MOA tends to be large and can be easily picked up by human eyes; however, the large-sized dot cannot provide the kind of pin-point precision in aiming as does a small-sized dot. Currently available reflex sights on the market are typically sold with a fixed size of aim point. As such, a user would need to buy multiple reflex sights each with a respective size of aim point in order to have different MOAs to suite different needs, but this could be cost prohibitive and hence not ideal. There is, therefore, a need for a solution of a new reflex sight design that provides a user the flexibility in varying the size of the aim point to suit the needs of the user to accommodate different usage scenarios.

SUMMARY

The following summary is illustrative only and is not intended to be limiting in any way. That is, the following summary is provided to introduce concepts, highlights, benefits and advantages of the novel and non-obvious techniques described herein. Select implementations are further described below in the detailed description. Thus, the following summary is not intended to identify essential features of the claimed subject matter, nor is it intended for use in determining the scope of the claimed subject matter.

In view of the aforementioned issues, an objective of the present disclosure is to propose innovative designs of a reflex sight with an aim point the size of which is adjustable or otherwise variable. It is believed that the proposed designs can avoid or otherwise minimize aforementioned issues associated with conventional reflex sights.

In one aspect, an apparatus implementable on a firearm may include a reflex sight which may include a lens, a light source, and a control unit coupled to control the light source. The light source may be configured to project an image of an aim point onto the lens. In operation, the control unit may be configured to vary a size of the image projected onto the lens by the light source without changing a shape or an outer contour of the image.

In another aspect, an apparatus implementable on a firearm may include a reflex sight which may include a lens, a light source, and a control unit coupled to the light source. The light source may be configured to project an image of an aim point onto the lens. In different modes, the control unit may be configured to control the light source to light up different portions thereof to vary a size of the image projected onto the lens by the light source without changing a shape or an outer contour of the image.
