ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a laser sight, in particular to a laser sight that provides an illumination effect by symmetrically positioning a plurality of LEDs around the light output of a laser.
2. Description of the Prior Art
The fact that a laser diode emits a high concentration of light allows it to be used in indication, positioning and gunshot sighting. The structure of a conventional laser sight is shown in
FIGS. 1 and 2
, and includes a laser box
10
that has a cover
11
having a laser diode
12
whose emitting light can be projected out through an opening
112
installed at the upper side of the laser box
10
. A battery
13
is positioned below the cover
11
, and can be a 3.6 volts lithium battery, with a protecting plate
114
covering the battery inside the cover
11
. A flashlight rack
14
is installed below the laser box
10
to affix a flashlight
15
thereto so as to be able to do shooting at night. A clipping groove
116
is disposed at each flank side of the cover
11
of the laser box
10
, each groove
116
being utilized to buckle up one end of two clipping plates
142
of the flashlight
14
. A set of screws
145
can be adjusted to clamp the two clipping plates
142
tightly, enabling a flashlight
15
to be held inside the flashlight rack
14
and the two clipping plates
142
to be clamped tightly below the cover
11
of the laser box
10
.
Thus, in a conventional laser sight, a flashlight is added to the outer part of the laser box
10
to provide illumination. Since the flashlight and the laser sight operate separately, there is often a lack of consistency in sighting a target during shooting. In this regard, the illumination direction of the flashlight and the aiming direction of the laser sight are not aligned, which consequently can cause a shooter to take inaccurate aims. Additionally, the conventional laser sight is not waterproof, so that bad weather or perspiration may lead to the short circuit of the laser sight.
SUMMARY OF THE INVENTION
It is an objective of the present invention to provide an illuminable laser sight.
It is another objective of the present invention to provide a laser sight having a light source positioned with respect to the laser diode in a manner so that the illumination provided by the light source is coaxial to the sight line emitted by the laser diode.
It is yet another objective of the present invention to provide an illuminable laser sight whose aiming and illumination functions may be consistently operated by actuating a single switch.
It is yet a further objective of the present invention to provide an illuminable laser sight that is waterproof.
The objectives of the present invention can be accomplished by providing an illuminable laser sight having a power source, a laser module coupled to the power source and having a laser diode for emitting laser beams, and an adjuster module positioned around the laser module and coupled to the power source, the adjuster module having a front face and a laser light exit formed at the center of the front face and aligned with the laser diode. The laser sight further includes an illuminator module positioned adjacent the front face of the adjuster module, the illuminator module having a plurality of LEDs arranged in an annular manner to define a central bore that is axially aligned with the laser light exit and the laser diode.
