The present invention relates to a halogen spotlight, and more particularly relates to a halogen spotlight equipped with a circuit adopts direct current power supply, power generated by automobile and batteries along with an exhaust pipe at its end portion to release exceed air pressure within said halogen spotlight due to changes of weather and climate.
1. Field of Invention
Majority of conventional halogen spotlight normally consist of a main body and a spotlight, however, they always have a flaw such as they can only employ a single source of power supply. When such single source of power supply went out, halogen spotlights are useless unless a replacement of power supply occurred. However, it is very inconvenient to replace lighting source when use halogen spotlight during life-saving actions and during any policing or military strikes.
Moreover, most conventional halogen spotlights cannot adopt changes due to weather and climates. Most of the times we find halogen spotlights are exploded due to exceed air pressure caused by weather and climates. It is very dangerous for users.
Also, most conventional halogen spotlights provide can only adopt one power source, normally power generated by batteries. It is very inconvenient for users when using such halogen spotlights in different occasions.
2. Description of Related Arts
A main object for the present invention is to provide a halogen spotlight having adoptability to more than one power supply source.
Another object for the present invention is to provide a halogen spotlight having adoptability to any changes of weather and climates therefore; it will not be exploded so easily.
Another object for the present invention is to provide a halogen spotlight having adoptability to allow regular batteries combined into a bigger power supply for extended usage.
Another object for the present invention is to provide a halogen spotlight having a supporting means and such supporting mean can provide an ability to rotate and/or to move any angles within 270 degree circular arc.
Accordingly, in order to accomplish the above objects, the present invention provides a halogen spotlight comprising:
The present invention comprises a three-dimensional-type-cylinder structure body (1), a source of lighting (2) inside said body (1), a parabola-shaped reflector (3) and a transparent front panel (4). It uses a sealing washer (5) to seal off an inner surface of said front panel (4) with said reflector's (3) surface in front of annular nut (6). Said annular nut (6) is secured in a front portion of said body (1) in a detachable manner.
As illustrated in all figures, said source of lighting (2) consists of a bulb, which is powered by a chargeable battery (7) in said body (1). A power supply is connected to an electric circuit in said body (1) via wiring. Plug receptacle (9) and switch knob (10) are connected in such a manner to control power supply from going into said electric circuit to light up and turn off said bulb. In addition, said electric circuit is having adoptability to power source generated by a battery box (11), said chargeable battery (7) and the conventional AC power supply from public utility as well as power supply generated by automobiles, boats and other means of transportation vehicles. There are also a plurality of lamp body and stand for replaceable installation of the light on the stand; Supporting means (13) are connected with said body (1). When an adjustable hinge is tightened, said supporting legs (13) are firmly fixed in one position. However, said supporting legs (13) can also provide rotating positions through a adjustable hinge to any position within 270 degrees circular arc. They provide support for said body (1) in a horizontal position to get the best lighting angle.
A handle bar (12) is connected to said body (1). Said handle bar (12) is a rectangular structure, under which there is a handle (13) made of flexible materials that provides comfortable grip for users. In both front and back portion of said handle bar (12), there are shoulder buckles (14) for convenience of carrying this spotlight by users.
Said reflector (3) inside said body (1) is connected with a frame (15), a rear surface of said frame (15), which installs contact metal plate (16) that connects to a battery power, as well as electric circuit device (8), plug receptacle (9) and switch knob (10) that connect to a bulb. It is obvious that said frame (15) is placed inside said body (1) in a moveable manner. Said contact metal plate (16) on a rear surface of said frame (15) is assembled to said battery box (11) and said chargeable battery (7) provides power alternatively.
Said switch knob (10) is secured on a top portion of said frame (15) in said body (1). There is a circular hole (19) on top portion of said switch knob (10). A circular hole (19) lies on a top portion of said body (1). Said switch knob (10) runs through said circular hole (19) in said body (1) to a pressing button (17) that is secured to an inner surface of a pressing component (18) made of flexible materials. A shield (20) is pressed and sealed onto said body (1) on top of said pressing component (18). When said button (17) is at its pressed position and connecting to said component (18), and thus said button (17) presses said switch knob (10) to connect power to lighten said bulb.
There is an exhaust pipe (21) at rear end of said body (1). An annular nut (22) made of flexible material on top of said exhaust pipe (21) is used to seal up an exit of said exhaust pipe (21) so that rain does not run through from said exit of said exhaust pipe (21) to enter into said body (1). However, should air pressure and temperature within said body (1) are higher than those outside said body (1), the air will discharge from said body (1) through said annular nut (22) made of flexible materials at said exit of said exhaust pipe (21).
From the foregoing, the present invention is easy to use in searching targets, especially useful for high-risk workers, such as navy, marine, land force, infantry, field army and air force, aerospace technicians, armed police, firefighters, riot police, special troops, public security station, disciplined force, emergency treatment, civil construction and vessels, and indispensable for amateurs of hiking, suburban expeditions, fishing and alpine skiing.
