1. Field of Invention
The present invention is relates to a rechargeable halogen search light and more particularly, to a rechargeable halogen search light which is having an ability to light up 1.5 km radius with a handle and two supporting legs. Said two supporting legs may move relatively and interactively between position one and position two. If both said supporting legs are adjusted to an angle over 90°, user may place said light on shoulder to provide long distance lighting.
2. Description of Related Arts
Military, law enforcement, fire and rescue personnel, security personnel, hunters and recreational boaters among others for nighttime surveillance in any application commonly use handheld halogen searchlights, where a high intensity spotlight is required. Nowadays, such application is highly demeaned in all anti-terrorists actions that take place at nighttime. Conditions of use are highly varied, but generally require the light to deliver a desired field of view at long distances, be reliable, durable and field maintainable in order for it to be practically used in the designed applications. Typically the light is hand carried and must be completely operable using simple and easily access manual controls, which do not require the use of two hands. In prior art xenon short-arc searchlights or illumination systems, whether handheld, portable or fixed mounted, the luminance distribution of the arc has been positioned facing in the direction of the beam (cathode to the rear), to provide a uniform beam pattern when the arc is at the focal point of the parabolic reflector. When the arc is moved slightly beyond (or slightly rearward of) the reflector's focal point, the combination of a placing all available light in the high magnification section of the reflector and collecting it in a slightly convergent manner produces roughly twice the operating range as a conventional anode-forward device.
Also, all prior arts of lanterns are focusing mainly of power sources or power supply to power up lanterns. Seldom of prior arts are aiming to improve lighting angles as most lanterns are used with handheld or placed on a table/floor or even placed with a hat. However, it is very obviously that lantern with an ability to rotate with certain degree of angles s so needed.
U.S. Pat. No. 6,685,337 provides a lanterns which combine both a flashlight with a candle together to ensure said lantern can still light up when power source is done or batteries are all used up. However, the lighting range, lighting angles and the lighting power of a candle are minimal. Such lantern light up by a candle will not be the most useful tool in an event of a big area.
U.S. Pat. No. 6,629,767 discloses a lantern with a batteries compartment with shock absorber lining to protect batteries contained therein from damage due to excessive shock applied to said batteries. Again, this lantern is only aiming a power supply to said lantern but lighting range and lighting angle are being ignored.
U.S. Pat. No. 6,702,452 provides a lantern with a tripod supporting legs. The mounting is a tripod mount so that the portable searchlight may be fixed in the field to a tripod with the second device. The mounting on the handle is a thumbscrew mount to permit mounting of an optical detection device onto the searchlight and rigidly fixed to the housing. However, this lantern provide without no ability to move any angle to obtain a better light range.
The main object of the present invention is to provide a rechargeable compact fluorescent having a supporting means and such supporting means can provide an ability to rotate an angle more than 90 degree so as to provide a platform for user to place said fluorescent on shoulder.
Another object of the present invention is to provide a rechargeable compact fluorescent 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.
Another object of the present invention is to provide a rechargeable compact fluorescent having an ability to adopt difference power source supplies.
Another object of the present invention is to provide a rechargeable compact fluorescent having a supporting means and such supporting mean can provide an adjustable mean with a tight or loose positions so as to controlling such supporting legs in a locked position or in a rotating position to reach the best lighting range and lighting angles.
Accordingly, to achieve the above objects, a rechargeable compact fluorescent comprises:
Referring
As illustrated in figures, said light source (2) consists of an energy-saving halogen bulb (15), which is fastened to a base (21) and is powered by the built-in power source (7) of said illuminant. A power connects to an electric circuit device (8) inside said illuminant (1), an external socket (9), a switch (10) and said connected energy-saving light bulb (15) through a power line. Along the underneath portion of said handle (11), there is a padding (22) made of resilient material to provide comfort when holding this search light. At both ends of said handle (11), there are two latches provided for a detachable belt.
An adjustable long stand (12) is mounted with said illuminant (1). There is an adjustable control (14) provides locking and unlock positions for said long stand (12). Said long stand (12) can pivot around a hinge and remain at any position within the 270° arc, so as to provide a support for said illuminant (1) on a plant surface to achieve a optimal lighting angle. An adjusted short stand (23), is flexibly attached to said long stand (22) and can tightened up with an adjustable latch (14) to fasten said short stand (23). Said short stand (23) may pivot around a hinge and remain at any position within the 270° arc, so as to provide a support for said illuminant (1) on a plant surface to achieve a optimal lighting angle.
There is a flexibly connected battery cover (17) at a back portion of said illuminant (1). Said battery cover (17) is fastened to a flange (16) on back of portion of said illuminant (1) by a metal screw (15). Said metal screw (15) provides a locking mean to a lockable piece (26) located at the end portion of said illuminant (1). By pushing a release latch (27) of said lockable piece (26), said metal screw (15) thereby detach from locking piece (26) and release said battery cover (17), (21), at rear end of said illuminant (1), there is a sealed with a front surface of said battery cover (17) from inside. Said battery cover (17) is fastened to rear end portion of said illuminant (1) in a dismantling manner. After separating said battery cover (17) from said illuminant (1), user can replace batteries therein. There is a sealing head (19) made of resilient materials on top surface of said battery cover (17). Said sealing head (19) is attached to a shield (20), which seals all possible entrance to said external socket (9) to provide protection against damage and intrusion of rain or water.
Said invention, rechargeable compact fluorescent floodlight has adjustable long stand (22) and short stand (23) at its bottom. It allows user to apply said search light without holding it by hand and yet needs sufficient lighting by putting said search light on a supporting surface such as a table or ground.
This rechargeable halogen search light is an important source of lighting mean employed in marine, army, public security, firefighters, emergency treatments, disciplined troops, architecture and civil vessels, as well as for emergency treatment in daily life.
