BACKGROUND OF THE PRESENT INVENTION
1. Field of Invention
The present invention relates to a rotatable headlamp, and more particularly to a clip light which is able to selectively adjust a light projecting angle of the clip light.
2. Description of Related Arts
A conventional headlamp typically comprises a housing, a power source provided within the housing and an illuminating unit mounted in the housing and electrically connected with the power source, wherein the housing is adapted for wearing on a user's head through a strap so that a user is able to wear the headlamp on his or her head for providing illumination when he or she is performing some duties or personal work.
There several disadvantages for this kind of conventional headlamp. First, the headlamp must be affixed to the strap before it can be worn on the user's head. The conventional method is to affix the housing to the strap with little or no room for the housing to move with respective to the strap. In other words, when the housing is affixed to the strap, the illuminating angle of the illuminating unit cannot be freely adjusted. This present a great due of inconvenience to the user because when the user is wearing the headlamp on his or her head and he or she is in the course of performing some tasks, and when the user needs to adjust the angle of illumination so that he or she can view a particular object more clearly, the user has no choice but to either move his or her head to acquire the necessary angle of illumination, or detach the headlamp from his or her head and re-adjust the angle of inclination between the headlamp and the strap. Even this, the latter option may not be available because conventional headlamp may not provide connectors which facilitate pivotal movement between the housing or illumination unit with respective to the strap.
Second, recharging issues of conventional headlamp presents another disadvantage. For conventional headlamp, in order to recharge, the user has to detach the rechargeable battery for recharging. This also induces a great due of inconvenience to the user. When the rechargeable battery is detached from the headlamp, the user has to utilize designated charging equipment, such as a predetermined charger, for charging the rechargeable battery. Very often, however, the charger and the headlamp are separately located so that one may not be able to get the predetermined charger quick enough to resume the operation of the headlamp promptly.
Even if the orientation the headlamp for attaching onto a head band is adjustable, the projecting angle of the headlamp is limited within a predetermined angle or can only be moved in one direction. Therefore, the headlamp is unable to be flexibly rotated for illuminating the desired working area.
Furthermore, the light emitting apparatus mounted on a headband, or coupled at a brim of a hat or a cap have been widely applied for illuminating a dark working area for the freedom of both hands. A LED headlight is a well known type of lighting apparatus detachably coupling at the brim of the cap to illuminate the front crown working area. Take a clipper headlight for example, the clipper headlight has a clipper portion integrally provided at the headlight for attaching the headlight to a baseball type cap. In order to match the curve shape of the brim of the baseball type cap, the clipper on the headlight has a curve shape for detachably mounting on the front brim of the cap in a specific position.
However, the integrated clipper with the headlight is limited of applications. The headlight of fixed curve clipper cannot be reversely coupled to the top side of the brim of the cap. In other words, the headlight must clip at the bottom side of the brim of the cap such that the headlight will block a wearer vision. In addition, the headlight with fixed curve clipper has to be detachably mounted in a certain position on the brim of the cap for stably matching the curve of the baseball type cap. Furthermore, the clipper headlight fixed on the cap or the likes are fixedly toward in one direction only and can hardly be adjusted the projection of the light beam of the headlight to project to the working area. Additionally, the clipper integrated mounted on the headlight can not be detached to switch the clipper for different circumferences.

The second biasing surface 116A is a flat and inclined face arranged to bias against the front side of the housing body 114A when the adjustable head 112A is downwardly and pivotally folded at the second projecting position. Therefore, the first and second biasing surfaces 115A, 116A formed at two individual dimensions are able to generate the relatively wider adjustable light projecting orientation for conveniently illuminating the predetermined area. It is worth mentioning that the light housing 11A can be selectively rotated via the mounting arrangement 30A to move the adjustable head 112A at a left-and-right direction while the adjustable head 112A can be selectively moved via the joint member 113A at the up-and-down direction. In other words, the light projecting angle of the light source 12A can be selectively adjusted at two different dimensions.
As shown in FIG. 13, the power source 20A provided within the housing body 114A of the light housing 11A of the light head 10A may further comprise a battery compartment 21A adapted for receiving one or more batteries, such as rechargeable battery or replaceable battery, and a compartment enclosure 25A provided for enclosing the battery compartment 21A. In the preferred embodiment, the compartment enclosure 25A is preferably provided at an un-attachment surface opposed to the attachment surface of the light housing 11A, so that the compartment enclosure 25A is able to be easily opened for accessing the battery compartment 21A. Accordingly, the compartment enclosure 25A is pivotally coupled at the housing body 114A to selectively enclose the battery compartment 21A when the compartment enclosure 25A is pivotally and upwardly folded with respect to the un-attachment surface of the light housing 11A.
The light source 12A can be a bulb, LED, or the like, and is preferably the LED, wherein the light source 12A may comprise one or more LEDs spacedly and longitudinally supported within the light housing 11A. The LEDs of the light source 12A are electrically connected to the power source 20A preferably powered by the rechargeable battery within the battery compartment 21A to provide an electricity to the light source 12A for generating the light beam toward the light window 111A. The light head 10A may further incorporate with the auxiliary light source 13 as mentioned in the above preferred embodiment for providing additional light to illuminate a designated area or a targeted object aimed by the LED light source 12A.
Accordingly, the power source 20A may further comprise one or more switch controls 22A for controllably switching the light source 12A in an on-and-off manner. The switch control 22A is preferably provided at an opposite unattachment surface of the attachment surface of the light housing 11A and to electrically connected to the power source 20A, so that the switch control 22A is adapted for controlling the clip light in the on-and-off manner. It is worth to mention that the light arrangement can be either mounted at the top side or the bottom side of the visor of the cap via the detachable clipping unit 355A. Therefore, the user is able to actuate the switch control 22A at the unattachment surface of the light housing 11A to control the light head 10A.
As shown in FIG. 12, the light housing 11A further comprises a control guider 110A outwardly protruded from the unattachment surface of the light housing 11A at a position adjacent to the switch control 22A, wherein a height of the control guider 110A is slightly higher than a height of the switch control 22A for blocking the switch control 22A from being actuated unintentionally. Accordingly, the control guider 110A has an arc-shape partially encircling with a rear edge portion of the switch control 22A. Therefore, the switch control 22A must be intentionally pressed down in order to controllably switch the light source 12A in an on-and-off manner.
The light head 10A may further have a light reflection housing 14A having a reflection surface 141A provided to reflectively enhance the light intensity of the light source 12A of the clip light by reflecting the light beam generated form the light source 12A. In other words, the light reflection housing 14A is formed within the adjustable head 112A for retaining the light source 12A therewithin, so that the light beam from the light source 12A and the reflected light reflected from the reflection surface 141A are projected out through the light window 111A of the light housing 11A.
The light housing 11A preferably further comprises a transmissible cover for enclosing and protecting the light reflection housing 11A at the light window 111A and the light source 12A within the light housing 11A. Therefore, the light generated from the light source 12A is projecting through the transmissible cover of the light window 111A.
The rechargeable dock 40 (not shown in this embodiment), as mentioned above, may be adapted for incorporating with the clip light in the preferred embodiment for electrically connecting with an external power supply, such as an external AC power supply, wherein the rechargeable dock 40 preferably has a docking cavity 41 detachably adapted for receiving the light head 10 to charge the power source 20A.
