## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
This application is a continuation-in-part of U.S. patent application Ser. No. 11/426,022 filed Jun. 23, 2006 (now U.S. Pat. No. 7,163,309), which is a continuation of U.S. patent application Ser. No. 10/758,107 filed Jan. 16, 2004 (now U.S. Pat. No. 7,118,241), both of which are incorporated by reference herein.


FIELD OF THE INVENTION
The present invention relates to a clip type light emitter, and in particular to a clip type light emitter capable of enhancing a visual field at night by detachably engaging a clip type light emitter to a hat or leisure cap generally used for sports, travel, etc.
BACKGROUND OF THE INVENTION
In general, in order to protect the face of a user from sunlight while ensuring the user's field of vision during leisure activity or sports activity, such as mountaineering, fishing, exercising, traveling, hiking, or jogging, the user wears a cap having a visor protruding from the front section of the cap. The user may also wear the cap when working, including at night.
Although the cap does not cause special problems when the user is engaged in daytime activities, such a cap does not ensure the user's field of vision at night, so the user must carry a light source (e.g. a flashlight).
In addition, since the user must move while gripping the light source when the user is engaged in night activities, the activity of the user may become impeded. Further, since the user must move along the path illuminated by the light, the user may be careless of peripheral environment, resulting in an accident.
Moreover, in the case of night work requiring illumination, the worker must illuminate the working place by gripping the light source in one hand. Accordingly, the worker has to perform the work singlehandedly, causing inconvenience. In addition, when it is necessary to perform the work using both hands, another worker is necessary to hold the light source.
To solve the problems described above, the applicant of the present invention has obtained U.S. Pat. Nos. 7,118,241 and 7,163,309, which disclose a clip type light which may be detachably coupled with a cap visor.
As illustrated in FIG. 1, this clip type light includes a plurality of electric lamps 24 (e.g., LEDs, incandescent bulbs, or the like) installed at the front side of a case 22. A switch 26 operating the electric lamps 24 is installed at one side of the case 22. A battery is accommodated in the case 22, and a clip 28 having elasticity is provided on the case 22, in which one side/end of the clip 28 is integrally formed with the top of the case 22.
In the conventional clip type light having the above structure, if the user pushes the clip type light from the front side to the rear side of the cap visor, the other end of the clip having one end fixed to the case moves upward, so that the cap visor is fixedly inserted between the case of the lamp and the clip. In this state, if the user operates the switch installed at one side of the case, the electric lamps turn on, thereby illuminating the area in front of the cap visor.
SUMMARY OF THE INVENTION
An object of the present invention is to provide a clip type light, which is easily attached or detached from a cap visor while keeping an external appearance of the cap visor regardless of the various curved configurations of the cap visor, without causing damage to an outer skin of the cap visor, while preventing the lamp from moving or separating from the cap visor even if the user is involved in intensive activities.
The clip type light may include a switch, which is provided at a lower portion of a body of the clip type light so as to operate an electric lamp and an ultrasonic wave generator (e.g., ultrasonic insect repellent) in such a manner that the user can easily operate the electric lamp and the ultrasonic wave generator while wearing the cap equipped with the clip type light.
The ultrasonic generator may be provided at a lower portion of the clip type light in order to generate ultrasonic waves to prevent insects from gathering in the vicinity of the electric lamp of the clip type light.

DETAILED DESCRIPTION OF PREFERRED VERSIONS OF THE INVENTION
Hereinafter, clip type lights according to various embodiments of the present invention will be described with reference to the accompanying drawings.
As shown in FIGS. 2, 3 and 4, the clip type light according to the first embodiment of the present invention includes a body 110, in which a battery is accommodated. An upper portion of the body 110 closely adheres to a lower portion of a cap visor 300 having a smoothly curved surface. A plurality of electric lamps 120 are provided at the front portion of the body 110. First end portions of first and second clips 131 and 132 are fixed to the front portion of the body 110 and second end portions of the first and second clips 131 and 132 are elastically movable away from and towards the upper portion of the body 110.
The first and second clips 131 and 132 include first and second protrusions 131a and 132a, which have arc-shaped section and are integrally formed with the front portion of the body 110 while slightly protruding beyond the front portion of the body 110, and first and second clip fixing sections 135 and 136, which extend downward from the first and second protrusions 131a and 132a. 
In addition, the first and second protrusions 131a and 132a define first and second locking holes 131b and 131b such that a rim of the cap visor 300 can be securely rested in the first and second locking holes 131b and 131b. 
In order to allow the clip type light to be easily coupled with the cap visor 300, center portions of the first and second clip fixing sections 135 and 136 make contact with the body 110 and the end portions of the first and second clip fixing sections 135 and 136 are slightly bent upward.
As mentioned above, the clip type light according to the present invention includes a split type clip divided into two parts, so the clip can be attached to the cap without deforming the outer appearance of the cap.
A switch 140 is installed at a lower side of the body 110 in order to operate the electric lamps 120 and an ultrasonic wave generator (not shown) accommodated in the body 110. In addition, a plurality of ultrasonic wave ports 150 are formed at upper and lower portions of the body 110 so as to allow ultrasonic waves generated from the ultrasonic wave generator to be easily emitted out of the body 110.
If the user pushes the switch 140 one time, the electric lamps 120 are turned on, thereby irradiating light. In addition, the ultrasonic wave generator accommodated in the body 110 is also operated, generating ultrasonic waves. In this state, if the user pushes the switch 140 again, the electric lamps 120 may strobe or flicker in a predetermined time interval, but the ultrasonic wave generator continuously generates the ultrasonic waves. In this state, if the user pushes the switch 140 one more time, the electric lamps 120 are turned off and the operation of the ultrasonic wave generator stops.
As shown in FIG. 3, the switch 140 protrudes from the bottom surface of the body 110, preferably, in the form of a hemispherical structure, so as to allow the user to easily operate the switch 140.
Meanwhile, a connection jack 160 can be provided at one side of the body 110. The connection jack 160 may be connected to an external power source to charge the battery accommodated in the body 110.
As shown in FIGS. 4 to 7, in such a clip type light 100 having the above structure, the cap visor 300 is positioned between the body 110 of the light 100 and the first and second clips 131 and 132. At this time, since the end portions of the first and second clip fixing sections 135 and 136 of the first and second clips 131 and 132 are bent upward, the light 100 can be easily coupled with the cap visor 300 if the user pushes the light 100 from the front side to the rear side of the cap visor 300. In addition, since both sides of the body 110 are curved downward while forming a curved surface, the body 110 can be closely coupled with the cap visor 300 having the curved configuration.
At this time, since the end portions of the first and second clip fixing sections 135 and 136 are bent upward relative to the upper surface of the cap visor 300, and the body 110 fully makes contact with the bottom surface of the cap visor 300 without requiring excessive force; the outer skin of the cap visor 300 may not be damaged by the first and second clips 131 and 132.
In the clip type light 100 attached to the cap visor 300, the rim of the cap visor 300 is fixedly inserted into the locking holes 131b and 132b formed at center portions of the first and second protrusions 131aand 132aof the first and second clips 131 and 132, and the first and second clips 131 and 132 are fixedly supported on the upper surface of the cap visor 300, so that the light 100 can be secured at the fixed position in the cap visor 300 without being separated from the cap visor 300, even if the user is involved in intensive activities, such as hiking or jogging.
In addition, as shown in FIGS. 6 and 7, in a state in which the clip type light 100 is fixedly attached to the cap visor 300, the front end portion of the cap visor 300 is positioned in the locking holes 131b and 132b of the first and second protrusions 131aand 132a, so the front portion of the cap visor 300 may protrude beyond the body 110 of the clip type light 100. Accordingly, raindrops falling on the upper surface of the cap visor 300 may be prevented from being introduced into the electric lamps 120 provided at the front portion of the body 110 of the light 100.
When it is necessary to operate the electric lamps 120 of the light 100 fixed to the cap visor 300 at night, the user simply pushes the switch 140 having the hemispherical shape, which protrudes from the bottom surface of the body 110 of the light 100, thereby operating the electric lamps 120.
In addition to the illumination function of the electric lamps 120, the electric lamps 120 may strobe or flicker in a predetermined time interval, if the user pushes the switch 140 one more time. This strobing function of the electric lamps 120 is very advantageous when the user is in emergency or when it is necessary to notify others of the position of the user.
Meanwhile, although it is not illustrated in figures, according to another embodiment of the present invention, a pair of switches 140 can be installed at both sides of the bottom surface of the body 110. In this case, one switch serves to operate the electric lamps 120 provided at the front portion of the body 110, and the other switch serves to operate the ultrasonic wave generator accommodated in the body 110 of the clip type light 100.
In addition, it is also possible to operate the ultrasonic wave generator accommodated in the body 110 of the clip type light 100 simultaneously with the electric lamps 120 by manipulating the switch 140 of the clip type light 100. In this case, ultrasonic waves are emitted through the ultrasonic wave ports 150 formed at the lower portion of the light body 110, thereby preventing insects, such as mosquitoes, from gathering in the vicinity of the electric lamps 120.
The ultrasonic wave ports 150 may include perforation holes, which are formed at the lower portion of the body 110 when the body 110 is fabricated through injection molding. In addition, the ultrasonic wave ports 150 can be formed at the lower portion of the body 110 after the body 110 has been fabricated.
Meanwhile, when the clip type light 100 of the present invention is not used, the user connects the connection jack 160 provided at one side of the body 110 to an external power source, such as a lighter socket installed in a vehicle, thereby charging the battery accommodated in the body 110 of the light 100. Thus, the user can use the clip type light 100 for a long period of time.
Hereinafter, the clip type light according to the second embodiment of the present invention will be described with reference to FIGS. 8 to 10. The same reference numerals will be used to refer to the same elements throughout the specification.

As shown in FIGS. 8 to 10, the solar cell plate 200 coupled with the clip type light 100 according to the second embodiment of the present invention includes a body 210, which is installed between a pair of clips 130. An extension member 220 is integrally formed with the front portion of the body 210. The extension member 220 has an arc-shaped section and power-supplying protrusions 230 are provided at both sides of the rear portion of the extension member 220 in such a manner that the power-supplying protrusions 230 can be inserted into the coupling holes 170 formed at both sides of the front portion of the body 110 to apply power to the battery accommodated in the body 210.
Preferably, as shown in FIG. 10, the solar cell plate 200 is positioned on the upper surface of the cap visor 300.
In the daytime, the clip type light according to the second embodiment of the present invention stores energy by absorbing solar heat through the solar cell plate 200, thereby charging the battery accommodated in the body 110 of the light 100. Thus, the user can use the light at night, without using an external power source.
In addition, although the present invention has been described in that the solar cell plate 200 is detachably coupled to the body 110 of the light 100, the solar cell plate 200 can be integrally formed with the body 110 of the light 100 or can be installed on the body 110 using a separate fixing unit.
Preferably, the solar cell plate has a large area to receive as much light from the sun as possible. To this end, the solar cell plate may have a foldable structure. In this case, the user may unfold the solar cell plate in daytime to receive solar energy and fold the foldable solar cell plate at night to easily store the foldable solar cell plate.
FIG. 11 is a perspective view showing a clip type light according to the third embodiment of the present invention, and FIG. 12 is a right-side view of FIG. 11.
The clip type light according to the third embodiment of the present invention is substantially identical to the clip type light according to the first embodiment of the present invention, except for the shape of the clip.
As shown in FIGS. 11 and 12, the clip type light according to the third embodiment of the present invention includes a clip section 400 coupled to the body 110 of the clip type light. The clip section 400 is provided with a head 410 having an arc-shaped section that protrudes upward in the front direction from the front portion of the body 110. First and second clip fixing sections 411 and 413 are provided at both sides of the head 410. The first and second clip fixing sections 411 and 413 extend along the upper surface of the body 110.
A locking hole 415 is defined by means of the head 410, and the rim of the cap visor 300 is fixedly inserted into the locking hole 415.
In addition, in order to allow the clip type light to be easily coupled with the cap visor 300, the center portions of the first and second clip fixing sections 411 and 413 closely make contact with the body 110 and end portions of the first and second clip fixing sections 411 and 413 which are bent upward from the upper surface of the cap visor 300.
Furthermore, since the front portion of the head 410 has a large surface area, the head 410 may serve as a billboard or a print board for exhibiting product names or advertisements.
As described above, according to the clip type light of the present invention, the body of the light is bent downward while forming the curved surface. In addition, first end portions of first and second clips are integrally formed with the body and second end portions of the first and second clips are elastically moved up and down, so that the cap visor is fixedly coupled with the first and second clips when the clip type light is attached to the cap visor. Therefore, the clip type light is easily attached to or detached from the cap visor while keeping the external appearance of the cap visor regardless of the various curved configurations of the cap visor; without causing damage to the outer skin of the cap visor; while preventing the light from moving or separating from the cap visor even if the user is in intensive activities.
In addition, the clip type light according to the present invention includes a switch provided at the lower portion of the light body in such a manner that the user can easily operate the electric lamp and the ultrasonic wave generator using the switch while wearing the cap equipped with the clip type light.
Furthermore, according to the present invention, the clip type light emits ultrasonic waves through the ultrasonic wave ports formed at the lower portion of the light body, thereby preventing winged or harmful insects, such as moths or mosquitoes, from gathering in the vicinity of the electric lamps of the clip type light.
Further, since the solar cell plate is provided on the body, the solar cell can be automatically charged in the outdoors during the daytime. In addition, the head part of the body may serve as a billboard or a print board for exhibiting product names or advertisements.
In addition, the clips provided at both upper sides of the light body are integrally formed with the light body, so that the clip type light has a secure and simple construction.
The invention is not intended to be limited to the preferred versions of the invention described above, but rather is intended to be limited only by the claims set out below.
