The invention relates to an entertaining or promotional wearable device using a light source such as black light. In particular, a head gear with a brim or a visor having an area for marking with a fluorescent or phosphorescent paint and a plurality of ultra-violet light emitting diodes directed towards the area to illuminate the marking on the area to provide an entertaining effect or effective advertising.
Ultraviolet (UV) lights encompass lights having wavelengths of 4 to 400 nanometers. The longer wavelengths of the ultraviolet light spectrum are called black light, which have wavelengths slightly shorter than those that are normally visible and is generally safe for human viewing. Black light appears as a deep blue light because only a portion of the light has long enough wavelengths to be visible to human. For the purpose of this invention, blue black lights are simply called black light. An example of a shorter wavelength in the ultraviolet light spectrum is germicidal ultraviolet light that emits a much shorter wavelength that is dangerous to human skin and eyes.
The barely visible and invisible black light energizes fluorescent and/or phosphorescent pigments which then re-emits the light in visible colors. This results in the object appearing to have an independent glow as if internally lit. Black lights have been used as a source of illumination in theatrical productions, amusement park rides and home use for illuminating art covered with fluorescent and/or phosphorescent paint, and for general atmospheric effects for numerous years.
Traditionally, a black light source is generally a tube, similar to a fluorescent tube that produces white light, of a certain length. Traditional black light source is not conveniently portable due to the size and the need of either alternating current or large voltage direct current. While black light has been used to illuminate all sorts of fluorescent or phosphorescent objects, black light as a portable device has been used only more recently. Using light emitting diodes (LEDs) that can produce UV black lights (generally known as UV LED, portable black light devices are developed. UV LEDs are similarly sized as typical prior art LEDs and can be powered by direct current such as batteries.
The inventor's prior “Portable Black Light Device” using UV LEDs is disclosed in U.S. Pat. No. 6,969,178. The ‘178 patent is a head gear having UV LEDs directed towards and illuminate the wearer's face or the upper portion of the head gear having fluorescent or phosphorescent elements thereon.
Other head gears that provide entertaining values are disclosed in U.S. Pat. Nos. D448,527, D287,061, D283,749, and D283,268. These prior art head gears disclose holders attached to the head gears for receiving beverage cans and straws are incorporated into the head gear for insertion into the beverage cans such that a wearer can consume the beverage while the cans are held in the holders.
The present invention provides a head gear that has an area for marking with a fluorescent or phosphorescent paint and a plurality of ultra-violet light emitting diodes directed towards the area to illuminate the marking on the area to provide an entertaining effect or effective advertising.
The head gear of the present invention comprises a main body and an attached visor body having am upper portion and a lower portion. The main body fits over or on a wearer's head. The upper portion of the visor body is pivotably attached to the lower portion. The upper portion has an area for receiving markings, and at the outer perimeter of the area is a plurality of UV LEDs directed towards the area to adequately illuminate the entire area. In an open position, the upper portion is at a substantially right angle, vertical position, relative to the lower portion such that the area is displayed to a viewer in a forward position. In a closed position, the area is hidden and the upper and lower portions form the visor of the head gear. The power source and electronic circuitry for powering and controlling the UV LEDs are contained in the visor body.
When in use, the upper portion is in the open position and a fluorescent or phosphorescent marker is used to make markings on the area. With the UV LEDs turned on, the markings on the area will glow brightly, as if internally lit. The area allows any marking thereon to be easily erased for infinite displays and variations.
In a preferred embodiment, the head gear additionally comprises two holders attached to the main body for receiving two beverage cans and two markers, and straws for insertion into the beverage cans. This embodiment further increases the entertaining and promotional values of the head gear.
Preferred embodiments of the present invention have been chosen for purposes of illustration and description and are shown in the accompanying drawings forming a part of the specification wherein:
With reference to the drawings, wherein the same reference number indicates the same element throughout, there is shown in
As shown in
Attached to the main body 20 is the visor body 50, which extends from the main body 20 in a substantially horizontal plane. The visor body 50 comprises an upper portion 52 and a lower portion 54 that are hingedly or pivotally attached to each other. On the inner surface of the upper portion 52 opposing the lower portion 54 is a depression 56. At the base of the depression 56 is an area 58 for receiving markings. At the perimeter of the area 58, along the wall of the depression 56 are a plurality of LEDs 60 (such as UV LEDs) directed towards the area 58. Other light source (with or without the need of electrical power), such as chemiluminescent element, glow-in-the-dark element, electroluminescence panel, incandescent bulb, fiber optics, etc. can be used instead of LEDs 60. The upper portion 52 also houses the power source, such as batteries (not shown), and electrical circuitry 64 that control the LEDs 60. A control switch 62 is provided on the upper portion 52 to control the LEDs 60. The plurality of LEDs 60 may be turned on (simultaneously, sequentially or at random), blink/flash (simultaneously, sequentially or at random), individually turned on/off sequentially (i.e. chasing/animation), or fading in and out (simultaneously, sequentially or at random). Different sequences in turning on and off the plurality of LEDs 60 can be programmed into the electrical circuitry 64 as known to one skilled in the art.
The area 58 may contain a removable sheet of paper, a white board or a black board that is made of a magnetizable or plastic material. Other types of material or surface can be used in area 58 as long as markings can be received thereon. Preferably, the area 58 allows markings to be easily erased for infinite variations of markings to be displayed. If the area contains a white or black board, tissues can be used to easily wipe off the markings. To provide maximum entertaining value and effective advertising, the markings can be made with fluorescent or phosphorescent paint such that the markings appear to be internally lit in response to the UV LEDs 60. Additional two- or three-dimensional fluorescent or phosphorescent elements (such as stickers, sculptures) may be provided for a user to attach them to area 58 by any fastening means known to one skilled in the art, such as adhesive, magnet, Velcro®, hook and loop, etc. for even more entertaining value and effective advertising.
When the visor body 50 is in the open position (as in
