Description

Glass with lighting

Technical field

The technical solution relates to a glass, in the bottom of which there is an electric circuit with a light source, which enables to illuminate the contents of the glass.

BACKGROUND OF THE INVENTION

Drinking glasses, goblets and cups that are provided with lighting equipment are known from a number of documents. For example, a beverage cup is known from patent application WO 96/24007, in which a chemiluminescent bar is disposed in the hollow foot which enables the beverage to be illuminated in the cup. The hollow leg, the cup stand and the cup itself are separable from each other, which allows the chemiluminescent bar to be replaced at any time, and at the same time is desirable from a hygienic point of view, as this allows the chemiluminescent light source to be completely separated. This substantially eliminates the disadvantage of the beverage cup with a hollow leg for the lighting device of U.S. Pat. No. 4,563,726. The lighting device of this patent is formed of a flexible tube, closed at both ends. Inside the tube are separately sealed two substances, one of them in a separate glass ampoule. By bending the flexible tube, the glass ampoule is disrupted, the two substances are mixed, thereby activating the chemiluminescent reaction with subsequent cold light emission, which irradiates the beverage in the cup. A beverage glass with decorative lighting is also described in U.S. Pat. No. 5,119,279. The glass of this patent consists of a pedestal with LEDs and a liquid-tight cup detachably connected to the pedestal. The liquid-tight cup also comprises a power source, wherein in the connected state of the cup stand, the power source is conductively connected to an electrical circuit placed in the pedestal, to which besides the LEDs located on the pedestal periphery also . Another device intended for illuminating beverages in a glass, suitable for various social events, is the subject of U.S. Pat. No. 4,344,113. The container of the present invention is again comprised of a glass and a pedestal containing a light source as a light source, a disposable electric current source. or a rechargeable battery, associated electrical connections, and resilient electrical contacts that allow, in the assembled state of the base and the glass, the bulb to emit light to illuminate the beverage in the glass. To enhance the decorative effect, the bulb can be formed as a glass lens, thereby focusing or amplifying the luminous flux into the beverage. Another device for illuminating the contents of a glass or goblet with a beverage is disclosed in U.S. Patent 5,211,699. In one embodiment of the patent, the lighting device is disposed in a hollow cup of the goblet and consists of a power source, LED and associated electronic elements. in the cup leg in which the lighting device is located, it is closable by means of a plug.

As a rule, said electric lighting devices also comprise a mechanical switch as part of the electrical circuit, allowing interruption of the electrical circuit and thus prolonging the life of the source. In contrast to such a solution, the two-piece glass according to U.S. Pat. No. 4,922,355, which is two-piece and consists of a bottom with a light source and a top for a liquid, does not include a mechanical switch but a contact set that closes the electrical circuit Only when the upper part is filled with a beverage, or only when a person holds the glass in his fingers. Drinking or traces of sweat on the skin of the toes reduces the resistance of the circuit to such an extent that the light source comes on.

The essence of the technical solution

The illuminated glass according to the present invention has a recess in the bottom having a removable closure provided with an electrical circuit comprising a power source, at least one LED and associated electronic elements, wherein an optical dispersion element, e.g. optical prism or holographic prism

-1 CZ 13128 Ul plate. On the lower outer surface of the closure there are two contacts separated by a narrow gap.

Preferably, the removable closure and recess in the bottom of the glass is threaded. The closure may be made of glass, but preferably will be of plastic. It can be transparent and clear, translucent or completely opaque.

The optical dispersion element may be a holographic plate, an optical prism or an optical fiber bundle.

If the glass is cup-shaped, the LED can be placed in the foot.

BRIEF DESCRIPTION OF THE DRAWINGS

Figure 1 is a schematic side view of a glass with lighting according to the invention.

Figure 2 is a side view of the closure.

Figure 3 is a bottom view of the closure.

Figures 4 and 5 show a top view of the closure and at the same time one variant of the electrical circuit.

Examples

The illuminated glass of Figure 1 has a threaded recess 1 in the bottom, with a holographic plate 2 positioned above the recess 1 in the glass. The recess 1 is a threaded closure 9 and furthermore an electrical circuit with LED 4 in which it is a source Due to the use of the LED, the electrical circuit also includes the associated electronics 8. The electrical circuit is located on the printed circuit board 7.

As can be seen from Figure 3, the lower outer surface of the closure 9 is provided with two contacts 5 between which there is a narrow gap. Wells 6 are also provided in the lower outer surface for receiving a tool for screwing or unscrewing the closure 9 into the recesses in the bottom of the glass.

In Figure 4, the closure 9 is seen from above. On the circuit board 7 is placed a power source 3, LED 4 and associated electronics 8, which in this case comprises two SMD resistors and an SMD transistor. The wiring diagram including the two electrical contacts 5 on the underside of the closure 9 is shown in Figure 5.

The LEDs located in the cap can emit light of different colors and intensities, at different beam angles. They can be placed anywhere in the closure in any color and number, limited only by the size of the closure. However, they do not have to be placed only in this closure, but can be pulled into the glass leg, for example. In this case, only one LED will be placed in the glass leg.

Optical elements of different character can be placed in the glass above the LEDs, which can, for example, refract the emitted light and thus create light patterns or other light effects in the glass. For example, a polyhedral glass prism or a hologram plate can be placed above the light source, through which a spatial image will be displayed in the drink, for example the name of the bar. Interesting light effects can also produce optical fibers adjacent to the light source and optically resulting in suitable places into the beverage inside the glass or vice versa towards the walls of the glass.

The closure may also be of any color, transparent, translucent or completely opaque. Advantageously, the closure may be formed of plastic. If the contacts on the underside of the closure are wetted, electric current is transferred between the two contacts and the LEDs light up. After evaporating or drying the liquid from the contact pad, the LEDs turn off.

Electronics can be solved in several ways, using various components. The basic circuit contains two SMD resistors and one SMD transistor. The LED can be either in a standard housing or also in SMD design. The diode can be powered by any miniature battery with sufficient voltage and capacity. Most often a 6 V or 12 V alkaline battery is used. The electronics may also include additional components that provide such electrical circuit functions as flicker, LED color change depending on the temperature of the drink, or other light or sound effects.
