Abstract

The present invention relates to the structure of a light bulb that can achieve the original purpose while reducing power consumption and extending the life by changing the structure and materials of the light bulb used as the guide light for emergency passage or night security lamp.

Light bulbs for lighting or induction lamps that are commonly used have the advantage of being light by flowing current through the filament, but they have to be replaced frequently because they consume a lot of power, generate a lot of heat, and have a short lifespan. Using a kind of visible light emitting device (LED) can significantly reduce heat generation while significantly lowering power consumption, which greatly increases the lifespan.

The core of the present invention is to configure an electric circuit (FIG. 6) so that the visible light emitting device, which is a kind of semiconductor, emits light when a direct current is supplied, can be directly used in general AC power. In addition, to improve the workability in the mass production of the light bulb according to the present invention, the circuit configuration of the substrate (Fig. 7) is also important.

The light bulb for emergency guidance light according to the present invention has the advantage of low power consumption and long life, and it can be effectively carried out to reduce the cost and achieve its original purpose if it is installed in a relatively neglected tunnel or a corridor of a basement.

Description

Emergency induction light bulb using visible light emitting element {Made an Emergency Guide Lamp with LED}

The present invention relates to the structure of a light bulb that can achieve the original purpose while reducing power consumption and extending the life by changing the structure and materials of the light bulb used as the guide light for emergency passage or night security lamp.

Normally used lighting bulbs or induction bulbs generate light by flowing current through the filament, but they have the advantage of being bright, but they have to be replaced frequently because they consume a lot of power, generate heat and have a short lifespan.

(Fluorescent lamps consume less power and have a longer lifespan than light bulbs, but are bulky and expensive because they require separate accessories such as ballasts and glow starters.)

In order to compensate for this, if a light guide diode (LED: Light Emitting Diode) is used as a light semiconductor instead of a filament to make a guide light bulb, the power consumption can be significantly reduced and the heat generation can be substantially reduced, and the life is greatly reduced. It also extends and can optionally use up to six types of light.

Therefore, the object of the present invention is to significantly reduce the maintenance costs and improve safety by greatly extending the lifespan of emergency light bulbs installed outdoors, emergency underground passages of buildings, emergency passages of buildings, and emergency guide lights for fire fighting.

In order to achieve the above object, the present invention uses a visible light emitting device as a light emitting device instead of a filament of a light bulb. In order to flow a current through the visible light emitting device, the visible light emitting devices (1) and (1) 'must be arranged in parallel and parallel form on both sides of the substrate ((2) (2)') as shown in FIG. Therefore, in order to protect against electric shock and overcurrent applied to the rectifying diode ((3) (3) ') and the visible light emitting element ((1) (1)') that converts alternating current into direct current ((4) (4) ') Is placed on the same substrate. The substrates ((2) (2) ') have two electrodes (11) (11)' on the substrate so that they can be supplied with power. Connection) is electrically connected to the inner electrode (two of the sockets ((Fig. 2) and Fig. 4)) and is alternating and irrespective of polarity) and to prevent the substrate 2 from bending or shaking. It is fixed with an adhesive (Fig. 1 (9): α-cyanoacrylate type) as the end of the glass tube (5), or the plastic tube (6) is made by forming a groove (Fig. 3 (10)) in the tube itself. To be supported.

The glass tube 5 of FIG. 1 is resistant to heat but easily broken when dropped, and the plastic tube 6 of FIG. 3 is weak to heat but relatively strong against external impact and easy to manufacture.

The socket 7 of FIG. 1 is rotatable like a normal light bulb, and the socket 8 of FIG. 3 has a glow starter type so that attachment and detachment are easy even with small rotations.

That is, Figure 1 (including Figure 3) in the present invention is applied to the form of a general electric bulb can be used directly in the existing electrical facilities, but the connection of the substrate and the socket ((7) (8)), the socket 7 and the glass tube ( 5) has a disadvantage in that the manufacturing cost is high because the connection is rather complicated.

FIG. 3 (including FIG. 4) simplifies the socket 8 and employs a plastic tube 6 by injection molding instead of the glass tube 5 to facilitate manufacturing, but has a disadvantage in being weak in heat.

The present invention uses a semiconductor and an optical semiconductor as a material, so as to obtain light, the current used must be a direct current. However, since the current generally used is an alternating current, an electric circuit is configured to be used directly in an alternating current based on a 220V voltage. Normally, the bridge circuit is configured and converted to direct current, but the light bulbs such as emergency induction lamps are small, and thus a bridge circuit cannot be built in, thus configuring a circuit as shown in FIG. 6.

The general electricity of Korea is 220V / 60Hz, so the pole changes 60 times per second.

Therefore, if two circuits having different poles in series are arranged in parallel on one side of the substrate ((2) (2) '), the alternating current will emit only one circuit of the same pole each time the pole changes. That is, five visible light emitting elements (1) (1) 'are lit on one surface of the substrate ((2) (2)'). In reality, however, everyone seems to be lit up like a fluorescent lamp by the afterimage effect.

The visible light emitting device (LED) used in the present invention is an optical semiconductor made of a compound semiconductor as a basic material, and currently realizes six colors (red, green, blue, yellow, orange, white) and has a luminance of up to 8000 mcd. There is a product. Therefore, since 20 visible light emitting elements are used in a light bulb, there is no problem in brightness, and it satisfies the original purpose sufficiently as it is mainly used as a guide light in a dark place, not for lighting. In addition, optical semiconductors operate at low voltage and low current because of low power consumption, and emit light.

The emergency guide light bulb according to the present invention has a low power consumption (1/20 of a general light bulb) and has a lifespan of 50 times that of a general light bulb. Achieve original goals more effectively. Especially in the case of emergency guidance lamps, the effect of long lifespan is greater because it is on for 24 hours.
