Description

Light bulb {Lamp}

The present invention relates to a light bulb, and more particularly to a light bulb having a base structure capable of normal operation in combination with the socket conveniently and quickly.

In general, there are two ways to get light from a lamp. One is to emit light by the release of heat, and the other is to obtain light by gas discharge.

For convenience of description, the incandescent bulb will be described in detail as an example.

Incandescent lamps (incandescent lamp) is a light bulb that emits light as heat is generated by the resistance of the filament (filament).

Incandescent bulbs have tungsten filaments embedded in vacuum or gas-filled glass spheres. The gas contained in the glass sphere raises the temperature of the tungsten filament and reduces evaporation. The encapsulation gas of an incandescent bulb measures the luminous flux efficiency (the luminous flux is a measure of the amount of light energy passing through a plane in a unit of time on the basis of the sensitivity of the eye to the observer's eye. The unit uses lumens [lm].) It prevents the fall of luminous flux by raising and preventing blackening in the glass sphere (the inside of the glass sphere turns black due to instantaneous lighting). The luminous flux efficiency can be further improved by increasing the number of times the coil is wound around the filament.

1 is a view showing the configuration and shape of a conventional incandescent light bulb.

Referring to FIG. 1, an incandescent bulb includes a filament 110, a lead line 120, a glass sphere 130, an anchor 140, and a base 150.

As the filament 110 has a higher lighting temperature, the ratio of visible light emitted is increased, thereby improving the efficiency of the bulb. Therefore, the material used as the filament is preferably a high melting point. And it should not evaporate as high as possible at high temperatures. Metals that tend to evaporate at high temperatures evaporate molecules from the surface of the metal during lighting, resulting in thinning of the filaments, and blackening occurs due to evaporation metal molecules attached to the inner walls of the glass spheres 130, thereby causing decay of the luminous flux. Tungsten is widely used as a filament for bulbs because it has a high melting point of 3,410 degrees Celsius, low evaporation, and free processing to fine lines.

In the early stages of the bulb, straight filaments were used in vacuum, but coils were used to reduce evaporation or heat loss due to conduction convection of the enclosed gas. When used in the form of a double coil, the efficiency is better and the dimensions of the light source are smaller.

Lead line 120 is a member for transmitting electrical energy to filament 110.

Glass sphere 130 generally uses lead glass or soft soda lime glass as a material. In addition, in order to reduce the brightness of the bulb (a measure of the contrast of the object surface and the glare of the light source) to be suitable for lighting, it is frosted using fluorine compounds (FO, NH_4F) on the inner surface of the glass sphere, or used as a milky white bulb. Silica powder is coated on the inner surface to increase the diffusion surface of light.

In addition, the glass tube 130 may be filled with an inert gas to suppress evaporation of tungsten and to design a high filament temperature.

The encapsulation gas generally uses nitrogen (N 2) and argon (Ar), and argon is heavy in molecules, has a large evaporation inhibiting effect, and has a low heat loss but is easy to cause discharge. The higher the purity of argon and the higher the encapsulated gas pressure, the higher the efficiency.

The anchor 140 is required for heat resistance and shock resistance as a support of the filament, usually molybdenum wire, sometimes tungsten is used.

The base 150 has a thread-shaped bend to allow the incandescent bulb to be coupled with the socket, and is coupled to the lead line 140 to transmit electric energy introduced from the outside to the filament 110.

In the past, brass was used as the base material. However, in consideration of mechanical strength and corrosion resistance, aluminum alloy is used a lot now.

2 is a view showing a shape in which a conventional incandescent bulb is combined with a socket.

Referring to FIG. 2, the user holds the incandescent bulb 210 with his right hand and rotates it in a counter clockwise direction (see an arrow in FIG. 2), and configures the base of the incandescent bulb 210. The engagement cross section of the state combined with the socket | bulb 220 for incandescent bulbs using the screw thread shown is shown.

In addition, the user can rotate the incandescent bulb 210 in a clockwise direction in order to separate the incandescent bulb 210 from the socket 220.

However, conventional light bulbs are inconvenient for the user to rotate the bulb a certain number of times in order to couple and disconnect the bulb from the socket.

In addition, even if the glass bulb of the bulb is broken, there is a problem that the user may suffer accidental damage by requiring a certain number of rotations (in the opposite direction to the coupling direction) to separate the bulb coupled to the socket.

Accordingly, it is an object of the present invention to provide a light bulb that can be combined by simply pushing the light bulb into the socket in order for the user to combine and disconnect the light bulb from the socket, and can be detached by a pulling operation.

Another object of the present invention is a bulb that can be separated from the socket by simply pulling a tool using a tool that can be fixed by holding the base portion of the bulb in case the glass bulb of the bulb is broken to promote the safety of the user To provide.

Still another object of the present invention is to provide a light bulb that can be combined by a method of simply pushing a light bulb into the socket even by using a conventional light bulb socket, and detachable by a pulling operation.
