Description

Bulb-type fluorescent lamp {ELECTRIC-LIGHT BULB TYPE FLUORESCENT LAMP}

The present invention relates to a fluorescent lamp, and more particularly to a bulb-type fluorescent lamp that forms the shape of the discharge tube in a circular bulb shape.

In general, bulb-type fluorescent lamps are widely used as home and office lighting fixtures, replacing the incandescent lamps used for conventional lighting, and use energy-saving fluorescent lamps of three wavelength fluorescent materials (rare earth powder) to improve their brightness. Of course, by directing light close to natural light, it can protect eyesight and extend the short lifespan of the incandescent light bulb. Recently, various technical developments have been made and practically used to satisfy all conditions of incandescent lamps.

In addition, the bulb-type fluorescent lamp described above is configured to be applied to the socket used as the conventional incandescent lamp.

1 is a perspective view of a conventional bulb-type fluorescent lamp.

As shown in FIG. 1, the conventional bulb-type fluorescent lamp 10 is formed of a discharge tube 11, which is a light emitter, a ballast 12 and a spiral structure for supplying power for lighting the discharge tube 11, and a socket. It consists of the base 13 provided with 14. On the other hand, the fluorescent lamp 10 is provided with a base (3) such as an incandescent bulb, unlike the conventional fluorescent tube is used to fit in the socket. In this case, unlike the incandescent bulb 10, the bulb type fluorescent lamp 10 requires a ballast 12 which induces a start voltage at the time of lighting. Therefore, the bulb type fluorescent lamp 10 inserted into the socket 14 is used as a ballast ( 12 is provided between the base 13 and the discharge tube 11.

Looking at the operation of the bulb-type fluorescent lamp, when the power is applied to the ballast 12 electrically connected to it through the socket 14, the characteristics of the fluorescent lamp induces a start voltage in the ballast 12 to the discharge tube 11 The electrons are emitted by the voltage applied to the discharge tube 11 and collide with the fluorescent material applied inside the discharge tube 11 to generate light.

However, the conventional bulb-type fluorescent lamp has a problem that the shape of the discharge tube is bent in a straight tube U-shaped because the discharge tube shape is formed in a cylindrical rather than a circular shape does not give an aesthetic sense.

In addition, in order to solve the above problems, the discharge tube may be inserted into the outer glass tube of the bulb type, but this also has a problem in that the manufacturing method is difficult and the manufacturing cost is relatively increased.

Therefore, an object of the present invention is to solve the above problems, to provide a circular bulb-type fluorescent lamp that can provide aesthetics while having a relatively low manufacturing cost by forming the discharge tube shape in a circular bulb shape.

2 to 5, the bulb type fluorescent lamp 100 according to the present invention includes a discharge tube 110, a ballast 120, and a base 130.

The discharge tube 110 is composed of a first discharge tube 111, a second discharge tube 114, and discharge path forming means 117.

The first discharge tube 111 is formed in a hemispherical shape in which a fluorescent material is applied therein, one end of which is extended and an electrode 112 is formed at an end thereof, and a plane 113 is formed on one surface thereof.

The second discharge tube 114 is formed in a hemispherical shape in which a fluorescent material is coated therein, one end of which is extended to form an electrode 115 at an end thereof, and a plane 116 is formed on one surface thereof. In this case, the first discharge tube 111 and the second discharge tube 114 are horizontal with each plane 113 and 116 being symmetrical. In this case, the first discharge tube 111 and the second discharge tube 114 maintain the symmetrical shapes of the planes 113 and 116 and deform to any shape (for example, a candle shape or an eight-character shape). It is possible.

The discharge furnace forming means 117 is formed in a hollow pipe shape and a fluorescent material is coated therein, and is bonded between the first discharge tube 111 and the second discharge tube 114 to form the first discharge tube 111 and the second discharge line. A discharge path is formed between the discharge tubes 114. Here, the discharge path forming means 117 cuts and processes a pipe-shaped protrusion that rises when it is drilled by applying heat to the same positions of the planes 113 and 116 of the first discharge tube 111 and the second discharge tube 114. It is then formed by bonding. Here, the discharge path forming means 117 can also be produced by attaching a separate pipe-shaped glass tube.

The ballast 120 is electrically connected to the electrodes 112 and 115 for supplying power to the first discharge tube 111 and the second discharge tube 114, and supplies power to the inside of the base 130 to be described below. It is inserted and electrically connected to the socket 131.

First, the manufacturing process of the bulb-type fluorescent lamp according to the present invention, the socket 131 is attached, the first discharge tube 111 and the second in the state prepared with the base 130 in which the ballast 120 is inserted therein After the planes 113 and 116 of the discharge tube 114 are horizontal, they are joined to the discharge path forming means 117, and then the electrodes 112 are formed at each end of the first discharge tube 111 and the second discharge tube 114. , 115). Then, the ballast 120 and the electrodes 112 and 115 are electrically connected to each other, and the first discharge tube 111 and the second discharge tube 114 are adhesively fixed to the base 130.

When the socket 131 of the bulb-shaped fluorescent lamp 100 completed as described above is inserted into a socket for purchasing a bulb (not shown), power is supplied to the ballast 120 through the socket 131, and by the ballast 120. The discharge path leading to the first discharge tube 111 and the discharge path forming means 117 and the second discharge tube 114 is applied to the electrodes 112 and 115 of the first discharge tube 111 and the second discharge tube 114. Formed and electrons are emitted. Due to the emission of electrons, the fluorescent material applied to the first discharge tube 111 and the second discharge tube 114 is excited to generate light.
