Description

Quarter-bulb fluorescent lamps {ELECTRIC-LIGHT QUARTER BULB TYPE FLUORESCENT LAMP}

The present invention relates to a fluorescent lamp, and more particularly to a quarter-bulb 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 and three-wavelength fluorescent materials (rare earth powder) to improve their brightness, By producing near light, you can protect your eyesight and prolong the short lifespan of the incandescent 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.

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 bulb-type fluorescent lamp 10 is provided with a base 13, such as an incandescent bulb, unlike the conventional tubular fluorescent lamp 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.

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