Description

Flat fluorescent lamp {ELECTRIC-LIGHT FLAT TYPE FLUORESCENT LAMP}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fluorescent lamp, and more particularly, to a flat fluorescent lamp that can form a rectangular shape of a discharge tube to give a user a sense of beauty and expect a display effect.

In general, the bulb-type fluorescent lamp is widely used as a home and office lighting fixtures replacing the incandescent bulbs used as conventional lighting, and it uses energy saving three-wavelength fluorescent substance (rare earth powder) and improves the brightness of natural light. 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 conventional bulb-type fluorescent lamp, when the power is applied to the ballast 12 is electrically connected to it through the socket 14, the discharge tube 11 by inducing the start voltage in the ballast 12 due to the characteristics of the fluorescent lamp ), And 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.

Accordingly, an object of the present invention is to solve the above problems, and to provide a flat fluorescent lamp that can provide aesthetics and display effect while having a relatively low manufacturing cost by forming a discharge tube in a rectangular shape. .
