Description

Fluorescent lamp mechanism

The present invention relates to a fluorescent light fixture, and in particular, the PCB with the electronic ballast is fixed to the center of the body of the fluorescent light fixture without using a separate screw, and the lamp fixture that prevents the shaking or flow of the fluorescent lamp also does not use a screw. By being fixed to the body of the fluorescent light fixture, it is possible to increase the productivity by reducing the manufacturing and assembly process, and also to reduce the size (length) of the fluorescent light fixture.

In general, most indoor ceiling surface is equipped with a fluorescent lamp to illuminate the entire room by emitting light from the fluorescent lamp by the power applied from the outside.

Such a fluorescent lamp is usually a body having the shape of a long flat plate forming the frame of the main body along with the function of the reflector, and a lamp socket fixedly installed at both sides or the center of the body to be connected and supported by the terminal portion of the fluorescent lamp; It is composed of a socket cover formed in a shape surrounding the lamp socket, a ballast and a start lamp for supplying a stable current to the fluorescent lamp.

In addition, in the case of a fluorescent lamp having a lamp socket or ballast installed in the center of the body, a separate socket cover is detachably assembled to protect the lamp socket and ballast or to prevent them from being exposed to the outside. have.

However, a fluorescent lamp having a lamp socket or a ballast installed in the center of the body has a lot of inconvenience in the process of assembling and installing the fluorescent lamp body and the socket cover separately.

In order to solve the inconvenience, a fluorescent lamp having a fluorescent lamp body formed to cover the ballast and the lamp socket at the same time has been proposed.

The proposed fluorescent lamp body is a fluorescent lamp body provided with a rectangular space inside, and its center part is formed so as to protrude somewhat higher than the height of both sides, and the terminal formed in the fluorescent lamp is inserted or separated by the lamp socket formed therein. It is formed to be able to.

In addition, in the center of the fluorescent light fixture body is an electronic ballast which is lighter than the existing ballast and generates less heat is formed to extend its life.

In addition, the lamp fixtures are tightly fixed to surround the outer periphery of the fluorescent lamp in order to prevent the end of the fluorescent lamp inserted into the lamp socket from sagging or inclined due to its own weight.

However, since fluorescent lamps having electronic ballasts have lamp sockets formed at both ends of the PCB, the minimum space for the circuit elements is arranged on the PCB in the process of arranging the circuit elements to supply stable current to the fluorescent lamps. There was a problem that the length of the fluorescent lamp body is relatively long depending on the structural cause to be secured.

In addition, in order to fix the PCB with an electronic ballast to the inside of the fluorescent lamp fixture body with bolts, nuts or screws, a separate fixing hole is formed in the PCB, and a portion where the bolt and screw are inserted and fixed is formed inside the body. Due to the increase in the number of working processes in the process, there was a problem that is inefficient and inefficient.

In addition, when the fixing hole is formed in a relatively thin PCB and is too tight in the process of fastening with bolts or screws, the fixing part formed in the part of the PCB and the inside of the body is broken and worn, and thus cannot be used anymore. There was another problem.

The present invention has been devised to solve such a problem, a fluorescent lamp fixture for fixing the PCB and the socket having an electronic ballast to the body of the fluorescent lamp fixture without using a separate screw, and also prevents the shaking or flow of the fluorescent lamp Also, by fixing to the body of the fluorescent light fixture without using a screw, the purpose is to provide a fluorescent light fixture that can increase the productivity by reducing the manufacturing process and assembly process.
