Description

Bulb Type Fluorescent Lamp Provide With Ballast Stabilizer Cooling Means}

The present invention relates to a bulb-type fluorescent lamp with a built-in ballast, and more particularly, by dissipating heat generated inside the ballast to the outside by a forced convection method to prevent thermal damage to the ballast element to extend the life of the fluorescent lamp, The present invention relates to a bulb-type fluorescent lamp equipped with a ballast cooling means to stably implement a high-power fluorescent lamp.

In general, the bulb-type fluorescent lamp is a conventional fluorescent lamp in the form of an incandescent bulb, so-called three-wavelength fluorescent lamp. Such bulb-type fluorescent lamps have an electronic ballast in a housing having a socket coupling part for power connection, and have one or more linear lamps (linear lamps) in the housing, or ends of two linear discharge paths. Is connected to one or more lamps having a ring shape or horseshoe shape (ring lamp), or one or more lamps bent in a U-shape (U-tubular lamp), Alternatively, two lamps are provided in a structure in which lamps of various structures are installed, such as a shape having spirally twisted lamps (spiral lamps) in which two lamps have ends connected.

In recent years, the demand for high brightness of fluorescent lamps has been increasing year by year. Among the various methods, the lamp with high power stabilizer built-in is a promising method for realizing high brightness fluorescent lamp because it requires less power and has a longer lifetime than the brightness. Has been considered.

However, when the required power rises to obtain high brightness, the heat generated from the filament that is applied to the lamp also increases. Usually, in the case of a fluorescent lamp with a ballast, the filament of the lamp is located inside the ballast housing, so Due to the heat generated, the temperature inside the housing is excessively increased, which causes damage to elements of the ballast, such as a capacitor and a transistor. Therefore, as the required power increases, the life of the ballast is shortened. Therefore, the implementation of the fluorescent lamp using the high power of 30W or more was not achieved.

The present invention devised in view of the above, by forcibly circulating and cooling the outside air into the ballast housing to extend the life of the heat-resistant ballast elements to extend the life of the fluorescent lamp as a whole, accordingly high power fluorescence It is an object of the present invention to provide a bulb-type fluorescent lamp equipped with a ballast cooling means of a structure so that the lamp can be stably implemented.
