Description

Fluorescent lamp type LED lamp {LED lamp type fluorescent lamp}

The present invention relates to a lighting lamp, and more particularly, to an LED lamp that can be used in a fluorescent lamp having an existing ballast.

That is, the leakage current generated inside the LED lamp can be minimized, and it can be applied to a fluorescent lamp socket that is already installed, and can be used as it is, but the LED lamp improves the durability of both ends of the lamp and improves the productivity. It is about.

Compared to incandescent bulbs, there is less glare, high luminous efficiency, and long life, so one of the lighting fixtures used is fluorescent lamp. This fluorescent lamp uses light from gas or gas discharge as a light source. A small amount of mercury vapor and argon gas for easy discharge are sealed in a vacuum glass tube, and then electrodes are attached to both ends.

The fluorescent lamp thus constructed has a high efficiency due to less loss due to heat and a long lifespan. Such a fluorescent lamp is a kind of mercury discharge tube having negative resistance characteristics. When the power supply is only supplied, the fluorescent lamp is provided with a ballast to induce lighting and stably supply power after the lighting. That is, a ballast was installed to initially apply a high voltage to start discharge required for lighting a fluorescent lamp, and then to provide a stable voltage and current.

Fluorescent lamps configured as described above are constructed using a vacuum glass tube as described above, so that the manufacturing of the vacuum glass tube should be sufficiently sealed during manufacture, and there are many difficulties in manufacturing, and there is a case in which the lamp does not suddenly turn on and flickers when the life is near. The street had a problem. In addition, since the light generated by the conventional fluorescent lamp includes ultraviolet light that fades or deteriorates, there is a problem of deteriorating food when used in a refrigerator or the like.
