In general, a lighting lamp is used to provide light or to irradiate an object to convert an electrical energy into light energy to identify an object indoors or outdoors at night, and recently, lighting is used to decorate an interior or to produce various colors. Generally, incandescent lamps, fluorescent lamps, halogen lamps, metal halide lamps, mercury lamps, and sodium lamps are used.

Fluorescent lamps are most commonly used as light sources in offices and homes, and have less glare and higher luminous efficiency, 1/3 of power consumption, and longer lifespans than incandescent bulbs.

In addition, compared to incandescent bulbs, there is an advantage that it hardly involves heat, and components such as fluorescent lamps and ballasts are separately configured, and fluorescent lamps apply fluorescent material to the inner wall of a vacuum glass tube (mercury discharge tube) and argon gas and A small amount of mercury is added and sealed, and a voltage is applied to generate light by the discharge of the gas.

Such a conventional fluorescent lamp is difficult to manufacture because the vacuum glass tube (mercury discharge tube) should be sufficiently sealed, and there is a problem that the straight tube lamp flickers when used for a long time, so that the user feels eye fatigue and increases the ambient temperature due to self heating. It causes power loss, does not turn on at a low voltage below the reference value, it takes a long time to turn on and emit light, and there is a disadvantage that the fluorescent lamp is broken when overheated.

Therefore, in order to solve these problems, the efficiency of converting power into light is high, the efficiency of light is higher than that of unit power, the lifetime is semi-permanent, and the power consumption is directly converted into electric energy. Intuitive lamps using LEDs (lighting emitting diodes), which can achieve high efficiency and low illumination, have been developed and are widely used in various applications.

In other words, LED straight lamps have the advantages of fast processing speed and low power consumption, and they are eco-friendly and energy-efficient because they do not use heavy metals such as mercury.
