Description

  The present invention relates to a lighting device, and more particularly to an LED bulb.

  Due to its small volume, low driving voltage, fast reaction speed, high earthquake resistance, long life, and environmental friendliness, LEDs have recently been widely applied to lighting devices instead of traditional light sources. It has come to be.

  With the continuous development and advancement of technology, the luminous efficiency of LEDs has surpassed that of incandescent lamps and is now trying to surpass fluorescent lamps. In addition to this, in the field of electronic components that require "light, thin and compact", LED bulbs are gradually being replaced by incandescent lamps, and they are used in large quantities and widely. A conventional LED bulb includes a bulb head, a power circuit board assembly, a light-emitting heat dissipation unit, and a lamp shade. Electrical connection is made between the light bulb head and the power supply circuit board assembly, and between the power supply circuit board assembly and the light-emitting and heat-dissipating unit by welding the conductive wires or pressing the conductive wires using screws.

On the other hand, since the internal space of the lighting fixture is small, the internal temperature tends to increase during use. In this situation, if a long conducting wire is pushed into the lighting fixture as much as possible, phenomena such as breakage of the conducting wire, wobbling or falling off of the welding point of the conducting wire, and loosening of the pressure fixing of the screw to the conducting conductor are likely to occur. As a result, short-circuiting, disconnection, and instability of lighting may be caused. In serious cases, the lighting device may burn and be damaged, and an accident such as electric leakage may occur.
