FIG. 1 is a perspective view of an LED lighting apparatus according to the present invention, and FIG. 2 is an exploded perspective view of the LED lighting apparatus of FIG. 1. FIG. 3 and FIG. 4 are perspective views of a circuit board schematically showing the first and second light emitting units in the LED lighting apparatus according to the present invention.

Here, the DC-dedicated LED lighting apparatus will be mainly described with reference to FIGS. 1 and 2. FIG.

On the other hand, the AC-dedicated LED lighting device has the same configuration except that it has a power connection portion inserted into the socket instead of the inner cap.

1 to 4, the LED lighting apparatus 100 according to the present invention includes a DC power jack 110, a switching unit 120, a charger 130, first and second light emitting units 140 and 140, The outer cap 180, the diffusion cover 190, the lens 200, and the iron plate 210, as shown in FIG.

The DC power jack 110 is a portion to which an external DC power source is applied, and a general adapter type jack is inserted to supply DC power.

Here, the DC power source is supplied from an energy storage device (not shown), which is an apparatus for storing electricity produced from a power generation device such as solar power or hydroelectric power.

The DC power supplied through the DC power jack 110 lights up the first light emitting unit 140 and the charging unit 130 is charged. The DC power supplied through the DC power jack 110 Power can be simultaneously supplied to the first light emitting unit 140 and the charging unit 130 so that lighting and charging can be performed.

The DC power supplied through the DC power jack 110 may illuminate only the first light emitting unit 140 and may be supplied to the charging unit 130 when the first light emitting unit 140 is not turned on, .

A through hole is formed in the DC power jack 110. The through hole is formed to correspond to a through hole formed in the inner cap 170, and a DC jack is inserted to supply DC power.

The switching unit 120 selectively controls ON or OFF of the first and second light emitting units 140 and 150. The first light emitting unit 140 is turned on and the second light emitting unit 150 is turned off through the DC power supplied from the DC power jack 110. [

On the contrary, when the flash unit is used as a flash unit when going out at night, the first light emitting unit 140 is turned off and only the second light emitting unit 150 is turned on.

The first light emitting unit 140 may be turned on only through the power source stored in the charging unit 130 when the user goes out at night. However, since the brightness of the first light emitting unit 140 is greater than that of the second light emitting unit 150 It is preferable to use the second light emitting portion 150 because the second light emitting portion 150 is deteriorated and the linearity is deteriorated.
