In addition, the present invention provides a lighting device having a heat transfer path capable of rapidly transferring heat to the base side when the power module is ignited.

For this, the insulation part 152 may be formed of a material having a lower melting point than the melting point of the housing 110.

That is, when the power module 130 is ignited, the peripheral area of the power module 130 is increased to a predetermined temperature or more, and the housing 110 does not reach the melting point at a predetermined temperature, And the insulating portion 152 is gradually melted.

In this case, the melting point of the insulation part 152 may be less than the melting point of the housing 110. In this case, the melting point of the insulation part 152 may be 20 Deg.] C to 60 [deg.] C.

For example, when the housing 110 is formed of a PPS material, it has a melting point of about 310 ° C to 340 ° C. When the insulating portion 152 is formed of a PC material, Of melting point.

The insulating part 152 is provided between the first electrode part 151 and the second electrode part 153 connected to the external power source and the first electrode part 151 and the second electrode part 153 Insulation. In general, the first electrode unit 151 and the second electrode unit 153 are formed of a metal material.

Accordingly, when the insulating portion 152 is melted, the interval between the first electrode portion 151 and the second electrode portion 153 changes. The first electrode unit 151 and the second electrode unit 153 may be electrically connected to each other in the lighting space of the lighting apparatus 100. In this case, As shown in Fig.

5 and 6, the base 150 is detachably mounted to a power socket 300 connected to an external power source. Reference numeral 310 denotes a cable for connecting the power socket 300 to an external power source, and reference numeral 301 denotes a space through which the base 150 is inserted.

Also in this case, the contact point 303 of the second electrode part 153 is maintained. In particular, the housing 110 supporting the second electrode part 153 is formed of a material having a higher melting point than the insulating part 152.

Therefore, even when the insulating portion 152 melts, the housing 110 is not melted and its shape is maintained. Thus, the second electrode portion 153 can be supported, The contact point 303 of the contact terminal can be maintained.

Accordingly, since the lighting apparatus 100 does not fall from the power socket 300, the stability and reliability of the product can be enhanced.

That is, even if the power supplied to the power module 130 is cut off due to the disconnection of the contacts 302 of the first electrode unit 151, the base 150 of the lighting apparatus 100 may be disconnected from the power socket 300).

Meanwhile, as described above, the power module 130 may be provided with a fuse for preventing ignition of the circuit unit 132, and the fuse performs a function of cutting off current.

However, referring to FIG. 6, excessive current may be continuously supplied to the front end of the fuse to generate ignition, based on the power supply path to the power module 130 side.

In this case, when the power module 130 is ignited, the base 150 is not separated from the power socket 300 due to a difference in melting point between the housing 110 and the insulator 152, Only the contact point 302 of the first electrode unit 151 is disconnected so that the supply of external power can be cut off.

On the other hand, when the power module 130 is ignited, a gas of a high temperature is guided toward the insulator 152 to quickly disconnect the contacts of the first electrode unit 151 have.
