DETAILED DESCRIPTION In view of the problems described above, an object of the present invention is to provide a lighting apparatus that includes a simple and small moving mechanism capable of changing the light emanation direction and that has superior heat dissipation properties.
Another object of the present invention is to provide a small-sized lighting apparatus capable of emitting light with high power and that has superior heat dissipation properties.
In order to achieve the above object, a lighting apparatus according to a first aspect of the invention includes a light-emitting unit, and a heat dissipation unit for dissipating heat generated by the light-emitting unit during light emission, wherein a heat transfer unit is connected between the light-emitting unit and the heat dissipation unit, and the light-emitting unit is in surface contact with the heat transfer unit and is connected with the heat transfer unit to be rotatable with one point or one line in the center.
In the thus-constructed lighting apparatus according to the first aspect of the invention, only the light-emitting unit can be rotated with one point or one line in the center independently of the heat dissipation unit (for example, in a state where the heat dissipation unit is immobilized).
As such, the light emanation direction can be changed by using a simple and small moving mechanism.
In addition, since the light-emitting unit is provided in surface contact with the heat dissipation unit, the lighting apparatus can be constructed to exhibit high heat dissipation properties.
A lighting apparatus according to a second aspect of the invention includes a light-emitting unit, and a heat dissipation unit for dissipating heat generated by the light-emitting unit during light emission, wherein a heat transfer unit is connected between the light-emitting unit and the heat dissipation unit, and the heat dissipation unit is in surface contact with the heat transfer unit and is connected with the heat transfer unit to be rotatable with one point or one line in the center
