A water decomposition device may include a hydrogen-generating electrode including a first external electrode and at least one first internal electrode formed integrally with the first external electrode, and an oxygen-generating electrode including a second external electrode and at least one second internal electrode formed integrally with the second external electrode. The first external electrode and the second external electrode are disposed to face each other, and the first internal electrode and the second internal electrode are disposed alternately in a direction perpendicular to the longitudinal direction thereof. Therefore, the water decomposition device may secure both transparency and durability even when an opaque material is used therefor.

A head lamp for a vehicle is provided, which includes a reflector for reflecting light emitted from a light source, a reflection plate for collecting the light reflected from the reflector in an upward direction, a micro-reflection module provided over the reflector to tilt and reflect the light collected by the reflection plate at a desired angle, and an optical lens for irradiating the light reflected from the micro-reflector onto a road surface. The head lamp can implement various beam patterns in accordance with road and surrounding circumferences, and irradiate vehicle information onto a road surface, thereby reducing the dazzle of other drivers of opposite vehicles and improving the field of vision of the driver to improve the safety and convenience.
