ABSTRACT:
The present invention provides a fan to generate airflow passing around a lamp reflector. A wake region is formed near a leeward surface of the lamp reflector, and a light cut is installed in the wake region. The light cut has a fixing end and is fixed on a side end surface of a lamp holder of the lamp by means of fastening bolts, the other end keeps a selected distance away from the lamp reflector and has a suitable distance along contours of the lamp reflector toward a rear end of the lamp reflector so as to prevent the light with high illumination going through the lamp reflector to the exhausting outlet for avoiding light leakage; hence, the exhausting outlet shall not be added inclined louvers and the windage is lowered down comparatively.
