3results about How to "Improve light receiving efficiency" patented technology

The utility model provides a vertical LED light supplement lamp which comprises a base, a supporting assembly and a connecting piece, the supporting assembly comprises a vertical telescopic rod, a transverse supporting rod, a swing rod, a swing piece and the connecting piece, a mounting part is arranged on the transverse supporting rod, the swing rod is hinged to the mounting part and can swing up and down relative to the mounting part, the swing piece is hinged to the other end of the swing rod, and the connecting piece is connected with the vertical telescopic rod. The swinging piece can swing up and down relative to the swinging rod, the connecting piece is hinged to the swinging piece so that the swinging piece can swing left and right, the light supplementing assembly comprises a light supplementing lamp panel and a light control box, and the light supplementing lamp panel is hinged to the connecting piece so that the light supplementing lamp panel can swing up and down relative to the connecting piece. The height, the position and the angle of the light supplementing assembly can be adjusted at will through the supporting assembly, and therefore people of different heights can use the light supplementing assembly conveniently, and the light supplementing assembly can adapt to various postures of people. Meanwhile, the vertical illuminance of the light supplementing assembly can be adjusted at will, so that the utilization efficiency of light generated by the light supplementing assembly is kept highest.
