VERTICAL POWER SUPPLY FOR LAMP

Changzhou Jutai Electroni...

1. A vertical power supply for a lamp, comprising a shell formed in an integrated mode and a tail cover, wherein one end of
the shell is closed and the other end is provided with an opening; the tail cover is fixedly connected with the opening end
of the shell; and a hole is formed in the tail cover; the vertical driving power supply for the lamp is characterized by further
comprising a circuit board with a control circuit, a switch for generating a pulse signal, and a sealing piece; wherein at
least one part of the circuit board is mounted in a cavity of the shell; one end of the switch is welded and fixed on the
circuit board, and the other end of the switch is a free end; the sealing piece is mounted in the hole of the tail cover to
seal the hole; and after the tail cover and the shell are fixed, the sealing piece abuts against the free end of the switch
and one end of the sealing piece is exposed in the air.
