Embodiment
In order further to understand feature of the present utility model and technology contents, see also following about detailed description of the present utility model and accompanying drawing, yet accompanying drawing only provide with reference to and the explanation usefulness, be not to be used for the utility model is limited.
See also Fig. 2 and remove the lens device circuit diagram automatically for the bathroom of the utility model first embodiment, it comprises: a power conversion unit 30; One control unit 32 is electrically connected at this power conversion unit 30; One bathroom Fog-removing mirror 36; And a trigger element 34, be electrically connected at this control unit 32 and this bathroom Fog-removing mirror 36.
Wherein this power conversion unit can be a connect diode and an electric capacity of a resistance and forms, and this resistance is 2.2K Ω, and this electric capacity is 100 μ F.This control unit is that a resistance, a photo resistance and a transistor are formed, and wherein this resistance becomes parallel connection with this photo resistance, and becomes to be composed in series with this transistor again after this resistance and this photo resistance parallel connection.This resistance is 82K Ω, and this transistor is a NPN transistor, and trigger element is a relay (Relay).
When its utilization principle is subjected to the light irradiate light for this photo resistance, because of reducing, its resistance make this photo resistance be similar to short circuit, alternating voltage is converted to the direct voltage of 12V by this power conversion unit, the electric current that is produced divided by this resistance 82K directly enters this transistorized base terminal, forms base current (I
