<p>The utility model pertains to outdoor and indoor lighting devices. The photodiode light source contains a reducing power converter (A), a rectifying diode bridge (7), a capacitor filter (C) and at least one photodiode (11). The reducing power converter (A) is made of a chain of sequentially connected capacitors (5) and through the rectifying diode bridge is connected to at least one photodiode (11). The capacitor filter (C) is turned on in parallel between the rectifying diode bridge (7) and at least one photodiode (11). According to the utility model, the rectifying diode bridge (7) is connected to the break in the chain of sequentially connected capacitors (5) of the reducing power converter (A). Said formulation of a photodiode light source allows same to resist abrupt fluctuations of power in the supply network and to increase the reliability of the function thereof during the process of multiple repeat connections and disconnections.</p> |
