SELF-CONTAINED ILLUMINATOR OF ROADS, STREETS AND YARD SIDES Russian patent published in 2010 - IPC F21S9/02 

FIELD: electrical engineering.

SUBSTANCE: proposed device comprises solar batteries (SB), storage battery (SBs), motion sensor (MS), illumination pickup (IP), control device (CD) and illumination lamp. Proposed device additionally incorporates a timer and second illumination lamp. Note here that input/output of SBs (1) is connected with input/output of CD (4). Output of MS (2) is connected with first input of CD (4). Output of SB (3) is connected with second input of CD (4). Output of IP (5) is connected with third input of CD (4). Output of timer (6) is connected with fourth of CD (4). First input of CD (4) is connected with first input of lamp (7). Second output of CD (4) is connected with second input of first lamp (7) and first input of second lamp (8) with its second input connected with third output of CD (4).

EFFECT: longer operation due to optimum use of accumulated solar energy.
