RADIO-LINKED STREETLAMP
First Claim
1. A streetlamp comprising a lamp post, at least a illuminating unit, a light sensing system, a motion detection system, a radio transmission system, and a radio reception system, whereinsaid light sensing system positioned at a top location of said lamp post continuously measure a lighting condition in the vicinity of said streetlamp and activates and deactivates said motion detection system when said lighting condition is below and above a setting of said light sensing system;
- said motion detection system, once activated, detects movement and activities occurring within a coverage range of said motion detection system, turns on said illuminating units when a disturbance is sensed, and triggers said radio transmission system to transmit a radio-frequency wireless signal;
said radio transmission system transmits said radio-frequency wireless signal to a coverage range of said radio transmission system;
said radio reception system, after receiving said radio-frequency wireless signal, turns on said illuminating units;
said illuminating units positioned at a top location of said lamp post are turned on under two conditions;
(1) when there is insufficient lighting determined by said light sensing system; and
(2) when said motion detection system has sensed some disturbance or said radio reception system has received said radio-frequency wireless signal from a neighboring streetlamp.

Abstract
A streetlamp according to the present invention will be turned on under two conditions: (1) when there is insufficient lighting determined by a light sensing system; and (2) when a motion detection system has sensed some disturbance within its coverage range or when a radio reception system has received a radio-frequency signal from a neighboring streetlamp. An illuminating streetlamp will automatically turn itself off after a period of time and if any one of the two conditions is not satisfied.
