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.

Claims

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, wherein

said 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.

2. The streetlamp according to claim 1, wherein each of said motion detection system, said radio transmission and reception systems is installed inside or outside of said lamp post.

3. The streetlamp according to claim 1, wherein each of said coverage range of said motion detection system and said coverage range of said radio transmission system is omnidirectional.

4. The streetlamp according to claim 1, wherein at least one said streetlamp is positioned inside said coverage range of said radio transmission system.

5. The streetlamp according to claim 1, further comprising at least an additional illuminating unit which is turned on whenever there is insufficient lighting determined by said light sensing system.
