This human detection sensor lamp needs to be equipped with a human body sensor, so it has a short life span and there is no function to distinguish between daytime and nighttime, so it does not blink unnecessarily during daytime, or it can not operate CCTV in connection with CCTV in case of danger or intrusion. .

In addition, in the conventional sensor lighting structure, the lamp driving and controlling apparatuses are relatively large in external size in comparison with the lamp standard, and therefore, miniaturization is urgently required, and product dissatisfaction is frequent due to frequent troubles.

As shown in FIG. 1, a sensor 20 for detecting the presence of a forward object through a through hole formed in an outer surface of a front portion of a body portion, and a sensor driving and control circuit 30 (Not shown).

However, the driving and control circuits of the conventional LED sensor lamp are not chip-based, and the size of the sensor is small, the sensing efficiency of the sensor is as low as 75% or less, the trouble is frequent, and the life is short .
