新型LED智慧感應燈的節能研究

IMPLEMENTATION AND RESEARCH ON NEW TYPE OF INTELLIGENT LED SENSOR LAMP

一般大樓走廊、樓梯間或廁所之感應燈在有人經過時，會由全暗瞬間變為全亮，為此眼睛會感到非常不舒適，且在感應燈全暗之狀態下，整條走廊、樓梯間呈現漆黑狀態，會讓夜歸之婦孺沒有安全感；若將照明燈改為無感應功能時，則面對了浪費能源的嚴重問題。為了解決此兩難的情況，我們開發一種「具弱光模式之新型LED感應燈」，將原本感應燈「全暗模式」改為「弱光模式」，如此一來，當有人靠近感應燈時，眼睛不會因一瞬間的光亮感到不舒適，且在無人經過時感應燈呈現弱光狀態，夜歸之婦孺不用再面對漆黑的走廊，一舉達到安全、美觀與節能之目的。本新型感應燈弱光模式之燈管耗電量只有強光模式的1/10，但其亮度約可達強光模式的一半，非常適合大樓停車場、走廊、樓梯間或廁所之感應照明，既可不須換燈座直接替換原本燈管，又可維持基本亮度。以一般15W T8 LED燈管（非感應燈）為例，若將其替換為本新型感應燈，且所裝設的地方是鮮少人經過的，則其省電率將高達90%，若是假設每小時有12人次經過，其省電率也還有81%。

In general, the sensor lamps in the corridors, stairwells or toilets of buildings will change from completely dark to full brightness when someone passes by. This will make the human eyes feel very uncomfortable, and when the sensor lamp is completely dark, the whole corridor and stairwell will be dark, making women and children feel insecure at night. If the lighting is changed to be sensor-less, there is a serious problem of wasted energy. To solve this dilemma, we developed a new type of ''LED sensor lamp with low light mode'' that changes the original ''full dark mode'' to ''low light mode.'' As a result, when someone approaches the sensor lamp, their eyes will not be uncomfortable with the momentary illumination. Furthermore, when no one passes by, the sensor lamp will stay in low-light mode, so that people returning home at night no longer have to go through dark corridors, thereby achieving safety, aesthetic and energy-saving purposes. This new sensor lamp's power consumption in low light mode is only 1/10 of the high light mode, but its brightness can be up to half of the high light mode, making it very suitable for parking lots, corridors, stairways or toilets of buildings. It only requires the replacement of the lamp but not the original lamp socket, and the basic brightness can still be maintained. Take the general 15W T8 LED lamp (sensor-less) as an example, if it is replaced by this new type of sensor lamp, and the place where it is installed is rarely passed by people, the power saving rate will be as high as 90%. Assuming that there are 12 passers-by per hour, the saving rate is still 81%.
