Description
本創作係有關一種大功率燈具照明系統，特別是指僅使用單組驅動電路，即可點亮多個各自獨立的大功率燈具，同時具有調光功能之照明系統。This invention relates to a high-power lamp lighting system, specifically a lighting system that can light up multiple independent high-power lamps using only a single set of drive circuits and has a dimming function at the same time.
按，在戶內外廣場、體育場、各種商業廣場以及工業工廠、礦場等大型場所或公路，會用到大功率燈具進行照明，以使場所內能獲得足夠的光線，供人們進行娛樂或工作活動。而隨著LED照明的普及，為尋求更為節能環保及長壽命的照明方案，目前在大型場合所應該用的大功率照明燈具，已逐漸由更為符合要求的LED所取代，這類LED照明燈，通常可稱為大功率LED照明燈具。Press, in indoor and outdoor squares, stadiums, various commercial squares, industrial factories, mines and other large places or highways, high-power lamps are used for lighting, so that the place can get enough light for people to carry out entertainment or work activities. . With the popularization of LED lighting, in order to seek more energy-saving, environmentally friendly and long-life lighting solutions, the high-power lighting fixtures currently used in large-scale occasions have been gradually replaced by LEDs that more meet the requirements. This type of LED lighting Lamps can usually be called high-power LED lighting fixtures.
傳統大功率LED照明燈具內部使用高功率LED為光源，雖可達到強光效果，也伴隨了耗電及高熱的問題：且就其供電控制系統而言，其對每一照明燈具內部均需提供一專用電源供應器做為驅動電路用來驅動點亮LED；如第1圖所示係為複數照明燈具組成的照明系統，整體照明系統主要具有一控制電路11以及複數照明燈具12，複數照明燈具12分別與該控制電路11連接，而複數照明燈具12內部具有一驅動電路121以及一發光模組122，因每個照明燈具12個別配置一個驅動電路121，不但造成製造成本上的浪費，而且驅動電路所產生的熱量更導致照明燈具的發熱量高居不下，以致於溫度過高，必須仰賴另設的散熱機構加強散熱。Traditional high-power LED lighting fixtures use high-power LEDs as light sources. Although they can achieve strong light effects, they are also accompanied by problems of power consumption and high heat: and in terms of their power supply control system, each lighting fixture needs to provide internal A dedicated power supply is used as a drive circuit to drive and light the LED; as shown in Figure 1, it is a lighting system composed of multiple lighting fixtures. The overall lighting system mainly has a
除產生前述的耗能大量產熱問題外，如果要對燈具進行亮度調整，必須在每一照明燈具的驅動電路安裝調光單元，才能達到單一照明燈具調光的目的。如果要對一個以上的照明燈具同時進行調光，還必須對每一照明燈具搭配調光單元，逐一配置調光控制線路，才能達到群組調光的目的。In addition to the aforementioned energy consumption and heat generation problems, if the brightness of the lamps is to be adjusted, a dimming unit must be installed in the drive circuit of each lighting fixture to achieve the purpose of dimming a single lighting fixture. If more than one lighting fixture is to be dimmed at the same time, each lighting fixture must be equipped with a dimming unit and the dimming control circuits must be configured one by one to achieve the purpose of group dimming.
再者，該照明系統就配線而言，因複數照明燈具12分別與該控制電路11連接，所以每個照明燈具12要個別拉一條獨立的電連接線與該控制電路11耦接，不僅線材成本提高且配線作業複雜，且會有壓降問題，又受限於壓降問題習有照明系統無法安裝於較大範圍的建築場域。Furthermore, in terms of wiring in the lighting system, since the plurality of
