兩個最受歡迎的調光器是前沿調光器(leading edge dimmer)和後緣調光器(trailing edge dimmer)。 前沿調光器(leading edge dimmer)之間的差異，電壓增加後零交叉，這個調光器抑制一段時間。 同時，後緣調光器(trailing edge dimmer)種類仍然會調節產量一段時間，但這僅僅是半週期的前景，這是負面的。導致光輸出減少，因此由LED燈泡產生的“暗淡”光。除了改變戶外區域的場景或外牆照明，調光器也可以成為節能的最好方法，從而減省建築照明設計項目，辦公照明項目，工業照明項目，室內設計照明項目，醫院項目，展覽項目等等方面的電費開支。
現今通常使用前沿調光器(leading edge dimmer)並取代傳統的電子低壓變壓器和恆流性驅動器，因些成本低廉，並且可以與各色各樣的LED照月產品一起使用。大部分因為它們提供了前沿調光器並可基本簡單調光控作。
另一方面，後端調光器(trailing edge dimmer)通過尾隨調光，可以減少“嗡嗡”，更平穩的操作和多功能調光案，可以提升LED照明的使用壽命。當您開始選擇光調光器時，因應每個項目的需求而作出選擇，首先建議與專業照明專家進行場地考察，為您的照明項目提供最佳建議。為確保有照明知識、產品保修服務及技術支持。
“Leading Edge Dimmer” or “Trailing Edge Dimmer” for your project
Light dimmers are a very technical lighting tool to have in the architectural lighting design, commercial lighting design and LED stage light collections, lighting to create a specific mood and to enjoy coloring or brightness at various times of the different occasions.
In this case, if you are considering about which type of lighting dimmer to choose, it is best way to contact a lighting consultant or specialist who will be best informed to advise you not only on the technical aspects of the device you are choosing, but also on the right dimmer to create professional in lighting solution or dimming system. Two of the most popular dimmers on the market are the leading Edge and trailing Edge light dimmers. The difference between leading edge dimmer, after voltage increases post zero crossing, this dimmer inhibits for a while. Meanwhile, trailing edge dimmer variety will yet regulate output for a while, but that's only in regard to the half-cycle's going edge, which is negative.
Resulting in a decrease in light output, hence the 'dimmed' light that is produced by the LED bulb. As well as changing the scene or façade lighting in, outdoor area, a dimmer can also be a great way to reduce energy consumption and therefore keep costs down in the architectural lighting design, office lighting, industrial lighting, interior design lighting, hospital, exhibition, education, advertising in lighting project. However, leading edge dimmer is commonly used today as well as electronic low voltage transformers and constant current LED drivers, low cost and it can be used with a variety of LED light bulbs. Trailing Edge dimmers widely mostly because they offer some significant features that the Leading Edge dimmer does not have. With a Trailing Edge dimmer it is possible to reduce 'buzzing', smoother operating and multi-way dimming which can increase the lifespan of your bulbs. When you start to choose a light dimmer, the lighting dimmer requirements are unique, it is the best way to check with professional lighting specialist first to provide the best proposal for your requirements.
