Wiring:
Sampling board wiring instructions:
• I*+ is the * current inflow port, and I*- is the * current outflow port. The same circuit with the same negative and positive path number, such as: I1+ is the first current inflow port, I1- is the first current outflow port
· Corresponding relationship between the number of busbars corresponding to the CN1 socket of the control board is: the I1 to I8 ports are corresponding to the current input of the 1st to 8th paths displayed on the control board.
· Corresponding relations between the number of busbars corresponding to the CN2 socket on the control board are as follows: I1 to I8 ports correspond to the 9th to 16th current inputs displayed on the control board in order.
The upper and lower bus sampling boards can be used in any combination. The upper board is small, the lower board is large, and two small boards can be used at the same time or only a small one.
Our Smart Light has a longer lifespan and more complete functions. The life of the smart light is determined by the light decay, and there are four main reasons that affect the luminous decay. 1. The raw materials of the product. The less the impurities, the less the heat dissipation. All our products are made of original brass, and the quality of the products is strictly controlled from the raw materials. Second, the heat dissipation structure of the product. We have more than ten years of work experience in structure research and development personnel. Each product has undergone heat dissipation design, heat dissipation simulation, and heat dissipation experiment to ensure the best heat conduction and heat dissipation of the product. Third, the design of the power supply, the higher the efficiency of the power supply, the better the heat dissipation. Our electronic engineers with more than 15 years of work experience adopt imported chip solutions and use the smallest space to make the power supply with the highest efficiency and the lowest temperature rise. Fourth, for LEDs, we purchase light sources from American CREE or Japan's Citizen to minimize light decay.
Smart lights is available in wattage dimming, romotely controll, module replaceable. More importantly, we are professional in OEM and ODM. We are a brass landscape lights factory integrating R&D, design and manufacturing. Please click on the product to learn more about our products.
