LED power supply design considerations
The primary consideration in power supply design is to meet the basic needs of customers. This includes three major elements: first, the choice of lamp bead, the use of mainstream lamp beads, while ensuring the quality, but also reduce the cost of the product; secondly, the product specifications, according to the product specifications to design the appropriate topology; again performance requirements, including accuracy, efficiency , lumens, PF values, etc.
It is not enough to meet basic needs, and different customers will have different requirements for quality. Generally used for engineering or exporting overseas lamps, the power supply needs to pass the corresponding certification; for the power supply design with high reliability requirements, single-chip integrated, electroless design can be adopted, and corresponding abnormal protection is provided; temperature characteristics, temperature When rising, the current is reduced, and the temperature is always kept in a safe range to protect the luminaire.
It is manufactured according to the GB4004-83.JB/T7600.3-94,DIN46395,it is made with the punched and compacted iron plate,and shaped with welding.With the big hardness and the lingt weight,it can fit for using in bunching,stranding,cabling,extrusion and the armouring machine.
