Market
European requirements, American requirements, Middle East requirements, etc., the requirements of different countries are different. Mainly reflected in the authentication, input parameters and so on.
Application scenario
The application scenarios and places of lamps are different, and the required waterproof, protection, anti-corrosion, and lightning protection levels are different. For special pearl occasions, special treatment is required (warehouses, gas stations, etc.).

End customer requirements
For some customers with special requirements, it is necessary to know the customer's use occasion, use conditions, as well as required functions, optoelectronic parameters, etc., which should be comprehensively considered when selecting a power supply.
Custom types:

Lamp/lighting type
Different types of lamps have great differences in structure and use occasions, so when selecting a power supply, the size, electrical parameters, safety regulations, and protection level of the power supply should also be comprehensively considered. For example, panel lights, because they are generally used in office and shopping mall environments, must consider safety requirements, installation methods, and functions (dimming and color matching) for their power supply. Since they are indoor lighting, their protection level requirements will not be too high (customers unless there are special requirements).

Power
The safety requirements of lamps and lanterns of different power sections are different. The most obvious is that the energy efficiency requirements are different. Like power factor, the requirements of different power sections are different.
Safety requirements
The safety requirements are determined by the market, the way of use and the type of lamps. Different markets have different safety requirements. At present, there are two major safety systems in the world (European system and American system); it is necessary to choose a qualified safety power supply. The safety standards of lamps and lanterns are also different. For example, the safety requirements of fire lamps and lamps for daily lighting are different; attention should also be paid to the way of use. The safety standards of mobile lamps and fixed lamps are different.

Lamp beads in series and parallel mode and parameters
First, the output voltage range of the power supply is determined according to the tube voltage drop (VF) value of the lamp beads and the number of strings, and then the output current of the power supply is determined according to the current of the lamp beads and the number of parallels. In addition, the maximum output of the power supply is selected according to the safety requirements. The no-load voltage is selected by the input power of the whole lamp and the voltage and current of the lamp board.
