Why can't you just use generic models?
The track line lamp itself is designed to be simple, ultra–thin, and highly integrated—leaving very limited space for the driving power supply。If a transformer’s size, structure, or core design does not match, it can easily affect the overall system’s thickness, temperature rise, efficiency, and subsequent mass–production costs .

Concerns and requirements
space
The orbiting line lamp drives a compact internal space, and the transformer height and plate area are all controlled.
efficiency
The drive power supply must not only be lit, but also take into account the conversion efficiency and temperature increase performance.
cost
The scheme must be suitable for mass production and must not cause costs to get out of control because of special structures.
Structure
The transformer needs to truly match the light fixture power structure, rather than simply applying a general-purpose model.
