[0002] When installing a substrate containing a DOB power supply in an existing LED lamp, generally the following two methods are adopted:

[0003] (1). Installing columns on the outer surface of the heat dissipation housing, so that the power supply is in plane contact with the heat dissipation housing to achieve a good heat dissipation effect, but it will occupy a large installation space and affect the aesthetics of the lamp;
