Patent attributes
An LED lamp includes: a lamp shell; a passive heat dissipating element having a heat sink connected to the lamp shell; a power source disposed in the lamp shell; and a light emitting surface connected to the heat sink of the passive heat dissipating element and comprising LED chips electrically connected to the power source. The power source comprises a power board and a plurality of electronic components mounted thereon. The power board is divided into a first mounting zone and a second mounting zone by an axis, total weight of the electronic components on the second mounting zone is greater than total weight of the electronic components on the first mounting zone, and a heat dissipating element is provided on the first mounting zone to balance the two zones of the power board in weight.
