LED LAMP HAVING CHARACTERISTIC OF GOOD HEAT DISSIPATION

摘要

An LED lamp having the characteristic of good heat dissipation comprises an LED lamp base (1) and a driving power source (2). The lamp base is provided with a disc-shaped heat radiator. An LED chip holding cavity is provided in the centre of the heat radiator of the lamp base. The LED chip is encapsulated in the holding cavity. The holding cavity is covered by a lens (5). The heat radiator of the lamp base comprises several bar-shaped fins extending radially outward from the centre of the disc. The driving power source is provided in the heat radiating power box separated from the lamp base. The heat radiating fins are provided around the outer surface of the power box. The power box is connected to the lamp base by two joint poles (3).
