<p>An LED lamp includes a base that has a transition insulating element connected therewith which is made of a dielectric plastic with a cavity inside. A power supply is located inside the cavity, and is connected to a plurality of LED modules. Each LED module is attached to a PCB with a heat-conducting metal base that is attached to a radiator. The radiator is made with a rod-shaped section profile having side faces pointed at different directions on which the LED modules are placed, as well as ribs extending therefrom. The radiator has longitudinally oriented ribs located on a portion of the radiator height and extending from the surface of the radiator between faces for formation of heat removal surfaces. The radiator is within a diffuser made of plastic. The diffuser has a cap made as longitudinally oriented segmented shells, each located in front of LED modules of one face to cover them, and thereby isolating LED modules from ones on the adjacent faces. The longitudinally oriented ribs are located between the segmented shells.</p> |
