The utility models relates to the field of lighting technology. The general lighting LED lamp includes the base, the transition isolating element connected therewith which is made of dielectric plastic with the cavity inside, wherein the power supply for lamp operation in electrical networks is located, which is connected with LED modules made on the printed circuit board with the heat-conducting metal base and attached on the radiator. The radiator is made as rod-shaped section profile having side faces pointed at different directions, whereon said LED modules are placed, as well as ribs extending therefrom. The radiator is placed within the diffuser made of plastic which is close to glass in terms of optical performance. The radiator is made with longitudinally oriented ribs located at least on a portion of radiator height and extending from the surface of the radiator between faces for formation of heat removal surfaces. The diffuser represents the cap made as longitudinally oriented segmented shells, each of which is located in front of LED modules of one face and covers them, thereby isolating these LED modules from the ones on the adjacent face, whereas longitudinally oriented ribs are located between segmented shells. |
