HIGH-ANGLE LIGHT-EMITTING DIODE (LED) BULB LAMP WITH NATURAL INTERNAL AND EXTERNAL AIR CONVECTION RADIATION FUNCTION

摘要

A high-angle light-emitting diode (LED) bulb lamp with a natural internal and external air convection radiation function comprises a lamp cover (1), a lamp cap (4), a radiating pillar (2) and a power cavity (3). The lower part of the power cavity (3) is fixedly connected with the lamp cap (4), and the upper part of the power cavity (3) is fixedly connected with the lamp cover (1). The radiating pillar (2) is in the shape of polygon and fixed in the middle of the power cavity (3); an LED chip (6) is bonded to every side of the radiating pillar (2) to achieve the high-angle lighting effect. The upper and lower parts of the power cavity (3) and the top part of the lamp cover (1) are provided with a plurality of holes (5, 7); and the radiating pillar (2) is provided with a plurality of radiating passages. The power cavity (3), and the holes (5, 7) on the lamp cover (1) are in communication with the radiating passages of the radiating pillar (2), and radiation is implemented through natural air circulation.
