▎ 摘　　要

NOVELTY - A LED street lamp comprises a lamp main body provided with an LED lamp street lamp upper cover (1) and an LED lamp street lamp lower bottom (2). The LED lamp street lamp upper cover is coated with a powder material (5). The LED lamp street lamp upper cover is provided with bumps (4). The LED lamp street lamp lower bottom is coated with a heat conducting film. The LED lamp street lamp upper cover and the LED lamp street lamp lower bottom form a sealing cavity (3). The sealing cavity is filled with heat conducting liquid (8). An LED light source (6) is fixed on the lower bottom of the LED street lamp head. USE - LED street lamp. ADVANTAGE - The heat generated by the LED street lamp is conducted to the heat conducting liquid through the heat conducting film, and the heat conducting liquid is transmitted to the surface of the upper cover of the LED street lamp by circulating convection, and the powder material coated on the surface transmits the heat to the air through the heat radiation and conduction. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the LED street lamp. Upper cover (1) LED lamp street lamp lower bottom (2) Sealing cavity (3) Bumps (4) Powder material (5) LED light source (6) Heat conducting liquid (8)
