Title: GARDEN LED LIGHTING APPARATUS
Abstract:
A garden LED lighting apparatus able to hold a two-pronged support frame (70), comprising power sources (20), a heat dissipation device (30), an LED light source plate (50), a lamp cover (60), and the two-pronged support frame (70); the heat dissipation device (30) comprises a heat dissipation device middle part (32) having a cambered surface shape, and heat dissipation device recessed parts (31) arranged opposite one another on the two sides of the heat dissipation device middle part (32); a plurality of second heat dissipation fins (34) are arranged on the heat dissipation device middle part (32); a heat dissipation channel (35) for air convection is formed between adjacent second heat dissipation fins (34), the two ends thereof communicating with the exterior; a heat dissipation opening (37) of the two ends of the heat dissipation channel (35) faces toward the ground; the power sources (20) are arranged inside the heat dissipation device recessed parts (31); the LED light source plate (50) is fixed below the heat dissipation device (30); the lamp cover (60) covers the heat dissipation device (30); the heat dissipation device (30) is covered by the lamp cover (60) and the downward orientation of the heat dissipation openings (37) ensures that the heat dissipation channel (35) does not easily accumulate dust.
