Title: GARDEN LED LIGHTING APPARATUS
Abstract:
A garden LED lighting apparatus, comprising power sources (20) for converting an external power supply into a voltage for powering the lighting apparatus, a heat dissipation device (30) for dissipating the heat of the lighting apparatus, an LED light source plate (50) for emitting light, and a lamp cover (60); the heat dissipation fins (36) extend upwardly from the bottom surface of a heat dissipation body (31) and radiate out toward the periphery along the inner wall of the heat dissipation body (31); a heat dissipation channel (35) for air convection is formed between adjacent second heat dissipation fins (36), the two ends thereof communicating with the exterior; a lower heat dissipation opening (37) of each heat dissipation channel (35) surrounds the periphery of the bottom surface of the heat dissipation body (31), and is parallel to the bottom surface of the heat dissipation body (30); an upper heat dissipation opening (38) of the heat dissipation channel (35) is arranged below the edge of the lamp cover (60), and is not parallel to or orthogonal to the central horizontal plane of the lamp cover (60); the heat dissipation device (30) is covered by a top cover and the arrangement of the upper and lower heat dissipation openings (37, 38) ensures that the heat dissipation channel (35) does not easily accumulate dust.
