Description

LED lighting device

Technical field

The present invention pertains to a lighting device, and relates to a lighting device shaped like a hemispherical shape, and more particularly to a lighting device that is shaped like a hemisphere or a quarter ball using a spherical or similar spherical cooling device.

Background technique

The heat sink used in the prior art LED lighting device is usually a flat plate heat sink, and the shape is as shown in FIG. Since the heat sink fins of the flat heat sink are all the same size and shape, even if the fins are different in size, the overall shape is flat. These flat-type radiators have different heat dissipation effects in different directions when used outdoors. When the direction of air flow is consistent with the direction of the fins of the heat sink, the heat dissipation effect is good, but when the air flow direction is perpendicular to the direction of the fins of the heat sink, only the heat radiating fins that are in contact with the outside air can dissipate heat and cannot flow the air. Introduced between the middle fins; and when the direction of air flow is perpendicular to the direction of the fins of the heat sink, the wind resistance of the heat sink is large, affecting the structural stability of the heat sink and the light fixture using the heat sink, especially in outdoor applications. Too much wind resistance will make the overall structure of the luminaire unstable and even blown off. Moreover, the shape of the LED lamp constructed by the flat-shaped radiator is relatively square, the installation takes up space, the shape change is small, and the LED lamp of various curved shapes cannot be assembled.
