In one of the embodiments, the light director element is lens module, and the lens module includes lens base Plate, the lens substrate front are provided with multiple raised lens, and the lens substrate is the plane with the substrate-parallel, institute Stating the exiting surface of lens includes the ellipsoid of a quarter and connects the bottom surface of the ellipsoid and the substrate, the lens Exiting surface is located on the LED, and the light that the LED is sent connects through reflecting and reflecting from ellipsoid and bottom away from the electricity The outgoing of mouth direction.

In one of the embodiments, it is provided with the lens substrate back side with the LED correspondence positions and houses the LED Enter light groove.

In one of the embodiments, it is described enter the top edge of light groove flushed with the ellipsoid top edge of the lens.

In one of the embodiments, the LED center with it is described enter light groove center superposition.

In one of the embodiments, in addition to heat sink, the heat sink are located in the PCB substrate and the LED Relative one side, the PCB substrate and the lens module are all arranged on the heat sink.

In one of the embodiments, the lens substrate, which is provided with, is used to the lens substrate being fixed on the radiating Mounting hole on plate.

Above-mentioned LED corn lamp, due to that provided with optical directory elements, can surround the light directing that LED is sent with substrate Relative one end of the electrical interface of cylinder, thus it is possible to vary LED light propagation path, reduce ray waste, enable light more Ground is irradiated to one end relative with electrical interface, improves the illumination of working face, improves light utilization, reduces power consumption, and energy-conservation subtracts Row.
