In order to make the reviewer better understand the features, structure and function of the creation, the following embodiments, drawings and figure descriptions are as follows; as shown in Figures 2-6, the present LED lamp includes a base 30. a illuminating module 40, a concentrating hood 50 and a reflector 60, wherein: the pedestal 30 is a heat sink structure having a heat dissipating fin 31 protruding therefrom, and is not limited thereto, as shown in the figure. The heat sink is a two-step cylinder, and the upper stage is sleeved to fix the fixing device 32 of the lighting device.

The light-emitting component 40 is fixed to the top end of the susceptor 30 and includes at least two electrode legs 43 electrically connected to the LED illuminator 41, a circuit board 42 and the pedestal 30.

One end of the 51 is provided with a stepped hole 54 of the circuit board 42 and is sleeved with the base 10 by the fixing portion 52. The upper part of the base 10 is sleeved with the base 10 and fixed by the screw 55 to fix the fixing member 32.

The reflector 60 is an inverted triangular cone, and the surface of the cone is provided with a concave arc-shaped reflecting curved surface 61. The reflector 60 is disposed at a predetermined position above the light collecting cover 50 to form a light-emitting point of the light-emitting device, thereby visualizing different lighting devices. The height adjustment of the reflector 60 is required to be adjusted.

As shown in FIG. 2, the concentrating cover 50 and the reflector 60 may be integrally formed.
