A further object of the present invention is that the focus source of the soft focus composite light source can be selected or replaced as needed to achieve the most suitable and optimized soft focus source configuration.

Another object of the present invention is to reduce the cost of the light source and the cost of installation.

In order to achieve the above effects, the structural features of the present invention include: an annular base, The outer peripheral edge is formed with an external thread; a projection light source is disposed in the hollow region of the annular base; a base light source is disposed in the annular region of the annular base; a homogenous lens is disposed in front of the base light source; A positioning ring having a leading edge relative to the homogenous lens having an inner flange, the inner edge forming an internal thread with respect to the external thread, and the positioning lens is screwed to the annular base to position the homogeneous lens.

In addition, a plurality of heat dissipating bodies are formed on the back of the annular base; further, the projection light source is an MR16 cup lamp, and the basic light source is an LED light emitting module; and the homogenizing lens is a diffusing plate with adjustable light transmittance. a glass plate or an acrylic plate, and the homogenous lens is a central hollow light-transmissive annular homogenizing lens or a central solid light-transmitting annular homogenizing lens; and the basic light source is disposed in an annular region of the annular base The upper position is parallel to the homogeneous lens; or the base light source is disposed at an inner circumferential surface of the annular region of the annular base so as to be perpendicular to the homogeneous lens; A plurality of through holes are arranged in the middle of the plurality of heat dissipating bodies, and a socket is arranged to receive a socket. The plug light source has a plug portion thereon for electrically connecting with the socket; and further, the socket has elastic clips on both sides thereof. Hold on both sides of the projection source.

Thereby, the illumination design of the projection light source and the base light source is simultaneously provided on the annular base, and the illumination of the accent illumination can be provided by the projection light source and the illumination of the ambient illumination can be provided by the basic light source.

Fig. 4 is a cross-sectional view showing the structure of a second possible embodiment of the present invention.

First, referring to [FIG. 1] to [FIG. 3], the first feasible embodiment of the present invention includes: an annular base 10, the outer circumference is formed with an external thread 11, and further to the annular base 10 A plurality of heat sinks 12 are formed on the back; a projection light source 20 is disposed in the hollow region of the annular base 10. In this embodiment, the projection light source 20 can be an MR16 cup lamp, but is not limited thereto; 30, disposed in the annular region 13 of the annular base 10, and the basic light source 30 can be an LED lighting module; a homogenizing lens 40 is disposed in front of the base light source 30, and the homogenizing lens 40 is adjustable a light diffusing plate, a glass plate or an acrylic plate, and the homogeneous lens 40 may be a central hollow light-transmissive annular homogenizing lens or a central solid light-transmitting annular homogenizing lens; and a positioning ring 50 with a leading edge opposite to the The homogenizing lens 40 has an inner flange piece 51, and the inner edge is formed with an internal thread 52 with respect to the external thread 11, and the positioning lens 50 is screwed to the annular base 10 to position the homogeneous lens 40.

In this embodiment, the basic light source 30 is disposed above the annular region 13 of the annular base 10 so as to be parallel to the homogeneous lens 40, so that the base light source 30 is projected from top to bottom. Projected through the homogeneous lens 40.

FIG. 4 is a cross-sectional view showing a structure of a second possible embodiment of the present invention, and the same structure as that of the first possible embodiment is represented by the same reference numeral, and the difference is only that the basic light source 30 is disposed on the annular base 10 . The inner circumferential surface of the annular region 13 is positioned perpendicular to the homogeneous lens 40, and the base light source 30 is projected from the side surface, reflected by the annular region 13, and then projected by the homogeneous lens 40.
