[Embodiment] FIG. 1 is a schematic view of a lighting device 1 of the present invention. The illuminating device 丨 includes a first light source module 12, a second unified mold (4), a floor member 16 and a base 18. The branch member 16 is connected in series with the first light source module along the vertical axis 162, and the second light source module 14 and the second light source module 14 and the second light source module 12 are rotated for the support member 16. One end of the support member 16 is placed on the -plane 2G, for example, the surface of the # sub-segment to support the branch member 16' to achieve the effect of stably setting the illumination device 1, which is convenient for description in the present invention. The first light source module 12 and the second light source module 14 are spaced apart from each other. In fact, the two light source modules are closely arranged to save space by the principle that the light source module can be rotated. The first light source module 12 includes a first lamp cover 122 and a first light source (not shown) disposed on the first light cover 122. The first light source module 12 has a light projection surface 124. With the first-back (four) 2. The thief line 发出 emitted by the first illumination source is reflected by the first lamp cover 122 and projected by the first light projection surface 124. In the embodiment of the present 201207298, the first lampshade 122 is also used as the casing of the first test 12, and thus the first back; the lamp cover 122; however, the invention is not limited thereto. In practice, the first cover: the same as the first light source module 12, the first cut 14 includes a second light cover 142 and a second light disposed in the receiving space of the second light cover (4) Source (not shown in the figure),

^ Have a second ray projection please with - the second back. The leading line of the second illumination source U is reflected by the second lamp cover 142 and projected by the second light projection surface 144. Similarly, the second lamp cover 142 is also used as the casing of the second light source module 14. Therefore, the second back surface H22 is located at the second lamp, and the second light source module 12 and the second light source module 14 are connected in series. The first back surface 1222 faces the second light projection surface (4). The light projected by the 光源g light source module 12 and the second light source module 14 and the first projection area 126 and the second projection area 146 projected onto the plane 20 are all indicated by dashed lines; and the projection path is tapered in the figure. In order to simplify the actual light projection, the light source used in the present invention is preferably a flat light, preferably a light-emitting material such as an LED or an EL.凊 Refer to Figure 2, which is the lighting device! A schematic diagram of another illumination aspect. In this embodiment, the first light source module 12 and the second light source module 14 are connected to the support member 16 via a ball joint 22, 24, respectively. The first light source module 12 and the second light source module 14 are rotated by the ball joints 22 and 24, respectively, for changing the first light source module 12 and the second light source module 14 to project light to the first projection area 126 of the plane 20. And a second projection area 146. The illumination pattern shown in FIG. 2 is based on the rotation of the first light source module 12 and the second light source module 14 with respect to the direction perpendicular to the vertical axis 162, 128, 148. The direction 128, 148 is parallel to the first light source module. 2 and the axis of symmetry of the second light source module 14.

Further, the rotation position can be used as the illumination control at the same time. For example, when the first-light source mode (4) ^the first position Π and the second position P2 are horizontally rotated, the illumination adjustment unit makes the first light source according to the position. The illumination intensity of the module 12 changes accordingly. Moreover, when the first light source module 12 is continuously rotated from the second position P2 to a third position p, the P2 is between the first position pi and the second position of the first position P3 as the first light source module. 12-bit, the first light source module 12 does not project light. In other words, the = whole order can be used: the first light source module 12 is set within the range of the angle of rotation: -^,,, and the user controls the first photo group 12 by pressing or touching the switch.

The projected light portion of the region 'second light projection surface 144 is partially shielded. Therefore, the projected light of the first ray casting surface 124 is correspondingly projected on the first projection area 126, and the projection light of the second ray projection surface 144 corresponds to the second projection area 146 and the first back surface 1222 (the 重叠 重叠 overlap area and the second At the same time, the first projection area 丨26 and the second projection area 146 formed on the plane 2〇 overlap, and the illuminance of the overlapping area will increase. The portion of the first back surface 1222 that is illuminated by the projected light of the second light projecting surface 144 will reflect the projected light to form a luminescent phenomenon. If the structure of the first back surface 1222 includes a metal plating layer, the light emitted by the second light source module 14 can be enhanced; if the structure of the first back surface 1222 includes a concave and convex surface shape, the second light source module can be softened.丨4 emits reflected light. In other words, the present invention can control the reflection of light by setting the surface morphology of the first back surface 1222, for example, to increase the effect of the upward illumination or to create a warm atmosphere with the soft reflection light. It is to be noted that in the fifth and sixth figures, the horizontal rotation of the first light source module 12 and the second light source module 14 is taken as an example.
