DETAILED DESCRIPTION OF THE EMBODIMENTS

FIG. 2 and FIG. 3 are respectively a perspective view and a cross-sectional view of the illumination module 1 with adjustable lighting angles. The illumination module 1 comprises a light-emitting element 2, a reflective element 3, an adjustable element 4, a rotating element 5, and a substrate 6.

The substrate 6 has a rounded groove 61. The rotating element 5 has a U shape. The bottom of the rotating element 5 is a rounded plate 51. The rounded plate 51 has two support arms 52 erected therein. Moreover, the rounded plate 51 is deposed on the rounded groove 61, and the rounded plate 51 rotates corresponding to the substrate 6.

In another embodiment, the side of the rounded groove 61 and the rounded plate 51 interlock with each other. A plurality of angular scales are depicted on the top surface of the substrate 6 and connect upon the rounded groove 61 to act as a reference when the illumination direction of the illumination module 1 is being adjusted.

The reflective element 3 is cup-shaped and has a reflective layer coated on an inner surface thereof. The two support arms 52 are pivoted on the opposite outside surface of the reflective element 3 so that the adjustable angle corresponds to the rotating element 5.

The light-emitting element 2 can be an LED, a metal halide lamp, and/or a light bulb. The light-emitting element 2 is screwed or adhered to the adjustable element 4.

The adjustable element 4 is moveable relative to the reflective element 3. To enlarge the lighting range of the light-emitting element 2, the adjustable element 4 is moved up relative to the reflective element 3. To reduce the lighting range of the light-emitting element 2 the adjustable element 4 is moved down relative to the reflective element 3.

With reference to FIG. 4, which shows a perspective view of the modular illumination device 7, the modular illumination device 7 comprises a case 74, which includes a plurality of grooves 71. The grooves 71 are arranged in a matrix, which can be arranged in any shape. The illumination devices 1 are deposed on the grooves 71, respectively. In different embodiments, the case 74 can further comprise a cover 72 and a Y base 73. The cover 72 is a transparent material deposed on the case 74. The top of the Y base 73 is pivoted with the opposite surface of the case 74 and pivots corresponding to the rotating element 5.

Please refer to FIG. 5, which is a cross-sectional view of the illumination range of the modular illumination device 7. The illumination modules 1 are deposed in the case 74. The light range and the light direction of the illumination modules 1 can be adjusted, respectively, to alter the illumination range of the modular illumination device 7.

In another embodiment, the illumination modules can be formed into two or more groups of illumination modules. The illumination modules in each group act together. The groups of illumination modules can be adjusted separately. Each group of illumination modules can operate in a different manner from the other groups of illumination modules. The lighting range and direction of each of the groups of illumination modules can therefore different. Furthermore, these methods increase fabrication speed.

In conclusion, the modular illumination device 7 with adjustable lighting angles is achieved via the illumination modules 1 which have adjustable light ranges and adjustable light directions that combine and operate together to form an adjustable illumination range.

Although possible embodiments of the invention have been described above, it is to be understood that the scope of the invention is not limited to these embodiments; in the same way, all equivalent structures and modifications as implemented in this specification and as illustrated in these drawings are covered within the scope of this invention, in order to protect the rights of the inventor.
