## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a modular illumination device with adjustable illumination modules, and particularly relates to a modular illumination device with a plurality of adjustable illumination modules that have an adjustable light range and an adjustable light direction. Furthermore, the adjustable light range and the adjustable light direction, when combined and operating together, form an adjustable illumination range.
2. Description of the Prior Art
Traditionally, a modular spotlight 1a has a plurality of light-emitting elements 2a which can include an LED, a metal halide lamp, and/or a light bulb. Moreover, the light-emitting element 2a has a substrate 3a that has a plurality of holes 4a, and the light-emitting elements 2a are respectively deposed inside the holes 4a. A modular spotlight 1a increases the brightness of the light via the light-emitting elements 2a. However, there are no adjustable structures to alter the angle of the light-emitting elements 2a. As such, after the light-emitting elements 2a are deposed in the holes 4 of the substrate 3a, the range or direction of the light-emitting elements 2a cannot be changed. Therefore, the illumination range of the spotlight 1a cannot be changed.
In the traditional manufacturing process for modular spotlights, a special substrate for the spotlight 1a is produced that has different angled holes 4a. This makes the light-emitting elements 2a shine in different directions and changes the illumination range. An alternative method provides light-emitting elements 2a that have different light ranges to change the illumination range of the modular spotlight. However, the cost and development time is large and is not viable under the keen competition of the modern marketplace.
Accordingly, this invention is provided to improve the abovementioned disadvantages of the modular spotlight.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide a modular illumination device that allows a user to adjust the illumination direction of the illumination modules. The modular illumination device comprises a substrate, a rotating element, a reflective element, an adjustable element, and a light-emitting element. The rotating element rotatably is disposed on the substrate, and the rotating element rotates corresponding to the substrate. The reflective element is pivoted on the rotating element, and pivots corresponding to the rotating element. The adjustable element is moveably disposed on the substrate, and moves corresponding to the reflective element. The light-emitting element is disposed on the adjustable element.
The light range of the light-emitting element is therefore enlarged by adjusting the adjustable element up relative to the reflective element. The light range of the light-emitting element is reduced by adjusting the adjustable element down relative to the reflective element. The angle of elevation of the light is changed by adjusting the reflective element. The light direction can be rotated around 360 degrees by adjusting the rotating element. Thereby, a modular illumination device is provided for all illumination directions by adjusting the above elements.
Another object of the present invention is to provide an illumination module for adjusting the illumination range, wherein the modular illumination device is comprised of the illumination modules that are arranged in matrix. The modular illumination device further comprises a case, which includes a plurality of grooves in which the illumination modules are respectively disposed therein. By adjusting the light angle and direction of the illumination modules, the desired illumination range can be achieved by a user.

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.
