DETAILED DESCRIPTION
[0019] Drawings will be used below to disclose a plurality of embodiments of the present disclosure. For the sake of clear illustration, many practical details will be explained together in the description below. However, it is appreciated that the practical details should not be used to limit the claimed scope. In other words, in some embodiments of the present disclosure, the practical details are not essential. Moreover, for the sake of drawing simplification, some customary structures and elements in the drawings will be schematically shown in a simplified way. Wherever possible, the same reference numbers are used in the drawings and the description to refer to the same or like parts.
[0020] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and the present disclosure, and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.
[0021] Please refer to Figs. 1-3. Fig. 1 is a schematic view of a modular box light according to the first embodiment of the present disclosure. Fig. 2 is a partially exploded view of the modular box light of Fig. 1. Fig. 3 is a sectional view of the modular box light of Fig. 1. As shown in Figs. 1-3, a modular box light includes a fixture 1 and a lighting module. The lighting module is disposed on the fixture 1. The lighting module includes a frame 2 and a lighting body. The frame 2 has a plurality of barbs 21. The lighting body is disposed inside the frame 2. The fixture 1 has a mounting position corresponding to the frame 2. The fixture 1 has a plurality of snap holes 22 for allowing the barbs 21 to engage into. When being assembled with the fixture 1, the lighting module is mounted from a bottom of the fixture 1 and the barbs 21 are aligned with and engaged into the snap holes 22, so as to complete an assembly of the fixture 1 and the lighting module. Therefore, the modular box light provides an easy installation and removal of the lighting module. Consequently, the replacement of the lighting module is made convenient and the use of the modular box light is made flexible.
[0022] In practical applications, the fixture 1 has at least one installation spring 9 at its edge, for mounting to a ceiling. In this embodiment, the quantity of the installation spring 9 is two, and the installation springs 9 are disposed oppositely.
[0023] Furthermore, the fixture 1 has a plurality of flanges 23 respectively disposed at first edges of the snap holes 22, and the barbs 21 clip the flanges 23 to be prevented from sliding away from the snap holes 22. To be more specific, the barbs 21 pass through the snap holes 22 and simply clip the flanges 23, allowing a quick installation and removal of the lighting module relative to the fixture 1 without the use of any extra tools. Thus, the replacement of the lighting module is made convenient and the use of the modular box light is made flexible. Structurally speaking, the top of each of the barbs 21 is of a curved shape. This helps to reduce the resistance probably encountered when the barbs 21 pass through the snap holes 22.
[0024] In addition, the fixture 1 has a plurality of elastic plates 24 respectively disposed at second edges of the snap holes 22 opposite to the first edges. In this embodiment, each of the elastic plates 24 is fixed by a screw (not shown). An end of each of the elastic plates 24 is of a curved structure. When the barbs 21 clip the flanges 23, the ends of the elastic plates 24 abut against ends of the barbs 21 away from their corresponding flange 23, so as to prevent the barbs 21 from sliding away from the snap holes 22. In this way, the structural reliability of the modular box light is increased. The curved structure at the end of each of the elastic plates 24 can reduce friction, thus reducing the resistance probably encountered when the barbs 21 pass through the snap holes 22. Moreover, each of the second edges of the snap holes 22 opposite to the first edges is of a bevel structure 221, so as to be identified for mounting the barbs 21.
[0025] Please refer to Figs. 4-5. Fig. 4 is a partially exploded view of the lighting module of Fig. 1. Fig. 5 is an exploded view of the lighting body of Fig. 1. As shown in Figs. 1-5, in this embodiment, the lighting body is a rotary light body 91. The rotary light body 91 includes a rotary ring 31, a heat sink 32, a light emitting diode (LED) light source component and a pair of pins. The light emitting diode (LED) light source component is disposed inside the heat sink 32. The pins 311 are disposed at opposite sides of the rotary ring 31. The pins 311 penetrate into the heat sink 32 for allowing the heat sink 32 to adjust about the pins 311 by rotation. In this embodiment, the heat sink 32 can rotate at +/-30 degrees about the pins 311. However, the angle of rotation does not intend to limit the present disclosure.
[0026] As shown in Fig. 4, the frame 2 has a plurality of annular flanges 25 fitting a rotation of the rotary ring 31, such that the rotary light body 91 rotates in parallel along the annular flanges 25.
[0027] On the other hand, the lighting module includes at least one compression plate 26 disposed on the frame 2. The compression plate 26 corresponds to the rotary ring 31. In this embodiment, the quantity of the compression plate 26 is two and each of the compression plates 26 is fixed by screws. The compression plate 26 has at least one bump 261 abutting against the rotary ring 31, so as to prevent the rotary ring 31 from detaching from the frame 2. In this embodiment, the quantity of the bump 261 on each of the compression plate 26 is two.
[0028] As shown in Fig. 4, the frame 2 has a limiting bump 251 disposed on one of the annular flanges 25, and the rotary ring 31 has a limiting block 312 disposed on its outer surface. The limiting block 312 corresponds to the limiting bump 251, so as to limit an angle of rotation of the rotary light body 91 relative to the annular flanges 25. In this embodiment, the angle of rotation of the rotary light body 91 relative to the annular flanges 25 is limited to 355 degrees, so as to avoid the lighting body from spinning in 360 degrees. However, this limitation of angle of rotation does not intend to limit the present disclosure.
[0029] As shown in Fig. 5, the light emitting diode (LED) light source component includes a LED chip set 41, a reflective cup 42 and a lens 43. The LED chip set 41 is installed inside the heat sink 32 through a mounting seat (not shown). The reflective cup 42 is compressed and fixed inside the heat sink 32 through a locking ring 44. The lens 43 is also compressed and fixed inside the heat sink 32 through the locking ring 44.
[0030] In practical applications, the quantity of the lighting modules of a modular box light can be two sets or more than two sets, and different types of lighting body can be adopted. In some embodiments, the lighting body can be the rotary light body 91 or an auxiliary light body. Thus, the flexibility of usage is effectively increased.
[0031] Please refer to Fig. 6. Fig. 6 is a schematic view of a modular box light according to the second embodiment of the present disclosure. In this embodiment, as shown in Fig. 6, two rotary light bodies 91 are adopted.
[0032] Please refer to Fig. 7. Fig. 7 is a schematic view of a modular box light according to the third embodiment of the present disclosure. In this embodiment, as shown in Fig. 7, the quantity of the lighting modules is three. The lighting modules are arranged such that two auxiliary light bodies are located at the opposite sides of one rotary light body 91. In this embodiment, the auxiliary light body is an adjustable light body 92. The adjustable light body 92 is also known as truck type light body.
[0033] Please refer to Fig. 8. Fig. 8 is a schematic view of a modular box light according to the fourth embodiment of the present disclosure. As shown in Fig. 8, the difference between the fourth embodiment and the third embodiment is that the auxiliary light body in the fourth embodiment is an adjustable light body 93 instead. The adjustable light body 93 is also known as stretching projection light body.
[0034] In summary, when compared with the prior art, the embodiments of the present disclosure mentioned above have at least the following advantages:
(1) When being assembled with the fixture, the lighting module is mounted from the bottom of the fixture and the barbs are aligned with and engaged into the snap holes, so as to complete the assembly of the fixture and the lighting module. Therefore, the modular box light provides an easy installation and removal of the lighting module. Consequently, the replacement of the lighting module is made convenient and the use of the modular box light is made flexible.
(2) When the barbs clip the flanges, the ends of the elastic plates abut against ends of the barbs away from their corresponding flange, so as to prevent the barbs from sliding away from the snap holes. In this way, the structural reliability of the modular box light is increased.
(3) Since the quantity of the lighting modules of a modular box light can be two sets or more than two sets, and different types of lighting body can be adopted. Thus, the flexibility of usage is effectively increased.
