1. Field of the Invention
The present invention relates to a lighting device used in photographing and video recording. More particularly, the present invention relates to a lighting structure having multiple engaging members, which can be assembled with a light cover having intersecting supporting rods.
2. The Prior Arts
There are several ways to assemble a lighting device with a light cover. The followings are some commonly used assembling methods:
A first type of commonly used assembling method is to assemble the light cover with the lighting device with latches. When using latches for assembling, a mounting frame is disposed on the lighting device, and the light cover is mounted onto the mounting frame with latches. The result of such assembling is very stable, however, the disassembling process thereof can be very time consuming. In addition, the latch structure has low durability, and is likely to deform or fracture after a time of usage. The assembling process is inconvenient as well.
A second type of commonly used assembling method is to assemble the light cover with the lighting device with jointing structures. When using jointing structures for assembling, a jointing structure is disposed on the lighting device and the light cover respectively. The jointing structure on the lighting device is assembled with the jointing structure on the light cover so as to assemble the lighting device and light cover together. However, due to the limitation of the structure of such lighting device, only one light source can be installed.
A third type of commonly used assembling method is to assemble the light cover with the lighting device with fasteners. At least one threaded hole is formed on the lighting device, and the light cover is accommodated with a base. A number of threaded holes are formed on the base corresponding to the number and position of threaded holes on the lighting device. When assembling, the base is inserted into the lighting device first, and the threaded holes on the two are aligned with each other. After the threaded holes are aligned, fasteners such as screws are engaged with the threaded holes so as to assemble the lighting device and light cover together. As described above, the assembling process can be quite complicated.
The three conventional assembling methods described above each have their own advantages and disadvantages. For example, the first type of conventional assembling method provides a fast assembling process, however, the latch structure used thereof has a low durability and is likely to deform or fracture after a time of usage. The lighting device using the second type of conventional assembling method can only be installed with one light source due to its structure limitation. Lastly, the process of the third type of assembling methods is more complicated, and the lighting device cannot be quickly assembled with or disassembled from the light cover.
