The shell (1) can be made in the form of various lighting fixtures/devices, including a light bulb, an embedded light (31), a ceiling light (32), a pendant light (34), and a light tube (33). An LED light bulb is taken as a primary embodiment according to the present invention, which comprises a power input terminal (15) that is rotatably connected by a rotatable joint (141) to the lower shell member (12) for the purposes of adjustment of a range of detection or an angle of image taking, the rotatable joint (141) also having a function for supporting components arranged inside the lower shell member (12); and a multifunctional module (2), which is made up of a module base (21) that has an accommodating space (25) combined with a substrate (22) that has threaded holes (28) formed in opposite sides thereof to be coupled by screwing means to threaded hole formed around the accommodating space (25) and corresponding thereto so as to close a top opening of the accommodating space (25) to protect internal components.

The internal components of the present invention are a camera lens (23) and a sensor (24). The camera lens (23) has an outer circumference over which a rubber-made sleeve is fit and the camera lens (23) is received through an opening defined in the substrate (22) to have the camera lens (23) fixed in the accommodating space (25). The sensor (24) is arranged at one side of the camera lens (23) and is also located in the accommodating space (25). The arrangement of the substrate (22) protects these components from damages caused by being exposed to the outside environment. The camera lens (23) and the sensor (24) are electrically connected, at a lower end of the accommodating space (25), to a circuit board to control operations of the components inside the accommodating space (25). The shape of the accommodating space (25) can be altered to correspond to different types of arrangement and configuration of component and is not limited to what disclosed herein. The circuit board can be a regular printed circuit board (PCB), a metal-based printed circuit board, a flexible printed circuit board, a ceramic printed circuit board, and the likes. The circuit board may comprise, mounted thereon, a system-on-chip (SOC) to allow for multiple uses of the multifunctional module (2) corresponding to various components, or alternatively, to provide an arrangement for a single function. For example, in the present invention, detection and image taking are taken as an example for illustrating multiple or single use. If an arrangement is made on the basis of SOC, then a single multifunctional module (2) can be used to correspond to various functions. Or, for the purposes of cost reduction, the multifunctional module (2) can be limited to individual functions so as to provide a multifunctional module (2) for each individual function. Thus, the present invention is not limited to such an arrangement that the multifunctional module (2) can be connected for a single way or multiple ways; and the electrical connection associated therewith can be done with various forms, such as through pins in combination with socket holes or wire bonding, being not subject to any unnecessary limitations so that a user may make substitute of the sensor (24) or the camera lens (23) according to a desired function to achieve each and simple replacement thereof.

The module base (21) has a circumference in which a plurality of notches is formed so that through rotation of a proper angle to adjust the corresponding positions, the module base (21) and the lower shell member (12) can be fit to each other. The module base (21) further comprises therein a plurality of braces extending to the circumference. The plurality of braces comprises a plurality of mounting holes (211) formed therein. The plurality of mounting holes (211) corresponds to mounting holes (121) formed in the lower shell member (12) with an LED-included lamp panel (27) interposed therebetween. The lamp panel (27) has a central portion that is hollowed to correspond to the accommodating space (25) of the module base (21). The lamp panel (27) also comprises a plurality of the mounting holes (221) that is coupled to the module base (21) the mounting holes (211) and the mounting holes (121) of the lower shell member (12) by screwing fastening means. The lamp panel (27) is provided with at least one light-emitting component (26) and in the instant embodiment, the light-emitting component (26) is a light-emitting diode. The upper shell member (11) has a circumferential flange forming a recessed portion engageable with the module base (21) and an inverted L-shaped portion formed inside the ring (13) can be forcibly pressed down to securely fix the upper shell member (11) and the lower shell member (12) to each other so as to securely fix the multifunctional module (2) in position inside the shell (1).

In the drawings, the shells (1) are respectively made in the form of an embedded light (31), a ceiling light (32), a pendant light (34), a light tube (33), and a wall light (37). Each of the shells (1) comprises therein an LED-included circuit board (36), which is secured in position inside the shell (1) or at any other mounting position by means of screwing locking means in combination with a plurality of mounting holes (211) formed in a module base (21). In more details, in case of an embedded light (31), a multifunctional module (2) is mounted to the circuit board (36) inside a lower shell member (12) and the circuit board (36) is configured with a rotatable joint arrangement to allow for direction adjustment, in both a forward direction and a backward direction, of the multifunctional module (2) through rotation, thereby providing the multifunctional module (2) with a function of adjustment of range of use. Alternatively, mounting can be made to a circuit board (36) having no rotatable joint arrangement. In the case of a ceiling light (32), the multifunctional module is mounted to a circuit board (36) inside a shell (1).
