The luminaire device 3 of the present invention includes a base 31, a support column 32, a plurality of light emitting modules 33, a diffusion cover 34, and a control module 35. The supporting pillar 32 is disposed on the base 31, and the light emitting modules 33 are disposed on the side surfaces 321 of the supporting pillar 32 respectively, and function to generate light beams (not shown) such that the light beams can be output from the side surfaces 321 of the supporting pillar 32 respectively, that is, the light beams can be output from various angles. The diffusion cover 34 is sleeved on the base 31 and covers the plurality of light emitting modules 33 therein, wherein when the plurality of light beams are projected to the diffusion cover 34, the plurality of light beams are diffused according to a plurality of diffusion particles (not shown) contained in the diffusion cover to generate a light diffusion effect. The control module 35 is disposed in the base 31 and electrically connected to the plurality of light emitting modules 33, and can control the plurality of light emitting modules 33 according to the received external signal S1 (please refer to fig. 5), so that the lighting device 3 generates a light emitting effect corresponding to the external signal.
Referring to fig. 4 and 5, fig. 5 is a schematic diagram of an internal structural block of a lamp device according to a preferred embodiment of the invention. The control module 35 includes a main circuit board 351, a signal receiving module 352, and a control unit 353. The main circuit board 351 is disposed in the base 31 and electrically connected to the light emitting modules 33.

In the preferred embodiment, the Micro light sources 332 are Micro light emitting diodes (Micro LEDs) or sub-millimeter light emitting diodes (Mini LEDs), wherein the volume of the Micro light sources 332 using Micro light emitting diodes is smaller than that of conventional light emitting diodes, so that the plurality of Micro light sources 332 can be arranged in a more compact arrangement.
It should be noted that the supporting pillars 32 in the preferred embodiment are square pillars, so the number of the side surfaces 321 of the supporting pillars 32 is 4.

In fig. 5, the signal receiving module 352 may receive the incoming signal S1 and output a control signal S2 corresponding to the incoming signal S1 to the control unit 353. For example, the following example: the signal receiving module 352 is an audio signal receiving module, and when the signal receiving module 352 receives the external signal S1 in the form of audio, the signal receiving module 352 converts the external signal S1 in the form of audio into the control signal S2 and outputs the control signal S2 to the control unit 353. The control unit 353 may control the light emitting conditions of the plurality of micro light sources 332 according to the external signal S1 in the form of audio.

Example two: the signal receiving module is an information signal receiving module which is specially used for receiving the external signal in the form of network information, wherein the external signal in the form of network information is the weather state of network weather forecast. When the signal receiving module receives an external signal in the form of network information, the signal receiving module analyzes the external signal in the form of network information, and outputs the control signal corresponding to the external signal according to an analysis result of the signal receiving module to output the control signal to the control unit. The control unit can control the light emitting conditions of the micro light sources according to external signals in the form of network information. When the analysis result of the signal receiving module aiming at the external signal in the network information form is sunny days, the plurality of micro light sources can be controlled to generate yellow light beams; and when the signal receiving module analyzes the external signal in the form of network information to obtain a result of rain, the signal receiving module can control the plurality of micro light sources to generate blue light beams. The above two examples are only illustrative and not limiting.
