BRIEF DESCRIPTION OF THE DRAWINGS [0018] FIG. 1 is a schematic diagram of an embodiment of the present invention.
[0019] FIG 2 is a schematic diagram of a first draft solution of a pyroelectric infrared sensor.
[0020] FIG 3 is a schematic diagram of an embodiment of a sound sensor.
DESCRIPTION OF THE EMBODIMENTS [0021] The present invention will be further described in the detailed embodiments below with reference to accompanying drawings. The following embodiments are merely exemplary, but not all the embodiments of the technical solution of the present invention.
[0022] As shown in FIG 1, FIG 2 and FIG 3, an intelligent illumination device includes an illuminator 1 and a controller 2 for controlling the illuminator 1 to operate. The illumination device further includes a sound sensor 3 for acquiring sound information and a pyroelectric infrared sensor 4 for acquiring a human body infrared signal. The sound sensor 3 is communicated with the controller 2 after being serially connected with the pyroelectric infrared sensor 4. The controller 2 controls the illuminator 1 to operate according to parameters detected by the sound sensor 3 and the pyroelectric infrared sensor 4. The pyroelectric infrared sensor 4, the sound sensor 3 and the illuminator 1 are all communicated with the controller 2 through a wireless network. The intelligent illumination device further includes a mobile terminal 5. The ' mobile terminal 5 is communicated with the controller 2 through a network. The controller 2 is I controlled to be turned on or off by the mobile terminal 5.
[0023] The intelligent illumination device of the present invention means that the illuminator < 5 1 is automatically turned on or off according to information detected by the corresponding
I sensor, without manual operation. Intelligence means that there is no need for manually intervening too much for control purposes.
[0024] In this embodiment, the sound sensor 3 is disposed in series with the pyroelectric ! infrared sensor 4. The sound sensor 3 is configured to detect sound. The pyroelectric infrared < 0 sensor 4 is configured to detect a human body infrared feature. In practical applications, only < after the pyroelectric infrared sensor 4 detects the human body infrared feature and the sound
I sensor 3 is triggered by emitted sound, the controller 2 controls the illuminator 1 to be illuminated. In this way, the controller 2 may be effectively prevented from malfunctioning, that is, external noise triggers the sound sensor 3 to enable the illuminator 1 to be accidentally illuminated. Accordingly, the performance of the intelligent illumination device is optimized and the energy is saved.
[0025] The sound sensor 3, the pyroelectric infrared sensor 4 and the controller 2 are all of a conventional structure in the prior art and can be conveniently commercially available. The illuminator 1 may be an energy-saving lamp or an LED lamp.
[0026] The mobile terminal 5 in this embodiment is mainly configured to turn off the controller 2 when a user leaves for a long time, that is, after the controller 2 is turned off, the sound sensor 3 and the pyroelectric infrared sensor 4 do not sense corresponding signals any more, and are in a sleep state. Therefore, the controller 2 may be effectively prevented from malfunctioning.
[0027] The controller 2 should have a certain logic control capability. For example, the illuminator 1 should be automatically turned off after being turned on for a period of time. The solution is suitable for places such as stairways or corridors. The corresponding illuminator 1 may be turned off according to a signal detected by the pyroelectric infrared sensor 4. A manner of turning the illuminator 1 off is not limited in detail, and may be reasonably set by those 30 skilled in the art as needed.
[0028] As shown in FIG. 2, in some possible embodiments, the pyroelectric infrared sensor 4 includes a housing on which a suction cup 41 for fixing the pyroelectric infrared sensor 4 is disposed, and the suction cup 41 is bonded to the housing. A marking body for marking the pyroelectric infrared sensor 4 is disposed on the housing. The marking body is positioned on one side of the housing opposite to the suction cup 41.
< [0029] The marking body is a label. The label is bonded to the housing. A transparent | protective layer 42 is further disposed on the housing. The transparent protective layer 42 is j bonded to the housing. The label is positioned between the transparent protective layer 42 and < 5 the housing.
I [0030] The marking body may be replaced with other structures with a marking capability.
The marking body mainly plays a marking role to facilitate the mounting of the pyroelectric j infrared sensor 4.
) ' [0031] As shown in FIG. 3, in some possible embodiments, the sound sensor 3 includes a * 0 fixing base 31 on which an accommodating slot for accommodating the sound sensor 3 is * disposed. The sound sensor 3 is inserted into the accommodating slot. Meanwhile, an elastic ' layer 32 for improving the fixing strength of the sound sensor 3 is bonded to the side wall of the accommodating slot. The elastic layer 32 has a thickness of not less than 5mm. The elastic layer 32 may be made of a rubber layer or a sponge layer. After the sound sensor 3 is mounted in the accommodating slot, the elastic layer 32 elastically deforms to effectively position the sound sensor 3.
[0032] The elastic layer 32 should not be too thin, so as to prevent the elastic layer 32 from effectively playing a positioning role.
[0033] In some possible embodiments, the mobile terminal 5 is a smart phone, or the mobile 0 terminal 5 is a tablet computer.
It is appreciated that the aforesaid embodiments are only exemplary embodiments adopted to describe the principles of the present invention, and the present invention is not merely limited thereto. Various variants and modifications can be made by those of ordinary skill in the art without departing from the spirit and essence of the present invention, and these variants and 25 modifications are also covered within the scope of the present invention. Accordingly, although the invention has been described with reference to specific examples, it is appreciated by those of ordinary skill in the art that the invention can be embodied in many other forms. It is also appreciated by those of ordinary skill the art that the features of the various examples described can be combined in other combinations.
