Detailed Description
In the following description, numerous implementation details are set forth in order to provide a thorough understanding of various embodiments of the present disclosure. It should be understood, however, that these implementation details are not to be interpreted as limiting the disclosure. That is, in some embodiments of the disclosure, such implementation details are not necessary. In addition, for the sake of simplicity, some conventional structures and elements are shown in the drawings in a simple schematic manner.
Fig. 1 is a perspective view illustrating a germicidal lamp 100 with a detection function according to an embodiment of the present disclosure. Fig. 2 is a front view of the germicidal lamp 100 with a detection function of fig. 1. Referring to fig. 1 and fig. 2, the germicidal lamp 100 with a detection function includes a housing 110, a circuit board 120, an ultraviolet light source 130, a detection module 140, a controller 150, and an indicator 160. The housing 110 has an opening 111. The circuit board 120 and the controller 150 are located in the housing 110. The circuit board 120 is provided with at least one ultraviolet light source 130, a detection module 140 and an indicator light 160. The controller 150 is electrically connected to the circuit board 120. The ultraviolet light source 130, the detection module 140 and the indicator light 160 are disposed in the opening 111.
When in use, the germicidal lamp 100 with the detection function can sense whether the user is in front of the ultraviolet light source 130 or detect the distance between the user and the user through the detection module 140, so that the controller 150 can control the on/off of the ultraviolet light source 130 according to the signal of the detection module 140. Thus, the germicidal lamp 100 with detection function can prevent the ultraviolet light source 130 from being turned on when there is a user in front of the ultraviolet light source or when the ultraviolet light source is too close to the user, so as to prevent the eyes or the skin of the user from being damaged.
In the present embodiment, the opening 111 of the housing 110 may be rectangular, but is not limited thereto. The opening 111 is used for emitting light from the ultraviolet light source 130 to the surface of the object to be sterilized, and for the detection module 140 to sense the light, and for the user to view the on/off and color of the indicator light 160. In addition, the germicidal lamp 100 with detection function may further include a light-transmissive cover 115. The light-transmitting cover plate 115 covers the opening 111 of the housing 110, so that moisture or dust can be prevented from entering, and the service life can be prolonged.
In this embodiment, the number of the ultraviolet light sources 130 may be 6, and the number of the indicator lamps 160 may be two. The two indicator lights 160 may be a safety indicator light 161 (e.g., green) and a hazard indicator light 162 (e.g., red), respectively. The detection module 140 may be located between the safety light 161 and the hazard light 162. The controller 150 may turn on the safety light 161 or the hazard light 162 according to the signal of the detection module 140. For example, when the safety light 161 is turned on, it is directed to the object to be sterilized, and the ultraviolet light source 130 is turned on; when the hazard indicator 162 is illuminated, indicating that there is a user in front of or too close to the user, the uv light source 130 is turned off.
In addition, the ultraviolet light source 130, the indicator light 160 and the detection module 140 may be linearly arranged on the circuit board 120. In this embodiment, the uv light source 130 and the indicator 160 are disposed on the circuit board 120 with the detection module 140 as a center of symmetry. The arrangement of the uv light sources 130, the indication lamps 160 and the detection modules 140 and the number of the uv light sources 130 and the indication lamps 160 are not limited to the present disclosure, and are determined by the requirement of the designer. In the present embodiment, the controller 150 is not provided on the circuit board 120 but is shielded by the case 110. In other embodiments, the controller 150 may be disposed on the circuit board 120 and exposed from the opening 111 of the housing 110.
In the present embodiment, the ultraviolet light source 130 may be a deep Ultraviolet (UVC) Light Emitting Diode (LED). The wavelength of deep Ultraviolet (UVC) is between 100nm-280nm, and has the functions of sterilization and disinfection. The ultraviolet rays can irradiate the microorganisms such as bacteria, viruses and the like to cause cell death or lose reproductive capacity, thereby achieving the effects of sterilization and disinfection. The deep ultraviolet light emitting diode as the ultraviolet light source 130 has the characteristics of safety, environmental protection, high efficiency, low energy consumption, long service life, no chemical residue and the like.
The detecting module 140 may be a distance Sensor (Proximity Sensor), an Ambient Light Sensor (Ambient Light Sensor), a Time of Flight (Time of Flight) device, a Structured Light (Structured Light) device, or an Active Stereo Vision device. Distance sensors typically function by emitting an electromagnetic field or beam of electromagnetic radiation and observing changes in the electric field or return signal. The ambient light sensor is mainly applied to the light sensor for detecting the change of an ambient light source, has high sensitivity to ambient light, and does not act when no ambient light exists (such as being arranged in a bag pulled up by a zipper), and otherwise does not act when the ambient light irradiates (such as being arranged in a bag opened by the zipper). A cross-sectional view of the time-of-flight ranging device is shown in fig. 6. The distance measuring device can emit laser and receive scattered light by the detector to calculate the two-way flight time of photons, thereby obtaining the distance between the detector and the object. The structured light device can project a specific light spot to the surface of an object and is collected by the camera to obtain the position and the surface relief of the object. The lens image capturing device captures digital images by a camera and judges the vision of an object through calculation.
Fig. 3 is a schematic diagram of the germicidal lamp 100 with a detection function shown in fig. 2 in an on state. When the germicidal lamp 100 with detection function detects that there is no user U or other person in front (i.e. human face determination), or detects that the user U or other person is located at a safe distance (i.e. distance detection), the controller 150 lights up the safety indicator lamp 161, and then the ultraviolet light source 130 can be turned on (automatically or manually) for sterilization.
Fig. 4 is a schematic diagram illustrating the germicidal lamp 100 with detection function of fig. 2 in an off state. When the germicidal lamp 100 with the detection function detects that there is a user U or other person in front (i.e. human face determination), or detects that there is a dangerous distance between the user U or other person (i.e. distance detection), the detection module 140 transmits a signal to the controller 150, the controller 150 lights up the dangerous indicator lamp 162, and at this time, the ultraviolet light source 130 is forcibly turned off and cannot be turned on.
It should be understood that the connection and function of the elements described above will not be repeated, and will be described in detail. In the following description, other forms of germicidal lamps with detection function will be described.

The difference from the embodiment of fig. 2 is that the housing 110 of the germicidal lamp with detection function 100b includes a lamp portion 112, a handle portion 113 and a rotating shaft 114. The lamp portion 112 and the handle portion 113 are pivotally connected to each other via the shaft 114, and by this design, the germicidal lamp 100b with detection function can be folded to reduce the size for carrying (as shown in fig. 8). In addition, in the present embodiment, the fingerprint identifier 180 is disposed on the grip portion 113 of the housing 110, and when the user holds the grip portion 113, the fingerprint identifier 180 can identify the user through the biometric function, so as to avoid the improper use (especially, the user with insufficient cognitive ability). In this embodiment, the ultraviolet light source 130, the detection module 140, the indicator light 160 and the transparent cover plate 115 may be disposed in the lamp portion 112 of the housing 110. The controller 150 and the fingerprint identifier 180 may be disposed in the grip portion 113 of the housing 110, but are not limited to the disclosure.
