All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention. The embodiments described below and the features of the embodiments can be combined with each other without conflict.

Existing light fixtures are typically hung on a roof or wall of a room and may also be mounted on equipment. Taking the example of the lamp hanging on a wall, one end of the lamp is fixed on the wall, and the other end irradiates the room. The illumination scope of the side of the existing lamp departing from the wall cannot be changed after the lamp is fixed.

In view of this, the cover body is arranged on the outer side of the lamp, the cover body can shield part of light emitted by the lamp, and the cover body can shield light in different directions by rotating the cover body, so that the lamp which is not shielded by the cover body emits light indoors, and further the illumination range emitted by the lamp is changed.

It can be understood that the cover 42 is disposed outside the light emitting member 41 and has a light-transmitting portion, so that a part of the light emitted from the light emitting member 41 is transmitted through the light-transmitting portion, and another part of the light is blocked by the cover 42. The driving assembly can drive the cover body 42 to rotate, so that the light transmission part of the cover body 42 rotates, the direction of the light transmitted out of the light transmission part is changed, and the requirement of a user on the direction of the light is favorably met.

It should be noted that, in the lamp provided by the present disclosure, the base 1 is an installation position of the lamp, that is, the base 1 is connected to a wall, a device, and the like, so that the lamp can be installed.

Example two

It should be noted that the light emitting member 41 can be used for illumination and sterilization. When light-emitting member 41 is used for sterilization purposes, light-emitting member 41 is light-emitting member 41, and light-emitting member 41 may illustratively comprise an ultraviolet germicidal lamp, which is actually a low pressure mercury lamp. Low pressure mercury lamps are activated with relatively low pressure mercury vapor (<10-2Pa) to emit ultraviolet light, and have two main emission lines: one is 254.7nm wavelength; the other is 185nm wavelength, both of which are ultraviolet light invisible to the naked eye.

It should be noted that excessive uv irradiation may cause damage to the skin, eyes, immune system, etc. of the human body. Therefore, when ultraviolet rays are used for sterilization, the light emitted from the light emitting member 41 is often isolated from the human body.

In view of this, the cover 42 described above is made of a material capable of blocking ultraviolet rays. The detector 7 is arranged on the base 1, and can shield light when a human body is in an illumination range, so that the light is prevented from directly illuminating the human body.

Fig. 9 is a system diagram of an ultraviolet sterilization apparatus according to an exemplary embodiment, where the ultraviolet sterilization apparatus includes: a base; the ultraviolet sterilization module is arranged on the base 1, is used for emitting ultraviolet light and has an illumination range; the detector 7 is arranged on the base 1 and used for detecting whether the human body is in the illumination range; and the controller 8 is used for responding to the detection result of the detector 7 so as to control the opening and closing state of the ultraviolet sterilization module.

The structure of the ultraviolet sterilization module can refer to the structure of the lamp. That is, as shown in fig. 1 to 8, the ultraviolet sterilization module includes: a light emitting member 41 disposed on the base 1 and having an illumination side and a backlight side; a cover 42 covering the outer side of the light emitting element 41 and rotating relative to the base 1 and the light emitting element 41, the cover 42 having a light-transmitting portion; when the cover body 42 is opened, the light-transmitting part rotates to the illumination side; when the cover 42 is closed, the light-transmitting portion rotates to the backlight side; and the driving assembly is arranged on the base 1 and is used for driving the cover body 42 to rotate. Wherein the light emitting member 41 is capable of emitting ultraviolet light.

It should be noted that the illumination range includes a range of light emitted from the light-transmitting portion, and the illumination range changes with the rotation of the cover 42; alternatively, the illumination range is constant. In addition, when the ultraviolet sterilization module is turned on, the light emitting element 41 and the cover 42 are both turned on; when the ultraviolet sterilizing module is turned off, at least one of the light emitting member 41 and the cover 42 is in a turned-off state. Namely, the ultraviolet sterilization module is turned off, and the ultraviolet light emitting member 41 is in a turned-off state; or the cover 42 is closed; or the ultraviolet light emitting element 41 and the cover 42 are both in a closed state; three states are possible.

Optionally, the detector 7 includes a sensor for acquiring a position of the human body to output a position signal, and an illumination range of the ultraviolet sterilization module to output an illumination signal, and compares the position signal and the illumination signal with each other, and outputs a human body detection signal. The detector 7 may include, but is not limited to, a microwave sensor, an infrared sensor.

The microwave sensor is used for absorbing or reflecting the microwave emitted by the transmitting antenna when encountering an object to be detected, so that the power is changed. If the receiving antenna is used to receive the microwave passing through or reflected from the object to be measured, and convert it into electric signal, and then the electric signal is processed by the measuring circuit, the microwave detection is realized.

Optionally, the controller 8 is configured to receive the human body detection signal and output a control signal to control the light emitting element 41 and/or the cover 42 to be turned on or off.

It is understood that the result of the human body detection, i.e., the human body detection signal, is output to the controller 8 by acquiring the position and the illumination range of the human body in real time and comparing whether the position where the human body is located falls within the illumination range. The position for acquiring the human body can be always acquired, or can be started at the same time of acquiring the sterilization starting command.

For example, when the human body is in the illumination range, the control signal may control the light emitting member 41 to keep the on state and control the cover 42 to rotate by a certain angle to change the illumination range, so that the human body is out of the changed illumination range.

It can be understood that the illumination range of the light emitting member 41 is changed with the position of the human body, so that the sterilization process is not interrupted, and frequent activation and deactivation of the light emitting member 41 and/or the cover 42 are avoided.

For another example, when the human body is in the illumination range, the control signal controls the light emitting member 41 and/or the cover 42 to be turned off. Understandably, the processing content of the control signal is less, the energy consumption is less, and the safety performance is high.

Optionally, the ultraviolet sterilization device further includes a timer, and the timer is configured to determine whether the accumulated starting time of the ultraviolet sterilization module reaches a preset time, so as to determine the starting state of the ultraviolet sterilization module.

The ultraviolet sterilization device is provided with a preset sterilization time. For example, when the illumination range of the selective lighting member 41 is changed according to the position of the human body, the timer starts to count the time when the ultraviolet sterilization module is turned on, stops counting the time after a preset time period elapses, and outputs a timing signal to the controller 8. The controller 8 receives the timing signal and turns off the ultraviolet sterilization module.

For another example, when the illumination range is a fixed value, the timer starts to count time when the ultraviolet sterilization module is turned on. When the detector 7 detects that the person is in the illumination range, the ultraviolet sterilization module is closed, and the timer is suspended for timing. When the human body leaves the illumination range, the timer restarts timing, and the timing is stopped and a timing signal is output to the controller 8 until the time of the timer reaches a preset time length. The controller 8 receives the timing signal and turns off the ultraviolet sterilization module.

Fig. 10 is a flowchart of a control method of an ultraviolet sterilization apparatus according to an exemplary embodiment, and as shown in fig. 10, the control method of the ultraviolet sterilization apparatus includes:

s101, acquiring a starting command of an ultraviolet sterilization module;

s102, acquiring a human body detection signal;

s103, determining a control signal according to the ultraviolet sterilization module starting command and the human body detection signal;

and S104, controlling whether to turn on or turn off the ultraviolet sterilization module according to the control signal.
