One embodiment of the present disclosure provides an external detection see-through door of a cabinet that stores objects. The external detection see-through door includes a transmission window, a sensor configured to detect a specific external condition in front of the transmission window, a light emitting module configured to increase an amount of emitted light according to a signal from the sensor, which has detected the specific external condition, to increase an amount of light that is reflected from inside the cabinet and heads toward the transmission window, and an optical film that is provided on the transmission window and has a light transmittance that prevents the cabinet from being see-through from the outside before the sensor detects the specific condition and allows the cabinet to be see-through from the outside due to light that is reflected from inside the cabinet and transmitted through the transmission window and the optical film due to the light emitting module increasing the amount of emitted light according to the signal from the sensor that has detected the specific external condition.

The control system for a stage light fixture with photobiological safety includes a control unit connected to a motor assembly and a light source and configured to control the stage light fixture to operate, and a distance sensor connected to the control unit, and configured to acquire an instant distance from a living being to the stage light fixture. The control unit stores a light radiation hazard exposure radiance limit value and a light fixture irradiance value acquired in advance per unit of time and distance, and acquires a parameter of the living being entering an irradiation danger zone according to the instant distance, the light radiation hazard exposure radiance limit value, and the light fixture irradiance value. When a hazard condition reaches the parameter of the living being entering the irradiation danger zone, the control unit controls the stage light fixture to move to eliminate the hazard condition.

The present invention relates to a delay switch module comprising: a delay switch (110), which is connected in parallel to a load switch (SW), is switched on during a set delay-off-time from when the load switch (SW) is switched off, and is switched off when the delay-off-time has elapsed, so that an operation stops when the delay-off-time has elapsed after the load switch (SW) is switched off; and a control unit (120) for sensing on/off switching of the load switch (SW) if there is an on/off switching operation of the load switch (SW) after the load switch (SW) is switched off, and controlling an operation-off of the delay switch (110) so that the set delay-off-time of the delay switch (110) changes according to the on/off switching operation of the load switch (SW).

A rearview mirror system for a vehicle providing a direct reflection of scenes in good light and an enhanced display of scenes in bad lighting includes a housing defining an opening, a display screen arranged at the opening, a camera, a fill light lamp, and a controller. The display screen is light-pervious at only one side. The camera and the fill light lamp are arranged on the housing. An image processing chip and the controller are arranged between the display screen and the housing. When ambient brightness is below a preset brightness value, the camera and the fill light lamp are activated, the camera captures images of side and rear scenes of the vehicle and generates an optical signal, the image processing chip, based on the optical signal, outputs an enhanced image on the display screen for better driving safety. A vehicle including the rearview mirror system is also disclosed.

Disclosed embodiments provide a lighting apparatus with microwave induction. The microwave induction lamp emits electromagnetic waves through an antenna, such as a planar antenna. When a moving object enters the electromagnetic wave environment, the waveform is reflected and folded back and received by a microwave transceiver via the antenna and serves as a trigger signal. When the antenna receives the feedback waveform, a microcontroller-operated circuit activates a lighting device (e.g., a bank of light emitting diodes (LEDs)) in response to detecting the trigger signal. Disclosed embodiments use the trigger signal to turn the lighting device (lamps) on and off and further include a delay function, via a timer, to keep the lighting device activated for a predetermined period after detecting the trigger signal. In this way, a safe and efficient automatically activated lighting apparatus is provided.

A system includes: a light source that emits pulsed light that illuminates a user's head portion; a photodetector that detects at least part of pulsed light returning from the head portion and that outputs one or more signals corresponding to an intensity of the at least part; electrical circuitry; and a memory that stores an emotion model indicating a relationship between the one or more signals and emotions. Based on a change in the one or more signals, the electrical circuitry selects an emotion by referring to the model. The one or more signals include a first signal corresponding to an intensity of first part of the reflection pulsed light and a second signal corresponding to an intensity of second part of the reflection pulsed light. The first part includes part before a falling period is started; and the second part includes at least part in the falling period.
