The invention relates to a luminaire (10) comprising illuminants (170) for generating light, and a control unit (110) for controlling the illuminants (170), and at least one further element (140), in particular an operator control element (143) or a sensor (142), for generating control information that influences the operation of the luminaire (10), wherein the control unit (110) is configured in such a way that a self-test is carried out after a supply voltage has been applied to the luminaire (10). Said self-test is carried out automatically and independently in an analysis mode of the luminaire (10), wherein the control unit (110) checks the luminaire (10) for the presence and/or the functionality of the at least one further element (140). Depending on the checking result, and the type of further unit (140) checked, the control unit (110) controls the illuminants (170) such that a temporally variable light emission (171) signals the checking result. Measuring devices (200, 210, 220) are additionally specified which detect the checking result by measurement of operating parameters of the luminaire (10) and present this information preferably by way of a display (211, 221) of the measuring device (200, 210, 220). A method is likewise specified which includes checking the at least one further element (140) and controlling the illuminants (170) by means of the control unit (110).

The ambient lighting system also includes: a control unit configured to control the RGB LED light sources in order to present light animations; and a touch sensor configured to detect touch of the contact surface in a defined region, which is configured to define, along the optical system at least one soft key. The ambient lighting system further includes: a voice command recognition system electronically connected to the control unit and configured to recognize voice commands; and a projector configured to project an image, such as a symbol and/or logo, on the contact surface.

The light-emitting device includes a main body, a light-emitting module, and a press part located on the main body and configured to control on or off of the light-emitting module. The main body is provided with an accommodation space having the light-emitting module arranged therein. The main body includes a light guide, and light emitted by the light-emitting module is emitted outside of the main body through the light guide. The light guide includes a light exit surface and a light entrance surface. The light entrance surface is located on the circumferential inner sidewall of the accommodation space, and the light exit surface is located on the circumferential outer sidewall of the main body, and light emitted by the light-emitting module is emitted outside along a side of the main body.

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).

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.
