According to a second aspect, the present disclosure is related to a LED based lighting device assembly.
According to a third aspect, the present disclosure is related to a method for operating a dimming unit.
LED based lighting devices have been developed for a variety of lighting applications. Owing to their long lifetime and high energy efficiency, LED lamps are nowadays more popular compared to conventional lighting techniques. A dimming unit is arranged to dim the output of a LED based lighting device.
WO 2020/190128 discloses a dimming unit arranged for dimming a LED based lighting device and arranged for being provided in a standard flush- mounted wall installation box of a building wiring system. Although this dimming unit is arranged for dimming a LED based lighting device such that it is perceived as pleasant for a user, there is a need for a more intelligent dimmer.
It is therefore an objective of the present disclosure to provide a dimming unit arranged for dimming a LED based lighting allowing improved intelligence.
In a first aspect, there is provided a dimming unit arranged for dimming a Light Emitting Diode, LED, based lighting device, wherein said dimming unit comprises:
- a switch arranged for receiving an Alternating Current, AC, mains signal and for providing a supply signal to said LED based lighting device based on a switch control signal; - a controller arranged for providing said switch control signal and arranged for translating a dimming level to said switch control signal, - a dimmer arranged for providing said dimming level to said controller based on an input dimming range; - a measuring unit arranged for measuring an electric parameter of said AC means signal and/or data related to an environmental condition related to an environment of said dimming unit; wherein said controller is further arranged for providing an output signal comprising said electric parameter of said AC means signal and/or said data related to said environmental condition related to an environment of said dimming unit measured by said measuring unit.
Typically, the dimming unit is mounted in a wall installation box of a home wiring system while the LED based lighting device is mounted on the ceiling of a room. The dimming unit may then activate, and dim, the LED based lighting device. The switch is arranged for receiving an Alternating Current, AC, mains signal and for providing a supply signal to the LED based lighting device based on a switch control signal. Such a switch may, for example, be a Metal Oxide Semiconductor, MOS, Field Effect Transistor, FET, MOSFET, a power transistor or anything alike. Typically, the switch control signal is a Pulse Width Modulation, PWM, signal having a particular duty cycle. The duty cycle represents, or is correlated, to the dimming signal that is set for the LED based lighting device. The controller is arranged for providing the switch control signal and may be implemented as a microcontroller, an Application Specific Integrated Controller, ASIC, an Field Programmable Gate Array, FPGA, analogue or digital electronic circuitry, or anything alike. Preferably, the dimming unit may further comprise a power supply which is arranged for receiving the AC mains signal, and for converting the AC mains signal to a low voltage Direct Current, DC, voltage. The DC voltage may be used to power the controller.
In a preferred embodiment, the controller comprises a lookup table comprising a relationship between a current range of a preconfigured LED based lighting device and a brightness range of said preconfigured LED based lighting device. The lookup table may be stored in a register, in a memory, in a cache or anything alike. The lookup table is thus arranged to provide for a translation of the current range of a preconfigured LED based lighting device and a brightness range of the preconfigured LED based lighting device. Preferably, the controller is arranged for translating said dimming level to said switch control signal such that said brightness range is linear to said input dimming range using said lookup table. This entails that a perceived linear increase in the dimming level corresponds to a perceived linear increase in the brightness of the LED based lighting device, and that a perceived linear decrease in the dimming level corresponds to a perceived linear decrease in the brightness of the LED based lighting device.
A dimmer is provided which is arranged for providing a dimming level to said controller based on an input dimming range. The dimmer is, for example, a potentiometer or anything a like. It is noted that a user may use the dimmer for providing its input with respect to the desired dimming level of the LED based lighting device. The dimmer may provide a dimming level that is translated to an input dimming range.
A measuring unit is arranged for measuring an electric parameter of the AC means signal and/or data related to an environmental condition related to an environment of the dimming unit. The AC means signal comprises the signal of the live line, L and/or the signal of the neutral line, N. The measuring unit is in communicative connection with the controller in order to transfer measured parameters and/or data to the controller. The controller is further arranged for providing an output signal comprising the electric parameter of the AC means signal and/or the data related to the environmental condition related to an environment of the dimming unit measured by the measuring unit. Preferably, the controller is arranged for processing the electric parameter of the AC means signal and/or data related to an environmental condition related to an environment of the dimming unit and providing an output signal comprising the resulting processed data. The controller may be in communicative connection with a remote base station, a remote processor, an additional controller, or anything alike. The controller may furthermore be in communicative connection with a ventilation system, a heating system, or anything alike, in order to control the respective system.
An advantage of the dimming unit according to the present disclosure is that a dimming unit known from the prior can be replaced by the dimming unit according to the present disclosure while preserving dimming of the LED based lighting device such that it is perceived as pleasant for a user with improved intelligence.
