CZ29752U1 - Light source ballast with integrated wireless communication unit - Google Patents

Abstract

The ballast of the light source fitted with the integrated RF communication unit, which communicates with the control system equipped with compatible wireless interface for the control of the light fixture ballast and therefore, also the light source, is equipped with the RF communication unit with a unique ID code. The integrated RF communication unit contains an RF receiver to receive signals from the control system and an RF transceiver which communicates with the control system in both directions. The integrated RF communication unit contains an RF transceiver for two-directional communication with the control system and it is used to ensure communication between the ballasts and/or for re-translation of signals. This proposed solution reduces the number of separate components of the light fixture.

Description

Field of technology

The technical solution concerns the design of the ballast of the light source.

Prior art

A ballast is an electrical device that is connected between a power supply and one or more light sources. Its main function is the conversion (adjustment) of the supply, usually mains, current to the required parameters corresponding to the needs of the used own light source, or its interruption for switching off. Depending on the method of installation, we distinguish between separate built-in and integrated ballasts. Separate ballasts can be installed outside the luminaire, while built-in or integrated ballasts are designed for installation in the luminaire. If necessary, the control must be communicated with the ballast so that its use is as efficient as possible in terms of interrupting or limiting the power supply to an individual light source, luminaire or interconnected luminaires. This is currently realized mainly by remote control, where the RF communication unit of the luminaire (consisting of an RF receiver or RF transceiver and a control circuit for ballast control) is a separate part (component) of the luminaire assembly. The current typical assembly of the luminaire is therefore: communication unit with RF wireless interface - ballast - light source of the luminaire. The disadvantage of this solution is the fact that the RF communication unit is an element that is not integrated with other parts of the assembly.

The essence of the technical solution

The above-mentioned shortcomings are largely solved by structural arrangements according to this technical solution, where the ballast of the light source comprises an integrated RF communication unit for communication with a control system provided with a compatible wireless interface for controlling the ballast of the luminaire and thus the light source. code. The integrated RF communication unit contains an RF receiver for receiving signals from the control system and an RF transceiver for two-way communication with the control system. The integrated RF communication unit comprises an RF transceiver for two-way communication with the control system and for mutual communication between the ballasts and / or for signal retransmission.

The proposed solution reduces the number of separate components of the luminaire.

- This reduces the production costs for the assembly of the RF communication unit + own ballast by integration into a single unit

- Reduces installation costs for the production of final luminaires by simplifying the internal wiring (reducing the number of internal connections in the luminaire)

- The power consumption of the RF communication unit assembly with its own ballast can also be reduced by using their common power supply

- Last but not least, this arrangement also increases operational reliability.

Example of implementing a technical solution

The ballast of the light source comprises an integrated RF communication unit for communication with a control system provided with a compatible wireless interface for controlling the ballast of the luminaire, and thus the light source, where the RF communication unit is provided with a unique ID code. The integrated RF communication unit contains an RF receiver for receiving signals from the control system and an RF transceiver for two-way communication with the control system. The integrated RF communication unit comprises an RF transceiver for two-way communication with the control system and for mutual communication between the ballasts and / or for signal retransmission.
