Embodiment Construction

[0020] For ease of description, a reference number designating an element in a drawing will denote the same element in any other drawing. For purposes of clarity, specific terms are used to describe embodiments, but the invention is not to be limited to the specific terms so chosen, and it is to be understood that each specific term includes all equivalents thereof.

[0021] figure 1 This is an example of an electrical connection of a luminaire 10 according to a first non-limiting example of the invention, which may be adapted to be connected to both a normal operating power supply circuit and an emergency power supply circuit. Thus, the luminaire 10 is suitable for use in environments requiring redundant emergency power circuits, such as public buildings or public transportation vehicles such as buses, rail trains and / or monorail vehicles.

[0022] As will be described in detail throughout this specification, a luminaire 10 according to the present invention is operable to b...

Abstract

A light fixture comprising a light emitting device, a first electrical path suitable for connecting the light emitting device to a first power circuit, a second electrical path suitable for connecting the light emitting device to a second power circuit and a connector element for acquiring a selected one of a first configuration and a second configuration. Wherein in the first configuration, the light emitting device is in electrical communication with the first electrical path for being powered by the first power circuit and in the second configuration, the light emitting device is in electrical communication with the second electrical path for being powered by the second power circuit.

Description

technical field [0001] The present invention generally relates to the field of lamps, especially a plurality of lamps that can be connected in series, which can transmit the current of two different power sources through a given lamp to other multiple lamps connected to the given lamp. Background technique [0002] For safety and security reasons, lighting systems used in many public places, such as public buildings and public transport vehicles, often require both normal operational lighting (lighting provided during normal operating conditions) and emergency operating lighting (lighting provided during emergency situations) and optional ready-to-use lighting). In order to be able to provide illumination under these operating conditions, it is necessary to have different luminaires connected to different power circuits; ie a normal operating luminaire connected to the normal operating power circuit and an emergency luminaire connected to the emergency power circuit. The em...
