Description
Technical Field
The present invention relates to a housing for a lighting device, in particular a floodlight, more particularly an outdoor floodlight lighting device and even more particularly a LED floodlight lighting device, and to a lighting device.
Background
It is known to use floodlights for illuminating, for example, outdoor sports stadiums, construction sites or as stage lighting for illuminating instruments or performance stages like concerts and dramas.
In this respect, floodlights comprising one LED or more likely a plurality of LEDs as light source are increasingly entering the field of application of floodlights, because they have a significantly lower power consumption compared to other conventional light sources like halogen lamps. In addition, LEDs have a longer lifetime.
Because floodlights are commonly used for outdoor applications, like illuminating outdoor sports fields, they may be exposed to dust and to moisture due to contact with rain or fog. Therefore, in order to ensure safe operation of the lighting device, a dustproof and waterproof design must be provided for the lighting device.
In this respect, it is known to provide floodlights with a housing: the LED and required driving components for driving the LED are housed in a sealed manner in the housing.
In order to provide electrical connection of the LED to the driver inside the housing, common housings comprise an outlet opening for the electrical wiring, wherein the opening is sealed with respect to the sheath of the wiring to provide a waterproof design at the outlet opening.
Therefore, in order to make electrical contact, the wiring must be connected to an external wiring that provides power. Therefore, additional water tight (waterlight) connection boxes or connectors, respectively, are required. The connection box remote from the housing provides a sealed interior space for the connection of the aforementioned wiring. To this end, the connection box comprises a wall in which a watertight access for the two wires is provided, so that both wires can be inserted into an inner space for electrical connection.
