DESC:FIELD OF THE INVENTION

The present disclosure relates to lighting devices and more particularly, relates to a lighting device with a LED driver.

BACKGROUND

Generally, a lighting device is defined as a means to provide light to achieve practical use and create an aesthetic effect. The lighting device is used everywhere, for example, in homes, corporate buildings, streetlights, etc. The lighting device accounts for approximately 45% of the total power used in the house or the office premises. Hence, many technological developments have occurred to reduce power consumption by the lighting devices. For instance, conventional lamps have been replaced by LED lamps which consume less power and are now available at an affordable rate in the market. Further, in this regard, different types of LED-based lighting devices are available in the market, for example, an edge-lit panel light and a back-lit panel light. The back-lit panel light is defined as an array of LEDs placed on a plate horizontally to illuminate a lower space of the back-lit panel light, through a diffuser. Further, the edge-lit panel light is defined as a configuration where a row of LEDs is placed on a frame of a panel of the edge-lit panel light.

Further, an LED-based lighting device has an LED driver which regulates the power required for a single LED or an array of LEDs. The LED driver rectifies high voltage AC current to a lower voltage direct current required to operate the LED-based lighting devices. Conventionally, the LED driver is attached at a back side of the LED-based lighting device with a plurality of fasteners, where the LED driver is concealed with a top cover member. However, after prolonged use, the LED driver might need to be replaced. In that case, an operator has to disassemble the LED driver from the LED-based lighting device by removing the plurality of fasteners and taking out the top cover member to access the LED driver. This results in increased maintenance time for the LED-based lighting device. This also results in increasing assembly and disassembly time of the LED-based lighting device. Further, the top cover member, as required to cover the LED driver, conforms with a dimension of the LED-based lighting device which results in the requirement of additional material and ultimately increases the weight of the LED-based lighting device. Additionally, the replacement of the LED driver in the conventional configuration also results in fatigue for the operator.

Hence, it is desirable to provide an LED-based lighting device having an LED driver ensuring ease of maintenance of the LED driver while overcoming the aforementioned problem as occurred in the conventional configuration.

SUMMARY

This summary is provided to introduce a selection of concepts, in a simplified format, that are further described in the detailed description of the invention. This summary is neither intended to identify key or essential inventive concepts of the invention and nor is it intended for determining the scope of the invention.

The present disclosure aims to provide a lighting device having a LED driver ensuring the ease of maintenance of the LED driver.

In an embodiment of the present disclosure, a lighting device, that has, an LED driver, a housing unit, and a driver housing assembly, is disclosed. The LED driver is adapted to operate at least one lighting unit. The housing unit is adapted to receive the at least one lighting unit. The driver housing assembly is adapted to detachably attached to the housing unit. The driver housing assembly includes a mounting unit and a cover. The mounting unit having a base member is adapted to be detachably attached to a rear side of the housing unit. The mounting unit is adapted to receive the LED driver thereon. The cover is detachably attached to each of the housing units and the mounting unit to conceal the LED driver positioned on the base member.

The present disclosure ensures a simple configuration of the lighting device with the mounting unit to mount the LED driver.
