Lighting Panel Assembly The present invention relates to a lighting panel assembly comprising an LED flat lighting panel.
With an increasing focus on energy and cost savings, the use of Light Emitting Diodes [LEDs] is becoming a popular choice of light source. In this regard, high performance LED flat panels are now increasingly used in large or commercial or business premises. These can be provided in various dimensions, a typical set of dimensions being 600mm by 600mm by 13mm, for use in ceilings. They provide low glare and even light distribution, as well as substantial average lifetime. In particular, they can be provided as flat panels', i.e. able to be incorporated into part of a ceiling panel system or arrangement generally formed of regular squares etc. As such, they can very easily shaped and recessed into a suitable position within the panel system or arrangement.
Meanwhile, there is significant legislation requiring the provision of emergency lighting' in buildings, particularly offices, shops, public places and commercial premises. There is now an UK standard for emergency lighting under BS5266-1.
The British and European standard BS EN 1838 goes further, in defining emergency lighting into two main types; emergency escape lighting and standby lighting.
Every building has its own specific requirements in terms of lighting and therefore its own specific requirements in respect of emergency escape illumination to take over from the normal lighting provision in the event of a power failure or circuit failure. Currently, this is commonly provided separately from the normal lighting with attendant CAPEX and OPEX cost. There is an increasing need to more easily and more cost effectively provide emergency lighting that meets the required standards.
According to one aspect of the present invention) there is provided a lighting panel assembly comprising an LED flat lighting panel having a back support panel, a front illuminating panel, and side panels thereinbetween, and having a plurality of LEDs therein to provide illumination through the front illuminating panel, and further comprising an emergency lighting pod conjoined to the back support panel, and an aperture in the back support panel to allow illumination from the emergency lighting pod through the front illuminating panel in an emergency.
In this way, emergency lighting can be provided with the LED flat lighting panel, and can provide emergency lighting from the flat lighting panel in the event of an emergency.
As mentioned above) LED flat lighting panels are known in the art. The present invention is not limited by the nature, design, size or shape of the flat lighting panel.
They can be square, rectangular or otherwise shaped. A typical size' dimension for a flat lighting panel is 60 0mm by 60 0mm, in line with commonly used dimensions in ceiling square system or arrangement.
The LED flat lighting panel in the present invention also has a height or depth which is not limiting, but which is typically several millimetres so as to provide a flat panel' shape in relation to the dimensions of the back support panel and front illuminating panel.
Some of the dimensions of the back support panel, front illuminating panel and sides are related to the type, size and design of the LED to be housed therein.
Typically, LEDs can provide power ratings of 10-100 watts, such as 35W or 45W.
The arrangement and powering of the LEDs is not further described herein) and is known to the person skilled in the art The present invention frirther comprises an emergency lighting pod. The pod may have any suitable size, shape, design and dimensions. Preferably, the width of the emergency lighting pod is substantially smaller relative to the size' dimensions of the back support panel.
The emergency lighting pod maybe conjoined to the back support panel to form the lighting panel assembly using any suitable conjoining system or arrangement. This can include any form of male-female interaction. Preferably, the conjoining achieves securing of the emergency lighting pod to the back support panel.
Optionally, the emergency lighting pod is conjoined to the back support panel via the aperture in the back support panel.
Where the lighting panel assembly is in an expected non-contact location, such as in a ceiling, the conjoining of the emergency lighting pod to the back support panel may not require locking or another form of conjoining which must be robust against any every day' contact.
Preferably, the emergency lighting pod is conjoined with the back support panel using an insert and twist' arrangement or conjunction system. Optionally this is tightened and/or secured by friction only.
Optionally, the emergency lighting pod comprises at least one tongue, and the aperture in the back support panel comprises at least one complementary cutaway.
Further optionally, the emergency lighting pod comprises two or more, typically two, three or four, tongues extending from a lower part or base of the emergency lighting pod, and there are a complimentary number of cutaways around the aperture in the back support panel to accept the tongue(s), followed by a twisting motion of the emergency lighting pod relative to the back support panel to move the tongue(s) into a position on one side of the back support panel opposite to the remainder of the emergency lighting pod on the other side of the back support panel.
The emergency lighting pod may comprise one or more lights or lighting means known in the art, including LEDs, able to provide sufficient illumination to qualify as emergency lighting in relation to the above defined standards.
Preferably, the emergency lighting is provided through an aperture in the back support panel, optionally the same aperture used to conjoin the emergency lighting pod with the flat lighting panel.
Emergency lighting can be defined as maintained', i.e. on all the time, or non-maintained', i.e. only operating when the normal lighting fails. Emergency systems or individual lighting units can be designed to operate for durations of between 1 and 3 hours after a main power supply fails, and in practice, the 3-hour design is the most popular. Some emergency lighting can be available as switchable units between maintained and non-maintained modes of operation where desired or useful.
Power for emergency lighting can be maintained through a central power source or a self contained power source. Supplying power to the emergency lighting pod can be provided in a manner known in the art) is not further discussed here.
Optionally, the emergency lighting pod is provided as a separate unit, to be fitted to an LED flat lighting panel as described above. Thus, the emergency lighting pod can be separable from the back support panel.
Thus, according to another aspect of the present invention, there is provided a kit comprising an LED flat lighting panel as defined herein and an emergency lighting pod as defined herein.
Optionally, the lighting panel assembly panel defined herein is a ceiling lighting panel.
As the emergency lighting pod can be provided as a separate unit, it can also be retro-fitted to existing LED flat lighting panels, generally being the same or similar to as described herein. Optionally, the back support panel of existing LED flat
