LED Emergency Lighting

LED’s will illuminate when the electricity is removed.

An internally mounted battery charging and supply loss detection circuit board is powered via the mains 230 vac supply. The bright white light emitting diodes for the emergency lighting is powered by the 3.7VDC Lithium Ion rechargeable battery and will only illuminate in a power cut or test switch is pressed.

LED Emergency Socket

Operates exactly like an existing socket until it detects the power is removed, then it automatically switches to battery operation and illuminates the bright light emitting diodes.
A 3.6v rechargeable battery enables the light emitting diodes to stay on independently for up to a minimum of three hours or until the electrical power returns.

The idea was brought about after seeing the 24-storey Grenfell Tower fire which broke out on 14 June 2017. When a fire occures the electrical supply normally fails and if emergency light power sockets were installed, then you would have illumination close to the floor in a smoke filled area.

LED Emergency Panel / Supply LIGHT

LED Light operates when the PCB detects the power is removed, then it automatically switches to battery operation and illuminates the bright light emitting diodes.
A 3.6v rechargeable battery enables the light emitting diodes to stay on independently for up to a minimum of three hours or until the electrical power returns.

The idea was thought off when working on a construction site on an isolated electrical distribution board with no lighting available in the location due to the distribution board isolation. Also experienced similar cases when working on isolated control panels, again no lighting to see the fuses and terminals.

Don't fear a power cut!

New LED socket lights up a room for a minimum of THREE HOURS during an energy outage, Light socket made by Maxking Ltd in Bedfordshire could let people see in blackouts.

Emergency Light Socket

Operation

 The socket operates the same as an existing socket until it detects the power is removed, then it will automatically switches to battery operation. This enables LED emergency lights to stay on independently for up to three hours until the power returns.

Benefits for  emergency lighting.

Can be installed in grade listed buildings and provides the property with constant lighting, making it safe for people within the premises to evacuate calmly in the case of a fire, even if mains power is affected.

Emergency Light closer to the floor can reduce working time or money lost in trying to sort out situations if the mains power does fail.

LED’s are more efficient than incandescent bulbs, they waste very little energy as heat, unlike most light sources.

They can light up quickly and can be turned on and off frequently.
LED’s are less fragile and have longer lifespans.

LED Emergency Socket

The battery used in this circuit is a 3.7v Li-ion battery 2600mAh.
Charging current in this circuit is 5.9mA, which is acceptable for slow charging since this circuit is for emergency lighting.
The 3.6V COB (LED strip are 3 Watts in power, so a 2600mAh battery at
3.6VDC = 9 Wh (Wh = mAh × V / 1000) 3 hours light.

Further Information

Power socket with emergency light, comprising of a power socket front switched or un-switched with a small circuit board behind the socket front, a rechargeable battery and emergency light emitting diodes embedded into the socket front.

The internally mounted circuit board being provided with a external power from the sockets power supply input terminals. The rechargeable battery and the emergency light emitting diodes being in electric connection with the circuit board respectively; when the power line is connected to the socket, the emergency lights are in an off state, not illuminated; when the power line is disconnected from the external socket, fuse tripped or power cut, the emergency lights are in an on / lighted state.

The main advantage of installing emergency lighting is that your building will never be in darkness.

If an incident does occur it is crucial to make it as easy as possible for the occupants to make their way out quickly and safely through the designated escape routes.

Emergency Socket

The power socket has the function of emergency lighting as well as providing power supply to appliances, enabling the emergency lights to be powered and light up when the socket mains power supply is unexpectedly cut off.

The emergency circuit charges the 3.7v battery using the 230V AC electric line, when the 230V AC power is removed, the Light Emitting Diodes (COB) will illuminate automatically.

Working voltage: 1A, 250V
Working temperature: -15 to 40 C
UK 3 pin socket output: 13A, 250V
Fits any standard back box (minimum depth of 35mm)

If your property is in an area that suffers from a disrupted power supply then emergency lighting is definitely something to consider.

A typical high-power LED will give you 10 years maintenance free service when used for 12 hours every day, thus saving the maintenance costs of replacing 20 new filament lamps over the 10 year life span and the environmental cost of their disposal.

 

Technical Information

Technical Information

A 820nF (0.82uF) 250 or 400 volt AC capacitor is dropping the 230 volt AC (Tested 242.4 VAC) to low volt AC (Tested 21.8 VAC).
X Rated capacitor 0.82uf 250 or 400 Volt AC – X=1/{2xPIx50x0.82x(1/1,000,000)} = 38818.278 Ohms or 38.8 Kilo ohms. 230V/38.8 = 5.92mA

Bleeder resistor 270R 0.25W is used to remove the stored current from the C2 (0.82uF) 250 VAC capacitor.

BR IN4007 D1 through D4 rectifies the low AC to DC.

The capacitor 470uF 16V or 25V makes the DC ripple free (Tested 4.1 VDC).

This S9012 PNP transistor in TO-92 package is perfect for switching applications and switches power from the 3.7 volt battery to the light emitting diodes (COB – Circuit On Board).

Zener Diode is commonly used as a voltage regulator. Being a diode normally operated in the reverse bias and at the breakdown voltage, the zener diode allows the current to keep the voltage across the diode close to the zener breakdown 4.7 volts. Therefore it protects other devices against voltage pulses.

The UK Guidance document

A minimum duration of three hours should be used for emergency lighting if premises are not expected to be evacuated immediately in the event of a supply failure, such as sleeping accommodation or places of entertainment, or if the premises are expected to be reoccupied when the supply is restored without waiting for batteries to recharge.

And a minimum duration of one hour should be used only if the premises are expected to be evacuated immediately on supply failure and not reoccupied until full capacity has been restored to the batteries.

It is imperative that as a UK company you comply with the UK Guidelines set out above.

By doing so, it means a building can be re-entered after there has been some kind of mains failure as there is still significant emergency lighting in place to meet the minimum requirements. The European standards mean that even if there is a five minute failure the building can not be re-entered as you would not meet the one hour minimum requirement.
