Definitions

  • This invention relates to lights, and concerns in particular such lights, powered by electricity and usable as safety lights, night lights, or other forms of secondary lighting, as may be incorporated into an otherwise conventional electric light mounting, socket or bulb.
  • a low level secondary lighting system to illuminate an area in a building, such as a hall, a landing or some stairs, so that without switching on any main lighting system an occupant of the building can see well enough to move safely around the building after dark.
  • a low level secondary source of light is generally referred to as a "safety light” or a "night light” (a night light was originally a small, stubby candle, but these days it will, like a safety light, be a low power electric light bulb - maybe as little as 5 watts, or even less - that is sufficient to allow someone with dark-adapted eyes to see and move around in relative safety) .
  • safety light is for the most part used hereinafter, but it will be understood that it includes what might in other circumstances be called a “night light” - is much like a conventional electrical plug, save that it incorporates a small light bulb, glow bulb, LED, or the like. It plugs into an ordinary wall socket, and when the socket is switched on it glows gently, providing sufficient light to let a User - a person using this facility - see the surroundings. This type of safety light is quite satisfactory for most purposes, and yet it suffers from a number of trivial but irritating problems.
  • the light-emitting plug is operated from a wall socket, and modern wall sockets (in a house) are at or near floor level, the light it provides is all down near the floor, which not only makes it difficult for the User to see anything that is higher up but means that the light is too easily blocked by furniture and the like, so that it may fail to illuminate the more distant parts of the area.
  • the light-emitting plug is in a socket it can only be switched on and off by operating the socket's switch (if it has one), which is inconvenient when the area's main light system is probably turned on and off from a quite different switch.
  • the mere fact that the plug is in the socket means that socket cannot be used for anything else unless the plug is first removed (or an adapter is employed) . - 3 -
  • the invention provides an electric light, usable as a safety light, night light or like form of secondary illumination, that is operatively - and possibly physically - connectable to an ordinary (or primary illumination) light, and that is switchable from the very switch that operates that ordinary light but separately from that light.
  • the invention provides two electric lights, one for primary illumination, the other for secondary, each of which is connected to a common control circuit itself connectable to a switch by which may be supplied the power to the lights, the control circuit being such that it allows power to one or other light depending on the time since the switch was last used to turn a light on and then off. - 4 -
  • the invention provides an electric light - that is to say, a device which is powered by electricity and which when actuated outputs electromagnetic radiation in that part of the spectrum corresponding to that of visible light.
  • a light thus means a light device, or a source of light, and as is so in general parlance extends to include not only the actual source of the light (the filament of a light bulb, say) but also the mechanicals associated with that source - thus, the bulb, the bulb mounting, the power cabling and the physical structure supporting the mounting (as in a bedside light, a standard lamp, a wall lamp bracket, or a pendant light and its ceiling “rose”).
  • the expression “light” used hereinafter has whatever meaning is appropriate in the circumstances.
  • the light may take any appropriate form not only as regards its overall physical and mechanical structure but also as regards its mode of operation.
  • it can for example be a conventional filament bulb, a neon discharge bulb, a Light Emitting Diode (LED) device or a thin-film electroluminescent device (such as that from Limelite, of Austin, Texas, USA).
  • LED Light Emitting Diode
  • a thin-film electroluminescent device such as that from Limelite, of Austin, Texas, USA.
  • the invention is a light usable as a safety light, a night light or some other secondary- illumination device.
  • the light is a relatively low-powered light, providing sufficient light for objects within an area to be seen (but, in night light form, not so much as to become obtrusive).
  • the actual light output required of the light may depend of the size of the area to be illuminated; for a very large area, normally lit by many lights, a single "safety light” might actually have a fairly high output, in the tens or even hundreds of watts).
  • Safety lights and specifically night lights
  • this concept should be well understood; for use in a dwelling's normal bedroom, landing or hall safety light an output of around 5 watts maximum is most convenient.
  • the secondary illumination light of the invention is operatively, and most preferably physically, connectable to an ordinary light.
  • the invention's secondary light - the actual source of the light, together with the various mechanical and control systems associated with it - is connectable to, or is actually part of, the mechanicals associated with the ordinary light - thus, the bulb, the bulb mounting, the power cabling and the physical structure supporting the mounting (as in a bedside light, a standard lamp, a wall lamp bracket, or a pendant light and its ceiling "rose").
  • the invention's light is attached to, or built into, a wall or ceiling mounting
  • the second is one where the - 6 -
  • invention's light is attached to, or built into, a conventional bulb socket (in the "attached” case, rather like an intermediate socket); and the third is one where the invention's light is actually built into a "conventional” light bulb itself.
  • the secondary light of the invention is a small package consisting of an actual light generating device (a neon bulb, say) together with mounting and control means
  • this package can be designed to be either detachably attachable to or integrally formed with the ordinary light's mounting (such as a ceiling rose) or with the ordinary light's bayonet or screw socket (into which the ordinary light bulb is fitted).
  • the ordinary light's mounting such as a ceiling rose
  • the ordinary light's bayonet or screw socket into which the ordinary light bulb is fitted.
  • that package can be built into the light bulb itself - this would be ideal for the relatively new sort of mini-fluorescent bulb made by Mazda or Phillips (and the like), which already has a relatively bulky base portion (with the "starter” and other necessary components in it).
  • the package being attachable to the light socket it is conveniently constructed as an intermediate "link" sited between the ordinary socket and the ordinary light bulb, and has a male bayonet/screw fitting to allow it to be attached to the ordinary socket and a female bayonet/screw fitting to allow the ordinary light bulb to be fitted into it.
  • the secondary light of the invention is physically associated with an ordinary pre-positioned light, in operation it necessarily sheds its light exactly where it is required - and, especially in the case of such a light associated with a room's central ceiling rose light mounting, that light will emanate from a sufficiently high vantage point that it is likely to shine to the furthest extent of the relevant area without being blocked by other objects in that area.
  • a key feature of the secondary light of the invention is that it is switchable from the very switch that operates that ordinary (primary) light with which the secondary light is associated.
  • This can be arranged in any appropriate way, but one very advantageous way - a way which obviates the need for any additional wiring of any sort - depends firstly on the secondary light being positioned electrically to take its power from the same source - the same conductive leads - that power the ordinary light, and secondly on the two lights being associated with control means that can be sent switching signals along the normal power leads to cause that control means to switch power to one or other of the two lights - either to the secondary light and not to the ordinary light or not to the secondary light but instead to the ordinary light.
  • the switching control circuit determines which of the primary and secondary light sources is switched on - in a common wall-switch lighting system, the control circuit switches on - energises - the primary light if the wall switch is switched on and left on but it switches on the secondary light if the wall switch is rapidly switched on, off and then on. This may be organised by including within the control circuit two different counting devices that between them in effect measure the times taken since the power was switched off and since the power was switched on.
  • Each counter counts down once power is switched off, and then counts back up once power is switched on, but the first counts fast while the second counts more slowly; if on connection of the power supply the first counter's value exceeds the second counter ' s value then the circuit energises the secondary light, while if not then the circuit energises the primary light.
  • the invention provides a novel form of secondary light system - especially suited for use as a safety light (and so a night light, or some other type of secondary illumination) - that is in use connected to and powered from an ordinary, primary light system, and indeed that is switched from the very switch that operates that ordinary light. It naturally sheds its light exactly where it is required, and can most advantageously be switched on or off exactly as the main light itself is switched off or on.
  • the one lighting system of primary and secondary lights may include one or more primary light (such as the bulbs in a chandelier or a wall-light pair) associated with one or more secondary light (such as a glow plate of the type of our earlier aforementioned Patents, a rose- mounted light, or a bulb-incorporated light).

  • LPl main (or primary) light
  • LP2,LP3 two safety (secondary) lights
  • the main lamp LPl is connected to the mains via an electronic switch.
  • the switch is implemented by thyristor Q4, with its gate signal amplified by MOSFET transistor Q3, and bridge rectifier D3-6.
  • MOSFET transistor Q3 MOSFET transistor
  • D3-6 bridge rectifier
  • the thyristor Q4 When the thyristor Q4 is on, the voltage across the bridge rectifier will be small (i.e. insufficient to light LP2 and LP3), and the lamp LPl will be lit. When it is off, but mains voltage is still available, virtually the entire mains voltage will be across the switch. This voltage is used to power the (green) night light neons, LP2 and LP3.
  • the collector of Q2 is connected to the gate of MOSFET Q3, so that when Q2 is off, the electronic switch is turned on, and the main lamp is lit. Conversely, with Q2 on, the switch will be turned off, LPl will be off, and neons LP2 and LP3 will be lit.
  • the bistable latch is powered by a half-wave rectified power supply comprising diode Dl, resistor Rl, Zener diode ZD1 (which limits the operating voltage to 22 volts) and capacitor Cl, which provides a degree of smoothing .
  • the important ( and novel ) aspect of the circuit so far as concerns the present invention is the means by which it is ensured that the bistable latch is set with Q2 on and Ql off, when it is powered up for the first time (thereby ensuring that the main light LPl is on), - 13 -
  • capacitors C2 and C3 may be assumed to be discharged. As voltage is applied to the bistable, the capacitors start to charge up. Capacitor C3 starts to charge up via resistors R15, R4 and the base of Q2, while C2 charges up via diode D2, resistors R3, R5 and the base of Ql .
  • the time constants (Tc) are given by
  • Tc3 (C3 * R15 * R4)/(R15 + R4)
  • Tc2 (C2 * R3 * R2)/(R3 + R2)
  • C3 will therefore charge up much faster than C2.
  • the charging current will cease. There will therefore certainly be a time during which the C3 charging current through the base of Q2 has ceased, but the C2 charging current through the base of Ql is continuing. In this condition, the only stable state for the circuit is with Ql on and Q2 off. The main light will therefore be lit. Because the latch is stable in either state, this condition will then continue indefinitely, even after both the capacitor charging currents have ceased.
  • diode D2 will be reverse-biased, and the longer time constant formed by C2 and R3/R5 will be ineffective.
  • Capacitor C3 will charge up, at least partly via R4 and the base of Q2. This will turn Q2 on.
  • the reverse bias on D2 and the low voltage on the collector of Q2 ensure that there is no base drive current for Ql , and it cannot turn on. The result is that in this case, the bistable latch remains indefinitely with Ql off, Q2 on, and the night light neons LP2 and LP3 lit.
  • the timing elements are resistor-capacitor combinations
  • alternative implementations can readily be devised, where the time measurement is achieved digitally, by means of an oscillator and two counters which count up/down at different rates. Such an implementation would have the advantage of the times being much more accurately determined.
  • the important components of the system are therefore two timing elements, which count in one direction in the presence of electrical power and the opposite direction in its absence. Both timing elements should have the characteristic of a maximum and minimum value.
  • the third essential component is a bistable memory device, which retains one of two stable states when both counters are at their maximum or minimum, and selects which stable state to adopt when the values of the two counters differ, according to whether one counter or the other is the larger.

Abstract

Beaucoup d'immeubles comprennent des systèmes d'éclairage secondaire qui peuvent être utilisés pour fournir une intensité lumineuse faible mais suffisante pour une sortie de secours ou un endroit où un éclairage vif peut être inapproprié. L'invention propose un nouveau système d'éclairage secondaire, qui lorsqu'on l'utilise, peut être relié (physiquement aussi bien qu'électriquement) à un éclairage ordinaire (primaire) (101, 102) à partir duquel il est alimenté, ledit système pouvant être soit un organe de montage de lampe (un montage de type plafonnier ou une lampe de table), soit une douille d'une ampoule, soit l'ampoule elle-même. L'invention concerne, en outre, un éclairage de sécurité alimenté, relié à une lampe qui est commutée à partir de l'interrupteur même qui fait fonctionner le système d'éclairage ordinaire auquel le système de sécurité est relié, et à partir duquel il est alimenté. Ce système d'éclairage de sécurité diffuse sa lumière non seulement là où elle est nécessaire, et à partir d'un point suffisamment élevé qui est susceptible de briller le plus loin possible de la zone en question sans être bloqué par d'autres objets de ladite zone, mais il peut aussi très avantageusement être allumé ou éteint exactement lorsque le système d'éclairage principal et lui même sont allumés ou éteints.
