Description

Energy-saving emergency lamp

Technical field

The utility model relates to field of light fittings, relates in particular to a kind of bulb.

Background technology

Traditional is bulb such as incandescent lamp, the electricity-saving lamp etc. of the energy with the electricity, makes mostly at present and is with externally threaded metal-back lamp holder (being screw thread mouth formula lamp holder), to cooperate tapped lamp socket.Installing only needs the lamp holder screw-in or screws out lamp socket to get final product when changing, do not need professional knowledge generally can operate per capita, thereby use very easy; Same lamp socket can be according to one such as required optional incandescent lamp or electricity-saving lamps, thus can exchange between the conventional bulb, highly versatile.No matter be indoor dwelling house or office building, auditoriums, hotels or outdoor road or sub-district (park), the bulb on this quasi-tradition meaning still is the first-selection of illumination now.The indoor place in the parlor of dwelling house, hotel, dining room or the like particularly, illumination and attractive in appearance laying equal stress on, it is more more outstanding than outdoor to decorate composition, light fixture (lampshade) structure is often comparatively complicated, need to reach the effect of change multiterminal, thereby this just requires light-emitting component (bulb) highly versatile and is easy to change with a fairly large number of light-emitting component (bulb).But along with the global resources supply is becoming tight, energy availability and demand contradiction becomes increasingly conspicuous, and causes energy prices to skyrocket, and illumination cost increases suddenly.The light-emitting component that can satisfy the various low energy consumption of illumination needs arises at the historic moment, use more relatively light emitting diode (Light EmittingDiode at present, usually be called for short LED), its operation principle is to utilize the material of luminous disome: III-V group element compound just forms the semiconductor with P-N composition surface on monocrystalline.Apply Vcc voltage by the outside, electronics is combined with electric hole when reaching thermal balance, superfluous energy can directly disengage with the form of light.Need the professional but it is installed and used, and be not identical concept between the traditional bulb, in same lighting device, do not have versatility, can not exchange.

No matter adopt the illumination of which kind of light-emitting component (bulb), present stage nearly all is to adopt the external power supply power supply, except some special places, more as public places such as market, movie theatre and so on as high residential building passage, basement, mine and some personnel, other is equipped with outside the emergency light of band self-contained battery power supply, and seldom use in other place.Reason has two: one, and existing emergency light only uses under power down mode, and installation is changed the personnel that need possess professional knowledge and finished; Two what adopt under the state of commercial power supply is another set of lighting device, this just caused lighting device repeat be provided with, increased the cost of illumination, produced unnecessary waste.Night, room lighting was when running into when having a power failure, owing to emergency light can be set usually, people's very inconvenience of living in the dark dare not arbitrarily be walked about, and hinders in order to avoid damage to hang.For addressing this problem, it is power autonomous that the someone has adopted same set of lighting device can use external power supply can use again.As Chinese patent notification number CN201054843Y, a kind of " LED meet an urgent need sense light " disclosed, be electrically connected reduction voltage circuit, stand-by power supply and power supply switch circuit by LED lamp, human inductor, step-down rectifying circuit, city and form, (LED) is single for its light-emitting component, though energy-conservation versatility is poor; It is strongly professional that replacing is installed, and the ordinary people can't be competent at; Its structure can't with interior decoration light fixture compatibility, thereby be mainly used in outdoorly, its scope of application is narrower.

Summary of the invention

The purpose of this utility model be to overcome above-mentioned shortcoming and a kind of highly versatile of providing, install change easily, structure energy-saving emergency lamp small and exquisite and applied widely.

Energy-saving emergency lamp of the present utility model comprises metal-back lamp holder, Lamp cup, and lamp holder is fixed on the Lamp cup bottom, and wherein: stand-by power supply and light-emitting component are fixed on the mainboard (realizing the circuit board of required circuit of function and element), and mainboard is fixed in the Lamp cup.

Above-mentioned energy-saving emergency lamp, wherein: the metal-back shell of lamp base is provided with external screw thread.

Above-mentioned energy-saving emergency lamp, wherein: stand-by power supply is disposable battery or rechargeable battery.

Above-mentioned energy-saving emergency lamp, wherein: light-emitting component is one or both combination of energy-saving light-emitting components such as CFL electricity-saving lamp or LED.

Above-mentioned energy-saving emergency lamp, wherein: Lamp cup is provided with lampshade.

The utility model compared with prior art, as can be known from the above technical solutions.The conventional lamp holder (as: screw thread mouth formula) that lamp holder is general, making between this bulb and present the most widely used incandescent lamp or the electricity-saving lamp can mutual alternative, so this bulb is applicable to all types of lamp sockets.Highly versatile is installed simultaneously and is changed easily, thereby applied widely.Circuit and the element of realizing required function are integrated on the mainboard, neither need to take more spaces, make bulb more small and exquisite, make that also its assembling is very easy simultaneously, be easy to large-scale production, thereby reduced production cost.Adopt energy-conservation light-emitting component, to reach energy-conservation effect.Adopting dual power supply simultaneously is stand-by power supply (battery) and mains-supplied, and stand-by power supply is disposable battery or rechargeable battery, guarantees that bulb can use under power down mode, to satisfy emergent needs.

Below further specify the beneficial effects of the utility model by the specific embodiment.
