Description
Technical field
The present invention relates to lighting lamp, belong to the automatically technical field of control of emergency lighting, specifically it is a kind of LED Emergency daylight lamp, and it is particularly suitable for the place that factory, office, school, hospital etc. need general emergency lighting, can greatly strengthen the quality of general lighting.
Background technology
We know, because the LED fluorescent lamp in use has energy-conserving and environment-protective and the colory remarkable characteristic of light source, at present, it has generally been accepted and be widely used in numerous industries and has been used for work, studying and living illumination by people.Its basic structure and operation principle are: it is to consist of fluorescent tube by semicircle heat radiation shell, semicircle printing opacity shroud and LED lamp bar substrate, and in the tube head of fluorescent tube, be equipped with the Switching Power Supply pcb board, can be converted into the 12V direct current to the power supply of LED lamp bar substrate and make the luminous illumination work that carries out of LED lamp sequin by the civil power of switching power circuit with 220V/50Hz.Although existing LED fluorescent lamp is as lighting, it has really, and illuminating ray is soft, the working stability noiselessness, save the advantage of electric energy clean environment firendly and long service life.But we also find in the long-term production R﹠D process: the function of existing LED fluorescent lamp product is comparatively single, without emergency function.At present, the power outage of reply electrical network burst, general all or adopt the conventional approach that is equipped with generator or emergency light equipment is installed in addition to solve the temporary lighting problem.Need not to dare not or would not speak up, a kind of interim power supply remedial measure that has a power failure and take is later just occuring in this, it is emergent ageing or relatively poor for the burst grid power blackout accident state of emergency, because grid power blackout exists sudden and uncertainty power off time, if the emergency measure of taking is untimely, bring for society and politics, cultural economy and orders of life to have a strong impact on and cause heavy losses to the security of the lives and property, this is present responding agencies problem in the urgent need to address.Can on existing LED fluorescent lamp basis, increase again emergency function? this is that existing LED fluorescent lamp also requires further improvement and improve the place, and the present invention also wants to solve this problem just.
Summary of the invention
The objective of the invention is on the basis of existing LED fluorescent lamp technology, to propose a kind of LED Emergency daylight lamp with emergency function.It is to increase a storage battery power supply pattern on the basis of mains-supplied pattern again, it can switch to immediately in the moment of grid power blackout storage battery power supply pattern continuation power supply and keep illumination, people are difficult to feel to have in actual use high emergent aging performance by the sign that cuts off the power supply in handoff procedure.
The objective of the invention is to realize according to following technical scheme:
A kind of LED Emergency daylight lamp, it comprises fluorescent tube and is fitted to the left tube head of lamp tube ends, right tube head, said fluorescent tube is made of dispel the heat shell, semicircle printing opacity shroud and LED lamp bar substrate of semicircle, in right tube head, be fitted with the PCB circuit board that switching power circuit is set, it is characterized in that: be provided with control switching circuit at the PCB circuit board, said PCB circuit board fixedly is fitted in the draw-in groove of right tube head inwall setting, be fitted with battery in left tube head, two core cables of battery are connected in control switching circuit.It is performed such normal illumination and emergency lighting: the tube head insertion of fluorescent tube is connected in the lamp socket of 220V/50Hz civil power, behind the civil power importing PCB circuit board of the lamp base on the tube head with 220V/50Hz, convert the supply led circuit substrate work of 12V direct current to and make luminous illumination of LED lamp sequin by the civil power of switching power circuit with 220V/50Hz again, its control switching circuit is to design according to the following rules and control work: 1. civil power normal power supply pattern: when the electrical network normal power supply, switching power circuit converts the civil power of 220V/50Hz to the 12V direct current and makes the luminous illumination work that carries out of LED lamp sequin to the power supply of led circuit substrate.Simultaneously, can behind the full electric energy of storage, stop voluntarily charging to charge in batteries and at the charge and discharge state of controlling battery under the monitoring of control switching circuit; 2. battery emergency service pattern: when the electrical network burst had a power failure, control switching circuit was switching to battery emergency service pattern immediately, continued power supply by battery to the LED Emergency daylight lamp and kept illumination; 3. when treating the power system restoration normal power supply, control switching circuit switches again the civil power normal power supply pattern that reverts to immediately, and at this moment the LED Emergency daylight lamp recovers again the normal power supply pattern of throwing light on civil power.Need to prove: the LED Emergency daylight lamp that the present invention proposes is to finish moment to the handoff procedure of two kinds of powering modes.In fact, people are difficult to aware any outage sign that switches moment, and it has high emergent aging performance in actual use.
For realizing better technique scheme, say that further the present invention also has following technical characterictic:
Tube wall at right tube head is provided with one group of electric source modes demonstration hole, is fitted to one group of electric source modes and shows that the glory diode in the hole is connected in control switching circuit.Can select red, green, yellow three kinds of glory diodes to show that respectively the mistake of mains-supplied pattern, storage battery power supply pattern and battery puts, overcharges state.
Tube wall at left tube head, right tube head is respectively arranged with one group of heat radiation groove.The heat that it can be in time produces power device distributes in the tube head and discharges, and this has obvious effect to the work quality that prevents that tube head is overheated, stablize electrical equipment service behaviour and raising LED Emergency daylight lamp.
Said battery is supported on support and fixedly is fitted in the left tube head with heat conductive silica gel, and two core cables of battery are that the semicircle radiating tube that passes fluorescent tube is introduced in the right tube head and is connected in control switching circuit.Can improve the installation stability of battery in left tube head, guarantee that battery charge and discharge stable working and increasing storage battery service life have certain effect.
Described battery is that rated voltage is that DC12V, electric energy reserves are the lithium battery of 1000mAh, and control appearance and size is 48 * 22 * 16mm.Select this battery can guarantee that the emergency service time more than 2 hours, has fine emergent effect.
The present invention compares with prior art and has following outstanding substantive distinguishing features and marked improvement:
The present invention has initiated the layout mounting structure of inserting control switching circuit and equipped battery in existing LED fluorescent lamp tube head, it is to increase emergency function on the basis of existing LED fluorescent lamp normal illumination, has effectively expanded the use function of common LED fluorescent lamp product.It has modern design, produce easy low cost of manufacture, ageing strong remarkable advantage easy to install, safe and reliable to operation, emergent.It is particularly suitable for factory, office, school, hospital etc. needs the place of general emergency lighting to use, can when electrical network happens suddenly power outage, automatically switch to rapidly the emergency service pattern and keep illumination, the quality of common LED fluorescent lamp can greatly be optimized and strengthen to enhancing to the emergency capability of burst power failure emergency situation.
