Description

Energy-conservation superbright velocitron

The fluorescent lamp that the utility model relates to a kind of Design of Luminaires technology, particularly a kind of 3W-30W of utilization is made the energy-conservation superbright velocitron of light emitting source, and the fluorescent light fixture, desk lamp, wall lamp or the emergency luminaire that can be used as various patterns use.

At present, often having a power failure and lacking the place of supply of electric power, people press for the indoor and outdoor can both the logical light fixture of the big light of lighting for a long time.Therefore once generally used light fixtures such as gas lamp, barn lantern in power free rural area, gas lamp, these light fixtures of barn lantern are fallen behind superseded already.The existing emergency light that uses also has three big shortcomings: brightness is not enough; crash time is not long; be not durable, few (can only work as emergency light uses function; can not work as conventional light fixture uses); discharge and recharge poor safety performance; its control circuit does not possess storage battery and fills the full cut-out that stops, using up, and realizes the function of self-protection, causes the life of storage battery short.

The purpose of this utility model provides a kind of energy-conservation superbright velocitron, and it can be worked as ordinary lamp and lantern and emergency luminaire and uses, and make have energy-conservation, prolong and light the time and prolong storage battery useful life.Have in addition after as long as the storage battery electricity consumption is lower than rated voltage, external power just charges again and again up to filling full stopping.

The utility model is to adopt following technical scheme to realize: the same with other emergency luminaires or chargeable electricity-saving lamp, it still comprises lamp housing, lamp socket, fluorescent tube (fluorescent lamp), as the storage battery E that provides emergency power supply for oneself, transformation (device) rectifier (circuit), charging control (device) circuit and high-frequency generator formations such as (circuit) is characterized in that (with reference to Fig. 2):

A, in the charge controller circuit, have additional in the set normal charge circuit by voltage stabilizing (two utmost points) pipe Z ₁With triode D ₁, D ₂, D ₃It is the guard's valve circuit that the limited pressure that constitutes fills full, wherein, and voltage-stabiliser tube Z ₁An end and storage battery E positive pole join its other end and triode D ₁Base stage join D ₁Collector electrode and D ₂Base stage join D ₂With D ₃Form composite amplifier, when in charging, voltage stabilizing didoe Z ₁Be in collapse district's work (resistance minimum, current lead-through), make triode D ₁, D ₂, D ₃Conducting, LED ₁The indication charge, when storage battery E fill full, when both end voltage is raised to maximum prescribed value (as 14.5V or 16.5V), voltage-stabiliser tube Z ₁Enter active region (resistance maximum) and form off state, D ₁, D ₂, D ₃Not conducting, charging stops, LED ₁Lamp goes out.

B, in the charge controller circuit, also be provided with by relay J, switch triode D ₆And be used to control D ₆The voltage stabilizing of conducting or shutoff (two utmost points) pipe Z ₃The limited pressure automatic switch-over circuit of forming, when providing storage battery E work for oneself, Z ₃Conducting (resistance minimum), D ₆Conducting, the normally opened contact JK closure of relay J has electric current output (for lamp works) on the circuit, when storage battery E voltage drops to minimum regulatory value (as 10.5V or 12.5V), Z ₃Enter the active region, form off state (resistance increase), at this moment D ₆Not conducting, the coil of relay J be electricity only, and relay contact switch JK jumps out of automatically, can cut off the electric current output (LED of storage battery automatically ₂Light the indication inductive charging).

Below being aided with accompanying drawing is described in further detail concrete structure of the present utility model and circuit working principle.

Fig. 1 is the circuit block diagram of the utility model velocitron.

Fig. 2 is the electrical schematic diagram of the used charge controller of the utility model.

Fig. 3 is the circuit theory diagrams of a kind of oscillator when using 9-30W in the utility model.

Fig. 4 is the structural representation that the utility model system is gas lamp formula light fixture.

Wherein: 1-fluorescent lamp, 2-storage battery E, the 3-switch SW of turning on light ₁, 4-turn off switch for lamp SW ₂, 5-lamp housing, 6-transformer, 7-charge controller (circuit board).

With reference to accompanying drawing as can be known, the utility model also has following technical characterictic when specific design is made.

One, its HF link of described oscillator is designed to be defeated by the honeybee threshold voltage of fluorescent lamp greater than 900 volts, frequency of oscillation is the 40-50 kilohertz, when wherein fluorescent lamp is used 3-9W, winding number 35 circles when the elementary line of oscillator coil winding slightly is φ 0.44mm, the thick φ 0.25mm of secondary line, winding number 260 circles (circle), when fluorescent lamp was used 9-30W, elementary line slightly was φ 0.69mm, winding number 40 circles, the thick φ 0.25mm of secondary line, winding number 260 circles.Adopt the said structure circuit, the brightness of fluorescent tube is remained the same from beginning to end when having guaranteed illumination, and has overcome the 50Hz stroboscopic of common fluorescent lamp, and when battery tension dropped to 10V, oscillator still can 11-13 times of pressure-raising build-up of luminance.

Two, in the high-frequency generator circuit, the secondary two ends of its coil windings are single line with the two ends of fluorescent lamp (selecting the 3-30W specification for use) respectively and join to constitute the circuit structure that the corresponding electric shock in two ends is vibrated, build-up of luminance and electric shock are once finished, guaranteed that light fixture is bright once opening, avoided the 50Hz stroboscopic of ordinary lamp and lantern again.

Three, the utility model lamps and lanterns of electron appearance style can be made into the structure of emergency light formula, desk lamp type, barn lantern formula, gas lamp formula, wall-hanging and Focusing projective light formula, so that adapt to room lighting, writing or outdoor mobile operating needs.

With reference to Fig. 2, in the electrical schematic diagram of charge controller, voltage stabilizing (two utmost points) pipe Z ₂With triode D ₄, D ₅Be to be used to control LED ₂When being lower than setting, battery tension just should light indication inductive charging, at this moment Z ₂Be in collapse district (conducting), when storage battery is under normal circumstances powered, Z ₂Enter active region (not conducting).

Energy-saving design of the present utility model can make the limited electric weight of self-contained storage battery extend working time (light fixture of comparable prior art (as emergency light) prolong 70% light the time), storage battery according to the configuration of different time needs, can make from the light fixture of lighting 5-15 hour different size, can compare favourably with the brightness (luminous flux) of the above incandescent lamp of 60W.Compared with the prior art, emergent automation has fully been used in electronic control circuit design of the present utility model: when connecting external power, can directly use external power, when dispatch from foreign news agency is interrupted suddenly, again can the utmost point automatically switch in the short time connect power autonomous, can recover to use dispatch from foreign news agency during the outside line incoming call again, and stop up to filling to satisfy from the trend charge in batteries simultaneously.The utility model can protected charging and discharging of accumulator safety all the time, when the voltage of storage battery is lower than 12.5V (or 10.5V), and the automatic tripping protection of controller, and bright little red light (LED ₂) remind and charge.As charge in batteries (LED ₁Light) when reaching 14.5V (or 16.5V), controller cuts off charging again and extinguishes little red light LED ₁Therefore fill fullly to show, can effectively prolong useful life of storage battery, reach synchronous durable purpose with other parts of light fixture.
