Abstract
The utility model provides a non-powercut stroboflash-free illumination desk lamp. An output end conducting wire of a rectifier is connected with a lamp tube after being connected in series with a high-frequency converter, and the other output end conducting wire of the rectifier is connected with a high-frequency inverter after being connected in series with a charging device, a battery and a unilateral diode. When the non-powercut stroboflash-free illumination desk lamp is used, an input circuit realizes the lamp tube illumination through the rectifier via the high-frequency inverter, and simultaneously, the battery is charged. Because the unilateral diode is connected between the battery and the high-frequency inverter, the power supply of the battery can always supply electricity to the high-frequency inverter, the power supply supplied by the rectifier to the high-frequency inverter cannot flow to the battery, and the electricity is supplied to the lamp tube for illumination through the diode and the battery connected with the high-frequency converter when the sudden power cut of the input circuit occurs. Because the unilateral diode is arranged between the battery and the high-frequency inverter, the rectifier and the battery always maintain the communication state with the high-frequency inverter, the battery continuously supplies electricity during the power cut, and the illumination of the non-powercut stroboflash-free state desk lamp can be reached.
Description
Technical field
The utility model relates to a kind of lighting lamp, a kind of specifically no stroboscopic illumination desk lamp that do not have a power failure.
Background technology
Employed various lighting lamps then can't use after power failure, in order not influence working and learning now; Much human all can be equipped with emergent desk lamp and use, but all there is the bad and heavy problem of illumination in existing emergent desk lamp, in the use very inconvenience; And minority producer is provided with reserve battery in lighting lamp, supply power through the desk lamp that switches to of battery, but when reality is used; Having a power failure and switching still exists a time difference, can have an outage phenomenon, still very inconvenient in the use.
Summary of the invention
The purpose of the utility model is to solve the deficiency of above-mentioned technical existence, and a kind of no stroboscopic illumination desk lamp that do not have a power failure is provided, can be when desk lamp use to meet with have a power failure, and what internal battery can not cut off the power supply and not have stroboscopic continues as the desk lamp powered lighting.
The utility model comprises rectifier, charger, battery, high-frequency inverter and fluorescent tube, and the technical scheme that is adopted is: after the output that has input circuit, rectifier connects high-frequency inverter through the lead polyphone, be connected with fluorescent tube; Another output of rectifier connects the front end that is connected high-frequency inverter behind charger and battery and the unilateral diode through lead polyphone.During user mode; Input circuit is the lamp tube power supply illumination through rectifier through high-frequency inverter, and simultaneously, rectifier is a battery charge through charger; Owing between battery and high-frequency inverter, be provided with unilateral diode; This unilateral diode can be to block between power supply and the battery of high-frequency inverter with rectifier, and battery can form unidirectional power supply with high-frequency inverter, and set unilateral diode can play battery can be to the unidirectional energising effect of high-frequency inverter; And rectifier directly can not lead to battery to the power supply of high-frequency inverter, and battery is only accepted the charging of rectifier through charger.
The utility model passes through technique scheme; Owing between rechargeable battery and high-frequency inverter, be provided with a unidirectional diode; Constitute rectifier and battery and all kept connected state with high-frequency inverter all the time; When lighting lamp meets with burst and has a power failure, battery since the connected state that is in all the time with high-frequency inverter can under the state that need not switch, supply power for desk lamp continuously; Can realize thus not having a power failure and do not have the desk lamp illumination of stroboscopic state, can be used as new technology and regeneration product is promoted the use of.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further to detail.
Accompanying drawing is the utility model block diagram syndeton sketch map.
Among the figure: 1, rectifier, 2, charger, 3, battery, 4, unilateral diode, 5, high-frequency inverter, 6, fluorescent tube, 7, input circuit, 8, lead.
Embodiment
Shown in the accompanying drawing embodiment: connect high-frequency inverter 5 backs at the output that has input circuit 7, rectifier 1 through lead 8 polyphones and be connected with fluorescent tube 6; Another output of rectifier 1 connects the front end that is connected high-frequency inverter 5 behind charger 2 and battery 3 and the unilateral diode 4 through lead 8 polyphone.
During practical implementation; The utility model package unit structure can be built in the lamp socket of desk lamp; Said fluorescent tube 6 can adopt power saving fluorescent lamps; Rectifier 1 is for becoming civil power 220VAC alternating current the controlled rectifier of 16VDC direct voltage, and charger 2 be battery 3 chargings simultaneously, and is that the high-frequency alternating current of 50KHZ supplies fluorescent tube 6 to throw light on through the contrary electrical equipment 5 of high frequency with the direct voltage inversion.
