Abstract
The utility model relates to a lamp for repairing vehicles, which is composed of a casing, a lighting lamp, an accumulator and a control system, wherein, the control system comprises a charging circuit and a lighting circuit. The utility model can be externally connected with a direct current power supply of 12V to 24V, with no difference between the positive and the negative voltages. The voltage is reduced to 3.6V after rectification and voltage stabilization. Meanwhile, the current is controlled below 150mA to charge an accumulator in the mode of trickling charge. The charging time is unlimited. The utility model has the advantages of beautiful appearance, small volume, large lighting radiating surface and convenient operation and portability. The utility model not only can be used for repairing various vehicles and devices at night, but also can be used as an emergency lamp during power failure.
Description
The utility model belongs to lighting device, is specifically related to a kind of portable vehicle maintenance lamp that has charging system.
The illuminating lamp that is used for car inspection and repair at present has fixed and stay-supported, uses on this class lamp distance to be restricted, and oversize as if what lead was drawn, operation can be dangerous, brings some inconvenience to use.Repairing lighting in the driving way generally all uses flashlight, though flashlight is easy to use, because light is concentrated, radiating surface is little, can only be used for local lighting.Other uses flashlight also to need often to change battery.
The purpose of this utility model provides that a kind of volume is little, the lighting radiation face is big and have the portable vehicle maintenance lamp of charge function.
The utility model car inspection and repair lamp is made up of housing, illuminating lamp, battery and control system.Be provided with dividing plate in the housing, the dividing plate both sides are placed battery and control system wiring board respectively, and Illumiuating lamp socket is fixed on housing one side by screw, and end cap is positioned on the lamp socket.
Control system comprises charging circuit and lighting circuit, and charging circuit and lighting circuit are parallel to the battery two ends, and charging circuit comprises bridge rectifier, voltage stabilizing, current limliting electric power storage and charging display part, and wherein the current limliting storage circuit is by commutation diode D
1, resistance R
1Form, the charging display circuit is by light emitting diode D
2, resistance R
2Form.Lighting circuit comprises illuminating lamp and switch.
During charging, be regardless of the dc source of positive and negative external 12V～24V, after rectification, voltage stabilizing, be depressured to 3.6V, through resistance R
1Current Control below 150mA, is carried out trickle charge to battery.During illumination, by switch control lighting bulb.
Further describe the utility model below in conjunction with accompanying drawing:
Fig. 1 is the utility model profile schematic diagram.
Fig. 2 is the utility model structural representation.
Fig. 3 is the vertical view of Fig. 1.
Fig. 4 is the control system circuit theory diagrams.
