Abstract
The utility model relates to a light-variable electric torch. Two gears of slide switches K are arranged on the front end of an electric torch shell 1. A one gear contact 9 of the switches K can lead a reduction voltage component 3 of copper sheets 5, 6 which are connected with the base 4 of the switch to be connected in series with an illuminating circuit. The contacts 2, 9 of the switch K can lead the reduction voltage component 3 to be connected in parallel with the illuminating circuit. The two gear switch can realize the strong and weak conversion of the electric torch to adapt to requirements in different places. The service life of bulbs of electric torches can be greatly prolonged.
Description
The utility model is relevant with flashlight.
Traditional flashlight contacts with the copper sheet of switch base by the contact of the slide switch on the barrel shell, and whole voltages that battery is exported directly are added on the bulb, are fixed the light of state only, can not be fit to need to use the needs of low light level occasion.New battery or firm charged dry cell voltage all are higher than the torch bulb normal voltage, very easily burn out torch bulb, owing to generally do not have standby torch bulb, flashlight are usually lost efficacy when emergent the use.
The purpose of this utility model provides the adjustable flashlight of a kind of brightness.Another purpose of the present utility model is the service life that prolongs torch bulb.
The utility model is equipped with two retaining slide switch K at the front end of torch shell 1, one retaining contact 9 of K switch can be inserted voltage drop element 3 series connection that connect the copper sheet 5,6 of base 4 in the lighting circuit of torch, and the contact 2 of K switch and 9 can be with voltage drop element 3 in parallel accesses in the lighting circuit.
Switch pedestal 4 of the present utility model is fixed on the torch shell 1, is fixed with copper sheet 5,6,7 on the base 4, and copper sheet 5,7 is connected with photograph circuit two ends, copper sheet 6 and copper sheet 7 insulation.Be connected with voltage drop element 3 between the copper sheet 5 and 6.Be fixed with copper sheet 8 on the slide switch K, contact 2,9,10 is arranged on the copper sheet 8.
Voltage drop element 3 of the present utility model is dropping resistor R or diode D.Also many of series connection of voltage drop elements.
When two retaining slide switches of the present utility model are shifted a gear onto and put, lighting circuit can be inserted with the voltage drop element series connection in the contact, and battery E provides the cell voltage that has reduced by voltage drop element to bulb, and bulb sends the low light level; When switch continued to be advanced to second gear and puts, the contact was directly connected circuit and voltage drop element is in parallel with the switch copper sheet, and this moment, bulb obtained whole voltages of battery E, and bulb sends stronger light.The utility model adjustable brightness can adapt to the needs of different occasions; When using new battery or just charged battery, can put use at a gear, avoid burning out bulb.The utility model is simple in structure, and is easy to use, long service life.
Fig. 1 is an overall construction drawing of the present utility model.
Fig. 2 is the I partial enlarged drawing of Fig. 1.
Fig. 3 is circuit theory diagrams.
Embodiment:
Torch shell 1 of the present utility model is equipped with base 4.Be fixed with copper sheet 5,6 on the base 4,7.Copper sheet 5,7 is connected with the lighting circuit two ends.Copper sheet 5,6 connects by dropping resistor 3.Base 4 has chute and two retaining slide switch K to be slidingly matched.Copper sheet 8 is fixed on the K switch.Contact 2,9,10 is arranged on the copper sheet 8.Contact 10 contacts with copper sheet 7.In the closed position of K switch, contact 2,9 lay respectively at copper sheet 5 and 6 and copper sheet 6 and 7 between the space.Gear in K switch is put, and the resistance R string was pressed into lighting circuit when contact 9 contacted with copper sheet 6.Two gears in K switch are put, and contact 2 contacts with copper sheet 5, make resistance R in parallel with copper sheet 8.There is hand switch 11 slide switch K end.
