Abstract
The utility model relates to a power illuminating appliance which is especially suitable for illuminating device frequently using small-power lamp bulbs to effectively prolong the service life of the lamp bulb. The utility model is mainly composed of two tungsten filaments and a resistance wire; when one tungsten filament lies in an operating state, the other tungsten filament lies in a standby state; when the tungsten filament lying in the operating state is burnt, the standby tungsten filament is switched on to start working because of the action of the resistance wire. The utility model is mainly suitable for small power lamps of vehicles, various instruments, indicating lamps of instruments, miners lamps, lamp bulbs of electric torches, etc.
Description
What the utility model was related is the power supply lighting apparatus, particularly is suitable for the lighting device higher to the small-power frequency of utilization, the useful life of improving bulb effectively.
The low-power bulb of selling on the existing market or using all is made up of a tungsten filament, insulation magnetic core, cell-shell etc., owing to be a tungsten filament, bulb service life is shorter, when tungsten filament blows just unrenewable, only be that tungsten filament blows, make whole bulb unrenewable, both wasted material resources, useless bulb has polluted environment again.
The purpose of this utility model is: the bulb that the two tungsten filaments of a kind of small-power are provided, it can make the bulb secondary use, save a large amount of raw material, reduce environmental pollution, mainly be applicable to vehicles small-power lamp, each quasi-instrument, used indicator light, mine lamp and the torch small electric bulb etc. of instrument.
Task of the present utility model is following finishing: draw a standby Dumet wire in bulb insulation magnetic core, tungsten filament on Dumet wire is connected with another root tungsten filament one end, joins at a standby Dumet wire stage casing resistance wire of connection and another root Dumet wire that the insulation magnetic core is drawn.When circuit debugging, at first connect the path of one road tungsten filament, because the effect of resistance wire, another road tungsten filament can't be worked, when blowing, resistance wire connects standby Dumet wire in another road and tungsten filament because the voltage difference is breakdown when the road tungsten filament that uses is aging, continue operate as normal, reached a bulb and prolonged secondary useful life.
The utility model advantage is: one, save material, the two tungsten filaments of bulb can be worked as two uses, have reduced customer using cost; Two, reduce of the pollution of useless bulb to environment.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is the utility model schematic diagram;
Fig. 2 is the utility model line map;
According to shown in Figure 1, the utility model also has Dumet wire 2,3,8 etc. to form by cell-shell 1, two tungsten filaments 5,7 and resistance wire 4, insulation magnetic core 6.Drawing standby Dumet wire 8 upper end tungsten filaments 7 in bulb insulation magnetic core 6 is connected with another root tungsten filament 5 one ends, connecting a resistance wire 4 in standby Dumet wire 8 stage casings that insulation magnetic core 6 is drawn joins with another root Dumet wire 2, when circuit debugging, pass through tungsten filament 5 to Dumet wire 3 by Dumet wire 2, forming loop, a tungsten filament 5 starts working, standby tungsten filament 7 has been blocked its path, and has been in stand-by state owing to the effect of resistance wire 4.When blowing when wearing out after tungsten filament 5 long-time the uses, resistance wire 4 has been connected standby tungsten filament 7 because the voltage effect is breakdown, makes Dumet wire 2 arrive Dumet wire 3 another loops of formation to Dumet wire 8 by tungsten filament 7, and tungsten filament 7 is started working.It is between 0.06～0.25A that tungsten filament 5,7 is suitable for electric current, and voltage is between 1.5～24V.The general diameter of the scope of application of its resistance wire 4 is between 0.07～0.10mm, and puncture voltage is between 20～100V.
