Abstract
The utility model relates to a long-life bulb, which is composed of a filament, a stem, a lamp cap, a semiconductor diode, a lead-out contact, and a glass shell, wherein, the semiconductor diode is encapsulated in the lamp cap outside the vacuum glass shell of an incandescent bulb, and the semiconductor diode is connected in series with a tungsten filament on electrical connection, so the impact current of the bulb is largely reduced. The utility model has the advantages that the technology is simple; the cost is low; the operation is convenient and safe; the service life of the bulb can be increased by more than ten times. The utility model can be widely used in the places where the switch is used frequently.
Description
The utility model relates to a kind of Life-prolonging electric bulb, belongs to the incandescent lamp technical field.
The average life span of ordinary incandescent lamp bubble is about 1000 hours.Its modal damage is that filament is blown, and particularly in some public places, locates as dormitory corridor, public lavatory etc., because bulb switch continually, filament bears very big starting current, easier burning.Therefore, in order to prolong bulb service life, the starting point of people's thinking considers to increase standby filament often in bulb.For example, recognize through the Searches of Patent Literature, at number of patent application is 87206581, name is called in the patent application of " Life-prolonging electric bulb ", has proposed a kind of Life-prolonging electric bulb, and it is newly-increased one group of filament on former bulb core-column, one group of contact of many welderings at the lamp holder top, after one group of filament is damaged, transfer contact, another group filament can use.And for example, at number of patent application is 91204666, name is called in the patent application of " durable incandescent lamp bulb ", a kind of incandescent lamp bulb has been proposed, filament is by forming with many standby filaments in usefulness, have on the lamp holder and the joining nut of standby filament, during with standby filament, only need getting final product in the nut on the corresponding screw screw-in lamp holder.Though more than these methods can prolong bulb life, production technology is complicated, and since when opening the impulse current on the filament do not reduce, so the method for the standby filament of this employing can only prolong bulb life one to several times.
The purpose of this utility model is to overcome the deficiencies in the prior art part and provides a kind of technology simply can make the longer Life-prolonging electric bulb of bulb life continuity.
The purpose of this utility model can reach by following measure:
The utility model by filament, stem stem, lamp holder, semiconductor diode, draw the contact, glass bulb is formed, in the lamp holder of semiconductor diode package outside the incandescent lamp bulb glass bulb, one end of diode is welded on the lead-in wire of filament, the other end of diode is welded on of lamp holder and draws on the contact, and another of lamp holder drawn the contact and linked to each other with another root lead-out wire of filament.
Electrical connection diagram as shown in Figure 3.Owing to increased a semiconductor diode in the lamp holder, according to semi-conductive forward voltage-current characteristic, as shown in Figure 4, at voltage is 0 o'clock, semiconductor resistor is bigger, be about more than 600 ohm, and the tungsten filament resistance of cold conditions, tungsten filament resistance as 60 watts of incandescent lamp bulbs is about 60 ohm, that is to say, when diode with after tungsten filament is connected, the moment resistance of energising has increased more than 10 times, compare with the situation that does not add diode, the starting current of filament is less than original 1/10th, like this with regard to having significantly reduced because the impulse current when turning on light and with the possibility of disintegration of filament.When voltage is increased to 0.6 volt when above, diode is conducting fully just, and its resistance is tending towards 0, and for the tungsten filament that resistance more than 60 ohm is arranged, the forward resistance of diode can be ignored fully.In addition, because sealing in of diode converted alternating current to pulse direct current, make the operating current of bulb also reduce half, like this, when bulb added rated voltage, because load reduces, bulb life will increase; When on the bulb during institute's making alive overrate, also be not easy to damage.
The utlity model has following advantage:
1, technology is simple, and production cost is low; Easy to use, safe and reliable.Get final product owing to only need before the encapsulation lamp holder, in lamp holder, increase a semiconductor diode, than increasing the simple in structure of cover filament of Duoing.Use the time image common bulb the same, do not need transfer contact.Rated voltage is that the bulb of 220V can tolerate up to the voltage of 250V and do not damage.
2, the utility model is compared with existing bulb, and can increase more than ten times useful life.
The drawing explanation of accompanying drawing:
Fig. 1 and Fig. 2 are respectively the installation situation of the utility model in screw socket bulb and socket bulb.
Fig. 3 is the method for attachment schematic diagram of diode of the present utility model and tungsten filament.
Fig. 4 is the forward voltage-current characteristic of diode.
Now in conjunction with the accompanying drawings embodiment of the present utility model is illustrated:
As Fig. 1, the utility model embodiment by filament (1), stem stem (2), lamp holder (3), semiconductor diode (4), draw contact (5,7), glass bulb (6) is formed, semiconductor diode (4) is encapsulated in the outer lamp holder (3) of incandescent lamp bulb glass bulb (6), one end of diode is welded on the lead-in wire of filament at the A place, the other end of diode is welded on of lamp holder and draws on the contact (5), and another of lamp holder drawn contact (7) and linked to each other with another root lead-out wire of filament.
Used diode model is 1N4007 among the utility model embodiment.
The wattage of Life-prolonging electric bulb is four kinds of 20W, 30W, 50W and 100W, and is as shown in the table corresponding to the original employed tungsten filament of bulb:
| Use tungsten filament power 40W 60W 100W 200W | Life-prolonging electric bulb wattage 20W 30W 50W 100W |
