Abstract

The utility model relates to an incandescent lamp bulb belonging to the technical field of illumination. The utility model solves the problem that the service life of an incandescent lamp which is turned on throughout the night is short. The utility model is composed of a lamp cap (1), a leading wire (2), a lamp filament (3), support frames (4) and a glass shell (5). The utility model is characterized in that the length of the lamp filament (3) is lengthened; the angle between the support frames (4) is enlarged; the length of the original lamp filament in a spiral rolling mode is equal to 48 millimeters, and the length is lengthened by 53.5 millimeters; a circular arc in which the lamp filament (3) is positioned is enlarged by 267 DEG from 240 DEG. The utility model is widely used in places where a lamp bulb is easily burnt in public places, such as a place where a road lamp is positioned, a corridor, a place where a power supply indicator is positioned, a place where a polychromy is positioned, a public lavatory, etc.

Description

A kind of incandescent lamp bulb

The utility model is a kind of incandescent lamp bulb.

The utility model belongs to the incandescent lamp bulb lighting technical field.

Incandescent lamp bulb has been subjected to user's favorable comment for many years because its simple installation, price are low, not can both throw light on by the low restriction of voltage.But, to the place of illumination between often, as public lavatory, corridor, street lamp, distribution indication, the rear taillight etc. that turns to, brakes of ornamental festoon lamp vehicular traffic, useful life, weak point was the subject matter of solution." look into eelctrical engineering handbook and know that it is " to look into rural area electrotechnics question and answer volume two in 1000 hours that ordinary incandescent lamp bubble uses under rated voltage, chapter 8, illumination and other electrician's knowledge are known, when supply voltage has surpassed bulb rated voltage 5%, bulb life will reduce half ".For solving the short problem of service life of incandescent lamp, the use of contacting of two identical wattage bulbs of human is arranged, also have the people with the transformer step-down or in the circuit crosstalk hinder, these ways can prolong the life-span of bulb, but trouble is installed, dangerous, a little less than polyphone uses light too, and two of a bulb damage does not all work.

The purpose of the utility model design is, and is the same with original incandescent lamp bulb external form, need not polyphone, need not to increase any annex, obtains bearing the voltage height, the purpose of long service life.

The technical solution of the utility model is: on the basis of original bulb, improve the voltage design, make its discontented pressure operation.According to the length of the tungsten filament that how much extends that improves voltage, improved the rated voltage of bulb like this owing to the lengthening of osram.As using on former rated voltage, though power descends to some extent, the life-span of bulb is compared corresponding raising of life-span with voltage Gao Shiyong.In order to make bulb in use certain power can be arranged, how much this will determine according to the applied voltage peak value the concrete lengthening of osram.Example: when civil power 220V, 10000 volts of inputs of transformer, the line pressure of output is 400V, and phase voltage is 231V, during peak of power consumption, the electricity consumer multiple current is big, and line drop is also big, bulb voltage is generally below 220V, be difficult for burning, during low ebb, the line voltage height, sometimes reach 10500V, then the line voltage of transformer output is 420V, and phase voltage is 243V, so be the main cause of burning normal bright lamp in evening.We improve 11.4% and 20% with the rated voltage 220V of bulb, and the rated voltage of bulb is 245V and 264V just, occur the bulb of three kinds of voltages on the market, and the user can select to use a kind of according to the situation of local voltage peak.Automobile-used bulb improves voltage 16.5% and changes 7V, 14V, 28V into by original 6V, 12V, 24V.

The production technology of the utility model incandescent lamp bulb is the same with the production technology of former bulb as long as press the percentage that improves rated voltage on the basis of former bulb, calculate the length of lengthening filament, slightly change the structure of filament support, the filament of lengthening can have been loaded onto just, so realize easily.

The utility model is compared with background technology, the long characteristics of voltage high life of bearing are arranged, the user can be according to using local difference to remove to select the bulb of a certain voltage, (as the high place of changing inconvenience of voltage, not having the public place of professional people's management) uses the utility model can obtain reducing the purpose of repairing.

Description of drawings of the present utility model is as follows:

Figure (1) presses the vertical view of 245V design for the utility model 100W.

Figure (2) is the vertical view of former incandescent lamp 100W220V.

The incandescent lamp bulb that it is made up of lamp holder (1), lead-in wire (2), filament (3), support (4), glass shell (5) respectively.From the contrast of figure (1), figure (2) as can be seen, because of the lengthening of figure (1) filament, so the support of anchored filament and lead-in wire garden radian add greatly 267 ° by original 240 °.

The best way of the utility model practice is, on the basis of former bulb rated voltage, according to the percentage that improves voltage, obtains the resistance value of increase, calculates the length of filament, changes the filament support structure according to the total length of filament, filament fixed get final product.With the 100W220V bulb is example: former filament length of run is 663 millimeters, long 48 millimeters of spiral shell volume; Utility model is pressed the design of 245V voltage, and filament launches the long 663+ (663 * 11.4%)=739 that is, the spiral shell volume is long for 48+ (48 * 11.4%)=53.5 millimeter.So the radian of anchored filament support is by (2) 240 ° of 267 ° of changing figure (1) into of figure; Slightly the length that changes lead-in wire (2), support (4) can be put into practice.

Claims

1, a kind of incandescent lamp bulb of forming by lamp holder (1), lead-in wire (2), filament (3), support (4), glass shell (5), it is characterized in that: the length of extended filament (3), strengthened the angle between the support (4), filament is 53.5 millimeters by the long 48 millimeters lengthenings of original volume, and filament (3) is placed circular arc and added greatly 267 degree by 240 original degree.
