Description

Power-saving, long-life sheet for screw shell incandescent lamp

The utility model is a kind of economize on electricity, the device for prolonging that provides for the screw type incandescent lamp.

The utility model economize on electricity, the principle of lengthening the life: behind device the utility model, equal semiconductor diode of series connection on incandescent lamp.Because the unilateal conduction performance of semiconductor diode, the electric current that flows through incandescent lamp bulb is exactly unidirectional Rectified alternating current, and filament two ends effective voltage is 1/2 of a supply voltage.This moment, filament electric consumption power was significantly smaller than the rated power of incandescent lamp bulb, and the luminous intensity of bulb also reduces simultaneously.But the amplitude that the amplitude that luminous flux reduces reduces less than the filament consumed power.Incandescent lamp bulb with 220V, 60W is an example, behind the series connection semiconductor diode, and the about 18W of actual power consumption, and the luminous flux that sends is equivalent to the luminous flux that common 25W incandescent lamp sends, and like this, just can obtain to save the power savings of 7W power.The reason that device the utility model is lengthened the life incandescent lamp bulb has 3 points: 1. because the effective voltage at filament two ends only is 1/2 of supply voltage, diode has internal resistance simultaneously, thereby temporary impact electric current (several times greatly of the common this temporary impact current ratio bulb running currents that form because of the filament cold-state resistance is little can stop incandescent lamp to be opened effectively the time, it is one of main reason that causes the incandescent lamp bulb damage), damage chance thereby reduce bulb; 2. to bear operating voltage be 1/2 of supply voltage at the filament two ends, also is 1/2 of former rated voltage, thereby can bear the variation that supply voltage very significantly raises because of a variety of causes, reduces bulb and damage chance; 3. because the operating voltage at filament two ends is 1/2 of a bulb rated voltage, it is also much smaller than former rated current to know the electric current that flows through filament by inference according to Ohm's law, so just reduce the speed of tungsten matter filament surface ion evaporation when work significantly, prolonged the normal useful life of filament.

About principle of the present utility model, analogue can be consulted the 2nd page of " external scientific and technological message " the 6th phase in 1986: the 7th page of " Life-prolonging electric bulb " literary composition and " electric era " 1987 the 1st phase: " simple and practical economic lamp " literary composition.

The purpose of this utility model is for using the screw type incandescent lamp bulb to provide a kind of easy to use, cheap economize on electricity, device for prolonging, the consumption of the power consumption of saves valuable and screw type incandescent lamp bulb.

Embodiment of the present utility model is very simple, only is a semiconductor diode (silicon, germanium material make all can) is installed on the megohmite insulant of approximate circle sheet, and its two end links with two contact electrodes respectively; Also semiconductor diode can be welded on the contact electrode, use the molten cast solid of megohmite insulant (sheet) then.Divide example to describe in detail below in conjunction with accompanying drawing.

Fig. 1 is the structural representation made from assembly method of the present utility model.

Fig. 2 is an A-A profile of the present utility model shown in Figure 1.

Fig. 3 is with moulding the structural representation of the present utility model that casting method is made.

Fig. 4 is a B-B profile of the present utility model shown in Figure 3.

Embodiment one (assembling method manufacturing):

With reference to Fig. 1, Fig. 2, on the sheet pedestal of making of insulating material (1), the center, two sides has the sphere pit (2) of symmetry respectively, and there are concave station (3) and rectangular pit (4) in sphere pit (2) both sides, on the pedestal (1) and a crescent hole (6) arranged.Lay a semiconductor diode (7) in the crescent hole (6).The two ends lead-in wire of diode (7) passes two through holes (8) respectively and enters in the rectangular pit (4), and welds mutually with the contact electrode (5) that is distributed in pedestal (1) two sides respectively, and forms bump (14).Welding back filling insulating properties concave station (3) and rectangular pit (4) in is sealed and is coated with material, as: resin, cured, sealing wax etc.

Embodiment two (with moulding the casting manufacturing):

With reference to Fig. 3, Fig. 4, in the sheet pedestal (1) of castability megohmite insulant (as: plastics) casting, the two ends lead-in wire of semiconductor diode (7) is welded on respectively on two contact electrodes (5) by bump (14), outside the concave spherical surface of contact electrode (5) was exposed to, two contact electrodes (5) were cast the center, two sides at pedestal (1) respectively.

When using the utility model,, the utility model need only be put in the lamp socket mouth, be screwed on screw-socket bulb and get final product if the lamp socket mouth of light fixture up; If down, need only heading into the utility model gently to screw in the lamp socket with screw-socket bulb, lamp socket gets final product.

Pedestal of the present utility model (1) can be made of any insulating material, generally can use various plastics; Contact electrode (5) can be made of any metal, is more satisfactory with phosphorus bronze sheet; Semiconductor diode (7) is the available silicon material both, also available germanium material, and its specification, parameter are decided on rated voltage, the power of the incandescent lamp bulb of adapted, be 0.1A～3A at operating current generally, and reverse breakdown voltage is that stepping is selected between 50V～600V.

Use the utility model, can make the life-span of common screw type incandescent lamp bulb prolong more than 40 times; Obtaining under the luminous flux condition that equates, the power consumption power that can save is: 1. obtain the identical intensity of illumination of common 40W incandescent lamp, only need to consume 30W power, save 10W; 2. obtain the intensity of illumination of common 25W incandescent lamp, only need to consume the 18W electrical power, save 7W; 3. obtain the intensity of illumination of common 15W incandescent lamp, only need to consume the 12W electrical power, save 3W.

Use defective of the present utility model to be: the intensity of illumination that obtain does not conform to the incandescent lamp bulb nominal power of adapted.For example will obtain the intensity of illumination of 40W ordinary incandescent lamp, must the adapted nominal power be the incandescent lamp bulb of 100W.
