Fig. 1 has described an embodiment of the present utility model.Comprise a screw socket (or bayonet socket or plug etc.) bulb shape shell, shell has glass or transparent plastic shell 1, hyaline test 1 is loaded on the metal-back 2, metal-back 2 is as an extraction electrode, 2 times bottoms of metal-back have an extraction electrode 3 in addition, LED 1, the LED2 (or alternating-current light emitting diode matrix), certain of two reverse parallel connections are housed in the shell, wherein also can have one to be general-purpose diode, another is light-emitting diode or direct current dot matrix LEDs.Also have a decompression capacitor C to be connected in the shell, as long as directly be loaded in the line and can use,, need only direct spiral shell when then using and to make it luminous during use at (on the circuit if any decompression device) on the required circuit if do not adorn electric capacity with light-emitting diode.

Fig. 2 has described and can be used as a kind of circuit structure that little power consumption exchanges illuminating lamp.It is to be in series by a LED, general-purpose diode D reverse parallel connection and with a decompression capacitor C, can be encapsulated in the shell, draws with two direct pins, and also available screw socket or bayonet socket miniature bulb form are drawn, and be nonpolarity.

Fig. 3 has described another kind of circuit structure.What it was different with precedent is, two diodes are light-emitting diode, LED 1, LED2 reverse parallel connection, because the positive and negative half cycle of available interchange is luminous, therefore, luminosity will be higher than example shown in Figure 2.

Fig. 4 is a kind of little power consumption illuminating lamp that uses on the electric main circuit that can directly be connected to, a shell is arranged, at least the LED 1 and the LED2 that comprise two reverse parallel connections in the shell, (certainly, LED also can adopt two groups of series connection light-emitting diodes reverse parallel connection again) and be connected to step-down transformer B between civil power and reverse parallel connection LED 1 and LED2, the reverse parallel connection LED 1 and the LED2 other end also join with civil power.It can utilize all-wave luminous.

By calculating as can be known, Fig. 2 describes the lighting pilot lamp circuit, and under the situation in 1 year of continuous use, also a power consumption is less than 100W.Really having realized little power consumption, though the brightness of lighting pilot lamp is low, has been enough for keyhole, switch enclosure etc. provides low-light illumination, and can not influence daily life such as sleep.If utilize illuminating lamp shown in Figure 3, although utilize all-wave luminous, power consumption increases to some extent, and brightness has increased by one times, and that power consumption is still is inappreciable, uses also can not increase how many burdens of user for a long time.

Fig. 5 has described another kind can directly be connected to the little power consumption illuminating lamp that uses on the civil power.Two LEDs 1, LED2 and the transformer B of series connection are housed in the shell, and its available half-wave is luminous.Certainly, also can adopt series connection more than two.

Fig. 6 has described another little power consumption lighting lamp circuit structure.It is made of the light-emitting diode of eight groups of (or other number groups) two or two reverse parallel connections, series connection mutually between each group, the power consumption of total power consumption≤several single alternating-current light emitting diode assemblies, still at the category of little power consumption, but brightness can significantly increase, the light-emitting diode group that is in series is connected on the 220V civil power (or 380V) together with decompression capacitor C (or other voltage drop elements) again, can constitute little power consumption surface electroluminescent lamp.

Fig. 7 has described the switch that little power consumption illuminating lamp is housed.On the switch module shell 71 of cordwood system type (or other versions), the former switch module piece 72 that is equipped with, 73 of little power consumption lighting pilot lamp building-blocks of the present utility model are loaded on the next door (or upper and lower etc. place) of switch module piece 72, an indicator light LED (can directly utilize the shell of LED) is arranged on the indicator light building-blocks 73, certainly, also can select the switch of other versions, as long as increase little power consumption lighting pilot lamp on the switch housing surface.Also can combine with other household electrical appliances such as refrigerator, electric fan, radio-cassette player or the like.

Fig. 8 has described the utility model circuit structure that adopts other connection.Have a capacitor C, capacitor C to be connected with a rectifier bridge ZD, one group of LED is connected with rectifier bridge ZD.Because the power consumption of rectifier bridge is also very little, so still do not lose little power consumption.

Fig. 9 has described and has adopted transformer to make little power consumption illuminating lamp of current limliting voltage drop element, a transformer B is arranged, transformer B is connected with rectifier bridge ZD, LED, equally also formed little power consumption lighting pilot lamp, because the loss of transformer B is less than 50% of light-emitting diode power consumption, so the power consumption of integrated circuit is still lower.Certainly, the volume of whole indicator light increases to some extent, and the example volume is not small and exquisite as previously described.

Figure 10 has described the circuit structure of the present utility model that can be made into the assembled unit piece, and (or other suitable number (as 20,24,32 etc.) light-emitting diode (also can comprise diode) constitutes, and goes here and there mutually with capacitor C rectifier bridge ZD after the series connection to form again by 16.

Crosstalk appearance C is synthetic again by two groups eight series connection light-emitting diode reverse parallel connections for Figure 11.

Cause burning of LED in order to solve the pulse high current discharge when the switch of electric capacity, transformer, can in the loop, be connected in series one 100 Ω left and right sides small resistor, can limit pulsed discharge intensity, even as adopt multi-stage LED series connection as more than 8 grades series connection do not add resistance and can prevent from effectively to burn yet, electric capacity reduces also can prevent to burn.

Figure 12 has described the little power consumption solid luminescence of a kind of alternating current 220V bulb: have a transparent organic glass shell (or other suitable material shells) 81, shell 81 to be contained on a bayonet socket (or screw socket) metal shell 82, there is leading foot 83 shell 82 lower ends, be equipped with in the shell 81 and exchange surface electroluminescent lamp 84 (light-emitting diode by two groups of reverse parallel connections is formed), 82 on shell 81 and shell have bakelite base 85 bases such as (or) ABS plastic.This example can directly be packed into and be used in the 220V civil power.
