The alternating current energy-saving LED illuminating lamp has extremely fine energy-saving effect, and is extremely low in heating quantity.
Description
Technical field
The utility model relates to a kind of LED illuminating lamp, particularly utilizes the LED illuminating lamp of alternating current as power supply.
Background technology
Present most of light emitting diode LED lighting lamp is to use the direct current behind over commutation to supply with the LED lamp as power supply, though saved the part electric energy, can't give full play to the energy-saving efficiency of LED illuminating lamp.Find by retrieval, the relevant alternating current that utilizes of part is arranged directly as the LED illuminating lamp patent of power supply, find they or circuit more complicated by analysis, the components and parts that need are many, illuminating effect that reaches and power consumption ratio are higher, the heat that produces is also bigger, produce the problem that need install radiator additional thus, as application (patent) number " directly inserting the LED illuminating lamp of 220V AC network " patent for " CN200720192312.2 ", by fixed heat sink on case, the end face of radiator reaches cooling-down effect by the technical scheme that insulated substrate is bonded with electronic circuit board.
Summary of the invention
The utility model provides a kind of LED illuminating lamp of energy-conserving and environment-protective, illuminating effect and the power consumption ratio is higher, caloric value is bigger technical problem when solving the LED illuminating lamp and using alternating current as power supply.
The utility model is a kind of alternating current energy-saving LED illumination lamp, comprise transparent lampshade, lamppost, described led circuit plate is fixed on the lamppost, lamppost one end is provided with screw thread mouth or the bayonet socket that is complementary with socket, led circuit plate light-emitting area is towards Transparent lamp shade, the power connection points at its back side is wired to AC network by lamppost, described led circuit plate comprises by capacitor C 1, resistance R 1 constitutes holds up circuit and current-limiting resistance R2, be in series with light-emitting diode (LED) module described holding up between circuit and the current-limiting resistance R2, described light-emitting diode (LED) module is made of the two groups of LED strings and the inductance L of reverse parallel connection, inductance L is connected with the positive pole of LED string, and the light emitting diode number of described single group LED string is 12.
The utility model is according to the brightness needs, the led circuit plate of 2,3,4,5,6 or polylith can be together in parallel, and reaches bright more effect.
Because the utility model adopts two LED strings of reverse parallel connection, make the conducting and luminous in turn of LED string through the positive and negative half-wave of alternating-current power supply after the step-down, the electric energy of the consumption of therefore loosing than the power of the diffusing consumption of direct current less half, have good energy-saving effect, and caloric value is also very little.
Description of drawings
Fig. 1 is a led circuit plate line map of the present utility model;
Fig. 2 is the line map of two blocks of led circuit plates of the present utility model parallel connection.
The specific embodiment
As shown in Figure 1, the led circuit plate is made of two groups of LED strings that hold up circuit, reverse parallel connection, current-limiting resistance R2 series connection, the circuit that holds up wherein is made of capacitor C 1, resistance R 1, two groups of LED strings of reverse parallel connection are made of 12 LED and 1 inductance L, inductance L and LED string positive pole be connected, after connecting with alternating current, alternating current is through holding up the circuit step-down, earlier by inductance L, conducting LED string is luminous then through the positive and negative half-wave of the alternating-current power supply after the step-down.
As shown in Figure 2, as another embodiment of the present utility model, in order to increase the brightness of LED illuminating lamp, in time, be together in parallel 2 blocks of led circuit plates, reaches bright more effect, and as a same reason, increasing more led circuit plate will be brighter.
Through test, the utility model power of 1 led circuit plate is about 1W, and the utility model power of 2 led circuit plates is about 2W, and brightness is equivalent to the 40W incandescent lamp, has saved electric energy greatly.
