Description

The New LED electricity-saving lamp

Technical field

The utility model relates to a kind of LED illuminating lamp.

Background technology

Adopt LED as illuminating lamp owing to compare and common process lamp in vain and fluorescent lamp is wanted a lot of favors that obtained a lot of users of power saving, 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, but light is owing to stable more dazzling inadequately, number of patent application be 200910039068.X's " a kind of LED electricity-saving lamp " a kind of LED electricity-saving lamp is disclosed, it comprises lamp holder and cooling base, this cooling base is installed in an end of lamp holder, one end of LED luminescent panel is connected with cooling base, the LED driving constant-current power is built in the diffuser and electrically connects with lamp holder and LED luminescent panel respectively, owing to adopt LED luminescent panel and efficient diffuser to cooperate, the soft diffusion of the light that LED is sent, part has solved the luminous dazzling and caloric value of LED point and has caused the difficult problem of dispelling the heat greatly, but because the continuous conversion sense of current of alternating current that LED uses, be only and cause the unsettled reason of LED light, also be to cause luminous dazzling one of the main reasons, present LED is energy-conservation well not to be addressed this problem, and the structure more complicated.

Summary of the invention

The utility model provides a kind of New LED electricity-saving lamp that can effectively solve luminous instability problem.

The utility model New LED electricity-saving lamp comprises lampshade, power interface and led circuit plate, the led circuit plate is connected by power interface and external communication electricity, described led circuit plate comprises light emitting diode matrix, rectifier bridge, filter and the reduction voltage circuit that is made of capacitor C 1, resistance R 1 parallel connection, filter comprises filter capacitor C2 and filter inductance L, power supply is switched to light emitting diode matrix after by reduction voltage circuit, rectifier bridge, filter, described light emitting diode matrix adopts 4 tunnel parallel waies, 12 LED of every road series connection.

The utility model adopts step-down---rectification---filtering mode steady voltage, make that the LED behind the rectifying and wave-filtering is luminous stable, and by reducing capacitor C 1 capacity of reduction voltage circuit, reduce the rectifier bridge electric current, thereby reduce the quantity of LED lamp, reduced caloric value, therefore not only luminous stablizing do not glimmered, and has good energy-saving effect yet.
