Description
Technical field
It is the high performance lED illuminating lamp of power supply with the alternating current that the utility model relates to a kind of, belongs to lighting technical field.
Background technology
The LED illuminating lamp belongs to cold light source, have luminous efficiency height (can economize on electricity 80%), long service life (can reach 50,000 to 100,000 hours), (dazzle is little in environmental protection, radiationless, do not contain mercury element in the lamp, do not produce harmful substance in the use), photochromic soft, advantage such as illuminance is even and irradiated area is big.Along with the breakthrough and the appearance blue, green, white light LED of third generation semi-conducting material gallium nitride, the semiconductor lighting instrument is expected to substitute the leading position of conventional incandescent, fluorescent lamp, Halogen lamp LED, becomes the main product of illuminating industry.At present, the LED illuminating lamp also is in the starting stage, and generally all uses dc source to power, and uses inconvenience, if make road lamp power supply with solar energy the high disadvantage of manufacturing cost is arranged again; The great power LED light emitting diode requires again comparatively harsh to problems such as installation, heat radiations, these factors are very limited applying of LED illuminating lamp.
Summary of the invention
The utility model be used to overcome prior art defective, provide a kind of rational in infrastructure, the alternating current large-power LED illuminating lamp that is suitable for applying.
The alleged problem of the utility model realizes with following technical proposals:
A kind of alternating current large-power LED illuminating lamp, constitute by the AC-DC power converting circuit, led drive circuit and the LED light emitting diode that connect successively, described LED light emitting diode is welded on the aluminium base printed substrate 2, coating heat-conducting silicone grease layer between LED light emitting diode and the aluminium base printed substrate 2.
Above-mentioned alternating current large-power LED illuminating lamp, described led drive circuit is made up of constant flow module IC, inductance L and feedback resistance Rf, constant flow module IC adopts LM3402, the VIN of described constant flow module IC, GND end is connected to the direct current output positive and negative electrode of AC-DC power converting circuit respectively, its SW end connects power cathode through stabilizing inducatnce L, LED light emitting diode, feedback resistance Rf successively, and the feedback signal on the feedback resistance Rf connects the CS end of constant flow module IC.
Above-mentioned alternating current large-power LED illuminating lamp is set up fin 1, and affiliated fin 1 is fixed in the back side of aluminium base printed substrate 2, applies the heat-conducting silicone grease layer between the two.
Above-mentioned alternating current large-power LED illuminating lamp, described LED light emitting diode are provided with many groups, every group of 1-6 the LED light emitting diode that be connected in series, and the group number of LED light emitting diode is corresponding with the number of led drive circuit.
The utility model utilizes the AC-DC power converting circuit to convert alternating current to direct current, is powered to the LED light emitting diode with constant electric current by constant flow module IC again, can guarantee that LED brightness is longer all even service life.The LED diode is welded on the aluminium base printed substrate, and aluminium base printed substrate is connected with the electronic radiation device by heat-conducting silicone grease, is limited to below 55 ℃ as temperature to guarantee the LED plumber.The utility model has not only been realized having reduced power supply cost with the power supply of alternating current as the LED illuminating lamp, and rational in infrastructure, dependable performance, easy to assembly, long service life.
