Abstract
The invention discloses a high-power LED lamp driving power supply. The high-power LED lamp driving power supply is composed of first to seventh resistors, first to seventh diodes, first to fourth capacitors, a voltage-stabilizing tube, a potentiometer, a transformer, a field-effect tube and bidirectional controlled silicon. Compared with the prior art, the discharge capacity of a mono-crystallized gate tube is gradually increased from low to high through a slide rheostat; the turn-on angle of a bidirectional thyristor is gradually increased from small to large through a delay trigger pulse; therefore, even the resistance value of the slide rheostat is adjusted to be minimum, the bidirectional thyristor cannot be fully conducted instantly; therefore, load current is limited; the purpose of softly starting is achieved; energy consumption is reduced; the service life of an LED lamp is prolonged; and thus, the high-power LED lamp driving power supply has popularization and use value.
Description
Technical field
The present invention relates to a kind of LED power, particularly relate to a kind of great power LED lamp driving power source.
Background technology
Visible ray can be given off when electronics and hole-recombination, thus can be used to make light emitting diode.?
As display lamp in circuit and instrument, or form word or numerical monitor.Gallium arsenide diode glows,
Gallium phosphide diode green light, silicon carbide diode Yellow light-emitting low temperature, gallium nitride diode blue light-emitting.Because of chemical
Matter divides again Organic Light Emitting Diode OLED and inorganic light-emitting diode LED.In prior art, for high-power
The power supply of LED directly drive, stronger power causes transient voltage too high, thus causes LED
Service life shortens, and power consumption is higher, accordingly, there exist room for improvement.
Summary of the invention
The purpose of the present invention is that provides a kind of high-powered LED lamp to drive electricity to solve the problems referred to above
Source.
The present invention is achieved through the following technical solutions above-mentioned purpose:
