Embodiment Construction

[0022] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0023] Such as image 3 As shown, a halogen lamp driving circuit of an infrared polarized light therapy instrument is composed of an AC-DC voltage stabilizing module, a DC-DC voltage stabilizing module, a reference voltage circuit, a sampling circuit, a comparing circuit, and an integrating circuit. The AC-DC voltage regulator module converts the 220V 50Hz AC power signal into 24V DC power. The DC-DC voltage regulator module converts 24V DC power into a 150W high-power 0-15V programmable voltage source for driving halogen lamps. The reference voltage circuit includes a D / A conversion circuit to generate a reference signal for controlling the output voltage. The sampling circuit obtains the voltage of the output signal of the halogen lamp driving circuit. The integral circuit is composed of operational amplifiers, capacitors, power supply and ...

Abstract

The invention belonging to the field of the instrument design discloses a halogen lamp driving circuit of an infrared polarization therapeutic apparatus. The driving circuit is composed of an AC-DC voltage stabilization module, a DC-DC voltage stabilization module, a reference voltage circuit, a sampling circuit, a comparison circuit, and an integral circuit. According to the driving circuit, theintegral circuit is formed by cascaded connection of two-stage integral units, so that the locking speed of an amplitude stabilization loop is increased. With introduction of one group of negative power supplies, the amplitude stabilization loop of the driving circuit is easy to lock, so that the output voltage range of the driving circuit is extended substantially and the driving power of the high-power halogen lamp is enhanced; and the output voltage range is 0 to 15V and the 150-W halogen lamp can be driven with full power. The infrared polarization therapeutic apparatus designed by using the halogen lamp driving circuit is superior to the same kind of foreign instruments in terms of core indexes like the output optical power and polarization degree at a leading level.

Description

technical field [0001] The invention belongs to the field of instrument design, and in particular relates to a halogen lamp driving circuit of an infrared polarized light therapy instrument.
