Description
Technical Field
The invention relates to a halogen lamp high-voltage excitation device, a halogen lamp device and an illumination environment box.
Background
The halogen lamp is a light source which generates arc discharge by utilizing transition between different energy levels of halogen gas atoms to emit light, and the metal halogen lamp is a high-intensity gas discharge lamp and belongs to the category of metal halide lamps. Has stronger line spectral radiation in the wavelength range of 350nm to 450nm, and the main peak value of the line spectral radiation is the resonance radiation spectral line of gallium with the wavelength of 403nm and 417 nm. In the field of environmental reliability testing, the material change and the color light decay degree of a simulation material after long-time day illumination are accelerated by using illumination conditions of high power, full spectrum and high irradiation intensity.
In the prior art, there are 2 types of common halogen lamp ignition devices (triggers): oscillator triggers and electronic triggers. The oscillator trigger is shown in the attached figure 1, and the working process is as follows: when the button K is pressed, the primary coil of the T1 is electrified and magnetized, so that the Z contact of the vibrator is disconnected, and after the coil is demagnetized, the Z contact is closed, and the steps are repeated. By switching Z on and off, the energy of the primary winding of T1 is transferred to the secondary winding, generating several kv of high voltage to charge C2. When the voltage reaches the breakdown point of the high-voltage arrester G, the electric energy on the C2 is discharged through the G and the T2 primary coil, and then a high voltage of ten thousand volts is generated on the T2 secondary coil to complete high-voltage excitation. The working principle of the electronic trigger is similar to that of the oscillator trigger, the electronic trigger adopts a secondary boosting mode, pulse current is adopted to charge a charging capacitor, and the difference is that the oscillator contact structure is modulated by pulses, and the substituted part is shown in figure 2.
Although the two types of common halogen lamp triggers are widely applied, the two types of common halogen lamp triggers have inevitable defects. The contact of the oscillator trigger high-voltage discharger can form an oxide film for a long time, so that the triggering reliability is influenced; the service life of the mechanical structure of the vibrator can influence the service life of the whole lamp system; mechanical shock when the vibrator is in contact easily causes repeated triggering, which affects the service life of the lamp. The electronic trigger avoids a plurality of defects of a vibrator trigger, is widely accepted in use, but still has partial defects when being used as an illumination environment box of automation equipment, such as easy formation of high-frequency radiation and interference on a microcontroller of a system; electronic circuits are extremely susceptible to damage from triggered energy recharge; the control is relatively complex, and the system reliability is reduced.

Detailed Description
The invention is further described below with reference to the accompanying drawings.
The invention relates to a high-voltage excitation device of a halogen lamp, which is applied to a halogen lamp device applied to a lighting environment box.
In detail, the high-voltage excitation device of the halogen lamp comprises an illumination loop 1, a low-voltage AC working source Us and a high-voltage AC power supply circuit, wherein the AC low-voltage AC working source Us is used for providing working voltage for the halogen lamp K; and the boosting circuit 2 boosts the input alternating current low-voltage working source Us into a high-voltage excitation source Ut when the time switch Kc is switched on.
Two auto-amplifiers L are connected in series in the lighting circuit 1 and are respectively arranged on two sides of the halogen lamp K, and an alternating current low-voltage working source Us, the primary of one auto-amplifier L, the halogen lamp K and the primary of the other auto-amplifier L form the lighting circuit 1.
The booster circuit 2 comprises a booster transformer T, an alternating current low-voltage working source Us, a timing switch Kc and a primary side of the booster transformer T are connected in series to form a circuit, and the alternating current low-voltage working source Us, a secondary side of one auto-coupling amplifier L, a secondary side of the booster transformer T, a vacuum discharge tube G and a secondary side of the other auto-coupling amplifier L are connected in series to form a circuit.
In this embodiment, as shown in fig. 3, three connection terminals connectable to the ac low voltage operating source Us are A, B, C respectively, and the switch Kc is located on the terminal a, when the timer switch Kc is closed, a loop formed by connecting the ac low voltage operating source Us, the timer switch Kc and a primary side of the step-up transformer T in series is conducted, a primary side voltage Uc of the step-up transformer T is equal to the ac low voltage operating source Us, a high voltage formed by the ac low voltage operating source Us and the high voltage excitation source Ut in the loop of the vacuum discharge tube G is enough to conduct two-stage discharge of the vacuum discharge tube G by the step-up of the step-up transformer T, so that the sum of the voltages of the high voltage excitation source Ut and the ac low voltage operating source Us after being connected in series is applied to secondary sides of the two auto-coupled amplifiers L, and the voltage is amplified by the two auto-coupled amplifiers L to obtain a secondary step-up voltage Uk at the primary side thereof, the voltage is applied to two stages of the halogen lamp K, and the halogen gas atoms inside the halogen lamp K with the voltage Uk at two ends jump to generate arc discharge to finish the lighting of the halogen lamp K.
At this time, as shown in fig. 4, when the time switch Kc is just closed, the current of the coupling amplifier L is small, the saturation inductance of the coupling amplifier L is not large, and the back-flow current is suppressed, so that the safety of the power supply is ensured. However, as the transition density of the halogen atoms in the halogen lamp K rapidly increases, the internal impedance of the halogen lamp K rapidly decreases from the high-impedance state before excitation, and at this time, the current provided by the ac low-voltage operating source Us also rapidly increases enough to normally maintain the halogen lamp K at the point, at this time, the time switch Kc is opened, the whole process is about 2s, and the on/off of the time switch Kc can be controlled by a software program. At this time, the booster circuit 2 is not conducted, the alternating current low-voltage working source Us supplies power normally, the lighting circuit 1 supplies working voltage to the halogen lamp K only by the input alternating current low-voltage working source Us, the current of the self-coupling amplifier L is correspondingly increased along with the increase of the output current of the alternating current low-voltage working source Us, the self-coupling amplifier L starts to gradually saturate, the inductance value is exponentially reduced, and finally a smaller inductance value is achieved, so that the lighting circuit 1 is normally conducted, and the alternating current low-voltage working source Us stably supplies power to the halogen lamp K according to power.
The self-coupling amplifier L adopts a novel soft magnetic iron core, the characteristics that the inductance tends to be saturated when the self-coupling amplifier L is in low current and the inductance tends to be saturated when the self-coupling amplifier L is in high current and the inductance is greatly reduced are fully utilized, the self-coupling amplifier L is excited and lighted at high voltage in the closed lighting process of the time switch Kc, the self-coupling amplifier L prevents energy from being recharged to damage a power supply when being excited and reduces electromagnetic interference generated by di/dt; in addition, after the time switch Kc is switched off and the high-voltage excitation lighting is finished, the inductance is greatly reduced due to the saturation of the inductance of the self-coupling amplifier L, so that the alternating-current low-voltage working source Us has smaller voltage drop, and the system efficiency is improved.
In this embodiment, as shown in fig. 3, two ends of the ac low-voltage operating source Us are connected to a first filter capacitor C1, and a protection capacitor C3 is connected in parallel to the first filter capacitor C1 for preventing the C1 from being damaged; the primary side of the step-up transformer T is connected in parallel with a second filter capacitor C2 for filtering the ac voltage.
