Description
Technical field
The utility model is related to technical field of lighting fixtures, and specially a kind of low frequency dodges LED illumination structure.
Background technology
Stroboscopic (flicker) is the phenomenon that the intensity of light source has light and shade to change over time, and light source stroboscopic phenomenon just refers to light
The light that source is sent is with the time in change that is quick, repeating so that light source is beated and unstable, that is, the fluctuation of electric light source luminous flux
Depth.Luminous flux fluctuation depth is bigger, and stroboscopic is more serious.Different degrees of influence is also had to human body.General electric current is
It is 50/60Hz exchange electricity transmission by frequency, the supply voltage of light fixture is in switch periods in ripple in the form of sine wave
Peak to fluctuating back and forth between trough.Thus, it is possible to create the stroboscopic of 2 times of frequency of supplies, that is, 100/120Hz.If not yet
There are suitable electronic circuit, such as ballast, driving or power supply, light source will produce stroboscopic.About 3 to 70Hz low frequency dodges can
It can cause the reactions such as the headache, dim eyesight, confused and worried or initiation epilepsy of high quick crowd.Between about 100 between 500Hz
Moderate stroboscopic may result in the indirect consciousness (as caused by the persistence of vision) of stroboscopic effect, in this case, dynamically
Object may show as a series of static images.It is dangerous for industrial site.LED lamp is that dc source is supplied
Electricity, the light that its light source is sent also will be DC form (small fluctuation or pulsation is superimposed with the basis of direct current), from thing
Said in the angle of reason, the degree of fluctuation for the light source luminescent that its luminous fluctuation works well below alternating current really.But,
What it inputted power supply is still form of communication, AC ripple is very difficult to avoid completely by LED/light source, so LED lamp
Also there can be stroboscopic.
For control device, ripple current is an important arch-criminal for producing stroboscopic.Ripple current is rectification
With the alternating component still existed after filtering.Ripple current is superimposed upon on direct current, with different frequency and curve.This is exchanged into
Dividing fluctuates the power of LED modules, brightness can be made to change again in turn.The quantity and frequency for being superimposed exchange are to produce
The deciding factor of stroboscopic.There is the very fast response time additionally, due to LED, therefore under certain conditions, LED stroboscopic
Characteristic is determined mainly due to the characteristic of driving power supply.Therefore LED/light source stroboscopic problem more to be protruded than traditional light source,
Seriously, it is necessary to give necessary concern.The requirement that no stroboscopic is met for current LED power is simple is also to accomplish.Substantially
There are this three kinds of modes：1st, output electrochemical capacitor is increased.This scheme theoretically can absorb part using electrochemical capacitor and exchange
Ripple, but practical experience is taught that：After ripple control within limits (10%), it is difficult to further drop
It is low, unless electrochemical capacitor is disregarded into adding for cost, can not fundamentally it be completely eliminated.2nd, using the passive PFC side of valley fill type
Case.This scheme is also a kind of processing mode of most main flow.Power factor (PF) is carried out using two big electric capacity and three diodes
Correction, because there is big electrochemical capacitor behind rectifier bridge, AC ripple is absorbed, by inductance or transformer to secondary
The electric current of level part is direct current.Valley fill type scheme is there is also some problems, and output voltage is in more than 40V, it is impossible to make 90-
265V full voltages are inputted, and valley fill circuit output voltage valley only has the half of electrolysis filter circuit valley, the rectification square of valley fill type
Output voltage is low more many than the output voltage after common rectification after formula rectification, it is possible to be what low pressure was inputted after use valley fill type
Band carries not enough.Furthermore, no matter isolated or non-isolated valley fill type scheme, stress_responsive genes can not pass through at all, power factor (PF)
More than 0.95 can not be fully achieved.3rd, using two-level scheme.On the basis of insulating power supply, then add one-level DC to DC, just
The influence of AC ripple can be eliminated.Valuation Standard can be also fully achieved in electrical parameter.But this scheme has certain increasing in cost
Plus, it is necessary to add a power management chip and part peripheral circuit, these three methods have certain defect, it is impossible to effectively
Solution low frequency the problem of glisten, while these three, which are violated the law, implements relatively difficult, be not suitable for promoting the use of.
Utility model content

Integral structure.
Compared with prior art, the beneficial effects of the utility model are：This is arranged on the sky between Transparent lamp shade and lamp plate
Interior to be provided with rare earth inorganic material, fluorescent material and silica gel, these material absorbable energy of light source have light and shade change in light source
When unaffected continuous illumination reach the thermal inertia of simulation incandescent lamp and the afterglow effect of gas-discharge lamp, i.e. conventional light source
Response speed is slow (rising, fall time length), and lighting has the very property delayed, therefore greatly insensitive to the shake of electric current, even if line
Ripple electric current causes also do not occur stroboscopic change during light source fluctuation because of LED quick response, effectively solves illuminating lamp low frequency
The problem of flash of light, and this product solves this problem by the way of physics, will not occur what is triggered because changing lamp body structure
Various problems, while the present apparatus sets fluted and projection on the top of lamp housing, can be effectively the circuit board inside device
Radiating, it is ensured that the safe handling of product, the present apparatus is reasonable in design, simple in construction, need not change lamp body structure or increase by zero
The problem of low frequency glistens is solved under conditions of part, green non-pollution is adapted to promote the use of.
