Brightness is equivalent to common 40W fluorescent lamps.It also has the characteristics of high temperature resistance, moistureproof and waterproof, anticreep and small volume.Can conveniently it apply
In the desk lamp with dimmer switch design of showcase.
Wherein, the number for adjusting control button 6 is two, be button button, one for adjusting the colour temperature of white light,
The one flash of light rhythm for being used for adjusting flash lamp 5.
With reference to Fig. 2 to Fig. 4, the explanation of principle is operated：
Colour temperature adjustment is carried out by adjusting control button 6, is specially：Long-press is motionless, the colour temperature of light fixture can slowly from
2800K-6500K-2800K circulation, the colour temperature section release button wanted to you just, colour temperature change when total light source power and
Luminous flux is constant.
Button is adjusted by the rhythm that glistens and carries out rhythm adjustment of glistening, is specially：Long-press is motionless, middle colored light sources meeting
Color-is slowly changed gradually to slow flash-gradually to quick flashing by slow flash closed-color cycle is changed, the effect release button wanted to you is just
Row.Light fixture has memory capability, the state that start can be reappeared before shutdown every time.
Control chip uses single-chip microcomputer in the utility model, therefore the pulse of PWM dimming driving circuits is from the PWM of single-chip microcomputer
Pin output obtains, the PWM pin output low level of single-chip microcomputer, when effective adjustment action and key press time occur for adjustment control button 6
Less than 0.5S, it is high level (i.e. most bright state) that PWM pin, which are overturn, if key press time is more than 0.5S, PWM pin will start output side
Ripple signal, and dutycycle from 1/255 to 254/255 gradually start increase (brightness of LED continuously increases to most by minimum
It is high), realize that stepless dimming, about 3S keep constant after can reach maximum brightness；If now unclamping hand long-press again, dutycycle is then
It is gradually reduced, minimum brightness is reduced to after about 3S and is remained unchanged, if when PWM is effectively exported, effective button occurs

Preferably, the material of lamp casing is aluminium alloy.
Aluminium alloy has very high plasticity, easy to process, can be made into various section bars, sheet material；The corrosion resistance of aluminium alloy
It is good；As the making material of lamp casing, the making demand of different shape lamp casing can be met.
Specifically, the surface of aluminium alloy is using the oxidation processes profile that sandblasts.
The oxidation processes that sandblast are to use compressed air as power, to form high velocity spray beam by material spray (copper ore, quartz
Sand, diamond dust, iron sand, SEMEN AMOMI LONGILIGULA) be ejected into need workpiece surface to be processed at a high speed, make the outer surface of workpiece surface appearance or
Shape changes, and due to impact and shear action of the abrasive material to workpiece surface, the surface of workpiece is obtained certain cleannes
With different roughness, make the mechanical performance of workpiece surface be improved, therefore improve the fatigue resistance of workpiece, add it
Adhesive force between coating, the durability of film is extended, be also beneficial to the levelling and decoration of coating.
Intelligent dimming lamp in the utility model is not limited to the desk lamp with dimmer switch for two shapes mentioned in above-mentioned two embodiment,
It can be modified according to the actual requirements, in the scope of protection of the utility model, and control chip is also not necessarily limited to be monolithic
Machine is a kind of.
Finally it should be noted that：Various embodiments above is only to illustrate the technical solution of the utility model, rather than it is limited
System；Although the utility model is described in detail with reference to foregoing embodiments, one of ordinary skill in the art should
Understand：It can still modify to the technical scheme described in foregoing embodiments, either to which part or whole
Technical characteristic carries out equivalent substitution；And these modifications or replacement, the essence of appropriate technical solution is departed from this practicality newly
The scope of each embodiment technical scheme of type, it all should cover among claim of the present utility model and the scope of specification.
