The specific embodiment
With reference to figure 1, incandescent lamp 10 in the LED fluorescent lamp 100 of the prior art is connected in series with controllable silicon dimmer 12, waveform by controllable silicon dimmer 12 control alternating currents, because must connect with load, so this method can only be controlled a load, and there is the high-tension electricity of 220VAC at the light-control knob place of the controllable silicon dimmer 12 that can touch at staff, causes the danger of electric shock.And in circuit, produce easily and disturb.
With reference to figure 2, adopted AC/DC Switching Power Supply 22 to drive according to the LED light fixture 20 in a kind of hand of the present utility model LED fluorescent lamp 200 with an automatic light meter, but between AC/DC Switching Power Supply 22 and LED light fixture 20, be coupled into a DC/DC tunable optical constant-current driving power supply 26, potentiometer 24 is by control handle 25 control pulsewidth modulation (PWM, Pulse Width Modulation) signal generator 28 produces pulsewidth modulation (PWM, Pulse Width Modulation) signal controlling DC/DC constant-current driving power supply 26 is with driving LED light fixture 20.
With reference to figure 3, also comprise LED light fixture 30 and AC/DC Switching Power Supply 32 according to the manual dimming LED fluorescent lamp 300 of another kind of the present utility model, also comprise in addition: DC/DC tunable optical constant-current driving power supply 36, connect described AC/DC Switching Power Supply 32 and LED light fixture 30, be used for driving LED light fixture 30; Pwm signal generator 38 connects described DC/DC tunable optical constant-current driving power supply 36, is used to produce pwm signal and it is inputed to DC/DC tunable optical constant-current driving power supply 36; And potentiometer 34, connect described pwm signal generator 38, be used for by a control handle 35 control pwm signal generators 38.Different is, the output of pwm signal generator 38 also can connect power driving circuit 39 in the present embodiment, the other end of this power driving circuit 39 connects described DC/DC constant-current driving power supply 36, can make at least two above LED light fixtures 30 of described pwm signal generator 38 controls like this, comprise the light fixture among the individual lamp unit kn of first lamp unit k1 and n (n 〉=2).
Prior art all adopted can not light modulation non-isolation and isolated constant-current driving power supply, thereby can't light modulation.The technical program has then adopted the tunable optical constant-current driving power supply of independent research, has solved the possibility problem of light modulation.Specifically, common LED sight lamp adopts non-isolation or separate AC/DC power supply, be difficult to the light modulation of realization, and the utility model has adopted the regular tap constant voltage source to add tunable optical DC/DC constant-current supply, just can be easy to realize impulse width modulation and light adjusting to LED.The utility model has adopted the pwm signal generator of low pressure to produce dim signal simultaneously, its power supply is from the AC/DC Switching Power Supply, just can change its pulsewidth with potentiometer, thereby reach the purpose that changes brightness, just do not have the 220V high pressure at the adjusting knob place like this, and have only the safe DC voltage below the 36V.The output of low pressure PWM generator adds power drive, thereby has improved its driving force, can control a lot of fluorescent lamps simultaneously by a control handle.
In current energy shortage, atmosphere warms under the situation, and further energy-conservation is the task of top priority.China's electric consumption on lighting amount accounts for 20% of total electricity consumption, and wherein indoor electric weight accounts for 10%, and fluorescent lamp account for wherein 70% to 80%, the fluorescent lamp of South China is nearly 5,000,000,000 according to statistics, hundred million of the nearly 50-100 in East China.If all adopt the LED fluorescent lamp, can economize on electricity 50%, in Beijing, suitable economize on electricity 2,000,000,000 degree in these big cities, Shanghai, and common fluorescent lamp can't be realized any light modulation at all, if adopt manual light modulation, then can economize on electricity more than 10% again, be equivalent to 200,000,000 degree electricity, its economic effect is very surprising.
Should be noted that in addition; the above only is a preferred implementation of the present utility model; and go for various LED light fixtures and be not limited to the LED fluorescent lamp; for those skilled in the art; under the prerequisite that does not break away from the utility model design; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
