The utility model is through illumination photometry system and power measuring system; Can demonstrate the illumination and the power of desk lamp; Make people when using desk lamp, can in time understand the problem of the brightness value on the desk lamp power consumption and the desk lamp irradiation scope of operation; So that the brightness of desk lamp is transferred to both energy-conservation, the illumination position of suitable human eye again.
Description of drawings
Fig. 1 is the desk lamp circuit structure diagram that can show illumination and power according to the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further to describe in detail.
Desk lamp as shown in Figure 1, that the utility model provides can show desk lamp illumination and power, and it comprises:
Light source: be used to emit beam and illuminate the irradiated scope of operation;
Power supply: be used to light source and permanent Optimizing Control System power supply with an automatic light meter;
Permanent Optimizing Control System with an automatic light meter: be used to regulate the power and the brightness of light source, and link to each other with power cathode through resistance R 2, triode VT transmitting terminal, resistance R 3 successively;
Photoelectric sensor (RL): be used for the brightness of inductive desk lamp irradiation scope of operation glazing, and convert light signal to the illumination photometry system can the measured voltage signal;
Illumination photometry system: be used for the magnitude of voltage at measuring light electric transducer VL place,, calculate brightness value on the desk lamp irradiation scope of operation and deliver on the display floater and show according to different VL magnitudes of voltage;
Power measuring system: be used for the magnitude of voltage at measuring resistance R3 end VP place, according to different VP magnitudes of voltage, the performance number that calculates desk lamp is delivered on the display floater and is shown;
Display floater: the illumination and the power that are used to show desk lamp.
Display floater can be a charactron, also can be liquid crystal panel, and preferred display floater is positioned on the Desk lamp feet.
Photoelectric sensor can be photo resistance, photodiode, phototriode, photoelectric tube or photomultiplier.It is positioned at the catoptrical position that can sense on the desk lamp irradiation scope of operation, is preferably placed on the Desk lamp feet.
When illumination change, the magnitude of voltage of photoelectric sensor (RL) end VL can change the VL magnitude of voltage that different brightness values is corresponding different.When photoelectric sensor is photo resistance, according to the light characteristics of photo resistance: VL=V * RL ÷ (RL+R1)=5RL ÷ (RL+R1).When illumination high=＞RL is low=＞VL is low; When illumination low=＞RL is high=＞VL is high, promptly the illumination of light is different, its VL value is difference also.So, desk lamp illumination and power display system show brightness value according to different VL magnitudes of voltage through calculating the back on display floater.The electric current of desk lamp is through resistance R 2, through triode VT, then through the resistance R 3 last negative poles that flow into power supply; The desk lamp different brightness; Its power consumption (W=V * I) also different; And power consumption is not simultaneously, and when voltage fixedly the time (the general voltage of all electrical equipment is fixed), its electric current (I=W ÷ V) is also different.Voltage (the V at VP place
P=R * I, R fixes) also different, desk lamp illumination and power display system then show performance number according to different VP magnitudes of voltage through calculating on display floater.
The foregoing description is used for the utility model of explaining; Rather than the utility model limited; In the protection range of the spirit of the utility model and claim,, all fall into the protection range of the utility model to any modification and the change that the utility model is made.
