Detailed description of the invention
Fig. 1 is the schematic appearance of the photoconductive resistance switch desk lamp that this utility model embodiment provides.In this example, photoconductive resistance switch desk lamp includes lamp body 1 as we can see from the figure, the lamp socket 2 being connected with described lamp body 1 and playing a supporting role described lamp body；Described lamp body 1 is provided with the luminous body (not shown) that can convert electrical energy into luminous energy, and described lamp socket 2 is provided with and opens and closes automatically according to room brilliancy and in room brilliancy less than the noctilucence body 3 of continuous illumination when setting threshold value.Night, noctilucence body 3 was lighted automatically, daytime noctilucence body self-extinguish.Additionally, the brightness of the light that noctilucence body sends will not decay during night, it is possible to ensure luminous whole night.
Fig. 2 is the circuit diagram of the photoconductive resistance switch desk lamp noctilucence body that this utility model embodiment provides.Can be seen that described noctilucence body includes the IGCT that LED, input are connected with described LED outfan；The diode being in parallel with described LED and described IGCT, the resistance being in parallel with described diode, described resistance is in parallel with described LED and described IGCT；And, the photoresistor being in series with the outfan of described IGCT, described photoresistor is in series with described diode；Described photoresistor is in series with described resistance.
When light is bright, photoresistor RL resistance is little, and the 220V alternating voltage unidirectional pulse DC voltage after VD rectification voltage after R and RL dividing potential drop is little, the voltage being added to IGCT VT control pole is little, at this moment IGCT Vt can not turn on, so lamp LED loop no current, lamp does not works.When dark, photoresistor RL resistance is big, and the voltage after R and RL dividing potential drop is big, is added to IGCT VT and controls the voltage of pole greatly, and at this moment IGCT VT enters conducting state, so lamp LED loop has electric current to flow through, lamp is lighted.
The photoconductive resistance switch desk lamp that this programme provides can help the people of people's especially myopia to it can be clearly seen that the shift knob position of desk lamp in night, can open switch the most accurately.Additionally, the least and due to photoconductive resistance the effect LED on daytime of LED power consumption that this programme uses will not be bright, electricity will not be wasted.It is possible to solve inadequate problem of existing Luminous desk lamp lighting time well.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all any amendment, equivalent and improvement etc. made within spirit of the present utility model and principle, within should be included in protection domain of the present utility model.
