The technical problem that the utility model proposed is to solve like this: construct a kind of LED lamp, it is characterized in that: comprise power supply rectification filter circuit, voltage stabilization constant current LED drive circuit and LED illuminance control circuit; Described power supply rectification filter circuit is connected and composed by insurance FT1, bridge rectifier D 1-D4, filtering voltage regulation capacitor C 1-C5, inductance L 1-L2, diode D5 and integrated voltage stabilizer U1; Described voltage stabilization constant current LED drive circuit detects control device U2, Zener diode D6 by triode T1, optocoupler and resistor R 1-R3 connects and composes; Described LED illuminance control circuit is connected and composed by illumination change-over switch SW1, the powerful illuminator LED1-LED7 of high brightness warm white and voltage-stabiliser tube D11-D17.
The beneficial effects of the utility model are: luminous efficiency height, light quality are good, adjustable brightness, energy-conservation electric energy, voltage adaptation wide ranges, long service life and steady performance, and the desk lamp that can do eyeshield uses.
Description of drawings
Accompanying drawing 1 is a circuit structure diagram of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, exchange the interior arbitrary voltage of 80V-270V scope through insurance RT1, bridge rectifier (D1-D4), capacitor (C2, C3, C4, C5), inductance (L1, L2) form the pi type filter output dc voltage, one the tunnel through R1 supply LED illuminator, one the tunnel through triode T1, resistance R 2, optical coupler U2, height integrated voltage stabilizer U1, take a sample, analyze, compare and control, the led drive circuit of forming pressure-stabilizing constant flow, D6 is the Zener diode of triode T1 base stage, D5 is a fast recovery diode, U1 is the height integrated package of pressure-stabilizing, (1) pin of optical coupler U2 links to each other with resistor R 2 one ends, (2) pin of optical coupler and the negative pole of output link to each other, (3) pin of optical coupler links to each other with (2) pin of height integrated package of pressure-stabilizing U1, and optical coupler (4) pin links to each other with rectifier (D1-D4) output ground.When being transported to LED illuminator A, the reduction of B both end voltage because of grid voltage change, the constant current sampling rate is managed the T1 base potential and is reduced, the ec electric current of T1 increases, increase by R2, optical coupler (1), (2) pin electric current, optical coupler (3), (4) electric current reduce, (3) pin above earth potential of height integrated package of pressure-stabilizing U1 descends, and A, B terminal voltage raise; When being transported to LED illuminator A, the rising of B both end voltage because of grid voltage change, the constant current sampling rate is managed the T1 base potential and is raise, the ec electric current of T1 reduces, reduce by R2, optical coupler (1), (2) pin electric current, optical coupler (3), (4) electric current reduce, (3) pin above earth potential of height integrated package of pressure-stabilizing U1 rises, and A, B terminal voltage reduce, and promptly remains LED illuminator A, the B both end voltage is constant.C1, C6, C8 are HF filtering capacitor among Fig. 1, and C7 is a voltage stabilizing low frequency filtering electric capacity; SW1 is the manual rotary change-over switch, LED1 and LED2 lighted when contact contacted 1 contact, LED1-LED3 lighted when contact contacted 2 contacts, LED1-LED4 lighted when contact contacted 3 contacts, LED1-LED5 lighted when contact contacted 4 contacts, LED1-LED6 lighted when contact contacted 5 contacts, and LED lighted entirely when contact contacted 6 contacts; D11-D17 be respectively with the Zener diode of LED parallel connection, the one, prevent that the single overtension of powered on moment LED illuminator from damaging the LED illuminator, the 2nd, when the LED of a plurality of series connection illuminator has a damage to open circuit, Zener diode in parallel on this illuminator punctures conducting, guarantees that the LED illuminator of other series connection is normally luminous.
The utility model also can be made various flexible mode, more than by the specific embodiment by accompanying drawing 1 illustrated embodiment, be that foregoing of the present utility model is done step detailed description, but this should be interpreted as that the scope of the theme that the utility model is above-mentioned only limits to described example.Do not breaking away under the above-mentioned technological thought situation of the utility model, various replacements and change according to ordinary skill knowledge and customary means are made all should be included in the scope of the present utility model.
