The surface light source lamp has the benefits that the whole surface shines, the shining is uniform and is not dazzling, the heating is small, and the lighting effect is high, therefore, the surface light source lamp is suitable for the input of the mains supply, and solves the weakness in the punctuated light source.
Description
Technical field
The utility model relates to a kind of lighting, relates in particular to a kind of LED area source lamp.
Background technology
All belong to point source of light in the existing LED cup lamp, though it is big to have overcome power consumption, the weakness of generate heat serious and low light efficiency, the central light strength height of the light that point source of light sends when naked eyes are directly seen LED point-like light emitting source, has very big infringement to naked eyes.
The utility model content
The utility model is to overcome above-mentioned weak point, and purpose is to provide a kind of LED area source lamp of suitable mains supply input, and whole of this LED area source lamp is luminous, luminous even, not dazzling, it is little to generate heat, the light efficiency height has solved problems of the prior art.
The utility model is to achieve the above object by the following technical programs: a kind of LED area source lamp, comprise: LED area source, LED area source constant-flow driver, Lamp cup, described LED area source constant-flow driver comprises drive circuit, constant-current control circuit, wherein drive circuit is electrically connected with constant-current control circuit, LED area source, and constant-current control circuit is electrically connected with the LED area source.
As preferably, LED area source constant-flow driver also comprises short-circuit protection circuit, open loop protection circuit, and drive circuit is electrically connected with short-circuit protection circuit, open loop protection circuit, and short-circuit protection circuit, open loop protection circuit are electrically connected with the LED area source.
The beneficial effects of the utility model: whole luminous, and luminous evenly not dazzling, it is little to generate heat, and the light efficiency height is fit to the mains supply input, solved the above weakness that point source of light exists.
Description of drawings
Fig. 1 is the fundamental diagram of LED area source lamp constant-flow driver;
Fig. 2 is the circuit diagram of LED area source lamp constant-flow driver;
Fig. 3 is the structural representation of GU10 type LED area source lamp;
The specific embodiment
Below in conjunction with specific embodiment the utility model is described further, but protection domain of the present utility model is not limited in this:
Embodiment 1: as shown in Figure 1; a kind of LED area source lamp; comprise: LED area source, LED area source constant-flow driver, Lamp cup; described LED area source constant-flow driver comprises drive circuit, constant-current control circuit, short-circuit protection circuit, open loop protection circuit; wherein drive circuit is electrically connected with constant-current control circuit, short-circuit protection circuit, open loop protection circuit, LED area source, and constant-current control circuit, short-circuit protection circuit, open loop protection circuit are electrically connected with the LED area source.
As shown in Figure 2, the civil power input outputs to electrolysis EC1 and carries out filtering after diode rectifier bridge heap DB1 rectification, behind DB1 and EC1 rectifying and wave-filtering, form a direct-current power supply and give late-class circuit, by drive IC--U1, transformer T1, shunt capacitance C1, commutation diode D1 and filtering electrolysis EC2 constitute the AC--DC drive circuit, by a reference source U3, filter capacitor C2, resistance R 1, R2 constitutes output voltage sampling circuit, the voltage signal that obtains feeds back to IC through photoelectric isolating coupler U2, regulates constant voltage output when forming open circuit through the IC internal control circuit, and output voltage is unlikely too high when guaranteeing LED area source open circuit or connecing the back.When the LED area source is correct insert after, the electric current that flows through the LED area source is through current sampling resistor R5, R6, R7 adopt current signal feed back to the EN/UV pin of U1 through photoelectric isolating coupler U2, realize that constant current drives thereby regulate through the IC internal control circuit.When output short-circuit, photoelectric isolating coupler U2 action makes drive IC be in conducting state, thereby realizes short-circuit protection.
Structural representation when as shown in Figure 3, the LED area source of LED area source lamp and GU10 Lamp cup mate.Herein LED area source and Lamp cup comprise various caliber sizes.
Above described be specific embodiment of the utility model and the know-why used; if comply with the change that conception of the present utility model is done; when the function that it produced does not exceed spiritual that specification and accompanying drawing contain yet, must belong to protection domain of the present utility model.
