Abstract

An LED fixture capable of performing light-beam adjustment includes a lamp holder and a lamp cover. One side of the lamp holder is arranged an illuminating module having an LED lamp that is arranged on the illuminating module with an angle. The lamp cover is connected to the lamp holder, while the illuminating module is accommodated in the lamp cover. A reflecting face with a specific curvature is arranged on an inner face of the lamp cover in a way, such that the illuminating direction of the LED lamp is toward the reflecting face, making a light irradiated from the LED light source able to be reflected outwardly by the reflecting face. Since the lamp holder and the lamp cover are movably combined through a mobile manner, when the lamp holder or the lamp cover is rotated, the relative position between the LED light source and the reflecting face is changed, thus that a variation of illuminating ranges is formed.

Claims

1. An LED fixture capable of performing light-beam adjustment, including

a lamp holder, one side of which is arranged an illuminating module having an LED lamp, the LED lamp being arranged at the illuminating module with an angle relative to a horizontally forward line;

and

a lamp cover, which is movably combined to the lamp holder and can be moved through a left-and-right rotary manner, while the illuminating module is accommodated in the lamp cover;

wherein a reflecting face with a specific curvature is arranged on an inner face of the lamp cover and the illuminating direction of the LED lamp is toward the reflecting face, making the light irradiated from the LED light source able to be reflected outwardly by the reflecting face, when rotating the lamp cover, the relative position between the LED light source and the reflecting face being also changed, thus a variation of illuminating ranges being formed.

2. The LED fixture capable of performing light-beam adjustment according to claim 1, wherein the illuminating module further includes a cooler connected to the LED lamp and a circuit device providing a power source needed by the LED lamp.

3. The LED fixture capable of performing light-beam adjustment according to claim 1, wherein the reflecting face is a smooth face that has a specific curvature.

4. The LED fixture capable of performing light-beam adjustment according to claim 1, wherein the reflecting face is a rough face that has uneven stripes.

5. The LED fixture capable of performing light-beam adjustment according to claim 1, wherein the LED is arranged at the illuminating module with an angle ranging from 75 degrees to 105 degrees.

6. An LED fixture capable of performing light-beam adjustment, including

a lamp holder, one side of which is arranged an illuminating module having an LED lamp, the LED lamp being arranged at the illuminating module with an angle relative to a horizontally forward line;

and

a lamp cover, which is movably combined to the lamp holder in a way, such that the combined lamp holder can rotate with respect to the lamp cover, making the LED lamp of the illuminating module rotated in the lamp cover;

wherein a reflecting face with a specific curvature is arranged on an inner face of the lamp cover, making the light irradiated from the LED light source able to be reflected outwardly by the reflecting face, when rotating the LED lamp, the relative position between the LED light source and the reflecting face being changed, thus a variation of illuminating ranges being formed.

7. The LED fixture capable of performing light-beam adjustment according to claim 6, wherein the illuminating module further includes a cooler connected to the LED lamp and a circuit device providing a power source needed by the LED lamp.

8. The LED fixture capable of performing light-beam adjustment according to claim 6, wherein the reflecting face is a smooth face that has a specific curvature.

9. The LED fixture capable of performing light-beam adjustment according to claim 6, wherein the reflecting face is a rough face that has uneven stripes.

10. The LED fixture capable of performing light-beam adjustment according to claim 6, wherein the LED is arranged at the illuminating module with an angle ranging from 75 degrees to 105 degrees.
