## Abstract

A lamp includes a rotary adjustment mechanism, an inclination adjustment mechanism and a light source. The light source is rotatable along a first direction in a first plane by the rotary adjustment mechanism and/or rotatable relative along a second direction in a second plane by the inclination adjustment mechanism, wherein the second plane is different from the first plane.

## Claims

### Claim 1

A lamp, comprising:
a lamp base,
a case body;
a rotary adjustment mechanism;
an inclination adjustment mechanism;
a light source which is rotatable along a first direction in a first plane by the rotary adjustment mechanism and/or rotatable along a second direction in a second plane by the inclination adjustment mechanism, wherein the second plane is different from the first plane; and
a spherical shell, wherein the light source is disposed on the spherical shell;
wherein the rotary adjustment mechanism connects the lamp base and the case body, thereby enabling the case body to rotate relative to the lamp base along the first direction in the first plane; and
wherein the inclination adjustment mechanism connects the case body to the spherical shell, thereby enabling the spherical shell to rotate relative to the case body along the second direction in the second plane;
wherein the rotary adjustment mechanism comprises:
at least one first sliding chute passing through a bottom portion of the lamp base; and
at least one first fixing member moveably disposed through the first sliding chute and fixed on the case body; and
wherein the first sliding chute has two ends and one path between the two ends, and the path extends curvedly along the first direction.

### Claim 2 (depends on 1)

The lamp of claim 1, wherein the case body has a top portion and at least one convex post extending from the top portion, and the first fixing member is fixed on the convex post.

### Claim 3 (depends on 1)

The lamp of claim 1, wherein the inclination adjustment mechanism comprises:
at least one second sliding chute disposed at the case body;
at least one sliding member slidably disposed in the second sliding chute; and
at least one second fixing member which is correspondingly disposed through the sliding member and the second sliding chute and is fixed on the spherical shell.

### Claim 4 (depends on 3)

The lamp of claim 3, wherein the sliding member is a resilient pad.

### Claim 5 (depends on 1)

The lamp of claim 1, further comprising a positioning ring disposed between the lamp base and the case body.

### Claim 6 (depends on 1)

The lamp of claim 1, wherein the first sliding chute is semicircle arc shaped.

### Claim 7 (depends on 1)

The lamp of claim 1, wherein the first fixing member is disposed through the first sliding chute and is fixed on the case body.

### Claim 8

A lamp, comprising:
a lamp base,
a case body;
a rotary adjustment mechanism;
an inclination adjustment mechanism;
a light source which is rotatable along a first direction in a first plane by the rotary adjustment mechanism and/or rotatable along a second direction in a second plane by the inclination adjustment mechanism, wherein the second plane is different from the first plane; and
a spherical shell, wherein the light source is disposed on the spherical shell;
wherein the rotary adjustment mechanism connects the lamp base and the case body, thereby enabling the case body to rotate relative to the lamp base along the first direction in the first plane; and
wherein the inclination adjustment mechanism connects the case body to the spherical shell, thereby enabling the spherical shell to rotate relative to the case body along the second direction in the second plane;
wherein the rotary adjustment mechanism comprises:
at least one first sliding chute passing through a bottom portion of the lamp base; and
at least one first fixing member moveably disposed through the first sliding chute and fixed on the case body;
wherein the inclination adjustment mechanism comprises:
at least one second sliding chute disposed at the case body;
at least one sliding member slidably disposed in the second sliding chute;
at least one second fixing member which is correspondingly disposed through the sliding member and the second sliding chute and is fixed on the spherical shell; and
wherein the case body has a top portion, and the top portion is corresponding to the arc shape of the spherical shell, wherein the second sliding chute is disposed on the top portion.

### Claim 9 (depends on 8)

The lamp of claim 8, wherein the second sliding chute has two ends and one path between the two ends, and the path extends curvedly on the top portion along the second direction.

### Claim 10 (depends on 8)

The lamp of claim 8, wherein the second sliding chute is semicircle arc shaped.
