Taking the case that the lamp is placed opposite to the user, the first direction X is a left-right direction relative to the user, that is, the first side wall 123 is located at the left side or the right side of the user (the left side and the right side mentioned below are default to be the positions of certain elements in the lamp relative to the user when the lamp is placed opposite to the user, which will not be repeated). It should be noted that the housing 12 may further have other walls extending along the first direction X, and the housing 12 may not necessarily have a regular three-dimensional shape (for example, the lengths of the other walls and the first wall 121 may not be the same), so the overall length of the lamp cap 1 should be equal to the length of the longest one of all the walls of the housing 12 in the first direction X, so it can be understood that "the first length L1 of the first wall 121 is equivalent to the overall length of the lamp cap 1". The light source is installed in the housing 12, wherein the light source is, for example, a lamp installed in the housing 12, the lamp is disposed in a direction parallel to the first direction X, and the housing 12 includes a light emitting surface adjacent to or opposite to the first wall 121. In this embodiment, when the lamp holder 2 is placed on the desk surface, the light emitting surface faces the desk surface, and the light generated by the light source is emitted through the light emitting surface to illuminate the desk surface, so as to provide sufficient illumination for a user.

The operation panel 14 is mounted on the first wall 121, for example, the operation panel 14 may be fastened to the first wall 121 by a fastener, or may be adhered to the first wall 121 by spot gluing.

The operating portion 113 is rotatably installed in the fixed portion 112 and coupled with the encoder 114. Wherein at least a part of the operation portion 113 (for example, the part of the operation portion 113 also serves as a housing serving as the knob 11) is exposed outside the housing 12, and a user can hold the part of the operation portion 113 and rotate it; an encoder 114 is provided in the housing 12 for converting an angular displacement or a linear displacement generated when the operation portion 113 is rotated into an electric signal for adjusting the luminance or the color temperature of the light source. That is, the rotation of the operation portion 113 causes the encoder 114 to generate a corresponding operation signal, so that the rotation of the operation portion 113 can adjust the light-emitting brightness of the light source in the light-emitting brightness adjusting mode; and in the light-emitting color temperature adjusting mode of the light source, the rotation operation part 113 can adjust the light-emitting color temperature of the light source.
