New description: [New technical field] The new type is related to a kind of luminaire, especially a luminaire installed in a building or furniture. [Prior Art] A conventional lamp includes a base, a lamp cover fixedly coupled to the base, and a light-emitting unit mounted inside the lamp cover and capable of emitting light. • Although the 1 hai luminaire has a basic illuminating function, the illuminating unit can't be steered relative to the pedestal. Therefore, the light emitted by the illuminating unit can only be limited to one direction and cannot change its illumination range, which has limitations in use. . [New content] Therefore, the "fourth" of the present invention provides a luminaire capable of turning and changing the range of illumination. Thus, the novel lamp comprises a base, a push rod mounted on the base, a lamp cover locked to the support rod, and a light-emitting B unit. The base includes a surrounding wall and a mounting wall attached to a side edge of the surrounding wall. The pusher includes a shaft extending along a central axis and a joint coupled to the shaft and extending along an upright axis of the __. The shaft has a fastening portion that is locked to the mounting wall and a steering portion that connects the fastening portion. The joint is coupled to the steering portion and rotatable relative to the shaft between a first position and a second position. In the first position, the upright axis forms an angle with the central axis. Greater than 『 3 M436782 but less than 18 〇. The upright axis overlaps the central axis in the second position. The joint also has a lock cover portion remote from the shaft. The lamp cover is rotatable relative to the shaft through the joint, and includes a cover body locked to the lock cover portion, and an outer cover covering the end of the cover body away from the lock cover portion. The cover and the cover jointly define a light-emitting chamber. The light-emitting unit is mounted in the light-emitting chamber and emits light and is emitted from the outer cover. The beneficial effect of the novel is that the lamp cover can be rotated relative to the shaft through the design of the support rod, so that the illumination range of the lamp can be turned and changed, and the use is more flexible. The above and other technical contents, features and effects of the present invention will be apparent from the following detailed description of the preferred embodiments. Referring to FIG. 1 , FIG. 2 and FIG. 3 , a preferred embodiment of the present luminaire is adapted to be electrically connected to a power supply unit not shown. The power supply unit may be a battery or a power socket. It can be used as a wall lamp on the wall or as a table lamp on the table. Of course, the position can be adjusted according to the user's needs. The reference diagram of the lamp in this embodiment is illustrated by taking a wall lamp as an example, and includes: a base cymbal, a branch pole 2 mounted on the base cymbal 2, a lamp cover 3 locked to the support rod 2, and a light unit 4, the base 1 including a frustoconical surrounding wall丨丨, a 4 M436782 is connected to the _ 6 power supply unit surrounding the wall 1 and partially exposed 2: the wall 12, and a power switch 13 electrically connected to the wall 12 of the attire. The support rod 2 includes a > _ y y. A shaft 21 extending from a central axis A, and a joint 22 extending rotatably connected to B. is attached to the body 21 and along the vertical axis of the strip Wherein, the shaft, Αβ 911 β has a solid interface 211 211 ' locked to the mounting wall 12 and a steering portion 212 connected thereto. The fixing portion allows the working cylinder to pass through The bolt 5 is locked to the mounting wall 12, but it is known that the locking method does not need to be locked. The turning portion 212 is rotatably sleeved! and is restrained from being detached from the solid when rotated. The θ a limit mode is a conventional technique, and therefore is not described in detail here. The rotation feature of the turn portion 212 is described later, and the steering portion commits and has a 214° spherical groove 213 which is concave. The steering (4) is away from the end of the fixing portion 211. The supporting groove 214 is connected to the outer side from the periphery of the spherical groove 213. The joint 22 is connected to the turning portion 212 and has a matching spherical groove 213. And the spherical pivot portion 丨 转 4 221 ' and one away from the shaft 21: cover 222. The spherical recess 213 of the turning portion 212 allows the first position of the insertion portion and a first axis B and the central axis A to form one another: Γ = υ :: 刚. 'In the second position (see Figure 4) the upright axis... the central axis Α overlaps, that is to say the angle is that the striker groove 214 can limit the joint 22 when the joint 22 is the second The joint is rotatably engaged to rotate the joint 22 relative to the shaft. Fang 兮 · potential, paying the erect first / if in the first position - plus enough - /, "* „ 5 position in the direction of the first position, the stop groove of this embodiment 214 will stop the joint 22 from continuing to rotate when the angle is 90°, but the stop groove 214 can also be designed to stop the joint 22 from continuing to rotate at other angles. 3 is rotatable relative to the shaft 21 through the joint 22, and includes a cover 31 locked to the lock cover portion 222, and a cover covering the cover 31 away from the end of the lock cover portion 222 32. A transparent dust cover 33. The cover 31 is screwed to the lock cover portion 222 and connected to the joint 22. The cover 31 and the outer cover 32 together define a light-emitting chamber 310. The cover 32 is annular and defines an opening 311 that communicates with the light-emitting chamber 31. The dust cover 33 is attached to the opening 31 of the outer cover 32. The light-emitting chamber 310 is sealed to prevent dust. Sand or mosquito enters the light-emitting chamber 310. The light-emitting unit 4 is installed in the light-emitting chamber 31〇 and transmits through The wire is electrically connected to the power supply device, and emits light and emits light from the outer cover 32. The manner in which the wire is electrically connected to the power supply device is a conventional technique, and thus is not described here. The light-emitting unit 4 includes a circuit board 41 embedded in the cover 31 and at least one light-emitting diode 42 electrically connected to the circuit board 41. However, the light-emitting unit 4 can also be presented in other aspects. For example, the light-emitting unit 4 includes a light bulb, and therefore need not be limited to the embodiment. Referring to FIG. 2, FIG. 3, FIG. 5, another effect of the turning portion 212 is further described: the turning portion 212 can be wound around The central axis A rotates relative to the fixing portion 211. Since the lamp cover 3 is connected to the joint 22, M436782 and the joint 22 is connected to the rotation (four) 212 of the shaft 21, when the steering portion 212 rotates, The joint 22 and the lampshade 3 can be circularly moved around the central axis a, as shown by the direction of the arrow, thereby providing another function of changing the illumination angle. When the present invention is used, the lamp is electrically connected first. In the power supply unit, Then, the power switch 13 is pressed to cause the light-emitting unit 4 to start to emit light, and the shaft 2 of the support rod 2 is applied to the edge of the cover, so that the joint 22 is opposite to the shaft 21 In the [position and the second position, the door is rotated to adjust the illumination angle of the light-emitting unit 4. In addition, one hand: the s earth seat 1 3 hands against the edge of the outer cover 32, so that the lampshade 3 and the joint 22 follow The steering portion 212 is rotated, that is, the circular motion is centered on the central axis A, and the illumination angle of the illumination unit 4 is adjusted. In summary, the new luminaire has a (four) joint 22 relative to the shaft η. The turning effect and the rotation effect of the turning portion 212 relative to the fixing portion allow the user to arbitrarily adjust the lighting unit 4 to a desired angle, and can indeed change the illumination range of the lamp. However, the above is only the preferred embodiment of the present invention, and the scope of the present invention cannot be limited thereto, that is, the simple equivalent change and modification of the novel application and the novel description. All remain within the scope of this new patent.
