The two end covers are respectively disposed on the two ends of the lamp body, and each of the end covers is provided with an electrical contact for electrically coupling with an external power source. The lamp switching device includes a support rod, a bracket and a rotating element. The support rod portion is sleeved in the lamp body, and the rest of the support rod protrudes outside the lamp body. The bracket is disposed on a support rod located in the body of the lamp to support the lamp. The rotating element is disposed to protrude outside the body of the lamp On the support rod. When the rotating element is rotated, the support rod and the bracket can be rotated, and when the conductive pin of the end of the tube is rotated to engage with the electrical contact of the end cover, the tube is illuminated.

According to another embodiment of the present invention, the end cap has a ring-shaped groove for sliding both ends of the lamp tube in the annular groove, and the electrical contact is disposed on the annular groove.

According to another embodiment of the invention, the plurality of lamps are light-emitting diode lamps.

According to another embodiment of the present invention, the plurality of lamps are lamps of different illumination wavelengths, different color temperatures, or different illumination brightness.

According to another embodiment of the invention, the luminaire body is a hollow cylindrical housing.

According to another embodiment of the invention, each of the end caps is a round end cap.

According to another embodiment of the invention, the positions of the plurality of lamps are symmetrical with each other with reference to the center of the holder.

According to another embodiment of the invention, the end of each bracket is provided with a C-shaped tube clamp for holding the tube.

According to another embodiment of the invention, the end of each bracket is provided with an O-ring for inserting the lamp.

According to another embodiment of the present invention, the rotating component is a rotating handle, which is convenient for the user to rotate the handle to drive the support rod and the bracket to rotate to drive the lamp to rotate.

It can be seen from the above that the lamp of the switchable lamp tube of the present invention can simultaneously install a plurality of lamps with different illumination wavelengths, different color temperatures or different illumination brightness in the lamp body, and the user can use the lamp switching device. Select the desired wavelength of light, color temperature or brightness of the light bulb to achieve light The function of source type selection.

Please refer to FIG. 1 and FIG. 2 simultaneously. FIG. 1 is a perspective view of a lamp capable of switching a lamp according to an embodiment of the present invention, and FIG. 2 is an exploded view of the lamp of the switchable lamp of FIG. The luminaire 100 includes a luminaire body 101 and a lamp switching device 106. The lamp body 101 can be loaded with a plurality of lamps 108 of different illumination wavelengths, different color temperatures or different illumination brightness, and switched to the lamps of the desired illumination wavelength, color temperature or illumination brightness by the lamp switching device 106, thereby achieving the type of the light source. Selected features. The tube 108 can be a light-emitting diode tube or other tube that can provide different illumination wavelengths, different color temperatures, or different illumination levels. A pair of conductive pins 108a are respectively disposed at both ends of the lamp tube 108.

The two ends of the lamp body 101 are respectively covered by an end cover 103. The end cover 103 is provided with an electrical contact 104 for electrically coupling with an external power source. In this embodiment, the lamp body 101 is a hollow cylindrical case, and the end cover 103 is a circular end cover, but the lamp body and the end cover are not limited to the above-mentioned outer shape.

The lamp switching device 106 includes three parts: a support rod 106b, a bracket 106c, and a rotating element 106a. A portion of the support rod 106b passes through the through hole 103a of the end cover 103 and is sleeved in the lamp body 101. The remaining portion of the support rod 106b protrudes outside the lamp body 101. The bracket 106c is disposed on the support rod 106b located in the lamp body 101. The bracket 106c has a plurality of support portions 107, each of which supports a corresponding lamp tube 108. The rotating member 106a is disposed on a support rod 106b that protrudes outside the lamp body 101. When the rotating element 106a is rotated, the support rod 106b can be driven And the bracket 106c rotates. In this embodiment, the rotating element 106a is a rotating handle, which is convenient for the user to rotate the handlebar to drive the support rod 106b and the bracket 106c to rotate, thereby driving the plurality of lamps 108 to rotate.

Please refer to FIG. 3, which is a perspective view of the lamp body of the lamp of the switchable lamp of FIG. 1. When a plurality of lamps 108 are assembled in the lamp body 101, a plurality of lamps 108 are fixed to the brackets 106c. The end of the support portion 107, and the positions of the plurality of lamps 108 are symmetrical with each other with reference to the center of the holder 106c. Therefore, when the support rod 106b rotates, the bracket 106c will drive the plurality of lamps 108 to rotate at the same time.

Please refer to FIG. 4, which illustrates an end cover of a lamp body according to an embodiment of the invention. Each end cap 103 has a ring-shaped groove 103b therein for sliding both ends of the plurality of lamps 108 in the annular groove 103b. The annular groove 103b has a pair of electrical contacts 104a for electrically coupling with an external power source. When the lamp 108 conductive pin 108a is rotated to engage the electrical contact 104a of the end cap 103, the particular lamp is connected to the power source and illuminated.

Please refer to FIG. 5 and FIG. 6 simultaneously, which respectively show the brackets of the two lamps of the switchable lamp tube according to the embodiment of the present invention. A C-shaped lamp clip 107a is provided at the end of each of the support portions 107 of the bracket 106c' to detachably fix a lamp 108. The tube 108 can be detached from the opening of the tube clamp 107a. An O-ring 107b is disposed at an end of each support portion 107 of the bracket 106c", and a lamp tube 108 is detachably fixed. The lamp tube 108 can be inserted or removed from the annular opening of the O-ring 107b. And is fixed in the annular opening of the O-ring 107b. In practical applications, each support portion is not limited to only holding one lamp tube, and may also hold a plurality of lamps, so this embodiment is not Limited.

It can be seen from the above embodiments of the present invention that the switchable lamp to which the present invention is applied The tube lamp can be installed in a plurality of different illumination wavelengths, different color temperatures or different illumination brightness lamps in the lamp body, and the user selects the required illumination wavelength, color temperature or illumination brightness by means of the lamp switching device. The lamp is used to achieve the function of selecting the type of light source.

Although the present invention has been disclosed in the above embodiments, it is not intended to limit the present invention, and the present invention can be modified and modified without departing from the spirit and scope of the present invention. The scope is subject to the definition of the scope of the patent application attached.
