Fine, due to the size of the space is different. Based on the criteria of the Qing Dynasty, the size of the lining will be completed according to the specifications. However, the following problems exist in this situation: 1. Different sizes of lamps require different production lines or processing processes to increase production costs. 2. For those who do not have specifications (4), it often happens that the selected fixtures and lamp holders do not meet the specifications. This leads to the need to replace the appropriate lamps. This situation not only brings money to the _, but is more common in real life. . The situation of the second point of the eight on it, especially in the installation of a long type of lamp, the cover due to the conductive joints at both ends of the long lamp, and the mounting joint on the lamp holder are designed in the same scale, because of Such as the ease of production and the combination of the installation of simple / y dry type of this type of long tube is designed in a variety of styles, it is also because of this 'often the cost of the people do not (four) do not have the wrong performance. 201221842 [Description of the Invention] The main purpose of the present invention is to provide a telescopic tube having an adjustable length to facilitate mutual compatibility with lamp holders of different specifications. In order to achieve the above object, the telescopic lamp tube provided by the present invention comprises an outer tube and an inner tube which are sleeved and relatively displaceable with each other, wherein the outer tube is provided with a first luminous unit 7L, and the inner tube is internally mounted _ a second illuminating unit, and the second illuminating unit is electrically connected to the first illuminating unit in a manner that does not interfere with the first illuminating unit. According to the above concept, the present invention is a light-emitting panel, and the first-lighting single τ is also a led light panel, and the two LED light panels are respectively mounted in the outer tube and the inner tube in a misaligned manner. According to the above concept, the present invention further includes a galvanic hybrid, the two ends of the electrical connection are each a conductive end and the sub-division-light-emitting unit and the second illuminating unit are electrically connected. According to the above concept, the seam at the outer end of the invention is provided with a stop-ring ring, and a positioning ring is arranged at one end of the inner tube, and the service-stopping ring is abutted to prevent the outer tube from being separated from the inner tube. [Embodiment] In order to be more clear, this (four), _ touch and fit the diagram as detailed below. Referring to FIG. 1 and FIG. 2, the telescopic lamp tube of the preferred embodiment of the present invention should include an outer tube 1 (), an inner tube 2 〇, a first illuminating unit 3 〇, 201221842, and a second illuminating unit 7L. 40 and - electrical connection 5 〇; wherein: the outer tube 1 〇 has a closed end 12 and an open end Η, a material joint 16 _ no slab (not shown) outside the closed end 12, at the open end 14 The inner wall is finely provided - a rubber material is taken as an example but not as a stop ring 18, and a retaining ring 19 made of a rubber kick material is placed on the inner wall of the outer tube 1G. Keep a gap between them. The inner tube 20 has a closed end 22 and an open end 24, and a conductive joint 26 is disposed outside the closed end 22 for guiding the tube to the socket (not shown). The inner tube 20 is disposed in the outer tube 1G such that the outer (four) and the inner tube 2q are relatively displaceable with each other to change the distance between the conductive joint 16 and the conductive joint 26, that is, through the outer magnetic outer tube 10 and the inner tube 20 The docking state will enable the telescopic tube of this embodiment to be installed in a state-of-the-art manner. The inner tube 20 is fixed on the outer wall of the open end 24 with a rubber material as an example, but not limited thereto. The outer diameter of the positioning ring 28 is larger than the inner diameter of the stop ring α, 19 and smaller than the outer diameter. The inner diameter of the tube 1 has a stabilizing effect on the moving inner tube. The granule ring 28 is placed in the outer portion of the outer tube 1 before the outer tube 1Q is assembled with the sling ring 18, and is disposed in the outer portion. The movable range of the inner tube μ is restricted without being separated from the outer tube 10. In the first embodiment, the first light-emitting unit 3G and the second light-emitting unit (4) are respectively mounted in the inner portion 2 and the inner light-emitting unit (4), and are mutually advanced in a manner that does not advance each other. For example, a plurality of LEDs are mounted on a circuit board of 201221842, and the two lamps are mounted on the outer tube 1〇 and the inner tube 20 in a misaligned manner, so that the outer tube 1〇 and the inner tube can be avoided. The tube 20 undergoes an interference situation during the relative movement shown in FIG. In addition, the lengths of the LEDs in this embodiment are divided into the lengths of the outer tube 1G and the inner tube 2, so that when the telescopic tube 1 is at the maximum extension state shown in FIG. The light source will not be interrupted and can turn good lighting effects. The electrical connection 50 has good flexibility, and the two ends are - conductive ends 52, 54, and respectively (four) - the light-emitting unit 3G and the second light-emitting unit 40 are connected, as shown in FIG. 4 'at the telescopic tube 100 When the length is reduced, the f-connection 5〇 is appropriately folded without affecting the movement of the outer tube 1〇 and the inner tube 2〇. Therefore, the telescopic lamp of the present invention has the effect of adjustable length, is convenient to be compatible with the lamp holders of different specifications, and is used in an environment of different sizes and spaces, and the above is only for the purpose of (4) better (4) lying The equivalent structure and manufacturing method variations of the specification and the patent application are all included in the patent scope of the present invention. 201221842 BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a schematic view showing a telescopic tube in a maximum extension state according to a preferred embodiment of the present invention.
