Description

Telescopic tube

The invention relates to a lamp tube, and more particularly to a telescopic tube that is adapted to different environmental requirements and that can adjust the length of the tube.

Press, in different environments, different sizes of space, carefully selected lamps will be able to obtain good illumination to ensure the safety of indoor activities. However, due to the different sizes of space, based on the illumination and lighting range, there are many options for the size of the selected lamps. It is easy to say that the various lamps sold in the workshop are produced according to the specifications. However, this situation has the following problems:

1. Different sizes of lamps, each requiring a different production line or processing process, increasing production costs.

2. For those who do not have dark lamp specifications, it is often the case that the selected lamps and lamp holders do not meet the specifications, which necessitates returning to the original place of purchase to replace the appropriate lamps. This situation is not only inconvenient for consumers, but also more common. In real life.

Among them, the above-mentioned second point, in particular, occurs in the installation of a long type of lamp, the cover is designed because the conductive joints at both ends of the long lamp tube, and the mounting joints on the lamp holder are located on the same axis, because Such as the ease of production and the ease of installation, the size of this type of long tube is designed in a variety of ways, which is why it is often difficult for consumers to identify and derive the wrong purchase.

In view of this, the main object of the present invention is to provide a telescopic tube with 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 mutually displaceable, wherein a first light-emitting unit is disposed inside the outer tube, and a inner light-emitting unit is disposed inside the inner tube. The second light emitting unit is electrically connected to the first light emitting unit in such a manner as not to interfere with the first light emitting unit.

According to the above concept, the first light emitting unit of the present invention is an LED light board, and the second light emitting unit is also an LED light board, and the two LED light boards are respectively installed in the outer tube and the inner tube in a dislocation manner.

According to the above concept, the present invention further includes an electrical connection, wherein each end of the electrical connection is a conductive end and is electrically connected to the first light emitting unit and the second light emitting unit, respectively.

According to the above concept, the inner wall of one end of the outer tube is provided with a stop ring, and the outer wall of one end of the inner tube is provided with a positioning ring, and the stop ring and the positioning ring abut each other to prevent the outer tube from separating from the inner tube.

In order that the present invention may be more clearly described, the preferred embodiments are illustrated in the accompanying drawings. Referring to FIG. 1 and FIG. 2, the telescopic tube 100 of the preferred embodiment of the present invention includes an outer tube 10, an inner tube 20, a first illumination unit 30, a second illumination unit 40, and an electrical connection. 50; wherein: the outer tube 10 has a closed end 12 and an open end 14, and a conductive joint 16 is disposed outside the closed end 12 for guiding with the lamp holder (not shown), and the inner wall of the open end 14 is solid. A stop ring 18 is exemplified by a rubber material, but not limited thereto, and another rubber ring-shaped stop ring 19 is fixed on the inner wall surface of the outer tube 10, and the like is kept at a distance from each other. .

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 inserted into the outer tube 10 such that the outer tube 10 and the inner tube 20 are relatively displaced from each other to change the distance between the conductive joint 16 and the conductive joint 26, that is, by appropriately adjusting the outer tube 10 and the inner tube 20 to each other. The docking state between the two will enable the telescopic tube 100 of the present embodiment to be smoothly installed with lamp holders of different specifications.

The inner tube 20 is fixed on the outer wall of the open end 24 with a positioning ring 28 made of a rubber material, but not limited thereto. The outer diameter of the positioning ring 28 is larger than the inner diameter of the stop rings 18 and 19 and smaller than the outer tube 10 . The inner diameter has a stabilizing effect on the moving inner tube 20. The positioning ring 28 is located inside the outer tube 10 before the outer tube 10 is assembled with the outer ring 10 before the outer tube 10 is assembled with the outer ring 10, and the distance between the stop ring 18 and the stop ring 19 is matched. The movable range of the inner tube 20 is limited without being separated from the outer tube 10.

The first light emitting unit 30 and the second light emitting unit 40 of the embodiment are respectively installed in the outer tube 10 and the inner tube 20, and are designed in such a manner that they do not interfere with each other. Further, the light emitting unit is an LED. The light board is taken as an example, and a plurality of LEDs are mounted on a circuit board, and the two LED light boards are respectively installed in the outer tube 10 and the inner tube 20 in a dislocated manner, so that the outer tube 10 and the inner tube 20 can be avoided. An interference situation occurs during the relative movement shown in FIG. In addition, the lengths of the LED panels of the present embodiment respectively correspond to the lengths of the outer tube 10 and the inner tube 20, so that when the telescopic tube 100 is in the maximum extension state shown in FIG. 1, the illumination source does not There is an interruption and it can maintain good lighting effects.

The electrical connection 50 has good flexibility, and the two ends are electrically conductive ends 52 and 54 respectively, and are electrically connected to the first light emitting unit 30 and the second light emitting unit 40 respectively, as shown in FIG. When the 100 is in the reduced length, the electrical wires 50 are properly stacked without affecting the movement of the outer tube 10 and the inner tube 20.

Therefore, the telescopic lamp tube of the present invention has the effect of adjustable length, is convenient for mutual compatibility with lamp sockets of different specifications, and is suitable for environment use of different size spaces. The above description is only a preferred embodiment of the present invention. Variations in the equivalent structure and manufacturing method of the present invention and the scope of the patent application are intended to be included in the scope of the present invention.
