The detailed description of the preferred embodiments of the present invention will be apparent from the detailed description of the preferred embodiments. It should be noted that, before the detailed description, similar elements are denoted by the same reference numerals.

Referring to FIG. 2 to FIG. 4, a preferred embodiment of the illuminating device of the present invention comprises a lamp tube 2, an illuminating unit 3 disposed in the tube 2, and an electrode holder disposed at one end of the tube 2. 4. An adapter 5 for mounting the lamp 2, a transformer unit 6 disposed in the adapter 5, and a stopper 7 disposed at one end of the tube 2.

As shown in FIG. 2 and FIG. 3, the lamp tube 2 includes a tube wall 21 defining an accommodating space, a first end portion 22 at one end of the tube wall 21, and a tube wall 21. The second end portion 23 of the other end is disposed in the accommodating space. The electrode holder 4 is disposed on the first end portion 22 of the tube 2, and the blocking member 7 is disposed on the second end portion 23 of the tube 2. The electrode holder 4 and the stopper 7 are disposed at both ends of the tube 2 to form a waterproof state of the tube 2. The material of the blocking member 7 can be metal, plastic, or other polymer materials. The circumferential surface of the electrode holder 4 is a first electrode 41. The end surface of the electrode holder 4 is a second electrode 42. The first electrode 41 and the second electrode 42 are electrically connected to the light emitting unit 3. In the embodiment, the second electrode 42 is located at the center of the end surface of the electrode holder 4.

Referring to FIG. 2 and FIG. 4, the adapter 5 is T-shaped and includes a connecting portion 51 for engaging the electrode holder 4, and a connection with the connecting portion 51 for accommodating the transformer unit 6. Part 52. The connecting portion 51 has a guiding portion 511, and the transforming unit 6 is electrically connected to the guiding portion 511 of the connecting portion 51. When the electrode holder 4 is screwed to the connecting portion 51 of the adapter 5 as shown in FIG. 4, the first electrode 41 will be The guiding region 511 is in contact with the conduction, so that the first electrode 41 and the second electrode 42 can be electrically connected to the transformation unit 6.

In addition, the connecting portion 51 is spaced apart from the plurality of grooves 512. The mounting portion 52 of the adapter 5 has an opening 521 communicating with the outside, and the wire for the transformer unit 6 is extended by the opening 521 and A power supply (not shown) forms an electrical connection.

According to the above structural description, the lighting device of the present invention has the following advantages:

1. The transformer unit 6 can be easily replaced. In order to apply to different installation environments, the diameter of the tube 2 has a tendency to be fine. When the tube diameter is too small, the transformer unit 6 is not easily placed. In addition, in the present invention, by designing the transformer unit 6 to be externally disposed in the adapter 5, in addition to solving the problem that it is difficult to place the transformer unit 6 in the small tube 2, the transformer unit 6 is also made. The replacement is more convenient.
