s302, the driving power board 2 connected with the metal wire 3 is inserted into the lamp tube 1, and the silicone adhesive 7 is contacted with the inner wall of the lamp tube 1. The heat generated by the light emitting element 23 and the driving element 22 on the printed circuit board 21 can be rapidly transferred to the lamp tube 1, and the lamp tube 1 is exposed to the air to dissipate the heat to the air. The silicone adhesive 7 can be used as a buffer to prevent the printed circuit board 21 from colliding with the inner wall of the lamp tube 1.
It is to be understood that aspects of the present invention may be practiced otherwise than as specifically described.
It should be understood that the above examples are merely examples for clearly illustrating the present application, and are not intended to limit the embodiments of the present application. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present application shall be included in the protection scope of the claims of the present application.
