Description

TECHNICAL FIELD

[0001] The utility model relates to a lighting device, in particular to a light emitting diode lighting device with a fixed clamping groove. BACKGROUND

[0002] The existing light emitting diode lighting device usually adopts a hard circuit board. However, the hard circuit board has a high cost and occupies a large space. In addition, the hard circuit board is not resistant to bending and has a complex installation procedure. Therefore, the overall cost of the existing light emitting diode lighting device is also increased.

[0028] The cross section of the tube body 11 is circular, and the tube body 11 has two extension plates 111. The two extension plates 111 are arranged on the inner wall of the tube body 11 and are opposite to each other to form a fixed clamping groove FG.
