摘要： A light emitting device comprising a first frame, a light bar and a light guide plate is provided. The first frame has a groove which has a bottom plane, two inner walls, and an opening. The light bar disposed in the groove comprises a substrate having a lower surface attached to the bottom plane and an upper surface having several light sources. The light guide plate has a light emitting surface and a light incident surface. The light incident surface perpendicular and adjoining to the light emitting surface has several abutting portions. The light guide plate is inserted to the groove via the opening. The emitting light of the light source entering the light guide plate is guided by the light guide plate to be emitted off the light emitting surface. The abutting portions abut to the upper surface, so that the light bar is fixed in the groove.

摘要： The present application relates to an illumination device (100) having a light source module (200), a power supply module (300), a driving module (400), a control module (500) and a start module (600). The driving module (400) outputs a driving current (D) to the light source module (200) based on a power supply from the power supply module (300). The control module (500)controls the magnitude of the driving current (D) based on a first voltage signal (C) generated by the power supply module. After receiving the first voltage signal (C), the control module (500) controls the driving module (400) to steadily increase the driving current in a first stage output. After receiving the first voltage signal (C) again, the control module (500) controls the driving module (400) to output a constant driving current equal to the driving current (D) at the end of the first stage.
