Abstract: A dual-use light fixture having AC and DC LEDs includes a heat-dissipating housing, a printed circuit board located on a first end of the heat-dissipating housing, AC and DC LED chips located on the printed circuit board, and a power supply pedestal coupled to a second end of the heat-dissipating housing. The power supply pedestal includes an AC plug, a DC driving unit, and a thread connector. The AC plug is electrically connected to the printed circuit board for inserting into an AC outlet to provide an AC power. The DC driving unit is located in an accommodating space formed by the power supply pedestal and the heat-dissipating housing and is electrically connected to the printed circuit board. The thread connector is coupled to another AC power, and the AC power is converted into a DC power by the DC driving unit.

Abstract: 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.

Abstract: A light emitting device comprising a carrier board, a first group of light emitting elements, a second group of light emitting elements and a driver circuit. The first group of light emitting elements includes a plurality of first LEDs disposing on the carrier board and are used for emitting a first color temperature light. The second group of light emitting elements includes a plurality of second LEDs disposing on the carrier board and are used for emitting a second color temperature light. The first LEDs and the second LEDs are disposed in an alternative arrangement. The driver circuit output a first and a second driving current to drives the first LED and the second LED respectively. When the first driving current is the maximum, the second driving current is the minimum, and vice versa. The minimum of the first driving current and the second driving current is not zero.
