    摘要: An LED lamp (100) includes a plurality of LED modules (20) and a thermal module (30). Each of the LED modules has a plurality of LEDs (220). The thermal module is secured to a side of the LED modules. The thermal module includes a plurality of fins (320). The fins are stacked with one above another with a gap defined between two adjacent fins. Each of the fins defines two opening (325). The openings of the fins coincide with each other from top to bottom so as to form two channels (328). The channels are used for air to flow therein to exchange heat with the fins.

    摘要: An LED assembly (10) includes an LED (12) and a lens (16). The lens covers on an outer periphery of the LED. The LED has an encapsulant (125) and an LED chip (121) received in the encapsulant (125) and having a light emitting surface (122). The lens has a light output surface (161) over the light emitting surface. The light output surface defines a plurality of annular, concentric grooves (163). Each groove (163) is cooperatively enclosed by a first groove wall (165) and a second groove wall (166). The first groove wall is a portion of a periphery of an imaginary cone and a conical tip of the imaginary cone is located on the light emitting surface of the LED chip.

    摘要: A reading lamp (100) includes a lamp holder (20), a lampshade (40), a bracket (30) connecting the lamp holder with the lampshade, and a white light illuminator (50) received in the lampshade. The white light illuminator includes a light mixer (52), and at least a group of solid-state, light emitting elements (544) arranged to at least one side of the light mixer. The at least a group of solid-state, light emitting elements includes three kinds of solid-state, light emitting elements which respectively emit red, green and blue lights. The light mixer reflects, refracts and mixes the red, green and blue lights to obtain white light which directly radiates and spreads from a light emitting surface (521) of the light mixer.

    摘要: An LED lamp (100) includes a frame (12), at least one LED module (20), a heat sink (32) and a cover (50). The LED module has a plurality of LEDs (220). The heat sink is mounted on the frame. The at least one LED module is attached to a bottom of the heat sink, whereby heat generated by the LEDs can be dissipated by the heat sink. A heat pipe (35) interconnects the heat sink and the cover. Thus, the heat generated by the LEDs can also be dissipated by the cover via the heat pipe. The cover is secured so as to shield a top portion of the heat sink and space from the top portion of the heat sink.
