  • Publication number: 20130043493
    Abstract: A light-emitting diode (LED) structure includes a substrate, a plurality of LED chips, a first colloid, a second colloid, and a lens. The substrate is provided with at least one retaining section, and the LED chips are mounted on the substrate and covered by the first colloid. The second colloid is located to one side of the first colloid opposite to the substrate. The lens is provided with at least one catching section correspondingly engaged with the at least one retaining section, so that the lens is connected to the substrate to form a unitary body through engagement of the catching section with the retaining section and closes the LED chips, the first colloid and the second colloid in between the lens and the substrate. With these arrangements, the LED structure can have upgraded lighting efficiency and allows quick change of LED color temperature or LED beam angle.

  • Publication number: 20120147586
    Abstract: The present invention relates a LED module and a lamp having the same. The LED module includes a substrate, a reflector, a transparent shroud and a fluorescent gel layer. The substrate has an accommodating portion in which at least one LED chip is received. The reflector is provided on the substrate and has an accommodating space in which a first gel is received. The transparent shroud is connected to the reflector to seal the first gel. The fluorescent gel layer is provided between the transparent shroud and the first gel. With this structure, light spot and color temperature of the emitted light become more uniform, and the light-emitting efficiency thereof is improved greatly.
