Abstract: A light-emitting diode (LED) lamp device includes at least one light-emitting module and a heat-dissipation module. The heat-dissipation module includes a plurality of cooling fins arranged in a radial pattern and connected annularly at intervals around the light-emitting module. Each of the cooling fins has an outer rim folded back a predetermined distance toward the light-emitting module to form a bent edge. The bent edges are formed with arcuate folded-back portions so that the cooling fins have rib-like outer perimeters after the bent edges are formed. Thus, the LED lamp device is allowed to be held safely by the folded-back portions while the cooling fins are structurally strengthened.

Abstract: A high power LED color bulb with infrared remote function has a reflector having front and rear openings and a light guide hole, a light guide bar received inside light guide hole, an LED module with LED chips and a bulb cover with a controlling circuit board. The LED module is mounted on a rear end of the reflector with the LED chips inside the reflector. The controlling circuit board is inside the bulb cover, is connected electronically to the LED module and has an infrared sensor aligned with the light guide bar of the reflector. When an infrared signal comes through the front opening of the reflector, the infrared signal passes through the light guide bar and is received by the infrared sensor. Since the infrared sensor is behind the reflector and the LED chips, the infrared sensor avoids overheating from heat produced by the LED chips and does not have to be replaced simultaneously with the color bulb.

Abstract: A LED illuminating device with rotating capability for showcases or the like is disclosed in the present invention comprising an enclosure with a rectangular shape in front view and side covers attached to both ends of the enclosure. A substrate is attached within the enclosure and a plurality of light emitting diode (LED) is formed on and along the substrate. A transparent front cover is attached to the front side of the enclosure and a rotator is connected to the enclosure to allow the enclosure being rotated via an axis to a desired angle.
