Near-infrared illuminator

A low profile LED lamp bulb with high efficient heat dissipation is disclosed. Each of the lead frame unit has a top-down tapered metal section on bottom end adaptive for being bent inwards to form a lead frame bottom cup suitable for fitting in the low profile LED lamp. A modification embodiment is that a heat sink independent from electrode is attached to a backside of the lead frame with nonconductive adhesive material, heat and electricity are independent from with each other, so that no interference between heat and electricity, and heat can be dissipated mainly from the heat sink.

Low profile LED lamp

A low profile LED lamp with high efficient heat dissipation is disclosed. Each of the lead frame unit has a left top metal section, left middle metal section, right top metal section, and a top-down tapered metal section. The top-down tapered metal section is bent inwards to form a lead frame bottom cup which is suitable for fitting in the low profile LED lamp.

Low profile LED lamp bulb

An air-cooled lamp bulb includes a central tube and a circular light wall. The circular light wall is formed by a plurality of light units surrounding the central tube and emitting light beams in a direction away from the central tube. A top frame supports the circular light wall on top. A top opening is formed in the top frame. A bottom gap is formed between a bottom of the central tube and a bottom of the circular light wall. An air passage is formed between the central tube and the circular light wall. The air passage connects the top opening and the bottom gap for allowing air flow through the air-cooled lamp bulb.

Air-cooled LED lamp bulb

An air-cooled lamp bulb includes a central tube, a circuit board disposed inside the central tube, a circular light wall surrounding the central tube, a transparent dome surrounding a top end of the circular light wall and having a top central opening, and a first air passage formed between the central tube and the circular light wall. The circular light wall is formed by a plurality of light units arranged side by side. Each of the light units has a light source mounted adjacent a top end of the central tube. The transparent dome is arranged for modifying light emitted by the light sources. The first air passage allows air flow through the air-cooled lamp bulb.

A LED lamp is disclosed which has a plurality of light unit, each of the light unit has at least one flat metal lead for heat dissipation and the lower part of the metal lead is mounted on a heat sink for a further heat dissipation.

LED lamp

An air cooling LED lamp is disclosed. The lamp has air passages for natural air flow for cooling the lamp without using any electric fan to reduce electric energy consumption. The air passages still work for natural air cooling for the lamp when the lamp is configured either in a top down position or in a lateral position.

Air cooling LED lamp

A LED lamp is disclosed which is composed of a plurality of light unit, each of the light unit has metal its leads inserted into a heat sink for heat dissipation. A circuit board is optionally to use for electrically coupling the metal leads of each light unit to a control circuit for controlling the on/off of each of the light units.

Heat sink for LED lamp

A panorama lamp with 360 degree peripheral illumination with reference to an axis of the lamp is disclosed. Each of the light units mounted on a heat sink has a light chip facing outward from the lamp. Either a protection cap or a circular wall lens can be optionally adopted to cap the top of the lamp. The protection cap provides protection to the chips of the lamp from being damaged. The circular wall lens modifies the beam profile of the lamp to meet various market requests.

Panorama lamp with 360 degree peripheral illumination

A LED tube having double heat sinks is disclosed. One of the embodiment shows a first plurality of light unit is fixed onto the top heat sink, and a second plurality of light unit is fixed onto the bottom heat sink, while with the light chips configured in between the two heat sinks for light emission to the ambient.

Double heat sink LED tube

A light source device having a good heat dissipation capability is disclosed, in which heat generated by a light emitting device is conducted to a base fabricated by a porous material through a heat conducting mask or a heat conducting pipe. Due to a large area contact between the heat conducting mask or the heat conducting pipe and the base, the heat can be evenly conducted to the base, so that the base can absorb the heat and dissipate the heat to external, so as to improve a heat dissipation efficiency. Moreover, in the light source device of the disclosure, heat exchange of the light emitting device can be directly carried on through air convection, so that the heat generated by the light emitting device can be taken away from the light source device through heat exchange of cool air.

Light source device

A light emitting device and the fabrication method includes forming one or more light emitting modules on a substrate. The light emitting module receives an alternating current input and has at least two micro diodes. Each micro diode has at least two active layers and is electrically connected by a conductive structure so as to allow the active layers of the micro diodes to alternately emit light during positive and negative cycles of the alternating-current input.

Alternating current light emitting device

A light emitting diode (LED) package comprising a carrier, an LED chip, a lens, and a phosphor layer is provided. The LED chip disposed on the carrier. The lens encapsulating the LED chip has a plurality of fins surrounding the LED chip and a conical indentation. The fins extending backward the LED chip radially. Each of the fins has at least one light-emitting surface and at least one reflection surface adjoining the light-emitting surface. A bottom surface of the conical indentation is served as an total reflection surface. The phosphor layer is disposed on the light-emitting surfaces of the lens. An LED package and an LED module are also provided.
