Abstract: An LED module includes a substrate comprising a base plate and an elastic arm extending from a periphery side of the base plate. The elastic arm includes a horizontal portion parallel to and spaced from the base plate. A receiving space is defined between the horizontal portion of the elastic arm and the base plate. A circuit layer is formed on the base plate. An LED is mounted on the base plate and electrically connects with the circuit layer. The LED comprises a base and at least one electrode extending outwardly from the base. The LED is fixed on the substrate via the at least one electrode slideably received in the receiving space with a downward force applied on the electrode by the horizontal portion of the elastic arm.

Abstract: A method for manufacturing an LED (light emitting diode) includes following steps: providing a first electrode, a second electrode and a Zener diode, the Zener diode being electrically connected to the first and second electrodes; providing a mold; the first electrode, the second electrode and the Zener diode being received in the mold; injecting a liquid molding material into the mold, thereby integrally forming a base, a dam, and a reflective cup, the Zener diode being encapsulated in the dam; setting first and second LED chips respectively on the first and second electrodes; filling an encapsulation material in the reflective cup to encapsulate the first and second LED chips. The first and second LED chips are separated from each other by the dam.

Abstract: A method for manufacturing a light emitting diode is disclosed. Firstly, two leads each including a plateau are provided. A blocking layer is then formed on each plateau. A base is molded on the leads to embed the two leads therein, wherein the two blocking layer are exposed from the base. The blocking layers are removed from the plateaus so that the two plateaus are exposed. A light emitting chip is bonded on one plateau with a wire connecting the chip with the other plateau. Finally, an encapsulant is formed on the base to seal the chip and the wire.

Abstract: An LED device comprises a substrate, a circuit, two LED dies, a dam and a reflector. The dam divides the substrate into a first area and a second area, wherein one of the two LED dies is disposed on the first area and the other is disposed on the second area. The dam insulates radiant lights emitted from the two LED dies, whereby interference between the radiant lights can be prevented. Four separate electrodes are provided on the substrate, wherein one LED die is connected to two electrodes and the other LED die is electrically connected to the other two electrodes.

Abstract: A method for making a light emitting module includes: a. providing a flexible substrate; b. forming a plurality of rigid portions in the flexible substrate; c. forming an electrically conductive layer on the rigid portions, the electrically conductive layer having several electrodes apart from each other; d. arranging a plurality of LED dies on the electrically conductive layer with each LED die striding over and electrically connected to two neighboring electrodes; e. forming an encapsulating layer to cover the LED dies; and f. cutting through the flexible substrate. At least one of above steps b, c, d, e is performed by a roll applying process.

Abstract: An LED unit includes an LED and an optical element. The LED includes a substrate, an LED chip fixed on the substrate and an encapsulation encapsulating the LED chip. The LED further includes a first magnet fixed on the substrate. The optical element includes an optical adjustment layer and a second magnet. The second magnet attracts the first magnet to fix the optical element on the LED. The LED unit can be adjusted to have different optical characteristics by replacing the optical element thereof with another optical element.

Abstract: An exemplary LED module includes a board and an LED package mounted on the plate. The LED package includes a base, an LED chip mounted on a top surface of the base, two electrodes formed on the base and electrically connected to the LED chip and the board, and an encapsulant encapsulating the LED chip. A plurality of grooves are defined in the bottom surface of the base. When the LED package is secured on the plate via solder paste, the grooves function as a container for receiving excessive solder paste, thereby preventing the solder paste from spilling and floating or inclination of the LED package.

Abstract: A side-emitting LED includes a substrate formed with a plurality of electrodes, an LED chip bonded onto the substrate and electrically connected to the electrodes, a transparent member encapsulating the LED chip and a casing fixed on the substrate. The transparent member has a flat bottom surface attached to the substrate, a vertically surface extending perpendicularly from a straight side edge of the flat bottom surface and a curved surface connected to curved edges of the flat bottom and vertical surfaces. The casing encapsulates the transparent member excepting the vertical surface of the transparent member. The curved surface of the transparent member is shaped as a part of an outer surface of an ellipsoid.
