Problems solved by technology

5 watts is far from meeting the requirements of general lighting. If multiple 3-watt or 5-watt Luxeon LEDs are combined to achieve lighting, firstly, heat dissipation depends on an external heat sink; secondly, each Luxeon LED is a hemispherical sealed mirror design, its outgoing light angle reaches 180 degrees, and it must be equipped with various special lenses to meet various lighting requirements, so the entire light source will be very complicated, bulky and costly

Embodiment Construction

[0013] The present invention will be described in detail below with reference to the accompanying drawings: the light-emitting diode of the present invention is mainly composed of a light-emitting diode chip 11 and a metal base on which the light-emitting diode chip is installed. The metal base is composed of at least one hollow metal tube 12 with high thermal conductivity, and at least two LED chips 11 are fixed on one end or the center of the metal tube 12 . As shown in Fig. 2, 12 light-emitting diode chips 11 are directly welded on the tube wall surface of the metal tube 12 with gold-tin alloy or tin sheet with high thermal conductivity, or are bonded to the metal tube 12 with silver paste or organic or inorganic glue with high thermal conductivity. On the tube wall of the tube 12, a ring of diode chips is formed; the LED chips 11 are evenly distributed on the ring-shaped tube wall of the metal tube 12, and they are electrically connected to each other by gold wire 13 ball w...

Abstract

The light emitting diode mainly consists of light-emitting dies and a metal bed for mounting the die. The metal bed comprises at least one hollow high thermal conductivity metal tube. At least two light emitting diode dies are fixed on one end or center of said metal tube by welding said dies on the wall of said metal tube with gold-tin alloy, or bonding the dies on the wall of said metal tube with high thermal conduction silver paste or organic and inorganic adhesive. The said metal tube has fins or threaded heat-delivery surface. The lamp of light-emitting diode has at least one reflector with a reflecting surface made into parabolic shape mounted on said metal tube.

Description

technical field [0001] The invention relates to a light-emitting diode light source and a lamp made of it, in particular to a general-purpose high-power light-emitting diode light source and an assembled lamp, belonging to a light-emitting element. Background technique [0002] High-power light-emitting diodes, referred to as LEDs, have been widely known for their advantages and prospects as lighting sources, but they are still mainly used as some special light sources, such as automobile brake lights and flashlight lights. The most eye-catching high-power light-emitting diode is Luxeon LED designed and produced by Lumileds. Its structure diagram is as follows: figure 1 shown. It includes high-power light-emitting diode 1, silicon chip 2, metal base column 3, hemispherical sealing mirror 4, insulating material 5, gold wire 6 and electrode 7, etc. The high-power light-emitting diode 1 is mounted on a metal base 3 with a hemispherical sealed mirror 4 , the metal base is surr...
