Abstract

The invention discloses a high-luminous-efficiency white-light LAMP-LED structure and a packaging method, which solve the problems of poor wire soldering and poor luminous efficiency occurred in the white-light LAMP LED packaging process in the prior art. The white-light LAMP-LED structure comprises a flip LED chip, wherein the flip LED chip is mounted on a platform of a flat-headed type reversedL-shaped bracket; an LED fluorescent powder glue mixture wraps the flip LED chip and the upper end of the flat-headed type reversed L-shaped bracket to form a hemispherical LED fluorescent powder light emitting layer; epoxy resin coats the hemispherical LED fluorescent powder light emitting layer to form an epoxy resin lens; the flip LED chip and the platform of the flat-headed type reversed L-shaped bracket are connected by means of a die bonding solder paste; and the flat-headed type reversed L-shaped bracket is composed of a pair of matched flat-headed type reversed L-shaped positive electrode bracket and flat-headed type reversed L-shaped negative electrode bracket. The white-light LAMP-LED structure uses the flat-headed type reversed L-shaped bracket as a white-light LED packaging bracket, simplifies the die bonding and line welding process, improves the reliability of products, and greatly improves the luminous efficiency of a white-light LAMP LED.

Description

technical field [0001] The invention belongs to LED light source packaging technology, and relates to an LED packaging technology, in particular to an LED packaging material, an LED packaging process and an LED packaging structure. technical background [0002] LAMP LED, also known as plug-in light-emitting diode, is an energy-saving and environmentally friendly lighting material for visible light. It is a solid-state semiconductor device that can convert electrical energy into visible light. The light-emitting principle of LED is to pass current through the compound semiconductor, and through the combination of electrons and holes, the excess energy will be released in the form of light to achieve the effect of light. [0003] Commonly used general-purpose LAMP LED lamp beads are mainly composed of pin brackets, LED chips, gold wires and other materials. Common shapes include round head, square, bullet head and other shapes. It has the advantages of small size, light weigh...
