Abstract

The invention relates to an ultra-small ultra-thin high-luminous-efficiency lateral-emission-type high-light white-light LED element which comprises a substrate and a light-emitting LED chip. The light-emitting LED chip is fixed on the substrate; the substrate is provided with a plurality of via holes running through the upper and lower surfaces thereof; each via hole is filled with an electric conductor; the positive electrode of the light-emitting LED chip is electrically connected with the electric conductor in one of the via holes through a positive wire; and the negative electrode of the light-emitting LED chip is electrically connected with the electric conductor in another one of the via holes through a negative wire. The provided ultra-small ultra-thin high-luminous-efficiency lateral-emission-type high-light white-light LED element is ultra-thin in thickness and good in heat radiation effect.

Description

technical field [0001] The invention relates to an ultra-small, ultra-thin, high-efficiency side-emitting high-brightness white LED element, in particular to a small side-emitting LED element. Background technique [0002] At present, there are two types of small side-emitting LED indicators on the market: [0003] (1) Bracket type: mainly use PPA resin + copper bracket as the substrate, the main dimensions are 020 (3.8*1.05*0.6mm), 010 (3.8*1.0*0.4mm), 215 (2.8*1.0*0.9mm), 335 (3.8*0.6*1.2mm), its size is relatively large, and the bracket-type side-firing LEDs are mainly concentrated in the 020 and 010 models, but the thinnest thickness is 0.4mm. [0004] (2) PCB type: mainly use BT resin as the substrate, the main dimensions are 0603 (1.6*1.1*0.6mm), 0805 (2.0*1.1*0.6mm), 1204 (3.0*1.5*1.0mm), PCB type side Due to the large size of the traditional process and the high thermal resistance of the PCB, the high-brightness white light cannot solve the heat dissipation problem...
