Abstract

The invention provides a light emitting diode device which comprises a transparent base plate, a plurality of light emitting diode chips, a circuit and a transparent colloid, wherein the light emitting diode chips are fixedly connected to the transparent base plate; the circuit is formed on the transparent base plate and is electrically connected to the light emitting diode chips; and the transparent colloid is used for packaging the light emitting diode chips. The light emitting diode chips are used for generating light rays with at least one type of wavelength, and the light generated by the light emitting diode chips is respectively emitted to two opposite surfaces of the transparent base plate. The blue light chips are welded on the circuit of the transparent base plate, the fluorescence material is matched and coated, and the advantages of the base plate are utilized, therefore the double-surface white light emitting device packaged by the chips is manufactured.

Description

technical field [0001] The present invention relates to a light emitting diode (light emitting diode, LED) device and its packaging method, especially to a light emitting diode device that can be used as a double-sided white light emitting device and its packaging method. Background technique [0002] Compared with traditional light sources such as cold cathode tubes, LED packaging components have small size, low power consumption, high brightness, high color performance, fast response (can be operated at high frequency), environmental protection (shock resistance, impact resistance and not easy to break) , recyclable) and easy to develop into light, thin and short products and other advantages, so LED light source has a certain market advantage. Generally speaking, a traditional LED packaging assembly basically includes a packaging cup and an LED chip mounted on the packaging cup. The traditional packaging cup holder has two internal connection terminals and two external c...
