Problems solved by technology

Moreover, since the luminescent color of the chip itself can only be selected in a certain way, the phosphor powder mixed with it in the transparent colloid is also limited, further limiting the application of LEDs, and it is impossible to achieve a variety of products that meet the needs of different customers.

Abstract

The invention discloses a light emitting diode encapsulation structure and a light emitting diode encapsulation method. The light emitting diode encapsulation structure comprises a light emitting diode lamp bar and a transparent phosphor tube. The light emitting diode lamp bar comprises a first substrate, at least one light emitting diode disposed on the surface of the first substrate and a light emitting face. The transparent phosphor tube comprises a transparent tube body and fluorescent glue sealed in the transparent tube body. The transparent phosphor tube is detachably disposed on one side of the light emitting diode lamp bar to cover the light emitting diodes. Light emitted by the light emitting diodes passes the transparent phosphor tube and irradiates to the outside. By the encapsulation structure, light emitting diode encapsulation is simplified, light emitting uniformity and consistency of the light emitting diode lamp bar are improved, and product diversity is achieved.

Description

technical field [0001] The present invention relates to a packaging structure and a packaging method of a light emitting diode, in particular to a packaging structure and a packaging method of a light emitting diode that can improve product diversity. Background technique [0002] With the further improvement of light-emitting diode (LED) luminous efficiency, its application fields are also further expanded. In addition to being used as a backlight, especially high-power white LEDs, with the gradual increase in cost performance, they will gradually replace traditional lighting sources and become A new generation of green light source. [0003] In order to make the light-emitting diode emit white light for application in the lighting field, phosphor powder is usually added to the packaging material of the light-emitting diode. The phosphor powder absorbs the light emitted by the LED grain and emits light of the second wavelength, and the light emitted by the LED chip and the...
