Abstract

A 4 pi emergent light LED (Light Emitting Diode) light emitting pipe with a chip flipped in a transparent ceramic tube comprises a vacuum seal light transmitting bulb casing and an LED light emitting pipe core which is fixed inside the bulb casing; a light transmitting casing and a core column with an exhaust pipe are sealed together to form into the vacuum seal light transmitting bulb casing; the LED light emitting pipe core comprises a transparent ceramic pipe with a high heat conductivity coefficient and at least a string of LED chips with identical or different light emitting colors; the LED chips are flipped in the external pipe wall of the ceramic pipe; LED chip electrodes are led out of the casing through electrode lead-out lines; at least one light emitting pipe, an LED driver, an electric coupler and the like are formed into an LED illuminating lamp. Compared with the prior art, the 4 pi emergent light LED light emitting pipe with the chip flipped in the transparent ceramic tube and the illuminating lamp have the advantages of being good in heat dissipating, large in LED chip load power, high in output luminous flux, high in light emitting efficiency and the like. The 4 pi emergent light LED light emitting pipe with the chip flipped in the transparent ceramic tube is used for manufacturing the LED light emitting lamp with the output luminous flux from hundreds to 20000 lm and can be used for a discrete light emitting device.

Description

technical field [0001] The invention relates to a 4π light-emitting LED light-emitting tube in an LED lighting lamp and an LED light-emitting device, in particular to a 4π-emitting LED light-emitting tube and an LED lighting lamp in which an LED chip is flip-mounted on a transparent ceramic tube; it is used as a discrete LED light-emitting device and an LED flashlight. Background technique [0002] LED chip flip chip (Flipchip) technology was developed in 1998. It pastes the PN junction of the sapphire GaN LED chip directly on the silicon carrier with a thermal conductivity of 125-150W / m-K, and then uses a high thermal conductivity material for the silicon carrier. Paste on heat sink or heat sink. This flip-chip technology changes the heat conduction and light extraction methods of the traditional front-mount technology. The heat generated by the LEDPN junction of the traditional front-mount technology must pass through the sapphire substrate with a thermal conductivity of...
