Abstract

The invention relates to a glass packaging LED bulb comprising a flared glass tube, a strutting piece, an LED wick, a stem assembly and a glass bulb case, wherein the flared glass tube is coated with a power lead, and one end of the power lead reversely extends to pass through the flared glass tube; the strutting piece and an exhaust tube are fixed on the flared glass tube; the LED wick is installed on the strutting piece; the stem assembly is assembled with the flared glass tube, the strutting piece and the LED wick; and the glass bulb case is provided with a neck part which is melted and connected with the flared glass tube of the stem assembly to form a chamber, the LED wick is arranged in the chamber, light-permeable liquid is injected into the chamber, and the LED wick is soaked in the light-permeable liquid. The glass packaging LED bulb has the long-term and reliable sealing effect of glass package, provides the resistance capability of serious environment, such as moisture, dust, corrosive gas, and the like, improves the manufacturing quality and speed of the LED bulb and reduces the production cost of the LED bulb.

Description

technical field [0001] The invention relates to an LED lamp, in particular to a glass-encapsulated LED bulb and a manufacturing method thereof. Background technique [0002] The filament of a traditional incandescent bulb is made of tungsten. It must be in an environment that is isolated from oxygen, such as a medium-to-high vacuum or an inert gas, in order to maintain long-term energization and light. Therefore, the bulb must provide a good sealing effect to maintain the bulb at a medium-high temperature. Only under vacuum or filled with inert gas can the service life of the filament be guaranteed. Due to its environmental protection, durability, low price and excellent sealing effect, glass is used in medium and high vacuum or liquid and gas filled component packaging, such as incandescent light bulbs, fluorescent tubes and vacuum tubes. Although the glass material has the above-mentioned advantages, its high melting temperature and easy thermal processing embrittlement a...
