Embodiment Construction

[0017] The preferred embodiments of the present invention will be described in further detail in conjunction with the accompanying drawings.

[0018] A production process of an electrodeless lamp, the main production process steps include: lamp tube cleaning → lamp tube drying → powder coating on the inner wall of the lamp tube → butt joint sealing → stress relief annealing → exhaust → baking amalgam → testing and inspection.

[0019] In the specific operation link, the crude lamp tube is put into the automatic cleaning machine for half an hour to be washed, and after the cleaning is completed, it is taken out and dried in a dryer at 90-100 degrees to ensure that there are no water droplets left inside and outside the tube.

[0020] In the powder coating step on the inner wall of the lamp tube, the powder slurry needs to be prepared beforehand. The specific operation is to put the cleaned slurry bucket into pure water, and the ratio of the tricolor fluorescent powder to pure wa...

Abstract

The invention mainly discloses a manufacturing technology of an electrodeless lamp. The manufacturing technology comprises the following steps: lamp tube cleaning, lamp tube drying, bepowdering of the inner wall of the lamp tube, seal abutting, stress relieving annealing, exhausting and amalgam baking. The operation is convenient and simple, uniform bepowdering is realized, the connection of the abutting parts is convenient, and the finally obtained products are high in quality and yield.

Description

technical field [0001] The invention relates to the technical field of electrical light sources, in particular to a production process of an electrodeless lamp. Background technique [0002] With the development of technology in light-emitting light sources, currently commonly used light sources are generally in the form of light bulbs, fluorescent tubes, and LED lights. [0003] A filament and an electrode are required in the bulb, and the electrode makes the filament energized, generates heat and emits light to realize the illumination of the light source. However, the filament loss is serious, which seriously restricts the service life of the bulb. [0004] The fluorescent tube mainly includes a fluorescent lamp, a ballast, and a starter. When the switch is closed, the power supply applies a voltage between the two poles of the starter, so that the neon gas in the small neon bulb inside the starter discharges and emits glow. The heat generated by the glow causes the U-s...
