Embodiment 1

[0036] refer to image 3 , the fluorescent lamp tube of the present invention is improved in the prior art. Take the capillary tube that has been sealed, and first bend the exhaust tube once so that the height B is 5mm, the length A is 20mm, and the angle α is 60°, and then press The normal process is splicing, exhaust, scraping and post-processing. When scraping, the amalgam is positioned at the bent section to make R40, 23W energy-saving lamp tubes. The average initial luminous flux is 1400Lm, the average luminous flux maintenance rate is 83% after 4000 hours, and the service life reaches 10000 hours.

Embodiment 2

[0038] refer to Figure 4 , take the capillary pipe that has been sealed, and bend the exhaust pipe twice into a "Z" shape. The height B of the first bend is 2mm, the length A is 30mm, and the angle α is 90°. The length of the bend is that the length C is 2mm; then connect the fork, exhaust, lower the foot and post-process according to the normal process, and when the foot is lowered, position the amalgam at the second bending section to make R40, 23W energy-saving lamp tubes . The average initial luminous flux is 1350Lm, the average luminous flux maintenance rate is 84% ​​after 4000 hours, and the service life reaches 10000 hours.

Embodiment 3

[0040] refer to Figure 4 , take the capillary that has been sealed, and first bend the exhaust pipe twice into a "Z" shape, where the height B of the first bend is 20mm, the length A is 5mm, and the angle α is 80°, the second bend The length of the bend is that the length C is 25mm; then the fork connection, exhaust, lower legs and post-processing are performed according to the normal process to make R40, 23W energy-saving lamp tubes. The average initial luminous flux is 1380Lm, the average luminous flux maintenance rate is 82% after 4000 hours, and the service life reaches 10000 hours.

Abstract

Present invention relates to a lamp tube with hood lamp and manufacturing method. It contains ducted body and stem, said stem set filament and exhaust pipe, featuring exhaust pipe shaped by bending. Said invented lamp tube with hood lamp can reduce amalgamative working temperature, increasing amalgam fusion temperature and working temperature difference, avoiding amalgam smelting flowing in long time firing. Said invention ensures amalgam being optimum working temperature and optimum mercuric saturated vapor pressure, greatly raising photoelectricity parametric consistency, luminance flux keeping rate and service life with simple operation and low cost in assembling.

Description

technical field [0001] The invention relates to a manufacturing process of a compact fluorescent lamp tube, in particular to a lamp tube with a shade and a manufacturing method thereof. Background technique [0002] In the compact fluorescent tube manufacturing industry, amalgam is mostly used to adjust the saturated mercury vapor pressure in shaded lamps; since the temperature of energy-saving lamp tubes in shaded lamps is relatively high, in order to achieve the best saturated mercury vapor pressure, The selected amalgam is generally BiInHg with higher working temperature. However, at the time of long-life ignition, due to the relatively low melting temperature of BiInHg, the amalgam in the shaded lamp melts and flows, and the saturated mercury vapor pressure changes, resulting in changes in photoelectric parameters, which directly affect the consistency of the lumen maintenance rate; although there are Sometimes the sample can meet the design requirements, but it changes...
