Embodiment 1

[0039] Embodiment 1, 4W spiral lamp tube. It is made of ￠5.3mm potassium-barium lamp tube, the lamp tube length is L 240mm, the input power is 4.1W, the luminous flux is 290Lm, and the luminous effect is ≥70Lm / w

[0040] Other embodiment two, 3W single U (special lamp tube for small table lamps), made of ￠4.7mm thin-walled potassium-barium lamp tube, with a length of L180mm, a luminous flux of 200Lm, and a luminous effect of ≥68Lm / w.

Embodiment 3

[0041] Embodiment 3, ￠45mm glass cover spiral lamp, input power 5.5W, luminous flux 320 Lm, luminous effect ≥ 58Lm / w, can directly replace ordinary incandescent lamps below 40W.

Embodiment 4

[0042] Embodiment 4, MR16 reflective spiral lamp, input power 3.5W, luminous flux 200Lm, luminous efficacy ≥ 57Lm / w.

[0043] Embodiments 1, 2, and 3 are rare because comparable products that can be collected on the market are rare, especially Case 3. It is impossible to install compact energy-saving fluorescent lamps in ￠45mm glass covers before the present invention, so it is impossible to use The effect of the present invention is compared with other similar products one by one. As for Case 4, there are many similar products of reflective compact energy-saving lamps with MR16mm caliber. Here, samples from nearly five or six manufacturers were collected and tested and compared one by one. The results are shown in the table below:

Abstract

A fabrication method of T2 and T1 hot-cathode fluorescent lamps is provided, which comprises processing potassium / barium glass, lead glass or borosilicate glass to a lamp tube, with the outside diameter of the lamp tube being controlled within a range of 1-9 mm; connecting two wires by glass bead fusion sealing to form a core column; winding a tungsten filament to form a spiral filament and then connecting with the wires; coating electronic powder; sealing the lamp tube and exhausting; placing mercury pills or amalgam in the entrance path at one end of the lamp tube, introducing high-purity argon gas (400-1600Pa pressure) into the lamp after exhaust operation, heating the wires by means of induction with a high frequency furnace to heat the mercury pills or amalgam to produce mercury vapors. The invention solves the technical problem of the prior fabrication process of hot-cathode fluorescent lamps rated up to T3 specification, such as large processing difficulty, difficulty in sealing lamp, failure to hermetically connect the core column with the lamp tube, difficulty in controlling processing flame, and complicated exhaust process. The invention provides an ideal technical proposal for the fabrication of hot-cathode tricolor rare earth fluorescent lamps with a tube diameter less than or equal to 7mm.

Description

technical field [0001] The invention relates to the field of electricity, in particular to a light-emitting element, in particular to a low-pressure gas discharge fluorescent lamp, and in particular to a method for manufacturing a T2-T1 specification hot cathode fluorescent lamp. Background technique [0002] Since fluorescent lamps have been commercialized for more than 60 years, the diameter of the lamp tube has become thinner and the luminous efficiency has become higher and higher. Manufacturers are committed to achieving the maximum luminous efficiency with the smallest tube diameter. At present, the tube diameter of fluorescent lamps is between T4 and T5. T=one-eighth of an inch, which is equal to 3.175mm. T4 means four times of one-eighth of an inch, and T5 means five times of one-eighth of an inch. At present, some manufacturers have developed fluorescent lamps with tube diameters of T3 (that is, 3 times the size of an eighth of an inch). However, during the process...
