Problems solved by technology

[0003] The invention provides a new type of lamp tube with a shade, which not only overcomes the inherent defect that the amalgam in the existing lamp with a shade is easy to flow, but also solves the difficulties in the production of the lamp tube (capillary tube) and the assembly of the whole lamp, and improves the production efficiency of the lamp. Consistency with shaded lights reduces production costs

Embodiment 1

[0010] Embodiment 1, a lamp tube with a cover lamp, comprising a tube body 1 and a stem 2, the stem 2 is provided with a filament 3 and an exhaust pipe 4, and an amalgam 5 is housed in the exhaust pipe 4, so The above-mentioned exhaust pipe 4 has partly flattened 6, and the amalgam 5 is located in the exhaust pipe above the flattened 6. The length is 3-10mm.

Embodiment 2

[0011] Embodiment 2, manufacture the above-mentioned lamp tube with cover lamp, take the tube body that has been sealed, connect the foot to inject mercury, exhaust, seal off, seal off, and then insert the lamp tube exhaust pipe downward into a 200-400 degree Celsius Heat in the oven until the amalgam and the glass at the top of the exhaust pipe are completely melted, vibrate the pipe body to make the amalgam and the glass at the top of the exhaust pipe dense, remove it from the oven and let it cool naturally. Burn flat.

Embodiment 3

[0012] Example 3: To manufacture the above-mentioned lamp tube with cover lamp, clamp the exhaust pipe of the core column with a machine part, seal the tube body of the core column, exhaust and inject mercury, then seal off, and then exhaust the lamp tube The tube is inserted downward into an oven at 200-400 degrees Celsius and heated until the amalgam and the top glass of the exhaust pipe are completely melted, and finally the tube is vibrated until the amalgam and the glass on the top of the exhaust pipe are dense, and then removed from the oven to cool naturally.

[0013] The performance comparison table of the lamp tube made according to the methods of Examples 2 and 3 and the lamp tube made by the conventional method is as follows. In order to ensure the uniformity and comparability of the test data, the number of samples in each group of statistical experiments is 50, the specifications of the lamp tubes are all uniform, the power is 14W, the color temperature is 2700K, a...

Abstract

The invention discloses a lamp tube for a lamp with a cover, and relates to the field of lighting. The lamp tube for the lamp with the cover comprises a tube body and a core column, wherein the core column is provided with a filament and an exhaust pipe; the exhaust pipe is filled with amalgam; part of the exhaust pipe is flattened; the amalgam is positioned in the exhaust pipe above the flattened part so as to ensure the consistency of a working temperature of the amalgam, and avoid amalgam position change caused by melt flow of the amalgam which is lighted for a long time; therefore, the amalgam can be at the optimum working temperature; the saturated vapor pressure of mercury is optimal; and the consistency of photoelectric parameters are improved greatly, which extremely contributes to improving lumen maintenance of an overall lamp and prolonging the service life of the lamp. The invention also discloses a manufacturing method for the lamp tube of the lamp.

Description

technical field [0001] The invention relates to the lighting field, in particular to a lamp tube with a cover lamp. Background technique [0002] In the manufacture of compact fluorescent lamp tubes with shades, amalgam is mostly used at present to adjust the saturated mercury vapor pressure in the shaded tubes. The lamp with cover has good sealing performance, and the temperature of the lamp tube is relatively high. In order to make the saturated mercury vapor pressure reach the optimum value, it is necessary to choose a high-temperature amalgam with a relatively high working temperature. However, the melting point of high-temperature amalgam is relatively low, and it is easy to melt and flow, resulting in changes in the working position of the amalgam, resulting in changes in photoelectric parameters and affecting the consistency of the shaded lamp. In order to solve this problem, it is useful to lengthen the exhaust pipe to reduce the working temperature of the amalgam, ...
