Problems solved by technology

[0002] The performance of photoelectric parameters in traditional mercury lamps is determined by the height of the internal resistance block. After the resistance block is added to the exhaust pipe, the exhaust pipe is bent to exhaust. The placement of the resistance block and the processing of the mercury lamp are cumbersome and difficult to control. The product Unstable quality and high production costs
[0003] Existing mercury lamps are exhausted by clamping the exhaust pipe.

Embodiment Construction

[0012] The present invention will be further described below in conjunction with drawings and embodiments.

[0013] figure 1 As shown, a lead-free glass stem for a lamp includes a horn pipe 1 and an exhaust pipe 2, the exhaust pipe 2 and the guide wire 6 are connected in the horn pipe 1, and the exhaust pipe 2 of the first section of the horn pipe is provided with The upper and lower clamping sections 3 and 4 are set up and down on the exhaust pipe 2 in a state of unilateral contraction of the intake and exhaust pipe 2. The shrinking directions of the two clamping sections are opposite to each other. The distance between the clamping sections along the direction of the exhaust pipe is 5 mm, and a spherical block 5 is arranged in the exhaust pipe between the two clamping sections.

Abstract

The invention discloses a lamp lead-free glass stem which comprises a flare tube and an exhaust tube. One portion of the exhaust tube which is sleeved with flare tube is provided with two clamping sections. The two clamping sections are arranged on the exhaust tube in an up-and-down manner and in the state that the two clamping sections are unilaterally retracted into the exhaust tube. The retraction directions of the two clamping sections are opposite. According to the invention, advantages of simple structure, convenient machining and fabrication, low cost, and stable and safe utilization can be realized, the glass stem can be used to effectively prevent mercury from falling into the lamp tube, and at the same time, the overall strength and service life of the exhaust tube are taken into account, so the glass stem is suitable for the production and utilization requirements of mercury lamps of different specifications and performance parameter requirements.

Description

technical field [0001] The invention relates to the field of mercury lamps, in particular to a lead-free glass core column for lamps. Background technique [0002] The performance of photoelectric parameters in traditional mercury lamps is determined by the height of the internal resistance block. After the resistance block is added to the exhaust pipe, the exhaust pipe is bent to exhaust. The placement of the resistance block and the processing of the mercury lamp are cumbersome and difficult to control. The product Unstable quality and high production costs. [0003] Existing mercury lamps are exhausted by clamping the exhaust pipe. In order to ensure that mercury does not fall into the lamp tube during production and use, which affects the parameters of the lamp tube, the shrinkage of the clamped part is large, which affects the overall strength and service life. Contents of the invention [0004] Aiming at the deficiencies in the prior art, the present invention prov...
