Energy-saving lamp with shade and assembly method thereof

Abstract

The invention discloses an energy-saving lamp with a shade and an assembly method thereof. The energy-saving lamp comprises a spiral tube and a glass shade, wherein a 4-10mm high cold end is arranged at the top end of the spiral tube and is provided with mercury source substances for releasing mercury vapor; the top of the cold end is contacted with the bottom of the inner wall of the glass shade; transparent insulation glue is arranged at the bottom of the glass shade; the cold end is positioned in the insulation glue, thus the tube can use the low temperature mercury source substances though working under high temperature and the lighting effect of the energy-saving lamp can be ensured not to be affected, thereby realizing rapid lighting of the energy-saving lamp; and the insulation glue can further prevent influence of conduction of the hot air in the glass shade, thereby better controlling the temperature of the cold end and improving the heat dissipation property of the spiral tube. The assembly method can ensure the cold end at the top of each spiral tube to be effectively contacted with the bottom of the inner wall of the glass shade, without being affected by the dimensional tolerance of the spiral tube and the glass shade.

Description

technical field [0001] The invention relates to an energy-saving lamp and an assembly method thereof, in particular to an energy-saving lamp with a cover and an assembly method of the energy-saving lamp. Background technique [0002] Energy-saving lamps with shades are more and more favored by consumers because their shape and installation method are closer to ordinary incandescent bulbs, and the light color of energy-saving lamps with shades is more uniform and soft. However, when the energy-saving lamp with a cover is working, the lamp tube in the energy-saving lamp with a cover has to face a higher ambient temperature because the glass cover of the energy-saving lamp with a cover blocks the heat diffusion of the inner lamp tube. High temperature amalgam can be used to obtain a suitable mercury vapor pressure to ensure light efficiency. However, after the lamp is ignited, its temperature and mercury vapor pressure will inevitably go through a process of gradually increasi...

Problems solved by technology

However, when the energy-saving lamp with a cover is working, the lamp tube in the energy-saving lamp with a cover has to face a higher ambient temperature because the glass cover of the energy-saving lamp with a cover blocks the heat diffusion of the inner lamp tube. High temperature amalgam can be used to obtain a suitable mercury vapor pressure to ensure light efficiency

However, after the lamp is ignited, its temperature and mercury vapor pressure will inevitably go through a process of gradually increasing and finally tending to be stable. For occasions, the slower climb speed after power on is unacceptable
