Helical energy saving lamp tube

Abstract

This invention discloses a spiral energy-saving light tube, which comprises a main body light tube and a top light tube which is connected with the main body light tube into a whole body. The main body light tube is a three-dimensional spiral, and the spiral energy-saving light tube is characterized in that the top light tube is a planar spiral, and the distance from the lowest point of the top light tube to the lower end of the main body light tube is smaller than half of the tube diameter of the light tube; the spiral energy-saving light tube has the advantages that the top light tube is the planar spiral, so that the whole light tube forms a shape of a lamp cover, the lighting dark space at the top part of the light tube is eliminated when the light tube is turned on, and compared withthe illuminating effect of a common bulb, the substitution effect is more ideal; moreover, the distance from the lowest point of the top light tube to the lower end of the main body light tube is smaller than half of the tube diameter of the light tube, so that the height of the whole light tube is shortened, the volume is smaller under identical output power, and the whole light tube seems smaller and brighter.

Description

technical field [0001] The invention relates to an energy-saving lamp tube, in particular to a spiral energy-saving lamp tube. Background technique [0002] With the development of society and the continuous exploitation of the earth's resources, the energy that can be used by people is getting less and less, and energy conservation and environmental protection have become an issue that people need to pay attention to urgently. At present, in people's life, energy-saving lamps have been widely used to replace ordinary light bulbs as lighting sources, and the structure and shape of energy-saving lamps vary according to needs, such as straight tube, round, U-shaped, and spiral. As for the common three-dimensional spiral energy-saving lamp tube, it is composed of a three-dimensional spiral main lamp tube and a straight top lamp tube connected integrally. Since most of the area in the middle of the top is empty, when the lamp tube emits light, There is a dark area in the middle...

Problems solved by technology

As for the common three-dimensional spiral energy-saving lamp tube, it is composed of a three-dimensional spiral main lamp tube and an integrally connected straight top lamp tube. Since most of the area in the middle of the top is empty, when the lamp tube emits light, There is a dark area in the middle part of the top of the lamp tube, which is different from the lighting effect of ordinary bulbs, and the replacement effect is not very ideal
