Cold cathode decorative lamp and cold cathode fluorescent lamp tube

Abstract

The invention relates to a cold-cathode decorative lamp and cold-cathode fluorescent lamp tube. The lamp tube is an integer glass lamp tube whose glass main body is a cylinder double helix body and each interlock of the glass tube is extended along with the tangential direction of a corresponding helix body. The decorative lamp has a screw, a stylus or snap electric connecting part, wherein the power circuit is fixed on the upper cover and the hollow casing around by the casing; the reflecting cover is fixed on the lower part of the casing or inside the casing; the cold-cathode fluorescent lamp tube is fixed on the casing inside the reflecting cover; the electric connecting part is connected with the input end of the power circuit by wire; the output end of the power circuit is connected with the electrode lead wire of the cold-cathode fluorescent lamp tube; the power circuit can change the mains supply into the high frequency high voltage power.

Description

technical field [0001] The invention relates to a decorative lamp and a fluorescent tube used in the decorative lamp. Background technique [0002] The existing cold-cathode decorative lamps have both lighting and decorative effects. For example, lamps are embedded under the wall cabinet above the combined desk to form hidden local lighting. Commodity display cabinets in commercial buildings and exhibit display cabinets in museums are often equipped with lamps specially illuminated to exhibits to enhance the visibility of exhibits. Gloss, texture, three-dimensional sense, enhance the attractiveness, and enhance the artistic beauty. There is a reflective bowl around the lamp tube of this lamp, and the light is projected forward, so it can be called a decorative lamp, and the embedded decorative lamp can also be called a decorative lamp. For spotlights. The lamp tubes of decorative lamps usually use tungsten-halogen quartz bulbs, so there are a series of problems such as hig...

AI Technical Summary

Problems solved by technology

According to the description of this patent application document, this cold cathode fluorescent spotlight can be used as a decorative lamp, and the lamp tube of this spotlight can be a spiral type. The main body of the lamp tube forms a bending angle of about 90 degrees, that is, the pins are parallel to the axis of the main body of the spiral lamp tube, so the lamp tube of this structure can be called a semi-spiral structure. Spiral lamp tube, there are too many inflection points in the lamp tube of this structure, so that the fluorescent powder cannot be evenly coated on the inner wall of the lamp tube, which brings the problems of complicated processing technology and low yield of the lamp tube. If you want to improve The yield rate needs to increase the diameter of the lamp tube, and because there are too many inflection points in the lamp tube, there are problems such as poor start-up performance of the spotlight during use; it is also mentioned in the patent document that its electrical connector can be connected External power supply, the external power supply is connected to the "driver" in the spotlight, and then the voltage output by the driver lights up the lamp; but the application does not describe the driver, nor does it clarify what kind of power supply the external power supply is, making this It is difficult for ordinary technical personnel in the field to realize
