Embodiment Construction

[0009] The present invention will be described in detail below in conjunction with specific embodiments and accompanying drawings.

[0010] Such as figure 1 As shown, a DC-driven CCFL lamp tube includes a lamp cap 5, a lampshade 1, and a CCFL luminous tube 4. A small control box 3 is provided at one end of the CCFL luminous tube, and a small inverter is arranged inside the control box 3. The inverter is connected in series with the CCFL luminous tube 4 . It can be used by the luminous tube with inverter and the general DC power supply of the lamp holder, which can easily pass the audit of safety regulations. The inverter is designed inside the lamp tube, which makes the structure and assembly of the lamp more convenient and convenient. It is safer to completely hide the part of the high-voltage line in the lamp tube, and at the same time solve the doubts about high-voltage lighting of CCFL lamps.

Abstract

The invention discloses a direct current drive CCFL lamp tube. The direct current drive CCFL lamp tube comprises lamp holders, a lampshade and CCFL luminous tubes. A small control box is arranged at one end of each CCFL luminous tube. A small inverter is arranged in each control box and connected with the corresponding CCFL luminous tube in series. The CCFL luminous tubes are double-U-shaped straight tubes. Each of the CCFL luminous tubes is connected with a corresponding power supply. Compared with the prior art, the direct current drive CCFL lamp tube has the beneficial effects of being safer, more convenient and faster to use, lower in failure rate and longer in service life. Direct current power supplies can be bought everywhere, so that the popularization rate is higher.

Description

technical field [0001] The invention relates to the field of lighting fixtures, in particular to a DC-driven CCFL lamp tube. Background technique [0002] At present, the general CCFL lamps on the market are driven by AC. For places that need to use mobile power, such as mobile vendors, mobile car vendors, field camping lights, etc., the high-voltage lines of AC-driven CCFL lamps are easy to use during the movement. Risk of electric shock. It is an urgent technical problem to develop a safe and convenient CCFL lamp using DC low-voltage power supply. Contents of the invention [0003] Aiming at solving the above-mentioned background problems, the present invention provides a DC-driven CCFL lamp tube, which solves the high-voltage dangerous problem of CCFL lamp tubes driven by AC power, and at the same time is convenient for mobile use, and the supporting DC power supply does not need additional configuration. 12V, 24V batteries can be used. [0004] The technical solutio...
