Abstract
The invention discloses a built-in power supply type LED (Light-Emitting Diode) fluorescent tube safety power-up switch. The built-in power supply type LED fluorescent tube safety power-up switch is characterized by comprising a shell which is internally provided with two conductive electrodes, wherein an insulating gap is arranged between the two conductive electrodes; the two conductive electrodes and the insulating gap form a cavity; and the cavity is provided with a metal gravity ball which can roll on the cavity to further affect an on/off state of the switch. The built-in power supply type LED fluorescent tube safety power-up switch has the beneficial effects of improved safety and easy installation.
Description
Technical field
The present invention relates to the LED field, particularly a kind of built-in power type LED fluorescent tube adds electric switch safely.
Background technology
What the LED fluorescent tube was different with the fluorescent type fluorescent tube is that the mode of connection of built-in power type LED fluorescent tube is subjected to the strictness restriction of safety certification.Because the driving power of LED fluorescent tube is built-in mode, power supply can not be powered at the two ends from fluorescent tube as the fluorescent type fluorescent tube.If adopt from the mode of lamp tube ends power supply, because LED driving power inside is to adopt for late-class circuit by a bridge rectifier, so, when an end of internally-arranged type fluorescent tube contacts with the electrode of lamp socket, the other end of fluorescent tube will have the alternating voltage of power supply grid, will get an electric shock during the human body contact, this is strict restriction in safety certifications such as UL, for this reason, common processing mode is to take the mode of connection different with the fluorescent type fluorescent tube, that is, can only be from the end power supply of LED fluorescent tube, there is following drawback in this:
1) potential safety hazard of end power supply: the LED fluorescent tube adopts an end power supply mode, may deposit at one end two needle gages from nearer and line short;
2) fluorescent tube is installed inconvenient: owing to be end power supply, the other end is not powered, when fluorescent tube is installed, having 50% chance fluorescent tube runs out of, at this moment just fluorescent tube need be taken off, fluorescent tube horizontally rotates 180 degree and reinstalls, and has increased time and the difficulty of installing;
3) power supply mode with traditional fluorescent type fluorescent tube is different, and people's conducting transmission line is easy to generate mistake when transforming.
Summary of the invention
At the problems referred to above, the object of the invention is to provide a kind of built-in power type LED fluorescent tube safe, easy for installation to add electric switch safely.
For achieving the above object, the technical scheme that the present invention proposes is: a kind of built-in power type LED fluorescent tube adds electric switch safely, it is characterized in that: comprise a housing, be provided with two conductive electrodes in the described housing, be provided with an insulation slit between described two conductive electrodes, described two conductive electrodes, insulation slit form a cavity volume, and being equiped with one on the described cavity volume can roll at cavity volume, and then influences the metal gravity ball of switch on and off.
Further, all be provided with a lead pad on described two conductive electrodes.
Adopt technique scheme, a built-in power type LED fluorescent tube of the present invention adds electric switch safely, and the beneficial effect that has is:
1) security improves: after adopting built-in power type LED fluorescent tube of the present invention to add electric switch safely, the LED fluorescent tube is before being installed on the tube stand, because the equilbrium position of metal gravity ball is not on two conductive electrode slits, the power supply lead wire of two lamp holders of built-in power and fluorescent tube disconnects, so can not occur having improved security greatly because logical powering on the lamp holder is transmitted to the Danger Electric shock risk that the another one lamp holder causes by built-in power; Because two supply lines of power supply separate wiring at support, and the security of power supply has improved, reduced the fire incident that causes because of the aging line short circuit that may cause of electric wire simultaneously.
2) easy for installation: with traditional fluorescent type fluorescent tube to install and use mode identical, LED daylight easier for installation; And after adopting built-in power type LED fluorescent tube of the present invention to add electric switch safely, the installation of LED fluorescent tube does not need to consider the polarity of fluorescent tube, with traditional fluorescent type fluorescent tube to install and use mode identical, just can normally light as long as be installed on the support.

The specific embodiment
Below in conjunction with accompanying drawing the present invention is further explained.
As shown in Figure 1 and Figure 2, a kind of built-in power type LED fluorescent tube adds electric switch safely, comprise a housing 1, be provided with first conductive electrode 2 and second conductive electrode 7 in the described housing 1, first conductive electrode 2 and 7 of second conductive electrodes are provided with an insulation slit 3, described first conductive electrode 2 and second conductive electrode 7, insulation slit 3 form a cavity volume 6, being equiped with one on the described cavity volume 6 can roll at cavity volume 6, and then influence on metal gravity ball 4, the first conductive electrodes 2 of switch on and off and second conductive electrode 7 and all be provided with a lead pad 5.
During concrete the use, the present invention adds electric switch safely and is used for the LED fluorescent tube, before the LED fluorescent tube is installed in the mounting bracket of fluorescent tube, the electric mortiser pin that connects of the power supply of LED fluorescent tube inside and lamp holder is unconnected, have only the LED fluorescent tube of working as to be installed on the tube stand, during horizontal positioned, the power supply on the tube stand just can add electric switch by the safety in the LED fluorescent tube and insert built-in power, is the power supply of LED fluorescent tube.When LED fluorescent tube one termination is gone into support, and an other end is when unsettled, and the connecting line of built-in power disconnects, thereby guarantees operating personnel's safety.Fig. 3 adds the power supply state figure of electric switch safely for built-in power type LED fluorescent tube of the present invention.
Although specifically show and introduced the present invention in conjunction with preferred embodiment; but the those skilled in the art should be understood that; in not breaking away from the spirit and scope of the present invention that appended claims limits; in the form and details the present invention is made a variety of changes, be protection scope of the present invention.
