Abstract
A kind of LED lamp tube with terminal safety insulating device, it comprises LED and relay J 1, one end of one termination LED of power supply and one end of relay J 1 line bag, the other end of another termination LED of power supply and the other end of relay J 1 line bag; Meanwhile, one end of other end contact relay J1 normally opened contact of power supply and the input of former fluorescent lamp start circuit, the other end of the output contact relay J1 normally opened contact of former fluorescent lamp start circuit.The present invention is not before the two ends of LED lamp tube are in place simultaneously, and its relay is for often to open, and power supply two ends disconnect, and its resistance is infinitely great, and noncontact end is not charged, eliminates the potential safety hazard of LED, safe and reliable.
Description
Technical field
The present invention relates to a kind of LED lamp tube, especially directly substitute the LED lamp tube that fluorescent tube is installed, specifically a kind of LED lamp tube with terminal safety insulating device.
Background technology
LED lamp tube is also commonly called as light pipe, fluorescent tube, and its light source adopts LED as luminous element.Traditional fluorescent tube is also known as fluorescent lamp, and respectively there is a filament at lamp two ends, is filled with the argon of trace and thin mercury vapour, tube inner wall scribbles fluorescent material in fluorescent tube, sends ultraviolet, make fluorescent material send visible ray during gas conduction between two filaments.Due to containing heavy metal pollutants " mercury ", make the fluorescent tube scrapped very serious to the pollution of environment.And LED light pipe adopts light-emitting diode as light source, light efficiency is higher, more energy-conservation, longer service life, and more environmental protection.Become the most ideal product that the current stage replaces fluorescent tube.
At present, LED lamp tube and traditional fluorescent lamp are all the same on overall dimensions bore, and LED lamp tube is installed very simple, is taken off by original fluorescent lamp and directly replaces with LED lamp tube, allow 220V electric main directly be added to LED lamp tube two ends during installation.LED lamp tube economize on electricity is up to more than 70%, and the life-span is more than 10 times of common fluorescent tube, is almost non-maintaining, there is not the problem often will changing fluorescent tube, ballast, starter, and the expense of saving of about getting off half a year just can gain cost.The semi-conductor electricity light source of environmental type, light is soft, and color is pure, is conducive to the sight protectio of workman and healthy.
But the existing two end terminals directly substituting the straight pipe type LED lamp tube of fluorescent tube is all can be simultaneously charged, so it also exists potential safety hazard.
Summary of the invention
The object of the invention is all can be simultaneously charged for the existing two end terminals directly substituting the straight pipe type LED lamp tube of fluorescent tube, there is the problem of potential safety hazard, propose a kind of LED lamp tube with terminal safety insulating device.
Technical scheme of the present invention is:
A kind of LED lamp tube with terminal safety insulating device, it is characterized in that it comprises LED and relay J 1, one end of one termination LED of power supply and one end of relay J 1 line bag, the other end of another termination LED of power supply and the other end of relay J 1 line bag; Meanwhile, one end of other end contact relay J1 normally opened contact of power supply and the input of former fluorescent lamp start circuit, the other end of the output contact relay J1 normally opened contact of former fluorescent lamp start circuit.
The line bag of relay J 1 of the present invention and resistance R are connected in series, and are connected in parallel on the two ends of LED.
Beneficial effect of the present invention:
The present invention is not before the two ends of LED lamp tube are in place simultaneously, and its relay is for often to open, and power supply two ends disconnect, and its resistance is infinitely great, and noncontact end is not charged, eliminates the potential safety hazard of LED, safe and reliable.
Accompanying drawing explanation
Fig. 1 is circuit diagram of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the present invention is further illustrated.
As shown in Figure 1, a kind of LED lamp tube with terminal safety insulating device, it comprises LED and relay J 1, one end A1 of power supply connects one end of LED and one end of relay J 1 line bag simultaneously, and the other end A2 of power supply connects the other end of LED and the other end of relay J 1 line bag; Meanwhile, one end of other end A2 contact relay J1 normally opened contact of power supply and the input of former fluorescent lamp start circuit, the other end of output B1, B2 contact relay J1 normally opened contact of former fluorescent lamp start circuit.
The line bag of relay J 1 of the present invention and resistance R are connected in series, and are connected in parallel on the two ends of LED.
Its operation principle is: before LED lamp tube does not have two ends to be in place simultaneously, and its relay is for often to open, and power supply two ends disconnect, and its resistance is infinitely great.After fluorescent tube terminal puts in place, by former fluorescent lamp start circuit, there is a starting current in AC relay coil, impels relay contacts to close, meanwhile, AC relay coil continues to provide LED power because closing of circuit has had freewheel current and normally works.
The part that the present invention does not relate to prior art that maybe can adopt all same as the prior art is realized.
