Description
[technical field]
The utility model relates to lighting field, refers in particular to a kind of LED fluorescent lamp and module thereof.
[background technology]
Along with the LED broad application, the technology of LED daylight is day by day ripe, and begins to drop into commercial the use, will get later on to replace traditional fluorescent tube gradually.Variation has taken place with respect to fluorescent tube power supply the principle in the past in existing LED fluorescent-lamp tube; Two electrodes of fluorescent tube end cap in the past are respectively live wire and zero line; Two conducting terminals of the present same end of fluorescent tube are same electrode; Can start to exchange fire line or zero line, the two ends of whole fluorescent tube are divided into the live wire and the zero line of civil power, and this is and the difference of fluorescent lamp in the past.
If we forget powered-down when mounted; In the two ends of fluorescent tube, wherein an end must be live wire at this moment, if the end that we insert earlier when mounted is a live wire; The voltage of civil power or can be carried in through internal circuit on the electrode of an other end of fluorescent tube then; If this moment, we ran into hand or other positions of health the electrode of this end accidentally, then line voltage can be added on our health, and gently then health has the paralysis sense; Heavy then can receive electric injury, therefore, the LED fluorescent tube has great potential safety hazard when being installed.
Electric shock hidden danger in the LED fluorescent tube installation process, the second half year in 2009, world security certification authority such as UL and MET required: go into live wire (L) in a termination of LED fluorescent lamp, touch the other end with hand, the danger of electric shock can not be arranged.This makes LED fluorescent tube industry face the situation that designs lamp tube structure again; Begin to have engendered the fluorescent tube structure of many protection against electric shocks subsequently: number be the Chinese utility model patent of CN201437921U like patent announcement; This patent discloses a kind of safe fluorescent tube; Its technical scheme is through reducing the probability that touches conducting terminal when people install at end cap and conducting terminal outsourcing insulating layer coating, can reduce the Danger Electric shock risk that the short-circuit of terminals causes simultaneously, all can having electric current to pass through but fluorescent tube remains two ends; The termination of conducting terminal remains and leaks outside; This scheme does not fundamentally solve the hidden danger of getting an electric shock, and just reduced the probability of artificial electric shock relatively, so the technical scheme of this patent does not still have thoroughly to solve the potential safety hazard that fluorescent tube gets an electric shock.
Other has a patent announcement number to be: the Chinese utility model patent of CN201425280Y discloses a kind of LED fluorescent tube anti-electric shock apparatus, this patent in the end cap of the two ends of LED fluorescent tube, built-in a kind of switching device; Utilize circuit contact to break off and combine end cap lamp base and inner being electrically connected; This utility model patent utilization machinery or electronic switch are controlled the end cap lamp base and are connected with inner electrical equipment, have eliminated the potential safety hazard when installing, and have ensured the safety when changing fluorescent tube.
Though this mode has been avoided the danger of getting an electric shock, and in installing and using, has brought inconvenience:
The one, bigger to the structural change of lamp tube ends, increased the mould design cost;
The 2nd, whether must be noted that electronic switch closes when installing;
The 3rd, still there is the hidden danger of electric leakage in electronic switch;
The 4th, too big with the gap of conventional mounting, do not meet people for a long time to the understanding of fluorescent lamp.
Therefore, people are badly in need of that a kind of design cost is cheap, easy to install, the circuit energy consumption is low and can be thoroughly eliminated the LED fluorescent tube of electric shock hidden danger.
