Background technology
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 mode, so, when an end of internally-arranged type LED 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, the 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
Because be end power supply, the other end is not powered, when fluorescent tube is installed, have 50% chance fluorescent tube electricity in short supply, at this moment just fluorescent tube need be taken off, fluorescent tube horizontally rotates 180 degree and reinstalls, and has increased the time and the difficulty of installing.
3, the 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
The utility model mainly is to solve the existing in prior technology deficiency, thereby develops a kind of built-in power type LED fluorescent tube safety lamp holder of safe ready.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of built-in power type LED fluorescent tube safety lamp holder, it is characterized in that: have circular shell, before described housing is divided into by dividing plate, back two parts, the front is closed cavity, the back is to be used for uncovered (opening) structure of combining with the fluorescent tube lamp body, the front end face of described closed cavity is equipped with a pair of lamp holder contact pin, cavity middle (interior) is provided with the position sensor unit (external diameter of position sensor unit is slightly less than the housing internal diameter) with the loose fit of housing internal diameter, described position sensor unit is an insulating materials, be equipped with between described position sensor unit and the front end face and be exposed to the outer also position sensing ball of tool retraction function of front end face, between position sensor unit and the dividing plate stage clip is housed, be respectively equipped with executing electric contact and being subjected to electric contact of mutual correspondence on described position sensor unit and the dividing plate, described lamp holder contact pin with execute electric contact and be electrically connected.
The technical solution of the utility model can also be further perfect:
As preferably, described position sensing ball is fixed on the position sensor unit center, and the center of described front end face has the circular hole that is slightly less than the position sensing bulb diameter.
As preferably, be provided with at the back side of executing electric contact two be electrically connected with it execute the electrical lead electrode, a pair of lamp holder contact pin is electrically connected with the adjacent electrical lead electrode of executing by executing electrical lead; Be provided with at the back side that is subjected to electric contact be electrically connected with it be subjected to the electrical lead electrode, be subjected to electrical lead being subjected to be connected with on the electrical lead electrode.
As preferably, described housing comprises plastic casing and aluminum enclosure, and described aluminum enclosure is linked in the plastic casing outside of dividing plate previous section, and described plastic casing front end face is uncovered structure.
As preferably, described stage clip is connected on the dividing plate by hold-down screw.
As preferably, describedly execute the electrical lead electrode and execute electric contact and be fixed on the position sensor cell by the electrode fixing rivet.
As preferably, describedly be subjected to electric contact and be fixed on the dividing plate by the electrode fixing rivet by the electrical lead electrode.
As preferably, described position sensing ball is fixed in the position sensor unit by position sensing ball hold-down screw.
With novel beneficial effect be:
Adopt built-in power type LED fluorescent tube safety lamp holder of the present utility model, can show obvious superiority in the following aspects:
1. security improves
Because the LED fluorescent tube is before being installed on the tube stand, two lamp holders of built-in power and fluorescent tube, perhaps one of them lamp holder disconnects, so can not occur having improved security greatly because of 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.
With traditional fluorescent type fluorescent tube to install and use mode identical, LED daylight easier for installation.
After adopting built-in power type LED fluorescent tube safety lamp holder of the present utility model, 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.
3. because two supply lines of power supply separate wiring on support, 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.
