Description
Technical field
The utility model relates to a kind of LED, especially a kind of LED using LED light-emitting section.
Background technology
LED light-emitting section is that one pastes upper LED chip (general 1W pastes 28 ~ 31 chips) on the surface of sapphire (or sheet glass), paste the sheet metal of upper " copper is silver-plated " at the two ends of sapphire (or sheet glass) as electrode (wherein cathode metal sheet having aperture) with spun gold welding before every chips simultaneously, its surface last coats silica gel and fluorescent powder again, wherein front is thick, reverse side is thin, so just constitutes LED light-emitting section.The structural representation of LED light-emitting section.
Existing LED light-emitting section one end is connected to and enters on bulb housing negative or positive electrode seal wire, and the other end connects conducting positive and negative electrode between two by the conductor be positioned on bulb glass stem.Due to the welding procedure that LED light-emitting section is special, every root LED light-emitting section needs a negative or positive electrode seal wire entering bulb housing to be connected with it, and many LED light-emitting sections just need the many negative or positive electrode seal wires entering bulb housing to be connected with it like this.Many negative or positive electrode seal wires enter bulb housing, inevitably can produce gap each other, when seal lamps cell-shell, be difficult to accomplish the real gap sealed completely between homopolarity seal wire, the rare heat-conducting gas in bulb can be caused to leak outside, inside and outside intercommunication, thus have influence on the heat dissipation problem of LED light-emitting section, greatly reduce the service life of LED light-emitting section.
Connect the LED light-emitting section of conducting positive and negative electrode between two, be equivalent to LED light-emitting section and directly connect.If as when wherein a LED light-emitting section is in damage or partly damages (this kind of damage is not easily found), namely its resistance variations is larger, the voltage of all LED light-emitting sections on this circuit and electric current are had an impact, make the voltage of the LED light-emitting section on this circuit and electric current produce larger fluctuation, shorten the life-span of LED light-emitting section.
In addition, the glass core bar manufacturing process in order to fixed support LED light-emitting section is complicated, and welding LED light-emitting section, the stop of glass core bar causes it by manual welding, can only be difficult to automation mass production.
In addition, the lamp of existing luminous bar structure, in use and transportation, easily causes wick lamp bar to offset because rocking, or bend from weld, thus affects the use of lamp.
Summary of the invention
The utility model for solve prior art production and use in, existence etc. problem, the LED that a kind of illuminator performance is relatively stable, the life-span is longer, wick is metastable is provided.
The technical scheme that the utility model solves existing issue is: a kind of LED, comprise lamp holder, airtight bulb housing, luminous core, positive pole and the negative pole seal wire of wick is connected through airtight bulb housing, described luminous core comprises the upper of two or more even numbers LED light-emitting section and fixed support LED illuminator, lower conductor, described LED light-emitting section is divided into two groups, described upper conductor comprises and just connects respectively, negative pole seal wire just, cathode conductor, one group of LED light-emitting section one end is connected on positive pole conductor, another group LED light-emitting section one end is connected in cathode conductor, two groups of LED light-emitting section other ends of described decile are connected on lower conductor, as improvement, the support column of a positioning supports lower conductor is provided with in described bulb housing.
As further improvement, described lower conductor is ring-type, and described support column, through the ring heart, locates the lower conductor of ring-type.
As further improvement, described positive and negative electrode seal wire is respectively single wire, and positive and negative electrode seal wire connects positive and negative electrode conductor respectively.
As further improvement, the positive and negative electrode conductor of described upper conductor connects and composes ring-type by insulator.
As further improvement, the ring-type that the positive and negative electrode conductor of described upper conductor is connected and composed by insulator, described lower conductor is ring-type, and the ring that described upper conductor is formed is greater than the ring that lower conductor is formed, and described support column is through the ring heart of upper and lower conductor.
As further improvement, described ring-type can be annulus or polygon ring.
As further improvement, the one or both sides that described support column is positioned at ring are provided with the backstop edge of a locating ring.
The utility model compared with prior art, arrange, lower conductor conductor fixed support also connects two groups of LED light-emitting sections of decile, two groups of LED light-emitting section one end are connected with lower conductor, other end decile is just being connected to separately, in cathode conductor, i.e. two groups of LED light-emitting section series connection, wherein often organize LED light-emitting section in parallel, the support column of a positioning supports lower conductor is provided with in bulb housing, when its beneficial effect is any illuminator resistance difference, the all-in resistance impact of its place group is reduced, avoid the great fluctuation process excessively of every root LED light-emitting section voltage and electric current, every root LED light-emitting section of effective protection, extend the LED light-emitting section life-span, support column can effective supporting and location lower conductor, prevent in transportation, lower conductor Bending Influence light-emitting section.
Further, positive and negative electrode seal wire is connected with the positive and negative electrode conductor of lower conductor, the number of LED light-emitting section quantity no longer has influence on the quantity of positive and negative electrode seal wire, positive and negative electrode seal wire all can be set to single, through airtight glass stem, be conducive to space between maximized reduction glass stem and positive and negative electrode seal wire during fabrication, bulb housing is made to seal wick, inside and outside isolated, prevent gas leakage, extend the life-span of LED light-emitting section.
