Description
Technical field
The present invention 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.
Summary of the invention
The present invention is for solving prior art in production with in using, also exist and destroy LED illuminator internal structure and be not easily found, produce LED illuminator and reduce the problems such as service life and luminescence be unstable, the LED that a kind of illuminator performance is relatively stable, the life-span is longer is provided.
The technical scheme that the present invention 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, as improvement, 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 further improvement, above and/or under described, conductor comprises the underlying carrier that an insulator is formed, and above and/or under described, conductor is arranged on underlying carrier.
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, described LED light-emitting section is welded on upper and lower conductor.
As improving further as improving further, described lower conductor is ring-type, and the positive and negative electrode conductor of described upper conductor connects and composes ring-type by insulator; The ring that above-mentioned upper conductor is formed is greater than the ring that lower conductor is formed.Ring-type can be annulus or polygon ring.
The present invention compared with prior art; upper and lower conductor fixed support is set and 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 connected on positive and negative electrode conductor separately; i.e. two groups of LED light-emitting section series connection; wherein often organize LED light-emitting section in parallel; 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, extends the LED light-emitting section life-span.
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.
Further, upper and lower conductor connects support LED light-emitting section, thus eliminate the glass column of traditional wick, bulb is avoided to damage because wick rocks in transit, simplify the structure of existing bulb simultaneously, upper and lower conductor support connects the structure of LED light-emitting section, is convenient to automation aborning and mass production.
