Background technology
LED light engine is i.e. comprising LED encapsulation (element) or LED array (module), LED driver and other luminosity, heat The entire combination of, mechanically and electrically element, the combination is directly connected to by an ordinary connector matched with LED lamp On branch circuit.LED light engine is a device between LED lamp and LED, and the technology can effectively improve LED The stability of indoor lamp, improves each performance parameter (such as colour rendering, system light efficiency etc.).
AC LED are for traditional DC LED, to be changed without AC/DC, can directly plug-in in 220V (or 110V) the LED illumination technology that alternating current is used.Traditional LED, it is necessary to which its normal luminous can just be made by providing suitable direct current, Therefore just AC/DC transformers must be added between civil power and LED load could realize DC driven.The application increase of transformer Volume, quality and the cost of whole LED lamp, while certain electricity can be produced in alternating current-direct current conversion process does loss, no The operating efficiency of LED lamp can be given full play to.And AC LED technology development, this problem can be solved.
The key problem in technology of AC LED/light sources is specific arrangement combination technique of the LED grain in encapsulation, while utilizing LED The diode characteristic of PN junction doubles as rectification, and multiple crystal grain are integrated on a single-chip by semiconductor fabrication process, i.e., high Power single crystal grain LED technology, and using staggeredly matrix arrangement technique composition bridge circuit, make AC electric currents can two-way admittance, Realize luminous.
But current AC LED overall powers will produce very big fluctuation, in voltage instability with the change of input voltage Under conditions of fixed, the life-span of lamp bead can be greatly reduced, the luminous efficiency of lamp bead is reduced, illumination effect is poor, and circuit board is exposed, exists Potential safety hazard.
The content of the invention
The invention provides a kind of AC LED light engines, it is intended to solves asking for existing AC LED light engines lighting effects difference Topic.
In order to solve the above technical problems, the present invention is achieved through the following technical solutions：A kind of AC LED light engines, including Sapphire substrate, LED chip, triple channel constant current IC；The triple channel constant current IC is built in sapphire substrate；The LED core Piece is arranged on the preceding surface of sapphire substrate and is connected with triple channel constant current IC；The LED chip is connected by the way of going here and there simultaneously Connect, LED chip is made up of blue chip and red light chips and quantity ratio is 5:1；The rear surface of the sapphire substrate be provided with Power interface connected triple channel constant current IC.
Further, the sapphire substrate is provided with transparent dead ring, the LED chip be arranged on dead ring and Between sapphire substrate；On the one hand circuit board can be prevented exposed, lighting effects on the other hand can be strengthened using transparent material.
Further, in addition to transparent bolt, transparent spring, transparent pad, transparent pad is socketed on transparent bolt, described Transparent spring is socketed on transparent bolt, and transparent spring is located between the head of transparent bolt and transparent pad；The sapphire Substrate, which is provided with neck, the side wall of the pad, is surrounded with ring-shaped groove, and pad is located in neck and passes through ring-shaped groove card It is connected on sapphire substrate；It is easily installed sapphire substrate；Transparent pad can reduce mill of the transparent bolt to sapphire substrate Damage and destroy, in order to avoid the service life and lighting effects of influence sapphire substrate；Transparent spring can reduce transparent bolt to indigo plant The extruding force of jewel substrate, so as to protect sapphire substrate.
Compared with prior art it is an advantage of the invention that：Sapphire substrate is used in the present invention, it is possible to achieve tow sides Give out light；LED chip is using string and mode, it is possible to reduce the quantity of diode, cost-effective；Blue chip and red light chips quantity Than for 5:1, colour rendering index can be improved；Triple channel constant current IC can ensure constant current, prevent overtension, prevent temperature too high.
