Utility model content

In view of the foregoing, the utility model be provided to solve the deficiencies in the prior art a kind of production cost it is low, Production capacity is high, can improve the multi-chip tandem backlight LED of LED lumen value.

To reach above-mentioned purpose, technical scheme is used by the utility model solves its technical problem：

A kind of multi-chip tandem backlight LED, including substrate, in addition to first electrode terminal, insulating base, second electrode end Son and at least two LED chips, the first electrode terminal are disposed adjacent with second electrode terminal on substrate, and described first Filled up and separated by the substrate between electrode terminal and second electrode terminal, adjacent two LED chip is connected in series and turns on connection Between first electrode terminal and second electrode terminal, the insulating base is embedded in the first electrode terminal and the second electrode On the surface of terminal.

Further, the first electrode terminal and second electrode terminal have one end to extend out to outside insulating base.

Further, the second electrode terminal has some primers, each LED core close to the end set of first electrode terminal Piece is bonded on second electrode terminal by matching primer.

Further, the second electrode terminal accounts for area >=60% of insulating base bottom, the interval between the LED chip Distance is 0.1 ㎜ -2 ㎜.

Further, the insulating base is provided with a bowl-shape groove, and the concave surface of the bowl-shape groove is provided with reflector layer.

Further, it is provided with fluorescent coating in the bowl-shape groove.

Further, connected between adjacent two LED chip using gold thread, a diameter of 10 μm -50 μm of gold thread.

Further, neck is provided with the substrate, the neck is located at substrate side surfaces.

It can be seen from the above technical scheme that the utility model is connected by using at least two small size LED chips Connection instead of one of tradition large scale LED chip so that the effectively save chip under conditions of guarantee LED lights and become clear Cost, reduce the manufacture production cost of product；Speed of production ratio when LED is manufactured using small size LED chip uses big The speed of production of size LED chips is fast, can effectively improve the production efficiency of product, the consuming reduced work hours, fundamentally carry The production capacity of high LED.It is connected in series by using at least two small size LED chips so that LED chip occupies the sky of LED support Between effectively reduce, make the injection of light more smooth, really effectively cause LED lumen be worth to raising so that The luminous of LED more becomes clear.
