Between extreme son and second electrode terminal, the insulating base is embedded in the first electrode terminal and the table of the second electrode terminal
On face.
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 equipped with a bowl-shape groove, and the concave surface of the bowl-shape groove is equipped with reflector layer.
Further, it is provided with fluorescent coating in the bowl-shape groove.
Further, card slot is provided with the substrate, the card slot is located at substrate side surfaces.
It can be seen from the above technical scheme that the utility model is in parallel by using at least two small size LED chips
Connection instead of one of tradition large scale LED chip so that ensure LED light shine it is bright under conditions of effectively save chip
Cost, reduces the manufacture production cost of product；Speed of production ratio when LED light 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 carries
The production capacity of high LED light.It is connected in parallel by using at least two small size LED cores so that LED chip occupies the space of LED support
Effectively reduce, make the injection of light more smooth, really effectively so that the lumen of LED light is worth to raising, so that LED
The luminous of lamp more becomes clear.
