Description
Technical field
The utility model is related to a kind of light emitting diode, is particularly based on interior connection chip high voltage light emitting diode.
Background technology
The features such as light emitting diode has luminous efficiency height, energy-saving and environmental protection, long lifespan, is referred to as " green illumination light
Source ".High-voltage LED has preferable prospect, and it not only can be applied to traditional outdoor lighting market, glare light electric torch
Market, also progressively permeates, global high-voltage LED city to emerging fields such as automobile headlamp, mobile phone flashlight, ultraviolet LED lamps
Field scale rises year after year, LED general illumination light fixture products is developed using high-voltage LED, overall power consumption can drop significantly
It is low, so that the design requirement to heat-dissipating casing is greatly reduced, it can be seen that high-voltage LED can bring LED illumination lamp
Effective reduction of cost and weight, but its prior meaning is to significantly reduce the design requirement to cooling system, so as to have
Power has cleared away the maximum technology barrier that LED illumination lamp gets in illumination market, and high-voltage LED will be leading following
LED general illumination light fixtures market.
High-voltage LED is according to use requirements such as LED street lamp, LED daylight lamp, LEDbulb lamps, and one kind of exploitation is high
The light emitting diode of die mould（Fig. 1）, mainly comprising support, three LED luminescence chips, gold thread, fluorescent glues, high-voltage LED
It is generally that three chips collocation support carries out assembled in series using integrated encapsulation structure, chip only has 6 light-emitting areas, luminous efficiency
It is low, and current density is uneven.Although it can increase high-voltage LED luminous efficiency by improving chip brightness, but
The cost of LED illumination light source is added, the popularization and application of LED illumination light source are hindered.
The content of the invention
The purpose of this utility model is that there is provided a kind of many light-emitting areas, light efficiency occurred frequently for solution problems of the prior art
Rate, low line loss, low cost based on it is interior connection chip high voltage light emitting diode.
To achieve the above object, the utility model is adopted the following technical scheme that：One kind is lighted based on interior connection chip high voltage
Diode, including support, be assemblied on support LED chip, to LED core plate electrode carry out chip interconnection gold thread, to LED
The fluorescent glue that chip and gold thread are encapsulated, in the LED connection chip connected in wafer level it is integrated, using deep etching
ICP technologies carry out internal insulation to integrated chip, and adjacent LED chip chamber opens up fluted.
It is preferred that, the LED chip is one, realizes in ten light-emitting areas and connects chip high voltage light emitting diode.
It is preferred that, the groove runs through the opposing end surface of chip.
It is preferred that, the cross sectional shape of the groove is inverted trapezoidal.
The utility model has the following advantages that：
1st, simplify packaging technology, reduce cost.
2nd, open up groove and add light-emitting area, improve luminous efficiency.
3rd, line loss is low, and cost is low.
