Description
Technical field
The utility model is related to LED encapsulation process technical fields, refers in particular to a kind of LED patch supports plain conductor
Frame.
Background technology
LED (Light Emitting Diode), light emitting diode is a kind of semiconductor devices of solid-state, and it can be straight
Connect and electricity is converted into light.The heart of LED is a chip for semiconductor, and one end of chip is attached on a support, and one end is negative
Pole, the other end connects the positive pole of power supply, makes whole chip by epoxy encapsulation.Semiconductor wafer is made up of two parts,
A part is P-type semiconductor, and hole is occupied an leading position inside it, and the other end is N type semiconductors, and electronics is mainly in this side.
But when both semiconductors are coupled together, one " P-N knots " is just formed between them.When electric current is acted on by wire
When this chip, electronics will be pushed to P areas, and then electronics will be sent out with hole-recombination in the form of photon in P areas
Go out energy, here it is LED luminous principle.And the wavelength i.e. the color of light of light, it is to be determined by the material for forming P-N junction
's.
Existing LED lamps are usually to be mounted directly on a mounting board, and installing plate is usually laminated structure, including three layers：
For radiate heat dissipating layer, under heat dissipating layer for insulate insulating barrier, under insulating barrier for the line layer that connects up, wherein
Heat dissipating layer is generally aluminium foil or aluminum alloy sheet；Line layer is generally Copper Foil and is made, for doing configuration.LED lamps are arranged on
On heat dissipating layer, welded with line layer.The installing plate heat dispersion of the LED of this type is heavily dependent on insulating barrier
Thermal conductivity index, and the thermal conductivity index of insulating barrier is not often high, causes the heat dispersion of whole LED lamps installing plate band not good.
In actual production and application, it has been found that due between the metal between the first wire, the second wire and thermal wire
Contact point is small, and contact area is small, therefore its rigidity is not enough, and contact position is easily separated from or disconnects.If contact point departs from or disconnects,
The LED lamps at this can be caused to be shorted, now the emission uniformity of whole piece LED light bar is bad, and defect is obvious.
The content of the invention
The technical problems to be solved in the utility model is to provide one kind and can realize SMD processing, and can provide bigger welding
The LED patch support conductive metal frames of contact area.
In order to solve the above-mentioned technical problem, the utility model is adopted the following technical scheme that：
A kind of LED patch supports conductive metal frames, including strip metal body and equi-spaced apart are arranged at strip metal
The location hole of body, it is characterised in that：The strip metal body is provided with multiple spaced injection base units, the note
Penetrating base unit includes being opened in three registration holes and two I-shaped marginal grooves of strip metal body, I-shaped marginal groove position
Between two registration holes.
Preferably, it is provided with connection strap between two I-shaped marginal grooves in the injection base unit.
Preferably, the interior edge of the I-shaped marginal groove is provided with sinking edge.
Preferably, the width at the sinking edge is 0.05mm to 0.07mm.
The beneficial effects of the utility model are：The utility model provides a kind of LED patch supports conductive metal frames,
The utility model uses above-mentioned specific structure design, greatlys save the metal materials of lead frame, and the design of connection strap is improved
The structural stability of conductive metal frames, the design at sinking edge is easy to the injection moulding in the plastic body of LED to process, and reduces
The processing cost of slice type LED, reduces the usage amount of plastic material, and material cost is lower, progressive obvious.
