Description
Technical field
The utility model relates to semiconductor light emitting field, particularly relates to a kind of fluorescence LED lamp.
Background technology
The wafer that the core of light-emitting diode is made up of p-type semiconductor and n-type semiconductor, has a transition zone, is called p-n junction between p-type semiconductor and n-type semiconductor.In the PN junction of some semi-conducting material, the minority carrier of injection and majority carrier compound tense can discharge unnecessary energy in the form of light, thus electric energy is directly converted to luminous energy.PN junction adds reverse voltage, and minority carrier is difficult to inject, therefore not luminous.This diode utilizing injection electroluminescence principle to make, light-emitting diode, is generally called light emitting diode (LED).
It is inexorable trend that LED replaces general lighting lamp, but LED still comes with some shortcomings at present, reduces LED thermal radiation and manufacturing cost further, is the matter of utmost importance that acceleration LED is applied.
Utility model content
Technical problem to be solved in the utility model is to provide that a kind of structure is simple, with low cost, low in energy consumption, radiationless, energy-saving and environmental protection, fluorescence LED lamp that light color is adjustable.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of fluorescence LED lamp, comprise the symmetrical pedestal of stairstepping, the symmetrical pedestal of described stairstepping is respectively arranged with pin, heat-sink shell is provided with between the symmetrical pedestal of stairstepping, LED chip is provided with on described heat-sink shell, described LED chip two ends are provided with metal contact wires, described metal contact wires is connected with the symmetrical pedestal of stairstepping, described LED chip is provided with phosphor powder layer, be provided with packed layer on described phosphor powder layer, on described packed layer, be provided with plastic lens.
Described pin is connected with the symmetrical pedestal of stairstepping, the symmetrical pedestal of described stairstepping is connected with metal contact wires, described metal contact wires is connected with LED chip, for the conducting of LED chip, described LED chip to coordinate with phosphor powder layer according to the change of size of current can send different colours light, described plastic lens is used for the scattering of LED lamplight, makes the light of LED illumination more even, soft.
On the basis of technique scheme, the utility model can also do following improvement.
Further, described heat-sink shell is insulation material layer, and for isolation, the insulation of the symmetrical pedestal of stairstepping, and insulation material layer plasticity is effective, and encapsulation is more prone to.
Further, described packed layer material is thermal radiation absorption material, and thermal-radiating absorption in using for LED, prevents thermal radiation from polluting.
Further, described metal contact wires is a kind of in copper, aluminum metal connecting line, and wherein preferably copper metal contact wires, because copper metallic conductivity is strong, resistivity is low, effectively can reduce the thermal effect in LED use procedure, but the utility model is not limited to this.
The beneficial effects of the utility model are: simple, the easy encapsulation of structure, cheap for manufacturing cost, low in energy consumption, good energy-conserving effect, have better application prospect.
