Abstract
An LED lamp free from welding comprises an LED luminous chip and an LED electrode. The LED lamp free from welding is characterized in that the LED electrode is directly arranged on a luminous face steering wheel of the LED luminous chip, a cushion layer is cushioned on the bottom of the luminous face of the LED chip, U-shaped fixing holes are formed in the two ends of the cushion layer, the LED electrode extends to the U-shaped fixing holes, and screw rods penetrate through U-shaped ends of the electrode so that the U-shaped fixing holes can connect the LED electrode and the cushion layer in a fixed and conducting mode. The LED lamp free from welding has the advantages that the LED electrode is directly arranged on the luminous face of the LED chip, a heat conduction insulating pad is used as the cushion layer, and therefore the structure is simplified; the electrode is directly paved on the upper surface of the LED chip and then directly pressed on a radiator through the screw rods and screw fixation force, and therefore heat conduction performance is enhanced; the LED lamp of the structure prevents damage on LED beads caused by high temperature operation and high temperature equipment, and therefore guarantees that the LED lamp is simple in structure and long in service life.
Description
Technical field
The utility model relates to a kind of LED lamp, relates in particular to a kind of LED lamp of welding of not needing.
Technical background
Current market LED lamp generally is welded on circuit by the mode of Reflow Soldering, wave-soldering or electric iron welding, cause LED lamp pearl inevitably to contact high temperature, and encapsulation is all generally also the embedding colloid, easily change under the high-temperature operation environment lamp pearl internal structure displacement and electrical heating welding equipment in varying degrees difficulty or ease stop static and high pressure electric leakage, these situations all to a certain degree affect Product Process quality and the life-span of LED light fixture.
Therefore, need a kind of LED lamp pearl that does not need to weld to avoid welding the above-mentioned drawback of bringing.
The utility model content
In order to overcome above technical problem, the utility model provide a kind of simple in structure, thermal diffusivity good, do not need the LED lamp that welds.
To achieve these goals, the utility model provides a kind of LED lamp that does not need to weld to comprise LED luminescence chip and LED electrode, it is characterized in that: described LED electrode is set directly on the light-emitting area steering wheel of LED chip, the bottom of the light-emitting area of described LED chip is lined with a bedding course, the two ends of described bedding course arrange " U " type fixing hole, described LED electrode extends to " U " type fixing hole, by a lead screw pass electrode, " U " type fixing hole with the LED electrode be connected with bedding course, conducting connects.
Wherein, preferred version is: described bedding course is heat-conducting insulation material.
Wherein, preferred version is: described electrode comprises that also the two ends of " U " type end and described bedding course arrange " U " type fixing hole coupling, and " U " type end that lead screw is passed " U " type end, " U " type fixing hole and the described electrode of electrode fully contacts.
Wherein, preferred version is: an end of described bedding course comprises a unfilled corner, and described unfilled corner is used for the positive and negative level of identification LED electrode and prevents the electrode mistake in assembling.
The utility model has the advantage of:
1, be set directly on the illuminating steering wheel of LED chip by the LED electrode, thereby and simplify the structure by the heat conductive insulating pad is rebasing;
2, by directly electrode being layered on after the LED upper surface by lead screw and screw bed knife direct pressure on radiator, thus the increased thermal conductivity energy;
3, the LED of this structure has solved high-temperature operation, high-temperature service to the damage of LED lamp pearl, thus guaranteed the LED light fixture simple in structure, the life-span is reliable.
Description of drawings
Fig. 1 is a kind of structural representation that does not need the LED lamp that welds of the utility model.
The specific embodiment
Describe the specific embodiment of the present utility model in detail below in conjunction with accompanying drawing.
With reference to figure 1, a kind of LED lamp 10 that does not need to weld of the utility model comprises LED luminescence chip 11 and LED electrode 12, wherein, described LED electrode 12 is set directly on the light-emitting area steering wheel of LED chip 11, simplified the structure of LED lamp, the bottom of the light-emitting area of described LED chip 11 is lined with a bedding course 13, described bedding course 13 is heat-conducting insulation material, the two ends of described bedding course 13 arrange " U " type fixing hole 131, described LED electrode 12 also be arranged to " U " type shape substantially near " U " type fixing hole 131 ends, and described " U " type fixing hole 131 coupling.
Also comprise a lead screw 14, described lead screw is passed electrode 12 " U " type end, " U " type fixing hole 131 is fixedly connected with LED electrode 12 by screw with bedding course 13, like this, not only lead screw 14 can be fixedly connected with LED electrode 12 with bedding course 13, and can pass through lead screw 14 conduction electrodes, i.e. " U " type end of electrode 12 and the direct close contact of lead screw 14.
One end of described bedding course 13 comprises a unfilled corner 132, and described unfilled corner 132 can be identified the both positive and negative polarity of LED electrode 12 and prevent the electrode mistake in assembling.
The utility model has the advantage of:
1, be set directly on the light-emitting area steering wheel of LED chip 11 by LED electrode 12, thereby and simplify the structure by the heat conductive insulating pad is rebasing;
2, by directly electrode being layered on after the LED upper surface by lead screw and screw bed knife direct pressure on radiator, thus the increased thermal conductivity energy.
3, the LED of this structure has solved high-temperature operation, high-temperature service to the damage of LED lamp pearl, thus guaranteed the LED light fixture simple in structure, the life-span is reliable.
The present embodiment is only wherein embodiment not of the present utility model, does not get rid of other distortion according to this embodiment, belongs to the utility model protection domain.
