Summary of the invention
The technical problem that the present invention mainly solves provides the LED lamp of a kind of lead pitch from weak point, stable performance and saving cost.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of LED lamp, the led chip of the cup that comprise stacker, is fixed in stacker in the end, the electrode pin that goes between and be positioned at the stacker side, led chip is electrically connected with electrode pin by lead-in wire, wherein: the cross section of described electrode pin is stepped, and the zone of electrode pin connection lead-in wire is higher than other zones.
Wherein, the regional electrode pin surface of described connection lead-in wire is positioned at same plane with at the bottom of the described stacker cup.
Wherein, the height of the electrode pin in described connection lead-in wire zone equates with height after led chip is fixed to stacker.
Wherein, the height that connects the electrode pin in lead-in wire zone is higher than the height on plane, place at the bottom of the stacker cup, is lower than the height after led chip is fixed to stacker.
Wherein, comprise described led chip is fixed on primer in the described stacker.
Wherein, the light penetrating object that comprises described led chip of encapsulation and stacker.
Wherein, has silica gel in the described light penetrating object.
Wherein, described stepped electrode pin is formed in one.
The invention has the beneficial effects as follows: because the cross section of described electrode pin is stepped, and the zone that electrode pin connects lead-in wire is higher than other zones, in process of production, can shorten the lead pitch that connects between led chip and the electrode pin from, thereby can reduce the consumption of lead-in wire, save cost; In addition, because lead pitch is from shortening, its operability is good, stable performance and can reduce the probability that short circuit takes place, and enhances productivity.

The specific embodiment
By describing technology contents of the present invention, structural feature in detail, realized purpose and effect, give explanation below in conjunction with embodiment and conjunction with figs. are detailed.
Please refer to Fig. 2 to shown in Figure 4, the invention discloses a kind of LED lamp, the cup that comprise stacker 1, is fixed in stacker 1 in the end 2 led chip 3, lead-in wire 5 and the electrode pin 4 that is positioned at the stacker side, led chip 3 is electrically connected with electrode pin 4 by lead-in wire 5, wherein: the cross section of described electrode pin 4 is stepped, and the zone of electrode pin connection lead-in wire is higher than other zones.
See also shown in Figure 2ly, be the structural representation of LED lamp first embodiment of the present invention.A kind of LED lamp, the cup that comprise stacker 1, is fixed in stacker 1 in the end 2 led chip 3, lead-in wire 5 and the electrode pin 4 that is positioned at the stacker side, led chip 3 is electrically connected with electrode pin 4 by lead-in wire 5, wherein, electrode pin 4 surfaces in described connection lead-in wire zone with 2 be positioned at same plane at the bottom of the described stacker cup.Promptly with the bottom surface A of the stacker 1 on the plane that is parallel to described cup place, the ends 2 during as reference, the height H that connects the electrode pin in lead-in wire zone equates with the height H 1 at glass end.In process of production, can shorten the lead pitch that connects between led chip and the electrode pin from, thereby can reduce the consumption of lead-in wire, save cost; In addition, because lead pitch is from shortening, its operability is good, stable performance and can reduce the probability that short circuit takes place, and enhances productivity.
