Specific embodiment
Refer to shown in Fig. 1 to Fig. 6, that show the concrete structure of the first embodiment of the present invention, be a kind of pair of cup
Adjustable color temperature, aobvious finger and seven color adjustable LED lamps, which can arbitrarily adjust out R, G, B, W multicolour, and by this several primary colours
Tune is mixed to form adjustable color temperature, the aobvious seven glory lines for referring to, for decorating, builds different artistic conceptions.The structure of this kind of LED includes
There is 10, four groups of the insulating body LED wafer 31,32,33,34, fluorescent material glue-line 41 of conducting terminal 21,22,23,24, four and thoroughly
Gelatin layer 42.
Wherein, the insulating body 10 is made with plastic material, sees Fig. 3, and the profile of the insulating body 10 is square,
The ratio on its two side of length and width is A1: A2=1:1.The recessed center for having a cup, the cup of the top surface of the insulating body 10 sets
There is a nontransparent withe 11, cup is divided into two to form the first reflector 12 and the second reflector 13.The fluorescence
, in the first reflector 12,42 injecting glue of substratum transparent is in the second reflector 13 for 41 injecting glue of arogel layer.Nationality is by withe 11
Design cause two reflectors 12,13 fluorescent material glue-line 41 and substratum transparent 42 it is mutually isolated, will not mix, can
To prevent photochromic intersection and pollution.
In the present embodiment, the withe 11 is integral type structure with insulating body 10, is gone out such that it is able to one-shot forming, nothing
Need assembling.First, second reflector 12,13 is square and size dimension is identical, and first, second reflector 12,13 is equal
Be square structure, its Aspect Ratio be W1: W2=1.6：1；It is of the same size rectangular by two reflectors 12,13 are fabricated to
Shape, so as to two reflectors are symmetrical so that light shape is symmetrical, beneficial to obtaining more preferable light mixing effect outside cup.
In the embodiment, Fig. 5 is seen, the depth of the first reflector 12 of the insulating body 10 is H1, and described second is reflective
The depth of cup 13 is H2, and the height of the withe 11 is H3, wherein, H1=H2, H3< H1.Nationality by it is this by the longitudinal direction every
The ratio that the height of wall 11 is arranged is relatively low, therefore, the first and second reflectors 12,13 can more easily from the top of withe 11
4 position of height difference H carry out mixed light.
Additionally, edge is equipped with concave station 14, the fluorescent material in the rim of a cup of first reflector 12 and the second reflector 13
Base face of the top surface of glue-line 41 and substratum transparent 42 parallel to the concave station 14.On the one hand tradition can be avoided without the reflective of concave station
Cup, after injection fluorescent material glue-line, the week of colloid causes the surface irregularity of fluorescent material glue-line along climbing, and affects light efficiency
Really；On the other hand, after the concave station 14 may insure molding blanking, the rim of a cup of reflector 12,13 will not be unedged；The third aspect,
Concave station 14 also causes the area increase of reflector 12,13 rims of a cup, so as to the light mixing effect of two reflectors is more preferable.
Four groups of conducting terminals are first group of conducting terminal, 21, second group of conducting terminal 22, the 3rd group of conducting end respectively
Sub 23, the 4th group of conducting terminal 24.Each group conducting terminal be arranged in order and with the 10 one produced by insert molding of insulating body
（MOLDING）.First to fourth group of conducting terminal 21,22,23,24 is respectively provided with a positive terminal and a negative terminal, respectively
Positive and negative electrode terminal is distributed in the opposite sides of insulating body 10；Each positive and negative electrode terminal be respectively provided with die bond portion 211,212,221,
222nd, 231,232,241,242 and leg portion 213,214,223,224,233,234,243,244；Every group of conducting terminal each
Leg portion does not stretch out 10 both sides of insulating body the curved bottom surface for being accommodated in insulating body 10 of opisthotonos.
Wherein first, second group conducting terminal 21,22 has die bond portion 211,212；221st, 222 expose the first reflector 12
Bottom surface, the 3rd, the 4th group of conducting terminal 23,24 have die bond portion 231,232；241st, 242 expose the bottom of the second reflector 13
Face.The die bond portion 211,212 of the first, the 4th group of conducting terminal 21,24；241st, 242 away from withe 11, and this second,
The die bond portion 221,222 of three groups of conducting terminals 22,23；231st, 232 near withe 11, is the LED wafer peace of different color
Dress is prepared.
Four LED wafers include that red-light LED chip 31, the first blue LED wafers 32, the second blue-ray LED are brilliant respectively
Piece 33 and green light LED chip 34.The red-light LED chip 31 is fixed on the die bond portion 211 of first group of conducting terminal 21, and this is first blue
Light LED wafer 32 is fixed on the die bond portion 222 of second group of conducting terminal 22, and second blue LED wafers 33 are fixed on the 3rd group
The die bond portion 242 of the 4th group of conducting terminal 24 is fixed in the die bond portion 231 of conducting terminal 23, the green light LED chip 34 so that red
Light LED wafer 31 is intercepted to light with nontransparent withe 11 by centre away from green light LED chip 34, so as to
Prevent photochromic intersection and pollution.Fluorescent material glue-line 41 is injected into the first reflector 12 again, it is blue by the red-light LED chip 31 and first
Light LED wafer 32 can blend a kind of white light through fluorescent material glue-line 41.And substratum transparent 42 is injected into the second reflector 13
In, second blue LED wafers 33 and green light LED chip 34 penetrate substratum transparent 42 and send blue and green light two color light, when two
Light in reflector 12,13 mixes outside cup, and when being adjusted by controller, with realize adjustable color, it is aobvious refer to it is adjustable, seven color
Adjustable effect, is particularly suitable for use as light decoration, to build different artistic conceptions.
Additionally, the length in the die bond portion 211,231 of the positive terminal of the first, the 3rd group of conducting terminal 21,23 is more than which
Length L1 in the die bond portion 212,232 of negative terminal>L1 ', L3> L3′；Second, the 4th group of conducting terminal 22,24 it is negative
Length L2 ' of the length in the die bond portion 222,242 of extreme son more than the die bond portion 221,241 of its positive terminal>L2, L4 '>
L4.Each LED wafer 31,32,33,34 is fixed in the larger die bond portion 211,222,231,242 of length, on the one hand can have compared with
