Background technology
Because light-strip can arrive the object of decorating, and light-strip be luminous softer in the situation that using a small amount of light source, decorative effect is better, at automotive field, has obtained a large amount of utilizations.
But, because light-strip is strip, therefore, when injection moulding, because insufficient pressure causes the material of finally embarking on journey, occur, thereby cause insufficient pressure to cause the problem of Material shrinkage.
Utility model content
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of automobile light-strip that solves the Material shrinkage problem that glue note insufficient pressure causes.
For addressing the above problem, the technical scheme that the utility model adopts is as follows:
An automobile light-strip, comprising: enter light portion; The first light-strip, its bottom is connected with the top of entering light portion, and the first side, light-strip bottom is provided with the first fixed part; The second light-strip, its side, two ends is provided with the second fixed part and the 3rd fixed part, and wherein the second fixed part is near the first light-strip; Transition part, its smooth connection is between the first light-strip and the second light-strip.
Light input part is two groups, first group is entered light portion and second group of top of entering light portion links together, its bottom is the angle of 10-25 °, every group is entered light portion and at least comprises one and enter striation, the bottom of entering striation is provided with for the mounting groove of light source is installed, and light source is along the bearing of trend incident ray that enters striation.
First group is entered light portion and overlaps with the extended line of the first light-strip, and second group is entered light portion and first group of angle that enters light portion is 18-22 °.
Second group is entered light portion and first group of angle that enters light portion is 20 °.
Transition part is the circular arc of radius 35-45mm.
Under optimal cases, arc radius is 40mm.
The radian of circular arc is 70-90 °.
Under optimal cases, the radian of circular arc is 80 °.
Every group is entered light portion and all comprises two and arranged side by side enter striation.
Each bottom of entering striation is provided with reflector, and mounting groove is positioned at the bottom of reflector.
Compared to existing technology, the beneficial effects of the utility model are: due in light-strip, the shape of fixed part and structure are minimum on the light guide effect impact of light-strip, and therefore, fixed part can be all gum-injecting port.Owing to increasing a fixed part at the first light-strip, thereby can from three fixed parts, enter glue simultaneously, efficiently solve into glue insufficient pressure, effectively solve the problem of Material shrinkage simultaneously.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Accompanying drawing explanation
A kind of automobile light-guiding strip structure schematic diagram that Fig. 1 provides for the utility model preferred embodiment;
Fig. 2 enters the partial enlarged drawing of light portion for the automobile light-strip that the utility model preferred embodiment provides.
1, first group is entered light portion; 11, reflector; 12, mounting groove; 2, second group is entered light portion; 3, the first light-strip; 4, the second light-strip; 5, transition part; 6, the first fixed part; 7, the second fixed part; 8, the 3rd fixed part.
The specific embodiment
Below, by reference to the accompanying drawings and the specific embodiment, the utility model is described further:
As depicted in figs. 1 and 2, a kind of automobile light-strip, comprising: enter light portion, it is connected with light source; The first light-strip 3, its bottom is connected with the top of entering light portion, and the first light-strip 3 sides, bottom are provided with the first fixed part 6; The second light-strip 4, its side, two ends is provided with the second fixed part 7 and the 3rd fixed part 8, and wherein the second fixed part 7 is near the first light-strip 3; Transition part 5, its smooth connection is between the first light-strip 3 and the second light-strip 4.
Due in light-strip, the shape of fixed part and structure are minimum on the light guide effect impact of light-strip, and therefore, fixed part can be all gum-injecting port.Simultaneously owing to increasing a fixed part at the first light-strip 3, thereby can from three fixed parts, enter glue simultaneously, efficiently solve into the hypodynamic problem of glue laminated, effectively solve the problem of Material shrinkage simultaneously.Meanwhile, at the first light-strip 3 with enter light portion and increase by the first fixed part 6, make the fixing also more reasonable of whole automobile light-strip.
Entering light portion is two groups, first group is entered light portion 1 and second group of top of entering light portion 2 links together, its bottom is the angle of 10-25 °, every group is entered light portion and at least comprises one and enter striation, the bottom of entering striation is provided with for the mounting groove 12 of light source is installed, and light source is along the bearing of trend incident ray that enters striation.
Owing to entering light portion 1 side first group of routine, set up second group and entered light portion 2, made whole light-strip obtain more light source, strengthened the brightness of light-strip.In addition, between the first light-strip 3 and the second light-strip 4, circular arc transition part 5 is set, makes light be passed to the loss reduction of the second light-strip 4 from the first light-strip 3, thereby reach, make the luminous uniform object of whole light-strip.
First group is entered light portion 1 and overlaps with the extended line of the first light-strip 3, and second group is entered light portion 2 and first group of angle that enters light portion 1 is 18-22 °.Second group is entered light portion 2 and first group of angle that enters light portion 1 is 20 °.
The incidence angle of 20 ° can better be directed into the first light-strip 3 as much as possible by second group of light that enters light portion 2, thus the brightness that effectively improves whole light-strip.
Transition part 5 is the circular arc of radius 35-45mm.Under optimal cases, arc radius is 40mm.The radian of circular arc is 70-90 °.Under optimal cases, the radian of circular arc is 80 °.
The transition part 5 being connected between the first light-strip 3 and the second light-strip 4 is the most severe parts of light loss, if do not handled well, not only can reduce the brightness of light-strip, also can cause the problem of brightness irregularities.Test of many times by inventor proves, at arc radius, is 40mm, and when radian is 80 °, light guide effect is best.
As shown in Figure 2, every group is entered light portion and all comprises two and arranged side by side enter striation.Each bottom of entering striation is provided with reflector 11, and mounting groove 12 is positioned at the bottom of reflector 11.
The design of reflector 11, makes the light that light source is up to enter as far as possible light-strip, rather than scatters to outside, causes waste.
Compared to existing technology, the beneficial effects of the utility model are: due in light-strip, the shape of fixed part and structure are minimum on the light guide effect impact of light-strip, and therefore, fixed part can be all gum-injecting port.Owing to increasing a fixed part at the first light-strip 3, thereby can from three fixed parts, enter glue simultaneously, efficiently solve into glue insufficient pressure, effectively solve the problem of Material shrinkage simultaneously.Meanwhile, at the first light-strip 3 with enter light portion and increase by the first fixed part 6, whole automobile light-strip fixing also more reasonable.
Above-mentioned embodiment is only preferred embodiment of the present utility model; can not limit with this scope of the utility model protection, the variation of any unsubstantiality that those skilled in the art does on basis of the present utility model and replacement all belong to the utility model scope required for protection.
