Detailed Description

As shown in fig. 2 and 3, the utility model discloses a LED assembly 5 is the bar, place in with including the silica gel strip LED and circuit board in the silica gel strip, LED's play plain noodles orientation a big face of silica gel strip, this face are the front of silica gel strip, and the circuit board is close to the back of silica gel strip. Silica gel is used as a carrier of the LED and the circuit board and a packaging material of the LED assembly, so that the LED assembly has flexibility, can adapt to the application occasions of space free curve modeling design, realizes independent 3D sculpture feeling and linear car lamp appearance, cuts into the region which can not be reached by the traditional car lamp, and shows the individuation of car lamp design.

The front side of the silica gel strip is also the light-emitting surface of the LED assembly.

The LEDs are multiple and are arranged at intervals along the length direction of the silica gel strip. Similarly, other components and parts on the circuit board are also arranged along the length direction of the silica gel strip in a dispersing manner, so that heat generated by the LED assembly is dispersed and uniform along the length direction, and a necessary radiator in the traditional signal lamp can be omitted.

The main heating element on the circuit board is arranged behind the circuit board, so that the heat of the circuit board is mainly concentrated on the rear part of the circuit board, and the contact area of the circuit board and the silica gel strip is less, therefore, the influence on the performance of the silica gel strip is less.

The circuit board preferably adopts flexible FR4 circuit board or flexible FPC circuit board, therefore the silica gel strip still can keep fine flexibility even after having integrateed the circuit board, consequently can realize different models through the mode of flexibility, and the model difficulty of LED assembly obviously reduces, need not carry out the arrangement of relevant structure moreover, has also saved the arrangement space of relevant structure.

The components on the circuit board include and are used for control and protection LED's components and parts, consequently no longer need additionally set up independent control module, also need not to consider control module's installation and the problem of generating heat yet.

The LED assembly can be made into strip-shaped structures with various lengths according to requirements. When the LED assembly is used for a signal lamp, only the corresponding LED assembly needs to be matched according to the modeling length, so that the design of the signal lamp is more flexible, and the manufacturing is simpler.

When the LED assembly is manufactured, the LED and the circuit board are fixed firstly, and then the glue sealing is carried out.

The LED assembly is a photoelectric and thermal integrated light source component, when the LED assembly is applied to a lamp, compared with a traditional signal lamp, the LED assembly can reduce the assembly space and the assembly links of a circuit board and a control module, is convenient to assemble and replace, simultaneously reduces the occurrence of insufficient energy collection between the LED and a slender characteristic optical system due to necessary assembly gaps, does not need to independently design the circuit board for each project, and only needs to be matched automatically according to the modeling length of the lamp.

The utility model also discloses a low-cost province space curve form signal lamp, including printing opacity piece 6 with LED assembly 5, the play plain noodles of LED assembly is fixed along with the laminating of shape on the income plain noodles of printing opacity piece. The light-transmitting piece is in a space curve shape, and the length and the width of the light-emitting surface of the LED assembly can be matched with the light-incident surface of the light-transmitting piece. Because the LED assembly can bend towards the front and the back of the silica gel strip, the LED assembly can be freely attached and fixed to the light inlet surface of the light transmitting piece along with the bending trend of the light inlet surface of the light transmitting piece, the situation that energy collection is insufficient due to necessary assembly gaps between the LED and the long and thin characteristic optical system is reduced, the light emitted by the LED assembly can be collected by the light inlet surface of the light transmitting piece in the maximum proportion, and the designed light emitting area between the light transmitting pieces can uniformly emit light.

In order to match the elongated light-transmitting member 6, the LED assembly is also elongated, and the length of the LED assembly used in matching is comparable to the length of the light-emitting characteristic of the light-transmitting member, only a small portion of the LED assembly being shown in fig. 2.

The LED light source is characterized in that a groove can be formed in the light-transmitting piece, and the LED assembly is embedded into the groove to fix the light-transmitting piece.

In the embodiment shown in fig. 3, a U-shaped groove is formed in the light-transmitting member, the bottom surface of the U-shaped groove is the light incident surface of the light-transmitting member, two side walls of the U-shaped groove extend along two long edges of the light incident surface of the light-transmitting member, and the LED assembly is integrally embedded in the groove.

In addition, the fixing mode between the light-transmitting piece and the LED assembly can also be as follows: one of the light-transmitting piece and the LED assembly is provided with a plurality of grooves, and the other one of the light-transmitting piece and the LED assembly is provided with a plurality of protrusions, so that the LED is fixed relative to the light-transmitting piece through one-to-one insertion of the protrusions and the grooves.

The purpose of arranging the radiator in the traditional signal lamp is achieved due to the fact that heat generated by the LED and the circuit board is uniformly dispersed, and therefore the radiator is preferably not arranged in the lamp cavity of the low-cost space-saving curve-shaped signal lamp, and the cost of the signal lamp can be reduced.

The width of the light emitting surface of the LED assembly is preferably made to be consistent with the width of the light emitting characteristic surface of the light incident surface of the light transmitting piece, so that light leakage is avoided, and all emergent rays of the LED assembly are fully utilized.
