Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a lamp shade structure in car light, interior lamp shade 1, LED circuit board 2 and LED lamp pearl 3, interior lamp shade 1 is installed on LED circuit board 2, the surface 11 of interior lamp shade 1 has rhombus decorative pattern 111, the internal surface 12 of interior lamp shade 1 is equipped with nested formula spotlight ware 121, LED lamp pearl 3 is installed on LED circuit board 2, LED lamp pearl 3 is corresponding with spotlight ware 121's central point puts, internal surface 12 through including lamp shade 1 sets up nested formula spotlight ware 121, the thickness of interior lamp shade 1 has still been reduced when guaranteeing high-efficient collection LED light, the requirement of the technology of moulding plastics has been reduced, thereby the cost is reduced, surface 11 through including lamp shade 1 sets up rhombus decorative pattern 111, energy utilization is improved, make the car light satisfy the light intensity value requirement of regulation.

Preferably, the LED lamp beads 3 are low-power lamp beads with power less than 1W, for example, in this embodiment, the power of the LED lamp beads 3 is only 0.7W, although the power is low, the power is matched with the rhombus patterns 111 and the condenser 121, so that the present application can use fewer LED lamp beads 3 to enable the vehicle lamp to have sufficient penetrating power and visibility, and cannot cause too high heat of the vehicle lamp, thereby reducing light attenuation and improving light efficiency.

Specifically, the thickness of the inner lampshade 1 is 4-8mm, and the area of the light emitting surface of the inner lampshade 1 is 5-10cm²The rhombus patterns 111 on the outer surface 11 of the inner lamp shade 1 are distributed in an array, the rhombus patterns 111 are 2-4mm long, 1-3mm wide, 1-3mm in length-width ratio and 0.1-0.3mm in arch height.

Further, the number of the optical concentrators 121 is consistent with the number of the LED lamp beads 3, and the optical concentrators 121 and the LED lamp beads 3 are in one-to-one correspondence, in this embodiment, the number of the optical concentrators 121 and the number of the LED lamp beads 3 are 3, and the LED lamp beads 3 correspond to the central positions of the optical concentrators 121.

Further, in the inner lampshade structure for vehicle lamp according to the present invention, the embodiment of the inner lampshade 1 with diamond patterns is not limited to that shown in fig. 2, for example, the selection of the LEDs is not limited to the use of 3 low-power LEDs of 0.7W, but may also use 4 low-power LEDs of 0.5W, or others.
