Detailed Description
As shown in FIGS. 1, 2 and 3, an automobile taillight with a projection lamp comprises a lamp housing 1, a decorative cover 2, a lamp housing 3, a first objective 4, a second objective 5, a pattern lamp sheet 6, a condenser lens 7, an imaging lens 8, a mirror housing 9, a circuit board 10, a heat dissipation block 11, a projection lamp base plate 12, the projection lamp base plate 12 fixed in the lamp housing 3, the circuit board 10 fixed on the projection lamp base plate 12, the mirror housing 9 fixed on the circuit board 10, the imaging lens 8 and the condenser lens 7 sequentially fixed on the mirror housing 9, the pattern lamp sheet 6 arranged between the imaging lens 8 and the condenser lens 7,
the pattern lamp sheet 6 is fixed on the lamp shell 9 through the first objective lens 4 and the second objective lens 5, the lamp shade 1 is fixed on the lamp shell 3, and the decoration cover 2 is arranged in the lamp shade 1.
The lampshade 1 is an outline carrier of the rear tail lamp and is well matched with a vehicle body sheet metal in appearance; the decoration cover 2 has the overall appearance effect of the rear tail lamp, and the projection lamp is skillfully designed in the decoration cover; the lamp shell 3, the lamp shade 1 and the decorative cover 2 are effectively designed in a matched mode to form space envelope data of the rear tail lamp; the objective lens I4 is an important structural part and is mainly used for fixing the structure of the pattern lamp sheet; the second objective lens 5 is also an important structure and is matched with the first objective lens 4 for use, so that the pattern lamp sheet 6 is positioned and installed.
The pattern lamp sheet 6 is circular in shape. The pattern lamp sheet 6 firstly carries out metal electroplating on a circular glass substrate, and the electroplated substrate is carved with pattern content on a coating by a high-precision laser carving machine; the condenser lens 7 is implemented by a relatively thick convex lens, and an object placed at the focal point of the convex lens forms an inverted enlarged real image, wherein the size of the real image is related to the projection distance, is in direct proportion to the size of the object, and is in inverse proportion to the focal length f. The utility model discloses a two condensing lens realize.
The imaging lens 8 adopts four thin convex lenses to form 1 convex lens group, realizes the imaging function and is used for reducing the distortion generated when a single convex lens is imaged. The distance from the pattern lamp piece to the imaging lens is continuously adjusted according to the convex lens imaging rule, so that the imaging becomes clearer.
The lens shell 9 is mainly used for mounting and fixing the first objective lens 4, the second objective lens 5, the condensing lens 7 and the imaging lens 8.
The circuit board 10 is a target for matching the condensing lens and is used for providing enough light to pass through the pattern lamp sheet.
And the heat dissipation block 11 is used for heat dissipation of the circuit board mechanism and ensuring stable input of light.
The projection lamp base plate 12 is used for mounting and fixing the whole projection structure, and the appearance modeling effect of the whole rear tail lamp is ensured.
The first step is to carry out the overall layout design of the rear tail lamp, and the overall layout design is completed by matching the decorative cover 2 and the lamp shell 3 with the lamp shade 1; and secondly, developing the detailed design of the projection lamp, firstly determining the luminous center R of the LED, secondly determining the focal length and the position of the condensing lens 7, secondly determining the pattern of the pattern lamp sheet 6, and thirdly determining the position of the pattern lamp sheet 6 through the first objective lens 4 and the second objective lens 5. Then, the focal length and the position of the imaging lens 8 are determined, and the imaging lens is fixed through the lens shell 9 to form a projection lamp component. Then, the power of the LED and the size of the heat dissipation block 11 are determined according to the light spot energy diagram, and finally, the LED and the heat dissipation block are fixed on the lamp housing 3 through the projection lamp bottom plate 12.
