[0022] The embodiments provided by this utility model are as follows: Figures 1-4 As shown, an automotive lamp lens includes a base plate 10. A lens bracket 20 is fixedly mounted on the front end of the base plate 10, and a lens 30 is fixedly mounted on the front end of the lens bracket 20.

A first light-emitting LED 50 is fixedly mounted on the top of the base plate 10, and a second light-emitting LED 60 is fixedly mounted on the bottom. The reflector cup 40 is positioned above the first light-emitting LED 50. A placement plate 70 is fixedly mounted on the inner wall of the rear end of the lens bracket 20. A third light-emitting LED 80 is horizontally fixedly mounted on the front end of the placement plate 70. A connecting part 90 is fixedly mounted on the rear end of the base plate 10, and a heat sink 100 is fixedly mounted on the rear end of the connecting part 90. A through air duct 110 is horizontally opened on the connecting part 90, and the two ends of the air duct 110 are respectively connected to the reflector cup 40 and the heat sink 100.
[0023] Lens 30 acts as a beam convergent, efficiently converting over 70% of scattered light into a directional beam, reducing light loss and increasing illumination brightness several times over.
[0024] The light emitted by the first LED 50 is refracted by the reflector 40 to the lens 30, and then emitted through the lens 30. The light emitted by the third LED 80 passes directly through the lens 30 and is emitted outward. The light emitted by the second LED 60 does not pass through the lens 30, but is refracted by the external lampshade and emitted outward.
[0025] The first LED bead 50, the second LED bead 60, and the third LED bead 80 are preferably made of LED chips, which have the advantages of high efficiency and energy saving, ultra-long life, green safety and so on.
[0026] Preferably, the lens 30 covers the front end of the lens holder 20. The lens 30 includes an upper lens 31 and a lower lens 32. Both the upper lens 31 and the lower lens 32 are fixedly mounted on the lens holder 20. The upper lens 31 is positioned directly above the lower lens 32 and the two are fixedly connected. Both the upper lens 31 and the lower lens 32 are arc-shaped structures, and the upper lens 31 protrudes forward relative to the lower lens 32.
[0027] Preferably, a downward-facing heat dissipation fan 120 is fixedly mounted horizontally at the bottom of the substrate 10. The heat dissipation fan 120 is located behind the second light-emitting LED 60. The heat dissipation fan 120 can improve the heat dissipation effect of the substrate 10 and the second light-emitting LED 60.
[0028] Preferably, the base plate 10 has slots 130 on both the left and right sides, and a baffle 140 is horizontally arranged directly below the cooling fan 120. The two ends of the baffle 140 are respectively snapped into the two slots 130. The baffle 140 has several heat dissipation holes 150. The baffle 140 can prevent external wires from directly contacting the cooling fan 120, thus avoiding affecting the rotation of the cooling fan 120 and preventing the cooling fan 120 from damaging the external wires. The heat dissipation holes 150 can ensure air circulation and ensure the heat dissipation effect of the cooling fan 120. The baffle 140 is installed by snapping, which facilitates the installation and replacement of the baffle 140 and improves work efficiency.
[0029] Preferably, the top of the reflector cup 40 is fixedly provided with a plurality of first heat sinks 160, which are vertically arranged along the length of the base plate 10. The two sides of the second light-emitting lamp 60 are symmetrically provided with a plurality of second heat sinks 170, which are fixedly arranged at the bottom of the base plate 10.

[0031] Preferably, the placement plate 70 is in contact with the inner wall surface of the lens bracket 20, and the top of the lens bracket 20 is provided with a plurality of heat dissipation grooves 180. The heat dissipation grooves 180 can improve the heat dissipation efficiency of the third light-emitting lamp 80 and prevent the third light-emitting lamp 80 from being damaged due to excessive temperature.
[0032] Preferably, the lower inner wall surface of the lens holder 20 is an inclined surface that slopes downward along the front end direction, and a through T-shaped groove 190 is horizontally opened on the lower inner wall surface of the lens holder 20. Hot air inside the lens holder 20 flows along the T-shaped groove 190 to the bottom of the base plate 10, thereby improving the heat dissipation efficiency of the device.
