Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of low beam narrow modules, and specifically to a low beam narrow module without micro patterns. Background Art
[0002] With the development of the appearance of slender headlights, the narrow module design will inevitably become the mainstream of the headlight shape; in order to conform to this trend, the internal core components - the high and low beam modules will surely develop in the direction of compact structure, few parts, and low energy consumption.
[0003] Traditional low beam modules add micro patterns on the light-emitting surface of the module lens to control the gradient and the NCAP score; this makes the processing of the lens mold complex, with a long processing cycle. Subsequently, it is necessary to continuously polish the micro pattern surface of the lens mold. Each polishing is a shallow polish, and then a sample is sent to the design engineer for light distribution confirmation to see if the gradient is appropriate and if there is sufficient margin, and then it is decided whether to continue polishing. Such a process is time-consuming, laborious, and costly.
[0004] Regarding a low beam module and a high beam module existing in the whole lamp, the traditional low beam module lens has micro patterns, while the high beam module lens does not have micro patterns, which will cause the appearance of the two module lenses to be inconsistent and affect visual aesthetics. To solve the above problems, a low beam narrow module without micro patterns is proposed, and a groove feature structure is designed on the reflector to control the gradient and the NCAP. Summary of the Invention
[0005] The purpose of the present invention is to provide a low beam narrow module without micro patterns to solve the problems raised in the prior art.
[0006] To achieve the above purpose, the present invention provides the following technical solution: The low beam narrow module without micro patterns includes a heat dissipation substrate, a lamp board is installed on the heat dissipation substrate, LED particles are installed on the lamp board, a reflector is installed on the heat dissipation substrate, the reflector is located above the lamp board, a lens is installed at the end of the heat dissipation board, the lens, the reflector, and the heat dissipation substrate are connected by a decorative ring, and a groove is opened at one end of the reflector away from the lens.
[0007] When the headlight is working, the LED particles emit light that passes through the reflector and the cavity between the reflector and the heat dissipation substrate, and finally irradiates the outside through the lens. The traditional process of the low beam narrow module is to add patterns to the lens mold and then polish and grind it later, which has the disadvantages of a long processing cycle, being time-consuming and laborious, and high production cost. The present invention replaces the micro patterns on the lens by opening grooves on the reflector, while achieving the control of the gradient and the NCAP, reducing the processing difficulty of the low beam narrow module and reducing the production cost.
[0008] As a preferred technical solution, the lens has five integrally formed optical surfaces at one end close to the LED particles, and the five optical surfaces correspond to five optical cavities respectively. The three optical cavities in the middle are farther away from the LED particles than the optical cavities on both sides. The three optical cavities in the middle provide a strong light area for the low beam, which can ensure the light intensity of the low beam. The two optical cavities on both sides are used to widen the low beam, ensuring that the low beam can illuminate parts of both sides of the vehicle and provide a field of vision for driving. Reasonable optical cavity design ensures the light intensity of the low beam while providing a certain field of vision on both sides for the driver, ensuring the safety of night driving.
[0009] As a preferred technical solution, the end of the lens away from the LED particles is provided with leather texture, and the two sides of the lens in contact with the decorative ring are provided with side flowers. By providing leather texture and side flowers on the lens, stray light can be effectively eliminated, thereby avoiding the impact of stray light on the driver, reducing driving risks, and further improving the CNCAP score.
[0010] As a preferred technical solution, five reflective bowls are integrally formed on the reflector, the positions of the five reflective bowls correspond one to one with the positions of the five optical cavities, and a cutoff line feature is provided on the side of the reflective bowl that contacts the light board.
[0011] As a preferred technical solution, an avoidance feature is provided at one end of the reflective bowl away from the lens, and the avoidance angle of the avoidance feature is 55 degrees. The setting of the reflective bowl and the avoidance feature can eliminate part of the stray light, further avoid the influence of stray light on the driver, and reduce driving risks.
[0012] As a preferred technical solution, the radiator is provided with a three-zone electroplated surface, which is located in the middle position and corresponds to the corresponding position of the reflective bowl. The three-zone electroplated surface and the reflective bowl cooperate to control the three-zone shape and energy of the overall low beam, so that the low beam can be irradiated out of the lens with a suitable shape and energy, thereby further controlling the CNCAP score.
[0013] As an optimal technical solution, a transverse rib is provided at one end of the reflector close to the lens. The shape of the transverse rib is consistent with the shape of the inner surface of the lens. The width of the transverse rib is 1 mm, and the draft on both sides is 20 degrees. When the light passes from the reflector to the lens, it will pass through the transverse rib. At this time, the transverse rib can cut the edge light type under the low beam, prevent stray light from being emitted from the lens, and make the side light type under the low beam full and uniform.
[0014] As a preferred technical solution, the reflector is provided with a triangular pattern with a width of 1 mm and a height of 0.5 mm. The triangular pattern at the bottom of the reflector is also used to eliminate stray light, further avoiding the impact of stray light on the driver and reducing driving risks.
[0015] As a preferred technical solution, five glue overflow rings are provided on the radiator. A stop block is arranged on one side of the glue overflow ring close to the lens. The stop block is rectangular in shape with a height of 3.3 mm. Four partition plates are designed on the heat dissipation substrate. The four partition plates divide the inside of the heat dissipation substrate into five chambers. The partition plates are used for partitioning. The five divided areas respectively correspond to five optical cavities, ensuring that light can accurately reach the lens from the LED particles, preventing the light patterns in each cavity from mixing, and the stop block can prevent the stray light above the cut-off line from escaping.
[0016] As a preferred technical solution, the directions of the three middle LED particles among the five LED particles are the same as the vehicle driving direction, and the directions of the two LED particles on both sides form a 10-degree angle with the vehicle driving direction.
[0017] Compared with the prior art, the beneficial effects of the present invention are:
[0018] 1. By providing grooves on the reflector instead of the microscopic patterns on the lens, while achieving the control gradient and CNACP, the processing difficulty of the low beam narrow module is reduced, and the production cost is lowered.
[0019] 2. By separating the inside of the reflector with partition plates and providing structures such as leather patterns and side patterns on the lens to reduce the overflow of stray light, the CNACP score is further improved, and the quality of the low beam narrow module is improved.
[0020] 3. By providing five optical cavities and electroplating three-zone surfaces, etc., to improve the fullness and uniformity of the emitted light, the CNACP score is further increased, and the quality of the low beam narrow module is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Embodiment: As Figures 1-6 shown, the present invention provides a technical solution for a low beam narrow module without micro patterns, characterized in that: the low beam narrow module without micro patterns includes a heat dissipation substrate 1, a lamp board 5 is installed on the heat dissipation substrate 1, an LED particle 18 is installed on the lamp board 5, a reflector 4 is installed on the heat dissipation substrate 1, the reflector 4 is located above the lamp board 5, a lens 3 is installed at the end of the heat dissipation substrate 1, and the lens 3, the reflector 4 and the heat dissipation substrate 1 are connected by a decorative ring 2, and a groove 11 is opened at one end of the reflector 4 away from the lens 3.
[0031] When the vehicle lamp is working, the light emitted by the LED particle 18 passes through the reflector 4 and the cavity between the reflector 4 and the heat dissipation substrate 1, and finally irradiates the outside through the lens 3. The traditional process of the low beam narrow module is to add patterns to the mold of the lens 3 and then polish and grind, which has the disadvantages of long processing cycle, time-consuming and laborious, and high production cost. The present invention replaces the micro patterns on the lens 3 by opening a groove 11 on the reflector 4, while realizing the control gradient and NCAP, reducing the processing difficulty of the low beam narrow module and reducing the production cost.
[0032] Five optical surfaces 6 are integrally formed at one end of the lens 3 close to the LED particle 18, and the five optical surfaces 6 respectively correspond to five optical cavities 7. The three optical cavities 7 in the middle position are farther away from the LED particle 18 than the optical cavities 7 on both sides.
[0033] The three optical cavities 7 in the middle position provide a strong light area for the low beam lamp, which can ensure the light intensity of the low beam lamp irradiation. The two optical cavities 7 on both sides are used to broaden the low beam lamp, ensuring that the low beam lamp can irradiate the parts on both sides of the vehicle and providing a field of vision for driving. The reasonable design of the optical cavity 7 can ensure the light intensity of the low beam lamp while providing a certain field of vision on both sides for the driver, ensuring the safety of night driving.
[0034] One end of the lens 3 away from the LED particle 18 is provided with a leather pattern 8, and side patterns 9 are provided on both sides where the lens 3 contacts the trim ring 2.
[0035] By providing the leather pattern 8 and the side patterns 9 on the lens 3, stray light can be effectively eliminated, the influence of stray light on the driver can be avoided, the driving risk can be reduced, and at the same time, the CNCAP score can be further improved.

[0038] The setting of the reflecting bowl 10 and the setting of the avoidance feature 12 can eliminate part of the stray light, further avoid the influence of stray light on the driver, and reduce the driving risk.
[0039] An electroplated three-zone surface 13 is provided on the heat dissipation substrate 1. The electroplated three-zone surface 13 is located in the middle position and corresponds to the corresponding position of the reflecting bowl 10.
[0040] The cooperation between the electroplated three-zone surface 13 and the reflecting bowl 10 is used to control the shape and energy of the overall low beam in three zones, so that the low beam can irradiate out of the lens with a suitable shape and energy, and further control the CNCAP score.
[0041] A horizontal rib 14 is provided at one end of the reflector 4 close to the lens 3. The shape of the horizontal rib 14 is the same as the inner surface shape of the lens 3. The width of the horizontal rib is 1 mm, and the draft angle on both sides is 20 degrees.
[0042] When the light passes through the reflector 4 and shines on the lens 3, it will pass through the horizontal rib 14. At this time, the horizontal rib 14 can cut the lower edge light pattern of the low beam, avoid stray light from emitting from the lens 3, and make the lower side light pattern of the low beam full and uniform.
[0043] Triangular patterns 15 are provided on the reflector 4. The width of the triangular patterns is 1 mm and the height is 0.5 mm.
[0044] The triangular patterns 15 located at the bottom of the reflector 4 are also used to eliminate stray light, further avoid the influence of stray light on the driver, and reduce the driving risk.
[0045] Five glue overflow rings 17 are provided on the heat dissipation substrate 1. A block is provided on one side of the glue overflow ring 17 close to the lens 3. The shape of the block is rectangular and the height is 3.3 mm. Four partitions 16 are installed on the heat dissipation substrate 1, and the four partitions 16 divide the inside of the heat dissipation substrate 1 into five chambers.
[0046] The partition plate 16 is used for partitioning, and the five divided areas respectively correspond to the five optical cavities 7, ensuring that light can accurately reach the lens from the LED particles 18, preventing the light patterns of each cavity from mixing, and the stop block can prevent the stray light above the cut-off line from escaping.
[0047] Among the five LED particles 18, the middle three LED particles are in the same direction as the vehicle driving direction, and the two LED particles 18 on both sides form a 10-degree angle with the vehicle driving direction.
[0048] The working principle of the present invention:
[0049] When the vehicle lamp is working, the light emitted by the LED particles 18 passes through the reflector 4 and the cavity between the reflector 4 and the heat dissipation substrate 1, and finally irradiates the outside through the lens 3. The traditional low beam narrow module process is to add patterns to the mold of the lens 3 and then polish and grind it, which has the disadvantages of long processing cycle, time-consuming and laborious, and high production cost. The present invention replaces the microscopic patterns on the lens 3 by opening grooves 11 on the reflector 4, while realizing the control gradient and CNCAP, reducing the processing difficulty of the low beam narrow module and reducing the production cost.
[0050] The three optical cavities 7 in the middle position provide a strong light area for the low beam, which can ensure the light intensity of the low beam irradiation. The two optical cavities 7 on both sides are used to broaden the low beam, ensuring that the low beam can irradiate the parts on both sides of the vehicle, providing a field of vision for driving. The reasonable design of the optical cavity 7 can ensure the light intensity of the low beam and provide a certain field of vision on both sides for the driver, ensuring the safety of night driving.
[0051] By setting the leather pattern 8 and the side pattern 9 on the lens 3, the stray light can be effectively eliminated, the influence of the stray light on the driver can be avoided, the driving risk can be reduced, and at the same time, the CNCAP score can be further improved.
[0052] The setting of the reflecting bowl 10 and the setting of the avoidance feature 12 can eliminate part of the stray light, further avoid the influence of the stray light on the driver, and reduce the driving risk.
[0053] The cooperation of the electroplated three-zone surface 13 and the reflecting bowl 10 is used to control the shape and energy of the three zones of the overall low beam, so that the low beam can irradiate the lens with a suitable shape and energy, and further control the CNCAP score.
[0054] When the light passes through the reflector 4 and shines on the lens 3, it will pass through the horizontal stop rib 14. At this time, the horizontal stop rib 14 can cut the light pattern of the lower edge of the low beam, avoiding the stray light from emitting from the lens 3, and making the lower side light pattern of the low beam full and uniform.
[0055] The triangular pattern 15 located at the bottom of the reflector 4 is also used to eliminate the stray light, further avoid the influence of the stray light on the driver, and reduce the driving risk.
[0056] The partition plate 16 is used for partitioning, and the five divided regions respectively correspond to the five optical cavities 7, ensuring that the light can accurately reach the lens from the LED particles 18, preventing the light patterns in each cavity from mixing, and the stop block can prevent the stray light above the cutoff line from escaping.
