Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of vehicle lamps, and in particular to a low beam three-zone vehicle lamp module system and a vehicle lamp. Background Art
[0002] The low beam in car lights is a function used for lighting at night or in dimly lit places. It is the main determinant to ensure the safe lighting of the car during driving. The low beam is a function required by mandatory regulations. Therefore, the regulations have set requirements and limits on the distribution and brightness of the low beam. The low beam pattern is generally divided into four areas: the front area (area one), the core lighting area (area four), the far lighting area (area two) and the sign area (area three).
[0003] There are minimum illumination requirements for low beam three zones, the purpose of which is to illuminate the road signs above the road, and maximum illumination limits, the purpose of which is to prevent glare, causing the eyes of drivers or pedestrians in the opposite lane to receive too much light, posing a safety hazard. All three low beam zones are a very important part of the low beam light pattern setting.
[0004] The general setting method is to add a three-zone structure on the front surface or bottom of the lens, or a separate area on the reflector, or an additional optical surface on the primary lens. No matter which method is used, an additional area or structure is required to achieve the three-zone regulatory requirements. For adding a three-zone structure, the additional structure requires an additional mold insert or a special mold, which will affect the product molding. For adding an additional reflective surface, it is essentially two reflective surfaces. The reflector of the utility model is a reflective surface with a three-zone reflective surface. The curvature of the reflective surface is continuous, and no additional reflective surface and additional structure are required. Utility Model Content

[0040] The utility model is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the utility model, but do not limit the utility model in any form. It should be pointed out that for those of ordinary skill in the art, several changes and improvements can be made without departing from the concept of the utility model. These all belong to the protection scope of the utility model.
[0041] Embodiment 1:
[0042] like Figures 1 to 8 As shown, this embodiment provides a low beam three-zone vehicle light module system, including: a lens 1, a reflector assembly 2, a heat sink 4 and a light source 5; the reflector assembly 2 includes a reflector 21 and a reflector frame 22, and the reflector 21 is connected to the lens 1 through the reflector frame 22; a three-zone reflecting surface 211 is provided on the reflector 21; a light blocking strip 41 is provided on the heat sink 4, and a three-zone structure 411 is provided on the light blocking strip 41; light emitted by the light source 5: a part of the light is reflected by the three-zone reflecting surface 211 and then passes through the three-zone structure 411 to reach the lens 1; a part of the light is reflected by the reflector 21 and then directly reaches the lens 1. The three-zone reflection surface 211 is located at the root of the reflector and is continuous with the curvature of the entire reflector 21. The reflection angle of the light is controlled by controlling the change in the curvature of the reflector 21, thereby forming a three-zone light distribution range of the low beam. The three-zone structure 411 is located on the radiator light blocking strip 41 and is divided into three grooves. Since the three-zone regulations have S50RR, S50, S50LL, S100RR, S100, and S100LL test points, and there is a light intensity limit range, the three grooves correspond to the test points of the left, middle, and right areas of the above three-zone regulations. The light intensity of the test point is controlled by controlling the width of the groove, and the angle and uniformity of the light distribution in the three zones are controlled by controlling the position of the groove. The width and position of the three grooves can be arbitrarily combined and adjusted to meet regulatory requirements.
[0043] The heat sink 4 is provided with a light source heat dissipation boss 42, and the light source 5 is provided on the light source heat dissipation boss 42. There is an angle between the mounting surface of the light source heat dissipation boss 42 for setting the light source 5 and the reference platform of the heat sink 4. The size of the angle is 7° to 13°.
[0044] The low beam three-zone vehicle lamp module system also includes a light baffle 3, a light baffle 3; the light baffle 3 is arranged between the reflector 21 and the lens 1; the light emitted by the light source 5: a part of the light is reflected by the three-zone reflective surface 211 and then reaches the lens 1 through the three-zone structure 411; a part of the light is reflected by the reflector 21 and then reaches the lens 1 directly; a part of the light is reflected by the reflector 21 and then reaches the light baffle 3, and then reaches the lens 1 after being reflected by the light baffle 3. There is an angle θ between the reflective surface of the light baffle 3 and the horizontal axis.
[0045] The low beam three-zone vehicle lamp module system further includes a PCB board 6. In other embodiments, the light source 5 may also be disposed on the PCB board 6. There is an angle between the PCB board 6 and the horizontal axis.
[0046] In the existing three-zone low beam structure, the light passes through the top of the baffle 3, and the reflected light at the root of the reflector is blocked under the baffle 3. However, the utility model adjusts the setting method of the light source and the PCBA board, and sets a three-zone reflective surface 211 and a three-zone structure 411, so that the light that was originally blocked under the baffle can pass through under the baffle 3, and three-zone light distribution is realized.
[0047] In the existing low beam three-zone structure, due to the existence of the baffle 3 and the PCBA board, or other reasons, the light at the root of the reflector 21 will be blocked. The light source and the PCBA board of the utility model are different from the traditional settings. At the same time, the baffle 3 is rotated at an angle, and the light can be collected by the lens below to form a three-zone light distribution path.
[0048] The three-zone reflection surface 211 of the reflector 21 of the present invention is used to control the angle range, and the three-zone structure 411 on the heat sink is used to control the light intensity.
[0049] This embodiment also provides a vehicle lamp, comprising the above-mentioned low beam three-zone vehicle lamp module system.
[0050] Embodiment 2:
[0051] Those skilled in the art may understand this embodiment as a more specific description of Embodiment 1.
[0052] like Figure 1 As shown, this embodiment provides a low beam three-zone automobile lamp module optical system, including a lens 1, a reflector assembly 2, a light baffle 3, a heat sink 4, a light source 5 and a PCB board 6.
[0053] The lens 1 is made of polycarbonate (PC) or polymethyl methacrylate (PMMA) or glass.
[0054] The reflector assembly 2 includes a reflector 21 and a reflector frame 22. The reflector near the light source side is generally plated with aluminum to improve reflectivity. The reflector assembly material is BMC or high-temperature PC.
[0055] The light blocking plate 3 is formed by integral stamping, and the upper surface of the light blocking plate is a mirror surface that can reflect light. The material is aluminum.
[0056] The heat sink 4 includes a light shielding strip 41 for shielding the direct light emitted from the light source 5, thereby reducing the stray light of the vehicle lamp module system, and a three-zone structure 411 for controlling the light type and light intensity distribution of the three zones. The light source heat dissipation boss 42 is used for the patch and welding of the light source 5. The light source heat dissipation boss 42 is a high-precision positioning structure and needs to be processed twice during the production process to ensure its precision position deviation. Figure 4 As shown, there is an angle between the light source heat dissipation boss and the heat sink reference platform, which is used to improve the coupling utilization rate of the LED light source 5 and the reflector 21, and can greatly improve the optical efficiency. The angle is generally 7° to 13°, and the specific angle should be analyzed in combination with actual conditions.
[0057] Light source 5, such as Figure 1 and Figure 6 As shown, the light source 5 is mounted and positioned on the light source heat dissipation boss 42 or the PCB board 6, and the light source may have an angle relative to the horizontal axis or may not have an angle. Figure 1 As shown, the PCB board 6 is fixed on the heat sink 4.
[0058] The reflector assembly 2, the light baffle 3, the light source 5 and the PCB board 6 are all installed and fixed on the radiator 4, and the lens 1 is fixed on the reflector frame 22, and then fixed in a relative position with the radiator 4. Therefore, the light source 5, the reflector 21, the light baffle 3 and the lens 1 are on the basic fixed platform of the radiator 4, forming a relatively stable car light module optical system.
[0059] like Figure 1 As shown, the light diverging from the light source 5 is reflected by the reflective surface in the root area of the reflector 21. The reflective surface at the root cannot be used in the low beam main design light pattern. By setting and controlling the curvature of the root of the reflector 21, the light is allowed to pass from under the light baffle 3. The light baffle 3 has a rotation angle θ relative to the horizontal axis.
[0060] like Figure 2 As shown, the light blocking plate 3 adopts a rotation angle to improve the utilization rate of light, and is also beneficial for the light of the three zones to pass through from under the light blocking plate 3. There is a light blocking strip 41 on the light path, which is used to block the stray light directly emitted by the light source. There is a three-zone structure 411 on the light blocking strip 41, which is used to control the amount of light passing through to meet the requirements of the three-zone low beam. Finally, through the refraction of the lens 1, a low beam three-zone light pattern distribution is formed.
[0061] In summary, the three-zone light distribution of the low beam is achieved by controlling the root curvature of the reflector 21 and the three-zone structure 411 on the radiator. Since the reflector 21 and the three-zone structure 411 on the radiator are structures that cannot be directly viewed, subsequent adjustments and mold modifications will not affect the design, and the surface shape of the reflector 21 is a complete surface shape, which is more conducive to processing.
[0062] In other embodiments, Figure 6 As shown, the light diverged from the light source 5 is reflected by the reflective surface 211 on the reflector 21, the surface curvature of the reflective surface 211 needs to meet the requirements of the three-zone low beam, passes under the light baffle 3, and finally refracts through the lens 1 to form the light distribution required by the three-zone low beam. Alternatively, the light diverged from the light source 5 is reflected by the reflector 21 or directly controlled by other structures, passes under the light baffle 3, and finally refracts through the lens 1 to form the light distribution of the three-zone low beam. Alternatively, the light diverged from the light source 5 is reflected or directly controlled by any optical structure, passes under the light baffle 3, and finally refracts through the lens 1 to form the light distribution of the three-zone low beam.
[0063] The utility model utilizes the three-zone reflective surface at the root of the reflector, cooperates with a light baffle and a radiator, changes the light originally passing through the light baffle to passing through the bottom of the light baffle, realizes the light distribution requirement of the three zones, greatly improves the optical efficiency, reduces the control of components, and realizes a more stable optical effect.
