Description

Technical Field

[0001] The utility model relates to the technical field of automobile high and low beam lamps, in particular to a composite double-cup high and low beam lamp. Background Art

[0002] Conventional high and low beam lamps use a separate high beam lamp and a separate low beam lamp. The disadvantage of this structure is that the high and low beams are emitted respectively by two independent lamps, which greatly increases the size of the lamp.

[0003] The second method is to cut off the upper part of the low beam lens to make a high beam lens, and then the high beam emits light in a straight light manner. The disadvantage of this structure is that both the low beam and the high beam can only use half of the lens, and the light efficiency is low. Utility Model Content

[0004] In view of the above-mentioned shortcomings, the purpose of the utility model is to provide a composite double-cup high and low beam lamp, in which the low beam light source and the high beam light source share the same lens, thereby effectively improving the light efficiency without increasing the volume of the entire lamp.

[0008] A low beam lamp assembly, comprising a low beam light source and a low beam reflector bowl disposed below the low beam light source;

[0009] A lens is located just in front of the low-beam light source and the high-beam light source.

[0010] As a further improvement of the present invention, the lens is a structure close to half a sphere.

[0011] As a further improvement of the present invention, the high beam reflective bowl is a flat quarter ellipsoid structure, and a fan-shaped light-transmitting surface is formed near one end of the lens, with the middle extending toward one end of the low beam light source.

[0012] As a further improvement of the present invention, the high-beam light source is arranged below the end of the high-beam reflective bowl away from the fan-shaped light-transmitting surface.

[0013] As a further improvement of the present invention, the high beam reflective bowl is tilted downward toward one end of the lens.

[0014] As a further improvement of the present utility model, the low beam reflective bowl is a quarter ellipsoid structure.

[0015] As a further improvement of the present invention, the overall volume of the low beam reflector bowl is smaller than the overall volume of the high beam reflector bowl.

[0016] As a further improvement of the utility model, the low beam reflective bowl is arranged to be inclined downward toward the end away from the lens.

[0017] As a further improvement of the present invention, the low beam light source is arranged above the end of the low beam reflective bowl away from the lens.

[0018] As a further improvement of the present invention, the low beam light source and the high beam light source are both LED light sources.

[0019] The beneficial effects of the utility model are:

[0020] A high-beam reflector bowl is arranged on the high-beam light source, and a low-beam reflector bowl is arranged under the low-beam light source, so that the high-beam light source can be reflected onto the lens through the high-beam reflector bowl, and the low-beam light source can be reflected onto the lens through the low-beam reflector bowl.

[0032] Please refer to Figures 1 to 5 The utility model embodiment provides a composite double-cup high and low beam lamp, comprising:

[0033] A high beam lamp assembly 1, comprising a high beam light source 11, and a high beam reflector 12 disposed above the high beam light source 11;

[0034] A low beam lamp assembly 2, comprising a low beam light source 21, and a low beam reflector 22 disposed below the low beam light source 21;

[0035] A lens 3 , wherein the lens 3 is located in front of the low-beam light source 21 and the high-beam light source 11 .

[0036] By setting a high beam reflector 12 on the high beam light source 11 and a low beam reflector 22 under the low beam light source 21, the high beam light source 11 can be reflected onto the lens 3 through the high beam reflector 12, and the low beam light source 21 can be reflected onto the lens 3 through the low beam reflector 22. The low beam light source 21 and the high beam light source 11 share the same lens 3, thereby effectively improving the lighting efficiency without increasing the volume of the entire lamp, eliminating the trouble of preparing two lenses separately, and facilitating use.

[0037] Regarding the specific structural arrangement of the lens 3, as shown in FIG. Figures 1 to 3 As shown, the lens 3 is a structure close to half a sphere, so that the light emitted by the high-beam light source 11 and the low-beam light source 21 is refracted accordingly, making the light pattern clear and effectively improving the lighting effect. There is no need to cut the upper and lower parts into the high-beam lens 3 and the low-beam lens 3 respectively, which saves production steps, improves production efficiency, and ensures the volume of the entire lamp.

[0038] Regarding the specific structural arrangement of the high beam reflector bowl 12, as shown in FIG. Figures 1 to 3 As shown, the high beam reflector 12 is a flat quarter ellipsoid structure, and a fan-shaped light-transmitting surface 121 is formed near the end of the lens 3, and the middle part of the fan-shaped light-transmitting surface 121 extends toward the end of the high beam light source 11. The high beam light source 11 is arranged below the end of the high beam reflector 12 away from the fan-shaped light-transmitting surface 121, so that the high beam reflector 12 reflects the multi-angle light emitted by the high beam light source 11 to the lens 3 respectively, and refracts outward through the lens 3, thereby forming a clear light pattern and improving the light effect. The structure in which the middle part of the fan-shaped light-transmitting surface 121 extends toward the high beam light source 11 makes the high beam light source 11 near the lens 3 direct light, and the direct light is directly emitted outward through the refraction of the lens 3, effectively preventing the light from the high beam light source 11 near the lens 3 from being reflected by the high beam reflector 12, resulting in the situation that the angle is too low and cannot be refracted by the lens 3, thereby improving the light utilization rate of the composite double-cup high and low beam lamp.

[0039] In order to further improve the utilization rate of the light emitted by the high beam light source 11, Figures 1 to 3 As shown, the high beam reflective bowl 12 is tilted downward toward one end of the lens 3, that is, the end of the high beam light source 11 close to the lens 3 is pressed downward, and the end away from the lens 3 is rotated upward, so that the light from the middle part of the high beam light source 11 slightly toward the transparent end can also be reflected onto the lens 3 through the high beam reflective bowl 12, and refracted outward through the lens 3, thereby forming a clear light pattern and improving the light effect. The light emitted from the end of the high beam light source 11 closer to the lens 3 is directly projected onto the lens 3 through the fan-shaped light-transmitting surface 121, and refracted through the lens 3, thereby effectively improving the light utilization rate of the composite double-cup high and low beam lamp.

[0040] The tilt angle of the high-beam reflector 12 can be set according to the distance between the high-beam light source 11 and the high-beam reflector 12 and the distance between the high-beam light source 11 and the lens 3 , so no specific limitation is made in this embodiment.

[0041] The curvature of the sector-shaped light-transmitting surface 121 can be adjusted according to the distance between the high-beam light source 11 and the high-beam reflective bowl 12 and the distance between the high-beam light source 11 and the lens 3 , so no specific limitation is made in this embodiment.

[0042] Regarding the specific structural arrangement of the low beam reflector bowl 22, as shown in FIG. Figures 1 to 3 As shown, the low beam reflective bowl 22 is a quarter ellipsoid structure, and the low beam light source 21 is arranged above the end of the low beam reflective bowl 22 away from the lens 3, so that the low beam reflective bowl 22 reflects the multi-angle light emitted by the low beam light source 21 onto the lens 3 accordingly, and refracts outward through the lens 3, thereby forming a clear light pattern and improving the lighting effect.

[0043] In order to further improve the utilization rate of the light emitted by the low beam light source 21, Figures 1 to 3 As shown, the low beam reflector 22 is tilted downward toward the end away from the lens 3, that is, the end of the low beam reflector 22 away from the lens 3 is pressed downward, and the end close to the lens 3 is rotated and moved upward toward the lens 3, so that the light emitted from the middle of the low beam light source 21 slightly downward and close to the lens 3 can also be reflected to the lens 3 through the low beam reflector 22, and refracted outward through the lens 3, so as to form a clear light pattern and improve the light effect. The light emitted from the end of the low beam light source 21 close to the lens 3 that is not reflected by the low beam reflector 22 can also be directly projected onto the lens 3, thereby effectively improving the light utilization rate of the composite double-cup high and low beam lamp.

[0044] The tilt angle of the low-beam reflector 22 can be set according to the distance between the low-beam light source 21 and the low-beam reflector 22 and the distance between the low-beam light source 21 and the lens 3 , so no specific limitation is made in this embodiment.

[0045] In order to further improve the light utilization rate of the low beam light source 21 and the high beam light source 11 and reduce the production cost, Figures 1 to 3 As shown, the overall volume of the low beam reflector 22 is smaller than the overall volume of the high beam reflector 12. The high beam light source 11 can better reflect the emitted light onto the lens 3 through the larger high beam reflector 12, and refract it to a farther place through the lens 3. The low beam light source 21 can reflect the light onto the lens 3 through the smaller low beam reflector, and refract it to a closer place through the lens 3, thereby forming a clear light pattern and improving the light effect. The corresponding volume size setting reduces the production cost and improves the production efficiency of the composite double cup high and low beam lamp on the basis of ensuring the light pattern and light effect.

[0046] Preferably, the low beam light source 21 and the high beam light source 11 are both LED light sources, which are inexpensive and highly durable, effectively reducing production costs and ensuring the service life of the composite double-cup high and low beam lamp.

[0047] As for the installation method of the high beam light source 11, the high beam reflector 12, the low beam light source 21, the low beam reflector 22 and the lens 3, the high beam light source 11, the high beam reflector 12, the low beam light source 21, the low beam reflector 22 and the lens 3 can be installed on a substrate or on a bracket accordingly, and the installation method can be set according to actual conditions, so no specific limitation is made in this embodiment.

[0048] It should be noted that the composite double-cup high and low beam lamp disclosed in the utility model is an improvement on the specific structure, and the specific control method is not the innovation point of the utility model. The LED lamp and other components involved in the utility model can be general standard parts or components known to those skilled in the art, and their structure, principle and control method are all known to those skilled in the art through technical manuals or conventional experimental methods.

[0049] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, other structures obtained by adopting the same or similar technical features as the above embodiments of the present invention are within the protection scope of the present invention.
