It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally arranged component at the same time.

[0030] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0031] like Figures 1 to 5 As shown, the embodiment of the utility model provides a daytime running light for automobile with strong focusing, comprising a housing 1, a first reflector 21, a second reflector 22, a first LED lamp 31, a second LED lamp 32, a lamp board 4, a light-transmitting cover 5 and a connector 6;

[0032] The housing 1 is provided with a housing chamber, the first reflector 21 is provided in the housing chamber, a plurality of arc-shaped chambers 210 are provided at the bottom of the first reflector 21 along the length direction, a avoidance hole 211 is provided at the bottom of the arc-shaped chamber 210, the first LED lamp 31 is located in the avoidance hole 211, and a plurality of the first LED lamps 31 are electrically connected to the lamp board 4, a focusing concave portion 212 is provided on the back wall of the arc-shaped chamber 210, and the focusing concave portion 212 is used to gather and reflect the light emitted by the first LED lamp 31;

[0033] In this embodiment, the first LED lamp 31 is a daytime running light. The focusing concave portion 212 on the back of the arc-shaped chamber 210 can effectively converge and reflect the light emitted by the first LED lamp 31 to reduce astigmatism and concentrate on improving the light output brightness of the first LED lamp 31 so that it can be clearly seen by other drivers and pedestrians even under strong sunlight.

[0034] The first reflector 21 is provided with a light-transmitting groove 213, the light-transmitting groove 213 is a conical structure, and the cross-sectional area of ​​the light-transmitting groove 213 gradually increases along the light-emitting direction. The second reflector 22 is provided at the back of the light-transmitting groove 213, the second LED lamp 32 is provided in the second reflector 22, and the inner wall surface of the second reflector 22 is provided with a corrugated structure 221;

[0035] In this embodiment, the second LED lamp 32 is a high and low beam integrated lamp; the second reflector 22 can effectively gather and reflect the light emitted from the second LED lamp 32, thereby improving the focusing effect of the second LED lamp 32; the light-transmitting groove 213 is a conical structure, and its cross-sectional area gradually increases along the light-emitting direction. Such a configuration enables the light emitted by the second LED lamp 32 to be fully diffused, thereby covering a larger area and achieving a more uniform lighting effect; the configuration of the corrugated structure 221 can increase the surface area of ​​the second reflector 22, thereby improving the heat dissipation performance and avoiding local overheating that affects the service life of the second LED lamp 32. It should be noted that a through hole for the second LED lamp 32 to be installed through is provided on the back of the housing 1, so as to achieve the rapid replacement of the second LED lamp 32.

The connector 6 can transmit power from the vehicle's electrical system to the first LED lamp 31 and the second LED lamp 32. The light-transmitting cover 5 can scatter the light emitted by the first LED lamp 31 and the second LED lamp 32 to evenly distribute the light, reduce glare, and improve driving safety and comfort.

[0037] Furthermore, the first reflector 21 and the first reflector 22 are made of aluminum alloy. Aluminum alloy has a high reflectivity and can effectively gather and reflect the light emitted by the first LED lamp 31 and the second LED lamp 32 to improve the focusing effect.

[0038] like Figure 1 As shown, further, the concave light focusing portion 212 is an asymmetric structure, and a reflective plane portion 214 is provided at the side end of the concave light focusing portion 212. The asymmetric concave light focusing portion 212 can directionally focus and reflect light according to the position of the left or right running lights, so that the light is more accurately irradiated on the road ahead.

[0039] Furthermore, a silver coating is applied on the light-concentrating concave portion 212 and the reflective plane portion 214. The silver coating has a higher light reflectivity than aluminum alloy, which can effectively reduce the loss of light during the reflection process, so that more light can be reflected and utilized, thereby enhancing the light gathering effect.

[0040] Furthermore, an optical brightness enhancement film is provided on the inner surface of the light-transmitting cover 5. The optical brightness enhancement film has an optical structure of a micro-prism array inside, which can increase the intensity of light passing through the light-transmitting cover 5 and make the light brighter.

[0041] like Figure 4 As shown, further, the first reflector 21 is connected to the housing 1 by bolts, and the second reflector 22 is connected to the housing 1 by buckles. Connecting the first reflector 21 to the housing 1 by bolts can improve the installation stability of the first reflector 21 and prevent loosening; connecting the second reflector 22 to the housing 1 by buckles can achieve rapid assembly and improve production efficiency.

[0042] like Figures 2 to 4 As shown, further, a block 11 is provided on the side wall of the shell 1, and a bayonet 51 is provided on the side wall of the light-transmitting cover 5. The bayonet 51 is connected to the block 11 by snapping. Such a configuration can increase the overall assembly rate and improve production efficiency.

[0043] The first LED lamp 31 of the utility model is a daytime running light. A focusing concave portion 212 is provided on the back of the arc-shaped chamber 210, which can effectively converge and reflect the light emitted by the first LED lamp 31 to reduce the phenomenon of astigmatism and concentrate on improving the light output brightness of the first LED lamp 31, so that it can be clearly seen by other drivers and pedestrians even in strong sunlight; the second LED lamp 32 is an integrated high and low beam lamp; the second reflector 22 can effectively gather and reflect the light emitted from the second LED lamp 32, thereby improving the focusing effect of the second LED lamp 32; the light-transmitting groove 213 is a conical structure, and its cross-sectional area gradually increases along the light emitting direction. Such a setting allows the light emitted by the second LED lamp 32 to be fully diffused, thereby covering a larger area and achieving a more uniform lighting effect; the setting of the corrugated structure 221 can increase the surface area of ​​the second reflector 22, thereby improving the heat dissipation performance and avoiding local overheating that affects the service life of the second LED lamp 32.

[0044] As described above, the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features can be replaced by equivalents.
