Description

Technical Field

[0001] The utility model relates to lighting equipment, and specifically, to a condenser, a high beam lighting unit and a vehicle lamp. Background Art

[0002] Currently, the low beam and high beam in vehicle headlamps are both mandatory functions. As mandatory functions, there are two design forms for the low beam and high beam lighting units: 1. The designs of the low beam and high beam are integrated in one lighting unit. 2. The low beam and high beam are separately designed.

[0003] However, whether the low beam and high beam are integrated in one lighting unit or separated into two lighting units, when the low beam is lit, the high beam cannot be lit. Therefore, at night, the low beam is a constant-on function, while the high beam is not constantly lit. When the low beam lighting unit is lit, the appearance of the high beam lighting unit is dark. The high beam lighting unit being in the off state will cause a sense of visual emptiness, greatly reducing the aesthetics of the entire vehicle lamp and also decreasing the competitiveness of the product.

Detailed implementation manners

[0028] The following will describe in detail the specific implementation manners of the present invention with reference to the accompanying drawings. It should be understood that the specific implementation manners described herein are only used to illustrate and explain the present invention, and the protection scope of the present invention is not limited to the following specific implementation manners.

[0029] In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, terms such as "formed", "provided with", "set", "connected", etc. should be understood in a broad sense. For example, the connection can be a direct connection, or an indirect connection through an intermediate medium. It can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate connecting member. It can be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0030] In the present utility model, without corresponding explanation, the orientation terms such as "upper", "lower", "left", "right", "counterclockwise", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. What is involved is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model; for the orientation terms of the present utility model, they should be understood in combination with the actual installation state.

[0031] The first aspect of the present utility model provides a high-beam lighting unit. As a specific embodiment of the high-beam lighting unit, refer to Figure 1-7 , which includes a high-beam light source 1, a condenser 2, a lens 3, and an accompanying light source 4. The condenser 2 includes a high-beam condenser 201 and an accompanying condenser 202. The light rays emitted by the high-beam light source 1 are adapted to be converged by the high-beam condenser 201 and then projected through the lens 3 to form a high-beam light pattern. The accompanying light source 4 is arranged corresponding to the accompanying condenser 202, so that the light rays emitted by the accompanying light source 4 are adapted to be converged by the accompanying condenser 202 and then projected through the lens 3 to form an accompanying lighting light pattern.

[0032] Based on the above basic implementation manner, in the low-beam working condition, the present utility model enables the accompanying light source 4 to be lit synchronously with the low-beam light source. The light rays emitted by the accompanying light source 4 can be converged by the accompanying condenser 202 and then projected through the lens 3 to form an accompanying lighting light pattern, so that the appearance of the high-beam lighting unit is in a lit state, avoiding a visual sense of emptiness and effectively improving the aesthetics of the vehicle's headlights.

[0033] It should be noted that there is no limitation on the arrangement form between the accompanying light source 4 and the high-beam light source 1. For example, refer to Figure 2 , the two can be arranged vertically. The high-beam light source 1 is the light source in the upper row, and the accompanying light source 4 is the light source in the lower row. Correspondingly, the high-beam condenser 201 is arranged above corresponding to the high-beam light source 1, and the accompanying condenser 202 is arranged below corresponding to the accompanying light source 4; or, the positions between the high-beam light source 1 and the accompanying light source 4 can also be exchanged with each other. Correspondingly, the positions between the high-beam condenser 201 and the accompanying condenser 202 are also exchanged with each other. In order to reduce the overall occupied volume of the condenser 2 and the number of components of the high-beam lighting unit, preferably, refer to Figures 3-5 , the high-beam condenser 201 and the accompanying condenser 202 are integrally formed parts, which greatly improves the integration degree and is convenient for installation and arrangement.

[0034] Refer to Figure 2, the high beam light source 1 includes a plurality of high beam photon emitting units arranged in parallel. Correspondingly, the high beam condenser 201 includes a plurality of high beam photon condensers, and the high beam photon condensers are arranged in one-to-one correspondence with the high beam photon emitting units, so that the light emitted by each high beam photon emitting unit can be collimated and converged through its corresponding high beam photon condenser, thereby improving the effect of light collimation and convergence and the light pattern quality of the high beam light pattern. Similarly, in order to improve the quality of the accompanying lighting light pattern and make the appearance of the high beam lighting unit look more beautiful when observed from the outside, the accompanying light source 4 also includes a plurality of accompanying sub-light emitting units 401, and the accompanying condenser 202 includes a plurality of accompanying sub-condensers 202-1. However, since the accompanying light source 4 is used to make the appearance of the high beam lighting unit in a lit state, the number of the accompanying sub-condensers 202-1 does not need to be exactly the same as the number of the accompanying sub-light emitting units 401, and it is only necessary that at least one of the plurality of accompanying sub-light emitting units 401 is provided with an accompanying sub-condenser 202-1, that is, at least one accompanying sub-light emitting unit 401 has an accompanying sub-condenser 202-1 corresponding to it.

[0035] As a specific implementation manner, the light incident surface of the lens 3 includes a plurality of sub-light incident surfaces 301, and the sub-light incident surfaces 301 are arranged in one-to-one correspondence with the accompanying sub-condensers 202-1, so that the light emitted by each accompanying sub-condenser 202-1 can be collimated and converged separately, thereby further ensuring the quality of the accompanying lighting light pattern.

[0036] It should be noted that since there is no specific brightness requirement for the accompanying lighting light pattern under the low beam working condition, the accompanying light source 4 only needs to be lit. However, in order to avoid its influence on the low beam light pattern and make the low beam light pattern not meet the relevant low beam regulations, the luminous intensity of the accompanying light source 4 should not be too strong and should be controlled within a reasonable design range, and this design range can be obtained through actual experiments; in addition, as a specific implementation manner, the accompanying light source 4 and / or the accompanying condenser 202 are not arranged at the position where the focus of the lens 3 is located, so as to avoid the light emitted by the accompanying light source 4 and / or the accompanying condenser 202 from forming light with strong brightness after being refracted by the lens 3.

[0037] Furthermore, in order to prevent the light emitted by the accompanying light source 4 from being too concentrated after being converged by the accompanying condenser 202 and avoid the excessive brightness value from affecting the low beam light pattern, in some specific embodiments, patterns can be provided on the light emitting surface of the accompanying condenser 202 to scatter the light, so that the light is more uniform after being projected by the lens 3 and the accompanying lighting effect is better. Specifically, see Figure 5, the high-beam condenser 201 and the accompanying condenser 202 are integrally formed. The light-emitting surfaces of the two together form a complete and continuously curved surface as the light-emitting surface of the condenser 2. Correspondingly, a complete and continuous first pattern 5 can be provided on the light-emitting surface of the condenser 2 corresponding to the light-emitting surface of the accompanying condenser 202; alternatively, when the accompanying condenser 202 consists of a plurality of accompanying sub-condensers 202-1, see Figure 4 , the light-emitting surfaces of the plurality of accompanying sub-condensers 202-1 are respectively provided with the first pattern 5, that is, the light-emitting surfaces of the plurality of accompanying sub-condensers 202-1 are provided with the first pattern 5 in one-to-one correspondence.

[0038] In some specific embodiments, at least one of the upper side surface and the lower side surface of the lens 3 is provided with a second pattern 6 to be able to eliminate or weaken the stray light emitted from the upper and lower side surfaces; and / or, the light-emitting surface of the lens 3 is provided with a third pattern 7. Specifically, the third pattern 7 is provided on the entire light-emitting surface of the lens 3, so as to be able to play a role in uniforming the light.

[0039] It should be noted that the pattern forms of the above-mentioned first pattern 5, second pattern 6 and third pattern 7 are not specifically limited. For example Figures 4-7 as shown, it can be a fisheye pattern arranged in a matrix, or it can be stripes, spherical patterns, etc.

[0040] In some specific embodiments, the incident surface of the lens 3 is a convex surface formed by the contour line of a convex curve sweeping along a first sweeping line. The first sweeping line is a straight line or a curve, and the extending direction of the first sweeping line is vertical, so as to be able to collimate and converge the light in the left-right direction; the light-emitting surface of the lens 3 is a convex surface formed by the contour line of a convex curve sweeping along a second sweeping line. The second sweeping line is a straight line or a curve, and the extending direction of the first sweeping line has a horizontal component, that is, the extending direction of the first sweeping line is horizontal, or has a certain angle with the horizontal, so that the light-emitting surface of the lens 3 can at least collimate and converge the light in the up-down direction.

[0041] In some specific embodiments, see Figure 1 and Figure 2 , the high-beam lighting unit of the present invention further includes a circuit board 8. The high-beam light source 1 and the accompanying light source 4 are both arranged on the circuit board 8, which improves the integration degree of the high-beam lighting unit of the present invention, reduces the space occupation, and is beneficial to realizing the miniaturization of the high-beam lighting unit. In addition, the high-beam lighting unit of the present invention further includes a heat sink 9. The condenser 2 and the lens 3 are both installed on the heat sink 9. When the condenser 2 is fixed on the heat sink 9, the condenser 2 presses and fixes the circuit board 8 on the heat sink 9 through the formed extending protrusion, realizing the heat dissipation of the light source.

[0042] In order to better understand the technical solution of the high-beam lighting unit of the present invention, the following description is made in combination with relatively preferred technical features.

[0043] The high-beam lighting unit of the present utility model includes a high-beam light source 1, a condenser 2, a lens 3, an accompanying light source 4, and a circuit board 8. The condenser 2 includes a high-beam condenser 201 and an accompanying condenser 202 arranged vertically. Both the high-beam light source 1 and the accompanying light source 4 are integrally arranged on the circuit board 8. The light emitted by the high-beam light source 1 is adapted to be converged by the high-beam condenser 201 and then projected through the lens 3 to form a high-beam light pattern. The accompanying light source 4 is arranged corresponding to the accompanying condenser 202, so that the light emitted by the accompanying light source 4 is adapted to be converged by the accompanying condenser 202 and then projected through the lens 3 to form an accompanying lighting light pattern. Among them, the accompanying light source 4 includes a plurality of accompanying sub-light-emitting units 401, the accompanying condenser 202 includes a plurality of accompanying sub-condensers 202-1, and the light-incident surface of the lens 3 includes a plurality of sub-light-incident surfaces 301. The accompanying sub-light-emitting units 401, the accompanying sub-condensers 202-1, and the sub-light-incident surfaces 301 are arranged in one-to-one correspondence, so as to be able to collimate and converge the light emitted by each accompanying sub-light-emitting unit 401 and ensure the quality of the accompanying lighting light pattern. In addition, neither the accompanying light source 4 nor the accompanying condenser 202 is arranged at the position where the focus of the lens 3 is located, so as to avoid the light emitted by the two being refracted by the lens 3 to form light with a stronger brightness. Moreover, a first pattern 5 for dispersing light is provided on the light-emitting surface of the accompanying condenser 202, so that the light emitted by the accompanying condenser 202 is more uniform after being projected through the lens 3, and the accompanying lighting effect is better. Second patterns 6 are provided on both the upper side and the lower side of the lens 3 to be able to eliminate or weaken the stray light emitted from the upper and lower sides. The third pattern 7 is provided on the entire light-emitting surface of the lens 3, so as to be able to play a role in uniforming the light.

[0044] Through the above technical solutions, the high-beam lighting unit of the present utility model can, under the low-beam working condition, enable the accompanying light source 4 to be lit synchronously with the low-beam light source, thereby forming an accompanying lighting light pattern, making the appearance of the high-beam lighting unit in a lit state, avoiding a visual sense of emptiness, effectively improving the aesthetic degree of the vehicle's entire headlight, and being able to effectively avoid the light intensity of the accompanying light source 4 being too high and prevent the generated accompanying lighting light pattern from affecting the low-beam regulations.

[0045] The second aspect of the present utility model provides a condenser, which is the condenser 2 in the high-beam lighting unit provided in the first aspect of the present utility model. The condenser 2 integrates a high-beam condenser 201 and an accompanying condenser 202, and can cooperate with the accompanying light source 4 to generate an accompanying lighting light pattern, making the appearance of the high-beam lighting unit in a lit state, avoiding a visual sense of emptiness, and effectively improving the aesthetic degree of the vehicle's entire headlight.
