For example, when a right turn is desired, then the opposite instruction is issued. More specifically, the driving plate 180 of the present embodiment is disposed under the base plate 110. More specifically, the driving board 180 is mounted on the lower surface of the heat dissipation substrate 110. The drive plate 180 also provides current for the operation of the first light source 120, the second light source 130.

The left-right rotation is suitable for the follow-up adjustment of the turning running of the automobile, and the up-down rotation is suitable for the follow-up adjustment of the ascending and descending running of the automobile. In the present embodiment, the driving mechanism 300 is used to drive the lens lamp 100 to rotate left and right with respect to the mounting bracket 200, and in other embodiments, the driving mechanism may drive the lens lamp 100 to rotate up and down with respect to the mounting bracket 200.

Further, as shown in fig. 3 and 4, in this embodiment, the connection assembly includes a connection member and a mounting hole 420 matched with the connection member for accommodating the connection member, where the connection member is a connection screw and a connection rod.

The adapter rack 210 is designed to facilitate installation of the turbine 500 and avoid the problem of insufficient space for the main body frame of the mounting bracket 200. When the turbine 500 rotates, the mounting bracket 200 is theoretically driven to rotate, but since the mounting bracket 200 is fixedly mounted on the automobile, the mounting bracket 200 is fixed, and the lens lamp 100 is movably connected with the mounting bracket 200, under the condition that the mounting bracket 200 is fixed, the lens lamp 100 can be rotated, so that the following rotation of the lens lamp 100 is realized, and a state diagram of the following lamp in different steering states of the automobile is shown in fig. 8.

More specifically, in the present embodiment, the first lens portion 141 and the second lens portion 142 have the same size, the first lens portion 141 and the second lens portion 142 are located in the lower half area of the light-emitting lens 140, and the third lens portion 143 is located in the upper half area of the light-emitting lens 140. More specifically, the number of the third lens portions 143 in the present embodiment is 2, and the third lens portions are respectively located above the first lens portion 141 and the second lens portion 142.

Further, the first light source 120 comprises a first LED emitter 121 and a first reflecting cup 122 for receiving light from the first LED emitter 121, the light receiving rate of the first reflecting cup 122 is greater than 80%, the second light source 130 comprises a second LED emitter 131 and a second reflecting cup 132 for receiving light from the second LED emitter 131, and the collecting efficiency of the second reflecting cup 132 to the second LED emitter 131 is greater than 80%. The car lamps in the aftermarket are mainly composed of (1) a low beam light source and a high beam light source which are respectively arranged on the upper surface and the lower surface of a heat dissipation substrate, and (2) the luminous surfaces of the low beam light source and the high beam light source are upward, but the installation surface of the high beam light source is lower than that of the low beam light source. The problem that (1) kind car light exists is the heat dissipation problem and because the car light that heat dissipation base plate thickness leads to goes out the problem that light efficiency is not high enough, and (2) kind car light is because need satisfy the requirement that high beam reflector cup can not shelter from the light of low beam light source, and the light efficiency of high beam light source is not high enough. The design of front loading lamp has partial car light to have and installs a plurality of luminescent light sources as low beam light source at the upper surface of radiating substrate, but the luminescent plate of receipts light is the disjunctor formula structure more than 3 or 3, and is very low to luminescent light source's receipts light efficiency, usually is less than 70%, and light utilization ratio is low, and car light luminance is not enough. In this way, the front-mounted lamp is required to be additionally mounted with a high beam light source below the heat dissipation substrate.

Further, the light emitting surfaces of the first LED light emitter 121 and the second LED light emitter 131 are not higher than the vertices of the first light shielding sheet 1511 and the second light shielding sheet 1512 (the vertices of the first light shielding sheet 1511 and the second light shielding sheet 1512 refer to the highest point at the transition connection point of the light shielding sheets of different heights of the first light shielding sheet 1511 and the second light shielding sheet 1512), so that the light-cutting mechanism 150 can only shield a very small amount of light of the first light source 120 and the second light source 130, and the light of the first light source 120 and the second light source 130 can be emitted from the whole light emitting surfaces of the first lens portion 141 and the second lens portion 142, so that the light-emitting efficiency is very high. Further, the light shielding sheet 151 according to the present application has an asymmetric structure, and the length of the first light shielding sheet 1511 is greater than the length of the second light shielding sheet 1512 in the direction parallel to the width direction of the lens car light 100, and the weight difference between the two is less than 10%. As shown in fig. 9, the light shielding sheet 151 needs to be connected to the driving member 152, and the connection position is located substantially at the middle of the light shielding sheet 151, that is, the connection position of the driving member 152 for driving the light shielding sheet 151 and the light shielding sheet 151 is located substantially at the middle of the light shielding sheet 151. By adopting the asymmetric design, the whole of the shading sheet 151 can be kept balanced, enough space can be reserved for the connecting position, and the light efficiency and the cost can be well considered. If the problem of connection between the light shielding plate 151 and the driving member 152 and the problem of weight balance are omitted, the light emitted from the second light source 130 is concentrated due to higher brightness, and the light is narrower in width, so that the area to be shielded is smaller, and thus the length of the second light shielding plate 1512 can be reduced. However, if the difference in weight between the two ends of the light shielding sheet 151 is large, it is difficult to ensure the balance of the light shielding sheet 151 well. The technical scheme adopts an asymmetric structural design, and can simultaneously meet the requirements of assemblability, balance and high light efficiency.

More specifically, in the present embodiment, the first arc piece 1511a is disposed near the fourth arc piece 1512d, that is, the first arc piece 1511a and the fourth arc piece 1512d are located in the middle of the light-cutting piece 151, and the second arc piece 1511b and the third arc piece 1512c are located at both ends of the light-shielding piece 151, which is suitable for the driving mode in which the domestic driver sits in the left driving cab. In the case where the driver sits in the right driving cab, it is possible that the second and third arcuate pieces 1511b and 1512c are located in the middle of the cut piece 151, and the first and fourth arcuate pieces 1511a and 1512d are located at both ends of the cut piece 151. Further, in this embodiment, the first arc-shaped piece 1511a and the second arc-shaped piece 1511b are integrally formed, the third arc-shaped piece 1512c and the fourth arc-shaped piece 1512d are integrally formed, and the first light shielding piece 1511 and the second light shielding piece 1512 are integrally formed, that is, the light shielding piece 151 is integrally formed.
