Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments of the present disclosure. Based on the embodiments of the present disclosure, all other embodiments obtained by those skilled in the art without creative work belong to the protection scope of the present disclosure.
[24] The purpose of the present disclosure 1s to provide a signal lamp for simulated traffic, which is used to simulate the process of a vehicle approaching the traffic signal lamp from far to near in vehicle testing.
[25] In order to make the above purposes, features and advantages of the present disclosure more obvious and easy to understand, the present disclosure is described in further detail below in combination with the accompanying drawings and specific embodiments.
[26] Fig. 11s a structural diagram of a signal lamp for simulated traffic provided by an embodiment of the present disclosure, as shown in Fig. 1, the signal lamp for simulated traffic, includes a distance acquisition simulation input unit 1, a control unit 2 and asignal lamp 3; wherein the distance acquisition simulation input unit 1 is connected to the control unit 2, and the distance acquisition simulation input unit 1 is configured to send distance information between the signal lamp 3 and a vehicle to the control unit 2; the control unit 2 is also connected to the signal lamp 3, and the control unit 2 is configured to control brightness and luminous area of the signal lamp 3 according to the distance information. Wherein, the distance acquisition simulation input unit 1 is a computer; and the control unit 2 is a single-chip microcomputer.
[27] Inthe embodiment, the distance acquisition simulation input unit 1 can also send information of the change law of the signal lamp 3 (except for distance information between the signal lamp 3 and the vehicle) to the control unit 2. The control unit 2 controls the brightness and luminous area of the signal lamp 3 according to the information of the change law.
[28] Inthe embodiment, the simulated traffic light also includes a power supply 4 for supplying power to the distance acquisition simulation input unit 1, the control unit 2 and the signal lamp 3.
[29] Fig. 2 is a structural diagram of the signal lamp provided by an embodiment of the present disclosure. As shown in Fig. 2, the signal lamp 3 includes a light source 9, a shell 7, a mask 11 and a light shield 8. The light source 9 is arranged on the shell 7, the mask 11 is covered on the light source 9 for protection, and the light shield 8 is arranged 5 onan outer edge of the light source 9 to reduce interference of external light to the signal lamp 3. The light source 9 is an LED light source, an incandescent lamp light source, a tungsten halogen lamp light source or a high-pressure gas discharge lamp light source.
[30] In the embodiment, the light source 9 is a centralized light source. The signal lamp 3 also includes a light blocking component 10, which is arranged in front of the mask, and the light blocking component 10 is used to adjust the luminous area of the centralized light source. Wherein, the light blocking component 10 is a light blocking part with a rotary opening and closing structure, and its driving mechanism can adopt a step motor. The step motor is connected to the light blocking component 10 through a gear transmission mechanism. As the distance between the signal lamp 3 and the test vehicle decreases, the step motor drives the gear transmission mechanism to drive the light blocking component to move, so as to gradually reduce a shielding area to the light source 9. By controlling the working voltage at both ends of the signal lamp 3, the control unit 2 continuously adjusts the brightness of the light source 9 on a premise of keeping a circular contour shape of the light emitting part of the light source 9 similar. [BI] Fig 3 is a structural diagram of a distributed light source provided by the embodiment of the present disclosure, as shown in Fig. 3. In the embodiment, the light source 9 can also be a distributed light source, and the distributed light source includes an inner light source 5, an intermediate light source and an outer light source 6. When only the inner light source 5 is on, the luminous area is the smallest, and when the inner light source 5, the middle light source and the outer light source 6 are on, the luminous area is the largest. As the distance between the signal lamp 3 and the test vehicle decreases, the distributed light source starts to emit light from the inner light source 5, gradually emits light from the inner layer to the outer layer, and the brightness increases accordingly. When the distance is the shortest, the outermost light source 6 also emits light and the brightness is the strongest.
[32] The present disclosure can simulate the process of a vehicle approaching the signal lamp from far to near by adjusting the brightness and luminous area of the signal lamp at a limited distance, and provide conditions for testing the response of the vehicle to the signal lamp at different distances. Compared with the actual road test, the present disclosure has high efficiency, low cost and high safety.
[33] Each embodiment in the specification is described in a progressive manner. Each embodiment focuses on the differences from other embodiments. The same and similar parts between each embodiment can be referred to each other.
[34] Specific examples are used in this article to illustrate the principles and implementation of the present disclosure. The description of the above examples is only used to help understand the core idea of the present disclosure; at the same time, for those of ordinary skill in the art, according to the idea of the present disclosure, there will be changes in the specific implementation and the scope of application. In summary, the content of this specification should not be construed as a limitation to the present disclosure.
