Change, _ Wei second law, that the weight of the (four) weight 132 9 200940381 corresponds to different deceleration, so that the line sexy 13 corresponds to the output of different signals to the towel control unit 2G. In addition, when the defensive acceleration caused by the brake starts to slow down, the stress caused by the inertia of the weight 132 will also be slowed down synchronously, so that the weight 132 is relatively applied to the pressure sensing element. Stretching or pushing on 丨31 will also disappear relatively. 4. Inductive sensing 1114 (such as the fifth riding): The inductive sensor 14 is provided with a circuit composed of a fixed metal piece 141 and a movable metal piece 142.感应 The inductive sensor 14 uses the movable metal > 142 to swing left and right under the action of the vehicle brake deceleration inertial force, so that the capacitance value or the magnetic field value existing between the fixed metal piece 141 and the movable metal piece 142 The change is designed to correspond to different decelerations according to the capacitance value or the magnetic field value, so that the inductive sensor 14 outputs different signals to the central control unit 2〇. However, the above four types of sensors only need to be set to a single group to play and achieve the effect and purpose of sensing the deceleration of the brakes, and the following sensor type can only be used in each group. Sensing a single deceleration, so two sets of sensors must be set at the same time to sense different magnitudes of deceleration when braking. The horizontal sensor 15 (as shown in the sixth and seventh figures): the horizontal senser π can be in the form as shown in the sixth figure, and is provided with a slider 151 and a spring 152 sensing element 153, the spring 152 It is connected between the slider 丨51 and the 誃 sensing element 153. Furthermore, the horizontal sensor 15 can also be in the form of the first and the bottom of the magazine 152', and the end of the magazine 152' is connected to the slider 151, and the 200940381 = one end is set at the fixed position. The sensing element 153' is destroyed by the path of the sliding movement. When the car body is in a horizontal state, the 151, 151 turns to the position of the towel at the horizontal level. When the vehicle is in the W-car, the vehicle body is tilted toward the front of the vehicle, and the slider (5) is adapted to overcome the spring force of the spring 152 and the spring force, and the spring force is directed to the sensing element 153, so that the horizontal sensor 15 corresponds to the horizontal sensor 15 Outputting signals, and; the springs 152, 152 can be set by the Newton's second law of motion, which is greater than that in the preferred embodiment. When the deceleration two-level sensor 15 is used, both sets must be set simultaneously. The horizontal sensor 15 (i.e., 'whether or not the form as shown in the sixth figure is used, or the form as shown in the seventh figure is used, the two sets of horizontal senses are set. The H 15 may be a _ form, or an unclear type, and the _ type is only shown in a single group, and the springs 152 and 1 provided in the two sets of horizontal sensors 15 are springs with different elastic coefficients. 152, 152, and the slider 15 151 of the level sensor 15 is different at the time of touching the sensing elements 153, 153, and the lying design field should have different deceleration values, so that the level The sensors 15 respectively correspond to the output signals to the central control unit 20. For example, the two sets of the horizontal sensors 15 are respectively set to one of the horizontal sensors 15 to detect a higher deceleration value (for example, 4 '〆), and the other horizontal sensor 15 side is a lower deceleration value (for example, For the application of 2 5m/s2), the level sensors 15 respectively output the 200940381 output signal to the central control unit 2 according to the set detection value. The central control unit 20 is a processing reference circuit, and is connected to the deceleration sensing unit 10 and the illumination unit 3, and simultaneously receives the vehicle speed signal obtained by detecting the handle, and Acceleration_Unit 10 • Deceleration signal corresponding to the output drive signal. The acquisition of the speed signal is achieved by the special-responsible _ the sense of speed, the rib_vehicle body, the output speed of the output shaft or the wheel speed, and the corresponding output 峨, or directly capture the speed of the vehicle body. The signal is used as a speed signal. When the brake signal is obtained by the brake pedal, the component of the brake pedal is connected, and the corresponding output of the brake pedal is activated when the brake pedal is actuated. In the preferred embodiment, the central control unit 20 processes the vehicle speed signal, the brake signal, and the deceleration signal by a program operation or a hardware circuit, so that the central (four) unit 2G is illuminating the lining drive signal. Unit 3G. The towel central control unit 2G screams that the vehicle mode and the general killing mode are used to make the central control unit 2 according to the speed signal, the brake signal and the acceleration signal, and (4) should be an emergency brake. Mode or general brake* mode. In the emergency braking mode, the central control unit 2 () drives the lighting unit Q to ride in the general mode, and the central (four) unit 2 〇 drives the lighting unit (10) to display a strange flash. The road and the light-emitting unit 3 receive the driving signal of the central control unit 20, so that the light unit 30 is activated to emit light. Continued π refers to the eighth _, which is the schematic diagram of the architecture of the second embodiment of the emergency brake warning luminaire. In the preferred embodiment, the lamp is installed at the rear of the vehicle body, and can be regarded as a third fresh lamp or a left and right hybrid lamp. The lamp 2 is provided with a central control unit 2〇 and a light-emitting unit 30'. In addition, the lamp is externally connected with a set of minus acceleration sensing unit 10' disposed on the vehicle body, wherein: • the sense of deceleration The measuring unit 10 is a circuit composed of a sensor and is electrically connected with the central control unit 20' to reduce the acceleration of the vehicle when the vehicle is braked.
