[0007] Preferably, the lower side wall of the base is provided with symmetrical adhesive backing.

[0008] Preferably, the lower side wall of the base is provided with symmetrical air holes, and air-permeable membranes are provided inside the two air holes.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] (1) The lighting speed of this application is fast: when the door is opened, the pedal light will respond and light up in time, and there is no phenomenon of delayed lighting of the pedal light after opening the door;

[0011] (2) High recognition: This pedal light is illuminated by light sources of different colors at both ends of the light guide. The light rays converge in the light guide to achieve a contrasting color effect. At the same time, the color of the light source can be changed. The contrasting color effect is distinctive, the transition of the light contrasting color change is uniform, and the welcoming effect is highly recognizable.

[0012] (3) Vibration and impact resistance: Because LED high-mounted brake lights have no filaments, they convert electrical energy directly into heat energy, so they are resistant to vibration and impact;

[0013] (4) Save energy: LED lights consume much less energy than incandescent lights.

[0014] (5) LED + light guide: The light guide solution only requires the installation of light-emitting units at one or both ends of the light guide. Compared with lamps with large light-emitting surfaces, this solution reduces the use of LEDs and saves product costs. The back of the light guide is designed with reflective serrations, which destroys the complete reflection inside and allows light to flow out from the surface of the light guide. This solution greatly increases the efficiency of light use, saves energy, and also significantly improves the uniformity of light. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Example:

[0021] See also Figure 1-2, the utility model provides a technical solution:

[0022] A welcome pedal light in the form of a light-contrast color for an electric vehicle comprises a lamp housing 1 and a base 2. The base 2 is arranged at the lower end of the lamp housing 1. The lamp housing 1 and the base 2 are welded and fixed. A light guide 3 is arranged at the lower end of the lamp housing 1. The light guide 3 is fixedly connected to the upper side wall of the base 2 by self-tapping screws 8. A reflective film 4 is arranged at the lower end of the light guide 3. The reflective film 4 is adhered to the inside of the base 2. An electronic component assembly 5 is arranged at the lower end of the reflective film 4.

[0023] The lower side wall of the base 2 is provided with symmetrical adhesive 6 .

[0024] Symmetrical air holes are provided on the lower side wall of the base 2, and air permeable membranes 7 are provided inside the two air holes to facilitate heat dissipation of the lamp body and avoid damage due to high temperature generated inside the lamp after long-term use.

[0025] This lamp is installed at the door pedal and fixed by the base 2 buckle and the backing glue 6. The structural shape of the welcome pedal lamp assembly is designed according to the structural shape of the door pedal and the pedal light type.

[0026] The lamp is installed at the door pedal, so there are certain airtight requirements. If the airtightness is poor, rainwater will seep into the lamp when the door is opened on rainy days, causing the lamp to short-circuit and fail. The lamp housing 1 and the base 2 of the lamp are fixed by ultrasonic welding. There are 3 positioning columns, 10 single-sided buckles and two adhesives 6 on the back of the lamp base 2. The positioning is done by the positioning columns, the buckles are connected and the adhesive 6 is pasted and fixed. The middle positioning column is used for main positioning, and the positioning columns at both ends are used for auxiliary positioning. The lamp is guided by the positioning columns from top to bottom in the Z direction, and then the buckles are inserted into the door pedal contact point. At the same time, the adhesive 6 is pasted on the inner groove surface of the pedal to fix it. Because the lamp is small in size and light in weight, the buckle connection meets the installation requirements and does not require screw locking. The LED light source is located on both sides of the lamp, and is integrated with the light board and the wiring harness into the electronic component assembly 5. The light guide 3 is installed on the base by screw locking. The two ends of the light guide 3 serve as the light input ends of the LED light source. At the same time, a reflective film 4 with the same length as the light guide 3 is attached to the base 2 under the light guide 3 to improve the optical utilization rate. The lamp is installed on the door pedal at a low position, so passengers can see the ambient light effect of the welcome pedal lamp when they open the door.

[0027] The lamp adopts the LED plus light guide solution. The so-called light guide 3 is a long light-guiding plastic element in the shape of a conduit. Its shape can be designed according to actual modeling requirements. LED plus light guide means that the light emitted by the LED light source enters at one end or both ends of the light guide, and the light enters the light guide 3 from both sides. Because the back of the light guide 3 is designed with reflective sawtooth, the complete reflection inside it is destroyed, so that the light flows out from the surface of the light guide, realizing the light-emitting modeling of the lamp with the light guide modeling. In addition, the LED light sources at both ends of the light guide can be controlled to change different colors separately, realizing the welcome atmosphere light effect in the form of contrasting colors.

[0028] Working principle:

[0029] Pass the electronic component assembly 5 through the rubber plug hole through the base 2, clamp the rubber plug, clamp the PCB boards on both sides on the buckles of the base 2, stick the reflective film 4 to the inside of the base 2 cavity, lock the light guide 3 to the base 2 with self-tapping screws 8, fix the lamp housing 1 and the base 2 small assembly by ultrasonic welding, and stick the adhesive 6 and the breathable film 7 to the lower surface of the welded lamp body.
