Light guide type vehicle standard level LOGO lamp and light guide method thereof

Abstract

The invention discloses a light guide type vehicle standard grade LOGO lamp and a light guide method thereof, comprising a bottom shell, wherein a mounting slot is formed in the middle in the bottom shell, a circuit board is arranged on the bottom shell, an LED illuminating source and a control unit are integrated on the circuit board, the back of the circuit board is clamped on the mounting slot,the LED illuminating source and the control unit are connected with an external power source and a controller by a wiring harness, while a light guide panel, a mask, a decorative frame and an LOGO lampshade mounted on the bottom shell are sequentially arranged on the front positions of the circuit board; the circuit board, the light guide panel and the mask all adopts optical design, so that light of the LED lamp are better in uniformity after passing a path of collineation, total reflection, refraction, reflection and re-refraction, and is not affected by the shape of the LOGO lamp, and thusbeing especially applicable to the condition that the shape of the LOGO lamp is complicated; because the luminescence path is controllable, simulation analysis can be performed by optical CAE, so asto ensure the luminescence strength, light shape, luminescence angle and the like reach the vehicle standard level requirement.

Description

technical field [0001] The invention relates to a light guide type car-level LOGO lamp and a light guide method thereof, belonging to the technical field of automobile lamps. Background technique [0002] With the rapid development of the automobile industry, people have higher and higher requirements for energy saving, comfort, safety and aesthetics of automobiles. The design of car lights is not only a lighting or signal device, but also can effectively improve the aesthetics of automobiles. However, at this stage, the LOGO lights on the car usually use several LEDs to emit light directly and the outer translucent shell, so the luminous effect is difficult to achieve uniformity, especially the more complicated the shape of the LOGO lights, the worse the uniformity; in addition, due to the random arrangement of the LEDs The stability and translucent housing are difficult to CAE modeling, which makes it impossible to pass the optical CAE simulation analysis, so the luminous ...

Problems solved by technology

However, at this stage, the LOGO lights on the car usually use several LEDs to emit light directly and the outer translucent shell, so the luminous effect is difficult to achieve uniformity, especially the more complicated the shape of the LOGO lights, the worse the uniformity; in addition, due to the random arrangement of the LEDs It is difficult to model the translucent shell through CAE, which makes it impossible to pass the optical CAE simulation analysis, so the luminous intensity is also difficult to meet the regulatory requirements

Therefore, at present, domestic car companies do not define luminous LOGO as lights, and generally can only be used as car exterior decoration, for car logos, to enhance the appearance of cars, etc.
