Automobile logo capable of emitting light

Abstract

The invention relates to an automobile logo capable of emitting light. The automobile logo comprises a base box, a PCB arranged in the base box, a light guide plate and a reflecting film clamped between the PCB and the light guide plate. The lampshade is fixedly connected to the opening part of the base box; a logo pattern area is arranged on the lampshade; eight LED lamp beads are arranged on the edge close to the periphery of the PCB, and eight avoiding holes are formed in the edge close to the periphery of the light guide plate. The eight LED lamp beads on the PCB respectively penetrate through the reflecting film, are in one-to-one correspondence with the eight avoiding holes in the light guide plate and protrude into the avoiding holes; the height d1 of the avoiding hole is greater than the height d2 of the LED lamp bead; the light guide plate is provided with a light-emitting area corresponding to the logo pattern area on the lampshade, and pentahedral cavity structures arranged in a dot-matrix mode are carved in the light-emitting area. The LED lamp is high and uniform in luminous intensity, small in number of used LED lamp beads, low in manufacturing cost and wide in application range.

Description

technical field [0001] The invention relates to a car logo, in particular to a luminous car logo. Background technique [0002] With the development of automobile technology, the electrification of traditional parts and intelligent interaction between automobiles and people has become the development trend of future automobiles. For example, the car logo, the traditional logo is only used as the vehicle brand logo of the OEM and has no other functions, and its function is single and boring. However, the luminous logo can not only represent the brand identity of the OEM, but also endow the logo with the characteristics of luminescence. Through program control, the logo can interact with people, realize the role of welcoming guests in the whole vehicle, and increase the driver's sense of user experience and sense of technology. . [0003] At present, there are two types of lampshades for automotive luminous logos on the market: transparent lampshades and electroplating effec...

AI Technical Summary

Problems solved by technology

[0007] Due to the light intensity, the diffuse reflection lighting method is mainly used in transparent lampshades. This lighting method uses fewer LED beads and lower cost, but the luminous intensity is low and the luminous effect is poor.

[0008] LED light group arrangement and LED light strip light are mainly used in electroplating effect lampshades, which have uniform light and high luminous intensity, but the number of LED lights in these two ways is relatively large, and the price of a single component is relatively high, and the LED The increase in the number also increases the heat dissipation space requirements of the luminous logo, which will increase the thickness of the entire luminous logo component
