deep sense light emitting device

Abstract

The invention discloses a light-emitting device with a sense of depth, which comprises a lampshade, a lamp housing, a decorative ring and LEDs. The LED is installed in the cavity of the outer lampshade and the lamp housing, the inner surface of the inner lampshade is provided with a light-splitting film, the outer surface of the decorative ring is a reflective surface, and the light-splitting film and the The reflective surfaces are arranged at relative intervals, the LED is located next to the bezel, the LED emits light toward the light splitting film, part of the light passes through the light splitting film and the inner lampshade, and part of the light is emitted by the light splitting film. The film reflects and shoots to the reflective surface, and the light splitting film and the reflective surface alternately reflect light as above. The present invention achieves a profound visual effect through alternate times of specular reflection between the light splitting film and the reflective surface. This application only needs at least one set of LEDs, which greatly saves the cost; and the LEDs are easy to mass-produce and the cost is low.

Description

technical field [0001] The invention relates to the technical field of optical devices, in particular to a light-emitting device with a sense of depth. Background technique [0002] Car lights, as the most active finishing touch of the vehicle's exterior decoration, are no longer limited to their functionality. Whether their appearance is beautiful or not is becoming more and more important. Creating a sense of depth is one of the trends in headlight styling. Obtaining a sense of depth often requires heavy overlapping of light-emitting units in the depth direction, resulting in increased costs and limited effect of depth. [0003] Existing solution 1: use OLED multi-light-emitting surface structure, the current OLED cost is high (the price is dozens of times that of ordinary light sources), and the production capacity cannot meet mass production, and it does not have the feasibility of mass production.

Obtaining a sense of depth often requires heavy overlapping of light-emitting units in the depth direction, resulting in increased costs and limited effect of depth

[0003] Existing solution 1: use OLED multi-light-emitting surface structure, the current OLED cost is high (the price is dozens of times that of ordinary light sources), and the production capacity cannot meet mass production, and it does not have the feasibility of mass production

[0004] Existing solution 2: Step-shaped two-color injection molding solution is often limited by the depth of body sheet metal stamping. The depth cannot be made too deep, only a few steps can be made, and the sense of depth in the shape is limited.

In addition, two-color injection molding needs to share the gate, and the same color resin needs to be connected, which brings restrictions to the shape

And the number of LED light sources increases, and the cost doubles
