Abstract
Description
Technology Field
[0001] The present invention relates to an intelligent long-type mood lamp for an electric vehicle door trim, characterized by comprising: a cover portion (110) having an inner space formed therein; a light guide (120) connected to an LED module (200) and irradiated with light while inserted into the inner space; and a lens molding portion (130) coupled to the upper part of the cover portion (110) to diffuse the light source of the light guide (120). Background Technology
[0002] Generally, a light-emitting diode (LED) is a semiconductor light-emitting device that emits light by passing an electric current through a compound such as gallium arsenide. It utilizes the pn junction structure of an m semiconductor to inject minority carriers (electrons or holes) and emits light through their recombination.
[0003] These LEDs have high conversion efficiency, so their power consumption is only 1 / 8 of that of a light bulb and 1 / 2 of that of a fluorescent lamp. Because they are small light sources, they can be miniaturized, thinned, and lightweight. They also generate less heat, have a longer lifespan than light bulbs, have a faster response speed (the time from when current flows until light is emitted), can be made in various shapes, and have semi-permanent lifespans and excellent economic advantages, so they are used in all industrial sectors where lighting is used, such as indoor and outdoor buildings and automobiles.
[0004] Meanwhile, mood lighting installed in the interior of a vehicle is one of the convenience features provided to offer a comfortable and pleasant ride to the driver and passengers while the vehicle is in operation.
[0005] There is a need for various technological developments for such mood lamps to enhance aesthetics by diffusing light through an LED light source to produce a soft effect, to ensure uniformity of light and various colors while being formed from a single light source, and to provide safer driving to passengers by linking with the vehicle's driving assistance functions.

FIG. 4 is an embodiment showing an intelligent long-type mood lamp for an electric vehicle door trim according to a preferred embodiment of the present invention illuminating in a specific color when a person or object is recognized by an external sensor of the electric vehicle. Specific details for implementing the invention
[0015] Hereinafter, an intelligent long-type mood lamp (100) for an electric vehicle door trim according to an embodiment of the present invention will be described in detail with reference to the attached drawings. First, it should be noted that in the drawings, identical components or parts are indicated by the same reference numerals as much as possible. In describing the present invention, specific descriptions regarding related known functions or configurations are omitted to avoid obscuring the gist of the present invention.
[0017] Referring to FIG. 2 or FIG. 3, an intelligent long-type mood lamp (100) for an electric vehicle door trim according to one embodiment of the present invention is largely composed of a cover part (110), a light guide (120), and a lens molding part (130).
[0019] First, the cover portion (110) will be described. As shown in FIG. 2 or FIG. 3, the cover portion (110) is a component in which the cross-section is formed in a “U” shape, the lens molding portion (130) described later is coupled to the upper part, and the light guide portion (120) described later is installed on the inner side, and an inner space into which the light guide portion (120) is inserted is formed on the inner side.
[0020] Meanwhile, a first optic element with a groove shape arranged at a predetermined interval may be further formed in the above internal space, and as a result, it is possible to change the light emission characteristics during the process in which the light source output from the LED module (200) emits light through the light guide part (120), thereby improving the uniformity of illumination.
[0022] Next, the light guide section (120) will be described. As shown in FIG. 3, the light guide section (120) is a component that is inserted into the inner space of the cover section (100) and connected to the LED module (200) to transmit a light source to the lens molding section (130). It is preferable that a plurality of second optic elements, like the first optic element, are arranged at predetermined intervals on the lower surface of the light guide section (120).
[0024] Next, the lens molding part (130) will be described. As shown in FIG. 2 or FIG. 3, the lens molding part (130) is a component that is coupled to the upper part of the cover part (110) to uniformly diffuse the light source of the light guide part (120), and can perform the role of at least diffusing, reflecting, refractioning, collimating, or diffracting the light source emitted from the light guide part (120), and may include a micro-lens array to improve the quality or effective amount of the radiation output, such as collection, condensing, collimation, or otherwise.
[0026] Meanwhile, the cover portion (110), the light guide (120), and the lens molding portion (130) are formed to be long in the horizontal direction of the door trim so as to be applicable to medium and large vehicles, and it is preferable that the total length be formed to be 700mm to 800mm.
[0028] In addition, the light guide (120) has a single light source of the LED module (200) applied to one side thereof, and the brightness uniformity is 80% or more, so that it can provide a comfortable and pleasant aesthetic sense to the passenger due to the continuous light emission effect.
[0030] Meanwhile, the above light guide (120) is linked with the external sensor, sensor module, and control module of the electric vehicle, and when a person or object is detected in the front, rear, or side of the vehicle (electric vehicle), it lights up in a specific color (red, etc.) to provide a warning signal to the occupant, thereby enabling the prevention of safety accidents that may occur when driving the vehicle (electric vehicle) or when an occupant exits the vehicle (electric vehicle).
[0031] At this time, when the light guide (120) is illuminated in a specific color (red, etc.) to provide a warning signal to the occupant, the light is repeatedly turned on and off for a set time through the control module and power module, thereby enabling a more intuitive signal notification.
[0033] Optimal embodiments have been disclosed in the drawings and specification. Specific terms have been used herein, but are used only for the purpose of describing the invention and are not intended to limit the meaning or the scope of the invention as described in the claims. Therefore, those skilled in the art will understand that various modifications and equivalent alternative embodiments are possible therefrom. Accordingly, the true technical scope of protection of the invention should be determined by the technical spirit of the appended claims. Explanation of the symbols
