Problems solved by technology

These patents are interesting, but only deal with the blinding effect ultimately produced by the lights of vehicles traveling in the opposite direction when driving at night
[0009] Any expert in this field will note that the devices described in the aforementioned patents are unlikely to effectively address the problem of reduced visibility caused by dioptric Halos, glare, distorted images, faded, flared, out-of-focus images, etc.
These patents only concern headlights for vehicles traveling in opposite directions at night

example 1

[0043] As a source of diffuse light emission, an LED lamp of a commercial type (Galaxy Link Industrial Co., Ltd.) that can be found on the market is used, the size of which is 12 cm wide and 24 cm long. Considering the size (width and length) of the lamp and the size of the driver's seat, the lamp is installed on the base structure of the roof of the vehicle. With five modules arranged consecutively without any intervals between the five modules, the five modules can be opened independently.

[0044] Lights mounted in this manner induce pupillary constriction without blinding the driver (4) of the vehicle. To do this, a power of 14 watts and a current of 1.2 amperes are set, and the following lighting conditions of the lamp are set: brightness of 2810 lux (lux) and color temperature of 7000°K. The color temperature of the light source (spectral composition) can be adjusted using a regulator (8) designed for this purpose, of the type that can be found on the market (Grasslin b...

example 2

[0046] Example 2 is carried out in the same way as described in Example 1, except that the light is mounted on the roof of the vehicle with a movement system fastened to the top, the movement system comprising a system of rails (6) and hooks , the rails and hooks are similar to those used to move the front seats of a car and adjust the position of the occupant of the seats.

example 3

[0048] Example 3 is implemented in the same manner as in Example 1, except that an optical filter (9) with a commercial type (Rosco brand) that can be found on the market is added, using an optical filter (9) that can be used at 380nm Adjust the spectral composition of light between wavelengths up to 500nm.

[0049] Power, current, brightness, and spectral composition can be varied, increasing color temperature with a greater proportion of shorter wavelengths. In order not to cause damage to the nervous system, changes in the spectral composition of the diffuse light (5) are always carried out within a safe range that protects the structure and function of the human retina from phototoxic light effects, which will depend on the stimulus Vary with time and composition.

Abstract

This invention relates to a device for diffused lighting for vehicle interiors that includes one or more light sources and that is located outside the field of vision of the driver of the vehicle. Drivers, especially following refractive surgery, manifest debilitating effects and symptoms of dazzling. The mioisis caused by the diffused light of this invention improves the driver's visual performance, in terms of quality of vision.

Description

technical field [0001] The invention is included in the design and construction of those parts of the vehicle related to driving safety and comfort. The present invention relates to interior lighting of vehicles and, more particularly, to setting optimum interior lighting conditions for vehicles in order to increase safety while driving, especially for drivers who have undergone refractive eye surgery. Background technique [0002] Because many commutes for work or play occur at night or in low-light conditions, vision in these environments is a very important topic in today's society. Many people experience severe difficulty driving at night or performing tasks in low lighting conditions (mesopic conditions), even though they do not experience any vision problems when in photopic lighting conditions (daylight). One of the most common causes of these difficulties is night-time myopia. Night-time myopia is characterized by difficulty focusing images in low-light conditions....
