Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a self-energyless irradiation device characterized by comprising means for condensing external light and means for converting the direction of the condensed external light into a desired direction. In particular, in automobiles, etc., lights are irradiated during the day using energy from an external source that is not installed in the vehicle body, to avoid over-discharging of the battery, and to make the presence of the vehicle more noticeable and help prevent accidents.
Also billboards and traffic lights.

This invention relates to a light device that uses no self-energy and is used during the day, which can also be used for road signs.

In recent years, with the rapid increase in the number of vehicles traveling on roads, the number of traffic accidents has also increased, and this has become a social problem, and there is an urgent need to establish countermeasures.

As part of this countermeasure, turning on the headlights of vehicles even during the daytime to make the presence of the vehicle more visible to other vehicles and pedestrians is effective in preventing accidents. In particular, consideration is being given to making it compulsory for motorcycles. This is already mandatory in Naori Nada.

However, turning on the headlights or taillights during the day using the vehicle's battery power source has the disadvantage that the battery may run out of power due to over-discharge of the battery.

Therefore, a separate type of daytime lighting device using a power source such as a solar battery has been considered as a daytime running light for accident prevention, but solar batteries are expensive.

It also has the disadvantage of being heavy.

In view of the above circumstances, the present invention not only improves traffic safety for pedestrians as well as vehicles, but also eliminates the need for separate power sources such as battery packs and solar cells, and provides an inexpensive and lightweight daytime running light for accident prevention. Suitable as well as advertising signs and traffic lights.

The purpose of the present invention is to provide an energy irradiation device that can be used in a wide range of applications such as road signs, boats, and aircraft.

The present invention will be described below based on embodiments shown in the accompanying drawings.

1 and 2 show an embodiment of the present invention.

The apparatus 1 is provided with a Fresnel lens 3 for condensing light on the top surface of a thin box 2, and an irradiation lens 4 is provided on both or one of the front and rear surfaces of the Il-shaped box 2. A reflector 5 made of a mirror, prism, etc. is provided inside the IF type box 2, and external light collected by the Fresnel lens 3 is reflected by the reflector 5 and powerfully irradiated through the front illumination lens 4. .

Here, if the area of the condensing lens is S and the area of the irradiation lens is S, then light amplified at S/s is irradiated. When the brightness of the environment is 2 and the brightness of the irradiation of the present invention is L.

Since the relationship is S / s x standing = L, the brightness L of the light device of the present invention is always brighter than the brightness of the environment.

Even on a perfectly sunny day, even brighter irradiation light can be obtained, and conversely, even if the visibility is reduced on a cloudy day, the brightness L of the light of the present invention will be proportionally smaller. , the brightness will always be greater than the cloudy brightness. In other words, it becomes a standing L.

FIG. 3 shows an embodiment in which the device 1' of the present invention, which has a front illumination lens 4 and a rear illumination red lens 6, is mounted on the roof of a four-wheeled vehicle C as an accident prevention light. An embodiment in which two pieces are placed on the left and right sides of the hood of a wheeled vehicle C is shown.

The devices 1, 1' are provided with a reflection lI5 approximately at the focal point of a condensing lens 3 such as a Fresnel lens.

External light collected by a condensing lens 3 passes through an irradiation lens 4 and is irradiated only to the front or to the front and back. In this case, the 0-reflector 5 having a chevron-shaped reflecting surface and dispersing light in the front-rear direction may be replaced with a prism. Alternatively, the lens 4.6 may be omitted and only the irradiation hole provided. Further, the rear lens 6 may be red or transparent and may include a red filter.

The lenses 4 and 6 may be Fresnel lenses.

In addition, illumination lights may be provided on both sides of the box 2 in addition to the front and rear to draw attention to both sides of the vehicle C. In this case, a reflector having four reflective surfaces that reflects the light in the front, rear, left, and right directions may be used. In the case of a device equipped with a plurality of condensing lenses, a reflector that reflects the light to both sides may be incorporated into some of the condensing lenses.

It goes without saying that the light devices 1 and 1' are applicable not only to four-wheeled vehicles but also to motorcycles, other vehicles such as buses and trucks, and Bonito aircraft.

FIG. 5 shows an embodiment in which the device of the present invention is applied to a billboard or display. This advertising tower 7 has the light device 1 on the top surface.
．． A Fresnel lens 3 similar to 1' is provided, and the outside light collected by the Fresnel lens 3 is reflected at right angles by a reflector provided inside the advertising tower 7 and irradiated to the eyes.

Signals and road signs are configured in almost the same way, and signal lights 9
Make letters etc. shine.

As described above, according to the present invention, the lamp is illuminated without energy by external light such as sunlight during the daytime, and can be used in billboards, traffic lights, road signs, automobiles, and other places where ring-opening energy is difficult to replenish. Furthermore, the device of the present invention is compact because it does not rely on heavy and expensive energy converters such as solar cells.
It also has excellent effects such as being inexpensive.

In addition, in contrast to normal lighting powered by battery power, etc., which is dim and inconspicuous under bright daylight due to the surrounding brightness, the light device according to the present invention accumulates the density of external light per unit area and is proportional to the external light. Since it is possible to obtain illumination light brighter than this, when the outside world is sunny and bright, it is even brighter, and even when it is cloudy and dark, it automatically follows the illuminance of the outside world and is relatively brighter than the outside world. Because it maintains the brightness.

It has the characteristic of always being bright and conspicuous.

As described above, the device of the present invention is an epoch-making invention that can make vehicles, ships, billboards, traffic lights, signs, etc. shine brighter than their surroundings without using their own power supply, since it does not require its own energy. be.
