Description

An LED reflective light distribution and exit structure and a light-emitting road stud containing the structure

technical field

The utility model relates to the field of light-emitting equipment, in particular to an LED reflection light distribution and outgoing structure and a light-emitting road stud containing the structure.

technical background

Light-emitting equipment with the function of light-emitting induction or auxiliary lighting includes buried lights, light-emitting road studs, solar-powered floor lights, delineators, etc., with motor vehicle drivers or pedestrians as the main service objects. As a light-emitting device that is mainly used in public places, compared with ordinary light-emitting devices, not only its light-emitting performance should be considered, but also structural strength requirements such as compression resistance and impact resistance and waterproof requirements, as well as some safety regulations. Therefore, for these light-emitting devices The comprehensive performance requirements of the equipment are more demanding. Among them, the most widely used luminous road studs are represented.

The light exit structure mainly includes two types of exit structures: LED horizontal exit or oblique upward exit at a certain elevation angle.

The horizontal emission type structure has a good luminous effect, but due to the restrictions on the size (width, length or height, etc.) of road traffic safety equipment in some traffic regulations, the highest point of the raised luminous road stud shall not be 25mm higher than the road surface and buried in the ground. The height of the light-emitting road stud is generally not more than 10mm above the road surface, and it is best to control it below 8mm, which is not easy to flatten and intensify the product, especially the light-emitting equipment represented by the buried light-emitting road stud with limited height.

In contrast to the oblique upward emission type structure, for example, the main luminous direction of the LED of the existing buried light emitting road stud emits light obliquely upward (side up) toward the light emitting surface, and the emitted light is refracted and transmitted out. Although the structure is more compact, its main There are the following major flaws:

1. The components and structures of the existing oblique upward exit structure represented by light-emitting road studs have not reached the optimal configuration, and the optical path design is also unreasonable, resulting in the proportion of light energy in the lateral (horizontal direction) of the outgoing light. Low, resulting in a short sight distance, poor lighting effect on the driver, and can only meet the basic needs of conventional roads. With the implementation of road lighting projects, the improvement of road speed limits and the proposal of unlimited speed highways, a longer luminous sight distance is required. Due to the revised road lighting specifications, the illumination conditions on high-grade roads and urban arterial roads have been increased to between 20-30Lux. In addition, with the development of lighting technology, the brightness of vehicle lights is also increasing. Therefore, the existing light-emitting road studs have the limitations of low horizontal light-emitting brightness and poor identification, which can no longer meet the new road development status.

2. The existing oblique upward exit structure has too strong oblique upward light (backward to the main traveling direction of road vehicles), which is very dazzling, and will cause light interference to car drivers or pedestrians who are facing away, and become a traffic hazard. .

Third, in order to increase the proportion of light intensity in the horizontal direction of the outgoing light, the internal optical structure is very complex, resulting in high manufacturing costs and high failure rates. Especially under the size constraints of traffic regulations, it is not conducive to flattening and intensification.

Fourth, the existing light output structure of light-emitting equipment represented by road studs is difficult to accurately allocate the spatial light field distribution, and sometimes there is too much stray light.

To sum up, the existing road traffic lighting equipment has no optimal configuration between components and structures.

, the optical path design is unreasonable, resulting in unreasonable light field distribution of the exit light of the road stud, resulting in insufficient lateral or horizontal luminous concentration, poor remote luminous effect, short luminous sight distance, low long-distance recognition, and short-range luminescence It is also easy to cause light interference, which is not conducive to the flattening and intensification of equipment within the size limit of the existing traffic regulations, and has become an urgent problem to be solved in the industry. Higher requirements are put forward for road guidance safety products, and the demand for road traffic lighting equipment with good remote lighting effect and easy to flatten and intensify is increasingly urgent.

Utility model content

The technical problem to be solved by the present utility model is to provide a light-emitting matching and optical path transmission and optical structure parameters that match each other and form a specific optical structure in combination with the specular reflection layer, so as to achieve the main output of the emitted light in the horizontal direction, and the auxiliary in the upward direction. The purpose of optimizing the distribution of the spatial light field with high overall output efficiency of the emitted light, and achieving physical indicators such as structural strength and waterproof function. The lateral (horizontal) luminous brightness is greatly improved within the range of height difference, the light field distribution and the light output ratio in each direction can be accurately allocated, the output light field distribution is more optimized, the luminous viewing distance is long, the short-range glare is less, and the structure It is compact and has high compressive strength, which can meet the requirements of light-emitting equipment limited by size and other specifications. It is conducive to flattening and intensive production, and is especially suitable for light-emitting equipment represented by light-emitting road studs. It can especially meet the requirements of road lighting projects. The implementation and the improvement of road speed limit and the proposal of unlimited speed road put forward new requirements for road traffic lighting equipment represented by road studs, which still have high recognition under the condition of 30LUX illumination. Due to the high proportion of light energy in the lateral (horizontal direction) of the emitted light, it can greatly improve the lateral (horizontal direction) luminous brightness, so that the luminous viewing distance is long, and more eye-catching light spots can be seen in the long-distance horizontal direction. , so the recognition is very high, which is beneficial to the driving driver, and the upward light intensity accounts for a small proportion, so the short-range lighting is not dazzling, which is beneficial to pedestrians, and the lighting effect of drivers and pedestrians can be optimized.

Starting from optics, LED device characteristics, structural mechanics, molding technology (especially injection molding), visual psychology, traffic design specifications, road lighting specifications, etc., the utility model creatively proposes a more suitable road stud as a representative The LED reflection light distribution and exit structure of road traffic lighting equipment and the light-emitting equipment with greatly improved luminous performance based on the advantages of the light exit structure, the main core creativity lies in:

Using the luminous characteristics of LED devices, through luminescence matching, optical design of the optical path and optical structure parameters, and combined with the specular reflection layer, the LED reflection light distribution and output structure is innovatively designed, especially in the reflective surface, light incident surface, The optical parameters such as the light-emitting surface and its angle, height, width, and sidewall thickness between the light-incident surface and the light-emitting surface are matched with the physical structure. To achieve the expected purpose of the required design, and make it convenient for process molding and production implementation; use an open light emitting groove, and set a specular reflection layer on the inner side wall away from the light emitting surface, and make the main direction of the LED light emitting body light toward the The above-mentioned reflective layer is incident at an acute angle of a certain angle. According to the reflection theorem of light and the refraction theorem n1sinα1=n2sinα2, most of the light emitted by the LED illuminant (light within the half-value angle) is projected on the reflective layer and specularly reflected, and is reflected in the mirror. A very bright reflection spot is generated on the reflective surface (1a) (the transparent surface without the specular reflection layer has only partial reflection, and part of the light has been refracted and transmitted from the back), and most of the reflected light passes through the light-incident surface and the light-exiting surface. After the surface is refracted, it can be emitted in the horizontal direction, and while part of the light is refracted on the light incident surface (1b), part of the light is reflected, so the light incident surface (1b) and the specular reflection layer ( 3) There are also secondary reflections between them, which further improves the light output efficiency. The lateral (horizontal) light energy of the outgoing light accounts for a high proportion, which can greatly improve the lateral (horizontal) luminous brightness, so that the luminous sight distance In the long-distance horizontal direction, a more eye-catching outgoing spot can be seen on the light-emitting surface (1c) (under the illumination conditions of 20LUX to 30LUX, when the LED light-emitting body emits light, people still remain on the light-emitting surface (1c) in the horizontal direction. It can be seen that the striking outgoing light spot in the LED reflection light distribution outgoing structure has a high degree of identification, while the conventional light outgoing structure that does not meet the light outgoing conditions of the present utility model can only see the outgoing light spot with a low degree of identification), so the identification The light intensity is very high, which is beneficial to driving drivers, and the proportion of upward light intensity is small, so the short-range lighting is not dazzling, which is beneficial to pedestrians, and the lighting effect for both drivers and pedestrians can be optimized, and the structure is compact, which is conducive to flattening and intensification Production.

The main advantage of this utility model is:

1. Compared with the inverted V-shaped LED reflection light distribution and exit structure with no specular reflection layer (3) or without parameter optimization and matching, and the light-emitting equipment represented by light-emitting road spikes containing this structure, the LED's The main direction of light emission is mainly towards the direction of the exit surface, there is at most partial partial reflection, and there is no specular reflection, so there is no very bright reflection spot on the inner wall (because there is only partial reflection, and part of the light has been refracted and transmitted from the back), There is also no very bright outgoing spot on the light-emitting surface, resulting in a low proportion of light energy in the lateral (horizontal) direction of the outgoing light, and low lateral luminous brightness, resulting in a short viewing distance and poor lighting effect on car drivers or pedestrians. , there are limitations in road use; and the LED reflection light distribution and output structure of the present invention with optical path design and light energy matching and the light-emitting equipment represented by the light-emitting road studs containing the structure are similar to the vertical section and have an inverted V shape. A specular reflective layer is arranged on the inclined surface away from the light emitting surface, and the main direction of light emitted by the LED illuminator after being condensed by the condensing lens is directed toward the above-mentioned reflective layer, so there is a very bright light on the reflective surface. There are also very bright outgoing light spots on the light-emitting surface, which can realize that the lateral (horizontal) luminous intensity is 3 to 10 times that of the former, which can greatly improve the lateral (horizontal) luminous effect. Moreover, the proportion of light output can be accurately configured according to actual needs through the proportion of reflective area, so as to manufacture light-emitting devices with better performance, which can meet the requirements of road traffic due to the implementation of road lighting projects, the improvement of road speed limits and the proposal of unlimited speed highways. New requirements for lighting fixtures.

2. Compared with the vertical section without the specular reflection layer (3) or without parameter optimization and matching, the vertical section is an inverted V-shaped LED reflection light distribution and exit structure and the light-emitting equipment represented by the light-emitting road stud containing this structure. The light emission within a certain angle range in the vertical direction (normal direction) of the inner side wall away from the light-emitting surface in the inverted V-shaped light-emitting groove is too strong and very dazzling, and it will cause light interference to the driver or pedestrians who are facing away from the light. However, the LED reflective light distribution output structure of the present invention, which is designed with light path and light energy matching, and the light-emitting equipment represented by the light-emitting road studs containing the structure, has more eye-catching light spots in the horizontal direction, and is more recognizable to the driving driver. High, and it can reduce the light interference of pedestrians, and the lighting effect for drivers and pedestrians can be optimized.

3. Compared with the inverted V-shaped LED reflection light distribution and exit structure with no specular reflection layer (3) or without parameter optimization and matching, and the light-emitting equipment represented by light-emitting road studs containing this structure, in order to improve the output The proportion of light intensity in the lateral direction of the incident light is high, and its internal optical structure is very complex, resulting in high manufacturing cost and high failure rate. Especially under the size limit of traffic regulations, it is not conducive to flattening and intensification. The optical structure that matches the light energy is more compact, which is conducive to the flattening and intensification of the product, and can be used as the local structure of traffic signs such as road spikes or delineators.

4. The LED reflective light distribution output structure of the present invention and the light-emitting equipment represented by the light-emitting road studs containing the structure can not only be used for light-emitting road studs, but also can be used for light-emitting delineators, etc. The effect is better, it can improve traffic safety efficiency and reduce traffic safety accidents, and has very high application value and social benefits. Compared with the existing similar products that make up for their defects by increasing power, it has higher economic value.
