Description

Warning light optical structure

This creation is about an optical structure of a warning light, especially a warning light structure that can expand the illumination light field to create a creative application.

According to the warning lights, they are usually installed in vehicles with special tasks, such as ambulances, fire engines, guard cars, engineering vehicles or ambulances, or for duty personnel in some special climates or occasions, such as night traffic accidents. When dealing with car accidents, firefighters' night disaster rescue, mountain rescue, heavy fog, heavy rain, typhoon, earthquake, power outage or night emergency rescue, the scene needs to be illuminated for rescue.

However, general warning lights use high-power light-emitting components, mainly to produce high-illumination light, but because the light-emitting components are mainly based on LED lights, and their LED lights have many advantages, but because the LED lights are direct Light, therefore, makes its existing warning luminaires somewhat missing, as described below:

1. The optical field is insufficient. Because the LED light is direct light, the light on both sides or the surrounding area is insufficient.

2. If you increase the LED light and change the display angle, it will cause cost problems, power and heat dissipation problems.

In view of the above-mentioned shortcomings, there is a creative design in this respect. For example, the creator has previously applied for Announcement No. M341281, "Optical Lampshade Set with Lens Positioning Function", or a warning light structure of Announcement No. M354129. A light-reducing body, a light-emitting body, a substrate and a heat-dissipating plate are sequentially disposed in the lampshade; wherein: the lampshade is formed with a light-emitting surface of a wavy line on the inner bottom portion, and the inner peripheral wall of the lampshade is formed into a class edge, and is in the lampshade The wall is located above the edge of the class, and the insert block is protruded, and the inner wall of the lampshade is located at a position below the class edge, and a positioning column is protruded; the light-reducing body forms a wave-like grain on the end surface thereof to be wavy with the inner side of the lampshade. The light-emitting surface is correspondingly positioned, and a hole is formed at the other end of the light-reducing body; the light-emitting body is disposed in the hole of the light-receiving body and is assembled with the substrate; the substrate is disposed on the inner wall of the lamp cover The heat dissipating plate is disposed on the substrate, and the peripheral side thereof is formed with an inclined edge to be fixed between the edge of the lamp cover and the block. The refractor design of the above structure is still unable to effectively diffuse the light field.

The reason is that, in view of this, the creators have been adhering to the rich experience in design, development and actual production of the relevant industries for many years, and have researched and improved the existing structures and defects to provide an optical structure of warning lights for the purpose of achieving better practical value. By.

The main purpose of the optical structure of the warning light of the present invention is to improve the lack of prior art optical domain deficiency, thereby forming an annular expanded light shape by expanding the side optical elements and guiding the light, thereby achieving the effect of expanding the illumination range. For the purpose.

The purpose and function of the optical structure of the creation warning light is achieved by the following technologies:
The main component is provided with a light-emitting component, and a light cover is disposed on the base and covers the light-emitting component. The main optical component and the side optical component are disposed between the light-emitting component and the light cover. One end surface is provided with a hole corresponding to the light-emitting element, and the first end surface to the second end surface are expanded side walls, and a groove is formed on the second end surface, and the circumference of the groove is formed with a light guiding ring surface; thereby, the utilization side The diverging light guide surface of the optical element directs light out to form an annular expanded light shape to achieve an optical domain function that increases the illumination of the warning light.
