[0015] As shown in Figure 1 And 2 An LED lighting optical anti-collision lamp, including base and lampshade 23 covered on the upper surface of the base, located at the center of the upper surface of the base, provided with aluminum substrate 11, located at the center of the aluminum substrate 11, upward and outward extending provided with curved surface setting reflector 22. Located at the outer periphery of reflector 22, the surface of aluminum substrate 11 is provided with arrayed LED light source 21. Located at the outer periphery of aluminum substrate 11, the upper surface of the base is sequentially provided with two annular optical assemblies.
[0016] The components will be described in detail as follows:
[0017] 1, design reflector 22
[0018] On the upper surface of the same aluminum substrate 11, the LED light source 21 is arranged in annular array, then the optical design software is used to design the cross-sectional profile line of the mirror optical reflector with the annular arrayed LED light source 21 as the optical focal point, and the mirror reflecting integrated optical reflecting surface is formed by rotating scanning around the center axis of the annular array of the LED light source 21 with the optical cross-sectional profile line as the reference. In the above design process, the light intensity spatial distribution required by the LED anti-collision lamp lighting standard is used as the reference, and the light energy of the LED is reflected and focused in a smaller angle space range.
[0019] 2. Designing the first and second diffuse reflection surfaces 12 and 13 of the optical assembly
[0020] Based on the optical rotation axis of the reflector 22, the first and second diffuse reflection surfaces 12 and 13 are designed by optical simulation software, and the space direction of the normal line of the first and second diffuse reflection surfaces 12 and 13 is taken as a design variable to reflect the light energy emitted by the diffuse reflection surfaces, and the part of the light energy is designed to be projected into a larger angle space range. The optical assembly to which the first and second diffuse reflection surfaces 12 and 13 belong can be but is not limited to a lamp structure assembly, and the annular first and second diffuse reflection surfaces 12 and 13 are two independent or continuous surfaces, and the number of surfaces can be but is not limited to two. Among the two diffuse reflection surfaces, the horizontal height of the second diffuse reflection surface 13 is lower than that of the first diffuse reflection surface 12, so as to realize diffuse reflection of scattered light reflected at different angles and improve the utilization rate of the scattered light.
[0021] The specific content of the utility model is:
[0022] As shown in Figure 1 , the reflecting surface of the reflector 22 is a mirror surface, the two optical assemblies are the first and second diffuse reflection surfaces 12 and 13 respectively, and the reflector 22 directly reflects the light source energy of the array distributed LED on the aluminum substrate 11 for the first time. In the implementation process of the patent technology, by adjusting the curvature of the reflecting surface of the reflector 22 and the spatial relative position parameters of the LED light source 21, the optimization of the spatial light intensity distribution of the LED light energy can be realized.
[0023] The light energy directly reflected by the reflector 22 for the first time is divided into two parts in the process of passing through the two optical interfaces of the lampshade 23 based on the direct transmission of light and the interface Fresnel reflection effect of the lampshade. The first part is directly emitted to the outside space of the lamp cavity, and the part of the light directly transmitted to the outside space of the lamp cavity accounts for most of the LED light energy. The second part of the light energy forms stray light at the two optical interface positions of the lampshade 23 due to the Fresnel reflection effect of the light and the optical interface of the lampshade 23, and most of the stray light is projected to the first and second diffuse reflection surfaces 12 and 13. The stray light formed by the Fresnel reflection is transmitted to the outside space of the lamp cavity again through the diffuse reflection surface of the lampshade 23.
[0024] According to the LED lighting optical anti-collision lamp, light energy emitted by the LED light source 21 is divided into the above two parts of light energy, and the first part and the second part of light energy are both transmitted from the inside of the lamp cavity to the outside space of the lamp cavity through the same lampshade 23. By adjusting the curvature of the reflector 22, the spatial position of the LED, the normal spatial direction of the surface of the first diffuse reflection surface 12 and the second diffuse reflection surface 13, the optimization of the light intensity spatial distribution of the anti-collision lamp can be realized. Among them, the base body of the first diffuse reflection surface 12 and the second diffuse reflection surface 13 can be part of the optical mechanical structure, and only the outer surface thereof is designed as part of the optical system.
[0025] The utility model discloses a structure member outer surface is designed as diffuse reflection optical surface, and the diffuse reflection optical surface can be two but not limited to two, and the spatial normal direction of each diffuse reflection optical surface can be used as the distribution design variable of the optimized anti-collision lamp optical system.
[0026] The above is only the preferred embodiment of the utility model, and does not have any limiting effect on the utility model. Any person skilled in the art, without departing from the scope of the technical scheme of the utility model, makes any form of equivalent replacement or modification of the technical scheme and technical content disclosed by the utility model, and the change still belongs to the protection scope of the utility model.
