As shown in fig. 1-2, the starry sky pattern rear position lamp of the invention comprises an LED light source 1, a circuit board assembly 2, a mounting bracket 3, a starry sky pattern additional face shield 4, a decorative ring 5, an outer face shield 6 and a shell 7.
The LED light source 1 is arranged on the circuit board assembly 2; the circuit board assembly 2 is used for supplying power to the LED light source 1 and driving the LED light source to be lightened; the circuit board assembly 2 and the decorative ring 5 are fixed on the mounting bracket 3; the starry sky pattern additional face mask 4 is fixed with a decorative ring 5 through a screw structure; the mounting bracket 3 is fixed with the shell 7, and the shell 7 is fixed with the welding outer mask 6; the light emitted by the LED light source 1 is adjusted through the starry sky pattern additional mask 4, and then light distribution is realized through the outer mask 6.
The light emitted by the LED light source 1 directly irradiates the starry sky pattern additional face mask 4, is refracted through the polygonal patterns on the starry sky pattern additional face mask 4 to form a light type meeting the light distribution requirement of the position lamp, and is emitted through the starry sky pattern additional face mask 4 and the outer face mask 6 in sequence.
The starry sky pattern additional face mask 4 is made of transparent materials and is provided with a random starry sky pattern structure on the surface, a plurality of random points are established through software, then the size of the random surface is controlled according to the discrete degree of the points, three-dimensional operation is conducted on each point through an autonomous research and development tool to obtain a specific surface, and the size, the angle and the number of edge surfaces of each pattern have certain difference, so that the uniqueness of each pattern is realized.
Specifically, the transparent material is PC, the material brand is AL2647, random starry sky patterns are generated on the surface of the material, so that light is irregularly scattered in the material, and starry sky light-emitting effects observed at different angles are realized.
Compared with the scheme that the additional face mask is made of scattering materials, the starry sky pattern rear position lamp is difficult to meet the position lamp regulation requirements, the stereoscopic surface structure of the starry sky pattern has a scattering effect on light, the utilization rate of the light is reduced, and meanwhile, the additional face mask of the position lamp is made of transparent materials, so that light loss can be effectively reduced (compared with the scattering materials). Therefore, the generation and the structural design of the starry sky patterns need to be optimized and adjusted for multiple times so as to meet the light distribution requirement of the position lamp. Because the starry sky pattern effect has low requirement on the uniformity of light emission, the LED spacing can be properly increased when the LEDs are arranged and arranged, and the purpose of designing the cost is achieved.
