Background technique

With the advent of the fourth-generation lighting—semiconductor lighting era, the light efficiency and power of light-emitting diodes (Light Emitting Diode, referred to as LED) continue to increase. Due to its low operating voltage, high luminous efficiency, stable performance, long life, strong impact resistance, strong vibration resistance, light weight, good monochromaticity, and good color rendering, LEDs are used in more and more fields. LED has been widely used in liquid crystal backlight, daily lighting, traffic lights, automotive lighting and street lighting and other fields. Since the LED itself is a small point light source, it cannot be directly used as a lighting tool. In order to meet the requirements of light spot shape, light intensity distribution, uniformity and other performance requirements of lamps in practical applications, it is necessary to collect LEDs after packaging and use them in combination with optically designed optical masks. The existing lamp lighting system has optical design and improvement on the optical mask of LED lamps. The existing technology mainly uses reflectors or lenses to control the distribution and uniformity of lamp spot, but there are still luminous flux utilization and in a certain space. The problem of poor reasonable distribution of . Therefore, it is necessary to provide a novel optical mask for LED lamps.

Contents of the invention

The purpose of the present invention is to overcome the problems of light intensity distribution and uniformity existing in the prior art, and provide a kind of scute polyhedron LED lamp optics that can obtain a good spatial distribution of the luminous flux of the LED light source and improve the utilization rate of the luminous flux. Masks to improve the quality of LED lamps.

The technical solution adopted in the present invention is: a squamous polyhedron LED lamp optical mask, which is formed by a plurality of optical mask units closely arranged;

The bottom surface shape of an optical mask unit is a triangle, a quadrangle, a pentagon, a hexagon, a decagon, a dodecagon or a combination thereof, and its upper surface is scale-shaped;

The scute-shaped upper surface of the optical mask unit is composed of one or more rows of scute polyhedrons, and each row of scute polyhedrons contains one or more scute polyhedrons with the same shape or multiple shapes matching;

The scale polyhedron is in the shape of a cube, cuboid, prism, pyramid, prism or other polyhedrons, and its base is triangular, quadrilateral, pentagonal, hexagonal, decagonal, dodecagonal or other polygonal, adjacent The scute polyhedron forms a gradual angle with the bottom surface of the optical mask unit, so that the scute-shaped upper surface of the optical mask is curved.

According to the different luminous flux distribution requirements for the actual use of the optical mask, the material of the optical mask of the LED lamp can be transparent optical glass, polycarbonate, polymethyl methacrylate or other optical materials, and the orientation angle of each surface on the optical mask depends on the material physics The nature is different, and it is calculated and determined according to the different distribution requirements of the luminous flux for actual use.

An LED lamp using the above-mentioned optical mask is composed of a bowl-shaped lens, an LED and an optical mask of a polyhedral LED lamp with scales. The LED is located in the bottom surface of the bowl-shaped lens and assembled coaxially with the lens. along the connection.

The lens in the LED lamp is a total reflection lens.

The technical effect of the invention is that the scale polyhedron LED lamp optical mask is combined with the lens and used in the LED lamp, which can distribute the LED luminous flux well, realize the reasonable distribution of the luminous flux of the LED lamp, and significantly improve the lighting quality of the LED lamp.
