Embodiment Construction

[0020] The strip-shaped free-form surface LED lamp optical mask of the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0021] The strip-shaped free-form surface LED lamp optical mask of the present invention is formed by splicing several optical mask units.

[0022] Such as Figure 1a ~ Figure 1d As shown, the optical mask unit is formed by splicing one or more free-form polyhedrons front to back and at different angles.

[0023] Such as Figure 2a~Figure 2c As shown, the surface parameters of the free-form surface polyhedron are calculated according to the specific requirements of different lamps, and the calculation method of the surface parameters is common knowledge of many people in the field of lamp lighting. In the free-form polyhedron in this embodiment, the upper end surface is a free-form surface, which is arched; the lower end surface is a bottom surface; the free-form surface and the bottom surf...

Abstract

The invention belongs to the technical field of lamp covers and particularly relates to a banded LED lamp optical cover with a free-form surface. The banded LED lamp optical cover with the free-form surface is formed by jointing a plurality of optical cover units; each optical cover unit is formed by jointing one or multiple free-form surface polyhedrons at different angles. The banded LED lamp optical cover with the free-form surface has the advantages that flux of LED light sources can be reasonably allocated, flux availability is improved, and LED lamp lighting quality is improved.

Description

technical field [0001] The invention belongs to the technical field of lamp masks, and in particular relates to a band-shaped free-form surface LED lamp optical mask. Background technique [0002] A light emitting diode (Light Emitting Diode, LED) is a semiconductor diode that can emit light, and is a light emitting device that directly converts electrical energy into light and radiation energy. Light-emitting diodes have many advantages: low operating voltage, luminous efficiency, stable performance, long life, strong vibration resistance, light weight, and small size. In recent years, while LED has solved all color display problems, white LED has reached more than 100lm / W, and has all the conditions for application in automotive lighting, traffic signal display, LED display and daily lighting. At present, LEDs have been widely used in traffic lights, liquid crystal display back lamps, automotive lighting and daily lighting and other fields. But LED is not equal to LED la...
