Abstract
The invention belongs to the technical field of an optical mask for an LED (Light Emitting Diode) lamp, and particularly relates to an optical mask with scute polyhedrons for an LED lamp. The optical mask with scute polyhedrons for the LED lamp is formed by closely arranging a plurality of optical mask units (1), the bottom surface of each optical mask unit (1) is in a polygon shape, and the upper surface of each optical mask unit (1) is in a scute shape; the scute upper surface of each optical mask unit (1) is composed of one or a plurality of rows of scute polyhedrons, and different angles are formed between the scute polyhedrons and the bottom surfaces of the optical mask units (1), so that the upper surfaces of the scute-shaped optical masks are in arc shapes. According to the different distribution requirements of different needed luminous flux in practical use, the optical mask for the LED lamp is made from transparent optical glass, polycarbonate or other optical materials, and the orientation angles of all surfaces of the optical mask are different due to the different physical properties of materials. According to the optical mask with scute polyhedrons for the LED lamp the luminous flux of the LED lamp can be distributed well, so that the luminous flux of the LED lamp can be reasonably distributed, and the lighting quality of the LED lamp can be significantly prompted.
Description
Technical field
The invention belongs to the optical mask structure field that relates to LED light fixture, relate in particular to a kind of scale and shell Polyhedral LED lamp optical mask.
Background technology
Along with the arriving in the 4th illumination-semiconductor lighting epoch in generation, light efficiency, the power of light emitting diode (Light EmittingDiode is called for short LED) improve constantly.The features such as LED is low with its operating voltage, luminous efficiency is high, stable performance, life-span length, shock resistance, vibration resistance is strong, lightweight, monochromaticjty is good, colour rendering is good, application is more and more wider.LED has been widely used in the fields such as liquid crystal backlight, normal lighting, traffic lights, automotive lighting and street lighting.Because LED itself is the spot light of small size, can not directly use as illuminations.For meeting the requirement of the performances such as the light spot shape for light fixture, light distribution, the uniformity in practical application, need to after LED encapsulation, collect and be combined with the optical mask through optical design.Existing optical design and the improvement thereof that LED light fixture optical mask is carried out of existing lamp illuminating system, prior art is mainly utilized reflector or lens to realize light fixture hot spot to distribute and inhomogeneity control, but still has luminous flux utilization rate and in the poor problem of the reasonable layout of certain space.Therefore, need to provide a kind of novel LED light fixture optical mask.
Summary of the invention
The object of the invention is to overcome the light distribution and the inhomogeneity problem that in prior art, exist, provide a kind of and can obtain the reasonable layout of good LED light source luminous flux in space, improve the scale and shell Polyhedral LED lamp optical mask of luminous flux utilization rate simultaneously, improve the quality of LED light fixture.
The technical solution used in the present invention is: a kind of scale and shell Polyhedral LED lamp optical mask, is formed by multiple optical masks unit close-packed arrays;
