Problems solved by technology

But LED is not equal to LED lamps. LED itself is a point light source. High-power LED brightness is too high to produce glare, so LED cannot be directly used in lighting fixtures.

Embodiment Construction

[0021] The optical mask of the conical LED lamp of the present invention will be described in detail below with reference to the drawings and embodiments.

[0022] like Figure 1a ~ Figure 1c As shown, the optical mask of the cone-shaped LED lamp of the present invention includes one or more optical mask units.

[0023] like Figure 2a~Figure 2c As shown, the optical mask unit includes: a cone and several circular frustums, the cones are stacked on the top, and the circular frustums are stacked upright under the cones according to the radius of the bottom surface from small to large; the bottom surface of the cone and the upper bottom surface of the adjacent circular frustum The radii are the same, and the lower bottom surface of each truncated cone has the same radius as the upper bottom surface of the truncated circular cone below it; for the cone and several circular truncated cones, the angles formed by the generatrix and the bottom surface are different.

Abstract

The invention belongs to the technical field of lamp masks, and particularly relates to a conical LED lamp optical mask which comprises one or multiple optical mask units. Each optical mask unit comprises a cone and a plurality of circular truncated cones, each cone is stacked at the top, the circular truncated cones are erected and stacked below the corresponding cone according to undersurface radius from small to big, the undersurface of each cone is identical with the upper undersurface of the circular truncated cone adjacent to the cone in radius, and the lower undersurface of each circular truncated cone is identical with the upper undersurface of the circular truncated cone below in radius. By the conical LED lamp optical mask, luminous flux of an LED light source can be reasonably distributed, so that luminous flux utilization rate is increased, and lighting quality of an LED lamp is improved.

Description

technical field [0001] The invention belongs to the technical field of lamp masks, in particular to a conical LED lamp optical mask. Background technique [0002] As the light efficiency and power of light emitting diodes (Light Emitting Diode, LED) continue to increase, the era of semiconductor lighting, the fourth generation of lighting, is coming. LED has many advantages: such as low operating voltage, high luminous efficiency, stable performance, long life, good monochromaticity, and good color rendering. LED has been widely used in liquid crystal backlight, daily lighting, traffic lights, automotive lighting and street lighting and other fields. But LED is not equal to LED lamps. LED itself is a point light source, and high-power LED brightness is too high to produce glare, so LEDs cannot be directly used in lighting fixtures. [0003] In the field of LED lighting, many manufacturers only pursue the electrical effects of LED street lights and ignore the optical effect...
