Problems solved by technology

[0003] At present, in the structure of LED lamps, a lens is generally used in front of the LED lamp to maximize the luminous efficiency of the LED; The light makes the lamps have the same illuminance in all directions. When LED lamps are applied to building landscape lighting, the lighting light distribution cannot be configured according to the landscape light distribution requirements, so that the lighting of the building landscape cannot achieve satisfactory visual effects, thereby reducing Improve the utilization of light and reduce the brightness of the building landscape

Abstract

The invention discloses an LED asymmetric light-distribution lamp fitting which comprises an LED lamp and an optical lens, and the optical lens is arranged above the LED lamp and is formed by combining a Fresnel lens and a cylindrical lens. In the invention, the optical lens formed by combining the Fresnel lens and the cylindrical lens is arranged above the LED lamp, the light emitted by the LED lamp is gathered by passing through the Fresnel lens, the optical lens plays a role of gathering light and enhancing the light utilization efficiency, the light generates offset after passing through the cylindrical lens, then asymmetric light-distribution is generated, and the illuminance and the intensity of the light are further enhanced. The invention can distribute light according to lighting needs of building landscape when being used, can ensure the building landscape to obtain good visual effect, and can enhance the light utilization efficiency.

Description

technical field [0001] The invention relates to a lamp, in particular to an LED asymmetrical light distribution lamp. Background technique [0002] LED (light emitting diode, light-emitting diode) lamps adopt electric field luminescence, which changes the principle of tungsten filament luminescence of incandescent lamps and three-based toner luminescence of energy-saving lamps. Because LED lamps have uniform and high purity of light, small luminous heat, concentrated beams, and low power consumption It has been more and more widely used due to its superior properties such as low weight and long life. [0003] At present, in the structure of LED lamps, a lens is generally used in front of the LED lamp to maximize the luminous efficiency of the LED; The light makes the lamps have the same illuminance in all directions. When LED lamps are applied to building landscape lighting, the lighting light distribution cannot be configured according to the landscape light distribution r...
