LED illumination light distribution mode

Abstract

The invention discloses an LED illumination light distribution mode. The LED illumination light distribution mode is based on the characteristics of the requirements of the dark environment operationand the human binocular vision for the illumination, and is used for overcoming the defects that according to the light distribution mode of an existing portable LED illumination product, the irradiation angle is fixed, the light spot shape is fixed, and the visual field illumination coverage rate is low. The irradiation angle and the irradiation direction of lamplight can be changed according tothe site situations, the illumination mode and the visual field illumination range can be adjusted, and the operation and action requirements can be met. The LED illumination light distribution mode comprises an LED unit set, a light distribution regulation and control system and a power source. The LED unit set includes two or more LED units. The light distribution regulation and control system generates a bright zone by changing the irradiation angles and the irradiation directions of the LED units and adjusting the overall lamplight projection angle of the LED unit set, wherein the bright zone is changeable in overall light spot shape and adjustable in area and comprises a wide-angle view illumination section. The LED illumination light distribution mode is mainly used for providing anLED illumination vector light distribution method with the higher adaptability, flexibility and humanization for research and development of a novel LED illumination product which better accords withthe physiological characteristics of the human binocular vision and meets the diversified illumination requirements.

Description

Technical field [0001] The invention relates to a vector light distribution mode that can expand the LED lighting characteristics and illumination range and enhance the applicability and flexibility of LED lighting products by adjusting and changing the light distribution mode of LED lighting according to the needs of on-site lighting and the physiological function characteristics of human binocular vision. . Background technique [0002] People often use LED devices such as headlights for lighting when working in dark environments. At present, the existing portable LED lighting devices at home and abroad mainly have five modes in terms of light distribution technology characteristics: ①A single light source and a single reflector cup structure are used, and the light distribution is performed by adjusting the relative position of the light source point and the focus of the reflector cup , high light reflectivity. ② Using multi-light source and multi-reflector cup structur...
