Multi-angle light emitting unit and intelligent lighting device

Abstract

The invention discloses a multi-angle light emitting unit and an intelligent lighting device. The multi-angle light emitting unit comprises a lower substrate, an upper substrate, an optical packagingbody, light emitting units and a driving circuit board. The upper substrate is provided with a plurality of cavities and is formed on the lower substrate, cavity deflection angles are formed between the cavities and the horizontal plane and the vertical plane of the lower substrate correspondingly, and the light emitting units are located in the cavities respectively. When the light emitting unitsare driven by forward light emitting signals, the light emitting units simultaneously project light according to the forward light emitting signals, and when the light emitting units are driven by oblique light emitting signals, the light emitting units alternately project light according to the time sequence corresponding to the oblique light emitting signals, and the light projected by the light emitting units is guided by the corresponding cavities to be deflected to form oblique emergent light. Therefore, the intelligent lighting device composed of the multi-angle light emitting unit is simple in structure, diversified in lighting design and low in cost, saves more energy, and can be widely used in the fields of indoor lighting, outdoor lighting and special lighting.

Description

technical field [0001] The present invention relates to a light emitting unit and its illuminating device, in particular to a multi-angle light emitting unit and an intelligent illuminating device. Background technique [0002] Light-emitting diodes (LEDs) have been widely used in various fields of indoor, outdoor and special lighting, but the basic characteristics of some LEDs, such as directivity, high response speed (no delay in lighting), etc., have not been fully and effectively utilized. [0003] Lighting fixtures are the main carrier of LED light sources. Nowadays, LED light sources and heat dissipation devices are often fixed on them. Generally, the light is emitted perpendicular to the light emitting surface of the LED package, and the specific light intensity, beam angle and light distribution curve are formed by secondary optical design or lamp design to meet different lighting needs. [0004] However, the fixed position of the lamps and lamp holders also restric...

Problems solved by technology

[0020] Lamps with an affine light structure usually set a lens on the light-emitting surface to modify the light-emitting angle. The lens will cause the attenuation of the light-emitting efficiency. The flat-plate structure generally has no lens setting, and the light efficiency is relatively high, but the light will be uneven under close-range irradiation. problem occurs
