Light control device, design method and lighting system

Abstract

The embodiment of the invention discloses a light control device, a design method and a lighting system. The light control device comprises a reflection cup and a light source fixing structure, one end of the light source fixing structure is fixed at one end of the reflection cup, and the other end of the light source fixing structure extends to the upper part of a reflection cavity of the reflection cup. The side, faces the reflection cavity of the reflection cup, of the light source fixing structure is used for fixing a light source, and the light emitting surface of the light source faces the reflection cavity of the reflection cup. The reflection cavity of the reflection cup comprises a free curved reflection surface used for modulating all light emitted by the light source and formingpreset light spots on the irradiation surface, and the free curved reflection surface is determined according to parameters of the light emitting surface of the light source and output parameters ofthe irradiation surface. According to the technical scheme, distribution of the light emitted by the light source can be controlled, so that the irradiation surface outputs the preset light spots according to illumination requirement.

Description

technical field [0001] Embodiments of the present invention relate to lighting technology, and in particular to a light control device, a design method and a lighting system. Background technique [0002] Since light emitting diodes (Light Emitting Diodes, LEDs) have many advantages such as small size, low power consumption, long life, high brightness, low calorific value, and durability, they are more and more widely used in the lighting field. [0003] In some lighting applications, it is necessary to modulate the light emitted by the LED. For example, in many scenes, the lighting light is required to have relatively good brightness uniformity. figure 1 Shown is a schematic structural view of a lighting device in the prior art, which includes LED1 and reflective cup 2 . Existing lighting devices generally adopt a coaxial design, that is, the LED1 and the reflector 2 have the same optical axis, and the light output direction of the LED1 is the same as the light control dir...

AI Technical Summary

Problems solved by technology

Existing lighting devices generally adopt a coaxial design, that is, the LED1 and the reflector 2 have the same optical axis, and the light output direction of the LED1 is the same as the light control direction of the reflector 2. In this design, a large part of the light emitted by the LED1 It is shot directly and does not hit the reflector 2, so a lot of light is not controlled by the reflector 2, and cannot meet the requirement of outputting any light spot
