Abstract

The invention relates to an LED illumination device which comprises one or more LED light source modules and a driving module, wherein each LED light source module comprises a substrate and a plurality of LED light sources; a circuit is arranged on each substrate, and the plurality of LED light sources are arranged on the substrates; the electrodes of the plurality of LED light sources are electrically connected with the circuits on the substrates; the driving module comprises a driving source and a rotating shaft which are fixedly connected; the rotating shaft is fixed on the side surfaces of the substrates; and the substrates are driven to rotate by the rotation of the driving source to regulate the illumination angle of the LED sources. In the LED illumination device, the driving source is used for regulating the illumination angles of the LED light source modules so as to change light distribution curves of the LED light source modules and achieve the purpose of regulating the light field distribution under different external environments.

Description

technical field [0001] The invention relates to an illuminating device, in particular to an illuminating device capable of changing light field distribution and light distribution curve. Background technique [0002] A light emitting diode (LED, Light Emitting Diode) is a semiconductor element that can convert electric current into light in a specific wavelength range. Light-emitting diodes have the advantages of high brightness, low operating voltage, low power consumption, easy matching with integrated circuits, simple driving, and long life, so they can be widely used as light sources in the field of lighting. For details, see Joseph Bielecki et al. in literature 2007 IEEE, Thermal Considerations for LED Components in an Automotive Lamp in the 23rd IEEE SEMI-THERM Symposium. [0003] Since LED is similar to a point light source, when it is made into a device, it usually needs an optical design to change its light field distribution. The light distribution curve of a com...
