Abstract

The invention discloses an LED (Light Emitting Diode) lighting device. The LED lighting device is used for enabling a lighting environment having optimal eye protection performance. The LED lighting device comprises an ambient illuminance sensor, a light emitting body, a heat dissipation device and a controller; the light emitting body comprises a first light source and a second light source; theheat dissipation device has different operating modes and different heat dissipation capabilities; and the controller includes a dimming portion, a storage portion, a judging portion, and an executionportion, wherein the dimming portion is used for adjusting the color temperature of the irradiation light of the LED lighting device, the storage portion stores light adjusting and color adjusting curves for defining the dimming control modes of the dimming portion, the judging portion is used for judging whether the light emission efficiency of the light emitting body is lower than a set value,and the executing section is used for selecting the operating modes of the heat dissipation device. The illuminance and color temperature of the irradiation light of the LED lighting device can be automatically adjusted, so that a lighting environment having optimal eye protection performance can be realized; and heat dissipation performance can be automatically adjusted according to illuminationparameters, so that the service life of the LED lighting device can be prolonged.

Description

technical field [0001] The invention belongs to the field of LEDs, in particular to an LED lighting device. Background technique [0002] LEDs that provide high-intensity lighting with low power are increasingly used in vehicles, and by individually controlling the lighting of multiple LEDs, it is possible to adjust the light distribution and illuminance of the irradiated light. There are various lighting devices in the prior art that can control the output ratio of the light source and can adjust the illuminance and color temperature of the irradiated light. Although this LED lighting device can automatically or intelligently adjust the irradiation light, its heat dissipation device cannot be matched with automation or intelligence. Contents of the invention [0003] In order to solve the above problems, the present invention provides an LED lighting device for forming a lighting environment with optimal eye protection, which is characterized in that it includes an ambie...
