Title:
LED LIGHTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/040895
Kind Code:
A1
Abstract:
An LED lighting device (1) comprises a housing (10), a light source device (20), an optical lens (30) located above the light source device (20) and distributing light therefrom, a reflector (40) in contact with the optical lens (30), and a surface ring (50) arranged on the reflector (40). The housing (10), the light source device (20), the optical lens (30), the reflector (40), and the surface ring (50) are arranged sequentially. The surface ring (50) is fixed on the housing (10) and defines an accommodation cavity (70). The light source device (20), the optical lens (30), and the reflector (40) are all located in the accommodation cavity (70). The LED lighting device (1) has a light output opening (60). The light source device (20) comprises a light source plate (201) and an LED light source chip (202) located on the light source plate (201). Light from the LED light source chip (202) passes through the optical lens (30), is then reflected by the reflector (40), and is then emitted from the light output opening (60). The LED lighting device (1) does not need a diffusion plate to make light uniform, increases luminous efficiency, and prevents glare, achieving an excellent lighting effect.
