Title:
SMART DIMMING RGB LED SPOTLIGHT HAVING HIGH OPTICAL QUALITY AND IMPLEMENTATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/189684
Kind Code:
A1
Abstract:
A smart dimming RGB LED spotlight having high optical quality, comprising a housing (2); a lamp cap (1) is connected to the bottom end of the housing (2), a drive panel (3) is provided inside the housing (2), a light source panel (5) is provided above the drive panel (3), the drive panel (3) is electrically connected to the lamp cap (1) and the light source panel (5), respectively, a lamp cover (6) is connected above the housing (2), dense regular color temperature beads (52) and several RGB color-changing beads (51) are respectively provided on the light source panel (5), and the lamp cover (6) corresponding to the RGB color-changing beads (51) is connected above the light source panel (5). Further disclosed is an implementation method of the smart dimming RGB LED spotlight having high optical quality, wherein light emitted by the RGB color-changing beads (51) is diffused by the lamp cover (6), such that the light intensity is reduced, and the light-emitting area increases and becomes uniform. The lamp cover (6) does not block light emission from the regular color temperature beads (52), and thus the the irradiated light spot has uniform colors, and the color purity is high and the illuminance is balanced during the multi-color changing process, which can achieve the GB illuminance grade AA effect.
