Title:
INDOOR LED LAMP WITH ADJUSTABLE ILLUMINATION ANGLE AND INTENSITY
Document Type and Number:
WIPO Patent Application WO/2015/035808
Kind Code:
A1
Abstract:
An indoor LED lamp with adjustable illumination angle and intensity comprises an LED power supply, an LED substrate (7) and LED chips (6) installed on the LED substrate (7), wherein the LED power supply is electrically connected to the LED chips (6); the LED substrate (7) is a hollow cylinder in shape; the LED chips (6) are uniformly distributed on an outer surface of the LED substrate (7); LED chips (6) arranged axially are in a chip group, and a separation plate (3) extending radially outwards is arranged between two adjacent chip groups; and an end of the separation plate (3) is connected to a refractive plate (2). Light emitted by the LED chips (6) of the LED lamp is refracted by the refraction plate (2), with the majority of the light reaching an illuminated area, and a small portion thereof being refracted or transmitted through to the surroundings, so that there is faint light throughout the entire space, not only maintaining a high efficiency of the illuminant system but also effectively reducing glare, thereby improving visual effects and achieving environment protection and energy saving of a light source for domestic illumination.
