A dimming device

Abstract

The invention relates to a dimming device. The dimming device comprises a base (1) and a light transmission cover (4), wherein the base (1) is provided with an LED (Light Emitting Diode) lamp panel (2), and the light transmission cover (4) is arranged above the LED lamp panel (2). According to the dimming device disclosed by the invention, the position of the LED lamp panel (2) can be adjusted through a rotating mechanism, so that LED light sources (3) with different color temperature values in different luminous areas on the LED lamp panel (2) can be sequentially electrified to shine, or signal luminous areas on the LED lamp panel (2) can be rotated to move to positions which correspond to different color temperature areas on the light transmission cover. According to the dimming device, conversion between functional illuminating and scene illuminating can be very conveniently realized by a user under the situation that a lamp does not need to be disassembled, and psychological and physiological illuminating needs of people in production and life can be met.

Description

[0001] The present invention is a divisional application with the original application number 201210590048.3 and the original title of the invention is an LED lighting device with adjustable color temperature, and the original application date is December 30, 2012. technical field [0002] The invention relates to a dimming device. In particular, it relates to an LED lighting device capable of adjusting color temperature. Background technique [0003] With the continuous improvement of living standards, people are no longer satisfied with a single lighting method, and people are gradually pursuing rich and dynamic lighting colors. Light sources with different color temperatures can create different light environment effects and light colors, thus giving people different psychological feelings. Through a lot of comparative research, the low color temperature gives people a warm, comfortable and classic feeling, which is more suitable for the emotional side, such as chatting,...
