Light emitting diode (LED) illuminating device capable of adjusting color temperature

Abstract

A light emitting diode (LED) illuminating device capable of adjusting color temperature comprises a base (1), an LED light panel (2) arranged on the base, one or more LED light sources (3) arranged on the LED light panel (2), a light-emitting cover (4) which is arranged on the upper portion of the LED light panel (2) and is used for adjusting the color temperature of the light transmitted by the LED light sources (3), a rotary light-emitting cover support (5) and a rotary knob (6), wherein a gear is arranged on the periphery of the light-emitting cover support (5), the light-emitting cover support (5) is used for fixing the light-emitting cover (4), and a gear is arranged at one end of the knob (6). The gear of the light-emitting cover support (5) meshes with the gear of the knob (6), the knob (6) rotates to drive the light-emitting cover support (5) to rotate, the light-emitting cover (4) rotates, and the adjustment of more than two color temperature can be achieved. By the aid of the device, the conversion between the functional lighting and the scene lighting is achieved conveniently under the condition that the light is not disassembled, and psychological and physiological lighting requirements of persons in daily life are met.

Description

technical field [0001] The invention relates to an LED lighting device. In particular, it relates to an LED lighting device capable of adjusting color temperature. Background technique [0002] 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, etc.; the medium color temperature gives people a refreshing, sharp and fashionable feeling, suitable for reading, Dining, etc.; high color temperature gives people a pure, fresh, bright and serious feeling, which is more suitable for the rational side, such a...

AI Technical Summary

Problems solved by technology

[0005] However, there are many defects in the LED light source equipment of the prior art, the most common one is that the color temperature and color of the light cannot be automatically adjusted, and manual replacement is required, which is time-consuming and laborious.

Or although automatic adjustment is basically realized, the adjustment structure is very complicated, the production process is complicated, the cost of materials and processing is high, and it is easy to cause high failure rate of light source equipment and unstable quality
