Embodiment Construction

[0017] The preferred embodiments of the present invention are given below in conjunction with the accompanying drawings to describe the technical solution of the present invention in detail.

[0018] refer to figure 1 , The LED downlight of the present invention includes a light source 7, wherein the light source 7 includes a plurality of white LEDs and a plurality of colored LEDs. Colored LEDs here refer to those white LEDs that emit neither standard white light nor white LEDs that emit warm white or cool white light, such as common red LEDs, green LEDs, and blue LEDs.

[0019] Specifically, the plurality of colored LEDs include LEDs of more than one colored light. In the present invention, the plurality of colored light LEDs in the light source can all belong to the same color light LED, for example, red light LEDs are selected, or they can belong to two or more color light LEDs, for example, some of the color light LEDs The light LED is made of red light LED, while the re...

Abstract

The invention discloses an LED downlight, including a light source. The light source comprises at least one white light LED and at least one colorful light LED. At least one colorful light LED besides at least one white light LED is used in the light source of the LED downlight of the invention. By being mixed, the light emitted by various colorful light LEDs can produce illumination effects which are soft, non-glare and high in color rendering. On top of that, through independent control for luminous flux of the various colorful light LEDs, the flexible adjustment for light emitting color temperature, color, brightness and color rendering of the LED downlight can be realized, thereby creating a better illumination environment.

Description

technical field [0001] The invention relates to a lamp, in particular to an LED downlight. Background technique [0002] At present, with the development of the economy, indoor lighting, landscape lighting and architectural lighting have received more and more attention and attention. From the beginning, lighting only focused on brightness, and now it pursues beauty while pursuing brightness. From the initial general Lighting sources are now integrated into high-tech, and lighting sources and lighting methods are becoming more and more diversified, making our cities more and more beautiful at night. For different environments and needs, white light with different color temperatures is required. For example, warm white light is suitable for some occasions, and cool white light is suitable for other occasions. However, a single white LED cannot continuously adjust the color temperature and lacks changes. [0003] In addition, the color rendering ability of the light source to...
