Lighting fixture

The invention relates to a lighting fixture.

In everyday life, lighting equipment is an indispensable tool. Most of the existing lighting equipment uses a light bulb or a light tube as a light source. Among these lamps or bulbs, fluorescent tubes, incandescent bulbs, and halogen bulbs are commonly used. In recent years, a light-emitting diode (LED) is used as a light source because it consumes a large amount of electric energy during illumination. Lighting equipment has become increasingly popular.

The light-emitting diode has the advantages of long life, low power consumption, small volume and shock resistance, and is not easily broken, and is safe for the user. Conventional LED lighting devices can only provide light of a single color temperature or a single wavelength. For example, if the LED lighting device uses a cool white light emitting diode as the light source, the LED lighting device can only produce cool white light. If the LED lighting device uses a warm white light emitting diode as the light source, the LED lighting device can only produce warm white light. The user cannot change the color temperature or wavelength of the LED lighting device unless the type of the light-emitting diode is replaced.

In addition, when LED lighting equipment is used for plant lighting, Blue light is good for the growth of leaves, while red light is good for flower and fruit growth. Therefore, it is not possible to use a single conventional LED lighting device for different kinds of plants or the same plant at different growth stages. Users need to buy different color temperatures or Multiple sets of LED lighting devices of different wavelengths illuminate the plants, making it difficult to reduce the cost.
