A telescopic plant light comprises a plurality of light bars and a drive device. The light bars are arranged side by side. Every adjacent two of the light bars are connected by a linkage telescopic mechanism to move toward each other or to move away from each other. The drive device is electrically connected to each of the light bars. Through the linkage telescopic mechanism connected between every adjacent two of the light bars, the distance between every adjacent two of the light bars is adjustable according to needs. In normal use, the distance between every adjacent two of the light bars can be increased. When not in use, the light bars are moved to be close together, so as to effectively reduce the space occupied by the product. It is convenient for storage, packaging and transportation. The product is very convenient to use.

A wavelength converter according to the present disclosure includes a wavelength conversion layer having a first surface on which excitation light that belongs to a first wavelength band is incident and a second surface different from the first surface and converts the excitation light into fluorescence that belongs to a second wavelength band different from the first wavelength band, and a base so provided as to face the second surface. The base includes a first heat dissipation section so provided as to face a light incident area of the first surface that is an area on which the excitation light is incident and a second heat dissipation section the thermal conductivity of which in a first direction that intersects the first surface is lower than the thermal conductivity of the first heat dissipation section.

A keyboard device and a backlight module of the keyboard device are provided. The keyboard device includes a casing, the backlight module, a keyboard module and an expansion module. The backlight module includes a main body region and an extension region. The main body region and the extension region are connected with each other. A first light beam is outputted from the main body region to plural keys of the keyboard device. A second light beam is outputted from the extension region to the expansion module.

An omnidirectional LED light wire and a packaging method thereof, a light source and a lamp, and in particular, to the technical field of LED lighting. The omnidirectional LED light wire includes one or more than one flip chip and two or more than two conductive components. The one or more than one flip chip is connected through the conductive components to realize an electrical connection relationship, in single, in series, parallel or a combination of series and parallel, of the one or more than one flip chip. In view of technical problems of low efficacy, low temperature resistance and poor heat dissipation of the existing FPC substrate, the disclosure breaks bottlenecks of temperature resistance and dissipation of the FPC substrate.
