    • The present invention discloses a link adaptation method, a base station and a terminal in a LTE system, wherein the method comprises: a terminal respectively calculating differences between a measured reference signal received power (RSRP) of a home service cell and the RSRPs of multiple adjacent cells; the terminal reporting the maximum difference in the differences to a base station; and the base station determining a modulation and coding scheme (MCS) for the terminal according to the maximum difference. The present invention does not introduce new overhead of the system, simplifies the flow of the AMC, and therefore improves the frequency spectrum efficiency of the system.

    • An LED lamp includes an optical part, a heat dissipation member and an electric part. The optical part includes a hollow light penetrable tube and an LED module received in the tube. The heat dissipation member is received in the tube to mount the LED module thereon. The electric part include a circuit board and a rechargeable battery arranged in the tube, and two end covers arranged at two opposite ends of the tube. The LED module is provided with at least one first LED and at least one second LED. The at least one first LED and the at least one second LED cooperatively function as a main light source to provide normal illumination when an external AC power source is supplied normally. The at least one second LED independently function as an auxiliary light source to provide emergency illumination when the external AC power source is interrupted.
    • LED灯包括光学部件,散热部件和电气部件。 光学部件包括容纳在管中的中空透光管和LED模块。 散热构件被容纳在管中以将LED模块安装在其上。 电气部件包括布置在管中的电路板和可再充电电池,并且布置在管的两个相对端的两个端盖。 LED模块设置有至少一个第一LED和至少一个第二LED。 当正常地提供外部AC电源时,所述至少一个第一LED和所述至少一个第二LED协同地用作主光源以提供正常照明。 至少一个第二LED独立地用作辅助光源,以在外部AC电源中断时提供紧急照明。
