Patent number: 9589440Abstract: A lamp tube and a lamp fixture with sensing capability are disclosed. The lamp tube with sensing capability includes a lamp tube body, and the lamp tube body includes a power converting unit, an LED strip and a sensing unit. The power converting unit is for receiving AC power and outputting DC power for driving the LED strip and the sensing unit. The sensing unit will timely output a fire alarm signal to notify the firemen and the people nearby when a fire occurs. The shape of the lamp tube with sensing capability is the same as a normal lamp tube, so both of them can be installed in the same lamp fixture. One normal lamp tube is replaced by the lamp tube with sensing capability to include a fire sensing function. The safety is enhanced and the installation is convenient.Type: GrantFiled: June 29, 2015Date of Patent: March 7, 2017Assignee: LUXUL TECHNOLOGY INCORPORATIONInventors: Cheng-Hung Pan, Eric Wen-Chien Chen, Perng-Fei Yuh, Yung-Ta Hung, Cheng-Hsien Chen
