The invention provides an LED modulator tube adaptive to the installing height. The LED modulator tube comprises a lamp shell, a drive power source and a double-face LED module arranged in the lamp shell. The upper face and the lower face, extending in the length direction of the lamp shell, of the double-face LED module are provided with LED light sources. The lamp shell is further provided withlight sensing elements with the light sensing faces towards the upper portion of the lamp shell. The drive power source and the LED light sources are connected, and the light sensing elements transmitdetected brightness signals above the lamp shell to a controller in the drive power source, and the controller changes the magnitude of the current output to the two LED light sources through the drive power source according to different brightness signals. According to the LED modulator tube, the height between the modulator tube and a ceiling can be automatically detected, the current magnitudeand the light emitting proportion of the LED light sources on the upper face and the lower face are adjusted, the luminous flux needed for key lighting is not wasted, and the optics effect of top lighting is achieved.
Description
technical field [0001] The invention relates to the technical field of lighting, in particular to an LED lamp tube with self-adaptive installation height. Background technique [0002] LED lamps have replaced traditional incandescent lamps and gas discharge lamps and become the main products in the current lighting field. LED light tubes naturally become a substitute product for fluorescent light tubes. In various fluorescent light tube lamps and use environments, LED light tubes can be used as substitute products to achieve more energy-saving purposes. However, due to the characteristics of the directional light source of the lamp bead, the LED light tube can only be designed to emit light from one side, that is, the light-emitting surface of the light tube is downward after the light tube is installed. However, in some special occasions, such as subway stations, such as some warehouse corridors where few people pass by, if this kind of single-sided LED light tube is insta...
