Abstract: Provided is a lamp assembly including a lamp main body. The lamp assembly includes at least one light engine, and at least one first connector for electrically connecting the at least one light engine to a power supply and mechanically fixing the last light engine to the lamp main body. The at least one first connector is configured to separably mount the at least one light engine to the lamp main body. In addition, a method for assembling a lamp is also provided.

Abstract: A lighting device with changeable beam angle and fixed center beam candle power. The device may include a light source, an electronic driver for driving the light source to emit light, a beam shaping element for shaping a beam of light emitted by the light source, a beam angle adjustment mechanism configured to change a positional relationship between the light source and the beam shaping element, and a sensor configured to provide a signal indicative of a setting of the beam angle adjustment mechanism. The electronic driver is configured to adjust the luminous flux emitted by the light source depending on the signal provided by the sensor. Such a lighting device may keep the center beam candle power of the emitted light constant when the beam angle is changed.

Abstract: The present invention provides a method, which is used with trace amount, can initiate an active endogenous response of plants, and can obtain expected effects such as growth acceleration and yield increase of the plants. The present invention further provides preparation of a signal carrier material for implementing the method. In the method, by utilizing genetic information stored in the plants, the plants can adapt to an environment through a signal which makes the plants mistakenly perceive, thereby achieving an expected objective. The method is suitable for planting of crops in regions with poor natural conditions or severe climate changes.
