Problems solved by technology

[0009] Since the distribution of LEDs has a certain angle, the attached circuit board or radiator must form a certain angle with the base, and a special mold needs to be made to match it. However, the cost of mold production is high and the processing is difficult. Afterwards, the angle cannot be adjusted, and a set of molds generally only corresponds to one lighting form or application, that is, the angular distribution of light intensity of LED lamps cannot be changed after leaving the factory, which reduces the scope of application of the lamps.

Abstract

The invention relates to an LED lamp with controllable illumination direction and light distribution. Special illumination patterns are projected by controlling the illumination direction and light distribution of one or more light source modules to meet the requirements of special illumination condition and patterns. The invention can be used for illumination occasions such as building scene decoration illumination, stage light illumination and indoor decoration illumination. Single light source module comprises a replaceable lens for controlling the size of LED divergence angle, a rotation driving unit for controlling the space angle distribution and light intensity variation of LED; and a signal controller for receiving illumination distributing information of users, sending relevant commands to the rotation driving unit, and controlling the rotation angel and the illumination intensity of the rotation driving unit.

Description

technical field [0001] The invention relates to a lighting fixture, in particular to an LED lighting fixture with controllable irradiation direction and lighting style, which is mainly suitable for lighting and decoration of building appearance, stage and indoor lighting. Background technique [0002] In recent years, with the development of semiconductor technology and the successful development of high-power LEDs, LEDs have been widely used as semiconductor light sources in signal display, backlighting, and landscape lighting. With the continuous improvement of the light efficiency of high-power LEDs, LED light sources have gradually entered the field of general lighting. Semiconductor lighting is recognized as the third-generation light source after incandescent lamps and fluorescent lamps due to its energy saving, environmental protection, and long life. [0003] Today's LED lamps generally take the following forms: [0004] One is that the light source is composed of ...
