Abstract

The invention discloses a high-power LED light source with the light beam adjustable, including an LED chip, a packaging base plate, a case, a transparent curved sheet, transparent liquid, a radiator and a steering device, wherein the case and the steering device are arranged on the radiator; the packaging base plate is arranged on the steering device, and LED chips are arranged on the packaging base plate; the top of the case is arranged with the transparent curved sheet, and the space enclosed by the case, the transparent curved sheet and the radiator is filled with the transparent liquid to form the liquid lens. The light generated by the LED chip is emitted through the liquid lens, and the steering device can rotate the packaging base plate and the LED chip, to make the direction and the width of the emergent light beam adjustable; the heat is radiated to the case and the radiator through the transparent liquid, which realizes the problems of adjustable LED optical source output beam and the heat emission.

Description

technical field [0001] The invention relates to an illumination light source, in particular to a high-power LED light source with adjustable light beams. Background technique [0002] LED light source is a new generation of green lighting source. Its power consumption is only one tenth of that of ordinary incandescent lamps, but its life is more than ten times longer. In addition, LED light sources also have the advantages of small size, durability, and rich colors. At present, it has begun to be widely used in applications such as home and public lighting and automobiles. In some application fields, it is necessary to change the output beam of the lighting system to adapt to different usage environments and purposes. For example, the headlights of automobiles need low beams and high beams, and even light deflection as the vehicle turns to improve nighttime driving safety. safety. [0003] Due to the very small die area of ​​the current LED light source, the light emitted...
