Problems solved by technology

The floodlight can only adjust the irradiation angle up and down on the base, and cannot change the light intensity in a specific area
In addition, left and right adjustments cannot be realized, which greatly limits the light projection direction of the lamp body, resulting in the LED floodlight not being able to illuminate any place that needs to be illuminated, which greatly reduces the scope of application of the LED floodlight

Abstract

The invention discloses an LED (Light-Emitting Diode) projection lamp with an adjustable irradiating angle. The LED projection lamp mainly comprises an LED module, an installation bracket and an LED module light projecting angle adjusting device, wherein the LED module comprises a transparent lampshade, a plurality of LED particles and a radiator; the LED module light projecting angle adjusting device comprises an inner frame, a middle frame and an outer frame; the LED module is arranged in the inner frame; the inner frame is positioned in the middle frame; the middle frame is positioned in the outer frame; the outer frame is connected with the installation bracket; and the angles between the inner frame and the middle frame as well as between the middle frame and the outer frame can be adjusted relatively. Due to the adoption of the LED projection lamp with an adjustable irradiating angle which has the advantages of simple structure, comprehensively adjustable angle and accurate positioning, the requirement of accuracy positioning on the LED projection lamp in different application environments is met, the position arrangement flexibility of the LED projection lamp is enhanced, and the application occasion of the LED projection lamp is expanded.

Description

technical field [0001] The invention relates to an LED lighting fixture, in particular to an LED floodlight with adjustable irradiation angle. Background technique [0002] With the improvement of the public's requirements for lighting quality, floodlights are widely used in outdoor floodlighting, architectural decoration lighting, industrial site lighting, sports centers and outdoor stadiums, ports, docks, etc. LED has a specific luminous angle, which cannot be as large and uniform as traditional light sources. If multiple LEDs are mounted on a flat circuit board, the light emitted by the multiple LEDs arranged in a plane is basically emitted in a direction perpendicular to the circuit board. , resulting in a smaller spot in front of it, that is to say, the irradiation angle of the LED floodlight is smaller. In order to increase the irradiation angle of the LED floodlight and improve the light projection effect of the LED floodlight, Chinese patent CN201795380U discloses a...
