Abstract

The invention provides a high-luminous-efficiency LED lamp, which includes a lamp body, wherein an LED light source installation base is arranged in the lamp body, a plurality of LEDs are evenly distributed on the surface of the LED light source installation base, and a reflective light is provided around the LED light source installation base. The reflector is a flexible reflective material board. The angle between the reflector and the LED light source installation base is adjusted by the angle adjustment mechanism. The LED light source installation base, reflector and LED lamp are equipped with a lampshade, and the lampshade is filled with heat-conducting gas. , the lamp body is also equipped with a controller, the controller controls the angle adjustment mechanism to adjust the inclination, wherein the heat transfer gas is a mixture of one or more mixed inert gases in helium, neon, argon and oxygen, and in addition The components of the LED light source installation base include (mass fraction): 25%-43% of dimethyldichlorosilane, and 54%-75% of high thermal conductivity powder. Surfactant 1%‑2%. The LED lamp with high luminous efficiency provided by the present invention improves the concentration of light, can dynamically adjust the beam angle, reduces light attenuation, and improves luminous efficiency.

Description

technical field [0001] The invention relates to the technical field of LED lighting, in particular to a high-luminous-efficiency LED lamp with automatic brightness adjustment. Background technique [0002] Because LEDs have the characteristics of long service life, low energy consumption, and significant energy saving, LEDs have been widely used as light sources in daily life, such as cup lights, spotlights, car lights, LED bulbs and other LED lighting fixtures. [0003] At present, LED light bulbs generally include a lamp cap, a lampshade installed on the top of the lamp cap, and a power supply located in the lamp cap. An LED light-emitting column is arranged in the lampshade. The LED light-emitting column is electrically connected to the power supply in the lamp cap, and the LED light-emitting column is fixed on the heat dissipation substrate. When the LED light-emitting column is energized to emit light, the light emitted by it can be irradiated through the lampshade to a...
