Problems solved by technology

[0003] Traditional LED lamps are packaged with a single LED chip with a power of 1 watt or 3 watts. Each chip is equipped with a small PC lens. The power is small, and it is difficult to distribute light when using multiple chips together. It is also difficult to handle heat dissipation. The wiring is complicated, Poor reliability cannot meet the needs of high-power lighting

Abstract

The invention relates to a LED lamp head with big power, comprising bottom seat of lamp head, aluminum matrix plate and lens. Groove is set on the upper surface of said bottom seat of lamp head and several concave holes are set on the aluminum matrix plate. LED chips with big power are set in several concave holes. The aluminum matrix plate is fixed in the groove and the lens is fixed above the aluminum matrix plate. Compared with prior technology, the invention is provided with simple structure, small cubage, beautiful figuration, waterproof and dustproof, high integration and high power. The power of single lamp head can achieve 10W-40W. The invention adopts UV glue as heat conduction glue. Not only heat conduction ability is strong but also it is fastness and reliable. It is strong against ultraviolet radiation.

Description

technical field [0001] The invention relates to an LED lamp, in particular to a high-power LED lamp holder. Background technique [0002] Led (Lighting emitting diode) is a light-emitting diode, which is a semiconductor solid-state light-emitting device. It uses a solid semiconductor chip as a light-emitting material. In the semiconductor, the excess energy is released through the recombination of carriers to cause photon emission, and directly emits red, yellow, blue, green, blue, orange, purple, and white light. Led lights are lighting fixtures that use LEDs as light sources. [0003] Traditional LED lamps are all packaged with a single LED chip with a power of 1 watt or 3 watts. Each chip is equipped with a small PC lens. The power is small, and it is difficult to distribute light when using multiple chips together. It is also difficult to handle heat dissipation. The circuit is complicated and Poor reliability cannot meet the needs of high-power lighting. Contents of...
