Abstract

The invention relates to an LED (light-emitting diode) lamp, and particularly discloses an LED filament lamp. A high-transmittance LED filament lamp comprises a lamp base and a bulb, wherein the bulb and the lamp base form a sealed cavity; an upper bracket, multiple LED filaments, a lower bracket and wires are arranged in the bulb from top to bottom; the upper parts of the LED filaments are connected with the upper bracket, and the lower parts of the LED filaments are connected with the lower bracket; the wires are connected with the upper and lower brackets, and are used for supplying power to the LED filaments; a first layer of composite film and a second film layer of composite film are arranged in the bulb from outside to inside; the first layer of composite film is prepared from magnesium fluoride and alumina, and the second layer of composite film is prepared from potassium silicate and silicon dioxide. According to the LED filament lamp, light of different wavebands is absorbed to achieve a multilayer film antireflection effect by virtue of different substances and an refractive index of a special coating structure of different substances; the transmittance of a glass bulb should subjected to double-layer composite coating treatment can reach 99.95 percent or more.

Description

technical field [0001] The invention relates to an LED lamp, in particular to an LED filament lamp. [0002] The invention relates to an LED lamp processing technology, in particular to a high light transmittance LED processing technology. Background technique [0003] LEDs have higher luminous efficiency than traditional tungsten filament lamps, but LEDs are directional and have a small luminous angle. They do not have the full-angle luminous effect of traditional tungsten filament lamps. Vertical arrangement of multiple LED filament lamps can expand the luminous angle, but there are the following disadvantages: [0004] 1. The light emitted by the LED filament is reflected by the bulb and then absorbed, converted into heat, and the light output efficiency is low; [0005] 2. The LED filament is suspended in the bulb, which is not conducive to the heat dissipation of the LED and seriously affects the light output. Contents of the invention [0006] In order to solve the...
