Description

An LED imitation filament light bulb

technical field

The utility model belongs to the technical field of LED lamps and relates to an LED imitation filament bulb.

Background technique

Due to the low luminous efficiency, incandescent lamps are gradually being replaced by energy-saving light sources, especially by LEDs. However, in some lamps that are mainly used for decoration, people sometimes want to present some retro styles, so a large number of incandescent lamps are still used. .

In order to combine retro and energy-saving features, some LED bulbs imitating incandescent lamps have appeared. The light body uses laser ablation to ablate many small bubbles in the shape of filaments. The LED is installed in the lamp holder and shines on the transparent plastic plate. Due to the diffuse emission of light on the bubbles, it presents an effect similar to an incandescent bulb. However, the simulation effect of these LED bulbs imitating incandescent lamps is relatively poor.

There is also a Chinese utility model patent application (application number: 201520106314.X) which discloses a new type of energy-saving decorative lamp, which is composed of a light bulb and a lamp cap. The LED lamp body is electrically connected to the PCB board, and the lamp post is fixed on the PCB board under the LED lamp body. There are lines engraved on the lamp post, but the lamp post of the decorative lamp adopts two transparent boards with a poor structure, and the light enters the transparent board. The back of the board causes the two transparent boards to have a luminous effect, and the entire luminous body is relatively large, resulting in a poor effect of the filament produced by the lines on the two transparent boards.
