Intelligent LED bulb with dustproof function

Abstract

The invention discloses an intelligent LED light bulb with dustproof function, which comprises a lamp base (1), a lamp body (2) and a mask (3), and the lamp body (2) is provided with an LED drive circuit from bottom to top, Dust-proof structure, ring connection structure (4), adjustment rod (5) and LED luminous body, the dust-proof structure is equipped with an electrostatic dust-proof net (6), and the electrostatic dust-proof net (6) is electrically connected to Negative high-voltage pulse generating circuit, the negative high-voltage pulse generating circuit is connected to the LED drive circuit, the annular structure is arranged above the electrostatic dust-proof net, and the inner of the annular connection structure (4) is provided with an infrared sensor (7), positioning Device (8), drive device (9) and circuit board (10). The LED lamp has a dust-proof function, and the lighting effect is good. At the same time, the light source can be adjusted according to the user's position, thereby achieving the purpose of saving energy.

Description

technical field [0001] The invention relates to the lighting field, in particular to an intelligent LED light bulb with dustproof function. Background technique [0002] The traditional tungsten filament light bulb uses the principle of thermoluminescence, which has low energy conversion rate, high heat generation, short service life and unsatisfactory lighting effect. The fluorescent light bulbs that appeared later were not environmentally friendly due to the use of a large amount of phosphor powder. At present, LED lights can directly convert electricity into light, overcome many shortcomings of tungsten bulbs, and are widely replaced. However, in LED light bulbs, the light emitting direction of the LED is generally forward. Due to the limitation of the light emitting angle of the LED itself, the existing LED light bulbs have a taper angle, which cannot be different from the traditional incandescent light bulbs and fluorescent light bulbs. Directional light, at the same ...

However, in LED light bulbs, the light emitting direction of the LED is generally forward. Due to the limitation of the light emitting angle of the LED itself, the existing LED light bulbs have a taper angle, which cannot be different from the traditional incandescent light bulbs and fluorescent light bulbs. Directional light, at the same time in a dark room, because the light source of the existing LED bulb is single and fixed, when a person moves to an area outside the fixed light source, other lights need to be turned on for lighting, which often causes a waste of electricity; If the lamp is used for a long time, it is easy to accumulate dust inside the mask, which will affect the lighting effect of the LED lamp
