Problems solved by technology

For example, 1) The light of each LED bulb is too bright, it will strongly irritate the eyes, do not look directly at it, and the light is not soft
2) The irradiation angle is limited, generally only 120 degrees
3) LED energy-saving lamps only have high brightness in a narrow angle of direct viewing, and the light rapidly weakens after deviating from this angle
[0016] The above method of improving the adhesion between the coating and the substrate by changing the chemical composition has the following disadvantages: sometimes the improvement of the adhesion is at the expense of the reflection ability of the coating to light, that is, although the adhesion is improved, the coating The reflective ability of the layer to light is reduced, and the selection of coating materials is limited, which increases the cost of materials

Abstract

The invention provides a light emitting diode (LED) lamp with a light softening structure. The LED lamp comprises a light transmitting cover and an LED light source, wherein light emitted by the LED light source is emitted out through the light transmitting cover. The LED lamp is characterized in that the light softening structure comprises a light softening coating, and the light softening coating is arranged at the inner side surface and / or the outer side surface of the light transmitting cover and is formed through coating paint. In addition, a plurality of concave points or convex points can also be etched on the base surface of the coated coating. The LED lamp has the advantages that the coating is coated on the light transmitting cover and / or a reflecting cover, and in addition, a great amount of the concave points or convex points are etched on the base surface of the coated coating, so the softening effect is effectively realized on the light emitted by the LED light source, in addition, the adhesive force between the coating and a coated base is enhanced, and the coating is durable.

Description

Technical field [0001] The invention relates to an LED lighting device, in particular to an LED lamp with a soft light structure. Background technique [0002] LED (Light Emitting Diode, Light Emitting Diode), as a new generation of solid cold light source with wide application and rapid development, due to its unparalleled energy saving, long life, small size, fast response, low driving voltage, excellent shock resistance, high efficiency and environmental protection Such technical advantages are widely used in various indications, displays, decorations, backlights, general lighting and urban night scenes, and can replace traditional lighting sources, such as incandescent lamps and fluorescent lamps.
