Abstract
The utility model discloses a light emitting diode (LED) lamp with an anti-dazzle high transmittance glass coating. The LED lamp with the anti-dazzle high transmittance glass coating comprises a coating material layer. The coating material layer is coated on the glass inner surface of the LED lamp. The thickness of the coating material layer is from 1micrometer to 50 micrometers. According to the LED lamp, the anti-dazzle high transmittance glass coating can be effectively and evenly attached to the glass surface, diffuse reflection effect of a glass lamp cover is remarkably strengthened, range of lighting of the lamp is enlarged, characters of glass materials such as heat conduction, low cost and high stability are fully utilized, dazzling phenomenon of the lamp is effectively improved, and meanwhile light quantity of the lamp is remarkably improved, and the lamp is suitable for illumination lamps such as LED bulb lamps, ceiling lamps and spot lamps.
Description
Technical field
The utility model relates to a kind of LED light fixture.
Background technology
Light emitting diode (LED) has the advantages such as the long and environmental protection of luminous efficiency height, power saving, life-span, be described as the 4th generation light source, its application is more and more extensive.When LED is applied to normal lighting, in order to reach illumination requirement, generally a plurality of power-type LED spot light dense arrangement are used in a light fixture.During human eye direct-view light source, can see thickly dotted luminous point, feel disability glare.The dazzle meeting makes people's eye-blurred, watches attentively for a long time and can cause eye fatigue, and eyes are caused certain damage.Because the LED illuminating lamp ubiquity of using at present glare problem to a certain degree, if this problem is not well solved, will affect the lighting quality of LED light fixture.Usually in order to prevent dazzle, improve irreflexive effect, what the LED lampshade was selected is ground glass, white or vaporific plastics, but both transmitances are all lower, loss to luminous energy is larger, the heat-conducting effect of plastic material is bad in addition, and the heat radiation of led light source is had certain impact, is unfavorable for that LED works long-term and stably.
Summary of the invention
The purpose of this utility model is to provide a kind of diffuse effect of reinforcing glass lampshade, enlarges the range of exposures of light fixture, effectively improves the LED light fixture with anti-dazzle high permeability glass coating of light fixture.
Technical solution of the present utility model is:
A kind of LED light fixture with anti-dazzle high permeability glass coating is characterized in that: comprise the coating material layer, the coating material layer is coated in LED fitting glass inner surface, and the thickness of coating material layer is 1-50 μ m.
The thickness of coating material layer is 25-35 μ m.
The utility model anti-dazzle high permeability glass coating can be adsorbed on glass surface effectively uniformly, has strengthened significantly the diffuse effect of glass lamp shade, enlarges the range of exposures of light fixture.Take full advantage of the characteristics of glass material heat conduction, low cost and high stability.Effectively improve the glare phenomenon of light fixture, the luminous flux of light fixture is obviously improved, be applicable to the lightings such as LED bulb lamp, lamp affixed to the ceiling and shot-light.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a kind of LED bulb lamp schematic diagram.
Fig. 2 is a kind of LED lamp affixed to the ceiling schematic diagram.
Fig. 3 is a kind of LED shot-light generalized section.
Among the figure: 1. anti-dazzle high permeability glass coating; 2. LED bulb lamp glass bulb; 3. LED lamp affixed to the ceiling glass lamp shade; 4. LED shot-light glass lamp shade.
The specific embodiment
A kind of LED light fixture with anti-dazzle high permeability glass coating comprises coating material layer (being anti-dazzle high permeability glass coating) 1, and the coating material layer is coated in LED bulb lamp glass bulb 2 interior surfaces of glass, and the thickness of coating material layer is 1-50 μ m; The thickness of preferred coatings material layer is 25-35 μ m.
