Abstract
The invention relates to a light-emitting diode (LED) lamp with a double-layer lamp cover. The LED lamp comprises a lamp holder, a lamp base, an LED chip arranged on the lamp base, an outer lamp cover (1) and an inner lamp cover (3). The LED chip and the inner lamp cover (3) are arranged inside the outer lamp cover in a covered mode. The LED lamp is characterized in that at least one of the inner lamp cover (3) and the outer lamp cover (1) is a fluorescence lamp cover which is formed by mixed materials of light-transmitting resin and yellow fluorescence powder in a solidifying mode.
Description
Technical field
The present invention relates to a kind of LED light fixture, especially relate to a kind of LED lampshade with double-layer lampshade.
Background technology
Along with the development of society, the lighting energy consumption problem in daily life becomes increasingly conspicuous, and therefore, the LED light fixture with remarkable power savings advantages more and more is subjected to people's favor.Because the light emitting source of LED light fixture is the LED luminescence chip, if LED chip is arranged on lamp socket, can cause LED light fixture irradiating angle too low, for head it off, the practices well of prior art is to distribute to surrounding in the middle of the light that utilizes light-guiding pillar that the LED light source on lamp socket is distributed is directed to bulb, polygon prism perhaps is set in bulb, the LED luminescence chip is dispersed on several sides of prism, thereby realize larger luminous angle of coverage.
In addition, because the LED luminescence chip belongs to spot light and brightness is high, use the illumination custom of ordinary lamp and lantern in order to adapt to people's many decades, usually use the frosted lampshade on the LED light fixture, make the LED light fixture luminous trend towards soft, but this frosted lampshade has intercepted partial illumination light too much, makes the luminous efficiency of LED light fixture greatly reduce.
The patent No. is that 201120372342.8 Chinese patent discloses a kind of LED light fixture with double-layer lampshade, lampshade cover cap LED chip in using, and described internal layer lampshade is the lens that are mixed with fluorescent material.By the light activated phosphor that LED chip gives out, experience thereby obtain the user identical with ordinary lamp and lantern.But all fluorescent powder lens lampshades all adopt the injection mo(u)lding of solids mixing fluorescent material at present, maybe will plate fluorescent powder jet printing makes in Transparent lamp shade, technological requirement is high, especially for light-emitting lamp shade, if fluorescent material can not evenly distribute, can have a strong impact on illuminating effect in injection moulding and spraying plating process.
Summary of the invention
Purpose of the present invention: be intended to propose a kind of LED light fixture of high quality and low cost double-layer lampshade, it is simple in structure, and production cost is low, has larger lighting angle and meets people's use habit for a long time.
This LED light fixture with double-layer lampshade comprises lamp holder, lamp socket, is arranged at LED chip, outer lampshade and interior lampshade on lamp socket, described LED chip and the equal quilt cover of interior lampshade are placed in outer lampshade, it is characterized in that: in described interior lampshade and outer lampshade, at least one cover body is by light-transmissive resin and yellow fluorescent powder compound curing molding fluorescent lamp shade.
Described interior lampshade or outer lampshade are made base-material with epoxy resin or the silica gel of liquid condition, with yellow fluorescent powder as compound, and press the proportioning formation of adding 0.3-10 weight portion yellow fluorescent powder in the base-material of every 100 weight portions and make the fluorescent lamp shade liquid charging stock, subsequently by injection moulding process or directly forming the fluorescent lamp shade of required moulding after natural moulding in liquid charging stock injection die cavity, cure and demold.
The particle diameter of fluorescent powder grain is at 5-25um.
Described silica gel is two component silica gel.
Described epoxy resin is bi-component epoxide-resin.
Described lamp socket upper end is provided with LED support, and described LED chip is arranged on LED support.
Described interior lampshade cover cap is on LED support, and described outer lampshade cover cap is on lamp socket.
The present invention is by adopting by light-transmissive resin and yellow fluorescent powder compound curing molding lampshade; Perhaps in the outside of interior lampshade, or the phosphor powder layer of the inner face of outer lampshade coating, make at least one in both become the alternating light cover, can reduce expensive that the fluorescent material Shooting Technique causes.In addition, adopt phosphor powder layer to be sprayed on the outer surface of interior lampshade, make spraying coating process simpler, quality is more reliable.Particularly for narrow space in the interior lampshade of some abnormity or outer lampshade, particularly in the acute angle junction, be difficult to guarantee the uniform fold of phosphor powder layer, cause illumination effect not good, and adopt the way of external spray, be easy to solve problems.
