Abstract
The utility model discloses an LED reflection lampshade, comprising a lampshade body, wherein the lampshade body is provided with an inner cavity; the peripheral wall of the inner cavity is a reflecting surface; the inner cavity is horn-shaped gradually dispersing from an axial inner end close to an LED light source to an axial outer end far away from the LED light source; and the peripheral wall of the inner cavity is circumferentially divided into a plurality of reflecting subareas, and the axial section of each reflecting subarea is provided with a curvature protruding facing towards the radial center of the inner cavity. The LED reflection lampshade corrects the optical curvature of the reflecting surfaces of the inner cavity in the lampshade, arranges a nano mirror surface film-coating layer in the reflecting surfaces, reduces the heat collected in the lampshade due to the reflection lampshade, reflects the light rays and heat to a light ray irradiation area, and prolongs the service life of an LED illuminating device while improving the practical light efficiency of the LED illuminating device.
Description
Technical field
The utility model relates to a kind of LED lampshade.
Background technology
LED (light emitting diode) has that energy consumption is low, caloric value is lower and the advantage of long service life, and in today of global energy shortage, the above-mentioned environmental protection characteristics of LED have wide application space.The LED lighting device also can be covered with lampshade outside led light source except led light source, this lampshade can be provided with reflection shield towards a side of led light source, light is assembled, to improve the actual light efficiency of LED lighting device.The inner chamber of this reflection shield is generally cylindrical or cone platform shape, it also can be with heat accumulation in lampshade when light is assembled, make LED lighting device increase in temperature, and then can cause problems such as circuit control system instability, lamp life reduction.
Summary of the invention
The utility model purpose provides a kind of LED lampshade, it has reduced the heat of assembling because of reflection shield in lampshade, light and heat are more reflexed to the light irradiated region, when improving LED brightness, avoid electronic installation in the lampshade to be in high temperature for a long time and cause the problem that the life-span shortens.
The technical solution of the utility model is: a kind of LED lampshade, comprise the lampshade body, described lampshade body has inner chamber, described inner chamber perisporium is a reflective surface, described inner chamber is served as reasons axially near the inner of led light source to axially being the tubaeform of divergent shape gradually away from the outer end of led light source, described inner chamber perisporium is in circumferentially being divided into some reflection subregions, and the axial cross section of described each reflection subregion has the curvature of protruding towards the inner chamber radial center.Principle of reflection according to spot light, the flared structure that the utlity model has some reflection subregions can be so that shine the light of surface of internal cavity and the outside that heat more is reflected to lampshade, make the actual light efficiency of LED lighting device increase, and reduce heat and in lampshade, assemble.
Further, in above-mentioned LED lampshade, described reflection subregion surface is provided with nano mirror plated film layer.Nano mirror plated film layer can be by sputtering method the nano particle plating to be located at lampshade chamber body perisporium to form.The light reflectivity of nano mirror plated film layer and heat reflectivity are all very high, have further reduced the absorption of light and heat amount in lampshade, make that the actual light efficiency of LED lighting device is higher, and heat energy more projects area of illumination.In addition, except the strong reflection of light and heat amount, nano mirror plated film layer has " lotus-effect " of nanometer, has self-purification function, is difficult for accumulation dust steam, more can effectively prolong the service life of LED lighting device.
Further, in above-mentioned LED lampshade, in the axial cross section of described reflection subregion, the curvature of close inner chamber the inner is less than the curvature near the inner chamber outer end.The reflecting surface of reflection subregion formation can better and reflex to the lampshade outside with light like this.
The utility model advantage is:
1, the utility model is by the lampshade inner chamber reflecting surface optical curvature design of improvement, angle of reflection after making light that led light source sends and heat shine on the reflecting surface is bigger, thereby light and heat more can be reflected to the lampshade outside, improve the actual light efficiency of LED lighting device and reduced the gathering of heat in lampshade, reduce LED lighting device element Yin Gaowen and the possibility of aging infringement, prolonged its service life.
2, the utility model is provided with nano mirror plated film layer at reflecting surface, and it has high reflectance to visible light and Thermal Infra-Red, makes light and heat further to give and reflects lampshade more.In addition, this nano mirror plated film layer has lotus-effect, has further prolonged the service life of LED lighting device.
Description of drawings
Fig. 1 is the perspective view of the utility model specific embodiment;
Fig. 2 is the front view of the utility model specific embodiment;
Fig. 3 is the vertical view of Fig. 2.
Wherein: 1 lampshade body; 2 inner chambers; 21 the inners; 22 outer ends; 23 reflection subregions.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described:
Embodiment: as shown in Figures 1 to 4, a kind of LED lampshade, comprise lampshade body 1, described lampshade body 1 has inner chamber 2, described inner chamber 2 perisporiums are reflective surface, described inner chamber 2 is served as reasons axially near the inner 21 of led light source to axially being the tubaeform of divergent shape gradually away from the outer end 22 of led light source, and described inner chamber 2 perisporiums are in circumferentially being divided into some reflection subregions 23, and the axial cross section of described each reflection subregion 23 has the curvature of protruding towards inner chamber 2 radial center.
Described reflection subregion 23 surfaces are provided with nano mirror plated film layer.
The utility model correction the optical curvature of lampshade inner chamber reflecting surface, and nano mirror plated film layer is set at reflecting surface, reduced the heat of in lampshade, assembling because of reflection shield, light and heat are more reflexed to the light irradiated region, when improving the actual light efficiency of LED lighting device, prolonged the service life of LED lighting device.
