Abstract

The utility model relates to a low power light-emitting diode (LED) lampshade, which comprises a spherical light-transmitting layer and a columnar reflecting layer, wherein a taper angle formed by the sphere center of the spherical light-transmitting layer and the connecting part of the spherical light-transmitting layer and the columnar reflecting layer is 120 degrees. According to the lower power LED lampshade, since the taper angle formed by the sphere center of the spherical light-transmitting layer and the connecting part of the spherical light-transmitting layer and the columnar reflecting layer is 120 degrees, light rays sent out by an LED chip can be reflected to the spherical light-transmitting layer at the upper end of the columnar reflecting layer as much as possible by the columnar reflecting layer, so the brightness of the spherical light-transmitting layer can be increased and the brightness of an LED lamp can be further improved.

Description

A kind of low-power LED lampshade

Technical field

The utility model relates to a kind of lampshade, especially relates to a kind of low-power LED lampshade.

Background technology

LED is had the following advantages as lighting: the first, the LED consumed energy reduces 80% with the incandescent lamp of light efficiency; The second, LED does not have poisonous metal mercury, can not pollute environment; Three, the optical purity height that sends of LED.

But, set up in current opinion under the background of low-carbon (LC) society, still need to further improve for the good LED of energy-efficient performance, the effective lighting that makes LED send is many as much as possible, invalid or unemployed light reduces as far as possible, thereby need further improve lampshade, improve brightness of illumination as far as possible.

Summary of the invention

The utility model has designed a kind of low-power LED lampshade, and the technical problem of its solution is that existing lampshade fails to convert effective lighting to the light of LED emission is maximized.

In order to solve the technical problem of above-mentioned existence, the utility model has adopted following scheme:

A kind of low-power LED lampshade comprises spherical photic zone and cylindricality reflecting layer, and the cone angle that the euphotic centre of sphere of described sphere and described spherical photic zone and junction, described cylindricality reflecting layer form is 120 °.

Further, a plurality of light-emitting diode chip for backlight unit are arranged on described spherical photic zone and junction, described cylindricality reflecting layer.

Further, the euphotic inner surface of described sphere scribbles ZnS base nano fluorescent bisque.

Further, the euphotic material of described sphere is plastics or glass.

Further, described cylindricality reflecting layer is the metal aluminium lamination.

This low-power LED lampshade is compared with the common LED lampshade, has following beneficial effect:

(1) the utility model is owing to the cone angle with the euphotic centre of sphere of sphere and spherical photic zone and the formation of junction, cylindricality reflecting layer is 120 °, thereby the cylindricality reflecting layer light that light-emitting diode chip for backlight unit can be sent reflexes to the spherical photic zone place of upper end as much as possible, thereby can increase spherical euphotic brightness, further improve the LED lamp brightness.

(2) the utility model is owing to scribble ZnS base nano fluorescent bisque at the euphotic inner surface of sphere, nano level ZnS base fluorescent powder can absorb behind the light that LED sends uniformly and activate the ZnS base fluorescent powder, make through spherical euphotic light brighter, thereby can under the requirement of same brightness, can use lower powered relatively led chip.

Description of reference numerals:

11-spherical photic zone; 12-cylindricality reflecting layer; 13-plug; 14-light-emitting diode chip for backlight unit; 15-circuit board; 16-lamp socket; A-cone angle.

The specific embodiment

Below in conjunction with Fig. 1, the utility model is described further:

As shown in Figure 1, a kind of low-power LED lampshade, comprise spherical photic zone 11 and cylindricality reflecting layer 12, the cone angle A that the centre of sphere of spherical photic zone 11 and spherical photic zone 11 and 12 junctions, cylindricality reflecting layer form is 120 °, and a plurality of light-emitting diode chip for backlight unit 14 are arranged on spherical photic zone 11 and 12 junctions, cylindricality reflecting layer.Thereby cylindricality reflecting layer 12 light that light-emitting diode chip for backlight unit can be sent reflexes to the spherical photic zone place of upper end as much as possible, thereby can increase spherical euphotic brightness, further improves the LED lamp brightness.

As shown in Figure 2, the inner surface of spherical photic zone 11 scribbles ZnS base nano fluorescent bisque.Nano level ZnS base fluorescent powder can absorb behind the light that LED sends uniformly and activate the ZnS base fluorescent powder, makes through euphotic light brightlyer, thereby can use lower powered relatively led chip under the requirement of same brightness.

The material of spherical photic zone 11 is plastics or glass.

Cylindricality reflecting layer 12 is the metal aluminium lamination.The metal aluminium lamination can accomplish to reduce as much as possible the reflection consumption of luminous energy.

In conjunction with the accompanying drawings the utility model has been carried out exemplary description above; obvious realization of the present utility model is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted method design of the present utility model and technical scheme to carry out; or design of the present utility model and technical scheme are directly applied to other occasion without improving, all in protection domain of the present utility model.
