Abstract

The utility model relates to a light emitting diode (LED) lamp, which mainly comprises a spherical LED lamp cover, an LED chip with high power, a circuit board and a lamp socket. The LED lamp cover comprises a light-transmitting layer at the upper end and a reflecting layer at the lower end, wherein the lowest position of the reflecting layer is located at the position of a lamp cover opening, the highest position of the reflecting layer is located above the largest diameter of the lamp cover, and the height of the reflecting layer is 1.2 times of the length of the largest diameter of the cover lamp. Due to the fact that the height of the reflecting layer is particularly limited, the reflecting layer can reflect rays emitted by the LED chip to the position of the light-transmitting layer at the upper end as far as possible, thereby increasing the luminance of the light-transmitting layer of the lamp cover and further improving the luminance of the LED lamp or selecting an LED chip with small power to achieve the light-emitting effect.

Description

A kind of LED light fixture

Technical field

The utility model relates to a kind of light fixture, especially relates to a kind of LED light fixture.

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 LED light fixture, 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 LED light fixture, mainly comprise the LED lampshade of spheroidal, one piece of high-power LED chip, circuit board and lamp socket, this LED lampshade comprises the photic zone of upper end and the reflecting layer of lower end, described reflecting layer lowest part is positioned at lampshade mouth place, described reflecting layer highest point is positioned at the top of lampshade maximum gauge, and the height in described reflecting layer is 1.2 times a lampshade maximum gauge length.

Scribble ZnS base nano fluorescent bisque at described euphotic inner surface or on described high-power LED chip surface.

Further, described reflecting layer is the metal aluminium lamination.

This LED light fixture is compared with the common LED lamp tool, has following beneficial effect:

(1) the utility model is owing to make above-mentioned detailed qualification to the height in reflecting layer, thereby the reflecting layer light that led chip can be sent reflexes to the photic zone place of upper end as much as possible, and can increase the euphotic brightness of lampshade, further improve the LED lamp brightness, perhaps can select low power relatively led chip just can realize illuminating effect.

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

10-LED lampshade; 11-photic zone; 111-lampshade maximum gauge; 112-reflecting layer and photic zone junction; 12-reflecting layer; 13-lampshade mouth; 14-high-power LED chip; 141-ZnS base nano fluorescent bisque.

The specific embodiment

Below in conjunction with Fig. 1 to Fig. 3, the utility model is described further:

A kind of LED light fixture, mainly comprise the LED lampshade 10 of spheroidal, one piece of high-power LED chip 14, circuit board and lamp socket, this LED lampshade 10 comprises the photic zone 11 of upper end and the reflecting layer 12 of lower end, reflecting layer 12 lowest parts are positioned at lampshade mouth 13 places, reflecting layer 12 highest points are positioned at the top of lampshade maximum gauge 111, and the height in reflecting layer 12 is 1.2 times lampshade maximum gauge 111 length.Because the height in reflecting layer 12 is made above-mentioned detailed qualification, thereby reflecting layer 12 light that led chip 14 can be sent reflexes to photic zone 11 places of upper end as much as possible, thereby can increase the brightness of lampshade photic zone 11, further improve the LED lamp brightness, perhaps also can select low power relatively led chip just can realize illuminating effect.

In addition, scribble ZnS base nano fluorescent bisque 141 at the inner surface of photic zone 11 or on high-power LED chip 14 surfaces.Nano level ZnS base fluorescent powder can absorb behind the light that LED sends uniformly and activate the ZnS base fluorescent powder, makes through the light of photic zone 11 brightlyer, thereby can use lower powered relatively led chip under the requirement of same brightness.

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.
