Abstract

The utility model relates to a lighting grid desk lamp with a directional light source, which is composed of a lamp base 1, a lamp bracket 3 and a bulb holder 6 which is composed of a lamp shade 7, a reflecting shade 8 in the lamp shade, a luminary 9 and a grid plate 10 on the opening of the lamp shade. Through the cooperation between the reflecting shade 8 and the grid plate 10, the desk lamp restricts the light ejecting angle from the bulb holder so as to achieve the function of directional lighting, eliminates direct glare to eyes from common desk lamps, and even eliminates a light source image in a computer screen and reflected glare to protect eyes so that the eyes of users do not feel tired. Besides, the concentration of the light source is favorable for the purposes of energy saving and electricity saving.

Description

Directive property light illumination grid desk lamp

The utility model relates to a kind of lighting lamp, is specifically related to a kind of directive property light illumination desk lamp.Belong to a mouthful normal technical field of living goods.

Existing desk lamp is made up of lamp socket, lamp bracket and lamp holder.Lamp holder includes the illuminator in lampshade and the lampshade.This desk lamp belongs to the astigmatism light source, and omnidirectional illumination functions produces direct glare to user's eyes easily, can only do general purpose illumination usually.Along with the PC universalness, increasing computer user notices the direct glare of common desk lamp and the reflected glare that shape is risen on computer screen thereof, makes eyes tired easily, causes headache, influence healthy, even increase error of performance.Concerning long-term computer user, eye fatigue is maximum healthy crisis.General desk lamp is owing to belong to the astigmatism light source, and its light source shadow appears on the computer screen inevitably, causes dazzling reflected glare.And because light is not concentrated, a part of light shines on the computer screen, makes the fluorescent screen be canescence, reduces the definition of fluorescent screen.So,, be one to press for the problem of solution from the direct glare of light fixture and computer screen reflected glare to light fixture.

The purpose of this utility model is to provide a kind of directive property light illumination desk lamp that the directional lighting function is arranged, and eliminates direct glare and the indirect reference dazzle harmful to eyesight.

The utility model is achieved in that a kind of directive property light illumination grid desk lamp, comprises lamp socket, lamp bracket and lamp holder.Lamp holder includes lampshade and places the interior illuminator of lampshade, is characterized in being equipped with reflection shield on the lampshade internal face, is equipped with flase floor on the lampshade mouth, by reflection shield and flase floor combination, limits the angle of illuminator light ejaculation, reaches the purpose of directional lighting.

Compare with common desk lamp, the utlity model has following advantage:

1, except light institute illumination direction, other angle and zone are not influenced by light, so eliminated the direct glare that general desk lamp produces eyes.

2, have the directional lighting function, avoid the pollution of light.Other people are not subjected to do sorrow to use desk lamp can make on every side as a people; Light only shines on keyboard or other objects that need shine during operating computer, and do not shine directly on the computer screen, make screen not be subjected to astigmatism to do sorrow, can prevent that light source from directly mirroring screen and producing strong dazzle, can prevent that also the shadow from directly mirroring screen and producing dazzle and disturb.

3, light source is concentrated because the cooperation of reflection shield and flase floor is arranged, and makes light source more concentrated, increases regional luminance, reaches the purpose of electricity saving and energy saving.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the A-A cutaway view of Fig. 1.

Fig. 3 is that the B of Fig. 1 is to view.

Below in conjunction with accompanying drawing the utility model being done one describes in detail:

As Fig. 1, the utility model is a kind of directional lighting grid (directive property light illumination) desk lamp, and it is made up of lamp socket 1, lamp bracket 3 and lamp holder 6.3 devices of lamp socket 1 and lamp bracket have rotatable parts 2, and lamp bracket 3 middle devices have rotatable parts 4, and 6 devices of lamp bracket 3 and lamp holder have rotatable parts 5.

As Fig. 2, lamp holder 6 is made up of lampshade 7, reflection shield 8, illuminator 9 and flase floor 10.Reflection shield 8 places on lampshade 7 internal faces, and illuminator 9 is installed in the lampshade 7, and illuminator 9 is one or more bulbs or fluorescent tube.Flase floor 10 places on the lampshade 7 lampshade mouths.

As Fig. 3, flase floor 10 each grid 11 are of a size of: dark (5～50) * (5～50) * (3～50) mm of the wide * of long *, also can be (10～25) * (10～25) * (5～15) mm, and be preferably (10～20) * (10～20) * (8～12) mm.

Flase floor 10 can be used plastic production, and the surface is coated with silver or other silvery white metal.Also the available metal material is made, as the aluminum alloy thin slice.

Reflection shield 8 can be made by metal or plastic material, and the surface is coated with silver or white, also can be replaced by the lampshade inwall.
