Description

A kind of grid light fixture

[technical field]

The utility model relates to a kind of grid lighting device that has make progress light tank and lens.

[background technology]

Light fixture is a kind of light source that is used to hold and protect, and the light that the control light source sends is to the power of its surrounding space projection and the device of direction.

The grid light fixture is that the various diameter straight tubes of a kind of employing or other shape fluorescent lamps are as light source; In the lamp body lower opening; And the reflection grid is set at opening part; Strengthened when on the one hand being used to make light to throw downwards as far as possible, strong and weak controlled in different angles when light is throwed downwards, thus form different distribution curve fluxs.Simultaneously, the light fixture shielding angle can be formed, dazzle can be reduced perpendicular to the grid of fluorescent tube.The light of grid light fixture is through opening projection, so light all is incident upon in the lower space of horizontal plane under the light fixture, and any slit at the light fixture back side all belongs to " light leak " according to experience in the past.

In a space, when light directly projected an object, when not considering that reflection exists, object plane was illuminated to ray surface, and ray surface is not illuminated dorsad, forms various shades.When object itself need be showed, various shades were strengthened the third dimension of object and are given top priority to what is the most important.Light beam projection with narrower reduces various unnecessary reflections, can form the various effects that help showing.

In a space, when light shone an object from each different directions, the shade of object reduced.In various working spaces, ray cast is convenient to human eye and is seen these lip-deep contents clearly to reading on surface and the writing surface, and at this moment these surperficial light more evenly are easy to human eye more and see that the existence of various shades and contrast is disadvantageous.Therefore in this space, need reduce contrast as far as possible.Light in the space both direct projection arrives working face, and when passing through the reflection arrival working face of smallpox and wall again, various shade contrasts is just by effective minimizing.

Grille lamp is to adopt a kind of very widely light fixture in the various working spaces; Its architectural feature makes it can directly provide the light with batswing tab luminous intensity distribution characteristic of the work of being beneficial to working face; Also can to working face illumination be provided, thereby be highly suitable for the workplace through wall reflection.But because the light of existing Grille lamp all is projeced into the below of light fixture place horizontal plane, even under the situation of lifting, also can't light be provided to ceiling.

Simultaneously; The light that fluorescent tube sends in the Grille lamp is to the direction projection of 360 degree; Light direct projection downwards and that reflect through reflection unit is merely a part wherein; Light to the lamp body back side and internal transmission can not be reflected fully, and this part light can not be utilized, and has reduced the efficient of light fixture.

Therefore, if offer light tank at the back side of Grille lamp, let the light that was wasted originally throw to ceiling, these light illuminate the various contrasts that ceiling reduces working space and working face, improve illuminating effect on the one hand, have also improved the efficient of light fixture simultaneously.

The light at the Grille lamp back side, if only through the light tank projection, its range of exposures can be the narrower scope in light fixture top.

[utility model content]

This is practical to aim to provide a kind of grid light fixture; Can keep Grille lamp as the desirable lighting in workplace; Provide for working face under the prerequisite of characteristic of direct illumination of batswing tab luminous intensity distribution characteristic; Make this type light fixture that light beam upwards can be provided under the lifting condition, thereby further improve the illuminating effect of workplace.Simultaneously,, obtain utilizing, improved the efficient of light fixture through upwards throwing with the light that originally in lamp body, slatterns.

The purpose of the utility model is achieved through following technical proposals:

A kind of grid light fixture of the utility model comprises lamp housing, lamp socket, and fluorescent tube and reflection grid, Open Side Down for lamp housing, and the lamp housing back side is provided with light tank, and described light fixture also is provided with lens above fluorescent tube.

Wherein preferably, described light tank is to replace with loophole.

Further preferably, described lens be arranged on fluorescent tube directly over.

More preferably, described lens be arranged on fluorescent tube directly over.

Perhaps more preferably, described lens are arranged on the top of light tank or are arranged on the below of light tank or are arranged in the light tank.

Further preferably, the projection of described lens on fluorescent tube plane of living in is parallel with fluorescent tube or vertical.

Perhaps further preferably, the projection of described light tank on fluorescent tube plane of living in is parallel with fluorescent tube or vertical.

In above-mentioned further preferred embodiment, can preferably described lens and light tank all be set to rectangle.And more preferably the area of lens is set to the area less than the lamp housing back side.

The described light fixture of the utility model; Through the lamp body back side light tank and lens are set; With the upwards projection of a part of light (IDL) that light source sends, for ceiling provides illumination, these shine the reflection of the light of ceiling through ceiling; Can effectively reduce the various contrasts of working face and working space, thereby improve the illuminating effect of workplace.When light passed through the light tank at the lamp body back side, process was installed in the refraction of the lens of light tank, further to the spatial diffusion at the lamp body back side, had increased the scope and the uniformity of irradiation.Simultaneously, the light major part that this part makes progress is originally to the lamp body internal transmission, and the light that can not be utilized through the light tank lens arrangement, is used again, thereby has improved the efficient of light fixture.In addition, light tank and lens are directly to offer and be installed in the light fixture back side, and are simple in structure, reduced whole light fixture cost.
