Abstract
The utility model relates to a semi-direct illumination device. The semi-direct illumination fluorescence light fitting comprises a light casing, a light seat, a light tube and electrical apparatus elements, wherein, an opening of the light casing is downward; and the back of the light casing is provided with a transmission trough or a transmission hole structure. The utility model makes one light tube provide direct and indirect illumination light at the same time, effectively reduces attenuation of upward beam, lightens the accumulation of dust, and the like on a light source and the transmission trough or the transmission hole at the same time, has self-cleaning function, has simple structure and simple die sinking, and reduces the cost of entire light fitting.
Description
[technical field]
The utility model relates to a kind of semidirect illumination device.
[background technology]
Light fixture can be divided into direct illumination according to the luminous intensity distribution form, indirect lighting, semidirect illumination, semiindirect lighting etc. (Fig. 1).
Wherein, in the lamp device of semidirect illumination, have 60%～90% only to shine directly on the working face downwards, and all the other light of 10%～40% upwards shine on the smallpox ceiling, as indirect lighting, one side illuminates the smallpox ceiling, reflexes on the other hand to be used for softening shade on the working face.
Common semidirect illumination type light fixture is the semiclosed translucent lampshade regulation and control with the cover mouth down, and the light cover with 60～90% is to daylighting face, in the space around simultaneously all the other illumination being mapped to.The trnaslucent materials of light fixture adopts semi transparent materials such as acrylic, plastics, lucite usually, can make light more soft, but these materials are bigger to the decay of light, and the light transmission of the material decay that descends as time passes is even more serious, and influence is to the intensity of glazed thread and then influence the indirect lighting effect.On the other hand, meetings such as the dust in the use are constantly gathered on light fixture top, and light transmission further descends.
In the closed lighting that this external normally used metal material is made, the lampshade back side is complete closed, and any slit at the light fixture back side all belongs to " light leak " according to experience in the past.
[utility model content]
This is practical to aim to provide an a kind of tubes can provide directly and indirect lighting light simultaneously, can effectively reduce the decay of light fixture to the illumination beam that makes progress itself, and has the semidirect illumination fluorescent lighting fixture simple in structure of self-cleaning function simultaneously.
The purpose of this utility model is achieved by following technical proposals.
Semidirect illumination fluorescent lighting fixture described in the utility model comprises lamp housing, lamp socket, fluorescent tube and electric elements, and wherein Open Side Down for lamp housing, and the lamp housing back side is provided with light tank or loophole structure.
Described light tank or loophole be located at fluorescent tube directly over; Preferred light tank is parallel with fluorescent tube or vertical.
Further preferred light tank is for being located at directly over the fluorescent tube, and with the fluorescent tube parallel rectangular, its length of side perpendicular to fluorescent tube is 0.1～2.6 centimetre.
When using the T8 fluorescent tube, light tank is 0.1～2.6 centimetre perpendicular to the length of side of fluorescent tube.
When using the T5 fluorescent tube, light tank is 0.1～1.5 centimetre perpendicular to the length of side of fluorescent tube.
Further preferably, the lamp housing back side is provided with two discontinuous light tanks; Most preferably be two or three.
In addition, described light fixture also comprises the reflection grid.
Light fixture described in the utility model, by light tank/pore structure is set, with a part of light that light source sends, directly upwards projection wherein owing to without any the material that shuts out the light, has therefore reduced the damping characteristic to light beam effectively as the light of indirect lighting; Light tank/hole passage of providing light source and light fixture electrical equipment heat up to distribute simultaneously, so air is from lower to upper by light tank/hole, helps to alleviate dust etc. on light source and the accumulation in light tank/hole; In addition, light tank/hole is directly to open at the light fixture back side, and simple in structure, die sinking is simple and easy, has reduced whole light fixture cost.

[specific embodiment]
Below in conjunction with accompanying drawing the utility model is further described.
In the drawings, the semidirect illumination fluorescent lighting fixture comprises lamp housing 1, lamp socket, fluorescent tube 2, electric elements and reflection grid 5, and Open Side Down for lamp housing 1, and be provided with light tank 4 on the lamp housing back side 3, also can adopt other suitable shapes such as loophole.Like this, 40%～10% indirect lighting light beam throws by light tank 4, and 60%～90% direct illumination light beam throws by the reflection grid.
When using T8 fluorescent tube 2, light tank 4 is 0.1～2.6 centimetre perpendicular to the length of side of fluorescent tube 2, and the luminous flux of the indirect light of corresponding light fixture output is about the 1.2%-32% of light fixture total light flux;
When using T5 fluorescent tube 2, light tank 4 is 0.1～1.5 centimetre perpendicular to the length of side of fluorescent tube 2, and the luminous flux of the indirect light of corresponding light fixture output is about the 2.1%-32% of light fixture total light flux.
