Description

Suspended ceiling with relatively thin thickness

Technical Field

The utility model belongs to elevator car furred ceiling field especially relates to a thickness is thinner furred ceiling for elevator car.

Background

The lamps and lanterns of illumination usefulness in the elevator car are installed inside the furred ceiling usually, and the below of lamps and lanterns is equipped with the light-passing board of being connected with the furred ceiling bottom surface, and the effect of light-passing board makes lamps and lanterns not expose, improves the aesthetic measure of furred ceiling. The existing lamp generally adopts a fluorescent lamp tube, the fluorescent lamp tube is fixed on a top plate of the suspended ceiling through a lamp holder, if the light of the fluorescent lamp tube is required to be fully dispersed and a shadow is not formed on a light-transmitting plate, the distance between the fluorescent lamp tube and the light-transmitting plate is required to be ensured to be more than 9cm, the thickness of the suspended ceiling is difficult to be thinned, and the thickness of the whole suspended ceiling is very thick.

The smaller the distance between the lamp and the light-transmitting plate is, the thinner the thickness of the suspended ceiling is, but the more obvious the lamp shadow on the light-transmitting plate is, the attractiveness of the suspended ceiling can be reduced, and the attractiveness of the lift car can be reduced; the distance between lamps and lanterns and the light-passing board is big more, and lamps and lanterns shadow on the light-passing board is just more unobvious, but the thickness of furred ceiling is just thicker, and furred ceiling thickness can crowd the car space, reduces the inside height of car, makes the passenger feel oppressed, and the comfort level of car is just relatively poor.

In order to take account of the attractiveness and comfort of the lift car, the overall thickness of the conventional suspended ceiling is generally kept about 12cm, although the distance between a lamp and a light-transmitting plate cannot reach more than 9cm, lamp shadows are left on the light-transmitting plate of the suspended ceiling, but the lamp shadows are not too obvious, and the influence on the attractiveness of the lift car is not too great; also enable the thickness of furred ceiling simultaneously and be unlikely to too big, crowd and account for the space on the more height of car, be unlikely to too big to the comfort level influence of car. It is obvious that the existing suspended ceiling can not make the car beautiful and comfortable.

Therefore, the existing suspended ceiling has the defect that the attractiveness and comfort of the lift car cannot be better.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a thickness thinner furred ceiling. The utility model has the advantages of make the car beautifully spend and the comfort level is all better.

The technical scheme of the utility model: a suspended ceiling with a thin thickness comprises a square top plate, wherein side plates formed by bending are arranged at the edges of the periphery of the top plate, the side plates are L-shaped, a partition plate is arranged below the top plate, a first lighting unit is arranged at the top of the partition plate, light-passing plates are arranged on two sides of the partition plate, second lighting units connected with the top plate are arranged on two sides above the partition plate, and reflecting films attached to the bottom surface of the top plate are arranged on two sides of each second lighting unit; the structure of the first lighting unit and the structure of the second lighting unit both comprise elongated aluminum substrates, LED lamp beads which are connected in series are arranged along the length direction of the aluminum substrates, and fisheye-shaped lenses are packaged on the LED lamp beads.

In the suspended ceiling with the thin thickness, the section of the partition plate is I-shaped, and one end of the light-transmitting plate is inserted into the lateral groove of the partition plate.

In the suspended ceiling with the small thickness, the side plate is provided with a plurality of first heat dissipation holes close to the top plate and a plurality of second heat dissipation holes close to the light-transmitting plate, and the first heat dissipation holes and the second heat dissipation holes are arranged in a staggered mode in the horizontal direction.

In the suspended ceiling with the small thickness, the first heat dissipation holes and the second heat dissipation holes are internally provided with insect-proof screen cloth.

In the suspended ceiling with the thin thickness, the top surface of the light transmission plate is a frosted surface.

Compared with the prior art, the utility model discloses the aluminium base board snap-on of the small and accessible of LED lamp pearl on the first lighting unit (being equivalent to current fluorescent tube) is on the roof of furred ceiling, and overall height is less, can not leave under the prerequisite of shadow on the light-passing board guaranteeing, can reduce furred ceiling thickness. The utility model discloses a second lighting unit is polished to the roof earlier, and light compensates on the light-passing board after the reflection of launching membrane to make the luminous flux of each region on the light-passing board comparatively unanimous, can weaken or eliminate the shadow that first lighting unit formed on the light-passing board; the fish-eye lens on the LED lamp bead can increase the beam angle of light, so that the light is more fully diffused, and shadows formed on the light-transmitting plate by the first lighting unit can be weakened or eliminated; the top surface of the light-transmitting plate is frosted, so that light rays are subjected to diffuse reflection when passing through the light-transmitting plate, and shadows formed on the light-transmitting plate by the first lighting unit can be weakened or eliminated; after the shadow on the light transmitting plate is weakened or eliminated for many times, even if the distance between the first lighting unit and the light transmitting plate is shortened, the shadow is not left on the light transmitting plate, and the thin suspended ceiling can be made again. Through the test of drawing a design, the utility model discloses a whole thickness still can not leave the shadow on the light-passing board again after reducing to 6.4 cm.

Because no shadow is arranged on the light-passing board of the utility model, the utility model has better aesthetic degree, and the aesthetic degree of the car can be improved; because the utility model discloses a thickness is thinner, can not crowd the space on the more height of car, and height in making the car is higher, and the passenger can not feel oppressed, and the comfort level of car is also better.

Therefore, the utility model has the advantages of it is all better to enable pleasing to the eye degree of car and comfort level.
