## Abstract

A foldable soft box includes a housing in which a hollow portion is formed in the central part thereof, a plurality of insertion grooves are radially formed on the front side thereof, and a rotation space is formed on the inner side thereof; a plurality of support bars which are rotatably connected to the housing such that the plurality of the support bars are selectively inserted into the insertion grooves; a rotary control unit which is rotatably disposed in said turning space; and a lamp fixing unit which is coupled with said hollow portion, and fixes a light-emitting lamp.

## Claims

### Claim 1

A foldable soft box with lamp fixing unit that fixes the light-emitting lamp wherein it is connected in a detachable manner at the rim of the hollow portion comprising:
a housing in which a hollow portion is formed in the central part wherein a plurality of insertion grooves are radially formed on the front side with turning space is located at the inner part thereof;
a rotary control unit which is rotatably disposed in said turning space, and
wherein the rotary control unit has hooks which are elastically supported by elastic springs that are disposed in guide grooves formed on the inner side of said housing and selectively control said support bars inserted into said insertion grooves.

### Claim 2 (depends on 1)

The foldable soft box of claim 1 wherein the rotary control unit is put in place in order to move in circumferential direction of the turning space wherein the rotating part with circular shape that had been equipped to be exposed at the outer part of the housing, and it rotates according to the rotating motion of the rotating part,
wherein it is formed with the hook extension part wherein the protruding hook is equipped.

### Claim 3 (depends on 2)

The foldable soft box of claim 2 wherein long hole is formed at the back part of the housing for the purpose of protruding knob to go through and rotate; and
wherein the rim of the long hole is equipped with protruding knob and protruding fixed knob in the opposite direction to be placed on the rim of the long hole.

### Claim 4 (depends on 1)

The foldable soft box of claim 1 wherein one side of the support bar and the housing are mutually connected by the elastic material wherein the folding action occurs when the support bar is freed from restriction.

### Claim 5 (depends on 1)

The foldable soft box of claim 1 wherein the lamp fixing unit consists of the base part wherein the rim of the installed hole is formed which corresponds to the front part of the lamp in the center wherein it is connected selectively in a detachable manner through the fastening part located at the back part of the housing; and,
wherein the hollow portion placed at both sides of the base wherein the high pressure screw is fastened to the fastening hole at the side of the hollow frame;
wherein the higher portion is inserted to hollow fixed part and fastened in a detachable manner and the support frame that had been designed to selectively fold in the fixed equipment which is installed in the lower part of the mounting post.
