Description

Inflatable lampshade structure for work lights

The invention relates to a lampshade structure applied to a work lamp. The technical content relates to a fan that uses a heat-dissipating fan of the light-emitting component to blow air to the soft light-transmissive cover, so that the light-transmissive cover is inflated, and not only is not easily damaged by collision, but also can be damaged after the light-transmitting cover is deflated. The bundle is reduced in size for easy storage.

Generally, in the construction site or outdoor occasions, it is easy to cause safety due to insufficient light caused by indoor or nighttime environment. Therefore, the staff will provide sufficient illumination by using work lights, floodlights, etc., in order to smoothly carry out the work.

The inventor has developed a TWI434008, JP 3177650 LED lighting device, as shown in the first figure, the device includes a tripod, and a lighting assembly 1a disposed on the tripod, wherein the lighting assembly 1a includes a The bracket 100a on the tripod, the LED illuminating board 102a disposed on the bracket 100a, and the cooling fan 101a disposed under the bracket 100a, the cooling fan 101a can be blown upward to the back of each LED illuminating board 102a to be forced The heat is dissipated, and the plurality of LED illuminating plates 102a can adjust the irradiation angle on the bracket 100a, and can be used as a work light in a disaster relief place, a work place or the like in conjunction with the stand.

In the known technology, in order to avoid the problem that the light projected by the light-emitting component is too concentrated, the visual force of the worker is easily damaged at night, and the damage is not easily damaged, the patent numbers JP4381704B2, CN101646900A, and US7264382 are disposed on the periphery of the light-emitting component. The inflatable soft lamp cover can spread the light evenly when the work lamp is used, and it is not easy to collide and damage. When the work lamp is not used, it can be conveniently stored.

The above-mentioned known inflatable soft lampshade is not much used in use. The problem, but after careful study of its structure, it is found that the light of these known techniques is uniformly diffused in all directions, failing to uniformly illuminate in the same direction, for example, when the staff performs ground engineering and needs to strengthen the ground working illumination, the upward projection The light disperses the intensity of the light.

Moreover, the lampshades of the prior art are formed into a round shape after being inflated, so the structure is composed of three pieces of upper, middle and lower pieces, and the process of connecting the upper, middle and lower pieces of the cloth in the sewing seam. It is relatively difficult in the middle, especially after the sewing of the upper cloth and the middle cloth is completed, the middle cloth has basically formed a cylindrical shape, and it is very difficult to sew the lower cloth at this time. Moreover, the upper and lower cloth sheets which are in a ring shape are also zippered along the inner wall to be assembled on the periphery of the light-emitting component, and the manufacturing process is cumbersome.
