Description

A kind of collapsible LED screen

Technical field

The utility model relates to the lamp ornaments lighting field, especially relates to a kind of collapsible LED screen.

Background technology

At present; Existing LED ornament lamp is of a great variety, many utility model persons is arranged in the recent period in order to break through the limitation of existing lamp decoration, and utility model goes out meshwork lamp or braiding lamp & lantern product; Decorate or it is attached on the flexible plate but this type of lamp decoration has to hang separately; On base plate, draw out required any pattern, can lamp decoration be combined on this flexible plate, make whole motif have more abundant variation; Dwindle the volume that its material occupies though the lamp string can be reeled, the light flash variation of its whole meshwork lamp can only be leaned on different flicker paces of change and decided.

In order to overcome the deficiency of above-mentioned technology; Someone designs a kind ofly has the lamp string in several loops to be configured to whole lamp decoration wire side alternately; These individual lamps strings can be because of the selectivity layout of its several independent lamp pearl; And these mutual selectivity layouts of each individual lamps string and form various literal that can arbitrarily design or pattern, though the mutual selectivity layout of its meshwork lamp and form various literal that can arbitrarily design or pattern, owing to its pattern or literal are to pre-set figure by the lamp string; And its figure that pre-sets is that a figure is a loop; When showing another figure, just use lamp string,, and when not pre-setting the figure that needs to show, then just can not show in use so waste material, cost are high less than previous figure.
