Description
Technical field
The present invention relates to LED technology field.
Background technology
LED silk of the prior art, need die bond bonding wire on substrate in process of production, production process is comparatively complicated, be difficult to extensive high efficiency production, in addition easily produce loose contact phenomenon by the connected mode of gold thread between each LED chip or do not weld gold thread phenomenon occur, cause the inefficacy of LED chip.
Summary of the invention
In order to overcome the deficiency that prior art exists, the object of the present invention is to provide a kind of LED bulb from ballast flexible LED filament and formation thereof completely newly, significantly can increase the convenience of use.
For reaching above object, the invention provides a kind of from ballast flexible LED filament, comprise flexible base board, on described flexible base board, preparation has connection line, the end positions of described connection line is formed with electrode, described connection line in-between the electrodes position is formed with multiple pad, one flip LED chips is installed between often pair of pad, described flexible base board and the outer cover of LED chip are equipped with sleeve pipe or injection moulding around being enclosed with colloidal silica, be provided with in described connection line from ballasting module, for the civil power of input being converted to the DC constant flowing power of described flip LED chips.
Further improvement of the present invention is, the transparent state of described flexible base board.
Further improvement of the present invention is, described flexible base board comprises FPC or slim PCB.
Further improvement of the present invention is, also comprises battery supply module, and the Power convert for being provided by battery is DC constant flowing power; And selection control module, for switching between ballasting module, battery supply module described as requested.
Further improvement of the present invention is, also comprises automatic adjustment module, for according to filament length and the automatic regulation output voltage of core number and electric current.
Further improvement of the present invention is, also comprises light-adjusting module, for environmentally brightness adjustment LED chip output intensity.
According to a further aspect in the invention, provide a kind of LED bulb, comprise hair bubble, lamp holder, be arranged on described hair bubble inner as above from ballast flexible LED filament and with the use of support member, described is bent predetermined angular to present predetermined moulding from ballast flexible LED filament.
Further improvement of the present invention is, described lamp holder inside arranges the charging module of battery and correspondence.
Further improvement of the present invention is, described battery rechargeable lithium battary, lithium polymer battery.
Further improvement of the present invention is, described hair bubble is G type, C type, S type, A type or PS type, and the diameter of described hair bubble is 35mm-125mm.
The invention has the beneficial effects as follows and optimize product structure, before employing flip-chip can prevent, gold thread is bent the generation of disconnected phenomenon, cost low (need not gold thread be beaten), good heat dissipation, formal dress sticks with glue and upside-down mounting tin cream, that can do is thinner, in addition owing to have employed the technique of sleeve pipe or injection moulding (molding), mass production can be realized.
Accompanying drawing explanation
Accompanying drawing 1 is according to the schematic diagram from ballast flexible LED filament of the present invention;
Accompanying drawing 2 is the schematic diagram according to LED bulb of the present invention.
Detailed description of the invention
Below preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
