Summary of the invention

In order to overcome the deficiency that prior art exists, the purpose of this utility model is to provide no dark space, a kind of terminal card neck two ends light emitting LED lamp strand, its entirely lighting and no dark space, two ends shadow.

For reaching above object, the utility model provides no dark space, a kind of terminal card neck two ends light emitting LED lamp strand, comprise the LED strand unit of one or more interconnection, each described LED strand unit comprises transparent substrates, described transparent substrates prepares multiple LED chip and connection line, the both side surface of described transparent substrates is coated with fluorescence silica gel layer, described connection line by LED chip electrical connection and two ends prepare respectively and have positive and negative electrode, described fluorescence silica gel layer to be covered in LED chip and to be exposed by positive and negative electrode, described positive and negative electrode be positioned at LED chip side and away from the both ends of transparent substrates, positive and negative support terminals supports LED strand unit and correspondence is pressed on positive and negative electrode.

Further improvement of the utility model is, described LED chip is flip-chip.

Further improvement of the utility model is, multiple described LED strand unit successively head and the tail is interconnected.

Further improvement of the utility model is, keeps predetermined angular between adjacent described LED strand unit.

According to another aspect of the present utility model, provide a kind of LED bulb, comprise hair bubble, lamp holder, power circuit, also comprise be arranged on the inner terminal card neck two ends as above no dark space light emitting LED lamp strand of described hair bubble and with the use of support member, described support member has several jack, and each described jack plugs connection with corresponding positive and negative support terminals respectively.

Further improvement of the utility model is, described power circuit comprises the light adjusting circuit for adjusting light intensity, and described light adjusting circuit and power circuit are wholely set on circuit boards.

Further improvement of the utility model 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 beneficial effects of the utility model optimize product structure, because electrode is arranged at middle part, terminal is the neck being clamped on filament bar, thus filament bar two ends of the present utility model are made also to be luminous, thus in use especially connect use when, end does not have dark space shadow, thus can be combined into the filament bar of a very long one; In addition, adopt flip-chip that gold thread can be prevented to be bent disconnected phenomenon and produce, cost low (need not gold thread be beaten), good heat dissipation.

Detailed description of the invention

Below preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.

See accompanying drawing 1 with shown in accompanying drawing 2, a kind of no dark space, terminal card neck two ends light emitting LED lamp strand, comprise the LED strand unit 10 of one or more interconnection, each LED strand unit 10 comprises transparent substrates 1, multiple LED chip 2 and connection line 3 prepared by transparent substrates 1, the both side surface of transparent substrates 1 is coated with fluorescence silica gel layer 6, transparent substrates 1 is prepared from by ceramic material, LED chip 2 is electrically connected by connection line 3 and two ends are prepared respectively and had positive and negative electrode 4, fluorescence silica gel layer 6 to be covered in LED chip 2 and to be exposed by positive and negative electrode 4, positive and negative electrode 4 be positioned at LED chip 2 side and away from the both ends of transparent substrates 1, positive and negative support terminals 5 supports LED strand unit 10 and correspondence is pressed on positive and negative electrode 4.

LED chip 2 adopts flip-chip, because this product uses upside-down mounting mode, avoids bonding wire bank too high, and technique is simple, and man-hour reduces; Upside-down mounting product is comparatively large due to current-diffusion layer area, when electric current increases, can adopt the undersized conceptual design product of big current; Adopt printed wire mode, without gold thread welding, early investment is less, produces in enormous quantities faster.

Accompanying drawing 3 is according to no dark space, terminal card neck two ends of the present utility model light emitting LED lamp strand connected mode one, in figure, multiple LED strand unit 10 is interconnected successively from beginning to end, owing to not having the shadow region at both ends, thus can connect is a luminous entirety.
