Technical field
The present invention relates to a kind of LED, more particularly to a kind of uniform LED that lights.
Background technology
LED of the prior art, including multiple LED luminescence components arranged successively, it is all provided with luminescence component The LED pasters of multiple length direction equidistant placements along light bar are equipped with, because the both ends of luminescence component need to lead with positive pole respectively Line and cathode conductor are attached, and therefore, are provided with the two-end-point of luminescence component and positive wire or cathode conductor progress The connecting portion of connection.When multigroup LED luminescence components are arranged successively, the LED of the least significant end of previous group LED luminescence components Be folded between the LED pasters of the front end of paster and later group LED luminescence components previous group LED luminescence components connecting portion and The connecting portion of later group LED luminescence components.When the spacing for the LED pasters equidistantly arranged in LED luminescence components is smaller, before making The spacing of the LED pasters of one group of LED luminescence component least significant end and the LED pasters of later group LED luminescence components front end is more than LED The spacing of LED pasters on luminescence component, so that the spacing of two LED pasters adjacent in LED is uneven, so as to lead Cause LED Integral luminous uneven.In addition, when manufacturing LED, the length of LED need to generally be determined Position, to carry out automatic detection to the length of LED or to carry out automatic code-spraying operation in the bottom of LED.Therefore generally Process gap can be set between two adjacent LED luminescence components again, to make detection means can be by the process gap pair Quantity-produced LED carries out automatic detection, positioning and carries out automatic code-spraying operation, due to the presence of process gap so that The LED pasters for the previous group LED luminescence component least significant ends arranged successively and the LED pasters of later group LED luminescence components front end Spacing will necessarily further increase so that the uniformity of two LED paster spacing adjacent in LED is worse, LED Band it is luminous also more uneven.
The content of the invention
A kind of present invention seek to address that above-mentioned mentioned technical problem, there is provided luminous LED that is uniform, being easy to the manufacturing Light bar.
The present invention is realized by following technical scheme：
A kind of LED of energy-conservation, including transparent casing and be coated in transparent casing positive wire, cathode conductor and Some groups of LED luminescence components parallel with one another, length direction of some groups of LED luminescence components along transparent casing are arranged successively Cloth, flexible PCB of the every group of LED luminescence component including regular length connect with some series connection being arranged on flexible PCB The LED chip units connect, current-limiting resistance are in series with the series circuit that some LED chip units for being connected in series are formed, each Include at least two LED pasters parallel with one another on LED chip units, LED pasters electrically connect with flexible PCB, flexible circuit Plate includes the body being attached with LED pasters and the end for being arranged at body and the reflex part for carrying out bending backward, reflex part The bottom of body is arranged at, is folded with some cylinders between reflex part and body, between some cylinders and cylinder and body, folding Cementation is carried out by heat conductive silica gel between the portion of returning, the bottom of reflex part is provided with mutually to be electrically connected with the circuit layer on flexible PCB The conductive contact connect, conductive contact are electrically connected with positive wire or cathode conductor by connecting wire, and connecting wire passes through The mode of welding is connected with conductive contact；
All LED pasters in the LED carry out single-row equidistant arrangement in transparent casing.
Further, the upper surface of the body is coated with reflective membrane.
Further, the transparent casing includes inner tube set and the outer tube sleeve being coated on outside inner tube set.
Further, it is provided with granular male and fomale(M＆F) on the inwall of said inner tube set.
Further, granular male and fomale(M＆F) is provided with the outer surface of the outer tube sleeve.
Further, the outer wrap of the connecting wire has gum cover.
Beneficial effect is：The present invention LED, by the both ends of body set reflex part, and by reflex part with Positive wire or cathode conductor are attached, and make the previous group LED luminescence components of some LED luminescence components arranged successively last The spacing of the LED pasters at end and the LED pasters of later group LED luminescence components front end can be adjusted arbitrarily, preferably be sent out according to LED The spacing of two adjacent LED pasters carries out relative set on optical assembly, to realize all LED pasters in LED transparent Equidistantly arranged in sleeve pipe.The group simultaneously as the LED pasters and later group LED of previous group LED luminescence component rearmost ends light The LED pasters of part front end are provided with spacing, and the usual spacing is necessarily to be manufactured more than 0, therefore to LED When, the length of LED is positioned using the gap, to carry out automatic detection or in LED to the length of LED The bottom of light bar carries out automatic code-spraying operation, is easy to implement the fully-automatic production of LED.
