Background technology
LED lamp band of the prior art, including multiple led luminescence components arranged successively, is all provided with luminescence component It is equipped with the led paster of multiple length direction equidistant placement along light bar, because the two ends of luminescence component need to lead with positive pole respectively Line and cathode conductor are attached, and therefore, be provided with and carry out with positive wire or cathode conductor on the two-end-point of luminescence component The connecting portion connecting.When multigroup led luminescence component is arranged successively, the led of the least significant end of previous group led luminescence component Be folded between paster and the led paster foremost of later group led luminescence component previous group led luminescence component connecting portion and The connecting portion of later group led luminescence component.When the spacing of the led paster of arrangement equidistant in led luminescence component is less, before making The led paster of one group of led luminescence component least significant end is more than led with the spacing of later group led luminescence component led paster foremost The spacing of the led paster on luminescence component, so that the spacing of adjacent two led pasters in LED lamp band is uneven, thus leading Cause LED lamp band Integral luminous uneven.Additionally, when manufacturing LED lamp band, it is fixed generally the length of LED lamp band need to be carried out Position, to carry out automatic detection or to carry out automatic code-spraying operation in the bottom of LED lamp band to the length of LED lamp band.Therefore usual Between two adjacent led luminescence components, process gap can be set again, to make detection means can pass through this process gap pair Quantity-produced LED lamp band carries out automatic detection, positions and carries out automatic code-spraying operation, due to process gap presence so that The led paster of previous group led luminescence component least significant end arranged successively and later group led luminescence component led paster foremost Spacing will necessarily increase further so that the uniformity of adjacent two led paster spacing in LED lamp band is worse, LED lamp Lighting of band is also more uneven.
Content of the invention
Present invention seek to address that above-mentioned mentioned technical problem, provide a kind of luminous led that is uniform, being easy to the manufacturing Light bar.
The present invention is to be realized by following technical scheme:
A kind of LED lamp band of energy-conservation, the positive wire including transparent casing and being coated in transparent casing, cathode conductor and some Organize led luminescence component parallel with one another, some groups of led luminescence components are arranged successively along the length direction of transparent casing, often Group led luminescence component all includes the flexible PCB of regular length and some being connected in series of being arranged on flexible PCB Led chip unit, the series circuit that some led chip units being connected in series are constituted is in series with current-limiting resistance, each led pastes At least two led pasters parallel with one another are included on blade unit, led paster is electrically connected with flexible PCB, flexible PCB bag Include the body being attached with led paster and be arranged at the end of body and carry out the reflex part of bending backward, reflex part is arranged In the bottom of body, between reflex part and body, it is folded with some cylinders, between some cylinders and cylinder and body, reflex part Between all cementation is carried out by heat conductive silica gel, the bottom of reflex part is provided with and is electrically connected with the circuit layer on flexible PCB Conductive contact, conductive contact is electrically connected by connecting wire with positive wire or cathode conductor, and connecting wire passes through welding Mode be connected with conductive contact；
All led pasters in described LED lamp band carry out single-row equidistant arrangement in transparent casing.
Further, the upper surface of described body is coated with reflective membrane.
Further, described transparent casing includes inner tube set and is coated on the outer tube sleeve outside inner tube set.
Further, the inwall of said inner tube set is provided with granular male and fomale(M＆F).
Further, the outer surface of described outer tube sleeve is provided with granular male and fomale(M＆F).
Further, the outer wrap of described connecting wire has gum cover.
Beneficial effect is: the LED lamp band of the present invention, by the two ends of body arrange reflex part, and by reflex part with Positive wire or cathode conductor are attached, and make the previous group led luminescence component of some led luminescence components arranged successively last The spacing of the led paster and later group led luminescence component at end led paster foremost can arbitrarily adjust, and is preferably sent out according to led On optical assembly, the spacing of two adjacent led pasters carries out relative set, to realize all led pasters in LED lamp band transparent Equidistantly arranged in sleeve pipe.The group simultaneously as the led paster of previous group led luminescence component rearmost end and later group led light Part led paster foremost is provided with spacing, and generally this spacing is necessarily more than 0, therefore LED lamp band is being manufactured When, can be utilized this gap the length of LED lamp band to be positioned, to carry out automatic detection or in led to the length of LED lamp band The bottom of light bar carries out automatic code-spraying operation, facilitates implementation the fully-automatic production of LED lamp band.
Brief description
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail:
