Description
Affiliated technical field
The utility model relates to the flexibility luminous lamp strip of a kind of lighting device, particularly a kind of improvement.
Background technology
More and more ripe along with the LED technology, and have the advantage of luminosity height, long service life, so the LED application product is widely used as advertisement or as decorating, so the bar shaped ornament lamp is favored by very in market.
Also have inventor Ben Fan to invent a kind of Chinese patent application number to be: 200520062690.X, and U.S. Patent number is: US 6,914,194 B2, name is called " a kind of LED cord lamp that improves structure " this invention and has disclosed a kind of on the flexible cord inner core that is coated with the multiply copper stranded conductor more than 2 or 2, offer a cannelure that is parallel to the multiply copper stranded conductor, connect by electric wire between the single circuit board, the adopting surface mounted LED that is provided with on single circuit board and the circuit board embeds cross section and is provided with one less than rectangular recess in the cannelure of this cannelure for the convex shape bottom surface, and the flexible cord internal core wire coats flexible cord crust layer of transparent or translucent outward again.
Aforementioned inventor Ben Fan has also invented a kind of Chinese patent application: 200520063571.6 and U.S. Patent number be: US 7,034,230 B2, the technology that name is called " cord lamp in parallel in a kind of " this invention announcement almost is the same with above-mentioned patent in configuration aspects, different is that a plurality of LED enter and are electrically connected with the copper stranded conductor that conducts electricity by the inwall of electric wire series connection from pit in this invention, this invention has increased multiloop structure at the patent content of U. S. application in addition, but still there is following problem in above several inventions:
1, owing to welds by being connected electric wire between LED and the LED, can not weld automatically by mechanization, as use wave-soldering unit, what therefore making need be a large amount of is artificial, when the length of every unit hour, and have loaded down with trivial details, the consuming time defect of high cost of operation all LED need be connected on the copper stranded conductor time.
2, because inner layer fixed is shape in the groove; therefore the LED that is embedded in the groove must have the simultaneously exposed protective layer that do not have; so C.O.B. formula LED damages easily through the machine extrusion time; and because product needs in manufacturing process and will be embedded in LED in the groove by the machine of temperature up to 150 ℃, therefore when LED easier damage of LED when protecting without any coating.
3, because LED must be greater than distance predetermined between LED and the LED with the wire length that is connected between the LED, therefore this connection electric wire is filled in and is circuitous state in the recessed cannelure, therefore there is inaesthetic defective, and the inner layer fixed groove that should invent is very little, only limit to be connected in series by single electric wire between LED and the LED, therefore can not realize various glow color variation effects, if realize the words that multiloop is provided with, so since between LED and the LED to be connected electric wire too many, easy wrong position during making, knotting is not attractive in appearance easily, and production process is loaded down with trivial details.
4, owing to be connected electric wire for flexible between LED and the LED, so LED can not get fixing in the longitudinal direction position, LED can be pinched together in the bending process for product, thereby influence illumination effect.
5, be that aforementioned inventor has invented a kind of Chinese patent application and number is: 201010176873.X equally, name be called " a kind of ultrathin flexible lamp band; though reduced the thickness of product; because LED connect by lead; be arranged on then in the transverse holes in the heart yearn, the tow sides of LED all do not have supporter, only rely on the frictional resistance between horizontal hole wall and the LED side to support; in manufacturing process, have just disunity of LED position, thereby cause product not attractive in appearance; In addition the time by the extruder moulding, if LED exceeds the heart yearn surface, block mould easily, cause damage of product, when simultaneously heart yearn is by the extruder moulding since in the extrusion head all directions pressure differ to, therefore easily LED is squeezed out transverse holes, cause LED, cause product bad at horizontal direction displacement and LED and poor wire connection.
Have the utility model people to invent the patent No. in addition to be; 200720051428.4, name is called: a kind of patent of flexibility luminous lamp strip, this invention have disclosed and have a kind ofly comprised by flexible barcode fixed body, some unit flexible PCB plate, are arranged on LED on the flexible PCB plate, are coated on the fixed bed of flexible barcode fixed body periphery.Because flexible PCB plate and LED all are arranged in the strip fixed body longitudinal hole, therefore increased the thickness after the formed product, because fixed body and fixed bed are transparent plastic material, so can see electronic components such as inner pcb board and resistance from the product appearance, it is attractive in appearance to influence product in addition.
Therefore need that a kind of product fraction defective is low, production process is simple, attractive in appearance, product thickness low and cheaply technology substitute existing technical pattern.
