Abstract

An LED double-bead string light of a flexible PCB is composed of straw-hat-shaped LEDs, secondary plastic packaging bases of the straw-hat-shaped LEDs, the flexible PCB, a U-shaped half casing pipe of the flexible PCB, a current limiting resistor, a sealing compound and a lead, wherein the current limiting resistor is welded to the flexible PCB and connected to an LED circuit in series, the sealing compound is poured into the U-shaped half casing pipe, and the lead is led out of the flexible PCB. The straw-hat-shaped LEDs secondarily packaged in a plastic mode are arranged in pairs, oppositely combined through the cooperation of dovetails and dovetail grooves formed in the back sides of the two straw-hat-shaped LED secondary plastic packaging bases, connected to the flexible PCB, evenly distributed and transversely installed through the LED lead led out of the bottoms of the two straw-hat-shaped LED secondary plastic packaging bases. Due to the fact that one pair of oppositely arranged straw-hat-shaped LEDs serves as a light source for each lighting unit, both-way beams are emitted, the illumination angle is large, and the actual effect vision full angle effect can be achieved to the greatest extent. Due to the fact that illumination of the LEDs cannot be weakened due to the packaging influence, compared with an LED string light of an existing flexible PCB, the LED double-bead string light has the advantage of being high in brightness.

Description

The two pearl cluster of lamps, ornamental of flexible PCB plate LED

Technical field

The utility model relates to a kind of nighttime landscape to be made and the ornamental cluster of lamps, ornamental of indoor and outdoor, particularly a kind of two pearl cluster of lamps, ornamental of LED that adopt flexible PCB plate.

Background technology

A cluster of lamps, ornamental is that nighttime landscape is made and the ornamental important equipment of indoor and outdoor, nowadays, along with scientific and technological progress, due to energy-conservation, life-span is long, brightness is high, stable performance, pollution-free simple with use, with LED make a cluster of lamps, ornamental just progressively replace traditional, with a cluster of lamps, ornamental for the brewed work of small filament lamp, and a current existing LED cluster of lamps, ornamental, again especially to use SMD LED, flexible PCB plate, be welded on flexible PCB plate and to be serially connected in the flexible PCB plate LED cluster of lamps, ornamental performance that current-limiting resistance in LED circuit and transparent envelope make the most outstanding, but this LED cluster of lamps, ornamental is also completing after assembling and will realize encapsulation by inject transparent silica gel in its transparent envelope, thereby the luminous big envelope that not only will see through of LED, could propagate out but also will see through the silica gel being full of between SMD LED and big envelope, brightness is very influenced, in addition, this LED cluster of lamps, ornamental luminous or unidirectional, lighting angle is little, can not reach the effect of actual effect vision full angle at all.

Summary of the invention

Technical problem to be solved in the utility model is that to overcome the brightness of an above-mentioned existing LED cluster of lamps, ornamental very influenced and can not reach the deficiency of actual effect vision full angle effect at all, and the two pearl cluster of lamps, ornamental of a kind of LED that adopts flexible PCB plate, the i.e. two pearl cluster of lamps, ornamental of flexible PCB plate LED are provided.

The technical scheme in the invention for solving the technical problem is: a kind of two pearl cluster of lamps, ornamental of LED that adopt flexible PCB plate, be the two pearl cluster of lamps, ornamental of flexible PCB plate LED, it is by straw hat type LED and secondary plastic packaging pedestal thereof, flexible PCB plate and U-shaped half-covering tube thereof, be welded on flexible PCB plate and be serially connected in the current-limiting resistance in LED circuit, the sealing of pouring in U-shaped half-covering tube and the lead-in wire of being drawn by flexible PCB plate form, described two of the straw hat type LED through secondary plastic packaging are a pair of, the opposing combination that matches of the dovetail arranging respectively by bis-plastic packaging pedestal rear sides of two straw hat type LED and dovetail groove, the LED lead-in wire of being drawn by bis-plastic packaging base bottom of two straw hat type LED is again connected on flexible PCB plate and is uniformly distributed, laterally install.

The two pearl cluster of lamps, ornamental of above-mentioned flexible PCB plate LED, can draw respectively lead-in wire by the two ends of flexible PCB plate.

The two pearl cluster of lamps, ornamental of this flexible PCB plate LED provided by the utility model, because each luminescence unit is all to make light source with the straw hat type LED of a pair of opposing setting, launch two-way light beam, thereby lighting angle is large, can farthest goes to realize the effect of actual effect vision full angle; Because the luminous impact not encapsulated of LED slackens, thereby compared with an existing flexible PCB plate LED cluster of lamps, ornamental, also have advantages of that brightness is high.
