Flexible LED light-emitting moduleTechnical field
The present invention relates to a kind of flexible LED light-emitting module, particularly a kind of waterproof and dustproof, the LED light emitting module that packaging efficiency is high.
Background technology
Light emitting diode (Light Emitting Diode; LED) it is little to have a volume, the efficient height, advantages such as life-span length are because science and technology is constantly progressive, its photoelectric transformation efficiency also constantly promotes improvement, converts electric energy to more high efficiency, and relevant therewith low amount of heat divergence and little total position occupancy volume of luminous energy in limit of visible spectrum.LED-based above-mentioned advantage adopts led light source to replace conventional light source more and more on neon light, billboard.But, at first need drop into some more costs during fabrication, this is owing to must be assembled by a plurality of light emitting diodes that constitute an array format with the little event of luminous intensity that an incandescent lamp is compared each light emitting diode.
For realizing light emitting diode matrix, up to now, known multiple scheme.Described a kind of light-emitting diode (LED) module as US5404282, a plurality of light emitting diodes wherein have been installed between two parallel bus regularly.This structure is effective relatively on circuit engineering, but does not but have flexibility for the lamp box of packing into, because it can not be fit to crooked box-like shape easily.Therefore, the led module that adopts flexible wire to connect has appearred, but existing flexible LED module is to adopt to connect the connected mode of wire bonds on the LED wiring board, connects built on the sand, and water resistance is bad, and the heat that produces during owing to welding, damage easily LED, and when assembling need wire bonds in the circuit board after, again wiring board is put into housing, articulate, reduced production efficiency.
Summary of the invention
The objective of the invention is to: provide a kind of water resistance good, do not influence the LED quality, the flexible LED light-emitting module that packaging efficiency is high.
Technical scheme of the present invention is:
A kind of flexible LED light-emitting module, include housing, lead, wiring board is installed LED in the circuit board, it is characterized in that, lead passes enclosure interior, and wiring board is fixed on enclosure interior by metallic screw, and the power delivery contact on the wiring board is electrically connected with metallic screw, wire insulation body inside is stretched at the tip of metallic screw, contacts with metal core in the lead.
The technical scheme that can add is as follows on this basis:
Described flexible LED light-emitting module is characterized in that, is injected with epoxy resin in housing.
Described flexible LED light-emitting module is characterized in that, housing and lead are an overall structure.
The invention has the beneficial effects as follows: abandoned traditional electronic component assembling pattern, adopted screw to connect lead,, improved production efficiency of products greatly, also can not damage the quality of LED, also improved connection stability owing to need not welding; Adopt the overall structure of housing and lead, effectively raise its water resistance (reaching IP65), dustproof, anti-oxidation performance.
Description of drawings
Fig. 1 is an assembly drawing of the present invention.
Fig. 2 is a screw of the present invention, housing, lead, the partial enlarged view of wiring board coupling part.
Wherein, Reference numeral: 1 is housing, and 2 is lead, and 3 is the metal core, and 4 is wiring board, and 5 is LED, and 6 is screw, and 7 is the power delivery contact.
The specific embodiment
The present invention is further described below in conjunction with drawings and Examples.
Specific embodiments of the invention, as shown in Figure 1, a kind of flexible LED light-emitting module, includehousing 1 andlead 2 by the injection moulding of fire-retardant nylon disposal molding, the screw fixing port that arc is arranged in lower end,housing 1 both sides, LED5 is installed on the two-layer printedcircuit plate 4, it is characterized in that,lead 2 passeshousing 1 inside,wiring board 4 is fixed onhousing 1 inside bymetallic screw 6, and thepower delivery contact 7 on thewiring board 4 is electrically connected withmetallic screw 6, andlead 2 insulator inside are stretched at the tip ofmetallic screw 6, contactmetallic screw 6 with themetal core 3 in thelead 2,wiring board 4,housing 1, the annexation oflead 2 as shown in Figure 2.
On the basis of the foregoing description inhousing 1 injection moulding epoxy resin again, make this led module waterproof (performance reaches IP65), dustproof, anti-oxidation.In the quantity that can also adjust the LED5 on thewiring board 4 on the basis of present embodiment, can between the 2-5 root, adjust the radical oflead 2 according to the characteristic of product.
The present invention adoptsscrew 6 to link to each other withlead 2 with regard to printed circuit board (PCB), make modular structure simple, be suitable for the production line machinery processing, avoided technology and the bad infringement of Yin Wendu control numerous and diverse inwelding lead 2 processes to LED, reduced cost, improved quality, and because housing 1 andlead 2 injection moulding have together improved water resistance greatly.
