Abstract
The utility model discloses a COB light source and an LED lamp. The COB light source comprises a substrate and a plurality of LED wafers packaged on the substrate. Bonding pads are arranged on the substrate, serve as the positive electrode and the negative electrode of the COB light source and are respectively provided with a through hole allowing an electric conduction connecting pin to penetrate through. The LED lamp comprises a drive circuit board, the electric conduction connecting pins and the COB light source. One end of each electric conduction connecting pin is welded and fixed to the drive circuit board. The other end of each electric conduction connecting pin is inserted into the through hole of the corresponding bonding pad of the COB light source and connected with the bonding pad through in a tin soldering mode. The through holes are formed in the bonding pads of the COB light source, the COB light source is connected with the drive circuit board through the electric conduction connecting pins, and in other words, in the circuit connection process, a user only needs to directly insert the electric conduction connecting pins into the through holes of the bonding pads and complete welding through an automatic tin soldering machine; compared with the prior art, automated production can be more easily achieved, and production efficiency is improved.
Description
Technical field
The utility model relates to LED lighting technical field, particularly good COB light source and the LED lamp of a kind of circuit structure.
Background technology
LED due to have energy-saving and environmental protection, can be light-operated, the lot of advantages such as solidification, long-life, be widely used in the every field such as public illumination, office and room lighting in city.The disappearance gradually of Chinese population bonus, human cost rises year by year, promotes LED light fixture manufacture production efficiency irresistible.
Existing COB light source design scheme is generally: fixed wafer on substrate, by gold thread, realize the electrical connection between each wafer, and coating is mixed with the silica gel of fluorescent material, the both positive and negative polarity pad of COB is on the surface of COB, by wire bonds, be implemented in the electrical connection of power supply, advantage is that technique is simple to operation, and shortcoming production efficiency is low, need artificial welding, cannot realize automated job.
Utility model content
The utility model is for above-mentioned the deficiencies in the prior art, first the COB light source that a kind of cost is lower, facilitate circuit to connect is provided, moreover, a kind of LED lamp is provided again, this LED lamp directly carries out circuit connection by conduction connecting needle by drive circuit board and COB light source, and the pad that the connecting needle that is about to conduct electricity directly inserts COB light source connects by soldering again.
The technical solution of the utility model is achieved in that
A COB light source, comprises substrate and is encapsulated in the plurality of LEDs wafer on substrate, is provided with pad on substrate, and described pad is the positive and negative electrode of COB light source and the through hole that pad wears with confession conduction connecting needle.
A kind of LED lamp, this LED lamp comprises drive circuit board, conduction connecting needle and COB light source as claimed in claim 1, one end and the drive circuit board of conduction connecting needle are welded and fixed, and the other end of conduction connecting needle inserts the through hole of COB light source pad and is connected with pad soldering.
As preferably, described conduction connecting needle is L shaped.
As preferably, described conduction connecting needle also includes stop collar, is provided with two jacks on stop collar, and two pins of conduction connecting needle are located in jack respectively.Thus, not only can conveniently fix two pins, also can make to keep fixing spacing between two pins, avoid contact to cause short circuit.
The utility model is provided with through hole on the pad of COB light source, COB light source is connected with drive circuit board by conduction connecting needle, while being circuit connection, conduction connecting needle is directly inserted to the through hole of pad, by automatic tin welding machine, complete welding again, compared to prior art, more easily realize automated production, improving production efficiency.
