Description
Technical field
The utility model relates to a kind of LED elements, more particularly to a kind of LED from strip resistance.
Background technique
It is nonlinear electronic component since LED is C-V characteristic, after LED is loaded into voltage rating, electric current (or LED
Resistance) meeting great change with voltage or being slightly variable for temperature, there is the risk for burning LEDPN knot.To dissolve above-mentioned risk, existing LED
Power supply generally uses the precise and stable control electric current of constant-current source, but this control method higher cost, is not suitable for being applied to LED light string
Deng on the product for pursuing low cost.Existing LED light string generally prevents electric current great change from burning LED by the way of series resistance, but
This method needs the extra soldered resistance in lamp string, increases the complexity of cost and manufacturing process.
Summary of the invention
For overcome the deficiencies in the prior art, the utility model provides that a kind of structure is simple, simple process from strip resistance
LED.
The utility model solves technological means used by its technical problem: a kind of LED from strip resistance, including mutual
The first lamp base and the second lamp base of isolation, the chip erecting bed with the first lamp base one, the chip being welded on chip erecting bed,
The packing colloid of the chip and portion support is encapsulated, first lamp base, the second lamp base and chip erecting bed are by heat conductive insulating
System is made, and the chip erecting bed and lamp base surface are coated with predetermined resistance value coating.
The beneficial effects of the utility model are: due to first lamp base, the second lamp base and chip erecting bed of the utility model
It is made by thermal conductive insulator, the chip erecting bed and lamp base surface are coated with predetermined resistance value coating；So that LED itself is certainly
Strip resistance, there is no need to series resistance again, substantially reduced when manufacturing lamp string using the LED of the utility model LED light strip at
The complexity of this and manufacturing process.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of adopting surface mounted LED；
Fig. 2 is the structural schematic diagram of direct insertion LED.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.
Referring to Fig.1, a kind of adopting surface mounted LED encapsulates 2 He of chip including bracket 1 and the chip 2 being welded on bracket 1
The packing colloid 4 of portion support.The bracket 1 includes mutually isolated the first lamp base 11 and the second lamp base 12, with the first lamp base
The chip erecting bed 13 of 11 one, wraps up the chip erecting bed 13 and part the first lamp base 11, the insulation of the second lamp base 12 are fixed
Part 3.The cupulate bowl 31 that longitudinal section is inverted trapezoidal is provided with above fixing piece 3, the chip erecting bed 13 is placed in cupulate bowl 31.For just
In being provided with recess portion 131 in chip 2, the chip erecting bed 13, the chip 2 is fixed in the recess portion 131, core
Piece 2 is electrically connected with first lamp base 11, the second lamp base 12 respectively by bonding wire 5.Epoxy resin and glimmering is packaged in cupulate bowl 31
The packing colloid 4 of light powder mixture composition.
The manufacturing method of the utility model first is that, first by first lamp base 11, the second lamp base 12 and chip install
Platform 13 is using the production of the thermal conductive insulators such as heat-conducting plastic or thermal conductive ceramic, then in first lamp base 11, the second lamp base 12 and welds
The surface of chip erecting bed 13 plates the coating that nichrome or carbon film etc. have predetermined resistance value using high-temperature vacuum coating technology,
The resistance value can be adjusted control coating film thickness or by way of coating surface groove.Applied to the single led of LED light string
The resistance value of bracket is preferably controlled in 50 to 100 ohm, and best resistance value is 68 ohm.
The manufacture of the utility model second is that, directly adopt with predetermined resistance value conductive material manufacture, the material
It can be nichrome or carbon film, or adulterate non-conducting material in the common conductor materials such as copper or aluminium, resistance value passes through control
The ratio of non-conducting material is adjusted, and Standard resistance range is identical as one of mode.
With reference to Fig. 2, a kind of direct insertion LED, including bracket 1, the chip 2 being welded on bracket 1 and package chip 2 and part
The packing colloid 4 of bracket 1.The bracket 1 includes the first lamp base 11 and the second lamp base 12 being electrically isolated from each other, with the first lamp base
The chip erecting bed 13 of 11 one.To be easily installed chip 2, recess portion 131, the chip are provided on the chip erecting bed 13
2 are fixed in the recess portion 131, and chip 2 is electrically connected with the first lamp base 11 and the second lamp base 12 respectively by bonding wire 5.The envelope
Fill part the first lamp base 11 and the second lamp base 12 that colloid 4 wraps up chip erecting bed 13 and neighbouring erecting bed 13.The bracket
Manufacture is identical as a kind of adopting surface mounted LED of upper embodiment.
The utility model uses simple method, so that LED itself is made from strip resistance using the LED of the utility model
There is no need to series resistances again when making lamp string, substantially reduce the cost of LED light strip and the complexity of manufacturing process.
