Description

LED straw hat lamp suitable for surface mounting
Technical Field
The utility model relates to a LED technical field, concretely relates to LED careless cap lamp that is fit for paster.
Background
The LED straw hat light source device is widely used in the fields of decorative lamps, indication, advertisement display, etc. due to its characteristics of high luminous efficiency, low power consumption, no pollution, etc. With the increase of labor cost, people replace the original manual operation mode with automatic equipment, so that the demand that devices are more suitable for the production of the automatic equipment is needed.
As shown in fig. 1, a chip 6 is bonded on a die attach board 9, a first bonding wire 8 and a second bonding wire 4 connect a first electrode 7 of the chip and a second electrode 5 of the chip to the die attach board 9 by bonding, a closed circuit path is formed at the die attach board 3, and appropriate current is applied to a negative pin 1 and a positive pin 2 of the straight pin, so that the chip 6 emits light and generates heat at the same time, and the generated heat is conducted to the negative pin 1 and the positive pin 2 of the straight pin through the die attach board 9 and the die attach board 3 of a bracket, and then conducted to an external heat sink.
Disclosure of Invention
An object of the utility model is to prior art's defect and not enough, provide a reasonable in design's LED straw hat lamp that is fit for the paster, utilize automatic chip mounter production, improve production efficiency, save labour cost, solved current straw hat lamp and need artifically participate in the grafting installation with two long positive and negative directly and bring inefficiency, the drawback that labour cost is high.
In order to achieve the above purpose, the utility model adopts the following technical proposal: the chip comprises a bonding wire bottom plate, a second bonding wire, a chip second electrode, a chip first electrode, a first bonding wire and a die bonding bottom plate; the circuit also comprises a first patch bonding pad and a second patch bonding pad; a chip is fixed on the die bonding bottom plate, a first chip electrode and a second chip electrode are fixed on the chip, the first chip electrode is connected with the die bonding bottom plate through a first bonding wire, and the second chip electrode is connected with the bonding wire bottom plate through a second bonding wire; the first chip bonding pad is fixed at the outer end of the die bonding base plate, and the second chip bonding pad is fixed at the outer end of the bonding wire base plate.
After the structure is adopted, the beneficial effects of the utility model are that: the utility model provides a LED straw hat lamp that is fit for paster utilizes automatic chip mounter production, improves production efficiency, saves labour cost, has solved current straw hat lamp and has needed the manual work to insert the installation with two long positive and negative straight pins and bring inefficiency, drawback that labour cost is high.
Description of the drawings:
fig. 1 is a schematic structural diagram of the background art.
