The combination of meaning.
The generally external 260V voltages of bulb lamp in the prior art drive, and four filaments, every lamp are connected in bulb lamp
The Shunt Voltage of filament voltage is 67V, and existing chip voltage is generally less than 3V, therefore every filament needs the series connection of 25 chips,
LED chip quantity is more.
Fig. 1 is the structural schematic diagram of LED filament in the prior art, and each LED chip 421 is connected in series with, LED chip 421 it
Between there are certain intervals, LED chip 421 to be arranged in a linear on substrate 41, and be connected in series with by bonding line 43,41 liang of substrate
End is also respectively provided with a pin 45, is connected by bonding line between the pin 45 and LED chip 421.
Fig. 2 is the filamentray structure schematic diagram of the utility model one embodiment, 422 conducting voltage of LED chip of the filament 4
For 6V, because the voltage of single filament is 67V, therefore every filament only needs to use 13 LED chips 422, LED core in the present embodiment
Piece 422 is arranged in a linear on substrate 41, and substrate 41 can be such as ceramics, sapphire, organic polymer insulating substrate, also may be used
It is in certain intervals to be such as aluminium, copper technology substrate, between LED chip 422, is connected and connected by bonding line 43 between chip 422
It connects, the outer surface of LED chip 422 is coated with packing colloid 44, and 41 both ends of substrate are respectively connected with a pin 45, and pin 45 can be with
Other filaments or electric elements connection, are connected between LED chip 422 and pin 45 by bonding line 43, which is
Fluorescent glue, the fluorescent glue can be the mixtures of silica gel and fluorescent powder grain.
Because of the reduction of 43 quantity of quantity and bonding line of LED chip 422, the life of filament and bulb lamp is on the one hand reduced
Cost is produced, on the other hand, the dispensing of packing colloid and LED chip pickup number also further reduce so that the production time reduces,
Improve production efficiency.
Fig. 3 is the structural schematic diagram of another embodiment of filament of the utility model, and the filament 4 in the present embodiment includes 3 kinds
LED chip, respectively 3VLED chips 421,6VLED chips 422 and 9VLED chips 423,3VLED chips 421 are 3,6VLED
Chip 422 is 4, and 9VLED423 chips 423 are 4, and 3VLED chips 421 are placed in 41 center of substrate, 421 both sides of 3VLED chips
Two 6VLED chips 422 are arranged respectively, and 9VLED chips 423 are placed in 41 outermost end of substrate, and often end places two, because of 9VLED cores
The quantity of heat production highest of piece 423,6VLED chips 422 take second place, and 421 calorific value of 3VLED chips is minimum, can using such arrangement mode
Effectively to disperse the temperature at 41 middle part of substrate, avoids filament from influencing the normal work of bulb lamp because generation heat is excessive, carry
The high reliability of product.
With reference to Fig. 4, bulb lamp includes a lamp cap 1, and 1 outer surface of lamp cap is in a helical form, can be screwed in and 1 phase of lamp cap
In the lamp holder matched, for the extraneous power supply of bulb lamp normal work access, there are one wicks 2 for 1 top connection of lamp cap, and 2 lower end of wick can
It is inserted into lamp cap 1, wick 2 is a slim-lined construction, and the upper end is placed in lampshade 3, and transparent material can be used in lampshade 3, works as bulb lamp
Using embodiment as shown in Figure 2 or Figure 3 filament when, then bulb lamp normal work need four filaments, four filaments
Two filaments first connect, then parallel connection respectively is attached between filament, the filament connected is fixedly connected on by conducting wire 5
5 both ends of conducting wire on 2 top of wick, extraction are separately connected firewire and zero curve in lamp cap 1, and then realize that shining for filament is shinny.
With reference to Fig. 5, the 3VLED chips 421 that filament in the prior art as shown in Figure 1 uses are changed to 6VLED chips
When 422, in the case that LED chip quantity is constant in every filament, the filament in the present embodiment only need to be i.e. reachable using two
The 260V voltages needed to bulb lamp normal work, therefore the filament cost in bulb lamp is reduced to the basis of original half
On, the production efficiency of whole lamp is improved, which is connected by conducting wire 5, and 5 both ends of conducting wire equally connect in lamp cap 1
Firewire and zero curve, the bulb lamp of other structures and embodiment as shown in Figure 4 in bulb lamp can be consistent.
