Specific embodiment
Referring to Fig.1, a kind of metal wire built-in filament of the invention, including LED chip 1, substrate 2 and fluorescent glue 3,
The middle setting of LED chip 1 on a substrate 2, is electrically connected, substrate 2, which can transfer electrical energy on LED chip 1, makes LED core with substrate 2
Piece 1 shines, and fluorescent glue 3 is coated on outside LED chip 1 and substrate 2, and fluorescent glue 3 is by all LED chips 1 and part
Substrate 2 envelope, since substrate 2 needs to transmit electric energy, so the positive and negative anodes of substrate 2 are not enveloped by fluorescent glue 3, but
It reaches except fluorescent glue 3, for being attached with driving power.
And a heat-conducting metal silk 4 is additionally provided with inside fluorescent glue 3, one end of heat-conducting metal silk 4 is arranged in fluorescent glue 3
Interior and close substrate 2, the other end reaches outside fluorescent glue 3, and heat-conducting metal silk 4 is not contacted with substrate 2 and LED lamp bead
It arrives, in order to avoid influencing the temperature on heat-conducting metal silk 4, the effect of heat-conducting metal silk 4 is to pass the temperature of filament, is passed through
It is connected with temperature controlling device, realizes the monitoring to filament own temperature, prevents filament from generating more heat due to illuminating for a long time
Amount burns out LED chip 1 or other devices.
Specifically, heat-conducting metal silk 4 of the invention needs good heating conduction, so can use copper in design
Silk or aluminium wire are as heat-conducting metal silk 4.
Specifically, substrate 2 is sapphire substrate.
Specifically, fluorescent glue 3 be yellow fluorescent powder, fluorescent glue 3 by dispensing mode be coated on substrate 2, LED chip 1 with
And heat-conducting metal silk 4 is arranged inside fluorescent glue 3 simultaneously when making filament for the periphery of heat-conducting metal silk 4, it is then thermally conductive
4 one end of wire extends out to outside fluorescent glue 3, and for connecting with temperature controlling device, LED chip 1 is purple light chip or blue light core
Piece, the light issued can excite yellow fluorescent powder that entire filament is allowed to issue white light.
Referring to Fig. 2-Fig. 3, a kind of filament lamp of the invention, including built-in filament, the temperature sensor of heat-conducting metal silk 4
20, filament drive 30 and controller 40, filament drive 30 provide electric energy for filament, and temperature sensor 20 acquires heat-conducting metal silk
4 temperature, and collected temperature information is transferred to controller 40, controller 40 judges whether temperature mistake according to temperature information
Height, if judging, filament internal temperature is excessively high, controls filament drive 30 and reduces electric energy supply, reduces the brightness of filament, so as to
To reduce the heat of filament generation, prevent heat from excessively burning out other components.
It specifically, further include lamp cap 50 and lamp body 60, lamp cap 50 and lamp body 60 connect, and filament is arranged in lamp body 60,
