Abstract
The present invention provides a kind of New LED filament lamp.The stem (20) of this New LED filament lamp is special, as long as not influencing the burn-back of stem (20) and blister (60), the diameter of the cylindrical tube (21) of stem 20 is as large as possible.Sealed-off flame can enter the deep inside of cylindrical tube (21), the sealed-off point (25) of air exhaust rod (26) is located at the top of cylindrical tube (21) close to gas vent (24), and driver (or controller) (40) is just placed in the space that cylindrical tube (21) inner cavity and lamp cap (10) inner cavity are formed.
Description
Technical field
The present invention relates to lighting engineering, more particularly to the LED filament lamp for using LED filament to design and make.
Background technology
LED filament shines for 360 ° around its axis, and light efficiency is high, and the requirement to heat dissipation is relatively low, can be directly encapsulated into general
In logical glass bulb, referred to as LED filament lamp.For currently a popular various LED filament lamps, the light bulb after exhaust need to be from row
Sealed-off on gas platform, due to existing stem, cylinder pipe diameter is smaller, and sealed-off flame is difficult to enter the bottom of stem cylindrical tube,
General filament lamp, for the sealed-off point of air exhaust rod all in the outside of core column horn shape flange, remaining air exhaust rod stays in cylindrical tube
Centre, so that driver cannot be put into the cylindrical tube of stem.In addition the diameter of stem cylindrical tube is smaller, nearly all LED light
The driver of silk lamp is all mounted in lamp cap narrow space, and the power of LED filament lamp is caused to be restricted, LED filament lamp
Some other controller, such as adjustable CD-ROM driver etc., it is difficult to so develop in narrow space in lamp cap.
Invention content
This New LED filament lamp includes lamp cap, and the light bulb of lamp cap and sealing is to be glued, and the light bulb of sealing is by glass envelope
Shell-and-core column burn-back forms, and LED filament is welded on the seal wire of stem.
The stem of this New LED filament lamp is special, under the premise of not influencing with blister burn-back, stem cylindrical tube
Diameter it is as large as possible.After LED filament lamp bank gas need to the sealed-off from exhaust station, due to stem cylinder pipe diameter increase, sealed-off
Flame can enter stem cylinder bottom of the tube, and the sealed-off point of air exhaust rod is located at the bottom of stem cylindrical tube close to the attached of gas vent
Closely, the dedicated glue of the light bulb of sealing is glued with lamp cap.In this way, other controllers of LED driver or LED filament lamp, example
Such as dimming driver, can be placed in the space of stem cylinder tube cavity and lamp cap inner cavity composition.Driver or controller
Input terminal is connected with lamp cap, and the output end of driver or controller is connected by two seal wires on stem with LED.
Description of the drawings
Fig. 1 is a kind of schematic cross-sectional view of new LED filament wick column of the present invention.
Fig. 2 is a kind of new LED filament lamp schematic cross-sectional view of the present invention.
Specific implementation mode
In conjunction with above-mentioned description of the drawings specific embodiments of the present invention.
As shown in Figure 1, the stem 20 of this New LED filament lamp, stem main body are cylindrical tube 21, the lower part of cylindrical tube 21
It is horn-like flange 27, the burn-back of cylindrical tube top has supporting rod 23, and for fixing LED filament 50, the top of cylindrical tube 21 is used
Two seal wires 22 of clamp and air exhaust rod 26 are flattened after flame scorification, the top of air exhaust rod 26 is provided with gas vent 24, as long as not influencing
The diameter of the burn-back of stem 20 and blister 60, cylindrical tube 21 is as large as possible, and the horn-like flange 27 of the lower part of cylindrical tube 21 is most
It is possibly smaller.
As shown in Figure 2, special stem 20 needs to be vented with the sealed bulb after 60 burn-back of blister, the sealed bulb after exhaust
Should be with exhaust station vacuum system sealed-off, since the cylindrical tube 21 of stem 20 is relatively large in diameter, sealed-off flame can enter circle
The sealed-off point 25 of the deep inside of column tube 21, air exhaust rod 26 is located at the top of cylindrical tube 21 close to gas vent 24, sealed bulb use
Dedicated glue 30 is glued with lamp cap 10, and driver (or controller) 40 is just placed on 21 inner cavity of cylindrical tube and the lamp cap 10 of stem 20
In the space that inner cavity is formed, the input terminal of driver (or controller) 40 is connected with lamp cap 10, driver (or controller) 40
Output end be connected with LED filament 50 by two seal wires 22 on stem 20.
The above content is combine specific preferred embodiment to further description made by invention, and it cannot be said that originally
The specific implementation of invention is confined to these explanations.For those of ordinary skill in the art to which the present invention belongs, not
Under the premise of being detached from present inventive concept, a number of simple deductions or replacements can also be made, all shall be regarded as belonging to the guarantor of the present invention
Protect range.
