Description
Technical field
The invention belongs to LED bulb technical field, be specifically related to a kind of LED bulb of perfect heat-dissipating.
Background technology
In recent years, because the development of LED industry is rapid, LED lamp progressively replaces traditional lighting.New its illuminator of a product released is similar to incandescent lamp tungsten filament in the market, light efficiency is higher, lighting angle is close to incandescent lamp, but its production efficiency is low, yield rate is low, LED silk as light source in prior art forms by many usually, the heat produced in its luminescence process cannot distribute in time, greatly reduces the luminous efficiency of light source.Due to narrow space in the lamp holder of standard, driving power is arranged in this narrow space, and circuit welding and encapsulation all have very large difficulty, and high temperature during welding also very easily causes the damage of electrical equipment; In bulb use procedure, again because rear drive power supply is in this narrow space, poor heat radiation, Long-Time Service easily causes the generation of sealing-off phenomenon; Again on the one hand, in so narrow space, welding and encapsulation, can only carry out manual operations, the means of automatic and mechanical cannot be used to accomplish scale production.
Summary of the invention
For solving the problem of LED bulb poor heat radiation in prior art, the present invention proposes a kind of LED bulb, and this LED bulb, by setting up heat conduction ring and extension, has both solved the problem in welding space, also substantially increased radiating effect, extend the service life of lamp.
Technical scheme of the present invention is achieved in that
A kind of LED bulb, comprise lamp holder, light source board and cell-shell, the lateral surface of described light source board is provided with LED light source, also comprise extension, heat conduction ring, circuit board and driving power for subsequent use, described extension is between described lamp holder and described cell-shell, described light source board is disposed on the end face of extension around the central shaft of this lamp holder, bottom and the described extension of described heat conduction ring are thermally coupled, described circuit board is arranged on the end face of described extension and is positioned at the below of described heat conduction ring, described light source board is electrically connected with described circuit board through described heat conduction ring, described driving power for subsequent use to be arranged in described lamp holder and to be electrically connected with described circuit board.
Further, be also provided with heat-conducting glue between described light source board and described LED light source, described heat-conducting glue also part is connected with described heat conduction ring.
Further, described heat-conducting glue is silica gel, and its inside is provided with fluorescent material.
Further, the height of described extension is 3-6mm, and its periphery is provided with insulated ring.
Further, described extension is step-like or horn mouth.
Further, the quantity of described light source board is two, and two described light source boards are symmetricly set on the end face of described extension.
Beneficial effect of the present invention:
1, LED bulb of the present invention has set up heat conduction ring, can be delivered to above heat conduction ring by the heat that light source board produces in time, then be passed in lamp holder, then be distributed in air;
2, the present invention sets up extension at lamp holder end face, make the space enlargement in lamp holder, the setting of driving power for subsequent use becomes easy, and solves welding and encapsulate problem that is difficult, poor heat radiation, reduce and even stop the generation of sealing-off phenomenon, improve product service life;
3, the present invention is also provided with heat-conducting glue between light source board and LED light source, the heat of LED light source can be passed to above heat-conducting glue by this heat-conducting glue in time, is then passed on heat conduction ring, then is passed in lamp holder, then be distributed in air, substantially prolongs the service life of LED light source.
