Description

A kind of LED bulb structure

Technical field

The utility model relates to field of illuminating lamps, relates in particular to a kind of structure of LED bulb.

Background technology

Along with the development of electric light source technology, human lighting system is also constantly progressive.Especially the proposition of light emitting diode (LED) technology, it is exactly a kind of typical semiconductor recombination luminescence light source.The principle of luminosity of light emitting diode (LED) is the compound light that sends of semi-conductive particle when utilizing electric current to flow through semiconductor chip.Because LED is a kind of illumination mode that electric energy can be converted into visible light, therefore have above-mentioned two kinds of traditional lighting systems incomparable advantage.It has that volume is little, consuming electric power is low, the advantage of environmental protection more, sturdy and durable, long service life.

Though can reach the service life of LED more than at least 2.5 ten thousand～50,000 hours, be much higher than other lightings (for example 8000 of electricity-saving lamp hours).Yet can damage the service life of the electronic component of the driving power plate of LED owing to influences such as damp condition, temperature conditions cause component ageing, the superelevation service life of the relative LED of driving power plate of LED, shorter relatively.The common employing global design of the LED of existing LED bulb and power panel is usually for no other reason than that the damage of the driving power plate of LED and cause the whole LED bulb to be scrapped.

In addition, because existing LED bulb adopts above-mentioned one design, so bulb structure all is to adopt rotation mode or gummed mode to constitute.Such structural design is when changing the bulb lampshade, and is very inconvenient.As adopting rotation mode when screwing the screw socket joint, forward or reverse all can cause LED lamp bulb cover structure loosening, and is very not convenient on safeguarding; As adopt the gummed mode to cause untidy and the pollution bulb because of factors such as glue expose, changing LED bulb lampshade if desired then needs the whole bulb structure that destroys, especially can't maintenance maintenance.

Moreover in the existing LED bulb structure, the LED substrate generally adopts lead to be connected with LED driving power substrate.On the one hand it needs scolding tin to connect when producing, because solder joint comes off and causes electrically connecting unreliable, it is that lead connects on the other hand, the exposed hidden danger that also causes electric short circuit easily of the end of a thread easily.

At last, the radiator of existing LED bulb structure generally adopts the die cast of one or aluminium extruded mould or finish cast die mode one-body molded, can cause the radiating fin thickness of entire heat dissipation body big, Heavy Weight, thus influence the weight of whole LED bulb.

The utility model content

Therefore, at the above-mentioned various deficiencies of existing LED bulb structure, the utility model proposes a kind of improved LED bulb structure.The whole employing of LED bulb structure of the present utility model fastens the socket joint type structure, and LED substrate and power supply board adopt the plug in construction of no lead, and radiator is a split-type structural.

The utility model adopts following technical scheme:

LED bulb structure of the present utility model comprises that successively the lampshade on the top that connects, the screw socket joint of middle bulb, the LED substrate between described bulb and lampshade and lower end form bulb structure.Wherein, described bulb is made of radiator, insulating sleeve and power supply board, and described radiator is socketed on outside the insulating sleeve, and described power supply board is arranged in the insulating sleeve, described LED substrate is embedded in a heat radiation pallet, and is plugged in the plug of described power supply board.

Further, described radiator comprises heat-dissipating cylinder and a plurality of radiating fin, and described heat-dissipating cylinder is a plurality of slots of distribution vertically, and described radiating fin inserts in this slot.

Further, described heat-dissipating cylinder lower end evenly distributes a plurality of socket decks is set, and the socket dop of respective numbers is set on the described insulating sleeve convex edge, and described radiator is socketed on outside the insulating sleeve.

Further again, the quantity of described socket deck and socket dop is 1 or a plurality of.Preferably each 3, can also be 4,6,8 or other numbers.

Further, vertically be provided with two slots in the described insulating sleeve, the dual-side of described power supply board inserts in this slot.

LED bulb structure of the present utility model adopts as above technical scheme, has following advantage:

1. the bulb overall structure adopts and fastens and the socket joint type structure, so need not rotation or gummed, safeguards and changes facility more.

2.LED substrate and power supply board adopt the plug in construction of no lead, do not need wire bonds, can not cause insecure problem and the exposed short circuit problem of lead of opening circuit of solder joint.

3. radiator is a split-type structural, processes not only conveniently, and overall weight is lighter, more economical with materials.

4. the LED substrate of LED bulb of the present utility model and power supply board are connected structures dividually, if because the damage of power panel and only need change this partial component can not cause the whole LED bulb to scrap problem.
