The utility model has the following advantages that since the folding assembly is adopted, the bulb can be simpler to assemble, has smaller structure, can adopts the glass housing of an ordinary filament lamp and a reflector lamp, is time-saving and material-saving, and can reduce the cost of the LED bulb.
Description
Technical field
The utility model relates to a kind of electric source lighting, specifically is to have released the LED bulb in the market.
Background technology
The LED bulb of having released in the market, be that life-span of generally acknowledging is long, the electric light source of power consumptive province, 5 watts of electric energy of LED bulb, can substitute 60 watts of incandescent lamps and 15 watts of power saving fluorescent lamps, and service life be 25 times of incandescent lamp, be 2000 hours demarcation service life of incandescent lamp, it is 50,000 hours that the LED bulb is demarcated service life.Low power LED lamp is saved about 1/3 electric weight than low power electronic energy-saving lamp, the LED lamp of a 13w high brightness is equivalent to the brightness of the common energy-saving lamp of 40w, fluorescent lamp electricity-saving lamp service life, generally about 1 year, can reach about 10 years the service life of LED fluorescent lamp.But present LED lamp, price is higher, thereby promotes slowly.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of manufacturing structure and assembly structure is simpler, cost is lower with emitting led bulb as light source.For this reason, the utility model is by the following technical solutions: it comprises glass bulb, lamp holder, and described bulb is provided with emitting led circuit board, and described emitting led and emitting led circuit board is electrically connected, collapsible and the expansion of described emitting led circuit board, the width after it is folding is less than the mouth diameters of glass bulb.Owing to adopt the technical solution of the utility model, the utlity model has following advantage: adopt collapsible assembling, assemble easyly, can make bulb structure littler and can adopt the glass bulb of ordinary incandescent lamp, reflection-type bulb, the material-saving that saves time makes LED bulb cost reduce.
Description of drawings
Fig. 1 is the cutaway view of a kind of embodiment provided by the utility model.
Fig. 2 is the vertical view of the emitting led connecting plate among Fig. 1.
Fig. 3 is the cutaway view of another kind of embodiment provided by the utility model.
The specific embodiment
With reference to attached Fig. 1 and 2.The utility model comprises glass bulb 1, lamp holder 2, and described bulb is provided with emitting led circuit board 6, and described emitting led 3 are electrically connected with emitting led circuit board, and described emitting led circuit board is collapsible and launch, and the width after it is folding is less than the diameter of the oral area 10 of glass bulb.
Described emitting led circuit board 6 is the two-piece type foldable structure, and the lead-in wire 41,42 that is electrically connected of described emitting led circuit board is drawn from described two different sheets respectively.In general, the two-piece type foldable structure has been enough to satisfy fills in glass bulb with emitting led circuit board, and if desired, emitting led circuit board also can adopt the more foldable structure of multi-disc.
Described bulb is provided with emitting led Electronic Control plate 5, play effects such as voltage stabilizing, light emitting control, power supply access, described Electronic Control plate 5 is fixed on glass bulb oral area 10 and is electrically connected with lamp holder 2, and the lead-in wire 41,42 that is electrically connected of described emitting led connecting plate is connected with described Electronic Control plate 5.
The installment state of described emitting led circuit board in being in glass bulb 1 is deployed condition, and its periphery rests on the glass bulb inwall and with glass bulb glue and bonds.Emitting led circuit board fixing in glass bulb, also can utilize with emitting led circuit board on the part that links to each other emitting led circuit board is fixed in the glass bulb inner chamber, described part can be electric wire or other Shape Parts on the emitting led circuit board.
Present embodiment adopts the two-piece type foldable structure, and described emitting led circuit board is made of two adjacent side by side circuit boards 62,63, has the gap between the adjacent circuit plate and fills bonding by flexible material 61.Emitting led 3 are electrically connected with circuit board.Circuit board 62,63 has constituted " sheet " in described two, and 62,63 of circuit boards can adopt common lead 64 to be electrically connected.Described flexible material 61 can adopt silica gel material to make, and described circuit board 62,63 is an aluminum-base printing circuit board.Like this, not only simple in structure, cost is low, and the elasticity of flexible material 61 is in conjunction with gapped adjacent side by side with circuit board 62,63, not only guaranteed folding but also guarantee expansion process smoothly and the bulk strength after launching.As mentioned above, if desired, the circuit board in the described emitting led circuit board also can be the multi-disc more than 2, and they are adjacent side by side successively, has the gap between the adjacent circuit plate and fills bonding by flexible material.
In the utility model, glass bulb 1 can adopt the envelope shape of incandescent lamp bulb or reflection-type bulb, they are less near the inner chamber at lamp holder 2 places, emitting led circuit board folded after, oral area 10 by glass bulb, emitting led connecting plate launches to rest on the glass bulb inwall after entering glass bulb 1 inner chamber place, the operation of its expansion process with and and the operation of the bonding of glass bulb inwall or its fixing operation at the glass bulb inner chamber can utilize instrument, also can utilize the described lead-in wire 41,42 that is electrically connected.
Should be pointed out that for those of ordinary skill in the art, under the prerequisite that does not break away from the utility model principle, can also change the utility model glass bulb, emitting led circuit board, Electronic Control plate.Adopt different shape as glass bulb, in the glass bulb or film outward, evaporation of aluminum in the glass bulb is used stained glass, or the like; Emitting led circuit board doubling or severally sell off for a short time, the Electronic Control plate is with all kinds etc.These also should belong to protection domain of the present utility model.
