Description
Technical field
The utility model relates to a kind of technical field of structure aspects of LED bulb, particularly relate to a kind of have great heat radiation effect, easy to assembly fast, can increase the service life and LED bulb person that side face can send effects such as gentle light.
Background technology
General existing known LED bulb, announce shown in the M402387 patent as TaiWan, China, it mainly is located at a plurality of led chips on the circuit board of aluminium material, again this circuit board is combined on the heat-conducting plate of aluminium material, then this heat-conducting plate is assembled in an end of the radiating seat of aluminium material, side in opposite this radiating seat of this heat-conducting plate is combined with lampshade for this circuit board and these a plurality of led chips are covered with, being combined with adapter in the other end of this radiating seat can be for can being installed on the light bulb holder, and in this radiating seat, be provided with transformer for and this adapter and this circuit board electrically connect.So, when led chip is luminous the high temperature that produces just can conduct to the heat-conducting plate of aluminium material via the circuit board of aluminium material, relend the radiating seat that is conducted to aluminium material by the heat-conducting plate of aluminium material, by a plurality of radiator shutters on the radiating seat side face and radiating groove therebetween heat is spread in the ambient air to reach cooling-down effect then, simultaneously and utilize a plurality of louvres on the heat-conducting plate that the temperature of circuit board is directly shed to the through hole of this radiating seat inside, so that this hot gas can discharge by the ventilative conduit guiding of radiating seat and by ventilative short slot, with the effect of further raising radiating and cooling.
Yet this existing known LED bulb can produce following many shortcomings when actual fabrication and use:
1, since the heat that the led chip of existing known LED bulb produces when luminous need pass through this circuit board, this heat-conducting plate and this radiating seat just can be distributed to extraneous air in, and this circuit board, this heat-conducting plate and this radiating seat can form thermal resistance and the conduction efficiency of the heat of this led chip is significantly reduced, and then influence its radiating effect.And, this radiating seat only utilizes near a plurality of ventilative short slot on the end face of this adapter the hot gas of inside is discharged, the situation that the heat extraction poor effect not only can far be arranged because of the distance thermal source, especially those ventilative short slots can't form convection current with the cold air of outside, and therefore inner hot gas is difficult for discharging and having the situation of accumulating and takes place.So, very poor of its integral heat sink effect.
2, this existing known LED bulb needs earlier a plurality of led chips are combined on this circuit board, and then with this circuit board screw lock on this heat-conducting plate, and with this heat-conducting plate screw lock on this radiating seat, so its assembling bothers very much and inconvenience.Especially, if the fit-state between this circuit board and this heat-conducting plate and this heat-conducting plate and this radiating seat has very many spaces, its heat-conducting effect is significantly reduced, therefore can further increase the degree of difficulty of assembling and the time that spends especially.
3, the circuit board of this existing known LED bulb covers a plurality of louvres on the heat-conducting plate, so this circuit board and on a plurality of led chips can be covered in airtight space by this lampshade and this heat-conducting plate, the heat that produces when therefore these a plurality of led chips are luminous just can make the confined space of this lampshade inside be full of hot gas, and this hot gas can't be derived the outside, therefore in case the time be once can causing very large influence to this led chip for a long time, and then significantly shortened its service life.
4, owing to should be covered by in this lampshade and this heat-conducting plate by existing known LED bulb, wherein this lampshade is light-permeable, this heat-conducting plate is aluminium material and lighttight, so the light that these a plurality of led chips send just only can only project heat-conducting plate towards the direction of lampshade, this heat-conducting plate to peripheral part of this adapter then can not have and shines because light is subjected to stopping of this heat-conducting plate, therefore can be black dull state.
This shows that above-mentioned existing LED bulb obviously still has inconvenience and defective, and demands urgently further being improved in structure and use.Therefore how to found a kind of LED bulb of new structure, also becoming the current industry utmost point needs improved target.
