The LED bulb-shaped lamp
Technical field
The utility model belongs to technical field of lighting fixtures, relates in particular to a kind of LED bulb-shaped lamp, can replace traditional lighting to use bulb.
Background technology
The LED bulb-shaped lamp of prior art; LED lamp plate assembly is installed on an end of radiator; And cover said lamp plate assembly and lampshade is installed at an end of this radiator, and lamp head shell is installed at the other end of this radiator, bright circuit for lamp is installed between radiator and lamp head shell.
For this kind bulb-shaped lamp; The heat that is produced from the LED element can cause that the whole temperature of LED bulb-shaped lamp rises; Thereby the light output that causes the LED bulb-shaped lamp descends and the lost of life; Rise so requirement can suppress the LED temperature, for this reason, adopt the method that forms radiator through excellent material of thermal diffusivity and moulding convex-concave surface etc.
Yet, in possessing the bulb-shaped lamp of lampshade, because LED is covered with by lampshade, so it is poor to exist the radiating efficiency of following problem: LED, even if the temperature of using metal radiator also can't suppress the LED bulb-shaped lamp fully rises.
In addition, the radiator portion of the LED lighting of prior art utilizes entity metal Vehicle Processing technology to process, and has the problem that manufacturing cost is too high, weight increases; And it is not high to produce output in batches; Utilization rate to material is also limited, thereby has improved the exploitation and the material cost of light fixture itself, has finally increased consumer's consumption burden; Same; If the weight of this LED lighting is bigger, put on so and use the load of this LED lighting also to become greatly, therefore must solve the problem of the support strength that improves ligthing paraphernalia.
This shows that above-mentioned existing LED bulb-shaped lamp obviously still has inconvenience and defective in structure and use, need further to improve.In order to solve the problem of above-mentioned existence, relevant manufacturer there's no one who doesn't or isn't seeks solution painstakingly, but does not see for a long time always and use effective solution, seriously hampers the development of industry.Therefore how to design a kind of LED bulb-shaped lamp of new structure, real one of the current important research and development problem that belongs to also becomes current industry and is badly in need of improved target.
For overcoming the deficiency of above traditional LED lamp thermal louver body structure; Engineers is developed the LED lamp of new construction through long-term exploration and test, make its heat dispersion be improved significantly; Improve its usability and life-span greatly, also reduced the cost of exploitation and material simultaneously.
