Abstract
The utility model relates to the technical field of lamps, in particular to an LED tube lamp which comprises a tube body being of a round cup shape. The tube body is internally fixed with a light-emitting circuit board which is provided with a plurality of LED chips; and the outer wall of the tube body is molded with radiating fins. In the utility model, the outer wall of the tube body is molded with the plurality of radiating fins, so that the radiating area can be increased, and simultaneously, the heat can be transmitted at once, thus ensuring the safety of the lamp and prolonging the service life of the lamp.
Description
Technical field
The utility model relates to the lamp technical field, refers in particular to a kind of LED Down lamp.
Background technology
Current, the use of LED is very extensive, and wherein, LED shot-light, LED Down lamp are also very many.The LED Down lamp in use can produce a large amount of heats at short notice, and therefore, the LED Down lamp must have radiator structure preferably, just has to make product keep long service life.
Therefore, need a kind of LED Down lamp of design, it can distribute heat in the very first time, guarantee the safe in utilization of light fixture.
The utility model content
The purpose of this utility model is: provide a kind of LED Down lamp at the deficiencies in the prior art, this LED cylinder lamp structure is simpler, and it can distribute heat in the very first time, guarantee the safe in utilization of light fixture, prolongs the service life of light fixture.
For achieving the above object, the utility model is achieved through the following technical solutions:
It comprises cylindrical shell, and cylindrical shell is round cup shape, is fixed with luminous circuit board in the cylindrical shell, has a plurality of LED wafers on the luminous circuit board, forms radiating fin on the outer tube wall of cylindrical shell.
The upper limb place of described cylindrical shell has epitaxy part.
Upper limb place in the described cylindrical shell is embedded with backplate, and backplate is positioned at the upper end of luminous circuit board.
Described radiating fin has a plurality of, and radiating fin is along the surface that radially protrudes from cylindrical shell of cylindrical shell.
Described each radiating fin is parallel respectively, be located on the cylindrical shell outer tube wall.
The beneficial effects of the utility model are: adopt and mold a plurality of radiating fins on the outer tube wall of cylindrical shell, can increase area of dissipation, can the very first time heat be passed simultaneously, guarantee the safety of light fixture, prolong the service life of light fixture.
Description of drawings
Fig. 1 is a structural representation of the present utility model
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
See Fig. 1, the utility model LED Down lamp comprises: cylindrical shell 1, and cylindrical shell 1 is round cup shape, and the upper limb place of cylindrical shell 1 has epitaxy part, and epitaxy part is located on the upper limb of cylindrical shell 1; Be fixed with luminous circuit board 3 in the cylindrical shell 1, have a plurality of LED wafers on the luminous circuit board 3, the nearly upper limb place in the cylindrical shell 1 is embedded with backplate 4, and backplate 4 is positioned at the upper end of luminous circuit board 3, and backplate 4 can play the leaded light effect; Form radiating fin 2 on the outer tube wall of cylindrical shell 1, radiating fin 2 has a plurality of, and radiating fin 2 is along the surface that radially protrudes from cylindrical shell 1 of cylindrical shell 1, and each radiating fin 2 parallel respectively, be located on cylindrical shell 1 outer tube wall.
The utility model radiating effect is better, and service life is longer.
Certainly, the embodiment of the above, it is preferred embodiments of the present utility model, and unrestricted the utility model practical range, so all equivalences of doing according to the described structure of the utility model claim, feature and principle change or modify, and all should be included in the utility model claim.
