Description

A kind of LED steeps modulated structure

Technical field

The utility model relates to a kind of LED, and espespecially a kind of LED steeps modulated structure.

Background technology

Traditional incandescent lamp lighting angle is larger, but relative LED, and energy consumption height is short for service life, and the LED that the market of present European and American areas is sought after wide-angle steeps lamp and carrys out alternative traditional incandescent lamp.

But the light emitting anger of LED chip generally only has about 120 degree, larger lighting angle be reached, can dispersing of scioptics allow angle become large, but the light that scioptics send be generally uneven, visually has obvious light and shade light.

A kind of method is also had to be carry out diffusion angle by a milky white cell-shell.As shown in Figure 1, be existing common LED lamp structure, the LED chip of this LED be placed on cell-shell 2' bottom near, cell-shell 2' is arranged on the lamp body 3' for dispelling the heat, and lamp body 3' is also provided with lamp holder 4'.By the diffusion of cell-shell 2', the light emitting anger of 120 degree originally can be made to be diffused into about 170 degree.But the light emitting anger of 170 degree still can not meet the requirement of European and American areas to lighting angle.

Therefore, just occurred that LED as shown in Figure 2 steeps lamp, which increase cell-shell 2 ' ' height, change the curvature of cell-shell bottom opposite upper parts simultaneously, so both ensure that light emitting anger was diffused into about 270 degree, again ensure cell-shell 2 ' ' width do not exceed regulation requirement, when bubble degree 2 ' ' when highly increasing, the lamp body 3 ' ' volume then can reduce (lamp holder 4 ' ' of its underpart heat radiation highly has definite value to require), area of dissipation will inevitably be reduced, and then affect the service life that LED steeps lamp, be unfavorable for the setting of the LED bubble lamp that wattage is large.

Utility model content

The purpose of this utility model is to provide a kind of LED bubble modulated structure that can increase lighting angle and can ensure again to dispel the heat.

For achieving the above object, solution of the present utility model is:

A kind of LED steeps modulated structure, it LED chip comprising a lamp body, be engaged in the lamp holder of lamp body one end, be engaged in the cell-shell of the lamp body other end and be arranged on bottom cell-shell, and this LED chip is mounted in the lamp body top that genesis analysis has radiating fin; Wherein: the radiating fin of described lamp body be interval be extended with dog to cell-shell direction.

Described each dog is that the outline extension of laminating cell-shell bottom forms.

The circumference external diameter that described each dog is formed is less than or equal to the maximum outside diameter size of cell-shell.

Described lamp body is a trumpet type metal casing, and its outer peripheral edge is distributed with radiating fin, and the upper end of lamp body forms the end face coordinated for LED chip, and for the auxiliary section coordinated bottom cell-shell, inner space is for holding the electric elements such as wiring board.

Described cell-shell is a top is spherical crown, and the radius of curvature light-permeable shell large compared with spherical crown radius of curvature is formed at bottom.

Also arrange a lamp housing outside described lamp body, the dog position of the corresponding lamp body of lamp housing is also extended with convex pin to cell-shell direction.

Described lamp housing is a trumpet type case, and it adopts plastic material to make, and forms longitudinal convex tendon in its outer peripheral edge, forms groove to aim at each radiating fin inside convex tendon.

The auxiliary section coordinated with cell-shell is formed at the top of described lamp housing.

The circumference external diameter that described each convex pin is formed is less than or equal to the maximum outside diameter size of cell-shell.

After adopting such scheme, the dog of the utility model by being extended to form to cell-shell direction by the radiating fin of lamp body, effectively increases the heat radiation volume of radiating fin, improves the radiating efficiency of large-angle LED bubble lamp with this, ensure product service life, meet the instructions for use of high wattage bubble lamp; Each dog is set in distance, and can ensure that the bright dipping of cell-shell bottom is unaffected.

In addition, the circumference external diameter that each dog is formed is less than or equal to the maximum outside diameter size of cell-shell, can ensure that the outside dimension of overall light fixture is unaffected, meets the appearance requirement that LED steeps lamp.

Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.

As shown in Figures 3 to 6, the utility model discloses a kind of LED and steeps modulated structure, it LED chip 1 comprising a lamp body 3, be engaged in the lamp holder 4 of lamp body 3 one end, be engaged in the cell-shell 2 of lamp body 3 other end and be arranged on bottom cell-shell 2, this LED chip 1 is mounted in lamp body 3 top that genesis analysis has radiating fin 31; Key of the present utility model is:

The radiating fin 31 of described lamp body 3 is extended with dog 32 in interval to cell-shell 2 direction, and each dog 32 is that the outline of laminating cell-shell 2 bottom extends and forms, and the circumference external diameter that each dog 32 is formed is less than or equal to the maximum outside diameter size of cell-shell 2.

Described lamp body 3 is a trumpet type metal casing, and its outer peripheral edge is distributed with radiating fin 31, and the upper end of lamp body 3 forms the end face 33 coordinated for LED chip 1, and for the auxiliary section coordinated bottom cell-shell 2, inner space 34 is for holding the electric elements such as wiring board;

Described cell-shell 2 is a top is spherical crown, and the radius of curvature light-permeable shell large compared with spherical crown radius of curvature is formed at bottom.

In this enforcement, also arrange a lamp housing 5 outside lamp body 3, this lamp housing 5 is also a trumpet type case, and it can adopt plastic material to make, and forms longitudinal convex tendon 51 in its outer peripheral edge, forms groove 52 to aim at each radiating fin 31 inside convex tendon 51; The auxiliary section 53 coordinated with cell-shell 2 is formed at the top of lamp housing 5, and the while of lamp housing 5, dog 32 position of corresponding lamp body 3 is also extended with convex pin 54 to cell-shell 2 direction, and the circumference external diameter that each convex pin 54 is formed is less than or equal to the maximum outside diameter size of cell-shell 2.

The dog 32 of the utility model by the radiating fin 31 of lamp body 3 is extended to form to cell-shell 2 direction, the heat radiation volume of effective increase radiating fin 31, improve the radiating efficiency of large-angle LED bubble lamp with this, ensure product service life, meet the instructions for use of high wattage bubble lamp; Each dog 32 is the settings in interval, and namely its distribution density is less than the distribution density of radiating fin 31, to ensure the bright dipping of cell-shell 2 bottom, and does not affect rising angle and the brightness requirement that LED steeps lamp; In addition, the circumference external diameter that each dog 32 is formed is less than or equal to the maximum outside diameter size of cell-shell 2, can ensure that the outside dimension of overall light fixture is unaffected, meets the appearance requirement that LED steeps lamp.
