Abstract
The utility model discloses an LED bulb with a large illuminating surface, which comprises a lamp holder, a radiator, an LED chip and a lamp shade. The radiator is fixed to the lamp holder, the LED chip is fixed to the top of the radiator, a folded edge protrudes upwards from the top edge of the radiator, an annular wall is bent inward from the bottom edge of the lamp shade, and the lower end of the annular wall is clamped to the folded edge at the top edge of the radiator. The LED bulb is simple in structure and low in cost, and has a larger illuminating surface so that illumination range is enlarged.
Description
Technical field
The utility model relates to LED bulb technologies field, refers in particular to a kind of LED bulb of big plane of illumination.
Background technology
In the prior art, the LED bulb comprises lamp holder, radiator, led chip and lampshade, and radiator is fixed on the lamp holder, and led chip is fixed in the radiator top, and lampshade is fixed in the radiator top.Add the restriction of heat spreader structures, the fillet meeting stop portions light at radiator top, the LED bulb can only be selected the lampshade of cambered surface less than the hemisphere curved surface for use, the lighting angle and the plane of illumination of LED bulb have been limited, LED bulb light illumination range can only cover less than hemispheric zone, the lighting angle of LED bulb is less, and the LED bulb light is shown up less, and illumination range is little.Therefore, the LED bulb of prior art has improved needs.
The utility model content
The purpose of this utility model is to provide at the deficiencies in the prior art a kind of LED bulb of big plane of illumination, and it is simple in structure, and the LED bulb has bigger lighting angle and plane of illumination, improves illumination zone.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of LED bulb of big plane of illumination, comprise lamp holder, radiator, led chip and lampshade, radiator is fixed on the lamp holder, led chip is fixed in the radiator top, the radiator top flanging that raises up, the direction bending to the inside of the bottom margin of lampshade goes out an annular wall body, and the lower end of annular wall body is connected in the flanging of radiator top.
Described flanging is the annular thin wall body.
The arcwall face of described lampshade is greater than the hemisphere curved surface.
Described flanging upper end direction to the inside tilts.
The inwall of described flanging is provided with catching groove, and the lower end of annular wall body is provided with the button pin, and the button pin protrudes the outer wall at the ring wall body, and the button pin is connected in the catching groove.
The beneficial effect that the utility model has owing to the employing technique scheme: the utility model is simple in structure, and cost is low, and the LED bulb has bigger lighting angle and plane of illumination, the raising illumination zone.

The specific embodiment
The embodiment of the LED bulb of a kind of big plane of illumination of the present utility model is seen shown in Fig. 1 to 3, comprise lamp holder 1, radiator 2, led chip 3 and lampshade 5, radiator 2 is fixed on the lamp holder 1, led chip 3 is fixed in radiator 2 tops, the radiator 2 top flanging 4 that raises up, flanging 4 is the annular thin wall body, and flanging 4 upper ends direction to the inside tilt.
The arcwall face of lampshade 5 is greater than the hemisphere curved surface, and the direction bending to the inside of the bottom margin of lampshade 5 goes out an annular wall body 6, and the lower end of annular wall body 6 is connected in the flanging 4 of radiator 2 top.
The inwall of flanging 4 is provided with catching groove, and the lower end of annular wall body 6 is provided with button pin 7, the outer wall that button pin 7 protrudes at the ring wall body, and button pin 7 is connected in the catching groove.
Certainly, the clasp of annular can also be set in the lower end of annular wall body 6, clasp buckled in catching groove when lampshade 5 was fixed in radiator 2 tops.
The utility model is simple in structure, cost is low, the flanging 4 at radiator 2 tops does not stop light, and the arcwall face of lampshade 5 greater than hemisphere bent and, annular wall body 6 reverse reflex of lampshade 5 lower ends, the light that the LED bulb sends has bigger coverage, the illumination range of LED bulb covers greater than hemispheric zone, LED bulb lighting angle is big, and illumination Zhou Gengda improves illumination zone.
Above content only is preferred embodiment of the present utility model, for those of ordinary skill in the art, according to thought of the present utility model, the part that all can change in specific embodiments and applications, this description should not be construed as restriction of the present utility model.
