Abstract
The utility model relates to an LED (light-emitting diode) bulb lamp with large-angle luminescence, comprising a lamp holder. The lamp holder is provided with a radiator shell which is connected with a shading cover; the top of the radiator shell is provided with a trapezoidal radiator with a cylindrical section; lamp bulbs are arranged on the top and the trapezoidal part of the radiator; since a plurality of aluminium substrates are arranged at different angles, the light-emitting angle of the LED bulb lamp is larger than 180 degrees, and good effects of expanding the light angle of the LED bulb lamp and improving illumination distribution are achieved; and in addition, since the radiator is designed into a trapezoidal shape with a cylindrical section, the contact area between the radiator and the radiator shell is increased, the radiating efficiency of the LED bulb lamp is improved, and the LED bulb lamp is beneficial to ensuring safety and the service life is the LED bulb lamp prolonged.
Description
Technical field
The utility model relates to a kind of lighting device, is specifically related to the luminous LED bulb lamp of a kind of wide-angle.
Background technology
At present, the lamp pearl in the LED bulb lamp generally is to be welded on the same aluminium base, is on the same horizontal plane.LED is a point light source light-emitting, and its side and rear are not luminous, and the method that generally adopt this area is to cooperate shade to widen luminous angle.Because the lamp pearl is on the same aluminium base that is welded on, and is on the same horizontal plane, its lighting angle is restricted, even if add the optical filtering lampshade, lighting angle is 180 ° to the maximum, and Illumination Distribution is also very undesirable.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of wide-angle emitting led bulb lamp, and it is wide to have a lighting angle, is fit to room lighting, and the radiating efficiency height, safe and reliable and characteristics that the life-span is long.
To achieve these goals, the technical scheme that the utility model adopted is: the LED bulb lamp that a kind of wide-angle is luminous, comprise lamp socket 6, lamp socket 6 is provided with radiator shell 5, radiator shell 5 is connected with light shield 1, be provided with circular cylindrical cross section at the top of radiator shell 5 and be trapezoidal radiator 4, be provided with lamp pearl 2 at radiator 4 tops and terraced portion, lamp pearl 2 is separately fixed on different aluminium base 3.
Described lamp pearl 2 is fixing with radiator 4 by aluminium base 3.
Described aluminium base 3 is at least 2.
Because polylith aluminium base 2 is installed in different angles, the lighting angle of lamp pearl 2 is greater than 180 °, reached and widened lighting angle and improve the Illumination Distribution good result, as shown in Figure 4, the utility model Illumination Distribution curve b is near 290 °, and the Illumination Distribution curve a of existing LED bulb lamp is not more than 180 °; Because radiator 4 is designed to circular cylindrical cross section is trapezoidal, increased the contact area of radiator 4 with radiator shell 5, improved radiating efficiency, help security and life-saving.
Description of drawings
Fig. 1 is the prior art products side view.
Fig. 2 is a profile of the present utility model.
Fig. 3 is a vertical view of the present utility model.
Fig. 4 is Illumination Distribution figure.
Among the figure: 1 is light shield, and 2 is the lamp pearl, and 3 is aluminium base, and 4 is radiator, and 5 is radiator shell, and 6 is lamp socket, and a is the Illumination Distribution curve of existing LED bulb lamp, and b is the utility model Illumination Distribution curve.
The specific embodiment
Below in conjunction with drawings and Examples structure of the present utility model and operation principle are described further.
Referring to Fig. 1,2,3, the LED bulb lamp that a kind of wide-angle is luminous, comprise lamp socket 6, lamp socket 6 is provided with radiator shell 5, radiator shell 5 is provided with light shield 1, the top of the radiator shell 5 in light shield 1 is provided with circular cylindrical cross section and is trapezoidal radiator 4, is provided with lamp pearl 2 at radiator 4 tops and terraced portion.
The lamp pearl is separately fixed on the aluminium base 2, because polylith aluminium base 2 is installed in different angles, makes the lighting angles of 9 lamp pearls 2 greater than 180 °, has reached the good result of widening lighting angle and improving Illumination Distribution.Because radiator 4 is designed to circular cylindrical cross section is trapezoidal, increased the contact area of radiator 4 with radiator shell 5, improved radiating efficiency, help security and life-saving.
