Abstract

The invention provides a large-luminosity-angle spherical bulb with diamond light-emitting surfaces, comprising a lamp head insulating body, a lamp body, a lamp shade, a diamond polyhedron and LED (Light-Emitting Diode) light-emitting component and an in-bulb cooling device, wherein the lamp body connects the in-bulb cooling device and the lamp head insulating body; the lamp shade is matched withthe in-bulb cooling device; the diamond polyhedron and LED light-emitting component is arranged near the center in the lamp shade and is combined by substrates, flexible connecting bridges, a diamondpolyhedral heat-conducting installing body; the substrates are provided with LED light sources, and the front surfaces of the substrates are provided with welding points used for connecting; the flexible connecting bridges are connected among the substrates through circuits; the diamond polyhedral heat-conducting installing body is diamond-like and has N sides, can be used for fixing a light-emitting component and can be set into any angle and shape; and the in-bulb cooling device is communicated with the lamp head, the lamp body and the lamp shade to form an airflow inlet and outlet channel.In the large-luminosity-angle spherical bulb provided by the invention, the lamp shade is designed into a shape larger than a hemisphere, which can increase a light-transmitting angle, the LED light-emitting component is made into a diamond structure so as to realize multidirectional positive and negative surface irradiation, and the in-bulb cooling device can carry out forced air-cooling on the in-bulb radiating fins and radiating fins in the lamp body.

Description

technical field [0001] The invention belongs to the technical field of electronics, and relates to a bulb lamp, in particular to a bulb with a large luminosity angle and a diamond body light-emitting surface. Background technique [0002] In the existing LED high-luminosity angle bulb lamps, the LED light sources are generally arranged in a plane layout and installed on the lamp body provided with a cooling device. The disadvantage of this structure of LED bulbs is that this type of LED is directly welded with multiple LED light-emitting diodes on a flat substrate, then installed on a heat dissipation base, and then covered with a lampshade and lens for light distribution. . Since the LED light-emitting diode is a point light source with a fixed angle, its light intensity value changes from high to low from the center to both sides, so the light output angle of the LED lamp is limited; the lens is also limited to adjust the light output angle, and it is difficult to obtain ...

Problems solved by technology

The disadvantage of this structure of LED bulbs is that this type of LED is directly welded with multiple LED light-emitting diodes on a flat substrate, then installed on a heat dissipation base, and then covered with a lampshade and lens for light distribution.

Since the LED light-emitting diode is a point light source with a fixed angle, its light intensity value changes from high to low from the center to both sides, so the light output angle of the LED lamp is limited; the lens is also limited to adjust the light output angle, and it is difficult to obtain a large light output angle.

And it is assembled on the plane of the heat sink. Due to the plane layout, it is impossible to adjust the angle at all. It is difficult to achieve more than 180°
