Embodiment Construction

[0017] As shown in Figure 1-2, the LED lighting bulb of the present invention includes a lamp socket 1, an isolation column 2, a radiator 3, a light source base 4, a plurality of LED lamps 5, an insulating aluminum substrate 6 and a glass lamp shell 7. The lamp socket 1 and the isolation column 2 are connected by threads, so that when the lamp socket 1 is broken, only the lamp socket 1 needs to be replaced, and there is no need to replace all of it. The lamp socket 1 is equipped with an AC-DC converter 8 for AC-DC conversion. The device 8 outputs a DC voltage of 5-30v to provide a plurality of LED lights 5, so as to ensure that the use voltage is within a safe voltage range.

[0018] The isolation column 2 is connected to the radiator 3, and the radiator 3 is connected to the light source base 4. The radiator 3 is circular in shape with a through hole in the center. The heat sink 3 is close to the light source base 4 and the heat is high. The light source base 4 has low heat, so t...

Abstract

The invention relates to a LED lighting bulb, which comprises a socket, a separating pillar, a radiator, a light source base, a plurality of LED lamps, insulated aluminum base plates and a glass lamp housing, wherein, the socket is connected with the separating pillar connected with the radiator; the radiator which is round is connected with the light source base, and the center of the radiator is provided with a via hole; a thermal conductive pillar connected to the via hole is arranged at the back end of the light source base; the insulated aluminum based plates uniformly provided with a plurality of LED lamps are connected with the front end center of the light source base; the glass lamp housing, the inner surface of which is coated with a layer of reflection grinding powder, is connected with the light source base. The invention has the advantages of large luminous area, soft light, low power consumption without mercurial pollution, good heat dissipation, low surface temperature of the lamp, good safety, convenient operation and long life, without needing to install accessories of the prior fluorescent lamp such as ballasts, starters, etc., and the start-up of the bulb free from influence of temperatures and on-off times.

Description

Technical field [0001] The invention relates to a lighting bulb, in particular to an LED lighting bulb. Background technique [0002] At present, the available energy is limited and energy waste is serious. The development of high-efficiency, energy-saving, and environmentally friendly light sources has become an effective way to solve the problem of energy shortage. Due to the characteristics of low power consumption, high luminous brightness, low cost, and long service life, light-emitting diodes can well replace traditional lighting sources to achieve the purpose of greatly reducing costs and saving energy. However, the light-emitting diode itself has its own shortcomings: [0003] 1. Luminescence is a beam of light in a single direction, but daily lighting needs to diverge; [0004] 2. High-power LEDs generate high heat, which seriously affects the lighting time and life of LEDs; [0005] 3. The light-emitting diodes have high luminous intensity, which is easy to hurt people'...
