Description

The LED incandescent lamp

Technical field

The utility model relates to a kind of lighting, is specifically related to a kind of LED incandescent lamp.

Background technology

Lighting is one of indispensable daily necessities of institute in people's daily life, and just because of lighting has been arranged, people can carry out work, study, life and amusement like one ground on daytime in night.Traditional lighting mostly is an incandescent lamp, and its ball bubble is shaped as popular institute to be liked, and still, the light efficiency of incandescent lamp is low, useful life short, thereby has restricted the use of incandescent lamp.LED (English is Ught emitting diode) is a light emitting diode; A kind ofly adopt electroluminescent semi-conducting material manufacturing to form, LED has good characteristics such as voltage is low, usefulness is high, monochromaticjty is good, applicability is strong, good stability, the response time is short, the life-span is long, free from environmental pollution; Adopt the low-tension supply power supply under one situation of LED, supply voltage one between 2-24V, have more security; The LED consumed energy reduces 80% with the incandescent lamp of light efficiency; Each unit LEDs is very little, can be prepared into the ligthing paraphernalia of different shape, and is suitable for different environment; Have good characteristic as above just because of LED, so LED has been widely used in the fields such as illumination, decoration.But, in existing lighting field, the LED lamp of the imitative conventional incandescent bulb of Shang Weiyou; If after the LED lamp being made into the shape of incandescent lamp; Because vacuum was taken out in incandescent lamp inside, it damages under hot operation easily, and also breaks easily; Casualty accident occurs, so the security performance of incandescent lamp is lower.

Summary of the invention

To the problems referred to above, the purpose of the utility model is to provide a kind of safe and reliable, LED incandescent lamp that shape is identical with incandescent lamp.

The technical scheme that realizes above-mentioned purpose is following:

A kind of LED incandescent lamp comprises screwed socket, lampshade, circuit board, it is characterized in that: said circuit board is an independently polylith of difference; The first circuit board that wherein is provided with some LED adopts 3～6; The polylith first circuit board is by the skeleton support fixation, and the second circuit board that is provided with some LED is positioned at skeleton one end, and the tertiary circuit plate is positioned at the skeleton other end; Said skeleton is pegged graft in opposite directions by upper skeleton and lower skeleton two parts and is formed; The skeleton that fits together and second, third circuit board are fixedly connected with bulb socket through bolt, and lampshade covers first, second circuit board and is threaded with bulb socket, and the other end of bulb socket is installed screwed socket; Drive circuit is positioned at screwed socket and is fixed on the bulb socket, and said lampshade is a light penetrating object.

The polygonal circuit board that said first circuit board is surrounded by polylith LED paster.

The first circuit board cross section is regular hexagon.

Said drive circuit is made up of filter circuit and rectification circuit.

Second circuit board is the LED paster.

Upper skeleton and lower skeleton are cross section and are orthohexagonal cylindrical shell, and the surface on each limit of cylindrical shell is provided with a plurality of reinforcements, and the gap between each reinforcement is a heat dissipation channel.

Said lampshade is the lampshade of PC.

Therefore adopted such scheme, the profile of the utility model and the appearance similar of ordinary incandescent lamp can be taken into account the replacement with the traditional lighting light fixture, use the lamp holder the same with conventional incandescent, adaptation user use habit.The utility model is as lower powered LED light fixture, and the consideration of heat radiation just needs enough big radiator unlike high-power that kind, supplies cross-ventilation and only need enough spaces, produces heat exchange and gets final product.The heat that the utility model produces is less, only need have the air of convection current can satisfy heat radiation.In addition, the skeleton that fits together and second, third circuit board are fixedly connected with bulb socket through bolt, thereby; Vacuumize in when lampshade is installed, need not lampshade; Even lampshade breaks, can not form explosion accident yet, thereby provide the foundation for the security of LED incandescent lamp.Because lampshade and bulb socket thread connecting mode make assembling simple more, convenient.

Said first circuit board not only helps practicing thrift cost by the polygonal circuit board that polylith LED paster surrounds, and profile is comparatively attractive in appearance.

The utlity model has following characteristics:

1. solved the problem of low-power LED structural design;

2. take into account replacement with the traditional lighting light fixture;

3. use the lamp holder the same, adapt to user's use habit with conventional incandescent;

4. adopt the PC Transparent lamp shade, avoided the crackly shortcoming of conventional incandescent lamp lens outer cover;

5. the arrangement of low-power LED makes its luminance and ordinary incandescent lamp effect similar.
