Description

The LED bulb
Technical field
The present invention relates to a kind of LED bulb.
Background technology
Traditional bulb is an incandescent light bulb, and its illumination is lower, and light is not bright, not energy-conservation.Occurred the fluorescent lamp bulb behind incandescent lamp bulb, though it is energy-conservation, light is brighter, since a large amount of fluorescent material that uses, therefore not enough environmental protection.Occurred more energy-conservation at present and led light source environmental protection, produced the LED bulb thereupon, existing LED bulb common configuration complexity, mainly comprise three parts---lamp holder, neck, luminous sphere, lamp holder all is a standard component, neck generally has plastics and two kinds of materials of metal, neck generally is lighttight, be mainly used in and connect and heat radiation or placement driver, luminous sphere generally has two kinds of materials of plastic and glass, is used for printing opacity, and generally needs additionally to set up heat abstractor, heat abstractor generally can see from the outside and profile strange, so its profile has been compared than big difference with the ordinary incandescent lamp bulb with internal structure.
In the existing LED bulb, the light emission direction of LED generally all is forward, owing to be subjected to the restriction of LED lighting angle, therefore existing LED bulb is luminous all a taper angle, can not be the same with the fluorescent lamp bulb luminous to all directions as traditional incandescent light bulb.After using the LED bulb to replace incandescent light bulb and fluorescent lamp bulb and putting it into light fixture, because the difference of illumination mode can cause illumination effect and incandescent light bulb and fluorescent lamp bulb to differ greatly, can not reach the illumination effect of Design of Luminaires, decorate properties is had a greatly reduced quality, and therefore can the replacement of bulb be had a negative impact.In addition, existing LED bulb is in order to reach the requirement of high brightness, a fairly large number of LED need be set, because the space is less in the bulb, in order to save the space, therefore generally the LED staggered superposition is arranged, can be interfered mutually when each LED is luminous and refraction and reflection take place, this can cause its light transmittance relatively poor again, and illumination effect is poor.
Summary of the invention
Technical problem to be solved by this invention is to overcome the deficiencies in the prior art, provide a kind of light transmittance energy good, the identical LED bulb of illumination mode and volume, profile and ordinary incandescent lamp bulb, described LED bulb appearance looks elegant, simple in structure, energy-saving and environmental protection, good heat dissipation effect, can be luminous to all directions, illumination effect is good.
The technical solution adopted in the present invention is: the present invention includes lamp holder, cell-shell, the afterbody of described cell-shell and described lamp holder are fixedly connected, described LED bulb also comprises the drive circuit assembly, light source bracket, led light source, described drive circuit assembly is positioned at described lamp holder, described cell-shell is enclosed in inner chamber with described led light source and described light source bracket, described light source bracket comprises base, polyhedron, described light source bracket adopts the metal manufacturing, the inside axial centre of described base is provided with wire hole, described polyhedron is positioned at the top of described base, the bottom of described base closely contacts mutually with the inwall of described lamp holder and carries out heat conduction, described led light source comprises radiating bottom plate and is positioned at led chip on the described radiating bottom plate, described radiating bottom plate directly is fixed on described polyhedral circumferentially each face, described led chip with described polyhedral circumferentially each face be datum level to around luminous, described drive circuit assembly is electrically connected by lead and described lamp holder and passes described wire hole and described led light source is electrically connected by lead.
Described radiating bottom plate also directly is fixed on described polyhedral end face, and described led chip is that datum level is luminous with described polyhedral end face also.
Described led light source is positioned at the centre of luminescence of described cell-shell.
The profile of described base is bent taper or pyramid is cylindrical or prismatic.
The described cell-shell structure that is formed in one.
Perhaps, described cell-shell comprises upper body, lower case, and described upper body and described lower case are fastened and connected or bond fixing.
Complete printing opacity of described cell-shell or part printing opacity.
