Abstract

The invention relates to an LED bulb. The LED bulb comprises a bulb holder, a PTB plastic casing, a substrate, a radiator, a PC bulb shade, an LED light source, a drive power supply and a light diffusion sheet. The substrate is arranged on the radiator and is connected with the drive power supply which is connected with the LED light source. The substrate and the radiator are arranged in the PTB plastic casing, the LED light source and the drive power supply are arranged in the PC bulb shade, and the PTB plastic casing is connected with the PC bulb shade. The light diffusion sheet covers the outer surface of the PC bulb shade. The LED bulb is good in radiation performance, long in service life and good in light emitting effect.

Description

A kind of LED bulb
Technical field
The present invention relates to a kind of bulb, be specifically related to a kind of LED bulb.
Background technology
LED light is as a kind of house lighting for alternative tengsten lamp and fluorescent lamp, because it has that energy consumption is little, light efficiency is large, without advantages such as mercury, radiationless pollution and material reproducible utilizations, in today of energy growing tension, be more and more subject to consumer's welcome.In the LED bulb using at present, radiator normally adopts many screws to be fixedly connected with pcb board, and this kind of connected mode assembly and disassembly are more loaded down with trivial details, and when fixed screw fragile pcb board also.Front LED bulb is applied very extensive on market, because the waste heat of LED bulb need to distribute from shell, common employing aluminium alloy is as heat-dissipating casing on the market, dispel the heat bad, skin temperature is overheated, the maintain and replace that is unfavorable for people, in addition due to metal shell, likely has the hidden danger of electric leakage.
Summary of the invention
For addressing the above problem, the invention provides a kind of LED bulb.
The technical scheme that the present invention solves the problems of the technologies described above is as follows: a kind of LED bulb, comprises lamp socket, PTB plastic casing, substrate, radiator, PC lampshade, LED light source, driving power and scattering sheet; Described substrate is on described radiator; Described substrate connects described driving power, and described driving power connects LED light source; Described substrate and radiator are in described PTB plastic casing; Described LED light source and driving power are in described PC lampshade, and described PTB plastic casing connects described PC lampshade; Described scattering sheet is wrapped up described PC lampshade outer surface.
Further, described PTB plastic casing and described PC lampshade are merged into lantern-shaped; Between described substrate and described radiator, be provided with a layer graphene; Described scattering sheet is that on transparent base, PET two sides is coated with astigmatic optics particle.
The invention has the beneficial effects as follows: a kind of LED bulb provided by the invention, perfect heat-dissipating, long service life, illumination effect is good simultaneously.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present invention;
In accompanying drawing, the list of parts of each label representative is as follows:
1, lamp socket, 2, PTB plastic casing, 3, substrate, 4, radiator, 5, PC lampshade, 6, LED light source, 7, driving power, 8, scattering sheet, 9, scattering sheet.
The specific embodiment
Below in conjunction with accompanying drawing, principle of the present invention and feature are described, example, only for explaining the present invention, is not intended to limit scope of the present invention.
As shown in Figure 1, a kind of LED bulb, comprises lamp socket 1, PTB plastic casing 2, substrate 3, radiator 4, PC lampshade 5, LED light source 6, driving power 7 and scattering sheet 8; Described substrate 3 is on described radiator 4, between described substrate 3 and described radiator 4, be provided with a layer graphene 9, Graphene has good heat conductivility, and heat is sent to radiator 4 heat radiations, guarantee to control the temperature of substrate 3, extend the service life of substrate 3.Described substrate 3 connects described driving power 7, and described driving power 7 connects LED light source 6, guarantees that the power supply of LED light source 6 is stable, prevents that voltage instability from causing burning out LED light source 6.
Described substrate 3 and radiator 4 are in described PTB plastic casing 2; Described LED light source 6 and driving power 7 are in described PC lampshade 5, and described PTB plastic casing 2 connects described PC lampshade 5, and described PTB plastic casing 2 and described PC lampshade 5 are merged into lantern-shaped, and integral body is the aesthetic feeling that lantern-shaped more contributes to outward appearance.Described PC lampshade 5 outer surfaces of described scattering sheet 8 parcel.Scattering sheet 8 is that on transparent base, PET two sides is coated with astigmatic optics particle, and LED light source 6 illumination can reach good astigmatism effect through scattering sheet 8, and the LED bulb illuminating area that is is larger, and the utilization rate of luminous energy is higher.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
