Abstract

The utility model discloses a G9-light-emitting diode (LED) bulb. The G9-LED bulb comprises a base seat, a driving component, an outer shell, an LED lamp plate and a lampshade, and is characterized in that the outer shell is formed by a round barrel and a square shaft in a connection mode, an opening of the round barrel of the outer shell is connected with the base seat in a sleeved mode, the driving component is arranged inside the round barrel, surface mounted device (SMD) LED chips are arranged in five directions of the square shaft of the outer shell, and the lampshade covers all the SMD LED chips on the square shaft and is sleeved with the bottom of the round barrel of the outer shell. According to the technical scheme, the outer shell is made of ceramic materials in a sintering mode, every two SMD LED chips are respectively arranged on four sides of the square shaft of the outer shell, and one SMD LED chip is respectively arranged on the top end of the square shaft. The G9-LED bulb is obvious in power-saving effect, strong in heat conductivity, and easy in heat dissipation. The SMD LED has the feature of soft light, enables people to feel comfortable in vision, is high in light effect, and accords with the idea of environment protection. Meanwhile, the purposes of good heat-dissipation performance and good insulation performance are achieved.

Description

The G9-LED bulb

Technical field

The utility model relates to a kind of bulb, relates in particular to the bulb of a kind of LED.

Background technology

Because LED has economize on electricity, the life-span speciality, environmental protection etc. advantage, the LED bulb continues to bring out various new products, substitute former in vehement lamp and Halogen lamp LED, originally the Halogen lamp LED power consumption of G9 model is up to tens watts, if adopt the LED bulb just to only have all watt, but existing LED bulb is because the inherent structure of LED itself, often can only be in the bright dipping of the dead ahead of bulb, the direction of its irradiation and angular range all are subject to larger restriction, patent No. CN200910039738.8 " a kind of LED bulb of multifaceted light-emitting " also points out this shortcoming, for this reason this patent Introduction a kind of direction of illumination and angular range large, the LED bulb of the multifaceted light-emitting of excellent in heat dissipation effect, but because adopt high-power LED, the heat of generation is large, heat radiation or insufficient, the soften of light is also undesirable.

Summary of the invention

The purpose of this utility model is for the above-mentioned shortcoming of prior art, provides like a kind of and original Halogen lamp LED G9 model outer appearnce, has all G9-LED bulbs large, excellent in heat dissipation effect of direction of illumination and angular range.

The purpose of this utility model is to realize by following technical scheme:

The G9-LED bulb, include base, driven unit, shell, LED lamp plate, lampshade, it is characterized in that: described base has two pins that connect power supply, described shell is the connector of a cylinder and square shaft, it is core technology of the present utility model, the mouth cylinder of shell and base socket, cylinder interior is mounted with driven unit, five directions of the square shaft of shell are settled SMD LED paster, described lampshade is that transparent plastic is made, all SMD LED pasters on square shaft are covered, be nested with the bottom of cylinder of shell.

Shell forms with the ceramic material sintering, settles each two of SMD LED pasters above square shaft four limits of shell; Settle SMD LED paster a slice above the square shaft top, driven unit is placed in the cylinder of shell, one of driven unit connects power pin, the other end connects the SMD LED paster above the LED lamp plate, and the mouth cylinder cover of shell is caught base, and bottom of cylinder and the lampshade of shell are nested, lampshade is that transparent plastic is made, all SMD LED paster covers inside, base is inserted with on the lamp socket of power supply, the light that bulb just sends and softens.

The invention has the beneficial effects as follows:

1, based on halogen bulb changes the LED bulb into, and saves energy selects the SMD LED paster as light emitting source again, power savings is more remarkable, because the single power of great power LED is more than 0.5 watt, and SMD LED paster is below 0.3 watt, power consumption is lower, it is to be close on the lamp plate that SMD LED paster is settled, so the heat conductibility is strong, it is easier to dispel the heat, SMD LED paster itself has the soft characteristics of light, make people's vision more comfortable, light efficiency is also higher, meets the theory of environmental protection.

Even 2, change SMD LED paster into by the LED bulb on the LED lamp plate, also can produce heat, why shell has selected ceramic material, because ceramic material is one of heat radiation optimum carrier that is only second on metal, it is again best insulator, so this technical scheme has solved should excellent heat dissipation performance, the difficult problem of good insulation preformance again simultaneously.
