Abstract
The utility model discloses a high-efficiency radiating LED bulb, which mainly comprises a lampshade, a lamp cup and a lamp holder. A power source is arranged in the lamp holder, the lamp cup is mounted on the lamp holder, a PCB (printed circuit board) is arranged in the lamp cup, the transparent lampshade is mounted on the lamp cup, and radiating fins are arranged on the inner wall and the outer edge of the lamp cup and are arrayed into a vortex shape. A plastic connecting part is arranged between the lamp holder and the lamp cup, the plastic connecting part is in threaded connection with the lamp cup, the transparent lampshade is an optical-level light diffusion type transparent PC (polycarbonate) lampshade, and the PC lampshade is in threaded connection with the lamp cup. After the LED bulb is produced according to the technical scheme, the vortex radiating fins arranged on the inner wall and the outer edge of the lamp cup made of aluminum alloy materials and a thickened bottom casing contacting with the PCB are favorable for radiating of the LED bulb, and accordingly the problem of poor radiating of an existing LED bulb is solved. Further, the optical-level optical diffusion type PC lampshade has better light transmitting effect, is not easy to be broken and safer in use, and brings more convenience to popularization and application.
Description
Technical field
The utility model relates to and a kind ofly substitutes the bulb be used for traditional lighting by light emitting diode, and what relate to is can effectively remove LED to generate heat, so that its replace traditional bulbs operate as normal.
Background technology
By the LED that semiconductor constitutes, having electric current to flow through this LED will be luminous.At first sight, should do fabulous substituting to traditional tungsten lamp as LED, on equal power, they provide the light output more much more than incandescence.Same, the power of their use much less sends the light of equivalent.And their service life is the bigger order of magnitude.Be ten thousand hours vs.1-2 of 1-10 thousand hours.Yet LED has some shortcomings to cause them also not to be widely adopted substituting as incandescent lamp so far.Wherein main is, though LED needs the power of much less than incandescent lamp for a certain given light output, it also is to use a lot of wattages could generate the light that sufficient light is used.And the tungsten filament in the incandescent lamp bulb is worked on the temperature of general 3000 degree.Because LED is a semiconductor, is impatient at than about 120 degrees centigrade of hotter temperature.Thereby LED has an important heat problem, if work in a vacuum as incandescent lamp, even perhaps in air, it can overheat rapidly and quit work.This has been restricted to low-down power with the usable LED bulb, thus because the problem of LED bulb heat radiation, give the LED bulb use and popularization brings inconvenience.
The utility model content
The purpose of this utility model is in order to overcome the deficiencies in the prior art, provides a kind of effective removal LED to generate heat, and it is simple in structure, and is with low cost; And can make the LED bulb of its replace traditional bulbs work.
The utility model is implemented by the following technical solutions:
The LED bulb of high efficiency and heat radiation mainly comprises lampshade, Lamp cup and lamp holder, it is characterized in that: power supply is set in the lamp holder; Lamp cup is installed on the lamp holder, pcb board is set in the Lamp cup, Transparent lamp shade is installed on the Lamp cup, the inwall and the outer of described Lamp cup are provided with fin, and this fin is provided with along the inwall and the outer array of Lamp cup.
Described Transparent lamp shade is a light diffused PC lampshade, and this PC lampshade is threaded with described Lamp cup.
Described PC lampshade is the transparent PC lampshade of optical grade.
Described Lamp cup is the Lamp cup of aluminum alloy material.
One plastic cement connector is set between described lamp holder and the Lamp cup, and this plastic cement connector is threaded with the Lamp cup utilization.
LED bulb behind the employing such scheme, at first the Lamp cup inwall of aluminum alloy material and outer all are provided with the design of cyclone radiating fins, and the drain pan that contacts with pcb board of thickening, more help the heat radiation of LED bulb, solved the bad problem of existing LED bulb heat radiation, secondly the light diffused PC lampshade of optical grade has good translucent effect, and is not easy fragmentation, uses safer; To popularization with bringing many facilities.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a decomposing schematic representation of the present utility model.
The specific embodiment
As depicted in figs. 1 and 2: the LED bulb of high efficiency and heat radiation, mainly comprise lampshade 1, Lamp cup 3 and lamp holder 6, power supply 4 is set in the lamp holder 6; Lamp cup 3 is installed on the lamp holder 1, pcb board 2 is set in the Lamp cup 3, Lamp cup 3 utilizes aluminum alloy material one-body molded, and the inwall of Lamp cup 3 and outer are provided with fin 9, the fin of this fin for being arranged to the whirlwind type along the inwall and the outer array of Lamp cup 3.Transparent lamp shade 1 is installed on the Lamp cup 3, and Transparent lamp shade is the light diffused PC lampshade of optical grade, and the PC lampshade utilizes screw thread 7 to be connected with Lamp cup 3.One plastic cement connector 5 is set between lamp holder 6 and the Lamp cup 3, and this plastic cement connector 5 utilizes screw thread 7 to be connected with Lamp cup 3.Fix with traditional button bit, install more stablely, dismantle more convenient.LED bulb in the utility model, at first the Lamp cup inwall of aluminum alloy material and outer all are provided with the design of cyclone radiating fins, and the drain pan that contacts with pcb board of thickening, more help the heat radiation of LED bulb, solved the bad problem of existing LED bulb heat radiation, secondly the light diffused PC lampshade of optical grade has good translucent effect, and is not easy fragmentation, uses safer; To popularization with bringing many facilities.
