Background technology
LED (Light Emitting Diode), light emitting diode is a kind of solid-state semiconductor devices, it can directly be converted into light to electricity.The heart of LED is a semi-conductive wafer, and an end of wafer is attached on the support, and an end is a negative pole, and the other end connects the positive pole of power supply, makes entire wafer by epoxy encapsulation.Semiconductor wafer is made up of two parts, and a part is a P-type semiconductor, occupies an leading position in its hole, the inside, and the other end is a N-type semiconductor, mainly is electronics here.But when these two kinds of semiconductors couple together, just form a P-N knot between them.When electric current acted on this wafer by lead, electronics will be pushed to the P district, and electronics will send energy with the form of photon, the luminous principle of LED that Here it is then with hole-recombination in the P district.And the light wavelength color of light just is by the material decision that forms the P-N knot.
LED is directly had the following advantages as lighting: 1, the LED consumed energy reduces 80% with the incandescent lamp of light efficiency; 2, LED does not have poisonous metal mercury, can not pollute environment; 3, LED uses low-tension supply, and supply voltage is between 6-24V, and is different and different according to product, so it is a safer power supply of ratio use high voltage source, is specially adapted to public place and family and uses.
But when LED is used as light fixture, during especially as the light source of cylindricality light fixture, need the huge light emitting diode of usage quantity, these light emitting diodes are when guaranteeing brightness of illumination, also can produce huge heat, might damage circuit board and lead if a large amount of long-pending heat can not derive timely, influence the service life of light fixture.
Summary of the invention
The present invention has designed a kind of cylindrical LED lamp that is provided with special radiating device, the technical problem of its solution: (1) traditional cylindrical LED lamp may give out a large amount of heats, if the untimely derivation of these harmful heats might have influence on the service life of light fixture; (2) traditional cylindrical LED lamp needs a large amount of problems of using light emitting diode.
In order to solve the technical problem of above-mentioned existence, the present invention has adopted following scheme:
A kind of cylindrical LED lamp that is provided with special radiating device, comprise body, circuit board, a plurality of light emitting diode and branch sleeve, described a plurality of light emitting diode is installed in described circuit board, described circuit board is placed in the described body, be provided with a diffusion tabula rasa in the described body, described diffusion tabula rasa is arranged in the below of described a plurality of light emitting diodes and is installed in holddown groove on the described body; Described body top has an opening, the opening that one heat abstractor passes on the described body is connected with described circuit board, described heat abstractor comprises metal box, radiator liquid, radiating fin and mounting bracket, described radiator liquid is arranged in described metal box, and described radiating fin is between described metal box and described mounting bracket.
Further, described radiator liquid is a water.
Further, described body is provided with one deck nano fluorescent bisque.
Further, described body is the plastics with light transmission.
Further, described branch sleeve is provided with plug.
This cylindrical LED lamp that is provided with special radiating device is compared with traditional cylindrical LED lamp, has following beneficial effect:
(1) the present invention is owing to be provided with a heat abstractor specially, and this heat abstractor can go out long-pending thermal conductance in the light fixture timely and effectively, prolongs the service life of light fixture.
(2) the present invention is owing to be provided with one deck nano fluorescent bisque on body, thereby the use that the light that this nano fluorescent bisque can make light emitting diode send is softer or can save LED quantity strongly, perhaps be arranged to the cylindrical LED lamp of different colours, to meet the different needs.
