Abstract

An LED (light emitting diode) bulb with a screw socket mainly comprises the screw socket (8), a metal heat radiating plate (5), a lamp cover (7) and an aluminum-based PCB (printed circuit board) (6) with an LED surface mounted device. A driver consists of a driver shell (1), a driver PCB (3) and a driver plastic spacer (4), the driver PCB (3) is arranged in the driver shell (1) and fixed by the driver plastic spacer (4), and the upper portion of the driver shell (1) is provided with an external thread matched and connected with an internal thread of the screw socket (8). The driver is closely connected and fixed with the metal heat radiating plate (5) and the aluminum-based PCB (6) with the LED surface mounted device through four screws, and the lamp cover (7) is connected with a heat radiating base plate on the metal heat radiating plate (5) by rotating. By means of widening of the surface mounted device and transverse heat radiation, a heat radiator is lightened in weight, cost of the heat radiator is reduced, and comfortableness in illumination is improved.

Description

A kind of LED bulb of screw socket

Technical field

The utility model belongs to LED technical field of lamps, relates generally to profile and the radiator structure of LED bulb.

Background technology

Conventional structure of ceiling-mounted lamp in prior art, the outside of light source has a lampshade to be covered, in lampshade mainly by ballast, the compositions such as the connector that installation fluorescent tube is used and fluorescent tube, the major defect of the lamp affixed to the ceiling of this structure is install and keep in repair extremely inconvenient, and radiating effect is poor, greatly affected the life-span of fluorescent tube, and waste energy, do not meet the demand that China builds a conservation-minded society, if Chinese Patent Application No. is ZL200620068203.5, ZL200620069762.8, three patents of ZL200620070386.4, although solved well the problem of " easy to installation and maintenance ", but still exist radiating effect poor, affect its service life, and be unfavorable for energy-conservation defect., no matter at aspects such as installation, service life, energy resource consumptions, all there is open defect in the incandescent lamp that other extensively adopts in Chinese countryside.

Along with LED bulb, particularly high-power LED bulb, all adopts LED paster light source, its LED paster density of I is large, produces heat too concentrated, to radiator, requires high, cause not only huge, heaviness but also with high costs of radiator, and LED paster density height causes again dazzle too strong, produce sense of discomfort.

Summary of the invention

In order to overcome the above-mentioned defect existing in prior art, the utility model provides a kind of LED bulb of screw socket, the LED bulb of this screw socket adopts the mode that expands paster area, heatsink transverse, has reduced weight and the cost of radiator, has improved the comfort level of illumination.

The technical scheme that the LED bulb of screw socket of the present utility model adopts is:

A kind of LED bulb of screw socket, mainly by screw socket 8, driver, metallic heat radiating plate 5, form with aluminium base 6 and the lampshade 7 of LED paster, wherein driver is comprised of drive enclosure 1, driver pcb board 3 and driver plastic partition 4 three parts, driver pcb board 3 is arranged on drive enclosure 1 inside, and is fixed by driver plastic partition 4.Drive enclosure 1 top has the external screw thread being connected with the screw-internal thread fit of screw socket 8.Driver is by four screws and metallic heat radiating plate 5, fix with aluminium base 6 spirals of LED paster, and lampshade 7 is connected with the heat radiation chassis on metallic heat radiating plate 5 by rotation.

Preferably, drive enclosure 1 inside has reinforcement or strengthens cadmium 2, with this, improves the intensity of drive enclosure 1.

Preferably, lampshade 7 adopts acrylic plastics or PS plastics to make, and screw socket 8 is lamp holders of common screw socket common bulb.

The LED bulb of the screw socket that the utility model provides is than traditional electricity-saving lamp, incandescent lamp and conventional lamp affixed to the ceiling, can directly utilize the lamp holder of existing common bulb to connect, improved the adaptability of this LED bulb, expanded its range of application, renewal, energy-conservation, the cost installed have been reduced, this LED bulb also has significant high light efficiency, long-life, low pollution, the advantage such as energy-conservation simultaneously, compare existing LED bulb, there is again the advantages such as lightweight, cost is low, dazzle is little.

accompanying drawing explanation:

Fig. 1 is the decomposing schematic representation of the LED bulb of the utility model screw socket;

Fig. 2 is the combination schematic diagram of the LED bulb of the utility model screw socket.

the specific embodiment:

Now by reference to the accompanying drawings the present invention is described further.

As shown in Figure 1, decomposing schematic representation for the LED bulb of screw socket of the present utility model, the LED bulb of this screw socket is mainly by screw socket 8, driver, metallic heat radiating plate 5, form with aluminum base PCB plate 6 and the lampshade 7 of LED paster, screw socket 8 can be the lamp holder of common screw socket common bulb, therefore this LED bulb can directly utilize the lamp holder of existing common bulb to connect, improved the adaptability of this LED bulb, expand its range of application, reduced renewal, energy-conservation, the cost installed.Wherein the driver of this LED bulb is comprised of drive enclosure 1, driver pcb board 3 and driver plastic partition 4 three parts, and driver pcb board 3 is arranged on drive enclosure 1 inside, and is fixed by driver plastic partition 4.Drive enclosure 1 top has the external screw thread being connected with the screw-internal thread fit of screw socket, and drive enclosure 1 inside has reinforcement or strengthens cadmium 2, with this, improves the intensity of drive enclosure 1.Lampshade 7 is acrylic lamp shade or PS lampshade.Drive enclosure 1 top has the external screw thread being connected with the screw-internal thread fit of screw socket.Driver is by four screws and metallic heat radiating plate 5, be closely fixedly connected with the aluminium base 6 of LED paster, lampshade 7 is connected with the heat radiation chassis on metallic heat radiating plate 5 by rotation, as shown in Figure 2, finally the internal thread of the external screw thread of driver and screw socket is screwed, be the LED bulb structure form of screw socket of the present utility model.

Prior art is and adopts the longitudinal radiating mode of aluminium section bar, and the product weight of making is large, and size is long, and light-emitting area is little.The LED SMD lamp pearl of the LED bulb of screw socket of the present utility model based on adopting large chip, and adopt the mode of metallic plate heatsink transverse, rearmounted isolation constant-flow driver, make product weight light, size is little, and light-emitting area is large, has both realized the security of use, make again to complete with less lamp body the LED light source of relatively high power, not only attractive in appearance but also durable material benefit.

Above combination most preferred embodiment is described the utility model, but the utility model is not limited to the embodiment of above announcement, and should contain the various modifications of carrying out according to essence of the present utility model, equivalent combinations.
