LED bulb

FIELD

The present invention relates to lighting, and more particularly, relates to a light emitting diode (LED) as a light source lamp.

Background technique

Currently, lamps and other light emitting source used in indoor lighting incandescent light bulbs or fluorescent is substantially tube-based. However, incandescent light bulbs and fluorescent lamps are relatively low optical conversion efficiency, and its heat capacity, short life, usually only about 3000 hours.

LED, as a new semiconductor light emitting device having a small size, low heat, low power consumption, long life, etc., there are some LED light source lamp. These LED luminaires are only at the periphery of the shade and a sleeve disposed directly composition, the light efficiency of the LED, and its poor heat dissipation effect, greatly shorten lamp life.

SUMMARY The present invention is to solve the technical problems that the defects of the prior art lamps, to provide a reasonable structure, high optical efficiency, good heat dissipation LED bulb.

Aspect of the present invention to solve the technical problem that is: configuration of an LED light bulb, comprising a good heat conducting properties, which form a lumen reflective cup-shaped socket, the socket is mounted within, mounted with LED LED lamp board, the socket connector in the shade of the light side of the opening, the other side of the socket mounting openings of the insulating sleeve, the insulating sleeve and base terminus.

In the present invention, an LED light bulb, the socket of the bottom and top, respectively, defines a communicating with the venthole and the lower vent hole.

In the present invention, an LED light bulb, the outer surface of the socket is provided with a plurality of heat dissipating fins.

In the present invention, an LED lamp, the LED of the lamp socket having a certain distance between the side edges of the light opening.

In the present invention, an LED lamp, the LED is a normal LED or LED power.

In the present invention, an LED lamp, the LED is a normal LED, LED lamp board below the pad is provided with thermal insulation film.

In the present invention, an LED light bulb, the socket is a socket of aluminum or an aluminum alloy socket.

In the present invention, an LED lamp, the lamp is a standard lamp.

In the LED lamp of the present invention, the insulating sheath is formed between the cap and the sealed space, a power supply mounted within the enclosed space.

Embodiment of the present invention is an LED light bulb, has the following advantages: Since the source of light is an LED light source, thereby having a small size, low heat, and low power consumption; socket and having good thermal conductivity, and the lumen was reflective cup shape, can effectively collect light to improve the light extraction efficiency, so that with a reasonable structure, high light efficiency, long service life.

BRIEF DESCRIPTION

The accompanying drawings and the following examples further illustrate embodiments of the present invention for the drawings in which: FIG. 1 is an exploded view of an LED bulb according to the present invention; FIG. 2 is a schematic view of an LED bulb according to the present invention in an assembled state; FIG. 3 is present a schematic cross-sectional view of an assembled state of the new LED lamp.

Detailed ways

1 to 3, the present invention is one embodiment of a LED bulb comprising a lamp cover, LED 21 is mounted with the LED light source plate 2, the socket 4, the insulating sleeve 5, the base 7. The insulating sleeve 5 is mounted below the open side of the socket 4, a sealed space is formed between the base 7 and mounted within the enclosed space with a power supply 6, thereby introducing external power supplied to the LED light board 2 LED, lights mounted on the plate 21 of the LED lamp. In the present embodiment, the insulating sleeve 5 and the base 7 is fixed by a screw connection, of course, can use other types of fixing means, such as welding, bonding, snap the like.

The base 7 may be selected existing incandescent lamp bulb, e.g. E27 lamp base, or other selection criteria.

The choice of socket 4 made of a good heat conductive material, such as aluminum, aluminum alloy, copper or the like, which form a lumen reflective cup, which can collect light emitted from the LED 21, the light to increase its efficiency. Having a distance between the LED lamp board 2 is mounted in the socket 4, and the LED 21 is the light exit side of the edge of the opening of the socket 4 so that the LED can be very good 21 controls the light emitted in the required range. The light side of the socket 1 through the opening 4 can use a transparent or translucent lampshade, e.g. ethylene gram (PMMA) lamp, and other glass shade threaded connection of the globe 1, the globe. The LED 21 may be employed or normal power LED 21 LED 21. When using multiple satellites common LED 21, the LED lamp board 2 below the pad 3 is provided with thermal insulation film, which can better dissipate heat LED 21 is emitted. The LED lamp board 2 may be provided within the socket 4 by screws, adhesive or the like. In this embodiment, defines a screw hole on the insulating sheath 5, so that the screw by the LED lamp board 2 is fixed to the insulating sleeve 5, and is located within the socket 4.

To further improve the heat dissipation efficiency of the entire LED light bulb, the socket and the upper bottom 4 are available on which defines the vent hole 41 and communicating the vent hole 42, thereby forming air convection, ensure air circulation, so that the rapid heat the shed. Outer surface of the lamp holder 4 may be further provided heat dissipating fins 43, thereby increasing the heat dissipation area to improve heat dissipation efficiency.
