Abstract

The utility model discloses a high-power LED spherical lighting bulb, comprising a lamp head, a heating body, a plurality of LEDs, a lamp mask, and a control circuit; wherein, one end of the heating body is connected with the lamp head and the lamp mask, and the other end of the heating body is a cylinder; the periphery of the cylinder is correspondingly provided with a plurality of fixing surfaces used for fix the LED. The utility model is provided with a heating body in the lamp, one end of the heating body is designed into the cylinder used for enlarging the installing area of LED which is greatly increased in amount, thereby strengthening the light intensity of the bulb, being suitable for indoor lighting, and increasing heating area, which rapidly and directly emits heat into the air, ensures the LED works in the normal temperature and has long service life and high durability of the whole lamp.

Description

Great power LED Global Lighting bulb

Technical field

The utility model relates to a kind of light fixture, refers in particular to a kind of great power LED Global Lighting bulb.

Background technology

Traditional lighting all adopts osram lamp or mercury fluorescent lamp, and its shortcoming is that luminous efficiency is not high, and power consumption is big, and service life is short, and not environmental protection.

For addressing the above problem, luminous efficiency height, power consumption are few, the light emitting diode (LED) of long service life and environmental protection is widely used in light fixture, but existing LED light fixture only is widely used in the decoration field, and is not able to widespread usage at lighting field because single LEDs luminosity is little.

The applicant discloses a kind of LED lighting bulb in application number is 200620108050.2 utility application, the LED group and the control circuit that comprise base, Transparent lamp shade, LED group's mounting fixing parts, form by several LED, LED group's mounting fixing parts is formed by the some circuit boards system of enclosing, and LED group installs and is distributed on each circuit board.This technical scheme is stitched together some circuit boards, has increased the erection space of LED widely, and installable LED quantity greatly increases, thereby has strengthened the luminous intensity of bulb, and the bulb luminosity that makes like this is big, can be used as lighting and is used for room lighting.But in order to reach better radiating effect, the utility model has been done further improvement.

Summary of the invention

The utility model provides that a kind of simple in structure, brightness of illumination is big, the great power LED Global Lighting bulb of good heat dissipation effect.

A kind of great power LED Global Lighting bulb is made up of lamp holder, radiator, some LED, lampshade and control circuit, and described radiator one end connects lamp holder and lampshade, and the other end is a cylinder, and cylinder periphery correspondence is provided with the installed surface that several are used to install LED.

Described radiator is provided with some radiating ribs.

The utility model is by being provided with radiator, radiator one end is made as the erection space that cylinder is used to enlarge LED, installable LED quantity greatly increases, thereby strengthened the luminous intensity of bulb, be applicable to room lighting, also increased area of dissipation simultaneously, can directly heat be dispersed in the air rapidly, make LED to work under the normal temperature being tending towards, guaranteed its service life, thereby guaranteed the durability of whole light fixture.

Description of drawings

Fig. 1 is a cross-sectional view of the present utility model.

The specific embodiment

As shown in Figure 1, a kind of great power LED Global Lighting bulb, form by lamp holder 1, radiator 2, some LED3, lampshade 4 and control circuit, radiator 2 one ends connect lamp holder 1 and lampshade 4, this end is provided with some radiating ribs (not shown), the other end is a cylinder, and cylinder periphery correspondence is provided with several LED installed surfaces 6 that is used to install LED3.

Radiator 2 adopts the good metal of thermal conductivity to make, the one end connects lamp holder 1 and lampshade 4, the other end is set to cylinder, can enlarge the area that LED is installed widely, and more LED can be installed, strengthened the luminous intensity of bulb, simultaneously also increase area of dissipation, strengthened the radiating effect of light fixture, made LED3 to work under the normal temperature being tending towards, guarantee its service life, thereby guaranteed the durability of whole light fixture.

Control circuit is positioned in the cavity of radiator 2 one end polygon cylinders, has guaranteed the overall appearance of light fixture.
