Abstract

The invention discloses an LED (light emitting diode) lamp bulb which comprises a lamp head, a power supply, a plastic support, a radiating aluminum sheet, a hollow heat conduction support, a supporting block, an LED light source substrate, a hollow screw, a light-transmittable cover and a lead wire; the light supply is placed in an inner hole of the plastic support; the plastic support is screwed in the inner hole of the lamp head; the radiating aluminum sheet is of a circular shape; the hollow heat conduction support is of a hollow cylindrical shape; the small end of the hollow heat conduction support passes through central through holes of the supporting block and the radiating aluminum sheet, and is in threaded connection with an inner hole at the bottom part of the plastic support; the LED light source substrate is connected with a large end of the hollow heat conduction support through the hollow screw; and the light-transmittable cover covers an outer edge of a radiating aluminum piece which is far away from the plastic support. The LED lamp bulb provided by the invention has the advantages of large light emitting angle, fast heat radiation and small volume, and is convenient to install.

Description

A kind of LED bulb

Technical field

The present invention relates to a kind of LED bulb.

Background technology

As everyone knows, the LED lamp is a kind of novel energy-saving light source, and present existing LED lamp heat radiation is general adopts the periphery at lamp to increase the heat dissipation problem that fin solves the LED lamp, but effect is undesirable, and the volume of whole LED lamp is also bigger.

Summary of the invention

The problem to be solved in the present invention is the deficiency that overcomes in the background technology, a kind of LED bulb is provided, this LED bulb is when adopting outside fin heat radiation, also by hollow heat conduction support heat radiation, rapid heat dissipation, increased the life-span of LED lamp, and this LED bulb employing truncated cone-shaped light source matrix, lighting angle is big, whole lamp body is long-pending little, easy for installation.

For addressing the above problem, the present invention takes following technical scheme:

LED bulb of the present invention comprises lamp holder, power supply, plastic stent, heat radiation aluminium flake, hollow heat conduction support, back-up block, led light source matrix, hollow screw, diffuser, lead.Power supply is placed in the endoporus of plastic stent, plastic stent screws in the endoporus of lamp holder, the heat radiation aluminium flake is circular, hollow heat conduction support is hollow cylindrical, the small end of hollow heat conduction support is processed with external screw thread, the big end centre bore of hollow heat conduction support is processed with internal thread, the small end of hollow heat conduction support passes back-up block, the central through hole of heat radiation aluminium flake, be threaded with the endoporus formation of plastic stent bottom, the led light source matrix is fixed together by the big end of hollow screw and hollow heat conduction support, and diffuser is buckled on the outer away from one of plastic stent heat radiation aluminum component.

The led light source matrix is garden platform shape, and the big end of larger diameter end and hollow heat conduction support is fitted.

The heat radiation aluminium flake is provided with three at least, and is separated by with back-up block between adjacent.

Lead is drawn from power supply, passes hollow heat conduction support, hollow screw is connected to the led light source matrix.

It is big that LED bulb of the present invention has a lighting angle, advantage such as rapid heat dissipation, volume are little, easy for installation.
