Abstract

The invention discloses a light-emitting diode (LED) lighting device which comprises a lamp support, a circuit board, LED particles and a lens group. The LED particles are arranged on the circuit board, and the lens group is buckled on the lamp support upside down. The lamp support is made of metal plates through a drawing technology and is provided with a groove, the groove and the circuit board form a closely fitting structure, a radiator is disposed between the groove and the circuit board, and the LED light device dissipates heat through the lamp support. The LED lighting device does not need additional radiators, the aluminum lamp support made through the drawing technology has the same or even more excellent radiating effect than the aluminum lamp support made through a casting technology only one third to one fifth material is need using, and thus cost is reduced greatly, and the heat conductivity coefficient of drawing aluminum is high, and radiating effect is good.

Description

technical field [0001] The invention relates to the lighting field, in particular to an LED lighting device and a method for manufacturing a lamp holder in the LED lighting device. Background technique [0002] Light Emitting Diode (LED, Light Emitting Diode) is a semiconductor that can convert electrical energy into light energy. It changes the principle of incandescent lamp tungsten filament luminescence and energy-saving lamp trichrome luminescence, and uses electric field luminescence. [0003] LED lamps have the advantages of energy saving, long life, good applicability, short response time, environmental protection, gorgeous colors, and pure luminous colors. They are the development direction of the lamp industry. [0004] For existing high-power lamps such as LED street lamps, tunnel lamps, and industrial and mining lamps, the LED light source is often welded to a whole aluminum substrate, then fixed on the radiator, and then sealed into the lamp housing, thereby affe...
