Embodiment 1

[0026] see figure 1 As shown, the light bulb provided by this embodiment mainly includes a lamp base 101 , a heat sink 102 , a casing 103 , a heat pipe 104 , a metal lamp plate 105 , and a plurality of light emitting diodes 106 .

[0027] Wherein, the heat sink 102 can be connected to the lower end of the lamp cap 101 through threaded connection, buckle connection or fixed connection, etc., and the heat sink 102 is made of metal or non-metal material with good heat dissipation performance.

[0028] The shell 103 is arranged at the lower end of the lamp holder 101, and it can be screwed or buckled or fixed in other ways.

[0029] The condensing end of the heat pipe 104 is connected to the heat sink 102. For example, the condensing end of the heat pipe 104 can be wrapped in the center of the cooling ring 102. The heat pipe 104 is located in the cavity of the housing 103. To connect, a light emitting diode 106 is arranged on the metal lamp board 105, and the light emitting diode...

Abstract

The invention relates to the field of illuminating and discloses a light-emitting diode (LED) bulb. The LED bulb comprises a lamp cap, wherein a shell is fixed at the lower end of the lamp cap; the lower end of the lamp cap is connected with a radiating fin; the radiating fin is connected with a heat pipe; the condensation end of the heat pipe is connected with a radiating ring; the heat pipe is positioned in the cavity of the shell; a metal lamp panel is fixed at the lower end of the heat pipe; and the metal lamp panel is provided with an LED which can be electrified to emit light. Heat pipe technology is applied to the LED bulb, so that the problem of radiating is solved, integration and high power of the LED bulb are realized and the popularization of the LED bulb becomes possible.

Description

technical field [0001] The invention relates to the lighting field, in particular to an LED lighting device. Background technique [0002] Traditional lighting devices are mainly incandescent lamps and fluorescent lamps. [0003] Among them, incandescent lamps are widely used due to their low price and convenient application, but they can no longer meet people's needs because of their low luminous efficiency and high post-use costs. [0004] The luminous efficiency of fluorescent lamps has been greatly improved compared with incandescent lamps, but their service life is short, and they are gradually unable to meet people's needs. [0005] In recent years, LED has rapidly developed into a new type of lighting source due to its advantages of high efficiency and long life, but so far it has not fully entered the home lighting. There are mainly two reasons for this. One is that the industry standard is not yet complete, there are many types of products on the market, and it re...
