LED lighting device

Abstract

The invention discloses an LED lighting device comprising a lamp body and a lamp box. The lamp box is internally provided with a cavity for holding the lamp body embedded in the cavity, and the lamp body is removably connected to the lamp box, and comprises LED lamps, a control circuit board and lamp cups; a plurality of LED lamps are provided, and separately fixed to the control circuit board uniformly, and the LED lamps are connected to the control circuit board electrically; the control circuit board is connected to an external power supply electrically; a plurality of lamp cups are provided, and separately cover the exteriors of the corresponding LED lamps one by one; and the bottoms of the lamp cups are fixed to the control circuit board. The LED lamps are used as light sources, and the service life of the overall device can be prolonged; the power consumption is reduced, and the lamp cups additionally arranged separately correspond to the LED lamps and play a role in focusing; the light intensity of the overall device is improved greatly, and energy waste is farthest reduced.

Description

technical field [0001] The invention belongs to the field of lamp manufacturing, in particular to an LED lighting device. Background technique [0002] Lamps play an increasingly important role in modern life. Different types of light sources, lamps with different structures, and lamps that can be applied to different occasions have been developed one after another, and are used in more and more occasions. [0003] In the traditional lighting manufacturing industry, the most common light source is halogen lamps. Halogen bulbs, referred to as halogen bulbs or halogen lamps for short, are also called tungsten-halogen bulbs and quartz bulbs, which are a variant of incandescent lamps. The principle is to inject halogen gas such as iodine or bromine into the bulb. At high temperature, the sublimated tungsten wire will react chemically with the halogen, and the cooled tungsten will re-solidify on the tungsten wire to form a balanced cycle to avoid premature breakage of the tungste...

Problems solved by technology

However, in the dual-function car light disclosed in the invention, a series of temperature control devices added to adapt to the complex use environment of the car light are too complicated, which makes the whole system cumbersome, and the illumination distance that the car light can realize is too short , the installation of the lamp body requires a high degree of matching of the external installation shell, and the lamp cannot adjust its illumination angle. For users with the above needs, this lamp has a lot of inconvenience
