Novel LED illuminating device

Abstract

The invention brings forward a novel LED illuminating device comprising a lampshade, a heat radiator, a light filament, an installation member, a fastener and a light source assembly. Heat radiating sheets are arranged between the lampshade and the heat radiator; a plurality of outward-opening U-shaped grooves radially distributed are formed in the end surfaces of the heat radiating sheets connected with the lampshade; the opening degree of the U-shaped grooves is gradually decreased from outside to inside; the installation member is disposed in the lampshade; the installation member is fixedly connected with the heat radiator; the fastener has a slide rail and a fixing part; the slide rail is fixed on the installation member; the light source assembly has a light source plate mounted on the bottom of the lampshade and a lens disposed in the lampshade and over the light source plate; two ends of the light source plate are provided with two electrode pins; and at least one electrode pinis in an insulated connection with the light source plate via a plastic-package connection body. The novel LED illuminating device is simply structured and easy to prepare; and an LED lamp assemblinglink is reduced, so production cost is lowered.

Description

technical field [0001] The invention belongs to the field of LED lighting, and in particular relates to an LED energy-saving lighting lamp. Background technique [0002] As a new light source, LED has been widely used in various lighting facilities because of its good energy-saving effect and long life. White LED is known as the fourth-generation lighting source to replace fluorescent lamps and incandescent lamps. LED has changed the principle of tungsten filament luminescence of incandescent lamps and three-based toner luminescence of fluorescent lamps. It uses electric field luminescence and has the advantages of high luminous efficiency, no radiation, long life, low power consumption and environmental protection. [0003] The basic structure of the LED is a P-N junction of a semiconductor. When the current flows through the LED element, the temperature of the P-N junction will rise, and the temperature of the P-N junction area is called the junction temperature of the LE...
