Fence type LED lighting device

Abstract

The invention discloses a fence type LED lighting lamp, comprising radiator units, a baffle plate, a power supply shell body and a high-power LED, the radiator units are arranged to form a fence-shaped structure according to the parallel connection mode, and the radiator units are mutually completely isolated by air; the baffle plate, the radiator units and the power supply shell body are fixed by the penetration and connection mode by using bolts and seal heat conductive bases in the radiator units; an LED driving plate is fixed in the power supply shell body, and a cover plate is fixed on the power supply shell body. The radiator units solve the embodiments of various radiation structures, the light-emitting angle can be adjusted, the light shape thereof can meet the light-matching curves of the lamps which are needed by the different places, when in different light irradiation directions, a radiation channel of the lamp is smooth, thereby being capable of preventing the accumulation of dust and maintaining the initial radiation effect. Each radiator unit is composed of the heat conductive base, a heat conductive plate, a heat transfer plate, a radiating plate and a vertical column type radiator, the radiator units are produced by using aluminum material with good heat conductivity through extrusion process, the radiator units can be cut for use, and the structure is compact, thereby being capable of meeting the high-power or other semiconductor lighting lamps, such as development street lamps, tunnel lamps, projection lamps, automotive headlights, etc.

Description

technical field [0001] The invention relates to a semiconductor lighting fixture, in particular to a fence type LED lighting fixture. Background technique [0002] Semiconductor electric light source is a kind of electric light source without filament. It is a light-emitting device that directly converts electrical energy into light energy. It is called a light-emitting diode, also known as a semiconductor lamp, and is referred to as LED in English. Semiconductor lighting is considered to be a new energy-saving light source for lighting in the 21st century. LED not only saves energy, but also has the characteristics of long life, small size, safety, environmental protection, maintenance-free, and easy control. LEDs can already replace traditional light sources in many places, especially the emergence of high-power LEDs, which has accelerated the speed at which LEDs replace traditional lighting sources, and has also made the large-area application of LEDs in indoor and outdo...

AI Technical Summary

Problems solved by technology

The lamps with flat extruded profiles are composed of many high-power LEDs. The heat is concentrated in the center of the radiator, and the heat dissipation of the high-power LEDs is uneven, which leads to light decay of the high-power LEDs in the center and shortens the luminous life.

In addition, high-power LEDs with small light-emitting angles and second
