Novel LED (Light Emitting Diode) flood lamp

Abstract

The invention discloses a novel LED (Light Emitting Diode) flood lamp. The novel LED flood lamp comprises a sheet metal shell 1, an LED lamp module, a fixation device, a lampshade 8 and heat dissipation holes 9, wherein the sheet metal shell 1 is a carrier; the LED lamp module is integrated in the sheet metal shell 1 through the fixation device; the lampshade 8 is buckled on the sheet metal shell 1 through self-contained buckles; the heat dissipation holes 9 are holes in the sheet metal shell 1; the LED lamp module comprises a sunflower section bar radiator 2, a driving power supply 3, an aluminum substrate 4 and LED beads 6; the fixation device comprises a rubber mat 5 and screws 7. The driving power supply 3 in the LED lamp module is connected with the aluminum substrate 4 through a wire; the LED beads 6 are fixedly arranged on the aluminum substrate 4 and are close to the sunflower section bar radiator 2; the LED lamp module is fixed to the sunflower section bar radiator 2 after passing through the sheet metal shell 1, the rubber mat 5 and the aluminum substrate 4 through the screws 7.

Description

technical field [0001] The invention relates to a novel LED floodlight, in particular to a lamp for indoor and outdoor large-scale illumination. Background technique [0002] There are many types of LED floodlights, and there are mainly die-cast aluminum shell LED floodlights and finned heat dissipation LED floodlights on the market. The heat dissipation performance of LED floodlights with die-casting aluminum shells is poor. The main reasons are: 1. The heat resistance of die-casting aluminum is relatively large; 2. The structure of the lamps is unreasonable, and the air cannot flow through the heat sink well. Fin heat dissipation LED floodlights use heat pipes to export the heat of LED lamp beads to fin radiators. The radiator effect is better, but the cost of this radiator is high and the market coverage is small. [0003] The invention uses low-cost iron sheets to process the lamp housing, and adopts profiled heat-dissipating aluminum as the radiator of the module, whic...

Problems solved by technology

The heat dissipation performance of LED floodlights with die-casting aluminum shells is poor. The main reasons are: 1. The thermal resistance of die-casting aluminum materials is large; 2. The structure of the lamps is unreasonable, and the air cannot flow through the heat sink well.

Fin heat dissipation LED floodlights use heat pipes to export the heat of LED lamp beads to fin radiators. The radiator effect is better, but the cost of this radiator is high and the market coverage is small.
