Abstract

To provide a light-weight LED floodlight that has a relatively simple structure and is easy to assemble without using a heat dissipation structure or a forced cooling unit of a complicated structure. It has: one or more LED units (6) assembled in the central part of the inner bottom wall (1F) of the main body (1) formed with the groove (1E), and the main body (1) is extruded by a metal material The opening of the groove (1E) is formed vertically and has a U-shaped cross section on one side. The main body (1) has one or more ventilation holes (2) formed by extrusion on the back side of the inner bottom wall (1F) of the groove (1E), parallel to the extrusion direction and open at the upper and lower ends. A region (1D) with large heat capacity is arranged between the inner bottom wall (1F) equipped with the LED unit (6) and the vent hole (2). The main body (1) has a chimney effect in which the LED unit (6) is turned on with the vertical direction of the vent hole (2) in the up-down direction, thereby transferring the heat conducted from the LED unit (6) to the The airflow rising in the air hole (2) is used for heat removal.

Description

technical field

[0001] The present invention relates to a high-intensity floodlight in which a large number of LED chips are directly mounted on a substrate as a light-emitting unit, and more particularly to an LED floodlight having a structure for efficiently dissipating heat accompanying the lighting drive of the LED. lamp. Background technique

[0002] Various lighting fixtures using LED elements (light-emitting diodes, hereinafter also simply referred to as LEDs) as light-emitting devices have been commercialized based on characteristics such as high luminance (high luminosity) and low power consumption. With regard to lighting fixtures using LEDs, they range from relatively low-intensity lighting fixtures for indoor lighting constructed by installing one or more LEDs in installation containers (light fixtures) to lighting fixtures used for night lighting at construction sites, public facilities or Large-scale floodlights for lighting stadiums and the like, and lighting...
