A kind of natural convection device and method for indoor LED lamp

Abstract

The invention relates to a natural convective device of an indoor LED lamp and a method of the natural convective device. An air inlet flow guide plate and an exhaust flow guide plate are additionallyarranged on two sides of an illuminating cavity. A one-way air inlet valve body is additionally mounted on the outer side the air inlet flow guide plate. An exhaust valve body is additionally mountedon the outer side the exhaust flow guide plate. Flow guide plate air inlets are formed in the bottoms of the air inlet flow guide plates. Flow guide exhaust holes are formed in the bottoms of the exhaust flow guide plates. The flow guide exhaust holes are greater than the flow guide plate air inlets. The temperature of the illuminating cavity rises, hot air resistance of the flow guide exhaust holes is little, hot air enters an exhaust cavity quickly, and the illuminating cavity is relatively vacuum temporarily. Air in an air inlet cavity quickly enters the illuminating cavity through the flow guide plate air inlets due to pressure difference, and the air inlet cavity is relatively vacuum. The one-way air inlet valve body is opened under action of atmospheric pressure, and external cold air enters the air inlet cavity in a supplement mode. The hot air continuously enters the exhaust cavity, so that air pressure increases continuously. When the pressure is greater than the atmosphericpressure, the exhaust valve body is opened, and the hot air in the exhaust cavity is discharged into the atmosphere.

Description

technical field [0001] The invention relates to a natural convection device for an indoor LED lamp and a method thereof, and belongs to the technical field of indoor LED lamp design. Background technique [0002] The Chinese meaning of LEDLightEmittingDiode (hereinafter referred to as LED) is a light-emitting diode, which is a solid-state semiconductor device that can convert electrical energy into visible light. It can directly convert electricity into light. It has small size, low power consumption, long service life and high brightness. , low heat, environmental protection, durable and so on. As the global energy crisis continues to intensify, energy conservation and environmental protection are the direction of future industrial development. The lighting industry has also shifted from traditional incandescent and fluorescent lamp technologies to the field of LED lighting technology. [0003] In 2017, the penetration rate of LED lighting applications in China reached 65...

AI Technical Summary

Problems solved by technology

1. The wall of the light-emitting cavity in the lamp body structure is a vertical structure. The light with a beam angle of 120° is refracted after irradiating the cavity wall. There are easy black edges around the diffusion plate, and the uniformity of the light-emitting surface of the overall lamp is low.
