Channelized LED (light-emitting diode) lamp

Abstract

The service life of a traditional LED (light-emitting diode) lamp can be directly affected by heat dissipation effect of chips, and accordingly a larger aluminum alloy cooling fin is arranged on the top of the LED lamp so as to reduce the temperature by air circulation. When the power of the LED lamp becomes larger, the size of the aluminum alloy cooling fin increases to dissipate the heat by air circulation. According to this arrangement, the heat dissipation effect is affected in harsh and hot climate and the cost of the larger aluminum alloy cooling fin is high. By means of utilizing diverse physical phenomena and reverse thinking, the channelized LED lamp is capable of gathering the heat in narrow channels so as to enable the heat produced rapidly to cause temperature difference and air circulation. Due to setting temperature limitation, the wind can be blown out frequently and heat dissipation effect is consistent in high-temperature regions and hot weather. The channelized LED lamp is simple and scientific in structure and the aim of natural ventilation can be achieved by the gas flue effect without the huge cooling fin. Accordingly, a large number of aluminum alloy materials can be saved, the low-cost, low-carbon, energy-saving and environment-protection effect of the channelized LED lamp can be achieved and the country and the people can benefit from the channelized LED lamp.

Description

technical field [0001] The invention belongs to the lighting industry Background technique [0002] In the previous LED lights and chip heat dissipation problem is a technical focus, if the heat dissipation is not good, it will directly affect the life of the LED street lamp, at the slightest, it will accelerate the light decay and shorten the life of the LED light, and at the worst, it will burn the chip and the LED bulb, so the upper part of the LED street light There is a large aluminum alloy die-cast heat sink to reduce the temperature. The greater the power of the LED, the larger the heat dissipation "hat". They all use the size of the aluminum alloy heat sink to dissipate heat. The rise of temperature causes air convection to dissipate heat in the air, and also uses atmospheric flow to dissipate heat. This structure affects the heat dissipation effect in harsh hot weather environments. The larger the heat sink, the higher the cost, and the smaller the shortened LED lam...
