Embodiment Construction
[0009] exist figure 1 Among them, the radiator adopts this columnar structure, which reduces the consumption of resources. Through this columnar structure, the air can form convection and play the role of convection heat dissipation. figure 2 Among them, 3 is the air circulation hole. The LED module is installed in the downlight close to 2. When the LED downlight is working, the temperature of 2 is higher than that of other positions. Cold air enters the LED downlight through 3, and hot air passes through The outlet holes 2 and 1 are discharged to form air convection, which can effectively dissipate heat.

The invention relates to a convection-type radiating LED (light-emitting diode) down lamp, which consists of a radiator, a power supply, a lamp shell and an LED module. The effect of air convection for radiation is realized through the columnar structure of the radiator, the radiator and air flowing holes around the lamp, the convection-type radiating LED down lamp is convenient to manufacture, the cost is low and the radiating effect is good.
Description
Technical field [0001] The invention relates to a lamp, more specifically, an LED downlight with convection heat dissipation. Background technique [0002] At present, the light source part of the LED downlight generates a lot of heat, and a large radiator is needed to meet the heat dissipation requirements of the lamp, which will cause a great waste of non-renewable resources in society. Contents of the invention [0003] In order to more reasonably solve the heat dissipation problem of LED downlights, reduce resource consumption and reduce social costs. The radiator of the present invention adopts a columnar structure, and the outer casing opens a hole at an angle of 45° upward, which can form convective heat dissipation under the working condition of the lamp. [0004] The technical solution adopted by the present invention to solve the technical problem is: open a hole at an angle of 45° upward on the shell, so as to achieve the purpose of heat dissipation and dust pr...
