Embodiment Construction

[0022] join figure 1 with figure 2 As shown, specifically, in this embodiment, the LED lamp with heat dissipation and dustproof on both sides includes a heat dissipation substrate 6 and heat dissipation fins (such as heat dissipation fins 61 and 62), wherein the two sides of the heat dissipation substrate 6 The cooling fins are provided on each side. For example, the heat dissipation fins 61 are disposed on one side of the heat dissipation substrate 6 , and the heat dissipation fins 62 are disposed on the other side of the heat dissipation substrate 6 . Preferably, the bottom surface of the heat dissipation substrate 6 is a lamp bead installation surface, and the lamp bead 9 is installed on the lamp bead installation surface. Preferably, as figure 2 As shown, a reserved surface 60 is provided near the edge of the bottom surface on one side of the heat dissipation substrate, and the heat dissipation fins are not provided in the reserved surface 60, including forming the he...

Abstract

The invention provides an LED (light emitting diode) lamp fitting with two sides capable of radiating heat and resisting dust. The lamp fitting comprises a radiating base plate and radiating fins, and is characterized in that two side surfaces of the base plate are provided with the radiating fins. According to the invention, two sides of an aluminum plate are cut into the fins, the distance of a thermal loop is shortened, and the radiating effect is better. When in use, the aluminum plate is placed vertically, the technical scheme more confirms to the principle of air convection, and the flow speed of the hot air can be accelerated in the vertical direction; and the problems of bird droppings and dust covering can be solved through the radiating fins arranged vertically. According to the invention, because LEDs are installed close to the edge of the bottom surface or at the bottom part on one side surface of the aluminum plate, only a plane with smaller electroplating is required, and the process cost is lowered.

Description

technical field [0001] The invention relates to an LED lamp, in particular to an LED lamp with heat dissipation and dustproof on both sides. Background technique [0002] LED is a semiconductor that can convert electrical energy into visible light. It changes the principle of tungsten filament luminescence of incandescent lamps and the three-based toner luminescence of energy-saving lamps, and uses electric field luminescence. LED has the characteristics of long life, high luminous efficiency, no radiation and low power consumption. High-power LEDs generally have 0.5W, 1W, 3W, 5W, and there are also higher power ones, but with the increase of LED power, the heat dissipation also increases. Nowadays, most high-power LEDs are single-chip applications, and plus Great heatsink. [0003] The heat dissipation fins in the prior art are generally only arranged on one side of the heat dissipation substrate, and the other side of the heat dissipation substrate is electroplated to in...
