technical field

The utility model relates to an LED heat dissipation design for full-circle light projection, in particular to a heat-conducting pipe body, a wide-surface substrate, and a hollow boss for multi-face installation of LED light-emitting units that are formed by extrusion once and can be installed with heat dissipation fins.

Background technique

As we all know, LED light bulbs have gradually replaced traditional tungsten filament heating bulbs due to their advantages of low power consumption and energy saving. However, due to their low heat resistance, the industry urgently needs to solve the problem of heat dissipation. The light-emitting unit is mainly arranged towards the front end, and the light sources are concentrated and projected in the same direction of the front end. The brightness of the surrounding light is insufficient, and the overall lighting effect is lacking. The technology is insufficient, but with the increase in the number of LED light-emitting units, the temperature will increase gradually during long-term use, resulting in damage to the LED light-emitting units. The heat dissipation problem faced by this is particularly prominent. the

Known multi-directional LED bulbs, one is a rectangular heat-conducting column and a number of heat-dissipating fins welded to one end of the heat-conducting column. The other end of the heat-conducting column is a heat-absorbing end. Each LED light-emitting unit is respectively arranged on the side and end surface of the end of the heat-absorbing end to form a multi-directional projection effect. This type of heat dissipation device cannot quickly dissipate heat because the heat-conducting column system is a solid body, nor can it be effectively wired, and the cost is high. The assembly process between the fin and the heat conduction column is unstable; the other is to use one end of the heat conduction base to plant a heat conduction component, the heat conduction base surrounds the heat sink, and the heat conduction component is stamped to form joint surfaces with different angles for LED The light-emitting units are arranged in different directions. This type of heat dissipation means will be assembled in two parts due to the heat conduction base and the heat conduction component, and the heat on the heat conduction component cannot be completely transferred to the heat conduction base, so that the heat dissipation effect will decrease. The overall processing method It is cumbersome and the production efficiency is low; the other one adopts stretch forming method to form multi-angle projection, but the formed structure cannot effectively cooperate with the cooling fins for heat dissipation, and the wall thickness of the place where the light-emitting diode is attached cannot be adjusted arbitrarily. As far as power light-emitting diodes are concerned, the heat generated is different. In order to solve the problem of heat dissipation, materials with different thicknesses can only be selected for production during processing. The preparation of production materials is cumbersome, which makes the processing more complicated, which is not conducive to production and processing, and the cost is high. the
