Abstract
The utility model discloses a radiator structure of an LED lamp, which comprises LED lamp beads and a radiator. The radiator structure is characterized in that an insulating layer and a circuit layer are arranged on the surface of the radiator, a plurality of LED lamp beads are directly welded on the radiator and connected with each other through the circuit layer, and the lamp beads can be connected in a series or/and parallel manner. The utility model serves to boost the passage for heat radiation to cause the junction temperature of LED chips to drop, thereby prolonging LED service life, decreasing demand for components, and reducing cost.
Description
Technical field
The utility model relates to technical field of lamps, particularly a kind of radiator structure of LED lamp.
Background technology
Present LED lamp pearl is when using, employing is that the lamp bead weld is connected on the substrate, substrate is stained with Heat Conduction Material and is installed on the radiator, but because the thermal conductivity factor of Heat Conduction Material is low and the electric insulation requirement of lamp pearl, the heat that causes LED lamp pearl chip exists following factor to cause thermal conductivity factor low in conductive process: 1, the insulating barrier between lamp pearl and the aluminium base; 2, the heat-conducting glue between aluminium base and the fin.LED lamp pearl chip heat can not be shed fully, and light decay quickens, and the life-span lowers, and influences the penetration and promotion of LED.
Summary of the invention
The purpose of this utility model is exactly a kind of not only simplified structure, the reduction manufacturing cost that provides for the deficiency that solves prior art, and effectively improves the radiator structure of the LED lamp of radiating efficiency.
The utility model is to adopt following technical solution to realize above-mentioned purpose: the radiator structure of this LED lamp, comprise LED lamp pearl and radiator, it is characterized in that: described spreader surface has insulating barrier and circuit layer, and some LED lamp pearls directly are welded on the radiator and by circuit layer and interconnect.
As further specifying of such scheme, described insulating barrier and circuit layer are arranged on the front of radiator, and the back side of radiator is provided with radiating fin.
Described several lamp pearls are connected on the circuit layer jointly by serial or parallel connection or connection in series-parallel.
Described LED lamp pearl is more than 2 or 2.
Described LED lamp pearl is fixed on the radiator by the mode of welding or Reflow Soldering automatically.
The middle part of described radiator and sidepiece are respectively arranged with the heat radiation hole slot.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is:
The utility model adopts LED lamp pearl directly to be welded on the radiator, reduces the bottleneck that exists in the heat dissipation channel, promotes the passage that heat distributes, and the led chip junction temperature is reduced, and promotes the LED life-span, reduces part, reduces cost.

The specific embodiment
As Fig. 1～shown in Figure 4, the radiator structure of a kind of LED lamp of the utility model, main part mainly comprises LED lamp pearl 1 and radiator 2, radiator 2 is generally rectangle, there are insulating barrier and circuit layer 3 in radiator 2 surfaces, and some LED lamp pearls 1 directly are welded on the radiator 2 and by circuit layer 3 and interconnect.Wherein, LED lamp pearl 1 can be more than 2 or 2, installation method can be welding or Reflow Soldering automatically, there is not aluminium base between lamp pearl 1 and the radiator 2, radiator 2 fronts are insulating barrier and circuit layer, the back side is radiating fin 4, at the middle part of radiator 2 and sidepiece be respectively arranged with heat radiation hole slot 5, promote the passage that heat distributes.
The utility model is not limited to the foregoing description; described radiator can also adopt other version except being set to rectangle; any those skilled in the art can do numerous modifications and variations, under the spirit that does not break away from utility model, all in the claimed scope of the utility model.
