Semiconductor Light Emitting Diodes (LEDs) also generate heat during operation, which depends somewhat on the overall luminous efficiency. Under the action of external electric energy, electrons and holes are radiated and combined to generate electroluminescence, and light radiated near a PN junction can reach the outside (air) only through a semiconductor medium and a packaging medium of a chip (chip). By integrating the current injection efficiency, the radiant luminescence quantum efficiency, the chip external light extraction efficiency and the like, only 30-40% of input electric energy is converted into light energy finally, and the rest 60-70% of energy is mainly converted into heat energy in the form of lattice vibration generated by non-radiative recombination.

Generally, whether the LED lamp works stably or not, the quality is good or bad, the LED lamp is crucial to heat dissipation of a lamp body, and natural heat dissipation is often adopted for heat dissipation of high-brightness LED lamps in the market, so that the effect is not ideal. An LED lamp manufactured by an LED light source consists of an LED, a heat dissipation structure, a driver and a lens, so that heat dissipation is also an important part, and if the LED cannot dissipate heat well, the service life of the LED can be influenced.

Referring to fig. 1, the present embodiment provides a heat sink 100, which includes a connecting base 110 and a connecting rod 120 connected to each other, wherein the connecting base 110 is connected to an end of the connecting rod 120, a plurality of heat dissipation plates 130 are disposed in parallel at intervals in a length direction of the connecting rod 120, a plurality of through holes 131 are disposed on the heat dissipation plates 130, and one side of the connecting base 110 away from the connecting rod 120 is used for mounting a light source assembly 150.

Specifically, heat generated by the operation of the light source assembly 150 is conducted out through the connecting base 110, so that the heat is conducted to the outside of the heat sink 100 through the connecting rod 120 and the heat dissipation plate 130. The diameter of the heat dissipation plate 130 is greatly reduced to reduce the space used by the heat dissipation plate 130 and reduce the overall size of the lamp. The heat dissipation plate 130 is coaxially disposed with the connection rod 120 so that heat on the connection rod 120 can be uniformly transferred to the periphery of the heat dissipation plate 130. The plurality of heat dissipation plates 130 are arranged in parallel at intervals, so that heat can flow between two adjacent heat dissipation plates 130 left and right, air circulation is accelerated, and the heat can be transferred out of the heat sink 100 from between two adjacent heat dissipation plates 130. The plurality of heat radiating plates 130 increase a contact area with air, and heat is transferred from the heat radiating plates 130 to the outside of the heat sink 100, thereby increasing heat radiating efficiency of the heat sink 100. The heat dissipation plate 130 is provided with a through hole 131 so that heat can be axially transferred along the through hole 131. The hot air may flow axially upward from the connection socket 110 along the through-hole 131, and the cold air may flow axially downward from the through-hole 131, and the heat may be rapidly dissipated by the axial convection of the cold and hot air.

When the heating power is larger, the heat dissipation requirement is increased, and the number of the heat dissipation plates 130 can be set according to the heating power. For example, when the power of the lamp is 4W, the number of the heat dissipation plates 130 may be 4, which can reduce the space for placing the heat sink 100 while ensuring the heat dissipation efficiency of the lamp. When the power of the lamp is 6W, the number of the heat dissipation plates 130 can be set to 8, so that the heat dissipation efficiency of the lamp is ensured. When the lamp power is 8W, the number of the heat dissipation plates 130 may be 14.

The embodiment of the application provides a heat sink 100, connecting seat 110 and connecting rod 120 including interconnect, one side that connecting seat 110 deviates from connecting rod 120 is used for installing light source subassembly 150, so that the heat of light source subassembly 150 can be conducted to connecting rod 120 from connecting seat 110, connecting seat 110 and connecting rod 120 end connection, interval parallel arrangement has a plurality of heating panels 130 in the length direction of connecting rod 120, in order to increase heat conduction area, make the heat can follow the clearance derivation between two adjacent heating panels 130, be provided with a plurality of through-holes 131 on the heating panel 130, so that the heat can be followed through-hole 131 axial conduction, in order to improve lamps and lanterns radiating efficiency, the life of lamps and lanterns is improved.

In one possible embodiment of the present invention, as shown in fig. 2, the through holes 131 of two adjacent heat dissipation plates 130 are on the same axis.

A plurality of through holes 131 are circumferentially arranged on the heat dissipating plate 130, so that heat can be uniformly transferred from the connecting socket 110 to the outside of the heat sink 100 through the through holes 131. The hot air uniformly flows upward from the connection socket 110, and the cold air uniformly flows toward the connection socket 110 to generate a convection of the hot air and the cold air, so that the temperature of the connection socket 110 can be uniformly lowered, and the heat is rapidly dissipated from the heat sink 100 to improve the overall heat dissipation efficiency of the heat sink 100. Wherein, the convection heat exchange refers to the heat transfer process which is generated when a fluid is in direct contact with a solid wall. In the convective heat transfer process, heat conduction and convection inside the fluid act simultaneously. Physically, it means that in a liquid or gas, the hotter part rises and the cooler part falls, circulates and blends with each other, making the temperature uniform.

In one possible embodiment of the present invention, as shown in fig. 2, the notches 132 and the through holes 131 are alternately disposed on the heat dissipation plate 130.

Specifically, the notches 132 and the through holes 131 are arranged in a staggered manner, the number of the through holes 131 and the notches 132 is increased in a limited space, and the axial convection efficiency of cold air and hot air is increased, so that the heat sink 100 can quickly dissipate heat to ensure the service life of the lamp.

In particular, thermal conductivity is the property of a substance to conduct heat. When the lamp needs a large amount of heat absorption or heat dissipation in use, a material with good heat conductivity is used. Pure metals have good thermal conductivity, with silver (about 418.6) being the most preferred, copper (about 393.5) and aluminum (about 211.9) being the second most commonly used thermally conductive metal from a cost standpoint. The materials of the connection socket 110, the connection rod 120, and the heat dissipation plate 130 are all set to aluminum. Not only improves the heat conduction efficiency of the radiator 100, but also saves certain production cost.

It is understood that the materials of the connecting base 110, the connecting rod 120 and the heat dissipating plate 130 may also be copper, further improving the heat conduction efficiency of the heat sink 100.

In one possible embodiment of the present application, as shown in fig. 1, the heat dissipation plate 130 and the connection socket 110 are both provided in a circular shape.

Specifically, the heat dissipation plate 130 and the connection seat 110 are both circular, so that when heat is conducted from the connection rod 120 to the heat dissipation plate 130, the transmission speed is uniform, and meanwhile, the through holes 131 and the notches 132 in the heat dissipation plate 130 can be uniformly arranged on the heat dissipation plate 130. To ensure the heat dissipation efficiency of the heat sink 100.
