Radiator and light-emitting diode (LED) lighting device with radiator

Abstract

The invention discloses a radiator and a light-emitting diode (LED) lighting device with the radiator. The radiator comprises a heat-conducting substrate and a plurality of radiating columns, a plurality of through holes are mounted on the heat-conducting substrate, each radiating column is disposed on one surface of the heat-conducting substrate, and the radiating columns are separately configured. The lighting device comprises the radiator and an LED light-emitting module, the LED light-emitting module is fixed on the heat-conducting substrate, and the LED light-emitting module includes a circuit board and a plurality of LEDs which are distributed on the circuit board. Accordingly, the superficial area of heat exchange with surrounding gas can be increased, and the heat-radiating efficiency of the radiator can be improved.

Description

technical field [0001] The invention relates to a lighting device, in particular to a radiator and an LED lighting device with the radiator. Background technique [0002] In recent years, due to the vigorous development and maturity of light-emitting diode (LED) technology, and its characteristics of low energy consumption, long service life, small size and fast response, it has gradually replaced traditional lighting devices; however, the most important factor affecting the life of LED The key factor is the problem of heat accumulation, so current relevant industry insiders are doing their best to develop products such as heat sinks for LEDs. [0003] The known LED lighting device mainly includes an extruded aluminum heat sink and an LED light-emitting module. The extruded aluminum heat sink includes a base plate and a plurality of cooling fins extending upward from one end of the base plate. A strip shape, and a heat dissipation channel is formed between any two adjacent ...

AI Technical Summary

Problems solved by technology

[0004] However, the known LED lighting device still has the following problems in actual use. Since each heat dissipation fin is in the shape of a long strip, the heat dissipation surface area that can exchange heat with the surrounding air is limited, and it is more likely to be affected by the wind direction. and cause the problem of dead angle

In addition, the seat plate is a closed plate body, not only the gas on the upper and lower sides of the plate body cannot perform effective heat exchange, but also it is easy to accumulate or stick dust and dirt on the upper surface of the plate body when used in an outdoor space; In this way, it will seriously affect its heat dissipation performance.
