Problems solved by technology

[0007] However, for LED lamps with large luminous power, the heat dissipation effect of the shell and the heat conduction effect of the heat-conducting silica gel are poor and cannot meet the heat dissipation requirements, so it cannot be well realized to reduce the high temperature generated by LED lighting.
If additional cooling devices are added to the casing, it will increase the manufacturing difficulty and the cost will be higher

Abstract

The invention relates to an LED lamp with a plate type radiator. The LED lamp comprises the plate type radiator and multiple LED chips. Multiple installing positions and multiple heat dissipation pillars are arranged on the plate type radiator. Each installing position is correspondingly provided with one LED chip. The plate type radiator is a metal plate type radiator. According to the LED lamp with the plate type radiator, the LED chips are directly arranged on the plate type radiator, in this way, the structure is simple, the integrated structure is achieved, the heat dissipation effect is good, and the LED chips can meet the using requirements of a high-power LED lamp. In addition, compared with a traditional LED lamp of which an outer shell needs to be additionally provided with a heat dissipation device, the plate type radiator of the LED lamp with the plate type radiator can be directly used as the outer shell, heat conduction and heat dissipation effects are very good, the manufacturing difficulty is very low, and the cost is low.

Description

technical field [0001] The invention relates to the field of radiators for LED lamps, in particular to an LED lamp with a plate radiator. Background technique [0002] LED (Light Emitting Diode, light-emitting diode), which can directly and efficiently convert electrical energy into visible light, and has a service life of tens of thousands of hours to 100,000 hours, so it is widely used in landscape, security, special and general lighting and other fields , the market potential is immeasurable. [0003] The basic structure of the LED is a P-N junction of a semiconductor. When the current flows through the LED element, the temperature of the P-N junction will rise, and the temperature of the P-N junction area is called the junction temperature of the LED. It has a very small size, so the temperature of the LED chip is also called the junction temperature of the LED chip. [0004] LED lamps made of LED are known as the most commonly used lighting lamps for their high qualit...
