LED illumination lamp

Abstract

The invention discloses an LED illumination lamp which comprises a lamp cap, a base, a connection base, a cooling module and a lampshade. The connection base, the base and the lamp cap are sequentially connected from top to bottom. A driving power source is arranged in the base. The cooling module is disposed on the upper portion of the connection base and comprises multiple cooling fins and a fan chamber, and the cooling fins are arranged along the circumference of the side edge of the connection base. The LED illumination lamp improves the lighting effect, and the illumination range and brightness are better than those of a conventional LED illumination device. Meanwhile, due to the arrangement of the cooling module, the driving power source and an LED light-emitting assembly are cooled in a separated mode, and the cooling effect is improved. Exchange between air in the lampshade and the outside is achieved through a circulating fan, heat generated due to work of the LED light-emitting assembly in the lampshade is quickly dissipated, and the service life of the lamp is prolonged. An open-circuit and overcurrent protection circuit is added, so when the lamp open-circuit and overcurrent phenomena occur in the circuit, a power circuit can be switched off in time, and the power source is protected from being burnt out.

Description

technical field [0001] The invention relates to the field of LED lamps, in particular to an LED lighting lamp. Background technique [0002] LED is a light-emitting diode, which is a semiconductor solid-state light-emitting device. It uses a solid semiconductor chip as a light-emitting material. In the semiconductor, the excess energy is released through the recombination of carriers to cause photon emission, and directly emit red, blue, green and other colored lights. LED lighting products are lighting appliances manufactured using LEDs as light sources. In the context of the current global energy shortage worries rising again, saving energy is an important issue we face. In the field of lighting, the application of LED light-emitting products is attracting the attention of the world. As a new type of green light source product, LED, It must be the development trend of lighting technology, and the 21st century will be an era of new lighting sources represented by LEDs. L...

Problems solved by technology

[0003] There is no doubt that LED products have a broad market prospect, especially in the field of lighting. If LED light sources are widely used in the field of lighting, it will be a revolution in the history of human lighting. However, due to technical constraints and other factors, they cannot be widely promoted. The long life makes the cost performance of LED products with high price much higher than that of ordinary lighting products, but the short service life or even damage of LED due to heat dissipation problems has become the main bottleneck restricting its wide application. It is generally estimated that if the junction temperature of LED is reduced by 10 °, life can be increased by 50%, it can be seen that the cooling effect is huge
