LED lamp

Abstract

The invention discloses an LED lamp which comprises a lampshade, a base, a plurality of LED lamp beads, a radiator, a temperature sensor and a controller. The lampshade is of a hollow two-layer hemispherical structure with an opening downwards. The base is of a disc-shaped structure which is arranged horizontally. The LED lamp beads are uniformly integrated on the upper surface of the base in an encapsulating mode. The radiator comprises a housing which includes an inner barrel and an outer barrel which are coaxial. The temperature sensor is used for detecting air temperature inside the housing. The controller is electrically connected with a driving power source, the inner barrel and the temperature sensor. The radiator is arranged under the base, so that heat in the LED lamp can be rapidly discharged in time, damage to the LED lamp caused by heating of an LED lamp holder is avoided and the service life of the LED lamp is prolonged. Meanwhile the inner wall of the lampshade is coated with a coating with high transmission of light and high haze, and therefore the LED lamp is high in luminance and uniform in light color.

Description

technical field [0001] The invention relates to the technical field of LEDs. More specifically, the present invention relates to an LED lamp. Background technique [0002] LED lamps are a novel light source that has rapidly emerged in recent years. It is the fourth-generation new light source after incandescent fluorescent lamps and high-intensity discharge lamps. Solid-state lighting based on white LEDs is a typical green lighting method. Compared with traditional light sources It has many characteristics such as energy saving, environmental protection, long life, small size, safety and reliability, and fast response speed. It represents the future of lighting technology and meets the requirements of "building a resource-saving and environment-friendly society" proposed by the current government. At present, it has been widely used in various aspects such as urban landscape decoration, traffic signals, commercial advertisements and home lighting. In recent years, with the...

Problems solved by technology

[0003] Since LED is a typical point light source, it must be converted into a surface light source with uniform illumination to exert a soft lighting effect. However, the light transmittance and haze of the lampshade used in people's daily life are not high, and there is a relatively large part of the light. Energy is lost, resulting in poor overall lighting

At the same time, long-term use of existing LED lamps tends to generate a large amount of heat, and the heat is not easy to dissipate from the LED lamp, causing the LED lamp holder to heat up. When the heat reaches a certain temperature, the LED lamp is easily damaged, affecting the service life of the LED lamp, and the use effect is poor.
