Problems solved by technology

However, the life of LED particles in LED lamps will decrease sharply when the temperature exceeds 66°C
In response to this problem, many high-power LED lamps have designed a heat dissipation structure, but the heat dissipation effect is not good. This is because the current high-power LED lamps use high-power single-particle LEDs in order to form a single light source, and the volume is very small. , the heat is concentrated, so it is difficult to dissipate heat, which makes the current high-power LED lamps not practical and difficult to be recognized by users

Embodiment 1

[0015] Such as figure 1 As shown (in order to better explain the principle, the power supply and housing are not shown in the figure), the LED lamp of this embodiment includes a power supply, a housing and a lampshade 1, and an LED lamp holder 2, a heat sink 3 and a reflective light are arranged in the housing. body 4, the LED lamp holder 2 is evenly distributed with many small power LED particles 5, the LED lamp holder 2 is in close contact with the radiator 3, and the LED lamp holder 2 is located between the reflector 4 and the lampshade 1, so that the LED lamp holder 2 The light emitted by the LED particles 5 is reflected by the reflector 4, and then emitted through the lampshade 1 in the form of scattering by a single light source.

[0016] Heat-conducting glue is added between the heat sink 3 and the LED lamp holder 2 to form a tightly integrated heat dissipation structure. The outer periphery of the heat sink 3 is provided with a heat sink 6 exposed to the outside of the...

Abstract

The invention aims to provide a light-emitting diode (LED) luminary with a special heat dissipation structure to ensure that heat dissipation to LED particles is good and prolong the service of the LED luminary. The LED luminary comprises a power source, a shell and a lamp cover. The LED luminary is characterized in that an LED lamp seat, a heat dissipation body and a light reflection body are arranged in the shell, a plurality of LED particles are evenly distributed on the LED lamp seat, and the LED lamp seat is tightly contacted with the heat dissipation body and arranged between the light reflection body and the lamp cover to enable light given out by an LED on the LED lamp seat to project out as a single luminous source scattering mode through the lamp cover after being reflected by the light reflection body. The LED luminary has a light illuminating mode of a traditional high-power LED lamp, is convenient to dissipate heat at the same time, ensures that the LED particles inside the LED luminary is long in service life, simple in structure, convenient to process and maintain, even in illuminating without the phenomenon of double image, can be used in highways, squares, factories, warehouses, communities and the like for illuminating, and is good in practicability.

Description

technical field [0001] The invention belongs to the technical field of lamps, and in particular relates to an LED lamp. Background technique [0002] As a green light source in the future, LED lighting has made great progress in recent years. LED lamps have the following advantages: a. Low power consumption: the energy consumption of white LEDs is only 1 / 10 of that of incandescent lamps and 1 / 4 of that of energy-saving lamps. ; b. Long service life: Under the appropriate current and voltage, the service life of LED can reach 100,000 hours; C. Environmental protection: LED is made of non-toxic materials, unlike fluorescent lamps containing mercury that will cause pollution, while LED It can also be recycled and reused. However, when the temperature of LED particles in LED lamps exceeds 66°C, their lifespan will drop sharply. In response to this problem, many high-power LED lamps have designed a heat dissipation structure, but the heat dissipation effect is not good. This is...
