Problems solved by technology

The 80% heat energy will gradually increase the temperature of the LED lamps, causing the LED light source to increase with the increase of temperature. If the heat sink cannot dissipate the heat in time, it will seriously affect the service life of the LED lamps.
The radiation method of the radiator is to radiate heat into the air. If it is not recycled, it will cause a huge waste of energy

Embodiment Construction

[0029] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0030] Such as figure 1 , figure 2 and image 3 As shown, an LED self-generating lamp includes a radiator 1 and a lampshade 5 that are fastened together. The radiator 1 is a rectangular radiator 1 formed by die-casting an aluminum profile. The heat dissipation fins are all integrated with the radiator 1. One side of the heat sink 1 is smoothed, and an aluminum substrate 2 is placed on it. An LED light source 3 is arranged on the aluminum substrate 2. The LED light source 3 is electrically connected to an LED driving circuit, and is driven to emit light. The LED driving circuit is connected to t...

Abstract

The invention discloses a self-generating LED lamp and application thereof. The self-generating LED lamp comprises a heat radiator, an LED drive circuit, thermoelectric power generating bodies and a self-generating recycle module, wherein each thermoelectric power generating body comprises a heat power generating plate and a cold power generating plate; the heat power generating plates are in contact with an aluminum substrate; the cold power generating plates are in contact with the heat radiator; after the contact, heat energy generated from luminescence of LED light sources is transferred to the hot power generating plates of the thermoelectric power generating bodies; as the cold power generating plates are in contact with the heat radiator, a Seebeck effect is generated between the hot power generating plates and the cold power generating plates of the thermoelectric power generating bodies, and an electric field is generated between the hot power generating plates and the cold power generating plates to form electromotive force; then, both the hot power generating plates and the cold power generating plates are electrically connected with the self-generating recycle module to form a loop, so as to fulfill the purpose of energy conservation; and part of the heat energy can be recovered by the thermoelectric power generating bodies, so that the heat radiating effect is excellent and the service life of the LED light sources is guaranteed. According to the main application of the self-generating LED lamp, voltage between the hot power generating plates and the cold power generating plates is utilized for operation, and power generated by the self-generating LED lamp can be widely utilized.

Description

technical field [0001] The invention relates to the technical field of LED lamps, in particular to an LED self-generating lamp and its application. Background technique [0002] With the widespread use of LED lamps, their service life has received widespread attention. The service life of LED lamps is directly related to the effect of heat dissipation. Generally, after the LED light source provided in the LED lamp is powered on, it converts electric energy into light energy. However, only 20% of the photoelectric conversion rate of the LED light source is used for light emission, and the remaining 80% is converted into heat energy. The 80% heat energy will gradually increase the temperature of the LED lamp, causing the light decay of the LED light source to increase with the increase of temperature. If the radiator cannot dissipate the heat in time, it will seriously affect the service life of the LED lamp. The radiation method of the radiator is to radiate heat into the ...
