Abstract

The utility model relates to a temperature difference electricity generation light-emitting diode (LED) lamp, which comprises a glass outer cover, a lamp holder and an LED chip which is arranged on the lamp holder. The temperature difference electricity generation LED lamp is characterized in that a heat conduction substrate, a temperature difference electricity generation plate and an LED power supply circuit substrate are connected in sequence above the LED chip. The temperature difference electricity generation LED lamp has the beneficial effects that heat generated when the LED chip is luminous is conducted onto the temperature difference electricity generation plate to be converted into electric power, and the electric power is fed back to the LED chip through the LED power supply circuit substrate to be used as the supplement of the luminous energy of the LED chip, and thereby, the energy is saved, and the electric conversion rate is improved, and moreover, a heat sink originally arranged on the lamp holder is not needed, so that the whole LED lamp has a light body, the illumination range is wide, and the service life of the lamp is further prolonged.

Description

A kind of thermo-electric generation LED lamp

Technical field

The utility model relates to a kind of LED lamp, particularly a kind of thermo-electric generation LED lamp.

Background technology

Existing LED lamp, the electrical property conversion ratio of its power circuit can only reach 85%; Because its operating temperature can not be higher than 60 ℃, so be provided with the heat eliminating medium of making of aluminium, copper, iron etc. at LED lamp socket place, it is heat-conducting substrate, make the LED lamp socket big because of the cooling mechanism volume, weight is big, and can only accomplish 180 degree irradiating angles, and the most important thing is that heat that LED wick sheet is supervened is dispersed in the environment to be wasted when luminous, make the energy of supplying with LED wick sheet can't obtain maximum application.

Summary of the invention

The purpose of this utility model, be that a kind of thermo-electric generation LED lamp will be provided, it has increased thermo-electric generation plate in the lamp holder position, the heat energy that led chip is supervened when luminous is converted into electric energy, and feed back to the LED power circuit, the conversion ratio of its electrical property is reached more than 92%, and save the cooling mechanism of lamp holder, increase the irradiating angle and the luminous power of LED lamp, energy-saving and emission-reduction.

The utility model is achieved in that described a kind of thermo-electric generation LED lamp, and it comprises the led chip on glass outer cover, lamp socket and the lamp socket, it is characterized in that: the heat-conducting substrate that is linked in sequence above led chip, thermo-electric generation plate, LED power circuit substrate.

The beneficial effects of the utility model are, the heat that led chip is produced when luminous is converted to electric power through thermo-electric generation plate, feed back to led chip by LED power circuit substrate, energy savings, its electrical conversion ratio is reached more than 92%, and saved original heat abstractor of being located on the lamp socket, make whole LED lamp body attitude light, illumination range is wide, more prolongs lamp life.

Fig. 2 is the utility model configuration diagram.

Among the figure: 1. glass outer cover, 2. lamp socket, 3. led chip, 4. heat-conducting substrate, 5. thermo-electric generation plate, 6. LED power circuit substrate.

The specific embodiment

A kind of thermo-electric generation LED lamp described in the utility model, as shown in Figure 1, 2, it comprises the led chip 3 on glass outer cover 1, lamp socket 2 and the lamp socket, the heat-conducting substrate 4 that is linked in sequence above led chip 3, thermo-electric generation plate 5, LED power circuit substrate 6.

Operation principle of the present utility model is, also produce heat when led chip is luminous, heat is delivered to the bottom surface of thermo-electric generation plate through heat-conducting substrate, cause the bottom surface temperature to raise, produce the temperature difference with its end face, make thermo-electric generation plate produce voltage, voltage is power supply by LED power circuit substrate transfer, and power supply provides electric current to led chip and be converted into light source.

The utility model weight is low, volume is little, because of distributing of empty calory, reduces the carbon dioxide discharge capacity, and has improved the conversion ratio of electrical property, has increased light efficiency, energy-conservation environmental protection again.

Claims
