The present invention can solve the problem that the heat of the LED bulb is difficult to dissipate and thus the service life of the LED bulb is impacted.

Description

LED TABLE LAMP
BACKGROUND
Technical Field
The present invention relates to the technical field of lighting fixtures, and in particular to an LED table lamp.
Related Art LED lamp is a lighting fixture adopting a high-brightness white light emitting diode as light source; due to features such as energy conservation, environmental protection, small volume, non-flickering and no influence to visual acuity, the LED lamp is widely applied to people’s studying as table lamps; an LED table lamp comprises a bulb integrated with a light emitting diode and a lamp shade enclosed outside the bulb, and aluminum cooling fins are arranged below the bulb, however, this type of LED lamp has a problem that, when the lampshade is sleeved on the bulb, the heat of the bulb is difficult to dissipate and thus the service life of the bulb is impacted.
Summary
In view of the above drawbacks in existing technologies, the present invention aims to provide an LED table lamp.
In order to achieve the above aim, the present invention adopts a technical scheme as follows.
This LED table lamp comprises a bulb integrated with a light emitting diode and a lamp shade enclosed outside the bulb, wherein the lamp shade comprises an inner shade body and an outer shade body, and a U-shaped circulating medium channel is arranged between the inner shade body and the outer shade body; the circulating medium channel forms a circulating loop with a hand warmer through a micro pump, and the bulb and the micro pump are electrically connected with a respective switch through a controller respectively.
In the above technical scheme, a more detailed technical scheme may be as follows: a heat collecting plate core is arranged in the hand warmer, a U-shaped heat collecting hose is arranged in the heat collecting plate core, an inlet end of the heat collecting hose is communicated with an outlet end of the micro pump, an inlet end of the micro pump is communicated with an outlet end of the circulating medium channel, an inlet end of the circulating medium channel is communicated with an outlet end of the heat collecting hose.
Further, the micro pump is a brushless direct-current magnetic water pump; and the circulating medium is water or oil.
By adopting the above technical scheme, the present invention has following benefits when compared with existing technologies. 1. Since the lamp shade comprises an inner shade body and an outer shade body and a U-shaped circulating medium channel is arranged between the inner shade body and the outer shade body, when the bulb generates heat, the heat can be carried away in time by the circulating medium in the lampshade U-shaped channel; the LED lamp has efficient heat dissipation and the service life is prolonged. 2. Since the circulating medium channel forms a circulating loop with the hand warmer through the micro pump, the hot circulating medium conducts heat exchange with the cold medium in the hand warmer, so that the hand warmer becomes warm; therefore, heat energy is fully used and energy is saved.
Brief Description of Drawings FIG. 1 is a structure diagram of the embodiment of the present invention. FIG. 2 is a sectional view of the part A-A of FIG. 1.
Description of Embodiments
The present invention is described below in further detail in conjunction with drawings and embodiments.
Embodiment 1
An LED table lamp shown in FIG. 1 and FIG. 2 comprises a bulb 2 integrated with a light emitting diode and a lamp shade 1 enclosed outside the bulb 2, wherein the lamp shade 1 comprises an inner shade body 11 and an outer shade body 12, and a U-shaped circulating medium channel 13 is arranged between the inner shade body 11 and the outer shade body 12; the circulating medium channel 13 forms a circulating loop with a hand warmer 4 through a brushless direct-current magnetic micro pump 3, and the circulating medium in the circulating loop is water; a heat collecting plate core is arranged in the hand warmer 4, a U-shaped heat collecting hose is arranged in the heat collecting plate core, an inlet end 4a of the heat collecting hose is communicated with an outlet end 3b of the micro pump 3, an inlet end 3a of the micro pump 3 is communicated with an outlet end 1b of the circulating medium channel 13, an inlet end 1a of the circulating medium channel 13 is communicated with an outlet end 4b of the heat collecting hose; and the bulb 2 and the micro pump 3 are electrically connected with a respective switch through a controller respectively.
When the bulb generates heat, the heat can be carried into the heat collecting hose in the hand warmer in time by the circulating medium in the lampshade U-shaped channel, and then the hot medium conducts heat exchange with the cold medium in the hand warmer, so that the hand warmer becomes warm; therefore, the LED lamp can be cooled in time and the service life is prolonged, the heat energy is fully used and energy is saved.
Embodiment 2
The circulating medium in the circulating loop is oil; the rest is the same as the Embodiment 1.
