Abstract

A lamp comprises a lamp body, at least one alternating current light emitting diode, a container which is arranged on the lamp body and contains liquid, and a plug. The alternating current light emitting diode is connected with the lamp body. The plug is connected to the lamp body and electrically connected to the AC LED. In a lamp using ac leds, the generated heat is mostly concentrated on the chip. Compared with the conventional lamp using the dc led, the generated heat is dissipated to the chip and the external transformer. In the lamp using the alternating current light emitting diode, the generated heat is almost concentrated on the chip, and the alternating current light emitting diode directly uses the alternating current power supply to provide energy, so that a transformer and energy loss in the voltage transformation process are avoided. Thus, the heat accumulated on the chip of the ac led will be sufficient to evaporate e.g. essential oils in the container. In another embodiment, the present invention utilizes a low impedance pure water surrounding the ac led to dissipate heat therefrom. In another embodiment, the present invention utilizes a metal support frame for heat dissipation.

Description

lamps

technical field

The utility model relates to a lamp, in particular to a lamp using an AC light-emitting diode.

Background technique

Generally speaking, most of the current lamps use DC light-emitting diodes (DC LEDs) as light sources. However, since the electricity used in general people's livelihood is powered by alternating current, the lamp must also be equipped with a transformer to convert the alternating current into direct current for the direct current light-emitting diodes to perform light-emitting operation. As mentioned above, when a lamp uses alternating current to emit light, it needs to go through two energy conversions. The first energy conversion is that the transformer converts AC power into DC power, and the second energy conversion is DC light-emitting diodes convert DC power into light energy. Generally speaking, the energy conversion efficiency of the first energy conversion is low and consumes a lot of electric energy, so that the luminous efficiency of the DC LED or the lamp cannot be improved. Therefore, the first energy conversion generates more heat than the second energy conversion.

In addition, US Patent Publication No. 2002/0117376 discloses an essential oil evaporator using a DC LED as a light source. Here, the heat of the DC LED is mainly generated in the first energy conversion and distributed on the transformer, and the heat accumulated on the chip is not enough to heat or evaporate the essential oil. Therefore, in this patent, DC LEDs are only used for decoration or lighting. Essential oils are heated and evaporated with an additional heating device.

In view of this, the purpose of this utility model is to provide a lamp with a light source, which can generate enough heat to evaporate essential oil.

Therefore, the heat accumulated on the chip of the AC LED will be enough to evaporate the essential oil. In another embodiment, the present invention uses a low-impedance pure water to surround the AC LED to dissipate heat. In another embodiment, the utility model utilizes a metal support frame for heat dissipation.

first embodiment

Please refer to Fig. 1, the lamp 101 of this embodiment can be used as an essential oil evaporator, and it mainly includes a lamp body 110, an AC LED 120, a plug 130, a container 140, a heating modulation controller 150 and a Temperature overload protection circuit 160 .

The lamp body 110 has a heat conducting surface 111 .

The AC LED 120 is disposed on the lamp body 110 . In more detail, the AC LED 120 is disposed on the heat conducting surface 111 of the lamp body 110 . In a preferred embodiment, the AC LED 120 is directly disposed on the heat conducting surface 111 of the lamp body 110 .

The plug 130 is electrically connected to the AC LED 120. In this embodiment, the plug 130 is integrated with the lamp body 110, and the plug 130 is arranged on the opposite surface of the heat conducting surface 111 of the lamp body 110. In addition, the plug 130 It can be a European plug.

The container 140 is disposed on the lamp body 110, and the container 140 can contain a liquid (for example, essential oil or water). In more detail, the container 140 is made of heat-conducting material, and the container 140 has a holding cup 141 and a cup cover 142 . The holding cup 141 is arranged on the lamp body 110 to carry essential oil or water. The cup cover 142 is disposed on the holding cup 141, and the cup cover 142 is substantially transparent or translucent. It should be noted that the AC LED 120 is adjacent to the container 140 (the cup 141 ), or/and the heat conducting surface 111 of the lamp body 110 is adjacent to the container 140 (the cup 141 ).

The heating modulation controller 150 is electrically connected to the AC LED 120 . In this embodiment, the heating modulation controller 150 is located on the surface of the lamp body 110 .

The temperature overload protection circuit 160 is electrically connected between the plug 130 and the AC LED 120 .

As mentioned above, when the plug 130 of the lamp 101 is plugged into an AC power socket (not shown), the AC LED 120 will emit light and generate heat. The holding cup 141 and the essential oil therein are transparent or translucent. At this time, the light emitted by the AC LED 120 can penetrate the essential oil in the cup 141 , and the heat generated by the AC LED 120 can heat and evaporate the essential oil in the cup 141 . Compared with the DC LED, the AC LED 120 does not have a transformer. Therefore, the heat generated by the AC LED 120 is concentrated on its chip, so the heat accumulated on the chip of the AC LED 120 will be much greater than that accumulated in the DC LED. heat on the chip of the LED. Therefore, the AC LED 120 can evaporate the essential oil. However, in general, DC LED chips are not used as heating means for evaporating essential oils. In more detail, when the AC LED 120 is adjacent to the container 140 (the cup 141 ) and the container 140 is made of heat-resistant material, the heat generated by the AC LED 120 will pass through the container 140 (the cup 141 ). ) to heat and evaporate the essential oil. In another embodiment, the heating means for evaporating essential oils can be more than one AC LED. That is, a lamp 101 may optionally have multiple AC LEDs surrounding or adjacent to the container 140 (the cup 141 ) to achieve the same heating function. On the other hand, the heat conducting surface 111 of the lamp body 110 is directly abutted against the AC LED 120 . The heat conduction surface 111 is adjacent to the container 140 (the cup 141 ), in particular, the heat conduction surface 111 is connected or directly abutted against the container 140 (the cup 141 ), and the heat generated by the AC LED 120 will pass through the heat conduction surface 111 And transfer to the container 140 (container cup 141) to heat and evaporate the essential oil.

As mentioned above, since the cup cover 142 of the container 140 is substantially transparent or translucent, it is easy to know the residual amount of essential oil in the cup 141 visually, and decide whether to add essential oil to the cup 141 accordingly. .

In addition, the lamp 101 can provide different lighting or heating modes through the heating modulation controller 150 . That is, the heating modulation controller 150 can be used to control the light intensity of the AC LED 120 and the evaporation rate of the essential oil. For example, when the user wants to be in a rest state, he can heat the modulation controller 150 to reduce the light intensity of the AC LED 120 . At this time, the heat generated by the AC light-emitting diode 120 will also be reduced accordingly, so that effects such as dark light and essential oil odor can be achieved at the same time. Conversely, when the user is in the working state, he can heat the modulation controller 150 to increase the luminous intensity of the AC LED 120 . At the same time, the heat generated by the AC light-emitting diode 120 will also increase accordingly, so that the evaporation speed of the essential oil can be accelerated, thereby achieving the effect of boosting the spirit.

Furthermore, when the temperature of the essential oil in the holding cup 141 is too high, the temperature overload protection circuit 160 electrically connected between the plug 130 and the AC LED 120 will cut off the AC power supplied to the AC LED 120 to prevent the entire The lamp 101 is in danger of being damaged due to the high temperature of the essential oil.
