The present invention relates to a lamp and, more particularly, to an integral type fireproof lamp for covering a thermal insulating cotton.
A conventional LED lamp comprises a radiator to provide a heat dissipation function. A first kind of radiator is mounted outside of the LED lamp. A second kind of radiator is arranged in the interior of the LED lamp. The LED lamp has a lamp body having a top face and a periphery provided with a plurality of vent holes to provide a heat radiating function. An inflatable fireproof material is arranged in the vent holes. Thus, when the flame is burned to the inflatable fireproof material during a fire accident, the inflatable fireproof material is inflated to block the vent holes so as to achieve a fireproof purpose. However, the LED lamp needs to additionally provide a radiator and an inflatable fireproof material so that the LED lamp has a higher cost of fabrication and has a shorter lifetime.
The primary objective of the present invention is to provide an integral type fireproof lamp for covering a thermal insulating cotton.
In accordance with the present invention, there is provided a fireproof lamp comprising a fireproof shade, a lamp body, an LED light board, a lens, a frame, and an LED adapter. The fireproof shade is a continuous integral impermeable fireproof metallic shell that tolerates a high temperature and has a heat radiating feature. The fireproof shade has a first hollow directed downward. The lamp body is mounted in the first hollow of the fireproof shade and has a second hollow directed downward. The LED light board is mounted in the second hollow of the lamp body and abuts an inner bottom face of the second hollow tightly and closely. The lens is mounted in the second hollow of the lamp body and covers the LED light board. The frame is made of a fireproof and heat radiating material.

The LED light board 30 is electrically connected between the positive contact and the negative contact of the circuit board 63. The high pressure bypass capacitor "Y2" has a first end connected with the negative contact of the circuit board 63 and a second end that is grounded. In such a manner, when a high pressure or static is applied on the fireproof shade 10, the high pressure or static is transmitted through the fireproof shade 10 to the high pressure bypass capacitor "Y2" and is directly shorted to the LED adapter 60 to form a circuit, so that the LED light board 30 becomes a float ground bypass, thereby preventing the LED light board 30 from being impacted by the high pressure or static. The fireproof lamp of the present invention passes tests of a high pressure of 3 KV to 4KV and a static of 6KV.
In the preferred embodiment of the present invention, capillary pores between the fireproof shade 10, the lamp body 20, the LED light board 30 and the frame 50 are filled with thermal conductive silicone (not shown) to provide a vacuum heat conduction, and to prevent the heat transfer of the metallic surface from being affected by vulcanization. A thermal radiating paint (not shown) is coated on the lamp body 20 to increase heat radiation for leading the LED light source, to enhance the heat dissipation effect and to increase the lifetime of the LED.
In the preferred embodiment of the present invention, the lens 40 is removably mounted in the second hollow 21 of the lamp body 20 and has an outer face provided with scales 41.

In operation, referring to FIGS. 7 and 8 with reference to FIGS. 1-6, 20 the fireproof lamp is mounted on a ceiling 92 which is covered by a thermal insulating cotton 91. The heat produced by the LED light board 30 is transmitted through the lamp body 20 to the fireproof shade 10. At this time, the fireproof shade 10 contacts the air to dissipate the heat from the LED light board 30, the lower end of the lamp body 20 also contacts the air to dissipate the heat from the LED light board 30, and a part of the heat from the LED light board 30 is delivered upward through the LED adapter 60 to the ambient environment. When a fire accident happens, the fireproof lamp efficiently isolates the fire source under the ceiling 92 from the thermal insulating cotton 91 above the ceiling 92 to prevent the thermal insulating cotton 91 from being burned by the fire source, thereby achieving a fireproof purpose.
Referring to FIGS. 9 and 10, the lamp body 20 is a rotary lamp 10 bracket that is rotatably mounted in the first hollow 11 of the fireproof shade 10 by screws 93. Thus, the lamp body 20 can be rotated to adjust the direction of the light.
Accordingly, the frame 50, the fireproof shade 10, the lamp body 20 and the LED light board 30 closely abut each other so that the heat produced by the LED light board 30 is quickly transmitted to the lamp body 20 and the fireproof shade 10. In addition, the lower end of the lamp body 20 transmits the heat downward, and the upper end of the fireproof shade 10 dissipates the heat quickly to decrease the temperature of the LED so that the fireproof lamp has a full open heat radiating manner to enhance the heat radiating effect. Further, the components of the fireproof lamp have a heat radiating function so that the fireproof lamp does not need to additionally provide a special radiator. Further, the fireproof lamp uses metallic material that can tolerate a high temperature (gi eater than 1300°C) to construct a closed chamber to efficiently isolates the fire source under the ceiling 92 from the thermal insulating cotton 91 above the ceiling 92 so as to prevent the fire source from passing the fireproof lamp and to prevent the thermal insulating cotton 91 from being burned by the fire 5 source, thereby achieving a fireproof purpose so that the fireproof lamp does not need to additionally provide a fireproof material. Further, the LED adapter 60 is arranged highly above the frame 50 so that the LED adapter 60 forms a heat convection space to enhance the heat radiating effect and can cover the thermal insulating cotton 91. Further, the fireproof lamp has a simplified 10 structure, has fewer parts, is assembled easily, has a lower cost and has a great heat radiating effect.
Although the invention has been explained in relation to its preferred embodiment(s) as mentioned above, it is to be understood that many other possible modifications and variations can be made without departing from the scope of the present invention. It is, therefore, contemplated that the appended claim or claims will cover such modifications and variations that fall within the true scope of the invention.
