The invention has the beneficial effects that: external air is introduced through the edge of the lampshade, the light source is arranged on the support frame, and after the light source heats, the heat heats the air in the support frame and the base, so that the hot air automatically rises; therefore, negative pressure is generated in the lampshade to continuously suck cold air, so that the automatic heat dissipation effect is achieved, a fan is not required to be additionally arranged, and the heat dissipation is guaranteed while the silence is kept.
Drawings
FIG. 1 is a schematic structural view of the present invention;
in the figure: 1-lampshade, 2-base, 3-ventilating pipe, 4-fixing ring, 5-reflecting layer, 10-air inlet hole, 11-intercommunicating hole, 40-support frame.
Detailed Description
The technical solution of the present invention is further described below, but the scope of the claimed invention is not limited to the described.
As shown in fig. 1, a silence exhibition ceiling lamp, including lamp shade 1, base 2, support frame 40, lamp shade 1 is half spherical structure, and base 2 is both ends open-ended tubular structure, lamp shade 1 is fixed the lower extreme of base, and in base 2 is connected, support frame 40 is arranged in the space that lamp shade 1 and base 2 enclose to with base 2 sub-unit connection, the support frame is upper and lower opening, middle inclosed toper tubular structure, is equipped with the sealing washer between support frame 40 upper portion and the base 2, and support frame 40 lower part is equipped with intercommunicating pore 11, the edge of lamp shade 1 up end is provided with a plurality of inlet ports 10.
In the use, the produced heat of LED lamp passes through solid fixed ring 4 and transmits to support frame 40 on, make the air temperature of support frame and inner chamber improve, after the air temperature, can rise naturally in ventilation pipe 3 and discharge from ventilation pipe 3 upper portion, through "chimney effect", atmospheric pressure descends in the space that makes lamp shade 1 and base 2 enclose, make outside refrigerated air enter into the space that lamp shade 1 and base 2 enclose from inlet port 10, reach the effect of taking a breath, need not the fan, the noise is less, the purpose of the silence that reaches.
The upper portion of the base 2 is provided with the ventilation pipe 3, the lower portion of the ventilation pipe 3 is connected with the base 2, the lower end of the ventilation pipe 3 is communicated with the inner cavity of the support frame 40, and air is exhausted from the ventilation pipe 3 after being heated, so that air pressure in a space enclosed by the lampshade 1 and the base 2 is reduced through a chimney effect, air cooled outside enters the space enclosed by the lampshade 1 and the base 2 from the air inlet hole 10, and the effect of air exchange is achieved.
The air inlet holes 10 are distributed on the upper end face of the lampshade 1 in an annular matrix arrangement mode, the filter screen is arranged on the air inlet holes 10, the air inlet holes 10 are located on the upper end face of the lampshade 1 in an extending mode, external air can flow through the LED lamp after entering the lampshade 1, and heat can be taken away conveniently.
The inner diameter of the vent pipe 3 is 15cm to 25cm, and the length of the vent pipe 3 is more than 35cm, so that the vent pipe 3 can discharge hot air to form a chimney effect.
