Description
Technical Field
The invention relates to an LED ceiling lamp based on lampshade conduction heat dissipation.
Background
The LED lamp is usually assembled by a plurality of LEDs on the same PCB, in order to improve the brightness and the luminous efficiency, a working mode of high brightness and large current is adopted, so that the temperature is increased, if the highest temperature of the LEDs cannot be effectively controlled, the service life of the LEDs is directly influenced, and the luminous efficiency is reduced.
The heat dissipation mode generally includes heat conduction, heat radiation, air convection and the like, relatively speaking, the cost of the air convection is low, but the air is a good heat insulation material, and the heat dissipation effect through the air is poor, therefore, the Chinese patent with the application number of 201010139375.8 discloses an LED lamp, the LED lamp comprises an LED chip, a heat dissipation base and a lampshade, the lampshade is fixed on the heat dissipation base, the LED chip is located in the lampshade, and the lampshade is filled with heat conduction gas.
The heat conduction effect is better, and the common heat dissipation method is to increase the fin etc. and its problem has the cost is higher, the structure is more complicated, the volume is bigger.
There are also combinations of heat sinks and fans, which are commonly used in very powerful light fixtures.
Disclosure of Invention
According to the defects, the invention provides the LED ceiling lamp based on the conduction and heat dissipation of the lampshade, and the heat dissipation effect is improved mainly by combining the heat dissipation of the LED by the conduction of the lampshade and the air heat dissipation, so that the temperature of the LED is reduced, and the service life of the LED is prolonged.
The technical scheme of the invention is as follows:
an LED ceiling lamp based on lamp shade conduction heat dissipation includes: the lamp holder of equipment together, top cap and columniform lamp shade, install automatically controlled board on the top cap, install a plurality of PCB boards in the lamp shade, install a plurality of LEDs on the PCB board, LED's pin is equipped with the bending segment, still include a plurality of support ring, the PCB board is fixed at the periphery of support ring, under the effect of support ring and lamp shade, the elasticity that LED's bending segment produced makes LED luminous element hug closely the inner wall of lamp shade, LED luminous element passes through the lamp shade conduction heat dissipation, lamp holder and LED are connected to automatically controlled board electricity respectively.
We know that, ordinary formula LED that cut straightly has the height in welding process, the lamp shade also can have the unevenness that we can not see, it is difficult to let all LED all with lamp shade in close contact with, however, if when elastic contact all appeared with the lamp shade inner wall in luminous element of every LED, just can greatly reduced processing requirement between them, it is difficult to have elasticity to directly install welded LED, but after the bending process, when the bending section is longer, LED has certain elasticity, control the size of support ring and lamp shade, can guarantee that the luminous element of every LED hugs closely the lamp shade inner wall, LED's luminous element passes through the lamp shade conduction heat dissipation.
In the existing lamp, when the luminous body of the LED is not in contact with the lampshade, the heat of the luminous body is transferred to the lampshade through air to dissipate heat, and obviously, the heat dissipation effect is much poorer.
The electronic control board can select the most common rectifying and filtering circuit. The LEDs among the plurality of PCB boards can be connected in series and in parallel according to the voltage of the electric control board.
Preferably, the support rings are provided with two support rings, and the two support rings are respectively arranged at the top and the bottom of the PCB.
In order to improve the heat conduction effect, transparent heat conduction silicone grease is coated between the top surface of the LED luminous body and the inner wall of the lampshade.
In order to improve the heat dissipation effect, the lampshade is made of glass. Glass is not a good heat conductor compared to metal, but is a good heat conductor compared to air.
The top cover is provided with a fixing column, and the electric control board is fixed on the fixing column.
The top surface of the luminous body of the LED is a curved surface matched with the inner wall of the lampshade.
The bending section and the PCB are in an included angle.
The included angle is 5-15 degrees.
The design of an included angle can ensure that the pins of each LED are crossed without short circuit, and the installation density of the LEDs can be improved.
The LED lamp has the advantages of simple structure, low cost, reduced LED temperature and prolonged LED service life.
