Background
Candles are one of the most widely used lighting fixtures prior to the invention of electric lamps. After the electric lamp is popular, candles are used only in some special occasions. Along with the improvement of the living standard of people, the candle is popularized in cultural leisure life, and gradually reproduced as an ornament, and is widely applied in some traditional festival. Traditional candles are prone to air pollution during burning and have the potential hazard of causing fire. For this reason, candles are now used in most applications to replace conventional candles. These candles are used by incandescent bulbs to make candles. Because the incandescent lamp has larger power consumption, the energy-saving requirement is not met. With the advancement of technology, LEDs have been invented. The LED lamp is used for replacing an incandescent lamp to be made into a candle lamp, so that the candle lamp is small in size, more similar to the traditional candle shape, less in power consumption and more environment-friendly. However, the LED chip emits light and generates more heat, so that the candle lamp has a bad heat dissipation and affects the service life. Chinese patent publication No. CN102563432a, publication day 2012, month 07 and 11, discloses a bud bulb LED lamp. The LED lamp comprises a bulb composed of a lamp shell with a hemispherical lower part, a light-transmitting lampshade connected to the lower end of the lamp shell and with a hemispherical lower end, a light source integrated module positioned in the bulb and a driving circuit board. The lighting lamp also comprises a lampshade inner shell which is positioned in the bulb and is inverted, and the lower end surface of the lampshade inner shell is provided with a multi-pyramid frustum with a vent hole. The upper end of the lampshade inner shell is connected with the lower end of the lamp shell, and the lower end of the lampshade inner shell is propped against the inner surface of the light-transmitting lampshade, so that all conical surfaces of the lampshade inner shell are distributed in the light-transmitting lampshade, and each conical surface of the lampshade inner shell is provided with a light source hole. The lower part of the light-transmitting lampshade is provided with an air inlet which is coaxial with the vent hole on the inner shell of the lampshade and has the same shape, so that a through pneumatic convection channel is formed between the air inlet and the air outlet arranged on the lamp shell. The quantity of the light source integrated modules is the same as the quantity of the conical surfaces of the inner shell of the lampshade, each light source integrated module comprises a printed circuit board, an LED light source and a plurality of radiating fins, the LED light source and the radiating fins are respectively connected to the front surface and the rear surface of the printed circuit board, each light source integrated module is arranged on the conical surface of the inner shell of the lampshade in a mode that the LED light source is embedded in a light source hole of the inner shell of the lampshade and the radiating fins are positioned on the inner side of the conical surface, and the direction of a radiating groove formed between the radiating fins on each light source integrated module is the same as the direction of a pneumatic convection channel. According to the technical scheme, the dynamic pneumatic convection heat dissipation is used for improving the conduction heat dissipation efficiency, and the service life of the LED is prolonged. When the LED lamp is used, the holes of the light-transmitting lamp shade are provided with hot air for discharging, and dust is not easy to fall into the lamp shade through the holes. But when the LED lamp is not used, the hot air is not discharged from the holes of the light-transmitting lampshade, and dust conveniently falls into the lampshade through the holes of the light-transmitting lampshade. Dust enters the lamp shade and is adhered to the LED light source, so that the illumination brightness is reduced, and the service life of the LED lamp is influenced by corrosion of the light source.
