Lamp shell with air flow diversion cooling effect

Abstract

The invention discloses a lamp shell with an air flow diversion cooling effect. The lamp shell is characterized in that the peripheric circle of the lamp shell is provided with a flow diversion member, the flow diversion member is formed by an inner concave circular arc guide plate and an outer concave circular arc edge plate, and a formed section is of an oblique hook shape; and a plurality of heat dissipation fins are arranged between an outer shell and the flow diversion members. In the invention, an upper-lower hollow-out interval space is arranged between adjacent heat dissipation fins due to the special shape of the flow diversion member, thus, the flow characteristic of the air is more fitted, thereby being beneficial to thermal diversion; the heat dissipation is not only realized through thermal radiation but also realized through accelerating air convection from bottom to top, and the heat dissipation efficiency is greatly improved; lower temperature raising can be obtained, and the temperature difference of a lamp hull and air is greatly reduced, and the service life of a lamp is prolonged;and in addition, the lamp shell provided by the invention has the advantages of simple shell structure, convenience in processing, and can easily realize scale production and has practical value.

Description

technical field [0001] The invention relates to a lamp housing structure, in particular to a lamp housing with air conduction and heat dissipation functions, and belongs to the technical field of lighting. Background technique [0002] In recent years, LED has been recognized by the society for its superior performance of high efficiency, energy saving, safety and reliability, and long life, and has been increasingly widely used. With the development of LED, the emergence of high-power LED with ultra-high brightness and white light emission has expanded the application field of LED to household lighting, urban and rural lighting projects and road lighting. Although the luminous efficiency of LED is very high, which is 2 to 2.5 times that of general high-pressure sodium lamps, a certain proportion of electrical energy will still be converted into heat energy during actual use. Moreover, high-power LED lamps are actually an application in which many single high-power LEDs are...

Problems solved by technology

In the structure of the heat dissipation system mentioned above, the heat conduction base plate in the center of the lamp pool can quickly absorb the heat generated by the LED lamp body and the circuit board, and directly radiate into the surrounding air through the heat dissipation scales on the upper surface, and the heat dissipation effect is good. However, the heat-conducting base plate outside the lamp pool cannot directly absorb the heat generated by the lamp body and the circuit board, but must conduct the absorbed heat from the lamp body through the heat-conducting base plate in the middle, so as to complete the
