Embodiment Construction

[0014] The present invention will be described in detail below with reference to the drawings and embodiments.

[0015] figure 1 It is a schematic structural diagram of an LED bulb lamp according to an embodiment of the present invention. The LED bulb lamp includes a light-transmitting bulb shell 3 with an airflow net 1; a heat transfer tube 2 with a strip-shaped LED light-emitting tube 4 (for example, a ceramic strip light-emitting tube); the LED light-emitting tube is welded to a PCB5; a drive circuit 6, A plastic lamp housing 8 with air holes (the lamp housing 8 can also be made of other materials); and a radiator 7 .

[0016] The light-transmitting bulb shell 3, for example, can be made of glass, plastic or other composite materials through air blowing, plastic blowing or injection molding. An airflow net 1 with at least one airflow hole is installed on the light-transmitting bulb shell 3 , and further preferably, the airflow net 1 is closely connected with the heat tran...

Abstract

The invention discloses an LED bulb with an internal convection radiating structure and an LED light source device. The LED bulb comprises a drive circuit (6), a lamp housing (8), a photo-permeable bulb housing (3), a radiator (7) and a heat transmission tube (2). The radiator (7) is connected with the lamp housing, the heat transmission tube (2) is connected onto the radiator, and an LED luminescent tube (4) is mounted on the heat transmission tube. A hole is opened at the top of the photo-permeable bulb housing (3), so that the top of the heat transmission tube is connected with an air flow net (1), and air penetrates through the air flow net and flows through the interior of the heat transmission tube continuously to form an air flow (A). Further, a circle of air flow groove (B) is arranged at the position where the radiator is connected with the photo-permeable bulb housing, and at least one air flow hole (C) can be arranged on the plastic lamp housing (8). The three kinds of air flow holes of A, B and C form a convection radiating channel.

Description

technical field [0001] The invention relates to an LED light bulb, in particular to an LED light bulb with an internal convection heat dissipation structure. Background technique [0002] With the development of LED technology, LED is more and more widely used in all walks of life, and higher requirements are put forward for LED bulb lamps that replace traditional incandescent lamps. However, due to the ubiquitous 2π luminous effect of LEDs, the luminous angle of LED bulbs can only be about 160 degrees, and it is difficult to achieve the full-angle luminous effect of traditional incandescent bulbs. [0003] Someone tried to use the 4π light-emitting characteristics of the LED chip to make a 4π LED bulb lamp, but because it has no heat dissipation structure support, the LED chip has serious light decay and short life. [0004] In order to solve the heat dissipation problem, the LED bulb lamps in the prior art mainly use metal passive heat sinks with cooling fins, such as Chi...
