The utility model discloses a fan 70 that sets up in main lamp body 10 forms the air current, reaches the effect that reduces light source board 50 and drive plate 60 temperature through the convection current of air, the active thermal discharge that promotes light source board 50 and drive plate 60 during operation production. Meanwhile, the flow difference between the air inlet 121 and the air outlet 111 makes the fan 70 form positive pressure in the main lamp body 10 when working, that is, the air pressure inside the main lamp body 10 is greater than the air pressure outside the main lamp body 10, and the air carrying heat is discharged through the air outlet 111 and kept away from the periphery of the main lamp body 10, thereby preventing the discharged hot air from being sucked back into the main lamp body 10 from the air inlet hole to affect the heat dissipation effect.

The utility model discloses can implement different product forms such as bulb, down lamp, shot-light, the bulb is used as the example to this embodiment, as shown in fig. 1, fig. 2, fig. 3, this embodiment includes cell-shell 20, main lamp body 10, lamp holder 30, electrically conductive drawing pin 40, light source board 50, drive plate 60, fan 70, and cell-shell 20, main lamp body 10, lamp holder 30, electrically conductive drawing pin 40 assemble as an organic whole, and light source board 50, drive plate 60, fan 70 set up in main lamp body 10. The main lamp body 10 may be a heat dissipating lamp body made of a material with high thermal conductivity, for example, the sleeve 11 and the lamp holder 12 are made of a metal material, so as to improve passive heat dissipating performance as much as possible, so that heat generated by the light source board 50 and the driving board 60 during operation can be conducted to the lamp holder 12 and the sleeve 11, and dissipated outwards.

In order to realize that when the fan 70 operates, a positive pressure is formed inside the main lamp body 10, and the air inlet rate of the air inlet 121 is required to be greater than the air outlet rate of the air outlet 111, in this embodiment, the total size of the air inlet 121 is greater than the total size of the air outlet 111, and the total air inlet rate determined by all the air inlets 121 is greater than the total air outlet rate determined by all the air outlets 111; alternatively, the individual inlets 121 are all sized larger than the outlets 111 and ensure that the total inlet rate is greater than the total outlet rate. Specifically, the air outlet 111 is a plurality of thin slits arranged along the circumferential direction of the sleeve 11, and the width of the thin slits is not less than 1 mm; the air inlet 121 is formed by hollowing out one end of the lamp holder 12 facing the sleeve 11 between the upper flow guiding ribs 122. Wherein, gas outlet 111 equipartition sets up to the radiating effect in the balanced sleeve 11, and slender gas outlet 111 can obtain the faster initial velocity of giving vent to anger. The air inlet 121 may also be implemented as a number of regularly or irregularly distributed through holes, the number of which is less than the number of slits, and the size of a single through hole is several times that of a single slit.

In order to enable the fan 70 to suck enough air at the air inlet side, in the embodiment, the fan 70 is disposed at the connecting end of the sleeve 11 through the bracket 71, and after the sleeve 11 is sleeved and connected with the lamp holder 12, the light source board 50 is spaced from the fan 70. Specifically, a bracket 71 is provided at an end surface of the attachment end of the sleeve 11, and the fan 70 is fixed to the bracket 71. In a specific implementation, the driving plate 60 is disposed in the sleeve 11, the bracket 71 is mounted on a screw post 113 (the screw post 113 may be disposed in the sleeve 11 or may be integrally formed on the inner wall of the sleeve 11) in the sleeve 11 by a screw, and the fan 70 is fixed on the bracket 71 by a screw. Then, the lamp cap 30 is riveted (pre-assembled with the conductive drawing pin 40), the sleeve 11 is sleeved and connected with the lamp holder 12, the light source board 50 is arranged at the mounting end of the lamp holder 12, and the bulb 20 is mounted. In order to guarantee the installation intensity and the quick heat conduction of light source board 50, the installation end of lamp stand 12 is provided with mounting panel 123, and mounting panel 123 and lamp stand 12 be integrated into one piece's structure, and light source board 50 laminating mounting panel 123 sets up.

In order to ensure the heat dissipation of the light source board 50 and the driving board 60 at the same time, the air outlet 111 is opened at one end of the sleeve 11 close to the lamp cap 30; the air inlet 121 is opened at one end near the light source board 50. Furthermore, when the fan 70 is operated, the air flow formed inside the main lamp body 10 is introduced from a position close to the light source board 50, passes through the driving board 60, and is discharged from the air outlet 111, and can carry heat generated when the light source board 50 and the driving board 60 are operated, and be discharged to the outside.
