Referring to Figures 6 and 7', a bulb 300 includes a lampshade, a lamp housing 32, a lamp cap 33, a carrier bracket 34, and a plurality of light-emitting elements 35. The lampshade 31 is spherical and has a first receiving space 311. The lamp cover 31 is formed with an open end. The lamp 32 is cylindrically shaped and has a second receiving space 〇 320. A plurality of through holes 321 are defined in the lamp housing 32. In this embodiment, the through holes 321 at the two ends of the lamp housing 32 are elongated, and the intermediate through holes 321 are cylindrical. The plurality of through holes 321 are used for flowing with the outside air to facilitate heat dissipation. Of course, the number and shape of the through holes 321 are not limited to the above, and may be other shapes such as a triangle, a square, a polygon, and the like. One end of the lamp housing 32 is connected to the open end of the lamp cover 31. 〇 The lamp cap 33 is a screw base for connection to other components. Of course, the lamp cap 33 can also be of other types, such as a bayonet cap, a cap with an outgoing contact, and the like. The base 33 is connected to the open end of the lamp housing 32 remote from the lamp cover 31. The carrier bracket 34 is disposed in the first receiving space j 311 of the lamp cover 31. The carrier bracket 34 has a hemispherical surface 341 having an apex. The hemispherical surface 341 of the carrier bracket 34 is disposed opposite to the globe 31. The hemispherical surface 341 is provided with 8 201042200 a plurality of receiving grooves 343 for carrying the light-emitting elements. In the present embodiment, the apex of the hemispherical surface 341 is provided with a receiving recessed groove 3431, and the other plurality of accommodating recesses 3432 are circumferentially distributed around the accommodating recess 3431 at the apex, and the same circumference The upper receiving recess 3432 is evenly distributed. The plurality of receiving recesses 343 have a cylindrical shape, a bottom surface 3434, a side surface 3433 surrounding the bottom surface 3434, and an opening 0 opposite to the bottom surface 3434. The side surface 3433 is a reflecting surface that can be used to reflect light emitted from the light emitting element such that light emitted from the light emitting element exits from the opening of the receiving recess 343. The plurality of illuminating elements 35 are respectively disposed in the plurality of accommodating recesses 343, and the side wall 3433 of the accommodating recess 343 reflects the light irradiated thereto by the illuminating 7G member 35, so that the plurality of illuminating elements 35 are The emitted light passes through the opening of the accommodating recess 343 and penetrates through the hood 31 to exit. The light-emitting element% includes a light-emitting diode wafer and a light-emitting diode. Preferably, the bulb 30 further includes a heat dissipation module 36 and a built-in power source 37. The read heat dissipation module 36 includes a support portion 361 and a plurality of heat dissipation fins 362 that are radially arranged around the support portion 361. The support portion 361 is used to carry the carrier bracket 34. Each of the heat dissipation fins 362 has a plurality of grooves 363 spaced apart from each other in a direction perpendicular to the extending direction of the support portion 361. The plurality of grooves 363 are divided into a plurality of heat dissipation units by the 9 201042200, thereby increasing the number of the heat dissipation fins 362. air flow. Preferably, the plurality of grooves 363 of the adjacent two heat dissipating chips 362 are in one-to-one correspondence. In this embodiment, the support portion 361 is integrally formed with the plurality of heat dissipation fins 362, and is made of metal such as aluminum or copper having high heat dissipation performance. The heat dissipation module 36 is received in the second receiving space 320 of the lamp housing 32, and the groove 363 of the heat dissipation fin 362 is opposite to the plurality of through holes 321 of the lamp housing 32, so that the heat dissipation module 36 absorbs The heat is dissipated to the outside air through a plurality of through holes 321 in the casing 32, thereby improving heat dissipation efficiency. The built-in power source 37 is used to supply power to the light emitting element 35. The built-in power source 37 is disposed at one end of the heat dissipation module 36 adjacent to the lamp cap 33. Preferably, the support body 361 further has a through slot 364 for accommodating the wires to facilitate the electrical connection between the built-in power source 37 and the light emitting element 35. Since the hemispherical surface 341 of the carrier bracket 34 is provided with a plurality of receiving recesses 343 for accommodating the light-emitting elements 35, the light emitted by the light-emitting elements 35 disposed in the plurality of receiving recesses 343 as a whole is The angle of light is large. At the same time, the side surface 3433 of the accommodating recess 343 is a reflecting surface, which can reflect the light irradiated onto the illuminating element 35 to the opening of the accommodating recess 3343, thereby improving the light-emitting efficiency of the bulb 300. Further, the light distribution curve of the bulb 300 can be changed by changing the number of the light-emitting elements 35 disposed in the different accommodating recesses 343, 201042200. In addition, the heat generated by the light-emitting element 35 during operation can be transmitted to the heat-dissipating module 36 and directly transmitted to the outside air via the through hole 321 in the lamp housing 32. Therefore, the bulb 3 has good heat dissipation performance. At the same time, the bulb 3 can directly supply the light-emitting element 35 via its built-in power source 37 and is connected to the external component via the base 33, so that the bulb 300 is convenient to use.
