Light, orange light and yellow light. Conventional light-emitting diode lamps generally include a light-emitting diode light source and a colorless and transparent light cover for covering the light-emitting diode. Therefore, the color of the light emitted by the conventional lamp depends on the color of the light-emitting diode, and the color of the light of the lamp is unchangeable. With the continuous improvement of people's living standards, people's demand for life is more and more The development trend. Sometimes, in a specific occasion, the user may want to change the color of the light of the lamp, but the color of the light of the conventional lamp cannot be changed, so that the user may use a new lamp to cause unnecessary waste. In addition, for the production of Weijia, ° due to the lack of flexible design of the light color of the luminaire, not for the market cost θ ag, ~ need to replace the light color of the luminaire, so that the conventional luminaire has a "stock risk."

The driving circuit module 40 is received in the heat sink 25 The heat radiating portion 25 is electrically connected to the LED module 30. The extending portion 23 is provided with four arc-shaped first ribs 231 inwardly at equal intervals in the circumferential direction for the lamp cover 300. Cooperate. These first ribs 231 are spaced apart from the top surface of the support portion 21. Each of the first ribs 231 is horizontally disposed and extends in the circumferential direction of the extending portion 23. An arcuate first through groove 235 is formed between the two adjacent first ribs 231 at intervals in the circumferential direction. The inner sides of the first ribs 231 are collectively located on an imaginary circumference. The base of the base 100 has a cylindrical shape, and an outer thread 101 for engaging the internal thread 253 of the heat radiating portion 25 of the lamp cup 20 is provided at the periphery of the tip end. A central portion of the bottom end of the base 100 is provided with a conductive contact 103 for electrically connecting to an external power source. The lamp cap 100 is electrically connected to the external power source and the driving circuit module 40 in the lamp body 200, thereby driving the LED module 30 to operate. The LED module 30 includes a circuit board 31 and a plurality of white light emitting diodes 33 disposed on the circuit board 31. The light-emitting diode module 30 is provided at the center of the top surface of the support portion 21 of the lamp body 200. The LED module 30 is electrically connected to the driving circuit module 40 housed in the lamp cup 20, thereby obtaining power supply through the driving circuit module 40. The light-emitting diode 33 emits white light during operation. The lamp cover 300 has a hollow hemispherical shape that is open at one end. The lampshade 300 and 099125030 Form No. Α0101 Page 5 of 14 0992043969-0 201205005 The top end of the 2-inch lamp cup is connected so that the LED module 3 is placed therein. The lampshade 300 includes a semi-spherical light transmitting portion 3qi, an annular abutting portion 303 extending horizontally inward from the bottom end edge of the light transmitting portion 301, and self-offending. An annular connecting portion 3〇5 extending vertically downward from the inside of the 卩3〇3, and four second ribs horizontally outwardly protruding from the outer side of the connecting portion 305 at the bottom end of the connecting portion 305 3 〇 7. These second ribs 3 〇 7 are provided at equal intervals along the outer circumference of the "quad connection portion 305 and are spaced apart from the abutment portion 3〇3. Each of the second ribs 307 extends in the circumferential direction of the connecting portion 305. A second through groove 308 is formed between the adjacent two second ribs 307 at intervals in the circumferential direction. The lampshade 300 is made of a material that is orange in light transmission. [0013] The outer diameter of the connecting portion 305 is equivalent to the diameter of the circumference defined by the inner side of the first convex aid 231 of the lamp body 200, and the height of the quick connecting portion 3〇5 is slightly larger than the first portion of the lamp body 200. The thickness of a rib 231. The length of the second rib 307 of the lamp cover 300 extending in the circumferential direction is not greater than the length of the first through groove 235 of the lamp body 2 沿 extending in the circumferential direction. The first rib of the lamp body 2 .. The length of the ''1; " 231 extending in the circumferential direction is not greater than the length of the second through groove 308 of the lampshade 3〇〇 extending in the circumferential direction. [0014] When the lamp cover 300 is mounted, the second rib 307 of the lamp cover 300 is aligned with the first through groove 235 at the top end of the extending portion 23 of the lamp cup 20, and the lamp cover 300 is pressed down to make the second rib of the lamp cover 300. 307 passes through the corresponding first through groove 235 and abuts the support portion 21, while the first rib 231 of the lamp cup 20 passes through the second through groove 308 between the second ribs 307, at this time, the first A rib 231 and the second rib 307 are vertically offset from each other and are offset in the circumferential direction. The lamp cover 300 is rotated to rotate the lamp cover 300 relative to the lamp cup 20, so that the second rib 307 of the lamp cover 300 is sandwiched between the lamp body. Between the first rib 231 and the top surface of the support portion 0 0 091 030 Form No. 101 0101 Page 6 / Total i4 page 0992043969-0 201205005 [0015] 00 〇 [0016] [0017] 099125030 'The first rib of the lamp body 200 The 231 is interposed between the second rib 3〇7 of the lamp cover and the abutting portion 303, so that the lamp cover 300 and the lamp body 2 are detachably coupled together. When the lamp is energized, the LED module 3 emits white light. Since the light transmitting portion 301 of the globe 300 is colored. The white light emitted by the LED module 3 passes through the lamp cover 300 to change its original color, so that the lamp presents the orange color of the lamp cover 300. In this embodiment, the white light emitting diode 33 is used in combination with the lamp shade 300 to obtain the light color of the lamp. Similarly, if you want to make the lamp emit blue or other colored lights, you only need to replace the lamp cover 300 with blue or other colored lampshade to change the light color of the lamp to blue or other colors: In addition, since the lamp cover 300 can be installed or disassembled only by rotating, it is very convenient. In a specific implementation, the light emitting diode is not limited to the white light emitting diode, and the color light emitting diode may be used with a light cover whose color is different from the light emitting color of the light emitting diode, so that the light emitting diode is obtained by the light emitting diode. Another color of light that is formed by mixing the two colors of the light and the lampshade. Since the lampshade is easy to be assembled/disassembled, the user only needs to change the light-emitting color of the lamp by replacing the lampshade, thereby reducing the unnecessary waste of re-purchasing the lamp. In addition, because the illuminating color of the luminaire is adjustable, the manufacturer can know the required luminaire by adding the illuminating diode and the lampshade according to the market demand, and the elastic design of the illuminating color of the luminaire is increased, thereby reducing the inventory risk. As stated on the wire, the invention complies with the requirements of the invention patent, and the patent application is filed according to law. The above is only a preferred embodiment of the present invention, and those who are familiar with the skill of the present invention are equivalent in the spirit of the present invention.
