DETAILED DESCRIPTION

[0035] The present invention is further described in conjunction with the following examples.

[0036] Depend on Figures 1 to 7 It can be seen that the ceiling lamp with air purification function described in this embodiment includes a lamp cup 9, a lamp board 91 arranged in the lamp cup 9, a panel 92 arranged on the top of the lamp cup 9, and an air purification integrated module 2 arranged at the bottom of the lamp cup 9; the surface of the panel 92 is provided with a combined emission head 1;

[0037] The combined emitter head 1 includes a housing 6 and a first emitter 41 disposed in the housing 6; a negative ion purification module is disposed in the air purification integrated module 2; the first emitter 41 is connected to a first high voltage line 51; the negative ion purification module is connected to the first high voltage line 51; the housing 6 is provided with a first emission hole 61; the height of the end of the first emitter 41 is lower than the height of the first emission hole 61. The first emission hole 61 is a trumpet-shaped tube groove, the emitter head of the first emitter 41 passes through the trumpet-shaped tube groove, and the carbon fiber emission tip releases negative ion purification substances into the air through the tube groove.

[0038] Specifically, the ceiling lamp with air purification function described in this embodiment is provided with a first emitter 41 and a negative ion purification module, so that the end of the first emitter 41 emits negative ions in the housing 6 to purify dust particles in the air. Since the height of the end of the first emitter 41 is lower than the height of the first emission hole 61, the angle formed by the geometric edge line of the end of the first emitter head and the first emission hole 61 is the negative ion emission angle, which is less than 180 degrees. This design allows negative ions to enter the air and collide forward in Brownian motion, such as Figure 6 As shown, it can effectively reduce the horizontal movement of negative ions toward the ceiling lamp, thereby avoiding the black wall phenomenon caused by dust accumulation on the surface area of ​​the ceiling lamp and nearby walls due to static electricity.

[0039] In the ceiling lamp with air purification function described in this embodiment, the air purification integrated module 2 is provided with an ozone purification module and a plasma purification module;

[0040] The combined transmitter head 1 further includes a second transmitter 42 and a third transmitter 43 both disposed in the housing 6;

[0041] The second emitter 42 and the third emitter 43 are connected to the second high voltage line 52 and the third high voltage line 53 respectively; the housing 6 is provided with a second emitting hole 62; the second emitter 42 is provided with an opening 44; the opening 44 is provided at the second emitting hole 62; the emitting tip of the third emitter 43 is provided at the opening 44;

[0042] The second high voltage line 52 and the third high voltage line 53 are respectively connected to the output end of the ozone purification module; the first high voltage line 51 is connected to the negative output end of the negative ion purification module; the first high voltage line 51 and the third high voltage line 53 are respectively connected to the output end of the plasma purification module.

[0043] Specifically, the second emitter 42 and the third emitter 43 of the present embodiment are connected to the high-voltage output end of the ozone purification module in the air purification integrated module 2 through the second high-voltage line 52 and the third high-voltage line 53, respectively, so that the tip of the third emitter 43 performs high-voltage corona discharge on the circular hole of the opening portion 44 of the second emitter 42, generates ozone substance and releases it into the air through the second emission hole 62 of the outer shell 6 to disinfect and sterilize the air.

[0044] In addition, the first high-voltage line 51 and the third high-voltage line 53 are also connected to the positive high-voltage output terminal and the negative high-voltage output terminal of the plasma purification module respectively, so that the first emitter 41 and the third emitter 43 emit plasma purification substances into the air to remove odors in the air. The combined emitter head 1 of this embodiment has a simple component structure and high versatility. Different purification modules can share emitters, which can reduce the number of high-voltage lines output by the combined module, improve the comprehensive air purification efficiency, and is easy to install and reduce costs.

[0045] In the ceiling lamp with air purification function described in this embodiment, the axis of the circular hole of the opening portion 44 coincides with the axis of the circular hole of the second emitting hole 62; the emitting tip of the third emitter 43 is arranged on the axis of the circular hole of the opening portion 44; the above arrangement enables the ions or ozone generated by the purification module to be effectively discharged into the air.

[0046] The first emitter 41 is connected to the first high-voltage line 51 by welding or riveting; the second emitter 42 is connected to the second high-voltage line 52 by welding or riveting; the third emitter 43 is connected to the third high-voltage line 53 by welding or riveting;

[0047] The tip angle of the third emitter 43 is less than 45 degrees.

[0048] The tip angle of the third emitter 43 is an acute angle less than 45 degrees. Figure 7 ; The setting of this angle is more conducive to the generation of corona discharge, and at the same time, it enables the generation of ozone substances with higher concentration and more forward movement power during corona discharge; the ozone substances cover a wider range in the air and have a better purification effect.

[0049] In the ceiling lamp with air purification function described in this embodiment, the air purification integrated module 2 is provided with a control module; the ozone purification module, the negative ion purification module and the plasma purification module are respectively connected to the control module;

[0050] The negative ion module in the traditional ceiling lamp with negative ion function works continuously, and negative ions are continuously released from the emission head, and a huge amount of negative ions are quickly formed on the surface of the panel 92. The huge amount of negative ions blocks the tendency of the negative ions to move forward. The negative ions diffuse to the surroundings due to Brownian motion, causing the black wall phenomenon near the surface of the ceiling lamp due to the accumulation of dust due to static adsorption. This embodiment can control the intermittent operation of the negative ion purification module by setting a control module; by controlling the power-on time of the negative ion purification module, the number of negative ions released into the air each time can be controlled. The appropriate amount of negative ions can effectively purify the air, and at the same time, the negative ions released into the air collide forward as much as possible, and will not accumulate near the surface of the downlight and diffuse to the surroundings, avoiding the black wall phenomenon caused by static electricity accumulation of dust; wherein the control module can be a single-chip microcomputer.

[0051] The air purification integrated module 2 is provided with a wireless module; the wireless module is connected to the control module;

[0052] The ceiling lamp with air purification function also includes a power module; the power module is used to supply power to the air purification integrated module 2 and the lamp board 91.

[0053] In the ceiling lamp with air purification function described in this embodiment, a partition plate 21 is provided in the air purification integrated module 2; the partition plate 21 divides the air purification integrated module 2 into a first cavity 22 and a second cavity 23; the ozone purification module, the negative ion purification module, the plasma purification module, the control module and the wireless module are encapsulated in the first cavity 22 by means of high-insulation epoxy resin; the power supply module is encapsulated in the second cavity 23 by means of high-insulation epoxy resin.

[0054] Since the negative ion purification module will generate static electricity hazards in the circuit when it is working, the negative ion purification module and the power module are respectively encapsulated in two independent cavities and connected through the power line 3. The high insulation material in the first cavity 22 limits the movement of static electricity generated by the negative ion module, which can effectively reduce the static electricity transmitted to the power module through the power line 3. The high insulation material in the second cavity 23 can further limit the movement and accumulation of static electricity, so that the accumulation and harm of static electricity can be isolated and weakened in a step-by-step manner. In this way, the harm of static electricity to the lamp board 91 can be effectively reduced, and the life of the lamp board 91 can be improved.

[0055] In this embodiment, a ceiling lamp with an air purification function is described, wherein the housing 6 comprises an upper housing 63 and a lower housing 64 detachably connected to the upper housing 63; the upper housing 63 is detachably connected to the lower housing 64 by screws, buckles or pins;

[0056] The lower shell 64 is provided with a first placement groove 71 for placing the first emitter 41 , a second placement groove 72 for placing the second emitter 42 , and a third placement groove 73 for placing the third emitter 43 ; the above arrangement facilitates fixing the first emitter 41 , the second emitter 42 , and the third emitter 43 .

[0057] The third emitter 43 is provided with a slot 81 ; the third placement groove 73 is provided with a boss 82 that matches the slot 81 ; the above arrangement can further fix the third emitter 43 .

[0058] The cross-sectional shape of the opening portion 44 is circular, square, polygonal or irregular.

[0059] In the ceiling lamp with air purification function described in this embodiment, the lamp board 91 is connected in parallel with an electrostatic release element. The life of the LED lamp beads in traditional ceiling lamps with negative ion purification function is seriously affected by the negative ion static electricity. In this design, an electrostatic release element is welded in parallel with the input circuit on the lamp board 91. When the static electricity accumulates to a value higher than the release threshold of the electrostatic release element, the surface of the element discharges to the air to release the static electricity, thereby protecting the lamp board 91 from being affected by static electricity and affecting its life.

[0060] In the ceiling lamp with air purification function described in this embodiment, the air purification integrated module 2 is fixed to the lamp board 91 and the lamp cup 9 by screws respectively; the lamp cup 9 is made of metal material. The combined emission head 1 is fixed to the panel 92 by means of buckles or screws.

[0061] In the ceiling lamp with air purification function described in this embodiment, the housing 6 is integrally formed with the panel 92 or the housing 6 is detachably connected to the panel 92. The housing 6 is slightly higher than the surface of the panel 92; further, the housing 6 can be flush with the panel 92 or lower than the panel 92.

[0062] In the ceiling lamp with air purification function described in this embodiment, a diffuser 93 is provided on the lamp panel 91 .

[0063] In the ceiling lamp with air purification function described in this embodiment, the power module can be detachably arranged in the lamp cup 9 or can be detachably arranged in the air purification integrated module 2.

[0064] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention, rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
