Description

Technical Field

[0001] The utility model relates to the technical field of lighting lamps, and in particular to a double-circuit fluorescent ceramic LED emergency lamp. Background Art

[0002] Industrial and mining lamps, also known as high-bay lamps, are energy-efficient indoor LED lamps that can be widely used in industrial plants, production workshops, supermarkets, sports and entertainment venues, warehouses, etc. Traditional LED lamps use a single circuit design, that is, the power supply and control system of the lamp rely on a main circuit. This design can meet lighting needs under normal circumstances, but for industrial and mining enterprises with high light requirements, harsh working environments, and the need to provide continuous and stable lighting, this single circuit design has obvious limitations. Figure 1 As shown, the external power supply 21 of the main circuit is connected to the market power grid. When the external power supply fails suddenly, the LED light source 3 stops lighting, resulting in production suspension, which is prone to safety hazards. The usual practice is to manually connect the LED light source to the emergency power supply, which is slow; when the external power supply returns to normal, the emergency power supply is manually disconnected first, and then the external power supply is connected, resulting in the interruption of the lighting of the LED light source.

[0003] Fluorescent ceramic LED light sources have the characteristics of high light efficiency, high thermal conductivity and high stability.

[0004] Therefore, how to quickly supply power to the fluorescent ceramic LED light source with an emergency power supply when an external power supply fails, and automatically disconnect the emergency power supply when the external power supply is normal, is a technical problem that needs to be solved urgently in the art. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a dual-circuit fluorescent ceramic LED emergency lamp. When an external power supply fails, the emergency power supply quickly supplies power to the fluorescent ceramic LED light source, and when the external power supply is normally supplied, the emergency power supply is automatically disconnected.

[0006] The utility model is implemented as follows: a double-circuit fluorescent ceramic LED emergency lamp, comprising:

[0007] Light-emitting heat dissipation device and dual-circuit power supply control device;

[0008] The light-emitting heat dissipation device comprises a first fluorescent ceramic LED light source, a second fluorescent ceramic LED light source and a heat sink, wherein the first fluorescent ceramic LED light source and the second fluorescent ceramic LED light source are both fixedly arranged on the front side of the heat sink;

[0009] The dual-loop power control device includes an external power supply, an emergency power supply, a normally open contactor, and a normally closed contactor. One terminal of the first fluorescent ceramic LED light source is connected to one terminal of the external power supply through the first contact of the normally open contactor, and the other terminal of the first fluorescent ceramic LED light source is connected to the other terminal of the external power supply through the second contact of the normally open contactor. One terminal of the first fluorescent ceramic LED light source is connected to one terminal of the emergency power supply through the first contact of the normally closed contactor, and the other terminal of the first fluorescent ceramic LED light source is connected to the other terminal of the emergency power supply through the second contact of the normally closed contactor. The second fluorescent ceramic LED light source is connected in series with the coil of the normally open contactor, the coil of the normally closed contactor, and the external power supply.

[0010] Further, the light-emitting and heat-dissipating device further includes a lens, a waterproof ring, and a hexagonal retaining ring. The lens surrounds the first fluorescent ceramic LED light source and the second fluorescent ceramic LED light source. The waterproof ring is located between the lens and the radiator, and the waterproof ring is also fixedly connected to the front surface of the radiator through the hexagonal retaining ring.

[0011] Further, the light-emitting and heat-dissipating device further includes a lamp shade. The lamp shade is fixedly connected to the radiator. The radiator is located outside the lamp shade, and both the first fluorescent ceramic LED light source and the second fluorescent ceramic LED light source are located inside the lamp shade.

[0012] Further, the dual-loop power control device further includes a power supply box. The emergency power supply, the normally open contactor, and the normally closed contactor are all located inside the power supply box, and the power supply box is fixedly arranged on the back surface of the radiator.

[0013] Further, the first fluorescent ceramic LED light source is a light source with a power of 50W, and the second fluorescent ceramic LED light source is a light source with a power of 200W.

[0014] Compared with the background art, the advantages of the present utility model are as follows: The coils of the normally open contactor and the normally closed contactor of the dual-loop power control device jointly detect whether the external power supply loop is powered. When a fault occurs in the external power supply, the normally open contactor disconnects the loop between the first fluorescent ceramic LED light source and the external power supply, and the normally closed contactor connects the loop between the first fluorescent ceramic LED light source and the emergency power supply. The emergency power supply quickly supplies power to the fluorescent ceramic LED light source. When the external power supply is normally powered, the normally open contactor automatically connects the loop between the first fluorescent ceramic LED light source and the external power supply, and the normally closed contactor automatically disconnects the emergency power supply, effectively avoiding the interruption of the lighting of the lamp. At this time, the external power supply also supplies power to the second fluorescent ceramic LED light source, making the lighting light brighter and facilitating the staff to detect whether the emergency power supply is in use. The heat generated by the continuous lighting of the lamp is relatively high, and the radiator helps to improve the heat dissipation effect, better meeting the lighting needs of industrial and mining enterprises.

Detailed implementation manners

[0023] An embodiment of the present utility model provides a dual-loop fluorescent ceramic LED emergency lamp, which overcomes the disadvantages of the single-loop lamp in the background art; realizes that when the external power supply fails, the emergency power supply quickly supplies power to the fluorescent ceramic LED light source, and when the external power supply is normally powered, the emergency power supply is automatically disconnected, with fast emergency speed, avoiding the interruption of the lighting of the lamp, and having good heat dissipation technical effects.

[0024] The general idea of the technical solution of the embodiment of the present utility model is as follows:

[0025] The coils of the normally open contactor and the normally closed contactor of the dual-loop power control device jointly detect whether the loop of the external power supply is powered. When the external power supply fails, the coils of the normally open contactor and the normally closed contactor are both de-energized, the first contact and the second contact of the normally open contactor are both disconnected, thereby disconnecting the loop between the first fluorescent ceramic LED light source and the external power supply, and the first contact and the second contact of the normally closed contactor are both closed, thereby connecting the loop between the first fluorescent ceramic LED light source and the emergency power supply, and the emergency power supply quickly supplies power to the fluorescent ceramic LED light source to avoid the stop of lighting; when the external power supply is normally powered, the coils of the normally open contactor and the normally closed contactor are both energized, the first contact and the second contact of the normally open contactor are both closed, thereby automatically connecting the loop between the first fluorescent ceramic LED light source and the external power supply, and the first contact and the second contact of the normally closed contactor are both disconnected, thereby automatically disconnecting the emergency power supply, effectively avoiding the interruption of the lighting of the lamp. At this time, the external power supply also supplies power to the second fluorescent ceramic LED light source to make the lighting light brighter, facilitating the staff to detect whether the emergency power supply is in use; the heat generated by the continuous lighting of the lamp is relatively high, and the radiator helps to improve the heat dissipation effect.

[0026] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings of the specification and specific implementation manners.

[0027] Refer to Figures 1 to 6 , a preferred embodiment of the present utility model.

[0028] A dual-loop fluorescent ceramic LED emergency lighting fixture, comprising:

[0029] A light-emitting and heat-dissipating device 1 and a dual-loop power control device 2;

[0030] The light-emitting and heat-dissipating device 1 includes a first fluorescent ceramic LED light source 11, a second fluorescent ceramic LED light source 12, and a radiator 13. Both the first fluorescent ceramic LED light source 11 and the second fluorescent ceramic LED light source 12 are fixedly arranged on the front surface of the radiator 13;

[0031] The dual-loop power control device 2 includes an external power supply 21, an emergency power supply 22, a normally open contactor, and a normally closed contactor. One terminal of the first fluorescent ceramic LED light source 11 is connected to one terminal of the external power supply 21 through the first contact 23 of the normally open contactor. The other terminal of the first fluorescent ceramic LED light source 11 is connected to the other terminal of the external power supply 21 through the second contact 24 of the normally open contactor. One terminal of the first fluorescent ceramic LED light source 11 is connected to one terminal of the emergency power supply 22 through the first contact 26 of the normally closed contactor. The other terminal of the first fluorescent ceramic LED light source 11 is connected to the other terminal of the emergency power supply 22 through the second contact 27 of the normally closed contactor. The second fluorescent ceramic LED light source 12 is connected in series with the coil 25 of the normally open contactor, the coil 28 of the normally closed contactor, and the external power supply 21.

[0032] The coils 28 of the normally open contactor and the normally closed contactor of the dual-loop power control device 2 jointly detect whether the circuit of the external power supply 21 is powered. When a fault occurs in the external power supply 21, the normally open contactor disconnects the circuit between the first fluorescent ceramic LED light source 11 and the external power supply 21, and the normally closed contactor connects the circuit between the first fluorescent ceramic LED light source 11 and the emergency power supply 22. The emergency power supply 22 quickly supplies power to the fluorescent ceramic LED light source. When the external power supply 21 is normally powered, the normally open contactor automatically connects the circuit between the first fluorescent ceramic LED light source 11 and the external power supply 21, and the normally closed contactor automatically disconnects the emergency power supply 22, effectively avoiding the interruption of the lighting of the lighting fixture. At this time, the external power supply 21 also supplies power to the second fluorescent ceramic LED light source 12, making the lighting light brighter and facilitating the staff to detect whether the emergency power supply 22 is in use. The heat generated by the continuous lighting of the lighting fixture is relatively high, and the radiator 13 helps to improve the heat dissipation effect, better meeting the lighting needs of industrial and mining enterprises.

[0033] The external power supply 21 is connected to the market power grid, and the emergency power supply 22 is a storage battery. The radiator 13 is cylindrical in shape and consists of multiple heat sinks. The radiator 13 is a hollow structure; at the same time, the radiator 13 is exposed to the air, increasing the convection between the radiator 13 and the surrounding air, creating a chimney effect, with a fast heat dissipation speed and better heat dissipation effect of the radiator 13. The emergency power supply 22 is isolated from the external power supply 21 to improve safety.

[0034] The fluorescent ceramic LED light source includes an LED light-emitting chip 111, a transparent fluorescent ceramic sheet 112, and an aluminum substrate 113. The LED light-emitting chip 111 is fixedly arranged on the aluminum substrate 113, the transparent fluorescent ceramic sheet 112 covers the LED light-emitting chip 111, and the aluminum substrate 113 is fixedly arranged on the front surface of the radiator 13. The fluorescent ceramic LED light source adopts a dual-channel heat dissipation technology, that is, part of the heat generated by the LED light-emitting chip 111 is transferred to the radiator 13 through the aluminum substrate 113, and the other part is dissipated outward through the transparent fluorescent ceramic sheet 112. Since the first fluorescent ceramic LED light source 11 is in lighting during both normal power supply of the external power supply 21 and when the external power supply 21 fails, being in a continuous lighting state, more heat is generated; through the dual-channel heat dissipation technology and the radiator 13, the heat dissipation performance of the first fluorescent ceramic LED light source 11 is improved, and the service life of the first fluorescent ceramic LED light source 11 is increased.

[0035] When the external power supply 21 fails, such as when the market power grid experiences a temporary power outage, the coils 28 of both the normally open contactor and the normally closed contactor lose power. The first contact 23 and the second contact 24 of the normally open contactor both open, thus disconnecting the circuit of the first fluorescent ceramic LED light source 11 and the external power supply 21. The first contact 26 and the second contact 27 of the normally closed contactor both close, thus connecting the circuit of the first fluorescent ceramic LED light source 11 and the emergency power supply 22. The emergency power supply 22 quickly supplies power to the fluorescent ceramic LED light source to avoid the interruption of lighting. At this time, the emergency power supply 22 is separated from the external power supply 21 to prevent the emergency power supply 22 from leaking electricity from the external power supply 21; when the external power supply 21 is supplying power normally, the coils 28 of both the normally open contactor and the normally closed contactor are powered on. The first contact 23 and the second contact 24 of the normally open contactor both close, thus automatically connecting the circuit of the first fluorescent ceramic LED light source 11 and the external power supply 21. The first contact 26 and the second contact 27 of the normally closed contactor both open, thus automatically disconnecting the emergency power supply 22, effectively avoiding the interruption of lighting of the lamp. At this time, the emergency power supply 22 is separated from the external power supply 21, effectively preventing the first fluorescent ceramic LED light source 11 from short-circuiting.

[0036] The light-emitting and heat-dissipating device 1 further includes a lens 14, a waterproof ring 15 and a hexagonal retaining ring 16. The lens 14 surrounds the first fluorescent ceramic LED light source 11 and the second fluorescent ceramic LED light source 12. The waterproof ring 15 is located between the lens 14 and the radiator 13, and the waterproof ring 15 is also fixedly connected to the front surface of the radiator 13 through the hexagonal retaining ring 16. The beneficial effect of this technical solution is that the lens 14 is treated with anti-glare to ensure that the human eye is not dazzled when facing the light directly; the waterproof ring 15 plays a waterproof role and improves the service life of the fluorescent ceramic LED light source; a wire mesh is welded to the top of the hexagonal retaining ring 16 to prevent the lens 14 from cracking and falling, which may cause injury to people.

[0037] The light-emitting and heat-dissipating device 1 further includes a lamp shade 17. The lamp shade 17 is fixedly connected to the radiator 13. The radiator 13 is located outside the lamp shade 17, and both the first fluorescent ceramic LED light source 11 and the second fluorescent ceramic LED light source 12 are located inside the lamp shade 17.

[0038] The dual-circuit power control device 2 further includes a power supply box 29. The emergency power supply 22, the normally open contactor and the normally closed contactor are all located inside the power supply box 29, and the power supply box 29 is fixedly arranged on the back surface of the radiator 13.

[0039] The first fluorescent ceramic LED light source 11 is a light source with a power of 50W, and the second fluorescent ceramic LED light source 12 is a light source with a power of 200W. When the external power supply 21 supplies power normally, both the first fluorescent ceramic LED light source 11 and the second fluorescent ceramic LED light source 12 are in the lighting state, and the light emitted by the lamp is relatively bright; when a fault occurs in the external power supply 21, the first fluorescent ceramic LED light source 11 is in the lighting state, and the second fluorescent ceramic LED light source 12 stops lighting, and the light emitted by the lamp is relatively dim. Such a difference in the bright and dim light of the lamp helps the staff to detect whether the emergency power supply 22 is in use and intuitively see whether a fault has occurred in the external power supply 21.

[0040] The dual-circuit fluorescent ceramic LED emergency lamp of the present utility model has remarkable improvements in terms of stability, energy efficiency, maintenance cost, lighting quality, environmental adaptability and intelligent control by adopting a dual-circuit design, a highly efficient fluorescent ceramic LED light source and a relatively intelligent control method. These improvements enable the dual-circuit fluorescent ceramic LED emergency lamp of the present utility model to better meet the lighting needs of modern industrial and mining enterprises, ensure that the lighting is not interrupted, and thus avoid problems such as production stoppage and safety hazards caused by lighting interruption; improve production efficiency and operation safety.

[0041] Although the specific embodiments of the present utility model have been described above, those skilled in the art should understand that the specific embodiments we described are illustrative rather than used to limit the scope of the present utility model. Equivalent modifications and variations made by those skilled in the art in accordance with the spirit of the present utility model should all be covered by the scope protected by the claims of the present utility model.
