AI Technical Summary
When traditional T-bulb LED emergency lights are powered by mains electricity, the heat generated by the LED light source causes the battery to be in an environment with excessive temperature for a long time, which affects the battery life and range. Existing technology has not been able to effectively solve this problem.
By dividing the interior of the lamp body into multiple enclosed spaces, air convection is reduced, and temperature propagation efficiency is lowered. Structures such as isolation covers and heat sinks are used to isolate the LED light source and the battery, creating a temperature difference and reducing the battery's operating temperature.
This effectively reduces the temperature at which heat enters the battery from inside the light, extending battery life and range, and improving the stability and lifespan of the emergency light.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of LED lighting equipment technology, and in particular to an LED emergency T-bulb lamp that adopts an air insulation structure to improve service life and stability. Background Technology
[0002] Emergency lights are lighting fixtures that can provide illumination for a certain period of time after a power outage to meet temporary emergency needs. They are typically used in public places such as shopping malls and hotels for emergency lighting after a fire, sudden power outage, or power outage due to maintenance, to guide trapped people to evacuate or facilitate disaster relief activities.
[0003] Currently used emergency lights are mainly self-powered and independently controlled. The normal power cord is connected to the mains power supply circuit for general lighting. Normally, the emergency light's battery is charged. When the normal mains power is cut off, the backup power supply, i.e., the battery, automatically supplies power.
[0004] Therefore, the stability of the battery, an essential component in emergency lighting, is crucial to the reliability of the emergency light. However, under normal conditions, when powered by mains electricity, the LED light source generates a significant amount of heat. Although traditional T-bulb lights can dissipate heat through their casing to maintain stable LED operation, the temperature requirements of LED light sources and batteries differ, and traditional T-bulb emergency lights do not address this issue. While in the short term, the temperature environment inside the lamp body under normal operation may not significantly affect the battery, and problems may not be apparent during drills after installation, over time, it is typically observed that the self-powered lighting time of such emergency lights is significantly shortened, and the failure rate may even increase dramatically.
[0005] The reason for this is that the operating temperature requirements of batteries are actually different from those of LED light sources. If batteries are charged and discharged in an environment that exceeds the standard temperature for a long time, it will accelerate battery aging, thereby affecting battery life and endurance. Therefore, providing a suitable temperature environment for the batteries in T-bulbs is a key link in improving the service life and operational stability of emergency lighting. Utility Model Content

Furthermore, without conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. One or more of the components shown in the figures may be necessary or not, and the relative positional relationships between the components shown in the figures can be adjusted according to actual needs.
[0036] In order to provide a suitable operating temperature environment for the battery in the T-cell, such as Figures 1 to 4 As shown, in the first embodiment of this utility model, an LED emergency T-bulb is provided, which includes: a lampshade 1, a lamp cup 2, an LED light source device 3, a battery assembly 4, and an isolation cover 5, wherein... Figure 4As shown, the LED light source device 3 is attached to the opening of the lamp cup 2 to define a closed cavity 21 inside the lamp cup 2. A connecting component is provided inside the closed cavity 21. The isolation cover 5 is housed inside the closed cavity 21 and is connected to the connecting component to create an isolation cavity 51 inside the closed cavity 21. A fixing component is provided inside the isolation cavity 51. The battery assembly 4 is housed inside the isolation cavity 51 and is connected to the fixing component to maintain a distance from the inner wall of the isolation cover 5. The lamp cover 1 is connected to the lamp cup 2 and is attached to the light emission direction of the LED light source device 3.
[0037] Specifically, in this example, the LED light source device 3 is a DOB (Driver on Board) LED light source device 3. When the driver and the LED light source are integrated on an aluminum substrate, the heat source will also be concentrated. When the T-bulb is working, the working heat of the LED light source device 3 will be conducted into the enclosed cavity 21 along with its substrate. Although some of the heat will be dissipated to the outside along with the lamp cup 2 housing, the temperature inside the enclosed cavity 21 will still increase significantly.
[0038] This temperature increase occurs partly due to heat conduction through material contact, such as from the contact surface between the lamp cup 2 and the LED light source device 3, to the inner surface of the lamp cup 2; and partly due to heat conduction through the air. In this case, the isolation cover 5 installed inside the enclosed cavity 21 of the lamp cup 2 can, on the one hand, isolate direct air conduction between the isolation cavity 51 and the enclosed cavity 21. On the other hand, in this example, to reduce heat conduction through material contact between the lamp cup 2 and the isolation cover 5, such as… Figures 3 to 4 As shown, in this example, the connecting components are preferably configured to include: a plurality of carrier members 22 and fasteners 23, wherein the carrier members 22 and fasteners 23 are all arranged on the inner wall of the enclosed cavity 21, such that the carrier members 22 can be arranged at intervals on the inner wall of the lamp cup 2. Correspondingly, the bottom of the isolation cover 5 is provided with a carrier ring 52, and a carrier wall 53 extends from the outer ring of the carrier ring 52 to define a carrier groove 54 with the carrier ring 52.
[0039] With this configuration, the lamp cup 2 can not only support the support ring 52 through the support member 22 to support the isolation cover 5, so as to minimize the heat conduction contact area between the lamp cup 2 and the isolation cover 5, but also support the support wall 53 to fasten with the buckle member 23 to fix the isolation cover 5. This reduces the heat conduction efficiency from the closed cavity 21 to the isolation cavity 51, so that the temperature inside the isolation cavity 51 is lower than that inside the closed cavity 21, thus creating a more suitable ambient temperature for the battery assembly 4 inside the isolation cavity 51.
[0040] In addition, to prevent the battery assembly 4 from contacting the isolation cover 5 and causing heat conduction, such as Figure 3As shown, the example of the fastener in this example includes: a plurality of fixing posts 24, which are evenly spaced on the wall of the lamp cup 2 in the isolation cavity 51. The battery assembly 4 is clamped by the fixing posts 24 and kept at a distance from the inner wall of the isolation cover 5, so as to avoid material contact heat conduction and further improve the heat insulation effect.
[0041] In addition, to facilitate power connection of internal components, in optional examples, such as Figure 5 As shown, the support ring 52 and support wall 53 of the isolation cover 5 are provided with at least one communicating notch 10, so that the wire can pass through the isolation cavity 51 through the notch, so that the LED light source device 3 can be electrically connected to the lamp head 25 at the tail end of the lamp cup 2 and the battery assembly 4 respectively. The battery assembly 4 can be directly electrically connected to the lamp head 25 inside the isolation cavity 51. At the same time, in order to ensure the airtightness of the isolation cavity 51, the notch 10 can be sealed with a filler (such as sealant) after the wire passes through.
[0042] Furthermore, to improve the heat dissipation effect of the T-bulb and reduce the temperature inside the enclosed cavity 21, in an optional embodiment, the LED emergency T-bulb also includes a heat sink 6, preferably made of aluminum, with openings at both ends. A barrier 26 is provided on the inner surface of the lamp cup 2. The heat sink 6 is fitted onto the inner surface of the lamp cup 2, and the barrier 26 abuts against and limits the bottom opening of the heat sink 6, thus separating it from the isolation cover 5. Simultaneously, the top opening of the heat sink 6 contacts the substrate of the LED light source device 3. This configuration improves the thermal conductivity of the heat sink 6, thereby enhancing the heat dissipation effect of the lamp and reducing the temperature inside the enclosed cavity 21. This further reduces the temperature of the isolation cavity 51, providing a more favorable ambient temperature for the battery assembly 4.
[0043] On the other hand, such as Figures 6 to 9 As shown, based on the first embodiment described above, the second embodiment of this utility model also provides an LED emergency T-bulb, which includes: a lampshade 1, a lamp cup 2, an LED light source device 3, a battery assembly 4, an insulating cover 5, a heat insulation cover 7, and a heat sink 6, wherein... Figure 8 As shown, the LED light source device 3 is attached to the opening of the lamp cup 2 to define a closed cavity 21 inside the lamp cup 2. The isolation cover 5 is housed in the closed cavity 21 and is connected to the connecting component to separate an isolation cavity 51 inside the closed cavity 21.
[0044] The heat insulation cover 7 is housed within the enclosed cavity 21 and covers the outside of the isolation cover 5, thus defining a heat insulation cavity 71 between the isolation cover 5 and the heat insulation cover 7. This heat insulation cover 7 adds another layer of thermal insulation between the isolation cavity 51 and the enclosed cavity 21. Essentially, each cavity can be cooled by about 3-5°C, and since each cavity is essentially sealed, the impact of air convection on temperature is reduced, thereby enhancing the thermal insulation effect.
[0045] Among them, such as Figures 7 to 8 As shown, the example of the connecting components includes: a carrier 22 and a fastener 23. The carrier 22 and the fastener 23 are both arranged on the inner wall of the closed cavity 21. The bottom of the isolation cover 5 is provided with a carrier ring 52. The outer ring of the carrier ring 52 extends with a carrier wall 53 to define a carrier groove 54 with the carrier ring 52. The isolation cover 5 places its carrier ring 52 on the carrier 22 in the closed cavity 21 so that the carrier wall 53 is fastened with the fastener 23 to fix the isolation cover 5. The carrier groove 54 of the isolation cover 5 is also provided with a welding post 55. The bottom of the heat insulation cover 7 is provided with a connecting ring 72. The connecting ring 72 is provided with a welding hole 73. The connecting ring 72 of the heat insulation cover 7 is placed in the carrier groove 54 of the isolation cover 5 and is welded to the welding post 55 through the welding hole 73 to form a fixed connection.
[0046] Furthermore, the heat sink 6 has openings at both ends. The inner surface of the lamp cup 2 is provided with a barrier 26. The heat sink 6 is fitted onto the inner surface of the lamp cup 2, and the barrier 26 abuts against and limits the opening surface of the bottom of the heat sink 6, thus separating it from the heat insulation cover 7. The top opening surface of the heat sink 6 contacts the substrate of the LED light source device 3. This configuration improves the thermal conductivity of the heat sink 6, thereby enhancing the heat dissipation effect of the lamp, reducing the temperature inside the sealed cavity 21, and further reducing the temperature of the isolation cavity 51, thus providing a more favorable ambient temperature for the battery assembly 4.
[0047] Furthermore, to facilitate the connection of internal components to power, at least one communicating notch 10 is provided on the support ring 52 and support wall 53 of the isolation cover 5, and on the connecting ring 72 of the heat insulation cover 7, so that the wire can pass through the isolation cavity 51 and the heat insulation cavity 71, so that the LED light source device 3 can be electrically connected to the lamp head 25 at the tail end of the lamp cup 2 and the battery assembly 4 respectively. The battery assembly 4 can be directly electrically connected to the lamp head 25 inside the isolation cavity 51. At the same time, in order to ensure the airtightness of the isolation cavity 51, the notch 10 can be sealed with a filler (such as sealant) after the wire passes through.
[0048] Furthermore, a fixing member is provided inside the isolation cavity 51, and the battery assembly 4 is housed inside the isolation cavity 51 and connected to the fixing member to maintain a distance from the inner wall of the isolation cover 5. The lamp cover 1 is connected to the lamp cup 2 and covers the light emission direction of the LED light source device 3.
[0049] To prevent the battery assembly 4 from contacting the isolation cover 5 and causing heat conduction, such as... Figure 7As shown, the example of the fastener in this example includes: a plurality of fixing posts 24, which are evenly spaced on the wall of the lamp cup 2 in the isolation cavity 51. The battery assembly 4 is clamped by the fixing posts 24 and kept at a distance from the inner wall of the isolation cover 5, so as to avoid material contact heat conduction and further improve the heat insulation effect.
[0050] By setting multiple heat insulation cavities inside the lamp cup 2, the heat conduction efficiency of the heat source can be significantly reduced, thereby weakening the conducted heat layer by layer, thus providing a suitable temperature environment for the battery assembly 4 inside the isolation cavity 51.
[0051] In addition, it should be noted that the closed cavity 21, isolation cavity 51, and heat insulation cavity 71 mentioned in the above example do not specifically refer to completely sealed and airtight, but rather to cavity structures that can significantly reduce and minimize the air convection effect between each cavity. Therefore, depending on the actual situation, there may be gaps or slightly connected parts between each cavity.
[0052] In summary, the LED emergency T-bulb provided by this utility model cleverly divides the internal space of the lamp body into multiple sealed spaces to reduce air convection, thereby reducing the efficiency of temperature propagation and creating a temperature difference between the sealed spaces to achieve heat insulation. Therefore, after multiple heat insulations, the heat from the heat source inside the lamp (such as the LED light source device 3) can be reduced from entering the cavity where the battery is located, thereby providing a suitable operating temperature environment for the battery assembly 4 in the T-bulb, thus ensuring the battery life and endurance, and improving the overall lifespan and reliability of the product.
