Description

Technical Field

[0001] This utility model relates to an LED bulb, and more particularly to an LED bulb that emits light from all angles. Background Technology

[0002] Currently, LED bulbs on the market typically use a structure consisting of a lamp cup, a lampshade, and a light source. For example, patent application number 201310134214.3 discloses an omnidirectional LED bulb. To achieve sufficient heat dissipation, the light source is usually placed in the center of the LED bulb and connected to a heat dissipation component. This provides better heat dissipation performance, improving the bulb's lifespan and safety. However, this results in a relatively small beam angle, leading to a brighter illuminated area and a darker unilluminated area, creating a noticeable spatial difference. Summary of the Invention

[0003] The purpose of this invention is to provide an omnidirectional LED bulb. It utilizes LED light-emitting components on both sides of the mounting plate to emit light simultaneously, thereby increasing the beam angle of the LED bulb and providing better heat dissipation.

[0004] The technical solution of this utility model: an LED bulb that emits light from all angles, comprising:

[0005] Lamp holder;

[0006] The mounting plate is vertically installed at the middle of the upper part of the lamp head;

[0007] The housing includes a first bubble and a second bubble respectively located on the front and rear sides of the mounting plate;

[0008] LED light-emitting components are located on both sides of the mounting plate.

[0009] In the aforementioned omnidirectional LED bulb, the LED light-emitting component includes a substrate, on which an LED driving circuit and an LED light source are provided.

[0010] In the aforementioned omnidirectional LED bulb, the mounting plate is provided with a light-transmitting edge, and the first bulb shell and the second bulb shell are respectively connected to the mounting plate through the light-transmitting edge.

[0011] In the aforementioned omnidirectional LED bulb, the light-transmitting edge and the cover are made of the same light-transmitting material.

[0012] In the aforementioned omnidirectional LED bulb, the cover is positioned and connected to the light-transmitting edge through a snap-fit ​​structure, and the cover is fixedly installed on the light-transmitting edge using ultrasonic welding technology.

[0013] In the aforementioned omnidirectional LED bulb, the snap-fit ​​structure includes a slot on the front and back sides of the light-transmitting edge and a strip on the upper edge of the cover.

[0014] In the aforementioned omnidirectional LED bulb, the shape and cross-sectional shape of the mounting plate match the axial cross-sectional shape of the LED bulb.

[0015] In the aforementioned omnidirectional LED bulb, the mounting plate is provided with a limiting component for positioning and limiting the LED light-emitting components.

[0016] In the aforementioned omnidirectional LED bulb, the limiting component includes a mounting post on the mounting plate and a mounting hole on the substrate, the shape of which matches the mounting post.

[0017] In the aforementioned omnidirectional LED bulb, the mounting plate has a lamp holder connector on its lower side, the lower end of the lamp holder connector has a corresponding insert block, and the upper end of the lamp holder connector has a slot for connecting the cover.

[0018] Compared with the prior art, the present invention has the following advantages:

[0019] 1. This application increases the beam angle by emitting light through LED light-emitting components on both sides of a vertically mounted mounting plate;

[0020] 2. This application uses a vertically arranged mounting plate as the core component of the light source, resulting in a larger LED light source mounting area. The mounting plate conducts the heat of the LED light-emitting components to the housing, increasing the external heat dissipation area and improving the heat dissipation effect. Therefore, while ensuring good heat dissipation, the power of the LED light source can be increased, further allowing for an increase in the number of LED light sources installed, resulting in a larger LED light source distribution area and enabling the LED bulb to emit light from all angles.

Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0026] Example 1. An LED bulb with omnidirectional light emission, configured as follows: Figure 1-3 As shown, it includes: a lamp head 1 for connecting to an external lamp holder; a mounting plate 3, vertically disposed at the upper middle part of the lamp head 1; a lamp head connector 7 is provided on the lower side of the mounting plate 3, the lower end of the lamp head connector 7 is provided with a corresponding insert 7.1 to the lamp head 1, and the upper end of the lamp head connector 7 is provided with a slot 7.2 for connecting a cover 4; the cover 4 includes a first bulb 4.1 and a second bulb 4.2 respectively disposed on the front and rear sides of the mounting plate 3; and an LED light-emitting component 5, disposed on both sides of the mounting plate 3, and powered by an AC-to-DC conversion through a power drive component disposed on one side of the substrate 5.1.

[0027] The LED light-emitting component 5 includes a substrate 5.1, on which an LED driving circuit 5.2 and an LED light source 5.3 are provided. The LED driving circuit 5.2 controls the LED light source.

[0028] The mounting plate 3 is provided with a light-transmitting edge seal 6. The first blister pack 4.1 and the second blister pack 4.2 are respectively connected to the mounting plate 3 through the light-transmitting edge seal 6, and the light-transmitting edge seal 6 and the cover 4 are made of the same light-transmitting material. Furthermore, the light-transmitting edge seal 6 and the cover 4 can be made of materials such as PC. The setting of the light-transmitting edge seal 6 can reduce the generation of black edges, and the use of the same light-transmitting material makes the light transmission effect better and more aesthetically pleasing when the first blister pack 4.1 and the second blister pack 4.2 are combined with the mounting plate.

[0029] The housing 4 is positioned and connected to the light-transmitting edge 6 via a snap-fit ​​structure. The housing 4 is fixedly installed on the light-transmitting edge 6 using ultrasonic welding technology. The snap-fit ​​structure includes slots 10 on the front and rear sides of the light-transmitting edge 6 and a retaining strip 11 on the upper edge of the housing 4. The snap-fit ​​structure enables the housing 4 to be initially fixed to the light-transmitting edge 6, thus facilitating the installation and welding of the housing 4 by ultrasonic equipment, thereby forming an integrated structure with more stable and reliable heat conduction and better heat dissipation.

[0030] The shape of the mounting plate 3 is matched with the axial cross-sectional shape of the LED bulb.

[0031] The mounting plate 3 is provided with a positioning component for positioning and limiting the LED light-emitting component 5. The positioning component includes a mounting post 8 on the mounting plate 3 and a mounting hole 9 on the substrate 5.1. The shape of the mounting hole 9 matches that of the mounting post 8. The mounting post 8 and the mounting hole 9 cooperate to position the substrate 5.1 relative to the mounting plate 3, and the connection is achieved through hot-melt technology, making the connection more stable and reliable.

[0032] The working principle of this application is as follows: A vertically arranged mounting plate made of light-transmitting material is used as the core component of the light source. LED light-emitting components 5 are provided on both sides of the mounting plate 3. By utilizing the light-emitting components on both sides of the mounting plate, the LED bulb emits light from all angles. The LED light-emitting components 5 are fixed by heat fusion. To improve the stability of the connection, mounting posts 8 can be provided on the mounting plate 3, and mounting holes 9 corresponding to the mounting posts 8 can be provided on the substrate 5.1 to achieve positioning between the substrate 5.1 and the mounting plate 3. Then, the first bulb shell 4.1 and the second bulb shell 4.2 are quickly connected to the mounting plate 3 through a snap-fit ​​structure. The lower part of the first bulb shell 4.1 and the second bulb shell 4.2 is provided with a connecting block, which can cooperate with the slot 7.2 at the upper end of the lamp holder connector 7 to achieve connection. Finally, ultrasonic welding is performed to make the connection more reliable. The light-transmitting edge 6 and the cover 4 are made of the same light-transmitting material, such as PC material. Furthermore, the mounting plate 3 is also made of the same material to form an integrated structure, which can effectively improve the heat dissipation effect. In addition, the setting of the light-transmitting edge 6 can reduce the proportion of dark areas during illumination and improve the lighting effect. This application utilizes a mounting plate as the core component of the light source, with LED light-emitting components installed on both sides of the mounting plate. This allows the mounting plate 3 to emit light from both sides, achieving omnidirectional light emission from the LED bulb. The light-transmitting edge sealing 6 further enhances the light transmission effect and avoids the generation of obvious black edges. Since the heat generated by the LED light-emitting components 5 can be transferred to the housing through the mounting plate 3, which has a large heat dissipation area and good heat dissipation effect, the power of the LED light source 5.3 can be increased while ensuring the lifespan and safety of the bulb, thus improving the illumination effect. Furthermore, the number of LED light sources 5.3 can be increased, resulting in a larger distribution area of ​​LED light sources 5.3 and improved light uniformity.

[0033] This application uses a commercially available Philips LED bulb as a comparative example to compare with Example 1. Both the comparative example and Example 1 adopt the A-series shape. The specific model of the comparative example is the economical LED bulb 9W E27 6500K. The comparison results are shown in Table 1:

[0034] Table 1. Comparison of functional parameters between Example 1 and the comparative example.

[0035]

[0036] The bulb temperature was measured using a temperature monitoring instrument after the comparative example and Example 1 had been running stably. The test results show that, while increasing the power compared to the comparative example, the bulb temperature in this application is lower. This demonstrates that the structure of this application, which transfers heat to the housing 4 via the mounting plate 3 and dissipates heat through the housing 4, has better heat dissipation performance, thereby improving the lighting effect while ensuring the bulb's lifespan and safety. Since the beam angle refers to the angle between two directions perpendicular to the beam centerline where the light intensity is equal to 50% of the strongest light, it is a fixed geometric characteristic that does not change with power. Increasing power only affects the total light output, i.e., the brightness of the light, but does not affect the beam angle. This application, tested according to standard GB / T 9468, achieves a beam angle of 320 degrees for the LED bulb. Compared to the 147-degree beam angle of traditional bulbs, the beam angle of this application is significantly increased, achieving omnidirectional light emission.

[0037] Example 2. Based on Example 1, the mounting plate is formed by fixing two sets of substrates 5.1 back to back. The LED light-emitting component 5 includes an LED driving circuit 5.2 and an LED light source 5.3 disposed on the surface of the substrate 5.1. This reduces the size of the mounting plate 3, saving costs, and the heat generated by the LED light-emitting component can be directly transferred to the cover 4 for effective heat dissipation.
