DETAILED DESCRIPTION

[0022] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0023] Embodiment 1. A method for achieving full-angle lighting of an LED bulb, with a vertically arranged mounting plate as the core component of the light source, LED light-emitting components are arranged on both sides of the mounting plate, and a cover is used to enclose the LED light-emitting components on both sides to form a complete bulb cover of the LED bulb; by utilizing the LED light-emitting components on both sides of the mounting plate to emit light, and at the same time utilizing the mounting plate to transfer the heat generated by the LED light-emitting components to the cover for heat dissipation, the full-angle lighting of the LED bulb is achieved. The mounting plate 3 is arranged vertically, so that the LED light-emitting components can be arranged on both sides of the mounting plate, so that both sides of the mounting plate emit light, solving the technical problem that the rear side of the LED light-emitting components cannot be illuminated, and the heat generated by the LED light-emitting components during operation can be transferred to the cover through the mounting plate, thereby improving the heat dissipation efficiency of the bulb.

[0024] An LED bulb lamp using the above-mentioned method for realizing full-angle lighting of an LED bulb lamp comprises: a lamp holder 1 for connecting to an external lamp holder; a mounting plate 3 vertically arranged at the middle of the upper end of the lamp holder 1; a lamp holder connector 7 is arranged at the lower side of the mounting plate 3, a plug block 7.1 corresponding to the lamp holder 1 is arranged at the lower end of the lamp holder connector 7, and a slot 7.2 for connecting to a cover shell 4 is arranged at the upper end of the lamp holder connector 7; the cover shell 4 comprises a first bulb shell 4.1 and a second bulb shell 4.2 respectively arranged at the front and rear sides of the mounting plate 3; an LED light-emitting component 5 is arranged at both sides of the mounting plate 3, and converts AC to DC through a group of power drive components to realize power supply.

[0025] The LED light emitting assembly 5 comprises a substrate 5.1, on which an LED driving circuit 5.2 and an LED light source 5.3 are arranged. The LED light source is controlled by the LED driving circuit 5.2.

[0026] The mounting plate 3 is provided with a light-transmitting edge seal 6, and the first bulb shell 5 and the second bulb shell 6 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 shell 4 are made of the same light-transmitting material. The provision 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-transmitting effect better and more beautiful when the first bulb shell 5 and the second bulb shell 6 are combined with the mounting plate.

[0027] The light-transmitting edge seal 6 is positioned and connected with the housing 4 through a buckle structure, and is fixed to the housing 4 through ultrasonic welding technology. The buckle structure can achieve preliminary fixation between the housing 4 and the light-transmitting edge seal 6, so that it is more convenient for ultrasonic equipment to install and weld the housing 4, thereby forming an integrated structure, making heat conduction more stable and reliable, and having a better heat dissipation effect.

[0028] The cross-sectional shape of the mounting plate 3 matches the axial cross-sectional shape of the LED bulb.

[0029] The working principle of the present application is that the present application adopts a vertically arranged mounting plate made of a light-transmitting material 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 LED light-emitting components on both sides of the mounting plate to emit light, the full-angle light output of the LED bulb is achieved. The LED light-emitting components 5 are fixed by hot melting. In order to improve the stability of the connection, a mounting column 8 can be further provided on the mounting plate 3, and a mounting hole 9 corresponding to the mounting column 8 can be provided on the substrate 5.1 to achieve the positioning of 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 the snap-on structure, and the first bulb shell 4.1 and the second bulb shell 4.2 are provided with a connecting block at the bottom, which can be connected with the slot 7.2 at the upper end of the lamp holder connector 7, and finally welded by ultrasonic equipment, so that the connection is more reliable. The light-transmitting edge seal 6 and the cover shell 4 are made of the same light-transmitting material, such as PC material, and the mounting plate 3 is also made of the same material to form an integrated structure, which can effectively improve the heat dissipation effect, and the setting of the light-transmitting edge seal 6 can reduce the proportion of dark areas during lighting and improve the lighting effect. The present application uses the mounting plate as the core component of the light source, and LED light-emitting components are set on both sides of the mounting plate, so that the mounting plate 3 of the present application emits light on both sides, realizing the full-angle light emission of the LED bulb lamp, and the light-transmitting edge seal 6 can further improve the light-transmitting effect and avoid the generation of obvious black edges. Since the heat generated by the LED light-emitting component 5 can be transferred to the cover through the mounting plate 3, it has a large heat dissipation area and a good heat dissipation effect. Therefore, under the premise of ensuring the service life and safety of the bulb lamp, the power of the LED light source 5.3 can be increased and the lighting effect can be improved. The number of LED light sources 5.3 can be further increased, so that the distribution area of ​​the LED light sources 5.3 is larger, thereby improving the uniformity of light.

[0030] This application uses a commercially available Philips bulb as a comparative example for comparison with Example 1. Both the comparative example and Example 1 use the A series appearance. The specific model of the comparative example is an economical LED bulb 9W E27 6500K. The comparison results are shown in Table 1:

[0031] Table 1, comparison of functional parameters between Example 1 and comparative example

[0032] Example 1 Comparative Example Product size Φ60*108mm Φ60*108mm power 10W 9W Bulb temperature 105℃ 108℃ Beam angle 320 degrees 147 degrees

[0033] The temperature of the bulb lamp beads is measured by a temperature inspection instrument after the comparative example and Example 1 are running stably. The test results show that the temperature of the bulb lamp beads is lower while the power is increased compared with the comparative example, which proves that the structure of the present application that transfers heat to the cover 4 through the mounting plate 3 and dissipates heat through the cover 4 has good heat dissipation performance, thereby improving the lighting effect under the premise of ensuring the service life and safety of the bulb lamp. The beam angle refers to the angle between the two directions where the light intensity of the vertical beam center line is equal to 50% of the strongest light. It is a fixed geometric characteristic and will not change due to changes in power. The increase in power will only affect the total output of light, that is, the brightness of the light will increase, but will not affect the size of the beam angle. The present application is tested in accordance with the implementation standard GB / T 9468. The beam angle of the LED bulb can reach 320 degrees. Compared with the beam angle of 147 degrees of the traditional bulb lamp, the beam angle of the present application is significantly increased to achieve full-angle luminescence.

[0034] Embodiment 2. Based on Embodiment 1, the mounting plate is formed by fixing two sets of substrates 5.1 back to back, and the LED light emitting assembly 5 includes an LED driving circuit 5.2 and an LED light source 5.3 arranged on the surface of the substrate 5.1. This reduces the arrangement of the mounting plate 3 and saves costs, and the heat generated by the LED light emitting assembly can be directly transferred to the cover 4 for effective heat dissipation.
