Description

Technical Field

[0001] This utility model relates to the field of LED lighting technology, and in particular to a high-power LED energy-saving blue bulb. Background Technology

[0002] LEDs, as a lighting source, have significant advantages such as energy saving, environmental protection, long lifespan, and fast response speed. They have been widely used in general lighting, special lighting, display screens, and other fields. As an important category of LED light source, blue LEDs play an irreplaceable role in special scenarios such as industrial inspection, stage lighting, plant lighting, and medical lighting due to their unique spectral characteristics.

[0003] Currently, high-power LED blue bulbs generate a lot of heat when working. If the heat cannot be dissipated in time, it will cause the junction temperature of the LED chip to rise, which will not only reduce luminous efficiency and cause serious light decay, but also significantly shorten the life of the bulb. Existing products mostly use simple aluminum shells for heat dissipation, which have limited heat dissipation area and unreasonable heat conduction paths, making it difficult to meet the heat dissipation requirements of high-power scenarios.

[0009] The optical lens is provided with a lamp core protective cover that is fixedly connected to the upper surface of the drive housing.

[0017] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0019] In this embodiment, a connecting lamp holder 101 is included. A connecting portion 102 is fixedly disposed above the connecting lamp holder 101, and a lamp cover 103 is disposed above the connecting portion 102. A driving housing 104 is fixedly disposed inside the connecting portion 102, and an LED substrate 105 is fixedly disposed inside the driving housing 104. A thermally conductive silicone pad 106 and a heat dissipation base plate 107 are sequentially disposed below the LED substrate 105. A plurality of heat dissipation protrusions 108 are fixedly disposed below the heat dissipation base plate 107. A heat dissipation mesh plate 109 is fixedly connected to the connecting portion 102 below the driving housing 104, and the heat dissipation mesh plate 109 extends through both sides of the connecting portion 102. The connecting lamp holder 101 is a standard interface design for connecting with an external lamp holder to achieve mechanical fixation and circuit conduction. The connector 102 is used to connect the lamp holder 101 and the lamp cover 103, and also provides installation space for internal components. The drive housing 104 is used to accommodate and protect internal components, and plays a role in fixing and protecting them. The thermally conductive silicone pad 106 fills the gap between the LED substrate 105 and the heat dissipation base plate 107, reducing thermal resistance and improving heat conduction efficiency. The heat dissipation base plate 107 achieves heat conduction through a large area of ​​metal material. Multiple heat dissipation protrusions 108 further increase the heat dissipation area and accelerate the diffusion of heat to the downward air. The heat dissipation mesh plate 109 runs through both sides of the connector 102, forming air convection channels on both sides of the heat dissipation protrusions 108, promoting heat dissipation, and effectively blocking external impurities, effectively solving the problems of insufficient heat dissipation area and obstructed heat dissipation path in traditional heat dissipation structures.

[0020] The LED substrate 105 is electrically connected to a driving circuit board 110 on its upper part, and electrically connected to a connecting lamp holder 101 via a wire 111 on its lower part. A blue LED chip 112 is electrically connected to the upper part of the driving circuit board 110, and the blue LED chip 112 penetrates the driving housing 104. The LED substrate 105 provides a mounting carrier for the blue LED chip 112 and the driving circuit board 110, and also has a heat conduction function. The driving circuit board 110 provides a stable driving current for the blue LED chip 112, converting the external AC power input into the DC power required by the blue LED chip 112. It also integrates an energy-saving control module to improve the energy utilization efficiency. The wire 111 enables the circuit connection between the LED substrate 105 and the connecting lamp holder 101, allowing external power to be transmitted to the LED substrate 105 through the connecting lamp holder 101 and the wire 111, and then distributed to the driving circuit board 110 and the blue LED chip 112, ensuring the stability and conductivity of the circuit connection.

[0021] Meanwhile, an optical lens 113 is provided on the outer side of the blue LED core 112 and is fixedly connected to the upper surface of the drive housing 104. A lens fixing ring 114 is provided at the bottom of the optical lens 113 and is fixedly connected to the upper surface of the drive housing 104. The optical lens 113 is made of transparent polymethyl methacrylate or polycarbonate, which has good light transmittance and can refract and diffuse the light emitted by the blue LED core 112, making the light distribution more uniform and reducing glare. The lens fixing ring 114 fixes the optical lens 113 to the drive housing 104 to prevent the lens from shifting or falling off during transportation or use, thereby improving structural stability.

[0022] In addition, a lamp core protective cover 115 is provided on the outer side of the optical lens 113 and is fixedly connected to the upper surface of the drive housing 104. The lamp core protective cover 115 is made of transparent quartz glass or high-strength transparent plastic material and is placed on the outer side of the optical lens 113. It can effectively block dust, moisture and other impurities from corroding the blue LED lamp core 112 and the optical lens 113, and at the same time avoid damage to the core components caused by external force collisions. It improves the protective performance and service life of the product without affecting the light output.

[0023] In this embodiment, a high-power LED energy-saving blue bulb is used by screwing the connecting lamp head 101 into a suitable external lamp holder to mechanically fix the bulb and connect the circuit. External power is input through the connecting lamp head 101, transmitted to the LED substrate 105 via the wire 111, and then distributed to the driver circuit board 110. The driver circuit board 110 rectifies, filters, and regulates the AC power, outputting a stable DC power required by the blue LED chip 112. When the blue LED chip 112 is powered on, it emits blue light. As the light passes through the optical lens 113, it is refracted and diffused by the optical lens 113 to form a uniform light. The lighting beam meets the lighting needs of different scenarios. The heat generated by the blue LED chip 112 during operation is transferred sequentially through the LED substrate 105 and the thermally conductive silicone pad 106 to the heat dissipation base plate 107. The heat dissipation base plate 107 disperses the heat to multiple heat dissipation protrusions 108. Heat dissipation is achieved through heat exchange between the heat dissipation protrusions 108 and the air. At the same time, the convection channel formed by the heat dissipation mesh plate 109 promotes air circulation and accelerates the air flow around the heat dissipation protrusions 108, further improving the heat dissipation efficiency. This effectively meets the heat dissipation needs of high-power blue LED bulbs during operation, ensuring stable bulb operation and extending bulb life.

[0024] The above-disclosed embodiment is merely a preferred embodiment of a high-power LED energy-saving blue bulb of the present invention, and should not be construed as limiting the scope of the present invention. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present invention still fall within the scope of the present invention.
