Description

Technical Field

[0001] The utility model relates to the technical field of light source boards, and in particular to a heat dissipation type integrated LED light source board. Background Art

[0002] As we all know, human life cannot do without lighting. Lighting not only brings great convenience to people's lives, but also plays an important role in beautifying people's lives. Today, when various energy sources are scarce, LED lights play an increasingly important role in the field of lighting with their characteristics of focusing, less heat, power saving, long service life, fast response rate and small size. In addition, the manufacturing technology of high-power LEDs has become increasingly advanced and stable in recent years. It has gradually replaced traditional small tungsten filament bulbs and is widely used in various products.

[0003] Most of the existing LED light source boards have poor heat dissipation effect during use, which will affect the service life and is not conducive to use. In response to this phenomenon, a Chinese utility model patent with authorization announcement number CN217356527U has been published, which discloses an LED light source board with a heat dissipation structure, including a light source board body and two groups of heat sinks, one side of the light source board body is symmetrically provided with fixing grooves, and the two groups of heat sinks are respectively installed on the inner sides of the two groups of fixing grooves, a fixing block is installed on one side of the light source board body, a limiting assembly is installed on one side of the fixing block, a slot is opened on one side of the top of the fixing block, and a limiting plate is installed on one side of the heat sink. The limiting plate is plugged into the inner side of the slot, one side of the limiting plate is set as an arc structure, one side of the limiting plate is provided with a limiting hole, one end of the limiting component extends to the inner side of the slot and is plugged into the inner side of the limiting hole, and the cross-section of the limiting hole is set as a circular structure. It can be seen that this is achieved by adding a heat dissipation structure to the structure of the LED light source board. The heat dissipation structure can enhance the heat dissipation effect of the LED light source board, thereby extending the service life of the LED light source board. This requires adding a heat dissipation structure separately, which requires adding a process of separately installing the heat dissipation structure, which is bound to increase the production cost, and is not conducive to meeting the mass production requirements of current manufacturers. Utility Model Content

[0004] 1. Technical issues that need to be resolved

[0005] In view of the shortcomings of the prior art, the utility model provides a heat dissipation integrated LED light source board, which has a more reasonable design and is more conducive to reducing the difficulty of production and manufacturing, further reducing the cost investment of manufacturing enterprises, and is more conducive to meeting the mass production requirements of current manufacturing enterprises.

[0006] (II) Technical solutions that need to be adopted

[0007] To achieve the above object, the technical solution adopted by the present utility model is as follows:

[0008] A heat-dissipating integrated LED light source board, comprising a substrate and a plurality of LED lights arranged on the substrate. Creases for bending are provided on both sides of the substrate. By bending the two sides of the substrate downward through the creases, a base in an inverted "U" shape is formed, and a transparent light source cover for covering the LED lights is provided on the base.

[0009] Preferably, the crease is a crease groove provided on the upper surface. By bending towards the back surface of the substrate based on the crease groove, at this time, the two side parts of the substrate are perpendicular to the middle part of the substrate to form the base.

[0010] Preferably, the LED lights are soldered on the substrate.

[0011] Preferably, the substrate is a light source substrate, the LED lights are arranged in a multi-ring circular arrangement, the number of LED lights in each ring increases exponentially from the inside to the outside, all the LED lights are arranged radially on the substrate, and a fluorescent glue is covered on the LED lights, and the fluorescent glue is circular.

[0012] Preferably, the LED lights are connected in series and parallel by conductive silver paste.

[0013] Preferably, the transparent light source cover is locked on the substrate through fasteners.

[0014] Preferably, a terminal is provided on the substrate, the terminal is connected to a power cord, the power cord is connected to a driving power source, and the driving power source is connected to a connecting wire for connecting to an external power source.

[0015] Preferably, a positioning hole is provided at the center of the substrate.

[0016] (III) Beneficial effects to be achieved

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0018] First, creases for bending are provided on both sides of the substrate of the present utility model. The two sides of the substrate are bent downward through the creases to form a base in an inverted "U" shape, and a transparent light source cover for covering the LED lamp is provided on the base. Its design is more reasonable and is more conducive to reducing the manufacturing difficulty, further reducing the cost investment of manufacturing enterprises, and is more conducive to meeting the mass production requirements of current manufacturing enterprises. More importantly, only forming a base in an inverted "U" shape can achieve a good heat dissipation effect. After testing during use, the temperature is generally between 60°C and 70°C, avoiding the problem of component burnout due to excessive temperature, and is conducive to avoiding the setting of multiple heat sinks or other heat dissipation mechanisms on the base, greatly reducing the cost investment in production and manufacturing.

[0019] Second, the crease of the present utility model is a crease groove provided on the upper surface. By bending towards the back of the substrate based on the crease groove, the two side parts of the substrate are perpendicular to the middle part of the substrate at this time to form a base. This setting is conducive to the formation of the base and facilitates the later installation of the base. This is conducive to avoiding the setting of heat sinks or other heat dissipation mechanisms on the base, not only greatly reducing the cost investment in production and manufacturing, but also the temperature after testing of this kind of base with multiple LED lamps is generally between 60°C and 70°C, avoiding the problem of component burnout due to excessive temperature.

[0035] Embodiment 5: It can be described based on Embodiment 1 or Embodiment 2 or Embodiment 3 or Embodiment 4.
