Description

Technical Field

[0001] The present invention relates to the technical field of lamps, and in particular to an LED point light source lamp. Background Art

[0002] LED (light-emitting diode) point light source is a new type of energy-saving and environmentally friendly decorative lamp. It uses LED cold light source to emit light, has a built-in microcomputer chip, can be programmed and controlled arbitrarily, and can achieve a variety of changing effects. It is a supplement to linear light source and floodlighting. Conventional LED point light source lamps achieve the lighting effect by setting LED on a circuit board and adding a light-transmitting shell.

[0003] However, most of the current LED point light sources can only emit light from one side, resulting in a small viewing angle of the LED point light source in actual application; and, in order to make the LED point light source waterproof, the traditional method is generally to achieve it through glue filling, but when used for a long time, the glue and the components of the LED point light source will chemically react, shortening the service life of the LED point light source; there is also a method of waterproofing through injection molding, but this method not only reduces the transmittance, but also the injection pressure generated during injection molding is easy to damage the components. Summary of the invention

[0004] Based on this, it is necessary to provide an LED point light source lamp to address the problem that most of the current LED point light sources can only emit light from one side, resulting in a small viewing angle of the LED point light source in actual application.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] An LED point light source lamp comprises an LED light board, a shell and a wire; the wire connects the LED light board and extends to the outside of the shell; the characteristic is that: the shell comprises a first shell and a second shell; LEDs are arranged on both sides of the LED light board, and the LED light board is arranged inside the shell; the shell surfaces of the first shell and the second shell corresponding to the light-emitting part of the LED light board are respectively a first transparent shell surface and a second transparent shell surface.

[0007] In one of the embodiments, the LED lamp board is provided with an annular rubber pad whose shape closely matches its edge, and an annular plug is provided at the position where the annular rubber pad corresponds to the connection between the LED light board and the wire, and the annular plug is provided with a rubber pad opening, and the wire passes through the rubber pad opening, and the annular rubber pad is pressed when the first shell and the second shell are fixedly connected to form a sealed environment inside.

[0008] In one of the embodiments, the surface of the annular rubber pad is seamlessly provided with annular raised patterns 360° along the pressing part, and the annular raised patterns form a circle along the annular surface of the annular rubber pad, and the annular raised patterns are pressed when the first shell and the second shell are fixedly connected.

[0009] In one of the embodiments, a first groove is provided at a position of the first shell corresponding to the connection between the LED light board and the wire, and a second groove is provided at a position of the second shell corresponding to the connection between the LED light board and the wire. The first groove and the second groove cooperate to form a wire hole; the inner edge shape of the rubber pad opening is closely matched with the shape of the wire, and the inner edge shape of the wire hole is closely matched with the outer edge of the annular plug.

[0010] In one embodiment, a first outer cover and a second outer cover are provided on the outside of the first outer shell and the second outer shell, the first outer cover and the second outer cover are fixedly connected, a first outer cover opening is provided at a position of the first outer cover corresponding to the first transparent shell surface, and a second outer cover opening is provided at a position of the second outer cover corresponding to the second transparent shell surface.

[0011] In one embodiment, the first outer cover is provided with an inner thread, and the second outer cover is provided with an outer thread matching the inner thread, so that the first outer cover and the second outer cover can be screwed together to achieve a fixed connection.

[0012] In one embodiment, the wires include 2 power wires and 3 signal wires, and the power wires and the signal wires are arranged side by side.

[0013] In one embodiment, the first outer cover and the second outer cover are respectively an aluminum first outer cover and an aluminum second outer cover.

[0014] In one embodiment, the first housing is provided with a snap-in groove, and the second housing is provided with a snap-in hook matched with the snap-in groove.

[0015] In one embodiment, the shell is a transparent PC material shell.

[0016] In one embodiment, the outer sheath of the wire is provided with a rubber sheath.

[0017] Compared with the prior art, the present invention achieves the following effects:

[0018] 1. LEDs are arranged on both sides of the LED light board, and the LED light board is arranged inside the shell. The shell surfaces of the first shell and the second shell corresponding to the light-emitting part of the LED light board are respectively the first transparent shell surface and the second transparent shell surface. The LED point light source lamp arranged in this way can realize double-sided light emission, so that the viewing angle of the LED point light source lamp is larger, thereby better showing the light-emitting effect. In addition, the wire connects the LED light board and extends to the outside of the shell, so that the light-emitting lamp of the LED point light source lamp can be easily controlled from the outside;

[0019] 2. By adding an annular rubber pad, the annular rubber pad and its annular plug are pressed when the first shell and the second shell are fixedly connected, so that a sealed environment is formed inside, which can achieve functions such as waterproof and dustproof. At the same time, because waterproofing is achieved by pressing the annular rubber pad, a series of problems that may be caused by traditional waterproofing methods such as glue filling and injection molding are avoided;

[0020] 3. The first outer cover and the second outer cover can be more firmly screwed and fixedly connected through the screw thread, and can make the first shell and the second shell closer together, thereby increasing the pressure on the annular rubber pad to enhance the waterproof sealing performance; at the same time, the spiral rotation method is convenient for production and assembly, with high efficiency and low cost.

[0029] See also Figure 1 As shown, it is a schematic diagram of the structure of an embodiment of an LED point light source lamp of the present invention, wherein the LED point light source lamp in the embodiment comprises an LED lamp board 1, a housing 2 and a wire 3; the wire 3 is connected to the LED lamp board 1 and extends to the outside of the housing 2; the housing 2 comprises a first housing 21 and a second housing 22; LEDs 11 are arranged on both sides of the LED lamp board 1, and the LED lamp board 1 is arranged inside the housing 2; the shell surfaces of the first housing 21 and the second housing 22 corresponding to the light-emitting part of the LED lamp board 1 are respectively a first transparent shell surface 213 and a second transparent shell surface 223; after the overall assembly, Figure 2 shown.

[0030] According to the above-mentioned LED point light source lamp, LEDs 11 are arranged on both sides of the LED light board 1, and the LED light board 1 is arranged inside the shell 2. The shell surfaces of the first shell 21 and the second shell 22 corresponding to the light-emitting part of the LED light board 1 are respectively the first transparent shell surface 213 and the second transparent shell surface 223. The LED point light source lamp arranged in this way can realize double-sided light emission, so that the viewing angle of the LED point light source lamp is larger, thereby better showing the light-emitting effect, and the wire 3 connects the LED light board 1 and extends to the outside of the shell 2, which can conveniently realize the control of the light-emitting state of the LED point light source lamp from the outside.

[0031] In one of the embodiments, an LED control chip is further included. The LED control chip is arranged on the LED lamp board 1 , the LED 11 is connected to the LED control chip, and the LED control chip is connected to the wire 3 .

[0032] In this embodiment, by adding an LED control chip, such as a DMX512 chip, to the LED light board 1, the lighting state of the LED point light source lamp can be controlled through a program, thereby improving the convenience of controlling the lighting state of the LED point light source lamp.

[0033] In one embodiment, the housing 2 is a transparent PC material housing.

[0034] In this embodiment, the shell 2 is made of transparent PC (Polycarbonate) material, so that the shell 2 has a series of advantages such as good light transmittance, heat insulation, aging resistance, flame retardancy, adaptability to large temperature differences, and impact resistance, thereby extending the service life of the LED point light source lamp.

[0035] In one embodiment, see Figure 2 As shown, the outer side of the wire 3 is covered with a rubber sleeve 33 .

[0036] In this embodiment, considering that most of the LED point light source lamps are used outdoors, a rubber sleeve 33 is added to the outside of the wire 3 to enhance the wire's anti-pulling and anti-corrosion properties to cope with the harsh environment that may exist when used outdoors, thereby extending the service life of the LED lamp.

[0037] In one embodiment, see Figure 3 As shown, the LED lamp board 1 is provided with an annular rubber pad 4 whose shape closely matches its edge, and an annular rubber pad 4 is provided with an annular plug 41 corresponding to the position where the LED lamp board 1 is connected with the wire 3. The annular plug 41 is provided with a rubber pad opening 42, and the wire 3 passes through the rubber pad opening 42. When the first shell 21 and the second shell 22 are fixedly connected, the annular rubber pad 4 is pressed tightly to form a sealed environment inside.

[0038] In this embodiment, an annular rubber pad 4 is added, and the annular rubber pad 4 and its annular plug 41 are compressed when the first shell 21 and the second shell 22 are fixedly connected, so that a sealed environment is formed inside, and functions such as waterproof and dustproof can be achieved. At the same time, because waterproofing is achieved by compressing the annular rubber pad, a series of problems that may be caused by traditional waterproofing methods such as glue filling and injection molding are avoided.

[0039] In one embodiment, see Figure 4 As shown, the surface of the annular rubber pad 4 is seamlessly provided with annular raised patterns 43 360° along the pressing part. The annular raised patterns 43 form a circle along the annular surface of the annular rubber pad 4. The annular raised patterns 43 are pressed when the first shell 21 and the second shell 22 are fixedly connected. The pressing part is the part that is pressed when the first shell 21 and the second shell 22 are fixedly connected.

[0040] In this embodiment, by providing an annular raised pattern 43 on the surface of the annular rubber pad 4, the annular rubber pad 4 and its annular plug 41 can be better compressed when the first shell 21 and the second shell 22 are fixedly connected, thereby improving the sealing inside the shell 2.

[0041] In one embodiment, see Figure 4 As shown, the first shell 21 is provided with a first groove 211 at the position corresponding to the connection between the LED light board 1 and the wire 3, and the second shell 22 is provided with a second groove 221 at the position corresponding to the connection between the LED light board 1 and the wire 3. The first groove 211 and the second groove 221 cooperate to form a wire hole 23; the inner edge shape of the rubber pad opening 42 is closely matched with the shape of the wire 3, and the inner edge shape of the wire hole 23 is closely matched with the outer edge of the annular plug 41.

[0042] In this embodiment, the inner edge shape of the rubber pad opening 42 is closely matched with the shape of the wire 3, and the inner edge shape of the wire hole 23 is closely matched with the outer edge of the annular plug 41. When the first shell 21 and the second shell 22 press the annular rubber pad 4, the position of the annular rubber pad 4 corresponding to the wire 3 will not easily produce holes, thereby improving the waterproof effect of the LED point light source lamp.

[0043] In one embodiment, the inner edge shape of the rubber pad opening 42 is closely matched with the outer edge of the rubber sleeve 33 , and the inner edge shape of the wire hole 23 is closely matched with the outer edge of the annular plug 41 .

[0044] In one embodiment, see Figure 5 As shown, the wires 3 include two power wires 31 and three signal wires 32 , and the power wires 31 and the signal wires 32 are arranged side by side.

[0045] In this embodiment, the power wire is used to supply power to the LED point light source lamp, and the signal wire is used to control the lighting state of the LED point light source lamp; by arranging the power wire and the signal wire side by side, the wires can be made flat as a whole. When the first shell 21 and the second shell 22 press the annular rubber pad 4, the position of the annular rubber pad 4 corresponding to the wire 3 will not easily produce holes, thereby improving the waterproof effect of the LED point light source lamp.

[0046] Optionally, the specification of the power supply wire 31 can be 1 mm 2 , which can reduce the voltage drop when a large current passes through the power wire 31, thereby reducing power loss; the specification of the signal wire can be 0.3 mm 2 , which can reduce costs.

[0047] In one embodiment, see Figure 6 As shown, the first housing 21 is provided with a snap-fitting groove 212 , and the second housing 22 is provided with a snap-fitting hook 222 matched with the snap-fitting groove 212 .

[0048] In this embodiment, the first housing 21 and the second housing 22 can be snap-fitted with the snap-fitting groove 212 and the snap-fitting hook 222 to form a relatively stable structure that is simple and easy to implement.

[0049] In one embodiment, see Figure 7 As shown, the first outer shell 21 and the second outer shell 22 are covered with a first outer cover 51 and a second outer cover 52, the first outer cover 51 and the second outer cover 52 are fixedly connected, the first outer cover 51 is provided with a first outer cover opening 511 at a position corresponding to the first transparent shell surface 213, and the second outer cover 52 is provided with a second outer cover opening 521 at a position corresponding to the second transparent shell surface 223; after the overall assembly is completed, Figure 8 shown.

[0050] In this embodiment, by respectively adding a first outer cover 51 and a second outer cover 52 on the outside of the first outer shell 21 and the second outer shell 22, and fixing the first outer cover 51 and the second outer cover 52 in connection, the structure of the LED point light source lamp can be made more stable; at the same time, the first outer cover 51 and the second outer cover 52 are respectively provided with a first outer cover opening 511 and a second outer cover opening 521 at positions corresponding to the transparent shell surfaces 24, so that the light of the internal LED 11 can respectively pass through the first transparent shell surface 213 and the second transparent shell surface 223 to emit to the outside of the first outer cover 51 and the second outer cover 52.

[0051] In one embodiment, see Figure 8 As shown, the first outer cover 51 is provided with an inner thread 512, and the second outer cover 52 is provided with an outer thread 522 matching the inner thread, so that the first outer cover 51 and the second outer cover 52 can be screwed together to achieve a fixed connection.

[0052] In this embodiment, the first outer cover 51 and the second outer cover 52 can be more securely screwed and fixed together through screw threads, and can make the first shell 21 and the second shell 22 closer together, thereby increasing the pressure on the annular rubber pad 4 to enhance the waterproof sealing performance; at the same time, the spiral rotation method is convenient for production and assembly, with high efficiency and low cost.

[0053] Optionally, the first outer cover 51 and the second outer cover 52 may be fixedly connected by screwing to improve the structural stability of the LED point light source lamp.

[0054] Optionally, the first outer cover 51 and the second outer cover 52 can be fixedly connected by a PC plastic buckle to improve the convenience of production and installation of the LED point light source lamp.

[0055] In one embodiment, the first outer cover 51 and the second outer cover 52 are respectively an aluminum first outer cover and an aluminum second outer cover.

[0056] In this embodiment, by selecting aluminum as the material of the first outer cover 51 and the second outer cover 52, the structural stability of the LED point light source lamp is improved while the weight is light, thereby improving the convenience of carrying and installing the LED point light source lamp.

[0057] Optionally, the aluminum first outer cover and the aluminum second outer cover are both die-cast aluminum, which can reduce production costs.
