Description

TECHNICAL FIELD

[0001] The utility model relates to the field of waterproof lamp, especially to an outdoor waterproof LED lamp. BACKGROUND

[0002] Most of the outdoor LED bulbs adopt SMD patch light source or LED filament. Due to limited heat dissipation conditions, the luminous brightness cannot be designed too high, and the light efficiency is general. The outdoor LED bulb also needs to be waterproof. Most of the similar products on the market only do waterproof treatment on the lampshade. The gap between the hollow cup lamp holder and the lampshade is easy to penetrate water, which is also invisible to the naked eye. Long-term use can easily cause oxidation and corrosion of the internal wires of the hollow cup lamp holder, causing circuit hazards and maintenance. Although many waterproof structures consider this situation and install waterproof parts inside the hollow cup lamp holder, the waterproof parts are damaged by heat for a long time, which causes melting or deformation in the hollow cup lamp holder, resulting in poor waterproof effect and difficulty in removing and replacing. SUMMARY

[0003] In order to improve the waterproof ability of the LED lamp and prolong the service life of the lamp body, the utility model provides an outdoor waterproof LED lamp.

[0004] The outdoor waterproof LED lamp provided by the utility model adopts the following technical scheme:

[0005] An outdoor waterproof LED lamp comprises a lampshade, a light source plate, a hollow cup lamp holder and a plug part. When the plug part is located in the hollow cup lamp holder, the peripheral wall of the plug part is tightly attached to the inner peripheral wall of the hollow cup lamp holder, and the top wall of the plug part is tightly attached to the inner bottom wall of the hollow cup lamp holder away from the lampshade.

[0006] The light source plate is connected with a resistor, one end of the plug part away from the lampshade is provided with a conductive body, one end of the resistor is electrically connected with the light source plate, the other end of the resistor penetrates through the conductive body and extends to the top end of the lamp part, the conductive body is provided with a through hole for the first pin of the resistor to penetrate out, and the through hole is covered with a welding part.

[0007] The resistor and the conductive body arranged at both ends of the plug part are limited in movement by the welding part, so that the resistor is not easy to separate from the plug part, and the conductive body is also not easy to separate from the plug part. The light source plate protrudes outside the hollow cup lamp holder, so that the plug part can be pulled out synchronously by pulling the light source plate. When the plug part is damaged, the plug part can be conveniently replaced, so that the plug part is more easy to maintain and replace, and the stability of the fixed connection of the conductive body and the resistor with the plug part and the simplicity of assembly are improved.

[0008] The welding part closes the open end of the perforation, so that water is not easy to flow into the interior of the lamp from the perforation, and the welding part can further fix the first pin of the resistor, so that the resistor is stably installed in the waterproof seat, and the resistor and the conductor are fixed by the welding part, so that the stable conduction of the resistor and the conductor is maintained, and the conductor is further fixed to prevent the conductor from being separated from the plug part, which is beneficial to improve the connection tightness of the overall structure.

[0009] Preferably, the light source plate is provided with an LED light source, and the LED light source is provided with a COB packaging layer, which has better light efficiency and heat dissipation performance than an SMD lamp bead.

[0011] Preferably, the welding part is a tin bead.

[0012] Preferably, the hollow cup lamp holder is connected with the end of the lampshade through a thread, so that the waterproof ring provided on the bottom surface of the plug part abuts against the inner surface of the hollow cup lamp holder.

[0013] The waterproof ring is driven to move by the connection of the hollow cup lamp holder and the lampshade, so that the waterproof ring is clamped between the hollow cup lamp holder and the lampshade, further sealing the connection gap between the hollow cup lamp holder and the lampshade, so that the waterproof ability of the overall waterproof lamp is stronger.

[0014] Preferably, the plug part is provided with a plug hole, the resistor is plugged into the plug hole, the plug part is a soft rubber plug, and the resistor is in interference fit with the plug hole.

[0015] The resistor is fixed by the interference fit between the rubber plug and the resistor, so that the fixing operation of the resistor is simple.

[0016] Preferably, the plug part is further provided with a connecting hole, the connecting hole is in communication with the plug hole, and the conductor is plugged into the connecting hole and abuts against the inner side wall thereof.

[0017] The connecting hole and the plug hole can guide the first pin of the resistor, so that the first pin of the resistor is more easily penetrated through the conductor, the resistor is more easily assembled on the plug part, and the conductor is pre-fixed, so that the installation and cooperation between the conductor and the plug part are more easily operated.

[0018] Preferably, the conductor includes a plug column and a copper cap, the side wall of the plug column is in interference fit with the hole wall of the connecting hole, and the diameter of the copper cap is greater than the diameter of the connecting hole.

[0019] The copper cap limits the depth of the conductor plugged into the plug part for subsequent installation.

[0020] Preferably, the copper cap is recessed with a limiting groove on the side away from the inserting column.

[0021] During welding, the solder flows to the limiting groove after melting, which is beneficial to assist welding, and makes the connection between the welding part, the first pin and the conductive body more stable after welding.

[0022] Preferably, the light source plate is connected with an electrode L and an electrode N, and the electrode N extends out of the lampshade and is opposite to the electrode L located in the lampshade.

[0023] Preferably, the plug part is provided with a mounting hole adjacent to the surface inside the lampshade, which is used for positioning the light source plate of the electrode L and the electrode N.

[0024] Preferably, the electrode N is folded to the head of the lampshade in a zigzag manner.

[0025] Preferably, the resistance is welded and fixed with the electrode L away from the first pin of the welding part.

[0026] In summary, the utility model has the following beneficial technical effects:

[0027] In the technical scheme, the resistance and the conductive body arranged at both ends of the plug part are limited from moving by the welding part, so that the resistance is not easy to separate from the plug part, and the conductive body is also not easy to separate from the plug part, which is beneficial to improve the stability of the fixed connection of the conductive body and the resistance with the plug part and the simplicity of assembly.

[0035] The light source plate 2 is connected with a resistor 5, the end of the plug part 4 away from the lampshade 1 is provided with a conductive body 6, one end of the resistor 5 is electrically connected with the light source plate 2, the other end penetrates through the conductive body 6 and extends to the top end of the lamp part, the conductive body 6 is provided with a through hole 8 for the first pin 18 of the resistor 5 to pass through, and the through hole 8 is covered with a welding part 7, which is used to connect the first pin 18 of the resistor 5 and the conductive body 6.

[0036] The resistor 5 and the conductive body 6 arranged at both ends of the plug part 4 are limited in movement by the welding part 7, so that the resistor 5 is not easy to separate from the plug part 4, and the conductive body 6 is also not easy to separate from the plug part 4, which is beneficial to improve the stability of the fixed connection of the conductive body 6 and the resistor 5 and the ease of assembly.

[0037] The welding part 7 closes the opening of one end of the through hole 8, so that water is not easy to flow into the inside of the lamp from the through hole 8, the welding part 7 can further fix the first pin 18 of the resistor 5, so that the resistor 5 is stably installed in the waterproof seat, and the resistor 5 and the conductive body 6 are fixed by the welding part 7, which can not only keep the stable conduction of the resistor 5 and the conductive body 6, but also further fix the conductive body 6 to prevent the conductive body 6 from separating from the plug part, which is beneficial to improve the connection tightness of the overall structure.

[0038] In the patent 202320717401.3, since the conductive body 6 will finally be exposed outside the hollow cup lamp holder 3, in order to ensure the stability of waterproof, the conduction mode between the conductive body 6 and the resistor 5 is to make the end parts of the two abut together, in order to keep the stable conduction of the two, many structures are set to prevent the two from separating, resulting in a very complex structure. The present scheme closes the through hole 8 through which the first pin 18 of the resistor 5 passes by the welding part 7, which not only ensures the stable conduction of the resistor 5 and the conductive body 6, but also simplifies the overall structure, so that each part is easier to process.
