Description

Technical Field

[0001] This utility model relates to the field of lighting technology, specifically a lamp that allows for convenient adjustment of angle and power. Background Technology

[0002] Optimizing the performance of lighting fixtures remains a key focus of research and development, particularly in areas such as heat dissipation efficiency, ease of function adjustment, environmental protection, and current stability, where continuous improvement is needed. While existing lighting technology has made some progress, it still faces the following technical bottlenecks in practical applications:

[0003] Traditional LED lighting fixtures mostly employ passive heat dissipation using aluminum heat sinks or thermally conductive plastic shells, with some products utilizing aerodynamic design or additional fans to enhance convection. However, in high-power scenarios with multiple LEDs densely packed together, existing heat dissipation solutions still struggle to effectively address the problem of heat accumulation. For example, the thermal conductivity of aluminum heat sinks is limited by the material's coefficient of thermal expansion, and direct welding processes can lead to thermal stress damage to the LED chips. While thermally conductive plastics offer improved radiative heat dissipation capabilities, they still face the challenge of excessively high heat sink temperatures under sustained high-load operation. Furthermore, some products utilize heat pipe or liquid encapsulation technologies, but these are costly and complex to maintain, limiting their widespread adoption in general lighting.

[0004] Existing dimming and angle adjustment technologies for lighting fixtures have significant limitations. While traditional SCR dimming technology can adjust brightness through voltage chopping, it is prone to audio noise and flickering issues when used with LED driver circuits. PWM digital dimming technology, although flicker-free, requires dedicated driver circuitry and is not directly compatible with traditional dimming systems. Regarding angle adjustment, most products rely on mechanical structures to adjust lens position, a cumbersome process that struggles to achieve precise control. While some smart lighting fixtures support remote dimming, they lack localized physical adjustment interfaces, failing to meet the diverse needs of various usage scenarios.

[0005] Outdoor and industrial lighting fixtures must be waterproof, dustproof, and corrosion-resistant. Existing tri-proof lighting fixtures often employ sealing rings or ultrasonic welding processes, but these designs have weak points in terms of waterproofing at the adjustment interfaces. For example, traditional lighting fixtures often use a single sealed structure for the adjustment holes, which is prone to waterproofing failure after long-term use due to material aging or operational wear. Furthermore, while some products improve maintainability through modular design, a balance between sealing performance and ease of disassembly and assembly is difficult to achieve.

Furthermore, in practical applications, the shape, thickness, or height of each component may be enlarged or reduced. The embodiments listed in this utility model are merely illustrative and not intended to limit the scope of the utility model. Any obvious modifications or alterations made to this utility model do not depart from its spirit and scope.

[0050] like Figures 1 to 7As shown, a lamp with convenient angle and power adjustment includes a rear cover assembly 1 and a heat sink assembly 2. The heat sink assembly 2 is fixedly disposed on the front side of the rear cover assembly 1. The rear cover assembly 1 includes a rear cover 11, inside which a power supply 12, a DIP switch assembly 13, and a splitter assembly 14 are fixedly disposed. The DC output terminal 121 of the power supply 12 is connected to the splitter assembly 14, and the dimming output terminal 122 of the power supply 12 is connected to the DIP switch assembly 13. The DIP switch assembly 13 is connected to the splitter assembly 14. Ventilation slots 1128 are evenly distributed on the rear cover 11, and heat sinks 1129 are evenly distributed on the outer side of the rear cover 11. A bracket 3 is disposed on the heat sink assembly 2, and a light cut-off plate 4 is disposed on the upper front side of the heat sink assembly 2. The ventilation slots 1128 can fully utilize air convection to dissipate heat from the splitter assembly 14 and the power supply 12. The heat sinks 1129 can fully utilize conduction to dissipate heat from the splitter assembly 14 and the power supply 12.

[0051] like Figure 11 As shown, the DIP switch assembly 13 includes a DIP switch 131, on which a power adjustment switch 132 and an angle adjustment switch 133 are provided. A handle 134 is provided on the power adjustment switch 132 and the angle adjustment switch 133 respectively. An adjustable resistor 135 is provided on the DIP switch 131.

[0052] like Figure 12 As shown, the shunt plate assembly 14 includes an aluminum substrate 141, on which resistors 142 and diodes 143 are uniformly disposed.

[0053] like Figures 7 to 10 As shown, the rear cover assembly 1 also includes a heat sink 15. The heat sink 15 is provided with a mounting surface 151, a mounting B surface 152, a heat dissipation surface 153, and a heat sink through hole 154. The splitter plate assembly 14 is uniformly fixedly mounted on the mounting surface 151, and the DIP switch assembly 13 is fixedly mounted on the mounting B surface, so that the splitter plate assembly 14 is located between the heat sink 15 and the DIP switch assembly 13.

[0054] like Figure 3 , Figure 4 , Figure 5 and Figure 10 As shown, the back cover 11 has an integrated heat sink 111 inside. The heat sink 111 divides the back cover 11 into two cavities: the front cavity of the back cover 11 is the power supply cavity 112, and the rear cavity of the back cover 11 is the wiring cavity 113. The power supply 12 is fixedly installed on the front side of the heat sink 111 by the power supply fixing screw 1130. The DIP switch assembly 13, the splitter assembly 14, and the heat sink 15 are installed on the rear side of the heat sink 111 through the heat sink through hole 154 and the back cover stud 114 on the heat sink 111. The heat dissipation surface 153 of the heat sink 15 is in close contact with the heat sink 111.

[0055] like Figures 13 to 14 As shown, a cover plate 117 is fixedly installed on the rear side of the wiring cavity 113 of the rear cover 11 by cover plate screws 115 and cover plate through hole 116. An adjustment hole 118 is provided on the cover plate 117 and at the position corresponding to the DIP switch assembly 13. A silicone sleeve 119 and a pressure plate 1110 are provided on the outside of the adjustment hole 118. A plug 1112 is fixedly installed on the outside of the adjustment hole 118 by a threaded hole 1111 provided on the inner side of the silicone sleeve 119. The plug 1112 is an M40 plug and has plug threads 1113.

[0056] like Figures 15 to 21 As shown, the silicone sleeve 119 includes a silicone sleeve bottom plane 1114 and a silicone sleeve protruding surface 1115. The surface of the silicone sleeve protruding surface 1115 is set in a wave shape 1131, which can improve its extensibility and allow it to stretch and contract more freely during pulling and manipulating. Ribs 1116 are provided on the silicone sleeve bottom plane 1114. The ribs 1116 cooperate with the bottom plane of the cover plate through hole 116 to achieve better waterproof effect. The cover plate 117 is provided with an adjustment hole bottom plane 1117, a straight-lift sealing position 1118, and an adjustment hole stud 1119 corresponding to the adjustment hole 118. The ribs 1116 cooperate with the adjustment hole bottom plane 1117. A boss 1120 is provided where the silicone sleeve 119 cooperates with the pressure plate 1110, which cooperates with the groove 1121 on the pressure plate 1110 to prevent When the dial switch is turned, pulling may cause the silicone sleeve 119 to move, resulting in poor waterproofing. The silicone sleeve 119 is provided with a silicone sleeve through hole 1122, and the pressure plate 1110 is provided with a pressure plate through hole 1123. The pressure plate 1110 is fixedly connected by a screw 1124 passing through the silicone sleeve through hole 1122, the pressure plate through hole 1123 and the adjustment hole stud 1119. When the pressure plate 1110 presses the bottom surface of the silicone sleeve 119, the adhesive is squeezed outward. At this time, the adhesive blocking position 1118 blocks the adhesive from overflowing outward, achieving a good waterproofing effect.

[0057] like Figure 22 and Figure 23 As shown, a waterproof ring 1125 is provided between the plug 1112 and the silicone sleeve 119. The waterproof ring 1125 has a waterproof ring boss 1126, and the plug 1112 has a plug groove 1127. During assembly, the waterproof ring boss 1126 on the waterproof ring 1125 engages with the plug groove 1127 on the plug 1112, thus achieving a good waterproof effect. When adjusting the power and angle, the M40 plug 1112 and its waterproof ring 1125 can be unscrewed for adjustment. After adjustment, the plug 1112 and its waterproof ring 1125 should be tightened. If the plug 1112 and its waterproof ring 1125 are not tightened due to misoperation, the silicone sleeve 119 inside also provides a waterproof effect, preventing water and dust from entering the wiring cavity 113.

[0058] like Figure 24 and Figure 25 As shown, the heat sink assembly 2 includes a heat sink 21, which is fixedly installed on the front side of the rear cover 11. Inside the heat sink 21, a face ring 22, a lens 23 and a lamp board 24 are fixedly installed from front to back. LED beads 25 are evenly fixed on the lamp board 24, and the lamp board 24 is connected to the power supply 12.

[0059] The DC output terminal 121 of the power supply 12 of this utility model is connected to the shunt plate assembly 14. The shunt plate assembly is equipped with a number of resistors 142 and diodes 143. The current output ratio is adjusted by the shunt impedance through the resistors 142. Several ratios are mixed according to the angle settings, and then the angle is controlled by the DIP switch assembly 13. The DIP switch assembly 13 is equipped with an angle adjustment switch 133. Different settings can be adjusted by the handle 134 on the angle adjustment switch 133. When adjusted to different settings, the shunt plate assembly 14 will output the corresponding current to the lamp board 24 to control the current distribution ratio to the LED beads 25. The corresponding LED beads 25 on the lamp board 24 will display different brightness, and then emit different angles through the lens, thereby controlling the angle change. When there is stray current, it will be isolated by the diodes 143 to achieve the effect of current stabilization.

[0060] The power supply 12 of this utility model has a light output terminal 122 connected to a dial switch assembly 13. When the adjustment signal passes through the adjustable resistor 135 and is adjusted to the required power, the signal then reaches the power adjustment dial 132. The power adjustment dial 132 is equipped with a handle 134. When the handle 134 of the power adjustment dial 132 is moved to different positions, different power will be output. The power output can be achieved by adjusting the power adjustment dial 132.

[0061] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
