Abstract: An LED strip light for shelf signboards, comprises a strip-shaped lamp chamber, and an LED light-emitting module. The strip-shaped lamp chamber comprises a card board connecting edge, a non-transparent edge, an upper transparent edge and a lower transparent edge. The LED light-emitting module comprises at least one LED chip, and a strip-shaped lens. The strip-shaped lens includes an incident surface, a first fully reflecting surface, a second fully reflecting surface, a refractably reflecting surface. The first fully reflecting surface reflects all the incident lights thereon toward the upper light transparent edge. The second fully reflecting surface reflects all the incident lights thereon toward the refractably reflecting surface. And the outgoing light of the refractably reflecting surface is directed toward the lower transparent edge.

Abstract: An LED strip light for cabinet lighting includes a strip-shaped lamp holder, and a light-emitting module. The strip-shaped lamp holder includes a first mounting surface and a second mounting surface and two light source slots. The angle between the light source mounting surface formed by the two light source slots and the first mounting surface is an acute angle between 30 and 40 degrees. Two mounting groove is respectively provided on the first mounting surface and the second mounting surface along the extending direction thereof. One mounting groove is a U-shaped groove and another is a V-shaped groove. It is easier to install the LED strip light in the strip-shaped lamp holder and more mounting options can be selected so that the LED strip light is more suitable for cabinets such as shelf laminates, vertical freezers and horizontal freezers, etc.

Abstract: A plug-in multifunctional LED power system includes a power supply module, at least one output terminal, a switch module, a trigger conversion module, a compatible circuit module, and a replaceable control chip module. The trigger conversion module includes a first, second and third resistors connected in series from a high level output terminal to a ground. The switch module includes an N-type MOS transistor. The compatible circuit module is used for controlling on-off of the switching module by different control chip modules. The control chip module processes the input signal of the signal access unit and outputs a control signal for controlling the on/off of the switching unit so as to control the operating state of a LED lamp. The plug-in multi-functional LED power supply system can solve the increase of the production costs and the inconvenience for user installation caused by more existing power supply types and different models.

Abstract: A power supply system for shelving system includes a support arm, and an electrical supply device mounted on the mounting plate. The support arm includes a mounting hole, and a mounting plate disposed in the mounting hole. The thickness of the mounting plate is less that the depth of the mounting hole. The electrical supply device includes a circuit board, and a first protection cover covering the circuit board. The circuit board is clamping between the mounting plate and the first protection cover. A side wall of the first protection cover opposite to the circuit board is flush with a side wall of the mounting hole. The assembly of the support arm can be completed without being affected by the electrical supply device as long as the end of the support art can be inserted into the punched hole as the side wall of the first protection cover opposite to the circuit board is flush with the side wall of the mounting hole.

Abstract: An ultra-thin surface mounted LED lamp having surface emitting light includes a house, a light module, a reflection film, a light guide plate, and a plurality of light guide points provided on the light guide plate. The light module is striped and includes a plurality of LED chips. A maximum distance between the two LED chips at a head and tail of the light module accounts for two-thirds of the total circumference of the side walls. The light guide plate includes an incident wall configured for receiving the emitted light of the light module and a reflecting wall configured for reflecting light. A length of the incident wall is equal to the maximum distance between the two LED chips at the head and tail of the light module. The light guide points are spaced apart circular dots, the total area of which is 60% to 65% of the total area of the light guide plate.
