External Shell Material
Contour Shape
Waterproofing Treatment Method
Non-watertight
The non-watertight modules have competitive price which is suitable for the light emitting sources of indoor signage, sign board and light box.
Glue Drip Waterproof
The glue drip waterproof is to drip AB glue (epoxy glue) on. Being a common waterproof method, the glue drip waterproof level can reach more than IP65 and it is able surfacing without scratches. Widely used for 3D channel letters, sign boards, signage, light box, landscape layout, decor, etc.
Injection Molding
The injection molded modules, as its name indication, is a component composed by the LED lamp beads which to be pasted on PCB then to attach with the wire pressed out from adhesive the injection molding machine. The main models are 5050, 3528, 5630, etc.
Its waterproof grade reaches maximally IP68. Beautiful appearance, cold resistant and heatproof, its shell colors unfading and good protection to its internal circuit.
LED injection molded modules is one kind of LED modules which compares with other kinds of modules, it produces bigger light emitting angle, high luminosity, and low light degradation, hence to be used widely.
Color Temperature Analysis
The LED emitting color varies depending on different wavelengths, Blue, Purple, Red, Green, Yellow and Colorful are all possible to customize.
Luminosity Analysis
The unit of luminous flux is “lumen”. Generally, the luminous flux is symbolized by Φ and in theory its unit is like the watt in electrics that because the vision is related with light and colors. Therefore, according to the standard light source and normal vision for measurement to use “lumen”, the symbol is “lm”.
The luminosity is the physical quantity of strong and weak light (reflective light) from a luminous body (or a reflective body). The human eye observes the light source from one direction, and from this direction, the ratio of light intensity and light source the human eye captured to be defined as the luminosity of the light source, i.e. the light emitting intensity on a single unit of the projected area. The luminosity is symbolized by L and the luminosity unit is candela per square meter (cd/m2).
Hence under a certain angle, the luminous flux results the luminosity intensity, however, the luminous flux is in direct proportion to the power.
Power Supply Selection
The calculation for the suited power supply quantity of the modules: Module Quantity * Per Module Power / Power of a Single Switch Electrical Source Piece / 0.8 then round the value up which shall be the quantity of electrical source pieces. Using 500 pieces of 2835 modules, for example, each module’s power is 0.72W, and choose a 60W Switch Electrical Source then the calculation shall be 500*0.72 / 60 / 0.8=7.5 pieces. As it is to select a round number, the quantity will be 8 pieces electrical source at 60W.
Installation
During layout installation of LED modules, the user shall pay attention on average and reasonable layout. Keep each of the modules an 1~1.5cm horizontal gap and a 3~4cm vertical gap, and making the layout beautiful is the principle.
Module Fixed Mode:
The backside of plastic cement shell to be fixed by double-side adhesive then use glass glue to fix auxiliarly.
Direct fix with glass glue. Before installation, please clean the module surface or make proper polish to ensure the contact surface clean.
The bottom of plastic cement shell to be fixed with screw.
Installation Steps:
Attention
Frequent Troubles and Causes
All the LEDs are off: the general power supply is off.
Partial LEDs are off: The output pole of switch electrical source is wrongly connected or there is open circuit in module cable connection.
All the LED dark: The load LED numbers too much or wrong connection of module pole.
Different LED luminosity: LED load numbers too much.
LED flicker: Cable improper connection; Fuse burned: modules or cable connection point have short circuit.
