LED strip SMD 5050 12V 14.4W/m purple 60LED/m IP20 5m

LED Strip - Construction

The strip uses SMD technology with LEDs in a 5050 package. The underside has factory-applied double-sided adhesive tape to aid installation on a suitably prepared surface.

Control of LED strip

The strip can be powered directly from a suitable 12V power supply. An optional PWM controller enables brightness adjustment.

Important information

The stated power is a rated or theoretical value based on the parameters of the components used. Actual power consumption may be lower due to component tolerances, voltage drop and operating conditions.

Power and installation

The strip does not require an additional power-injection point when its length does not exceed 5m. Above this length, consider starting the next separately powered run, supplying the run at its far end, or adding another power point after the indicated length.

The 5m value is based on the electrical properties of the strip PCB. It indicates the length at which supply-voltage drop should not cause a noticeable reduction in LED brightness along the length of strip. Above this length, a brightness difference may become visible. If it remains acceptable to the end customer, the final power-feed arrangement is the responsibility of the installation designer or user.

Light emitted by LED strip

A single-color mono LED strip emits purple light. It is a single-channel light source — all LEDs operate together, without independent color mixing. The mono LED strip family includes, among others, red, green, blue, violet, pink, amber, yellow, UV, and near-UV models.

The color of the emitted light depends on the spectral distribution of the LED radiation, characterized among other parameters by its dominant or peak wavelength. Red and amber belong to the long-wavelength region of the visible spectrum, yellow and green occupy its middle range, while blue and violet are located toward the short-wavelength, higher-frequency end. UV radiation lies outside the visible spectrum, whereas near-UV is located close to its boundary and may be perceived as deep violet while strongly exciting fluorescence in certain materials.

Red, green, and blue are the primary colors of the additive RGB color model. In multi-channel systems, mixing them makes it possible to produce secondary colors — for example, yellow from red and green, and magenta or pink from red and blue. This does not mean, however, that a single-color yellow, amber, or violet strip mixes RGB channels. In a mono strip, the specified color is produced directly by the LEDs used or by their specifically engineered spectral characteristics. Pink and magenta are non-spectral colors — they do not correspond to a single wavelength, but rather to a specific combination of spectral components. Spectral violet, on the other hand, can be produced directly in the short-wavelength region of visible light.

Perceived brightness depends not only on radiant power, but also on the sensitivity of human vision. Under photopic, or daylight, vision conditions, maximum sensitivity occurs near 555 nm. For this reason, yellow-green and green light may appear particularly intense at the same optical power. Under scotopic, or night-vision, conditions occurring at very low illumination levels, peak sensitivity shifts toward approximately 507 nm, in the blue-green region. Red and amber then become relatively less visible.

Blue light has a very distinctive appearance and is highly effective at attracting attention, particularly in large, simple shapes viewed from a greater distance. At low luminance, however, small blue elements may appear less sharp, slightly blurred, or surrounded by a visible halo. This results, among other factors, from the chromatic aberration of the human eye and reduced visual acuity in the short-wavelength region of the spectrum. For this reason, blue is not the best choice for small lettering, thin outlines, or complex symbols where maximum sharpness and detail legibility are critical. It performs very well, however, as a strong signaling and decorative accent.

For static operation, a mono LED strip does not require a controller — it only needs to be connected to a correctly selected power supply. Light intensity adjustment requires a compatible single-channel LED dimmer or controller, most commonly using PWM modulation. In the case of UV and near-UV strips, the model should be selected primarily according to its actual wavelength and intended application, because apparent brightness is not a reliable measure of radiant power.

LED strip - product overview

The strip operates at 12V and has a density of 60LED/m with an IP20 ingress-protection rating.

Sales unit of led strip

The sales unit includes a factory-prepared reel of LED strip with a length of 5m.

LED strip - power supply selection

The strip requires a power supply with an output voltage of 12V. Guidance: select a power supply with an optimum 30% power reserve above the LED strip demand.

Purple LED strip 300LED SMD 5050 – premium accent lighting

Choose the purple LED strip 300LED SMD 5050 when you want a bold, designer glow with reliable performance.

Uses for a purple LED strip for aluminium profiles

A purple LED strip for aluminium profiles is perfect for modern interiors and commercial spaces. Use it to highlight shapes, add mood, and guide attention. Violet light works great in creative studios, gaming rooms, bars, and brand displays.

• Furniture, shelves, niches, and under-cabinet accents
• Ceilings, coves, and architectural lines
• Signage, exhibitions, and retail displays
• Aluminium profiles for cleaner mounting and better cooling

Power supply, safety, and voltage drop

Use a constant-voltage power supply matched to the total wattage. Add a 20–30% reserve for stable work. Choose models with protections like OVP, OCP, SCP, and OTP. Active PFC can improve efficiency and operating stability.

For longer runs, use power injection to avoid dimming. Feed power about every 5 m for 12V systems, or every 10 m for 24V systems. Use a star wiring layout and proper cable thickness.

Installation and finishing

Mount the strip on a clean, degreased surface. For the best effect, install it in an aluminium profile with a diffuser. You can connect sections by soldering or quality connectors. Always cut only at the marked points.

FAQ

• Which power supply should I choose? Sum the wattage of all sections and add 20–30% headroom.
• When do I need power injection? For long runs or high LED density, to keep brightness even.
• Can I cut and reconnect the strip? Yes, cut at marked points and reconnect with solder or connectors.
