50W LED Floodlights

LED floodlights with a power of 50 W are invariably used in the construction industry, design and advertising, when illuminating works of art and architectural elements. A high degree of their reliability and resistance to moisture ensure their use when organizing backlighting even in an aqueous environment, not to mention everyday issues.

LED floodlights with a power of 50 W are light sources manufactured to apply light energy in specific places. The light emitted by them is given the appropriate spatial angle required at the place of use by means of a special mirror device. They are characterized not only by a high level of luminous flux (they shine brightly), but also by durability.

One of the features of the device is the presence of a reflector in it, which concentrates the light in the right place. The shapes of the reflectors are determined by the peculiarities of the place where the searchlights are used, and special mirrors are used to increase the range of propagation of the rays. Such a structure is typical, for example, in border devices. In this case, to create a powerful beam of light, the angles of its scattering lead to a given ratio with other design parameters of the product. The uniformity of the luminous flux emitted by LEDs depends on the reflector.

The versatility of products is determined by the specifics of the places of use and protection standards, which have their own markings and parameters:

• IP44 - for indoor lighting;
• IP65 - outdoor options;
• IP67 - for ground use;
• IP68 - for underwater use.

Other features.

1. The presence of special drivers for organizing power supply. At the same time, it is taken into account that LED-based drivers must withstand outdoor temperatures from -40 to +40 in dry or humid air (full protection - at the IP 68 level, from dirt, as well as when placed in reservoirs at depths of more than 1 m ).
2. Exceptional tightness of the power unit. For this, the entire electronic part is filled with a compound, and the power part is mounted with a silicone seal.
3. The use of optical devices to form the required angles of the diode glow.
4. The presence of special radiators for good heat dissipation.
5. Using a reflector (reflector) that reflects the light flux into the source area with the least scattering. Here, parabolic or hyperbolic types of mirrors are used.
6. The presence of terminals for connecting the power section and the light module.
7. Application of special protective glass.

Of the advantages of the device, we highlight:

• obtaining a high degree of brightness;
• no overheating of circuit elements;
• the presence of a high level of resistance to mechanical stress;
• long service life;
• low level of power consumption;
• environmental harmlessness, including during disposal;
• the formation of a concentrated light beam.

Minuses:

• high price tag;
• the need for a power supply module;
• the complexity of replacing failed LEDs.

The main characteristics of the product include:

• running standard size 259x190x32 mm;
• glow angles;
• the value of the light supply index is more than 85 ra;
• power level 50-50.6 watts;
• light flux level - up to 3450 lm;
• average weight - 1.2 kg.

Diode floodlights are classified according to various criteria.

1. For internal use.
2. For street lighting.

Underwater devices are used to illuminate reservoirs, and the main indicators here are: the power of the diodes, the greatest depth of the device, proper adherence to the accepted standard values ​​for the level of moisture resistance.

With soil options, the devices are located in the ground or in road elements. Like other types of devices, they are equipped with reliable diodes (SMD 5050, SMD 5730). They are selected according to the power, the degree of strength of the protective glass and the degree of protection against dust and moisture.

For ordinary street devices, the relevant parameters are: the angle of beam propagation, power and degree of protection from dirt and moisture. All outdoor products are designed to operate in unstable electrical conditions.

By the strength of the radiation, the devices produce:

• low-emitting - up to 1500 lm;
• medium-emitting - up to 10,000 lm;
• highly emitting - from 10 klm.

By radiation colors:

• white;
• close to white;
• multicolor (rgb);
• to illuminate landscapes;
• for accented design;
• for track lights;
• for decorative needs;
• for illumination purposes;
• in industrial execution;
• for facade decoration;
• to decorate water spaces.

At the same time, there are various temperature modes for the operation of products:

• 2800 k - soft, yellowish (warm color);
• 4200 k - soft, typical white;
• 6000 k - coldish white.

There are devices:

• monochrome type;
• matrix;
• linear;
• full color.

The first type of device is used to create an accentuated type of lighting. Thus, the IntiLINE series floodlights include a number of subsections, where they can be adjusted autonomously. The body of the product is made of aluminum coated with a special powder composition. Average power - 4953 W.

Matrix devices provide for the presence of voltage stabilizers. Therefore, the product is capable of functioning in a certain voltage register - 85-265 V. It is powered by a three-core wire made by Chip On Board (chip on board), which reduces the dimensions of the diode unit. Due to this, there is an increase in the duration of the operation of the crystals and an improvement in the quality of illumination.

Devices of the linear type have positively proven themselves when organizing the illumination of the facades of buildings at various levels, when it is necessary to supply light downward. Products are produced with different types of filling and a different number of diodes. The types of used optics also vary here.

Full-color devices have shown themselves well when organizing all kinds of colorful backlights. For example, the DDU01 FL24-LED product is regulated using various elements responsible for the brightness and color of the diode glow. In practice, a distinction is also made between rechargeable and portable versions of 50W floodlights. In this case, the area covered with light and the quality parameters of LEDs are of great importance.

Repair of LED floodlights seems to be advisable, but only in those cases when they use spare elements coordinated with each other (in terms of volt-ampere parameters). Mistakes in their selection can be expensive - the payment for repairing the product reaches 400 rubles.

Matrices (light sources) and drivers (power supplies) are usually subject to replacement. Both of these elements, as a rule, cannot be disassembled, and in case of failure they must be replaced separately or in pairs. The number of matrices and drivers in a product can be from 1 to 4. Inexpensive and poorly executed devices break down more often and faster.

The device is resistant to extreme climatic conditions.

The main and simplest selection criteria:

• cleanliness, dryness and serviceability of the packaging;
• barcode display;
• availability of instructional documents;
• indication of the type of product and its manufacturer without errors;
• parameters, functions and current values ​​can be found on the packaging, in the instruction documents or in the data sheet.

Next, we check the technical parameters: - power, overall dimensions and weight of the product, compliance with the level of protection of the case in relation to the conditions of use of the device. We are dealing with additional functions that expand the possibilities of using the device (motion and light sensors, the ability to adjust the brightness, etc.).

In the process of connecting the device, it is important to follow the safety rules.

1. Regardless of the power supply parameters of the mounted device (220 V or 12 V), before starting work, you should definitely not wet your hands.
2. Do not handle electrical equipment with wet or sweaty hands.
3. We do not recommend starting work with outdoor devices in wet or cloudy weather.
4. In the course of work, do not forget to disconnect the circuit from the power supply, in order to avoid electric shock.
5. First, you should measure the voltage in the network and make sure that its value is no more than 220 V (permissible deviations are 5-6%).
6. Avoid placing the product tightly with low-power appliances.
7. Do not place or use any chemicals near the LED lights.
8. If you find any malfunctions in the operation of the led floodlight, immediately disconnect it from the mains. Failures can occur due to a malfunction of the matrix itself, individual diodes or voltage surges.

The installation work of the device is usually phased in nature:

• search for the installation site;
• preparation of tools and materials;
• direct connection.

We define the area for lighting. We select a place so that the light hits exactly the intended area. It is better to draw up a diagram or sketch beforehand. It is clear that the power supplies of the device must be nearby. It is extremely important that the fixing brackets sit firmly on the wall or on the selected object. The devices are attached to ceilings, supports, walls, but the main requirement will be a smooth mounting surface. The mounting height will depend on the dimensions, power of the device and the illuminated area. Small devices are usually mounted at a height of no more than 16 m.

At the second stage, you will need:

• side cutters;
• office knife or special wire stripper;
• soldering iron and accessories;
• insulating tape;
• screwdriver.

Read the instructions carefully. If there is nothing specified about the polarity, then during installation it can be ignored. To connect the floodlight, use a copper or other conductor resistant to high temperature values ​​(up to 160 ° C). It is not always necessary to ground the circuit, so the yellow-green wire can simply be reliably insulated and hidden in the rear section of the device. The specificity of the connection may well depend on the type of modification (operates on direct or alternating current). In the first case, you can use a household rectifier.

Before installation, examine the body of the product (make sure it is not damaged). Next, you need to free the terminal block in order to gain access to the terminals and grounding assemblies. Then remove the stuffing box entry and de-energize the line by turning off the power supply from the general switchboard.

Mount the cover in the free space - it will protect the wiring from water. Position the device by lightly installing the screws and screws. Remove the wires from the box and connect to the required (according to the wiring diagram) ends. Solder the connections securely. Next, isolate the joints, hide them inside the terminal box, which then close the lid by screwing it in with bolts. Fasten the screws to the device to firmly install it.
