Whether to use downlights or spotlights around the ceiling in the living room has its own characteristics and applications
Downlights generally have a screw cap that can be directly installed with incandescent lamps or energy-saving lamps. Light fixtures. Downlights are downlight lighting fixtures that are embedded in the ceiling. Its biggest feature is that it can maintain the overall unity and perfection of architectural decoration, and will not destroy the perfect unity of ceiling art due to the setting of lamps. This kind of recessed lamp is embedded in the ceiling, and all the light is projected downward, which is a direct light distribution. Different reflectors, lenses, blinds, and light bulbs can be used to achieve different light effects. Downlights do not take up space and can add a soft atmosphere to the space. If you want to create a warm feeling, you can try installing multiple downlights to reduce the pressure of the space. Generally used in hotels, homes, and cafes.
Downlights are generally installed on the surrounding ceilings of bedrooms, living rooms, and bathrooms. This kind of recessed lamp is embedded in the ceiling, and all the light is projected downward, which is a direct light distribution. Different reflectors, lenses, blinds, and light bulbs can be used to achieve different light effects. Downlights do not take up space and can add a soft atmosphere to the space. If you want to create a warm feeling, you can try installing multiple downlights to reduce the pressure of the space.
The main problem with downlights is the lamp socket. The lamp sockets of some off-brand downlights are not resistant to high temperatures and are easily deformed, causing the bulb to fail to be unscrewed. Now, all lamps can only be sold after passing 3C certification. Consumers must choose downlights that have passed 3C certification
Downlights generally come in three types: large (5 inches), medium (4 inches) and small (2.5 inches). . There are two types of downlights: horizontal ones and vertical ones. Horizontal ones are slightly more expensive than vertical ones.
Suitable places for downlights: large offices, conference rooms, department stores and specialty stores, laboratories, airports and some residential buildings.
Using downlights as lamps is easy to install, does not take up space, is generous and durable, and can usually be used for more than five years without any problems, and the style is not easy to change. The price is also cheap.
1. Compact and high luminous flux. The power consumption is 1/3 of incandescent lamps, but the lifespan is 6 times that of incandescent lamps. The size maintains a compact design of 175, suppressing the presence of lamps and creating a bright space.
2. There are two types of reflective plates, mirror and frosted. The mirror reflective board brings a sense of sparkle, and moderates the brightness to harmonize with the frosted reflective board on the ceiling.
3. The sliding fixing card is used for convenient construction. It can be installed on ceilings with different thicknesses from 3mm to 25mm, and the lamp can be easily removed during maintenance.
4. There are three types of lamps to choose from. There are three types: 2,700k, 4,000k, and 6,700k. You can choose the most suitable lamp according to different uses.
Spotlights can be placed around the ceiling or on top of furniture, in walls, dados or skirtings. The light directly shines on the household items that need to be emphasized to highlight the subjective aesthetic effect and achieve the artistic effect of highlighted key points, unique environment, rich layers, rich atmosphere, and colorfulness. The spotlights are soft, graceful and luxurious. They can not only play a leading role in the overall lighting, but also provide local lighting to enhance the atmosphere.
1. Energy saving: LED lights with the same power consume only 10% of the power of incandescent lamps, which is more energy-saving than fluorescent lamps.
2. Long life: LED lamp beads can work for 50,000 hours, which is longer than fluorescent lamps and incandescent lamps.
3. Dimmable: The previous dimmers have always been for incandescent lamps. When the incandescent lamp is dimmed, the light will glow red; it is difficult to see a fluorescent lamp dimmer. This is a dimming technology that has been around for many years. The main reason for the lack of development; LED can be dimmed again, and it has the same color whether it is bright or dark light (the color temperature is basically unchanged), which is obviously better than the dimming of incandescent lamps.
4. Can be switched on and off frequently: The life of the LED is calculated based on the time it is lit. Even if it is switched on and off thousands of times per second, it will not affect the life of the LED. In decoration and other occasions that need to be turned on and off frequently, LED lights There is an absolute advantage.
5. Rich colors: There are various colors such as pure white light, warm white light, red, green, blue, etc., whether it is a small colorful light used for decoration next to the headlight in the living room or a neon light, it is very bright.
6. Low calorific value: Like spotlights, many 220V incandescent lamps break down within a few days because they generate heat. Although the calorific value of 12V halogen spotlights is lower than that of 220V spotlights, their brightness does not reach the nominal value due to insufficient power of the transformer.
With LED spotlights, you can work for a long time without a transformer.
Many people are confused between downlights and spotlights. They don’t know the difference between these two types of lamps, where they should be applied in the home, and what the effects of their application are.
To put it simply, downlights are lamps that are more concentrating than ordinary surface-mounted lamps and are generally used for general lighting or auxiliary lighting.
Spotlight is a highly concentrated light fixture, and its light irradiation has a specific target that can be specified. It is mainly used for special lighting, such as emphasizing a very interesting or innovative place.
We distinguish between downlights and spotlights from these aspects.
1. From the light source point of view, downlights can be equipped with incandescent bulbs or energy-saving lamps. When an incandescent lamp is installed, the light is yellow. When installing energy-saving lamps, depending on the type of bulb, it can be white light or yellow light. The light source direction of the ceiling downlight cannot be adjusted. Generally, household spotlights use quartz bulbs or lamp beads. Of course, large spotlights do not necessarily use quartz bulbs. Quartz bulbs only have yellow light. Moreover, the light source direction of general spotlights can be adjusted freely.
2. From the application position, downlights are generally installed in the ceiling. Generally, the ceiling must be above 150mm before they can be installed. Of course, there are also external downlights. It is a good choice to install downlights in areas without ceiling lights or chandeliers. The light should be softer than spotlights. Spotlights can generally be divided into track type, point-hung type and built-in type. Spotlights usually come with a transformer, but there are also ones without a transformer. Recessed spotlights can be installed in the ceiling. Spotlights are mainly used for places that need to be emphasized or expressed, such as TV walls, hanging paintings, accessories, etc. They can create aura to enhance the effect.
3. In terms of price, spotlights are more expensive for the same grade.
It should be noted that spotlights generally cannot be used to illuminate woolen fabrics at close range, nor can there be flammable obstacles at close range, otherwise it may easily cause a fire. Although spotlights consume a lot of power, the effect of embellishment in the appropriate position is very different. Spotlights and colorful lamp cups add a unique touch of decoration.
4. From the installation position
Downlight is a downlight lighting fixture embedded in the ceiling. Its biggest feature is that it can maintain the overall unity and perfection of architectural decoration, and will not destroy the perfect unity of ceiling art due to the setting of lamps. Downlights do not take up space and can add a soft atmosphere to the space. If you want to create a warm feeling, you can try installing multiple downlights.
Spotlights are mainly installed around the ceiling or on top of the furniture, or placed in the wall, dado or skirting. It is used to highlight the aesthetic effect, highlight the sense of layering, and create an atmosphere. It can not only play a leading role in overall lighting, but also provide local lighting.
Notes
1. After opening the downlight packaging, you should immediately check whether the product is intact. If a malfunction occurs that is not caused by human factors or does not meet the requirements specified in the manual, it can be returned to the retailer or directly to the manufacturer for replacement.
2. Cut off the power before installation and ensure that the switch is closed to prevent electric shock. After the lighting is lit, do not touch the surface of the lamp with your hands. This lamp should avoid being installed in places with heat sources, hot steam, and corrosive gases to avoid affecting its lifespan.
3. Before use, please confirm the applicable power supply according to the installation quantity. This product is only for indoor use. When using it outdoors, please pay attention to waterproof installation and ensure that the installation location can withstand 10 times the weight of the product.
4. The product uses a high-voltage (110V/220V) power supply lamp cup, which should not be operated under frequent power on and off, as this will affect its lifespan.
5. Install in a flat place with no vibration, no swing, and no fire hazard. Be careful to avoid falling from high altitude, collision with hard objects, and knocking.
6. If out of service for a long time, the downlight should be stored in a cool, dry and clean environment. It is prohibited to store and use it in humid, high temperature or flammable and explosive places.
Process flow
1. Cleaning: Use ultrasonic cleaning to clean the PCB or LED bracket and dry it.
2. Mounting: Prepare the bottom electrode of the LED tube core (large wafer) with silver glue and expand it. Place the expanded tube core (large wafer) on the spindle table and examine it under the microscope. Use a crystal pen to install the tube cores one by one on the corresponding pads of the PCB or LED bracket, and then sinter to solidify the silver glue.
3. Pressure welding: Use an aluminum wire or gold wire welder to connect the electrode to the LED die as a lead for current injection. If the LED is directly mounted on the PCB, an aluminum wire welding machine is generally used.
4. Encapsulation: Protect the LED die and welding wires with epoxy by dispensing glue. Dispensing glue on the PCB board has strict requirements on the shape of the cured glue, which is directly related to the brightness of the finished backlight. This process will also undertake the task of dotting phosphor (white light LED).
5. Welding: If the backlight is SMD-LED or other packaged LED, the LED needs to be welded to the PCB before the assembly process.
6. Film cutting: Use a punch to die-cut various diffusion films, reflective films, etc. required for backlight sources.
7. Assembly: According to the drawing requirements, manually install the various materials of the backlight in the correct position.
8. Test: Check whether the backlight photoelectric parameters and light uniformity are good.
9. Packaging: Pack and store the finished products as required.
