Downlights generally have a screw cap, which can be directly installed with incandescent lamps or energy-saving lamps. Downlight is a downward lighting lamp 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 because of the setting of lamps and lanterns. This kind of hidden lamp embedded in the ceiling projects all the light downward, which belongs to direct light distribution. Different reflectors, lenses, shutters and bulbs can be used to achieve different lighting effects. Downlight does not occupy space, which can increase the soft atmosphere of the space. If you want to create a warm feeling, you can try to install more downlights to reduce the pressure on the space. Generally used in hotels, families and cafes.
Downlight is generally installed on the ceiling around the bedroom, living room and bathroom. This kind of hidden lamp embedded in the ceiling projects all the light downward, which belongs to direct light distribution. Different reflectors, lenses, shutters and bulbs can be used to achieve different lighting effects. Downlight does not occupy space, which can increase the soft atmosphere of the space. If you want to create a warm feeling, you can try to install more downlights to reduce the pressure on the space.
The main problem of downlight lies in the lamp mouth. The lamp mouth of some inferior brands of downlight is not resistant to high temperature and is easy to deform, which leads to the bulb not being screwed down. Now, all lamps and lanterns must pass 3C certification before they can be sold, and consumers should choose downlights that have passed 3C certification.
There are generally three types of downlights: large (5 inches), medium (4 inches) and small (2.5 inches). There are two types of downlights: horizontal plug and vertical plug. The price of horizontal plug is a little more expensive than vertical plug.
Downlight applicable places: large offices, conference rooms, department stores and specialty stores, laboratories, airports and some civil rooms.
Using downlight as a lamp is convenient to install, does not occupy space, is generous and durable, generally no problem for more than five years, 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 that of incandescent lamp, but its service life is 6 times that of incandescent lamp. Keep the compact design of 175, restrain the existence of lamps and create a bright space.
2. There are two kinds of reflectors: mirror and frosted. A mirror reflector that brings a flicker, and a frosted reflector with moderate brightness harmonize the ceiling.
3. Sliding fixing clips are adopted, which is convenient for construction. It can be installed on ceilings with different thicknesses from 3 mm to 25 mm, and the lamps can be easily disassembled during maintenance.
There are three kinds of lamps to choose from. There are 3 models of 2,700k, 4,000k and 6,700k, and the most suitable lamp can be selected according to different purposes.
Spotlights can be placed around the ceiling or on the upper part of furniture, inside walls, dados or skirting lines. The light shines directly on the furniture and utensils that need to be emphasized, so as to highlight the subjective aesthetic function and achieve the artistic effect of outstanding focus, unique environment, rich levels, rich atmosphere and colorful colors. The spotlights are soft and elegant, which can not only play a leading role in overall lighting, but also play a role in local lighting and foil atmosphere.
1, energy saving: the power consumption of LED lamps with the same power is only 10% of that of incandescent lamps, which is more energy-saving than fluorescent lamps.
2. Long service life: LED lamp beads can work for 50,000 hours, which is longer than fluorescent lamps and incandescent lamps.
3, dimmable: the previous dimmer has always been aimed at incandescent lamps, and the incandescent lamps are red when dimming; The ugly dimmer of fluorescent lamp is the main reason why the dimming technology has not developed for many years; LED can be dimmed again, and the light and dark are the same color (the color temperature is basically unchanged), which is obviously better than incandescent lamp dimming.
4, can be frequently switched on and off: the life of LED is calculated according to the lighting time, even if it is switched on and off for thousands of times per second, it will not affect the life of LED. In occasions such as decoration that need to be switched on and off frequently, LED lights have absolute advantages.
5. Rich colors: positive white light, warm white light, red, green, blue and other colors. Both small colored lights and neon lights used to decorate the headlights in the living room are very bright.
6. Low calorific value: Like spotlights, many 220V incandescent lamps will break down after a few days of heating. 12V halogen spotlight is lower in calorific value than 220V spotlight, but its brightness can't reach the nominal value due to insufficient transformer power. With LED spotlights, you can work for a long time without a transformer.
Downlight and spotlight are confused by many people. I don't know what's the difference between these two lamps, where they should be used at home, and what's the difference in application effect.
Simply put, downlight is a kind of lamp that focuses more light than ordinary surface mount lamp, and is generally used for general lighting or auxiliary lighting.
A spotlight is a highly concentrated lamp, and its light irradiation can specify a specific target. It is mainly used for special lighting, such as emphasizing a place with great taste or originality.
We distinguish downlights from spotlights from these aspects.
1. From the light source, downlights can be equipped with incandescent bulbs or energy-saving lamps. Yellow when incandescent lamps are installed. When installing energy-saving lamps, the type of bulbs can be white or yellow. The light source direction of the ceiling downlight cannot be adjusted. General household spotlights use quartz bulbs or beads. Of course, quartz bulbs are not necessary for large spotlights. 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 needs more than 150mm to be installed. Of course, downlights are also available externally. It is a good choice to install downlights in areas without ceiling lamps or chandeliers. The light is softer than spotlights. Spotlight can generally be divided into track type, point hanging type and embedded type. Spotlights are generally equipped with transformers, and some are without transformers. Embedded spotlights can be installed on the ceiling. Spotlights are mainly used in places that need to be emphasized or expressed, such as TV walls, hanging pictures, ornaments and so on. , can play a rhyming role and enhance the effect.
3. From the price point of view, spotlights are more expensive.
It should be noted that spotlights can't be used to illuminate woolen goods at close range, nor can there be flammable obstacles at close range, otherwise it will easily cause fire. Although the spotlight consumes a lot of electricity, it has a completely different embellishment effect in the appropriate position. Spotlights and colored cups are decorated with special flavor.
4. From the installation position.
Downlight is a downward lighting lamp 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 because of the setting of lamps and lanterns. Downlight does not occupy space, which can increase the soft atmosphere of the space. If you want to create a warm feeling, try installing more downlights.
Spotlight is mainly installed around the ceiling or the upper part of furniture, or placed on the wall, dado or baseboard. Used to highlight the aesthetic function, highlight the sense of hierarchy and create an atmosphere, which can not only play a leading role in overall lighting, but also play a role in local lighting.
Matters needing attention
First, check whether the product is in good condition immediately after opening the downlight package. Faults caused by non-human factors or requirements specified in the manual can be returned to the retailer or directly to the manufacturer for replacement.
Second, cut off the power supply before installation to ensure that the switch is in a closed state to prevent electric shock. Please don't touch the surface of the lamp after the lighting is on. This lamp should be avoided to be installed in heat sources and places with hot steam and corrosive gases, so as not to affect its service life.
Third, please confirm the applicable power supply according to the installed quantity before use. This product is for indoor use only. Please pay attention to waterproof outdoors. Before installation, ensure that the installation position can bear 10 times the weight of this product.
Fourth, the lamp cup powered by high voltage (1 10V/220V) is not suitable for working in the state of frequent power on and off, which will affect its service life.
Five, installed in a flat place without vibration, swing, no fire hazards, pay attention to avoid falling, hard object collision, knocking.
6. If the downlight is stopped for a long time, it should be stored in a cool, dry and clean environment, and it is forbidden to store and use it in damp, high temperature or inflammable and explosive places.
process flow
1. cleaning: clean the PCB or LED bracket with ultrasonic wave and dry it.
2. Mounting: After the bottom electrode of the LED die (wafer) is prepared with silver glue, it is expanded, and the expanded die (wafer) is placed on the wafer stage. Under the microscope, the dies are mounted on the corresponding pads of PCB or LED bracket one by one with a crystal stylus, and then the silver paste is sintered and solidified.
3. Bonding: Connect the electrode to the LED die with aluminum wire or gold wire welder as the lead wire for current injection. When LED is directly mounted on PCB, aluminum wire welder is generally used.
4. Packaging: epoxy resin is used to protect LED chips and bonding wires through dispensing. Dispensing glue on PCB has strict requirements on the shape of cured glue, which is directly related to the brightness of finished backlight. The process will also undertake the task of lighting phosphor (white 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: Punching various diffusion films and reflective films needed for backlight with a punch.
7. Assembly: According to the requirements of the drawings, manually install various materials of the backlight in the correct position.
8. Test: Check whether the photoelectric parameters and light uniformity of the backlight are good.
9. Packaging: The finished products are packaged and put into storage as required.
