Power: The amount of electrical energy consumed by a light source. Units of watts (W)
Power: The amount of electrical energy consumed by a light source. Units of watts (W)
Luminous flux: How much light a light source emits.
Incandescent lamp
1 common type
This type of incandescent lamp is cheap and easy to use, with all kinds of power and appearance. They can be understood as a point source (the light setting in MAX and VIZ is a little light source. It emits yellow and white light around it. From the glass casing of the bulb can be divided into two kinds of bright foam or frosted.
This type of incandescent lamp can be divided into three types of A\ ordinary type (a bit like a pear).
B-ball type (such as the color bulb previously used for the outline of the building)
2 reflective type
There is a certain amount of reflective coating inside the bulb, so that the bulb can push the light forward, so that we can control the beam more conveniently than ordinary incandescent lamps. This kind of light source has floodlight (the ability to diffuse light) , collecting light (concentrating light).
Using the same electrical energy, the reflective bubble (R-type) provides twice the brightness of an ordinary incandescent lamp on an object.
PAR bulbs (parabolic reflectors) provide more precise control of light. They provide up to four times the light of ordinary incandescent lamps, which we often use in compact fixtures and track lighting. In addition, it has thicker protection. Therefore, it is also used in outdoor floodlighting and floodlighting fixtures.
Tungsten halogen lamp (halogen lamp)
Provides bright white light. It has a longer life than incandescent lamps and is much more efficient than conventional incandescent lamps (the amount of light emitted by a light source using 1 watt). It maintains extremely high efficiency throughout the life of the light source. High voltage type (120V) and low voltage (12V) voltage. Low voltage type requires a transformer to gradually reduce the voltage.
1 high pressure type (120V)
A. PAR16\ PAR20\ PAR30 and PAR38 reflective bubbles provide better beam control than conventional incandescent PAR light. There are a variety of narrow
Beam and wide beam selection. Used in track V compact\outdoor spotlight\outdoor floodlights.
B. T-3 double-ended light source can be applied to a variety of lamp holders. The illumination direction of the light source is controlled by the reflector in the lamp. It is suitable for outdoor flooding and wall surface effect lighting.
C. T-4 single-ended light source has a smaller appearance, and the illumination direction of the light source is also controlled by the reflector in the luminaire.
2 low pressure type (12V)
A. MR11 and MR16 low-pressure tungsten halogen lamps provide excellent beam control. There are a variety of beam angles from narrow to wide. The smallest size enables it to be used in smaller tracks, in more compact fixtures. It can also be used in outdoor spotlighting.
B. PAR36 low-pressure tungsten halogen lamp can also provide excellent beam control, especially suitable for longer-distance illumination. With concentrated light/wide beam multiple beam selection, it is used in rail lamps V compact lamps and outdoor lamps.
C. T4 plug-in low-pressure tungsten halogen lamp, commonly known as rice bubble, is used in chandeliers, tungsten halogen desk lamps and other track lamps. The direction of the light source is controlled by the luminaire.
3 fluorescent lights
Only one-fifth to one-third of the energy of an incandescent lamp can emit the same luminous flux, and the life of the incandescent lamp is longer than that of the incandescent lamp. The life expectancy is increased by a factor of ten. The compact fluorescent lamp (energy-saving lamp) can For small luminaires, downlights are the most common home improvement luminaires. They are also used in other embedded and orbital luminaires. Energy-saving lamps with a screw-type base It can directly replace the incandescent light source with conventional lamp holders. Fluorescent lamps can provide a variety of color temperatures. Among them, warm white fluorescent lamps can perfectly replicate the light color of incandescent lamps.
4 high-intensity discharge lamp
High-intensity gas discharge lamps (HID) have a longer life and higher luminous efficiency. High-intensity gas discharge lamps include mercury lamps, metal halide lamps and high-pressure sodium lamps. They are commonly used in outdoor outdoor lighting and landscape lighting in homes.
The distribution box is a massive parameter on the data. Generally, it constitutes a low-voltage forest. According to the electrical wiring, it is required to assemble the switchgear, measuring instrument, protective electrical appliance and auxiliary equipment in a closed or semi-closed metal cabinet or on the screen to form a low-voltage power distribution. box. The circuit can be switched on or off with a manual or automatic switch during normal operation.
Our company's Distribution Boxes are mainly divided into six series(as follow),had exported into global market for many years:
