Yunfu LED downlight manufacturer: LED tube light let indoor lighting brighter and healthier
within the LED tube light is a kind of embedded in the ceiling light beam type of lighting lamps and lanterns. Belong to the directional lighting lamps and lanterns, can only by the light of the opposite, beam Angle belongs to the condenser, the light is relatively concentrated, comparative and intense light and shade. LED tube lamps and lanterns has the following advantages: energy saving, low carbon, long life, good color rendering, fast response, no ultraviolet and infrared ray radiation, illumination without heat, no damage to be according to the content. LED spotlights, beautiful light design, installation to keep building decoration of the overall unity and perfect, hidden inside building decoration, light source the light source is not exposed, no glare, increase space downy atmosphere.
from traditional tube light to LED tube light, tube light source are continually replaced by new ones, from fluorescent lights to the straw hat lamp beads, high power commercial ceiling lamps bead, and then to today's patch lamp bead ( SMD) And the LED integrated light source ( COB） , the development of LED tube light is a step in a year.
LED spotlights on the light source, there are three main types:
the first: patch lamp bead ( SMD) , using more than middle and small power LED such as 5630, 5730, 4040, 7070, 1 w, and the following leds, stable and mature technology, high brightness, the light is downy, single low power, low calorific value, good heat dissipation, long life, light color evenly, can meet the demand of LED tube light full plate, realize no dark space.
the second: high-power lamp bead, adopts various power in 1 ~ 3 w leds. Third:
(integrated light source COB） , deep cover type, has the anti glare, brightness, illumination, strength, high photosynthetic efficiency, high color rendering index, etc.
LED spotlights, optical design
patch lamp bead ( SMD) :
the patch lamp bead ( SMD) As a canister light source, because of the large number of leds, can be full of the light source cavity, as much as possible so we can make the LED work into the heat distribution of more widely, facilitate heat dissipation, but also to avoid local overheating temperature. Distribution is more dispersed, because LED light source to the smooth surface can be designed to be small, it can achieve the result of uniform light, so the patch lamp bead ( SMD) The canister light can will have to lower the height of the canister light design.
(integrated light source COB） :
the integrated light source ( COB） As a canister light source, because already own circuit boards, integrated light source when use only need to fixed, so compared with the patch lamp bead ( SMD) To save the cost of aluminum plate and the cost of the tiles. Because of the integrated light sources ( COB） A larger power, LED at work, heat source is concentrated, so it is more on cooling design requirements; Second, the smooth surface of small integrated light source, in order to avoid the light spot on the smooth tube light, usually need to be integrated light source to the smooth surface distance is larger, which requires the reflectors height is higher, so the integration of the canister light height of light source is higher, the volume of the lamps and lanterns is relatively large. In order to reduce the height of the entire canister light, can make use of high reflectivity reflector to reduce the height of the reflectors.
the LED downlight categories:
1, the installation method: embedded downlight and surface mounted type canister light
2, location: home canister light and engineering canister light. People mainly is 2. 5 'and 3. 5 'small size, mainly used in the family; 4 ', 6 ', 8 'belongs to the public, normally apply to hotels, office buildings and public places.
3, function: monochrome canister light and light tube light.
are present in just about every facet of modern life.
