Description
Technical field
The cylinder lamp structure that it is light source that the utility model relates to a kind of LED module is used for substituting conventional embedded fluorescent lamp Down lamp, belongs to the LED technical field of semiconductor illumination.
Background technology
The LED led technology starts from late 1960s, through semicentennial developing rapidly, led light source, particularly high-power highlighted led light source, with its light efficiency height, little, the long service life of volume, and many-sided advantage such as environmental protection and energy saving, occupied critical positions in the lighting source field, and still in continuing to develop rapidly.
The light fixture that generally uses adopts fluorescent lamp as light source more at present.The general power consumption of this fluorescent lamp is higher, lamp tube service life short, and photochromic soft inadequately, and flicker is arranged, and trunon delay time is long.Use mercury can endanger environment.
LEDLight Emitting Diode claims light emitting diode again, and they utilize the solid semiconductor chip as luminescent material, and when two ends add appropriate voltage, the carrier in the semiconductor takes place compound, emits superfluous energy and causes that photo emissions produces visible light.The led light source luminous efficiency is high and monochromaticjty its light is good, spectrum is narrow, need not to filter and can directly send coloured visible light.Under the situation of the same less illuminating effect of power consumption, power consumption is 1/8th of incandescent lamp bulb, 1/2nd of fluorescent tube.Long service life can reach 100,000 hours.Security reliability is strong, and caloric value is low, and non-thermal radiation belongs to cold light source, can safe touch and can accurately control light type and lighting angle, and photochromic soft, the material that free from glare, not mercurous, sodium element etc. may health risks.The controllability height, built-in microprocessing systems can be controlled luminous intensity, regulates illumination mode, presents bright and colourful seven-colour-light coloured silk, realizes that light combines with artistic.
The utility model content
The purpose of this utility model is improved at existing fluorescent lamp Down lamp above shortcomings exactly, and a kind of good heat dissipation effect is provided, and interchangeability is strong, structure uniqueness, LED module Down lamp easy to maintenance.
The purpose of this utility model is achieved in that LED module Down lamp, comprise lamp ring 1, Lamp cup 2, LED module 3, radiating block 4, mounting spring 5, Wire fastener 6, it is characterized in that described radiating block 4 inside top are planar structure, the outside is provided with the heat radiation rib, LED module 3 bottoms scribble conduction estersil, be fastened on the inside top of radiating block 4, LED module 3 is connected with the lead driver of fixing by Wire fastener 6, the light-emitting area of LED module places in the Lamp cup 2, and the bottom surface of Lamp cup 2 is provided with air-vent.
Described radiating block 4 is the aluminium alloy compression casting structure, and the heat radiation rib on the radiating block is a parallel strip or radial, is arcuation and distributes.
Described Lamp cup 2 surfaces are paraboloidal or taper shape or rectangular pyramid shape.
Described mounting spring 5 is the lamp-mounting structure of metal spring or metal and plastics combination.
Described lamp ring 1 is metallic article or plastic products.
The utility model is rational in infrastructure simple, and good integrity is manufactured, the processing assembling is convenient.Do not need dismounting just can be directly installed on the ceiling when mounted, and excellent interchangeability.Radiating block 4 is the aluminium alloy compression casting moulding, and simultaneously top and the side of radiating block 4 are provided with the heat radiation rib, and the heat radiation rib can be parallel strip, radial or other shape, and according to the distribution of thermograde, different height presents the arcuation distribution.Take out of by the heat that cross-ventilation method, heat radiation will be dispelled the heat on the rib.LED module 3 bottoms scribble conduction estersil, and directly radiating block 4 contacts more help heat transmission, distribute.Air-vent is adopted in the bottom surface of Lamp cup 2, in time replenishes the air of lower temperature to LED module 3, has guaranteed the required operating ambient temperature of led light source operate as normal, thereby has prolonged the service life of LED light fixture.LED module 3 can adopt different sizes, the module of power, to be suitable for different power requirement LED module Down lamps.LED module 3, Lamp cup 2 are formed reflective optical system, the light that LED module 3 produces are redistributed, to improve the light efficiency of whole light fixture.
