Description
Technical field
The present invention relates to the structure that a kind of LED is the light source module, be used for substituting conventional fluorescent light, be particularly useful for embedded, ceiling type Down lamp light fixture, belong to the LED technical field of semiconductor illumination.
Background technology
LED (light emitting diode) 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.
LED (Light Emitting Diode), claim light emitting diode again, they utilize the solid semiconductor chip as luminescent material, when two ends add appropriate voltage, 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.
Existing led light source has solved the some shortcomings that existing use conventional fluorescent exists, but owing to adopt low power LED as light source, its luminous flux is obviously not enough, owing to be enclosed in the glass tube, weak heat-dissipating, inconvenient maintenance, and, shortened its service life on the contrary owing to adopt many series circuit fault rates high.In order to improve the weak point of above-mentioned LED Down lamp, patent of the present invention has proposed the Novel LED light source module that a kind of novel structure, good illumination effect can solve existing LED straight tube light source the problems referred to above again.
Summary of the invention
Purpose of the present invention is improved at existing low-power LED light source and fluorescent lamp above shortcomings exactly, and a kind of good heat dissipation effect is provided, and interchangeability is strong, structure uniqueness, Novel LED light source module easy to maintenance.
The object of the present invention is achieved like this: the Novel LED light source module, comprise diffuser 1, Lamp cup 2, led light source 3, sponge adhesive tape 4, flexible PCB plate 5, radiating block 6, it is characterized in that diffuser 1, Lamp cup 2, sponge adhesive tape 4, radiating block 6 is installed and is connected and composed airtight cavity, radiating block 6 adopts aluminium alloy extruded one-tenth slab construction, the outside is provided with the heat radiation rib, plurality of LEDs light source 3 is welded on the radiating block 6 inside top flexible PCB plates 5 by scolding tin, Lamp cup 2 adopts the minute surface aluminium sheet of high reflectance to make, be fastened on the radiating block 6 by connector, sponge adhesive tape 4 is arranged between Lamp cup and the radiating block 6, diffuser 1 adopts the transparent glass or the prism PMMA of high transmission rate, is installed in the Lamp cup bottom.
Described heat radiation rib is a parallel strip or radial.
Described pcb board is pasted or screw is fastened on the radiating block.
Cylindrical square or the conical or rectangular pyramid shape or prismatic of described Lamp cup.
Novel structure of the present invention, rationally simple, good integrity is manufactured, the processing assembling is convenient.The Novel LED light source module can be used as the light source of light fixture such as Down lamp, and is low in energy consumption and photochromic soft, as light source, can use various monochromatic light with great power LED, or adopts the RGB three-color light source.Do not need dismounting just can directly install during installation, also can be made into the light belt, combination lamp of various moulding etc., interchangeability is good.Radiating block adopts aluminium alloy extruded one-tenth slab construction, the outside is provided with the heat radiation rib, the led light source support is coated with conduction estersil and directly closely contacts with radiating block, can quickly the heat that led light source produced be distributed, guarantee the required operating ambient temperature of led light source operate as normal, thereby prolonged the service life of LED light fixture.Diffuser, Lamp cup are formed reflective optical system, and the light that led light source produces is redistributed, and Lamp cup adopts the minute surface aluminium sheet of high reflectance, can strengthen the reflection of light, improve the light efficiency of entire module;
