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 Grille lamp that generally uses adopts T8, T5 straight tube fluorescent lamp as light source more at present.The general lamp tube service life of this straight tube fluorescent lamp is short, and photochromic soft inadequately, and flicker is arranged, and trunon delay time is long.Must be equipped with ballast simultaneously obviously improves power consumption.Use mercury, can the serious harm 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.
The LED straight tube light source of existing market has solved the some shortcomings of the traditional T8 of existing use, the existence of T5 straight tube fluorescent lamp, but owing to adopt low power LED as light source, its luminous flux is obviously not enough, LED is enclosed in the glass tube, weak heat-dissipating, inconvenient maintenance, and owing to adopt many series circuits, fault rate is high, and shortened its service life on the contrary.
The utility model content
The purpose of this utility model is improved at existing low-power LED straight tube light source and T8, T5 straight tube fluorescent lamp above shortcomings exactly, and a kind of illumination, good heat dissipation effect are provided, and interchangeability is strong, structure uniqueness, led light source module easy to maintenance.
The purpose of this utility model is achieved in that the led light source module, comprise diffuser 1, lamp body 2, end cap 3, side reflector 4, top reflector 5, led light source 6, pcb board 7, sealing strip 8, it is characterized in that described pcb board 7 is connected lamp body 2 inside top, led light source 6 is welded on the lamp body 2 inside top pcb boards 7 by scolding tin, lamp body 2 is provided with concave inward structure, be provided with the heat radiation rib in the outside of recess, top reflector 5 is installed in lamp body 2 inside top, diffuser 1 is contained in the slot of lamp body 2 bottoms, sealing strip 8 is arranged in the gap between diffuser 1 and the lamp body 2, side reflector 4 is contained in the slot of lamp body 2 sides, and end cap 3 is fastened on lamp body 2 two ends and forms airtight cavity.
Described heat radiation rib is a parallel strip or radial.
The shape of described cavity is trapezoidal or square or semicircle camber or parabolic shape.
Described led light source 6 is a plurality of, forms a row or two rows or three rows.
The material of described diffuser 1 is the transparent glass or the prism PMMA of high transmission rate.
The utility model novel structure, rationally simple, good integrity is manufactured, the processing assembling is convenient.The led light source module can be used as the light source of light fixture such as Grille lamp, by end cap module is fixed on the Grille lamp, does not need dismounting just can directly install when mounted.Also can be made into light belt, combination lamp of various moulding etc., and excellent interchangeability.The lamp body arranged outside strip heat radiation rib, the led light source support is coated with conduction estersil and directly closely contacts with lamp body, 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 prolong the service life of LED light fixture.Side reflector, top reflector adopt the specular material of high reflectance, can strengthen the reflection of light, improve the light efficiency of entire module.
