Abstract

The invention discloses a thin high power LED (Light Emitting Diode) line lamp. The thin high power LED line lamp also comprises a long strip light guiding plate (6) apart from the parts of the traditional line lamp; LED light sources (3) are formed by lengthwise arranging a plurality of LED lamp beads in one to three rows; the heat sink comprises a heat dissipation baseplate (4) and cooling fins (7); the heat dissipation baseplate (4) takes the shape of a long strip; the cooling fins (7) are arranged at intervals in parallel along the direction vertical to the heat dissipation baseplate; a light emitting module (8) is formed by the LED light sources (3) and the heat sink; the light emitting module (8) and the long strip light guiding plate (6) are horizontally arranged; the horizontally arranged light emitting module (8) is glued to the side arris of the light guiding plate (6); and the LED light sources (3) face toward the interior of a light guiding plate body. The thin high power LED line lamp has the advantages that the characteristics of the LED light sources and indoor illumination are fully considered; as the light sources are horizontally arranged, the light emitting effect is effectively improved, and the heat dissipation effect is good; and the body of the thin high power LED line lamp is light and thin.

Description

Slim great power LED line lamp

Technical field

The present invention relates to the semiconductor lamp field, particularly a kind of radiating fin is distributed in the slim great power LED line lamp of lamp body side.

Background technology

Semiconductor lighting has plurality of advantages such as high brightness, low energy consumption, life-span length, environmental protection; The every field that is applied to throwing light on just more and more widely; But since the principle of luminosity of light emitting diode with go out light characteristic and conventional light source has very big difference; Especially requiring aspect the more harsh room lighting more, stricter requirements that its Design of Luminaires has.Line lamp is a kind of high-end decoration and illuminating product, and is very popular, but in common line lamp, uses led light source; Owing to adopt common rhombus lampshade, serious hot spot is arranged and produce dazzle, so; Existing LED line lamp forms soft, uniform exiting surface through the mode of on lamp housing, setting up the luminous intensity distribution lampshade, and Chinese patent document CN201764281U discloses a kind of LED line lamp, and led light source is installed in the lamp housing; Vertical bar line lampshade is fixed on the lamp housing, and led light source is placed in the vertical bar line lampshade, it is characterized in that; One transparent vertical bar card is housed between led light source and the vertical bar line lampshade; Vertical bar line on the vertical bar line lampshade and transparent vertical bar card get the vertical bar line shape that is orthogonal, and the led light source bright dipping of this scheme is carried out secondary reflection, refraction respectively on transparent vertical bar card and vertical bar line lampshade, further evenly bright dipping; But this scheme still adopts the usual basic structure that is followed successively by radiator, light source, lampshade; Be difficult to adapt to the requirement of high-power line lamp, when increasing owing to single lamp pearl luminous intensity on the one hand, it is more obvious that hot spot and glare effect can become; On the other hand,, not only be difficult to satisfy the thermal diffusivity requirement of high-power LED lamp, and cause the thickness of light fixture to be difficult to reduce because radiator is positioned at the light fixture back side.

Summary of the invention

The objective of the invention is to overcome the prior art shortcoming; A kind of slim great power LED line lamp that is suitable for indoor use is provided; Not only have the higher heat dispersion of existing lines light fixture, better go out light effect, and body is frivolous, especially is suitable as indoor ceiling light and uses.

The objective of the invention is to adopt following technical scheme to realize: slim great power LED line lamp, include lamp housing, lampshade, led light source, radiator and driving power circuit, through lamp housing each parts is assembled and be integral; Said slim great power LED line lamp also includes the LGP of strip; Said led light source divides one to three row's file to arrange by some LED lamp pearls and forms the lamp bar, and said radiator is made up of heat-radiating substrate and radiating fin, and heat-radiating substrate is a strip; Radiating fin is arranged along the direction spaced and parallel perpendicular to heat-radiating substrate; Led light source fits tightly on heat-radiating substrate, constitutes light emitting module jointly with radiator, and light emitting module and LGP average level are installed; The light emitting module of horizontal is fitted in the side rib of LGP, and led light source is in the leaded light plate body.

Further technical scheme is: the quantity of said light emitting module is two groups, the light emitting module of two horizontal with a LGP clamping in the centre.

Scheme further is: said led light source adopts two in line LED lamp pearl dislocation to arrange and forms, and the distance between the adjacent two LED lamp pearls equates arbitrarily.

Scheme further can also be: said lampshade adopts ground glass to process, and covers fully in LGP one side.

Adopt the slim great power LED line lamp of this structure, take into full account the characteristics of led light source and room lighting, the light source horizontal; Through the bright dipping of LGP refraction back, at first, not only effectively improved and light effect; Make light source even adopt the high-power lamp pearl; Through the LGP homogenize, through the lampshade adjustment, also can obtain the desirable light effect that goes out again; And the present invention is arranged on the exiting surface side with the radiator of line lamp, not only can not influence bright dipping, even and use at indoor top surface, can not cause the heat alluvial yet; Moreover, adopting the LED line lamp of this structure, radiator can be expanded through the plane have bigger heat exchange area, makes whole line lamp have more frivolous body, especially is suitable as indoor ceiling light and uses.

Below in conjunction with accompanying drawing and embodiment the present invention is further set forth, protection scope of the present invention includes but are not limited to accompanying drawing and the disclosed content of embodiment.
