Abstract

The utility model relates to a lamp used for illumination, in particular to an LED illuminating lamp. The LED illuminating lamp comprises a plurality of LEDs, a lamp panel and a power circuit, wherein the lamp panel is composed of a frame body, and a bottom plate nested in the frame body, and a flat plate type light conducting compound body is nested on the bottom plate and in the frame body, a plurality of line shaped LED light sources are positioned on the lateral surface of the light conducting compound body, and the light emitted by the LEDs emits light outward after passing through the light conducting compound body. Because a plurality of LEDs are positioned on the lateral surface of the light conducting compound body, the LED illuminating lamp adopts a side-emitting method, the light emitted by the LEDs emits light outward after passing through the light conducting compound body, therefore, the technical effect of even and mellow illumination is achieved, and the disadvantage of uneven illumination intensity resulting from the individual difference of the LED is avoided.

Description

A kind of LED illuminating lamp

Technical field:

The utility model relates to a kind of lighting lamp, refers in particular to a kind of LED illuminating lamp that LED is applied to lighting use.

Background technology:

LED is used in recent years in a large number as light source, because its compare with the conventional lights source possess energy-saving and environmental protection, advantage that the life-span is long, but also it directly not being used as illumination at present uses etc., reason has: with present LED manufacturing process, the LED luminous efficiency individual difference of producing is bigger, with superseded, qualification rate is on the low side, causes manufacturing cost higher through a large amount of selections; The single manufacturing cost of LED is also higher again, and single LED luminance is lower, and will satisfy lighting demand, by present " end is luminous " mode, be about to the bottom surface that LED is arranged in the chassis one by one, then to dispose a considerable amount of LED, if LED is selected one by one, if cost height then is not selected, then there is illuminance difference again, influences result of use, and, LED is owing to adopt the lining mode, for optically focused, prism is set on the chassis usually, cause the shortcoming that gray scale is big and lighting angle is less.So existing LED can't be widely used in the normal lighting field.

Summary of the invention:

The purpose of this utility model is to provide the relatively low LED illuminating lamp of a kind of manufacturing cost to improve structure, but can better satisfy lighting demand.

The technical solution of the utility model is such:

A kind of LED illuminating lamp, comprise some LED, lamp panel and power circuit, the base plate that described lamp panel is inlayed wherein by a framework and constitutes, also inlay a tabular leaded light complex on the described base plate, in the framework, some LED are positioned at leaded light complex side, and linear LED emitted light is outwards luminous again behind the leaded light complex.

Further, described leaded light complex is arranged one by one by following structure:

A. reflexed light film, its one side contacts cooperation with described base plate;

B. the site layer is evenly distributed with fine mesh on it, and the mesh bore is relatively large in centre, less relatively all around;

C. lower floor's leaded light flaggy, lay a plurality of linear LED lamp sources and a plurality of strip retroreflective sheeting or shading diaphragm around its side respectively, described linear LED lamp source is evenly put and is fixed in this strip circuit board and forms by some LED, and towards the inboard, and these a plurality of strip circuit boards are corresponding and are provided with, and a plurality of strip retroreflective sheeting or shading diaphragm also are corresponding setting;

D. first spreads rete;

E. second spreads rete;

F. upper strata leaded light flaggy.

Further, described site layer can adopt the silk-screen mode directly to be printed in above lower floor's leaded light flaggy.

Further, be coated with retroreflective sheeting or shading diaphragm around the leaded light flaggy of described upper strata.

Further, described fine mesh can be circle, can also be rhombus.

Further, described linear LED lamp source can be straight, also can be around song.

The utility model is owing to adopt the leaded light complex, some again linear LED lamps source is positioned at leaded light complex side and promptly adopts the side illumination mode, some linear LED lamps source emitted light is outwards luminous again behind the leaded light complex, realize the technique effect that illumination is even, soft, avoided the shortcoming of the uneven illumination that brings because of LED lamp source individual difference.

The specific embodiment:

Now in conjunction with the accompanying drawings the utility model structure is elaborated:

Shown in Fig. 1-8, a kind of LED illuminating lamp, comprise two linear LED lamp sources (1), lamp panel (2) and power circuit, power circuit is arranged in the power pack (5) at lamp panel (2) back side, the base plate (22) that lamp panel (2) is inlayed wherein by a framework (21) and constitutes, base plate (22) is gone up, also inlay a tabular, tetragonal leaded light complex (3) (the utility model profile can also be other moulding beyond the square) in the framework framework (21), and leaded light complex (3) is arranged one by one by following structure:

A. reflexed light film (31), its one side contact cooperation with described base plate (22), plays the effect of increase illumination;

B. site layer (32) is evenly distributed with fine mesh on it, and the mesh caliber size is 0.50～0.81mm, mesh spacing 0.75～0.90mm, and the mesh bore was relatively more little around the mesh bore was relatively large in centre, past more, and this fine mesh can be circle, can also be rhombus.

Shown in Fig. 3,4, site layer (32) can adopt the silk-screen mode directly to be printed in lower floor's leaded light flaggy (33) upper surface.

C. lower floor's leaded light flaggy (33), adopt PMMA acrylic block material, lay two linear LED lamp sources and two strip retroreflective sheetings or shading diaphragm around its side respectively, evenly put on each strip circuit board and be fixed with dozens of LED (LED quantity with lower floor leaded light flaggy size relevant) and form linear LED lamp source, this strip board substrate can be for moulding or soft moulding firmly, be that linear LED lamp source can be straight, also can be around song, be suitable for using when being discoid when leaded light complex of the present utility model (3) profile, and it is consistent towards the inboard, and these two strip circuit boards are corresponding the setting promptly and are provided with face-to-face, and these two strip retroreflective sheetings or shading diaphragm also are the corresponding setting face-to-face that is provided with promptly, be that linear LED lamp source is positioned at leaded light complex side, and linear LED lamp source emitted light is outwards luminous again behind the leaded light complex;

D. the first diffusion rete (34), E. second spread rete (35); Play effect, make out the soft effect of light light diffuse reflection, scattering;

F. upper strata leaded light flaggy (36) also adopts PMMA acrylic block material, plays the effect of protection diffusion rete, and upper strata leaded light flaggy (36) is coated with retroreflective sheeting or shading diaphragm (37) all around, can prevent that light from directly spilling from side.
