Description

A kind of LED lamp of reflecting condensation

Technical field

The utility model relates to a kind of LED lamp, relates in particular to a kind of LED lamp of reflecting condensation; Specifically, relate to a kind of LED lamp that improves optical efficiency by the light reflection and the optically focused of reflecting surface.

Background technology

LED (semiconductor light-emitting-diode) be after incandescent lamp and fluorescent lamp the 4th generation semiconductor illuminating light source.Because advantages such as the LED illuminating lamp has the luminous efficiency height, the light quality is good, energy consumption is little, the life-span is long, reliability and durability, applying flexible, safety, environmental protection, response time are short will become another significant qualitative leap on the illumination history.

Existing LED lamp all is a kind of direct projection lamps, and promptly LED light is directly launched, and comprises point, line, surface LED lamp, and the sense that the people is had dazzle the eyes is as Fig. 1,2,3.

As Fig. 4, this LED lamp is a kind ofly to have the encapsulation of transparent or semitransparent plastic cement to form outside linear LED lamp, is used for neon light more:

If when 1. perspex encapsulated, linear LED lamp presented a kind of discrete light beam;

If when 2. translucent plastic cement encapsulated, linear LED pipe presented a kind of light beam of muddiness, optical efficiency is lower.

Summary of the invention

The purpose of this utility model just is to overcome the above-mentioned shortcoming and defect that existing LED lamp exists, and a kind of LED lamp of reflecting condensation is provided.

The purpose of this utility model is achieved in that

The utility model comprises LED, Baltimore groove, bullet and packaging body; The sidewall of Baltimore groove is provided with LED, is provided with bullet in the bottom of Baltimore groove, is provided with packaging body at the top of Baltimore groove.

Its operation principle is: the light part that LED sends is a direct light, and a part is by the indirect light behind the bullet reflecting condensation, has not only eliminated the discreteness of light, and has improved luminous efficiency.

The utlity model has following advantage and good effect:

1, simple in structure, produce easily;

2, luminous mass is good;

3, luminous efficiency height.

In a word, because therefore the utility model ratio of performance to price height has wide application prospect.

The specific embodiment

Describe in detail below in conjunction with drawings and Examples:

One, overall

The utility model comprises LED1, Baltimore groove 1, bullet 3 and packaging body 4; The sidewall of Baltimore groove 2 is provided with LED1, is provided with bullet 3 in the bottom of Baltimore groove 2, is provided with packaging body 4 at the top of Baltimore groove 2.

Two, the setting of bullet 3

1) bullet is set half

As Fig. 5, structure of the present utility model is: a sidewall of Baltimore groove 2 is provided with LED1, is provided with half bullet 3 in the bottom of Baltimore groove 2, is provided with packaging body 14 at the top of Baltimore groove 2.

2) bullet is set

As Fig. 6, structure of the present utility model is: be respectively arranged with LED1 on the sidewall of the left and right sides of Baltimore groove 2, be provided with a bullet 3 in the bottom of Baltimore groove 2, be provided with packaging body 4 at the top of Baltimore groove 2.

3) two bullets are set

As Fig. 6, structure of the present utility model is: be respectively arranged with LED1 on the sidewall of the left and right sides of Baltimore groove 2, be provided with two bullets 3 in the bottom of Baltimore groove 2, be provided with packaging body 4 at the top of Baltimore groove 2.

4) three bullets are set

As Fig. 7, structure of the present utility model is: be respectively arranged with LED1 on the sidewall of the left and right sides of Baltimore groove 2, be provided with three bullets 3 in the bottom of Baltimore groove 2, be provided with packaging body 4 at the top of Baltimore groove 2.

Three, bullet 3

Bullet 3 is the acute angle bullet, and incident light is carried out usable reflection.

The reflecting surface of bullet 3 or be the plane; Or be cambered surface, help optically focused.

Bullet 3 or be the transparent body, or be opaque body, the existing reflection of the transparent body also has refraction action, and opaque body has only reflex.

At present, the white light that is used to the LED lamp that throws light in a large number is to be formed by blue-ray LED+yellow fluorescent powder encapsulation.

The utility model scribbles redness or yellow fluorescent powder at the reflecting surface of bullet 3, forms a kind of exciting light again.Reverberation+exciting light is far longer than direct light.

Four, packaging body 4

Packaging body 4 or be clear glass, or be epoxide-resin glue, LED1 is carried out seal protection, make reflection ray soft.

Five, form series of products

By above-mentioned analysis, being provided with of bullet 3 have half respectively, one, two and three, and number is complex structure at most, but effective, can form series of products as required.

Six, Baltimore groove 2 and bullet 3 are integrated

Baltimore groove 2 and bullet 3 are integrated or injection molded by plastic cement; Or be stamped to form by aluminium.

As Fig. 9, two the utility model oppositely are integrated, make LED luminous up and down, improve luminous efficiency.
