Description

Wide firing angle luminous diode lamp fluorescent lamp radiator

Technical field

The utility model relates to a kind of radiator, particularly relates to a kind of radiator that is used for wide firing angle luminous diode lamp fluorescent lamp.

Background technology

At present, common LED fluorescent lamp, all light source (LED) is fixed on the planar heat spreader, owing to be subjected to the LED process limitation, the lamp luminescence angle is all less than 120 °, therefore cause the lampshade sidewall to form the dark space easily, can't realize＞120 ° do the angle of departure, need the illumination occasion of big lighting angle to use at some.

Summary of the invention

Main purpose of the present utility model is to cause the lampshade sidewall to form the dark space easily at the planar heat spreader that existing LED fluorescent lamp is adopted, can't realize＞120 ° do problem such as the angle of departure, a kind of wide firing angle luminous diode lamp fluorescent lamp radiator is provided.

The utility model is provided with the heat radiation body, and the cross section of described heat radiation body is billiard table shape, is provided with 2 inclination angle faces or 3 inclination angle faces of being used to install led light source on the flat tube body portion, and the angle of adjacent inclination angle face is θ, 180 °＞θ＞120 °.

Described 2 inclination angle faces are left-leaning edged surface and Right deviation edged surface, and the angle of left-leaning edged surface and Right deviation edged surface is θ, 180 °＞θ＞120 °; Described 3 inclination angle faces are left-leaning edged surface, middle inclination angle face and Right deviation edged surface, and the angle of left-leaning edged surface and middle inclination angle face is θ, and the angle of Right deviation edged surface and middle inclination angle face is θ, 180 °＞θ＞120 °.

Because the utility model is provided with the heat radiation body, the cross section of described heat radiation body is billiard table shape, on the flat tube body portion, be provided with 2 inclination angle faces or 3 inclination angle faces of being used to install led light source, the angle of adjacent inclination angle face is θ, 180 °＞θ＞120 °, therefore the utility model provides the LED fluorescent lamp at ° luminous angle, a kind of＞120, adopt the composite light source inclination angle to arrange and solve light firing angle and luminous intensity distribution homogeneity question, solved the problem that existing LED fluorescent lamp needing at some to be unsuitable for the illumination applications of big lighting angle.
