At present, existing part light fixture adopts LED as light source, but this LED lamp distribution is undesirable, as have that luminous angle is too little, light intensity is not enough, luminous problem such as even inadequately.

Summary of the invention

The purpose of the embodiment of the invention is to provide a kind of LED light fixture, is intended to solve the existing undesirable problem of LED lamp distribution.

The embodiment of the invention is to realize like this; A kind of LED light fixture; Comprise a lamp tube, establish the fixed head that a cross section is V-shape in the said lamp tube, said fixed head has surface and opposed surface in opposite directions; The surface in opposite directions of said fixed head is provided with many radiating ribs, and the opposed surface of said fixed head is evenly equipped with a plurality of LED.

The embodiment of the invention is distributed in fixed head two opposed surface that cross section is " V " font with a plurality of LED; The light mutual superposition that each LED sends; Bright dipping is even, and luminous angle and light intensity are enough big, and distribution curve flux approaches the distribution curve flux of florescent lamp fitting; Satisfy the light distribution requirements of LED light fixture, and anti-seismic performance and shock resistance are good.

The specific embodiment

In order to make the object of the invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.

The embodiment of the invention is distributed in fixed head two opposed surface that cross section is " V " font with a plurality of LED; The light mutual superposition that each LED sends, bright dipping is even, and luminous angle and light intensity are enough big; Distribution curve flux approaches the distribution curve flux of florescent lamp fitting, satisfies the light distribution requirements of LED light fixture.

The LED light fixture that the embodiment of the invention provides comprises a lamp tube; Establish the fixed head that a cross section is V-shape in the said lamp tube; Said fixed head has surface and opposed surface in opposite directions, and the surface in opposite directions of said fixed head is provided with many radiating ribs, and the opposed surface of said fixed head is evenly equipped with a plurality of LED.

Below in conjunction with specific embodiment realization of the present invention is described in detail.

Shown in Fig. 3～7; The LED light fixture that the embodiment of the invention provides comprises a lamp tube 1; Establish the fixed head 2 that a cross section is " V " font in this lamp tube 1, this fixed head 2 has surface 21 and opposed surface 22 in opposite directions, and a plurality of LED3 are distributed in the opposed surface 22 of fixed head; The surface 21 in opposite directions of fixed head 2 is provided with many radiating ribs 5, and the opposed surface 22 of fixed head 2 is evenly equipped with a plurality of LED3.The light mutual superposition that each LED3 sends is also even through the 1 transmission bright dipping of lamp tube; Luminous angle and light intensity are enough big, and distribution curve flux approaches the distribution curve flux of florescent lamp fitting, satisfy the light distribution requirements of LED light fixture fully; And radiating ribs 5 enlarges area of dissipation, has improved the reliability of this LED light fixture.

2 liang of opposed surface of said fixing plate, 22 angle θ are preferably 122～125 °, and correspondingly, the optical axis angle that is positioned at fixed head two opposed surface LED is 55～58 °.This fixed head 2 is suitable for the installation of big luminous corner LED.

The embodiment of the invention adopt power be the above white light LEDs of 1W as light source, its luminous angle is 110～130 °, is similar to lambert's body radiant light.The light that this big lighting angle LED sends will be in the below of fixed head mutual superposition, reach the effect of even optical illumination.

Above-mentioned LED3 can be fixedly arranged on the opposed surface 22 of fixed head 2 by aluminium base 4, and between each opposed surface adjacent LED is 15～25mm apart from d.Certainly, for strengthening heat conduction, 2 of 4 of LED3 and aluminium bases and aluminium base 4 and fixed heads are coated with heat conductive silica gel.In addition, 2 liang of opposed surface of fixed head are beneficial to assembling by fillet 6 smooth connections.

The embodiment of the invention is tested a plurality of samples, and distribution curve flux is as shown in Figure 8.Fixed head 2 each opposed surface are provided with 5 LEDs, and the distance between each opposed surface adjacent LED is 20mm.2 liang of opposed surface angles of fixed head are 123 °, and the optical axis angle of fixed head two opposed surface LED is 57 °.Wherein the size a of LED3 is 3.45mm, and power is 1W, and luminous angle is 115 °.
