Abstract

Disclosed is a special intensifying strip for fluorescent tube employing low-power LED as illuminant, which is formed in one step through casting method; the middle segment of the intensifying strip is horizontal viewing from both ends, and tilting segments in the same angle are formed on both ends; a LED lamp tube is mounted on each tilting segment for increasing the illumination angle of the LED fluorescent lamp; the intensifying strip has three rows of round holes looking down from upper side so that the LEDs can be embedded in the round holes; a circular paraboloid is formed under each round hole looking up lower side; thereby, the scattered light from the embedded LEDs is condensed to intensify the direct radiation intensity of LED fluorescent lamp; less LEDs are used to obtain better lighting effect through the optical processing; when the LED fluorescent lamp is additionally mounted with the special intensifying strip, the comprehensive cost is reduced and the electricity saving effect is improved.

Description

A kind of being used for the low-power LED is the special-purpose enhancing strip of fluorescent tube of illuminator

Affiliated technical field

The utility model relate to a kind of through optical design go out to be used for the low-power LED be the accessory of the fluorescent tube of illuminator, especially can increase the irradiating angle of this type of fluorescent tube, can strengthen the direct projection intensity of this type of fluorescent tube again, thereby accomplish reaching under the preceding topic of equal whole lighting effect, can reduce the usage quantity of low-power LED by a relatively large margin, reduce the production cost of this type of fluorescent tube, a kind of being used for the low-power LED that increases its energy-saving effect is the special-purpose enhancing strip of fluorescent tube of illuminator.

Background technology

At present, known be in the fluorescent tube of illuminator with the low-power LED, plurality of rows LED is welded in the same printed board abreast, the direct projection direction that causes all low-power LEDs is all perpendicular to ground, in order to improve the too small defective of bringing therefrom of irradiated area, the general big straw hat type LED of irradiating angle that all adopts, but the weak point of bringing simultaneously is that direct light intensity is low, in order to improve direct projection intensity, the way that adopts is the usage quantity that increases low-power LED, increase luminous density, so production cost increases also.Again owing to increase the usage quantity of low-power LED, increase power consumption simultaneously, reduced energy-saving effect.

Summary of the invention

In order to overcome existing is deficiency more than the fluorescent tube of illuminator with the low-power LED, it is the special-purpose enhancing strip of fluorescent tube of illuminator that the utility model provides a kind of being used for the low-power LED, trial designs by secondary optics, create a kind of new parts, with after it, can increase the irradiating angle of this type of fluorescent tube, can strengthen the direct projection intensity of this type of fluorescent tube again, thereby accomplish under the preceding topic of equal whole lighting effect, can reduce the usage quantity of low-power LED by a relatively large margin, reduction is the production cost of the fluorescent tube of illuminator with the low-power LED, increases its energy-saving effect.

The technical scheme that its technical problem that solves the utility model adopts is: the enhancing strip of casting, it has three angled, and each face top-pour is cast with row's circular hole, is used for supporting LED lamp bar, each LED can be penetrated in the hole, and it is circular one by one parabolic to have cast at the another side in hole.

Three angled faces make three LED lamp bars shine to different angles, increase irradiating angle; The circular parabolic scattered light optically focused that each straw hat type LED is sent strengthens direct projection intensity, like this, just need not rely on the use amount that increases LED simply and improve illuminating effect, has both reduced cost, has and has improved power savings.In addition, circular paraboloidal reflection ray is between two adjacent LED, and that gives the people feels it is the luminous point increase of LED, has worked to change the small light spot sense.

The beneficial effects of the utility model are, with parts simple in structure, with the idea of optical design, improve with the low-power LED is the illuminating effect of the fluorescent tube of illuminator, reach the price of further reduction LED fluorescent lamp, improve power savings, accelerate popularizing of LED ligthing paraphernalia.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is two views of the present utility model.Fig. 2 is that the utility model cooperates figure with the fluorescent lamp body.

Fig. 3 is an increase irradiating angle schematic diagram of the present utility model.Fig. 4 is an enhancing direct projection intensity schematic diagram of the present utility model.

1. enhancing strip bodies among the figure, 2. circular hole is 3. circular parabolic, 4.LED, 5. transparent outer tube.

The specific embodiment

Processing enhancing strip body (1) earlier as Fig. 1, get out circular hole (2) then on enhancing strip body (1), is that the center car goes out circular parabola with circular hole (2), just the utility model is finished again.

During use, to be welded on LED (4) on the bar shaped printed circuit board (PCB) earlier by the spacing that enhancing strip body (1) is gone up circular hole (2) in enhancing strip body (1) back side embeds circular hole (2), by Fig. 2 the enhancing strip body (1) that is embedded with LED (4) be inserted in the circular transparent pipe of fluorescent lamp then.

Fig. 3 top has shown the group photo firing angle of three LED when not using the utility model, and the below has shown the increase of using the group photo firing angle of three LED behind the utility model.

Fig. 4 top has shown the direct projection ability of three LED when not using the utility model, and the below has shown the enhancing of using the direct projection ability of three LED behind the utility model.

Through with this embodiment cross-reference, the increase of irradiating angle can reach 20 degree at least, and the enhancing of direct projection illumination can reach about 50%, and the hot spot sense alleviates.

Claims

One kind to be used for the low-power LED be the special-purpose enhancing strip of fluorescent tube of illuminator, be to be placed in the fluorescent lamp body, upload the printed board that is welded with low-power LED, and the light that each low-power LED sends played focusing, strengthens parts of its direct projection intensity, it is characterized in that: be one and be processed into the certain thickness casting matrix of having of loose structure.
