Abstract

The utility model relates to a tubular casing of an LED fluorescent lamp, which comprises a hollow radiating pipe main body with semi-circular cross section, wherein the semi-circular outer surface ofthe main body is provided with waved or grooved stripes and LED fixing clamp grooves are arranged on two sides of a substrate on the lower surface of the main body. Compared with a common LED fluorescent lamp tubular casing, the tubular casing has the advantages that stripes on the outer surface of the overall tubular main body are fine in air ventilation, thermal transmission capacity of the radiating pipe main body is effectively increased by thickening the substrate on the bottom, circle center of the inner semicircle of the hollow semi-circular cross section of the radiating pipe main body is higher than that of the outer semicircle thereof, wherein the thickness of the substrate on the lower surface of the main body ranges from 1mm to 1.5mm, the depth of the stripes is equal to or less than 0.5mm, and the optimum depth of the stripes is 0.3mm. Due to the height difference of circle centers of hollow semicircular inner and outer arcs of the radiating pipe main body, the radiatingpipe meets requirements of heat transfer mechanism, and inside space of the radiating pipe is increased while saving materials. Therefore, the tubular casing which is elegant and attractive in appearance and has better heat transfer and radiating performance compared with the existing products is worthy of being popularized.

Description

LED fluorescent lamp tubulose shell

[technical field]

The utility model relates to a kind of LED fluorescent lamp tubulose shell, refers in particular to a kind of LED fluorescent lamp tubulose shell that has better radiating effect concurrently.

[background technology]

With regard to present technical merit, the LED lighting engineering is compared with the traditional lighting technology, has luminous efficiency height, advantage such as long and environmental protection of energy-conservation, life-span significantly, has established its optimal selection as next generation's illumination.For the needs of illumination, great power LED or array-type LED illuminating lamp product are come out one after another, and the heat that sends during work just becomes and can not look down upon, because higher temperature can make the LED life-span shorten and change glow color.For this reason, all kinds of high-powered LED lamp products all need be provided with corresponding heat abstractor.The LED fluorescent lamp is the class in the LED lighting, and its common structure is as follows: led array is installed on the substrate of aluminium alloy tubulose housing bottom; Tubular shell hollow, power supply are installed in the end in the tubular shell, and the heat that LED lamp and power supply send passes on the tubular shell, is dispelled the heat by tubular shell.The design of most of fluorescent lamp tubulose housings is unreasonable, and is less than normal or the curved wall striped is dark excessively as substrate thickness.Bottom substrate thickness is little, is unfavorable for conducting heat; The curved wall striped is crossed the relevant position wall thickness is reduced, and the heat that passes to the top is few, and the heat that transmit toward the tubular shell direction at the top is few, and is unfavorable for circulation of air.These designs are bad, and to cause installing the position temperature of power supply more much higher than the other end, shorter than the life-span from power supply LED far away near the LED of power supply.Thereby shorten the service life of whole LED fluorescent lamp.

[summary of the invention]

The purpose of this utility model is to have overcome above-mentioned defective, provides a kind of rational in infrastructure, and thermal conductance, heat dispersion are more and LED fluorescent lamp tubulose shell elegant in appearance.

The purpose of this utility model is achieved in that a kind of LED fluorescent lamp tubulose shell, its improvements are: it comprises that hollow section becomes semicircular radiating tube main body, the semicircle outer surface of main body is provided with wave and groove shape striped, is provided with the LED fixed card slot in the both sides of main body lower surface substrate;

The center of circle, interior semicircle place of the hollow semi-circular cross-section of described heat pipe body is higher than the center of circle, outer semicircle place;

Described main body lower surface substrate thickness 1-1.5mm;

Described fringe depths is not more than 0.5mm;

Described fringe depths 0.3mm.

Than common LED fluorescent lamp tubulose shell, the beneficial effects of the utility model are attractive in appearance and circulation of air is better at whole tubular body outer surface striped; Bottom substrate is thickeied, and has effectively improved the main body thermal heat transfer capability; The difference in height in the circular arc and the center of circle, external arc place in main body hollow is semicircular, make that radiating tube meets heat-transfer mechanism, economical with materials again when increasing the inner space, therefore the utility model product has elegant in appearance, and compare now that product has better heat transfer and heat dispersion, be worthy to be popularized very much.

[specific embodiment]

Below in conjunction with accompanying drawing the utility model specific embodiment is described in detail.

As shown in Figure 1, 2, the utility model relates to a kind of LED fluorescent lamp tubulose shell, it comprises that hollow section becomes semicircular radiating tube main body 1, the center of circle, interior semicircle 101 place of the hollow semi-circular cross-section of main body 1 is higher than the center of circle, outer semicircle 102 place, be that the inner surface 101 circular arc centers of circle are higher slightly than the outer surface 102 circular arc centers of circle, thereby make that entire heat dissipation tube body 1 is by thick attenuation from bottom to top, meet heat-transfer mechanism, not only conducted heat well but also economical with materials, also effectively increased the body interior accommodation space.Be provided with wave 110 and groove 111 shape stripeds in main body 1 semicircle outer surface 102, for taking into account the attractive in appearance of outer surface 102 stripeds and being beneficial to circulation of air, those waves 110 and groove 111 fringe depths are not more than 0.5mm usually, the best is got 0.3mm, so that influence wall thickness less as far as possible, be beneficial to and heat is passed to the top and conduct heat to the tubular shell other end; The waveform striped is less relatively to the circulation of air influence.Main body 1 lower surface substrate 103 is then thickeied to 1-1.5mm, and the best is got 1.3mm, has effectively improved its vertical heat-transfer capability, is beneficial to the tubular shell direction and conducts heat.Substrate 103 both sides are provided with LED fixed card slot 104.

Thus one, the utility model LED fluorescent lamp tubulose shell in use, the LED lamp plate is installed on the substrate 103 of tubulose radiating tube main body 1 bottom, main body 1 hollow, power supply is installed an end within it, and the heat that LED lamp and power supply send passes on the tubular shell, by 1 heat radiation of radiating tube main body.The position of power supply is installed because the heat that the heat that existing power supply produces also has LED to produce makes this place's heat more than other places.The substrate 103 of radiating tube main body 1 thickening and thicker arcwall make heat better be delivered to low-temperature space, reach the effect that reduces power supply unit megadyne temperature degree.Because the heat energy at power supply position is delivered to low-temperature space preferably, the low-temperature space temperature rises, and the temperature difference increases, and is more with the heat exchange amount of air, adds that the outer surface striped is less relatively to the circulation of air influence, and circulation of air is more smooth and easy on the outer surface.Thereby make light fixture integral body obtain good heat transfer and radiating effect

In sum, the utility model is through to the improvement of radiating tube, the power supply of its upper installation when it is used Easier being delivered on the whole housing of heat, avoided localized hyperthermia, improved the service life of light fixture. Just because of it conducts heat, whole light fixture temperature difference less, outer surface is beneficial to again circulation of air, thereby whole Individual light fixture obtains good radiating effect.
