Abstract

The utility model discloses a light emitting diode (LED) daylight lamp preventing light spots. The LED daylight lamp comprises a strip-shaped lamp base which is provided with a strip-shaped lamp cover and a strip-shaped aluminum base plate. The aluminum base plate is provided with an LED lamp bead group. The strip-shaped lamp base is provided with a driving power. The strip-shaped lamp cover is in a semi-oval shape. A short shaft of the semi-oval lamp cover is parallel with an opening of the semi-oval lamp cover. According to the LED daylight lamp, the LED lamp bead group is close to a transverse shaft of the semi-oval lamp cover, the distance between the inner wall of the semi-oval lamp cover and the LED lamp bead group increases, light shining on the semi-oval lamp cover is uniform, further the functions of reducing and even eliminating the light spots are achieved, light shining becomes uniform, and lighting effects are improved.

Description

Prevent the LED fluorescent lamp of hot spot
Technical field
The utility model relates to a kind of illuminating lamp, relates in particular to a kind of LED fluorescent lamp.
Background technology
The LED fluorescent lamp is a kind of energy-conserving and environment-protective illuminating product of novelty, and it can substitute the general lighting lamp and be widely used in the places such as office, school, market, underground garage, have economize on electricity, life-span long, without advantages such as stroboscopic, heavy metal frees.But the fluorescent lamp that uses at present generally adopts the SMD3528 paster LED as luminescent device, and this class device power is little, and poor radiation wants to satisfy certain brightness demand, and a SMD3528 paster LED number of use is many.Simultaneously, owing on a lamp body a plurality of SMD3528 paster LEDs can be set, it is rounded to add most fluorescent tube cross sections, poor to the distributional effects of light, therefore produces easily in use a large amount of hot spots, causes illuminating effect bad.
Summary of the invention
Technical problem to be solved in the utility model provides the effective LED fluorescent lamp that prevents hot spot of a kind of distribution of light.
For solving the problems of the technologies described above, the technical solution of the utility model is: the LED fluorescent lamp that prevents hot spot, comprise the strip lamp socket, on the described strip lamp socket strip lampshade is installed, the strip aluminium base is installed on the described lamp socket, LED lamp pearl group is installed on the described aluminium base, on the described strip lamp socket driving power is installed, described strip lampshade is the half elliptic lampshade, and the minor axis of described half elliptic lampshade is parallel with the opening of described half elliptic lampshade.
As preferred technical scheme, described lampshade is the PC cover body.
As preferred technical scheme, described LED lamp pearl group comprises SMD3014 paster LED lamp pearl.
As preferred technical scheme, described LED lamp pearl group comprises at least two strings LED lamp pearl group parallel with one another, and described LED lamp pearl group comprises at least two mutually LED lamp pearls of series connection.
Owing to adopted technique scheme, prevent the LED fluorescent lamp of hot spot, comprise the strip lamp socket, on the described strip lamp socket strip lampshade is installed, the strip aluminium base is installed on the described lamp socket, LED lamp pearl group is installed on the described aluminium base, on the described strip lamp socket driving power is installed, described strip lampshade is the half elliptic lampshade, and the minor axis of described half elliptic lampshade is parallel with the opening of described half elliptic lampshade; The half elliptic lampshade of use of the present utility model, make LED lamp pearl group near the transverse axis place of half elliptic lampshade, distance between half elliptic lampshade inwall and the LED lamp pearl group is increased, the light that is radiated on the half elliptic lampshade is more even, and then play the effect that reduces even eliminate hot spot, make the light irradiation become more even, improve lighting effect.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is that the A-A of Fig. 1 is to view;
Fig. 3 is the electrical schematic diagram of the utility model embodiment;
Among the figure: the 1-lampshade; The 2-aluminium base; The 3-driving power; 4-paster LED lamp pearl; 5-LED lamp pearl group; 6-strip lamp socket.
The specific embodiment
Below in conjunction with drawings and Examples, further set forth the utility model.In the following detailed description, only by the mode of explanation some example embodiment of the present utility model has been described.Undoubtedly, those of ordinary skill in the art can recognize, in the situation that does not depart from spirit and scope of the present utility model, can revise described embodiment with various mode.Therefore, accompanying drawing is illustrative with being described in essence, rather than is used for the protection domain of restriction claim.
As depicted in figs. 1 and 2, prevent the LED fluorescent lamp of hot spot, comprise strip lamp socket 6, on the described strip lamp socket 6 strip lampshade 1 is installed, described lampshade 1 can spiral-lock on lamp socket, easy accessibility is convenient to safeguard.Strip aluminium base 2 is installed on the described lamp socket, and described aluminium base 2 can be fixed on by the mode of setting-in on the described strip lamp socket 6, and described aluminium base 2 is easy heat radiation as the benefit of LED lamp pearl installing plate, helps to improve the service life of fluorescent lamp; Certainly, also can select according to actual needs the LED lamp pearl installing plate of other quality, these select not to be subjected to the restriction of present embodiment.LED lamp pearl group is installed on the described aluminium base 2, on the described strip lamp socket 6 driving power 3 is installed, described driving power 3 connects aluminium base 2 by wire, and being embodied as LED lamp pearl group provides operating voltage.Described LED lamp pearl group comprises some paster LED lamp pearls 4, the quantity of paster LED lamp pearl 4 can be selected voluntarily according to the size of fluorescent lamp power, the lamp of paster LED described in present embodiment pearl 4 is SMD3014 paster LED lamp pearl, single SMD3014 paster LED lamp pearl power is little, and luminous flux is large, be generally 9-11LM, light decay is low.Under the same brightness demand, compare the paster quantity that needs with the paster LED of other model few.
Described strip lampshade 1 is the half elliptic lampshade, and the minor axis of described half elliptic lampshade is parallel with the opening of described half elliptic lampshade.The lampshade 1 of semi-ellipsoidal cross section, make LED lamp pearl group near the focus of oval lampshade 1, distance between lampshade 1 inwall and the LED lamp pearl group is increased, the light that is radiated on the half elliptic lampshade is more even, solved the hot spot problem of LED fluorescent lamp, in the present embodiment, described lampshade 1 is set to milky PC cover body, easily moulding is used more comfortable.
As shown in Figure 3, described LED lamp pearl group comprises at least two strings LED lamp pearl group 5 parallel with one another, and described LED lamp pearl group 5 comprises at least two mutually LED lamp pearls of series connection.Single power of SMD3014 paster LED lamp pearl of present embodiment is 0.1W, take the LED fluorescent lamp of 12W as example, can adopt 120 SMD3014 paster LED lamp pearls, per ten SMD3014 paster LED lamp pearls are connected into LED lamp pearl group 5,120 SMD3014 paster LED lamp pearls form 12 groups of LED lamp pearl groups 5, then 12 string LED lamp pearl groups 5 are connected in parallel, fabrication and installation are very simple, after wherein a string LED lamp pearl group 5 quits work, can section do not affect the work of other LED lamp pearl group 5, improved the reliability that whole fluorescent lamp uses.
