Fig. 4 is a profile, and one second preferred embodiment of the utility model LED lighting device is described.

The specific embodiment

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

Consult Fig. 2,3, first preferred embodiment of the utility model LED lighting device 2, wherein Fig. 2 is the side view of this first preferred embodiment, Fig. 3 then is the profile of this first preferred embodiment.This LED lighting device 2 comprises a lamp socket 21, and is arranged at luminescence unit 22 on this lamp socket 21, and one is arranged on this lamp socket 21 and covers the lampshade 23 of this luminescence unit 22.

This lamp socket 21 comprises a joint portion 211, and this luminescence unit 22 comprises that one is arranged at the LED element 222 on this lamp socket 21.Certainly, during actual the use, the quantity of this LED element 222 also can be more than two, or is replaced as the light source of other kind, the neither effect that influences this LED lighting device 2.

23 on this lampshade is arranged on this lamp socket 21, comprises a junction 231, a refraction part 232 that the direction toward these lamp sockets 21 is extended from this connecting portion 231, and one connects this refraction part 232 and to the depressed part 233 of the direction depression of this connecting portion 231.This connecting portion 231, this refraction part 232 and this depressed part 233 are around defining a confined space 234.Wherein, this lampshade 23 is to be attached on this joint portion 211 by this refraction part 232, and this refraction part 232 has identical refractive index with this connecting portion 231.In addition, this refraction part 232, this

depressed part

233 and 21 common cooperations of this lamp socket define an accommodation space 24, this LED element 222 be arranged in this accommodation space 24 and be positioned at this lampshade 23 depressed part 233 under.

During use and since this LED element 222 be positioned at this depressed part 233 under and near this depressed part 233, so the light that gives out of this LED element 222 can penetrate this depressed part 233 and this refraction part 232 and enters in this confined space 234.At this moment, by the design of this refraction part 232 and this depressed part 233 relative positions, can make the light of this LED element 222 when penetrating this refraction part 232, change direct of travel, and then converge the light predetermined direction that leads concentrated.Further, the radian of this connecting portion 231 also can be before light passes this confined space 234 be done the direct of travel of light adjustment again, strengthens the effect that light is concentrated.

What need special instruction is that in this preferred embodiment, for reaching the effect that changes light going direction, the thickness of this refraction part 232 is the thickness greater than this connecting portion 231, and the thickness of this refraction part 232 is cumulative to the centre by two ends.By the cumulative design on thickness of this refraction part 232, the light direct of travel through this refraction part 232 time that makes this LED element 222 disperse changes, and then light is concentrated the guiding predetermined direction, but the aspect during practical application is not as limit.The utility model LED lighting device 2 can be concentrated the direction of light according to desire, adjusts the thickness of this refraction part 232, and light is concentrated toward predetermined direction.

In addition, not only change the direct of travel that these refraction part 232 thickness can change light, the refractive index of adjusting this refraction part 232 also can reach similar effect, change the refractive index of this refraction part 232 so that its refractive index with this connecting portion 231 is different, for example: with the refraction part 232 that the big material of refractive index of this connecting portion 231 of refractive index ratio is made this lampshade 23, also can change light going direction and reach the effect of collected light.

By above-mentioned design, the utility model LED lighting device 2 has following advantage when reality is used:

(1) concentrate light:

The utility model is by the thickness adjustment of this refraction part 232, and the light that makes this LED element 222 send can be directed to predetermined direction, has significantly promoted the light directive property of this LED lighting device 2.In addition, this LED element 222 is to arrange near this depressed part 233, has reduced that light is advanced and the influence that is subjected to air refraction in air, can allow the particular design performance maximum effect of this lampshade 23, the better effects if that light is concentrated.

(2) elegant in appearance and reduce taking of height space:

The utility model forms the lampshade 23 of closed in order to reach the effect of concentrating light and this connecting portion 231, this refraction part 232 and this depressed part 233 are matched, and its profile can be the aspect of pisiform, red blood cell shape or jellyfish capitiform, but not as limit.And this lampshade 23 is designed to above-mentioned various aspect, not only form novel and beautiful, and make this lampshade 23 keep the condition lower compression whole height of circular arc lines, reduce taking of space, the bigger free degree of user and convenience also are provided on arranging.

(3) be convenient to maintenance:

Because this luminescence unit 22 is in the accommodation space 24 that is arranged at outside this lampshade 23, therefore, when needing to change if this LED element 222 breaks down, the utility model can provide the user easier maintenance mode, significantly promotes ease of use.

Consult Fig. 4, be second preferred embodiment of the utility model LED lighting device 2, and Fig. 4 is the profile of this second preferred embodiment.This second preferred embodiment and this first preferred embodiment are roughly the same, its difference be in: this LED lighting device 2 also comprises one and is arranged in this confined space 234 and the adjustment unit 25 in order to adjust light going direction.This adjustment unit 25 comprises and a pair ofly should refraction part 232 arranges and be connected with this refraction part 232, and in order to the adjustment part 251 of the light going direction of adjusting this LED element 222.In this preferred embodiment, the refractive index of these adjustment part 251 employed materials is greater than the refractive index of the connecting portion 231 of this lampshade 23, whereby to reach the effect of concentrating light.

By above-mentioned design, except making the light going direction changing of this LED element 222 by this adjustment part 251, and reach outside the effect identical with this first preferred embodiment, as long as the user selects the different adjustment part of refractive index 251 for use, just can design different light going directions, the direction adjustment of light can be changed to some extent, make the utility model in practical application, can have better adjustment elasticity and wide usage.

In sum, the utility model LED lighting device 2 changes or refraction index changing by the thickness of this refraction part 232, or the use of this adjustment part 251, just can adjust the light going direction of this LED element 222, reaches the effect of light source toward the predetermined direction guiding.In addition, further be positioned under this depressed part 233 by this LED element 222 and near this depressed part 233, the influence that not only can reduce light to advance in air and be subjected to air refraction has fault and when need changing, can provide easier maintenance mode again at LED element 222.In addition, the configuration design that this lampshade 23 is airtight can produce the visual experience of novel and beautiful in aesthetic feeling, can reach the purpose of this utility model really.
