A kind of double hump shape led light source

Technical field

The utility model relates to the led light source field, is meant a kind of double hump shape led light source especially.

Background technology

Led light source is as a kind of semiconductive luminescent materials, has good, the luminous advantage such as stable of energy-saving and environmental protection, colour rendering, compares with other light source, will progressively substitute conventional light source with its green, efficient, reliable, durable advantage.The LED street lamp is a plurality of high-power LED light source combinations, and adopt the plane lattice form to distribute, carry out the secondary optics luminous intensity distribution by external lens or reflector, the distribution of control light, the light that sends becomes a strip light belt and distributes along the road surface, satisfies the demand of road lighting.

With reference to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, the cap a of tradition led light source is center symmetric shapes such as circle, the distribution curve flux of this light source is centrosymmetric, the Illumination Distribution that light source shines on the road surface is circle, in order to meet the requirement of street lighting to illumination range, luminosity curve, will outside the LED light fixture, set up lens, install speculum additional or with the light source angle mount, these measures have following shortcoming:

One, no matter set up lens or install speculum additional, all will produce the light loss consumption, reduce the brightness of light source;

Two, no matter set up lens or install speculum additional, the thickness of light fixture will be increased, increase the light fixture cost;

Three, with the light source angle mount, complex structure also must increase cost.

The utility model content

The cap that main purpose of the present utility model is to overcome led light source in the prior art is the shortcoming that center symmetric shapes such as circle are brought, and a kind of double hump shape led light source is provided.

The utility model adopts following technical scheme:

A kind of double hump shape led light source comprises that a matrix and is encapsulated in the cap on this matrix, and this cap is the double hump shape structure.

According to a better embodiment of the present utility model, have a first axle and one second axis on the described cap, this first axle passes two humps of this cap and this cap with respect to this first axle axisymmetricly, this second axis and this first axle is perpendicular and this cap with respect to this second axis axisymmetricly.

According to a better embodiment of the present utility model, the both sides that described cap is passed by described second axis are the shape structure linearly.

According to a better embodiment of the present utility model, described cap is caved inward by the both sides that described second axis passes.

According to a better embodiment of the present utility model, the length of described first axle is greater than the length of described second axis.

According to a better embodiment of the present utility model, two humps of described cap are level and smooth curved body structure.

By above-mentioned to description of the present utility model as can be known, compared with prior art, a kind of double hump shape led light source of the present utility model has following advantage:

One, the cap of the utility model led light source is the double hump shape structure, and the luminous intensity distribution of led light source is non-centrosymmetrical " bat is wing ", and vertical irradiation is approximate oblong to the illumination on the road surface, and irradiated area is bigger, is fit to very much road lighting;

Two, the street lamp that adopts the utility model double hump shape led light source is not owing to need to install additional lens or reflector, and light source can not produce loss, and can reduce production costs;

Three, adopt the street lamp of the utility model double hump shape led light source owing to do not need to install additional lens or reflector, the space thickness of street lamp itself reduces, weight saving;

Four, compare with the street lamp that adopts traditional led light source, adopt the street lamp of the utility model double hump shape led light source because irradiated area is bigger, the required street lamp of same road segment is less, reduces use cost;

Five, adopt the street lamp design difficulty of the utility model double hump shape led light source lower.

The specific embodiment

Below the utility model will be further described by the specific embodiment.

The specific embodiment one

With reference to Fig. 5, Fig. 6 and Fig. 7, a kind of double hump shape led light source of the present utility model comprises a matrix 1 and the double hump shape cap 2 that is encapsulated on this matrix 1.

Have a first axle 21 and one second axis 22 on the cap 2, this first axle 21 passes two humps of this cap 2 and this cap 2 with respect to this first axle 21 axisymmetricly, perpendicular and this cap 2 of this second axis 22 and this first axle 21 with respect to this second axis 22 axisymmetricly, the length of first axle 21 is greater than the length of second axis 22.

Cap 2 is caved inward by the both sides 23 that second axis 22 passes.

Two humps of cap 2 are level and smooth curved body structure, can improve the illumination uniformity of led light source of the present utility model.

With reference to Fig. 8 and Fig. 9, the luminous intensity distribution of the utility model double hump shape led light source is non-centrosymmetrical " bat is wing ", and vertical irradiation is approximate oblong to the illumination on the road surface, and irradiated area is bigger, is fit to very much road lighting.

The specific embodiment two

With reference to Figure 10 and Figure 11, the principle of this specific embodiment and the specific embodiment one is basic identical, and difference is: the both sides 23 that cap 2 is passed by second axis 22 are the shape structure linearly, and correspondingly its distribution curve flux also changes contrast.

Above-mentioned only is two specific embodiment of the present utility model, but design concept of the present utility model is not limited thereto, such as:

One, though the specific embodiment one and the specific embodiment two all define cap 2 with respect to first axle 21 and second axis 22 axisymmetricly, but this mainly is the even preferred a kind of mode of illumination in order to guarantee led light source, can not limit the utility model with this, according to the specific demand of different occasions, can do certain variation;

Two, two humps of cap 2 are level and smooth curved body structure, are a kind of preferred modes that improves the illumination uniformity of led light source of the present utility model, but can not limit the utility model with this;

Or the like, in a word, allly utilize this design that the utility model is carried out the change of unsubstantiality, all should belong to the behavior of invading the utility model protection domain.
