Abstract
The invention discloses an optical lens for a light-emitting diode (LED) lamp. The optical lens for the LED lamp comprises a lens body, a light-shading fixing block facilitating fixing of the lens body is outward arranged on the peripheral edge of the top end of the lens body, a plurality of fixing cylinders facilitating the fixing of the lens body are arranged on the bottom face of the lens body, and the bottom face of the lens body is provided with a pit for accommodating an LED lamp. The top and the wall face of the pit are incident planes, the peripheral face of the lens body is an outward protruding arc-shaped face and is a full-reflection face, the upper surface of the lens body is an emergence face, and the emergence face comprises a spherical surface protrusion at the central position, a cambered surface protrusion arranged around the spherical surface protrusion and a plane portion arranged around the cambered surface protrusion. The pit is a cylindrical pit, and the top of the pit is a downward protruding spherical surface recess. The optical lens for the LED lamp is reasonable and ingenious in structural design, enables light emitted by an LED light source to be soft and even in use and can effectively reduce light loss, improve the luminous efficiency and enlarge the irradiated area.
Description
Technical field

Background technology
Led light source has energy-saving and environmental protection, remarkable advantage such as efficient, thereby worldwide obtains very big applying.But because little, the shortcomings such as light efficiency is low, price height of past led light source power, and the not high lamp factor of the efficiency of light energy utilization, so limited the scope of application of led light source, usually led light source just is applied to low side fields such as traditional signal indication and family expenses flashlight, influences and limited its development and popularization.Therefore, the research and development of the optical lens that high-powered LED lamp, particularly LED lamp are used and commercial application thereof seem more urgent and important.
The existing LED lamp optical lens of seeing on the market, often because of its each dimensional parameters design rationally perfect inadequately, it is serious to cause not reaching soft illumination purposes and light loss, present be one dazzling and the spot light of hot spot arranged, light emission rate is low, and irradiated area is little, has influenced use.
Summary of the invention
The objective of the invention is to, at the problems referred to above, the optical lens that provides a kind of LED lamp to use, its reasonable in design is ingenious, and by the use of this optical lens, the light that led light source is sent is soft evenly, light loss be can effectively reduce, light extraction efficiency and irradiated area improved.
The technical scheme that the present invention adopts for achieving the above object is:
The optical lens that a kind of LED lamp is used, it comprises lens body, this lens body top week is along outwards being provided with the shading fixed block of being convenient to fix this lens body, the bottom surface of this lens body is provided with some fixed cylinder of being convenient to fix this lens body, the bottom surface of this lens body is provided with a pit for ccontaining LED lamp, the top of this pit and wall are the plane of incidence, the side face of this lens body is an arcwall face to outer lug, this side face is fully reflecting surface, the upper surface of this lens body is exit facet, this exit facet comprises the spherical surface hill of center, around the cambered surface projection of this spherical surface hill setting and the planar portions that arranges around this cambered surface projection, this pit is a cylindrical pit, the top of this pit is a sphere depression to lower convexity, the diameter of this pit is 19cm, distance between the bottom of this sphere depression and the bottom surface of lens body is 5cm, the bottom of this spherical surface hill and the distance between the top are 6cm, the diameter of this spherical surface hill bottom surface is 20cm, the top of this cambered surface projection is 7cm to the distance between the bottom, and the distance between the top of this cambered surface projection and the lens body axis is 22cm.
The diameter of this lens body bottom surface is 31cm, and the distance between this arcwall face top and the lens body axis is 26cm.
This planar portions outer diameter is 52cm.
Described fixed cylinder is two, and this two fixed cylinder axis of this lens body relatively is symmetricly set on the bottom surface of this lens body.
Exit facet has carried out the frosted processing.
Shading treatment has all been carried out on the upper and lower surface of this shading fixed block.
By the test of limited number of times, can obtain the radius of the preferable result of use of various arcwall faces, sphere.
Beneficial effect of the present invention is: its reasonable in design of the present invention is ingenious, and by the use of this optical lens, the light that led light source is sent is soft evenly effectively to reduce light loss, improves light extraction efficiency and irradiated area.
Below in conjunction with accompanying drawing and embodiment, the present invention is further described.
