Description

Technical Field

[0002] Optical lenses for LED lighting fixtures are optical components designed specifically for LED light sources. Their main function is to adjust, focus or diffuse the light beam emitted by the LED to achieve a specific lighting effect. They are usually made of transparent optical materials (such as glass or plastic). The surface morphology and design of the lens (such as spherical, parabolic, hyperbolic, etc.) will be optimized according to application requirements to control the propagation direction, brightness distribution and illumination range of light. The lens may include technologies such as microlens arrays, reflective layers or coatings to improve light efficiency and reduce light loss.

[0003] Optical lenses are used in LED lighting fixtures in the existing technology to focus or diffuse light beams and optimize lighting effects. However, LED light sources generate a large amount of heat during operation.

In addition, excessively high temperatures will also have an adverse effect on the optical lens. The lens material is prone to aging at high temperatures, the optical performance will be reduced, and deformation may even occur, causing damage to the lens itself, thereby affecting the performance and service life of the entire lighting system.

[0024] The technical solutions in the embodiments of the present invention will be described below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] See also Figure 1-5 The utility model is an optical lens structure for LED lighting fixtures, including a base 1, a lens body 2 is arranged on the top of the base 1, and a mounting plate 3 is arranged in the inner cavity of the base 1; a heat dissipation component is arranged in the inner cavity of the base 1, and the heat dissipation component includes a fixing plate 4, which is fixedly connected to the bottom of the base 1, and a fan 5 is fixedly connected to the inner cavity of the fixing plate 4. A bracket 6 is fixedly connected to the top of the fixing plate 4, and a heat exchanger 7 is fixedly connected to the top of the bracket 6. A circulation pipe 8 is connected to one end of the heat exchanger 7, and a heat sink 9 is fixedly connected to the top of the mounting plate 3; an efficiency improvement component is arranged in the inner cavity of the lens body 2, and the efficiency improvement component includes a projection cone 10, which is fixedly connected to the inner cavity of the lens body 2, a microlens array 11 is arranged on the top of the projection cone 10, an inner surface 12 is fixedly connected to the top of the projection cone 10, and a nano-optical coating 13 is bonded to the surface of the lens body 2.

[0027] Specifically: the mounting plate 3 is used to install the light source board 15, the fan 5 can extract the heat inside the base 1 to dissipate the heat of the LED light source 16, and the heat exchanger 7 and the circulation pipe 8 arranged on the top can obtain a certain auxiliary heat dissipation effect, and the heat sink 9 can absorb the heat in the LED light source 16 and the lens body, so that the cooling pipe 14 can centrally cool the heat inside the base 1.

[0028] The microlens array 11 disperses or focuses the light emitted by the light source through the refraction, reflection and diffraction of light. Through the design of this microlens array 11, the angle and shape of the light beam can be flexibly adjusted according to actual needs to avoid excessive concentration or excessive scattering of light. The nano-optical coating 13 has super hydrophobicity and can prevent dust from adhering to the surface of the lens body 2.

[0029] Example 2

[0030] See also Figure 1-5On the basis of Example 1, one end of the circulation pipe 8 is connected to the cooling pipe 14, the cooling pipe 14 is laid on the surface of the heat sink 9, and a solenoid valve is installed on the surface of the cooling pipe 14. A light source board 15 is provided on the top of the mounting plate 3, and an LED light source 16 is fixedly connected to the top of the light source board 15. A mounting ring 17 is fixedly connected to the top of the base 1. The inner cavity of the mounting ring 17 is provided with mounting holes all around. One end of the mounting hole extends to the inner cavity of the lens body 2. The inner cavity of the mounting hole is threaded with a bolt. A vent is provided at the bottom of the base 1, and a dustproof net 18 is fixedly connected to one side of the inner cavity of the vent. One side of the inner cavity of the vent is fixedly connected to one side of the fixing plate 4. A heat dissipation hole is provided at the bottom of the light source board 15. The heat dissipation hole is used to dissipate the heat of the LED light source 16 itself. Semicircular grooves are provided all around the surface of the light source board 15, and the surface of the bolt is slidably connected to the inner cavity of the semicircular groove.

[0031] Specifically: the cooling pipe 14 is laid in a ring on the surface of the heat sink 9, and the two sides of the surface are respectively connected to one end of the two circulation pipes 8 to facilitate the transportation of the coolant to the heat exchanger 7 for cooling. The heat exchanger 7 is an existing structure, which can draw the coolant in for cooling and return it to the cooling pipe 14. The size of the light source board 15 is slightly smaller than the inner cavity of the mounting ring 17, and the semicircular grooves opened around the surface can be limited by bolts during installation. The dustproof net 18 in the inner cavity of the vent can ensure that the inside of the base 1 is clean, and the heat generated by the LED light source 16 can be carried out of the base 1 by the wind blown out by the fan 5 through the heat dissipation holes.

[0032] The working principle of the present invention is as follows: when the optical lens structure for the LED lighting fixture is needed, the light source board 15 is first placed at the top center of the mounting plate 3, and then the lens body 2 is placed on the top of the mounting ring 17 at the top inside the base 1, and is installed by screwing bolts into the mounting holes. When the bolts are screwed in, the semicircular grooves around the light source board 15 can be limited, thereby limiting the LED light source 16.

[0033] When the lens body 2 is working, the microlens array 11 arranged inside can more accurately control the propagation path of light, achieve more precise light beam adjustment, and meet the light requirements in different application scenarios. The nano-optical coating 13 on the surface of the lens body 2 can reduce light reflection and loss, while improving the durability and cleanliness of the lens body 2, avoiding the problem of reduced light efficiency due to dust accumulation in the traditional lens body 2.

[0034] When the lens body 2 needs to dissipate heat inside the base 1 during operation, the coolant in the circulation pipe 8 is first circulated to the cooling pipe 14 through the solenoid valve. At this time, the heat sink 9 can absorb the heat generated by the LED light source 16 and the lens body 2, and the coolant in the cooling pipe 14 can cool down and dissipate heat to the heat sink 9. When the coolant circulates to the circulation pipe 8 at the other end, it flows into the heat exchanger 7 and can be cooled by the heat exchanger 7 for easy recycling. By starting the fan 5 through the external controller, auxiliary heat dissipation can be performed on the inside of the base 1, thereby completing the heat dissipation work of the LED light source 16 and the lens body 2.

[0035] When the lens body needs to dissipate heat inside the base during operation, the coolant in the circulation pipe is first circulated to the cooling pipe through the solenoid valve. At this time, the heat sink can absorb the heat generated by the LED light source and the lens body, and the coolant in the cooling pipe can cool the heat sink. When the coolant circulates to the circulation pipe at the other end, it flows into the heat exchanger and can be cooled by the heat exchanger for easy recycling. The fan is started by the external controller to assist in dissipating heat inside the base, thereby completing the heat dissipation of the LED light source and the lens body.

[0036] The standard parts used in the present invention can all be purchased from the market, and can be customized according to the description in the specification and drawings. The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the existing technology. The machinery, parts and equipment all adopt conventional models in the existing technology. The control method is automatically controlled by a control unit. The control circuit of the control unit can be implemented by simple programming by technicians in this field, which is common knowledge in this field. Therefore, the control method and circuit connection are no longer explained in detail in the present invention.
