Abstract
The invention relates to an LED lamp eliminating assistant light spots. The LED lamp comprises a light source and a reflection cup. An annular light convergence lens is arranged on the light exit surface of the reflection cup and used for converging light, not reflected by the reflection cup, at the edge of the light exit surface to the light spot center. According to the LED lamp, the formed assistant light spots are converged into main light spots through the light convergence lens, so that the utilization rate of the light source is increased, and the brightness of the main light spots is improved; under the cooperation of light of the two parts, output light is more effective.
Description
Technical field
The present invention relates to a kind of light fixture, particularly a kind of LED light fixture of cancelling secondary hot spot.
Background technology
LED light fixture is widely used in various aspects in life at present, because its energy-conservation, durable characteristic city makes it replace gradually conventional light source, but some specific occasion, to having relatively high expectations with the hot spot of LED light fixture, in existing LED light fixture on the market, be through the reflection of reflector and directly output to outside the reflexible angle of reflector because there is part light source, form secondary hot spot, as shown in Figure 1, can not the growing Lighting Design individual demand of consumer.
Summary of the invention
The object of the invention is the technological deficiency in order to overcome above-mentioned background.
A LED light fixture of cancelling secondary hot spot, comprises light source and reflector; The exiting surface place of described reflector is provided with receipts optical lens, and circlewise, described receipts optical lens draws in to spot center without described reflector reflection ray described exiting surface edge described receipts optical lens.
Further right, the incidence surface of described receipts optical lens is the concentric circular ridge of multi-turn.
Further, the cross section of described circular ridge is triangular shape, it comprises the second surface that optical plane tilts that enters perpendicular to the first surface that enters optical plane of described receipts optical lens and relative described receipts optical lens, described first surface is transmission plane, described second surface is fully reflecting surface, incident light reflects to enter and receives in optical lens after the first surface of described circular ridge, and by after described second surface total reflection, penetrates through the exit facet of described receipts optical lens body.
Further, the height of described circular ridge has the optical lens edge of receipts to reduce gradually to center.
The beneficial effect that the present invention plays:
Drawn in main spot by the secondary hot spot of design forming of receiving optical lens, improved the utilization rate of light source, strengthened the brightness of main spot simultaneously. This two-part light cooperatively interacts, and makes exported light more effective.
Brief description of the drawings
Fig. 1 is the light path principle figure of prior art.
Fig. 2 is the blast structure chart in the embodiment of the present invention.
Fig. 3 is the profile of the receipts optical lens in the embodiment of the present invention.
Fig. 4 is the light path principle figure of the embodiment of the present invention.
Detailed description of the invention
In order to allow those skilled in the art more understand technical scheme of the present invention, below in conjunction with the drawings and specific embodiments, the LED light fixture of the secondary hot spot of cancellation of the present invention is further described.
Prior art as shown in Figure 1, conventionally under the cooperation of light source and reflector, its output light has comprised two parts, a part is the light that light source is not directly exported through the reflection of reflector, another part is the light of exporting again after reflector reflection, conventionally the overlapping part of this two parts light has formed main spot, and in the light of directly exporting, periphery has formed secondary hot spot, due to the existence of secondary hot spot, the Code in Hazardous Special Locations of high request is used and missed fire, can not meet the Lighting Design individual demand such as hotel, shop.
Impact and the defect brought in order to eliminate above-mentioned secondary hot spot, the invention provides a kind of LED light fixture of cancelling secondary hot spot, as shown in Figure 2, comprises radiator 1, light source 2, reflector 3, receives optical lens 4 and shell 5; Wherein light source 2 is arranged on radiator 1, and the incidence surface of reflector 3 is provided with the through hole coordinating with described light source 2. After through hole overlaps therein by light source 2, reflector 3 is fixedly connected with radiator 1, and the light that the light source 2 making produces can only be reflected or directly be penetrated through after reflector by reflector 3. Receipts optical lens 4 is arranged on the exiting surface place of reflector 3 front ends. By shell 5, reflector 3 and receipts optical lens 4 are fixed.
Aspect receipts optical lens 4, receive optical lens 4 circlewise, it comprises incidence surface 41 and exiting surface 42, its light reflecting without described reflector 3 by reflector 3 exiting surface edges draws in to spot center.
Concrete, the incidence surface 41 of receiving optical lens 4 is the concentric circular ridge of multi-turn 43. In the present embodiment, as shown in Figure 3 and Figure 4. The cross section of circular ridge 43 is triangular shape, it comprises perpendicular to receiving the first surface that enters optical plane 431 of optical lens 4 and the second surface 432 that optical plane tilts that enters of relative receipts optical lens, first surface 431 is transmission plane, second surface 432 is fully reflecting surface, incident light reflects to enter and receives in optical lens 4 after the first surface 431 of circular ridge 43, and by after second surface 432 total reflections, penetrate through the exiting surface of receiving optical lens 4 bodies. Wherein, the angle between first surface 431 and second surface 432 is between 30 ° to 60 °, preferably 40 °.
In addition, receive light effect in order further to improve, the height of circular ridge 43 has optical lens 4 edges of receipts to reduce gradually to center.
By reference to the accompanying drawings embodiments of the present invention are explained in detail above, but the present invention is not limited to above-mentioned embodiment, in the ken possessing those of ordinary skill in the art, can also under the prerequisite that does not depart from aim of the present invention, makes various variations.
