Abstract
The utility model relates to a light-emitting diode (LED) lamp, in particular to a semi-sphere embedded LED down lamp. The semi-sphere embedded LED down lamp structurally comprises a down lamp face ring, a semi-sphere light-transmitting cover is fixed below the inside of the down lamp face ring, a circuit board is clamped above the down lamp face ring, an LED lamp bead is arranged below the circuit board, and a radiator and a driver are connected onto the circuit board. Compared with the prior art, the semi-sphere embedded LED down lamp has the advantages of being simple in structure, remarkable in use effect and high in lighting effect and saving raw materials.
Description
Technical field
The utility model relates to a kind of LED light fixture, and a kind of dome-type embedded LED down lamp specifically is provided.
Background technology
LED light fixture under the prior art especially embeds the LED light fixture in the ceiling, and it generally has following three kinds:
1, embedded simple lamp: be a kind of lighting that is embedded into light down-ejection type in the ceiling, 1. its constitutional detail has 2. 3. 4. 5. 6. 7. down lamp bracket shell fragment of reflector shell fragment of E27 lamp holder of Down lamp base of down lamp bracket of reflector of Down lamp face ring, complex structure, the waste raw material, can not use separately, want supporting corresponding light source, its lighting theory is that light source passes through reverberation cup refracted ray, light is concentrated luminous one-way, only have its opposite just can be subjected to light, and the light beam angleplied laminate belongs to optically focused, light is more concentrated, comparison of light and shade is strong, easily produces half-light, causes that vision is weak.The irradiating angle of Down lamp is less than 90 degree.
2, LED Down lamp: be a kind of embedded illuminating product to the interior light down-ejection type of Ceiling light, 1. its constitutional detail has 2. 3. 4. 5. 6. 7. plane light-transmission cover of led light source driver of radiator of light source part of reflector of down lamp bracket of Down lamp face ring, the result of use shortcoming has, use the reflector refracted ray, the loss optical efficiency, only have opposite to be subjected to light, light-emitting window is subject to the areal extent of plane light-transmission cover, light-receiving area is little, the refraction angle of reflector and the light loss of refraction, the plane light-transmission cover does not have the effect of diffused light, and irradiating angle is less than 90 degree.
3, LED Ceiling light: claim again the LED smallpox shot-light, detail of construction have 1. smallpox face ring 2. the face ring support 3. radiator encircle 5. 6. 7. optical lens of light source drive of light source part in 4., its lighting theory is that LED light passes through optical lens, after twice refraction, make parallel rays that a convergent point is arranged, light becomes direct projection light behind the scioptics, and lens on light has the converging ray effect.Its shortcoming: 1. luminous one-way, only have opposite to be subjected to light.2. light is by behind the optical lens, and light is more concentrated, and comparison of light and shade is strong within sweep of the eye, the luminance difference at background and center, the visual field is larger, easily produces dazzle, and dazzle easily causes visual fatigue or directly injures eyes, the scioptics light-ray condensing, an existence specific aim local lighting.
Summary of the invention
The utility model is for above problem, and a kind of dome-type embedded LED down lamp is provided, and it is luminous that it changes into sphere with the LED point light source light-emitting, by the mode of dome-type diffuser with the diffuse refraction of LED light, increases light-emitting area, reaches the shortcoming of eliminating above product.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of dome-type embedded LED down lamp, comprise Down lamp face ring, below, Down lamp face ring inside is fixed with the dome-type diffuser, and described Down lamp face ring top fixes wiring board, described wiring board below is provided with LED lamp pearl, and described wiring board top is connected with radiator and driver.
Down lamp face ring both sides are provided with down lamp bracket.
A kind of dome-type embedded LED letter lamp of the present utility model, using the dome-type diffuser instead, that the LED point light source light-emitting is changed into sphere is luminous, increase light-emitting area, led light source is by the dome-type diffuser, mode directive all directions with the light diffuse refraction, give people's visual effect soft evenly, irradiating angle is greater than 180 degree.
Use principle is: it is luminous that the dome-type diffuser changes into sphere with the LED spot light by the dome-type diffuser, indirectly increases light-emitting area, and light shines to all directions in the mode of diffuse refraction, reaches the utilization that improves light, and effect is soft, even.
A kind of dome-type embedded LED down lamp of the present utility model, simple in structure, result of use is remarkable, and light efficiency is high, saves raw material.
Description of drawings
Fig. 1 is a kind of perspective view of dome-type embedded LED letter lamp;
Fig. 2 be a kind of dome-type embedded LED down lamp partly cut open structural representation.
The specific embodiment
Below in conjunction with the drawings and specific embodiments a kind of dome-type embedded LED letter lamp of the present utility model is further described.
Shown in accompanying drawing 1,2, a kind of dome-type embedded LED down lamp, comprise Down lamp face ring 1, Down lamp face ring 1 inner below is fixed with dome-type diffuser 2, described Down lamp face ring 1 top fixes wiring board 3, described wiring board 3 belows are provided with LED lamp pearl 4, and described wiring board 3 tops are connected with radiator 5 and driver 6.
Down lamp face ring 1 both sides are provided with down lamp bracket 7.
Above-described embodiment, the utility model specific embodiment a kind of more preferably just, the common variation that those skilled in the art carries out in the technical solutions of the utility model scope and replacing all should be included in the protection domain of the present utility model.
Claims (2)
1. dome-type embedded LED down lamp, comprise Down lamp face ring, it is characterized in that, below, described Down lamp face ring inside is fixed with the dome-type diffuser, described Down lamp face ring top fixes wiring board, described wiring board below is provided with LED lamp pearl, and described wiring board top is connected with radiator and driver.
2. a kind of dome-type embedded LED down lamp according to claim 1 is characterized in that, described Down lamp face ring both sides are provided with down lamp bracket.
