Description

The light-guide rod structure of LED candle lamp

Technical field

The utility model relates to a kind of LED candle lamp, especially a kind of lamp guide of LED candle lamp.

Background technology

LED(Light Emitting Diode, light emitting diode) be a kind of solid-state semiconductor devices that can be electric energy conversion directly luminous energy.LED is because the advantages such as its low-power consumption, high luminous efficiency and life-span be stable are widely used in productive life.Its profile of LED candle lamp is similar to candle flame and can produce the light atmosphere of similar candle, for building warm atmosphere thereby being subject to people, welcomes.

The lamp guide of existing LED candle lamp has multiple, but can be classified as two large classes: a class is that lamp guide is to make with transparent material fully, and profile and candle are approximate, as Fig. 1 a, Fig. 1 b and Fig. 1 c are depicted as the light-guide rod structure of the existing LED candle lamp of this class.The lamp guide of this LED candle lamp is made into integration by light-transmitting materials (as acrylic/PC), the lamp guide top be provided with the depressed part 1 of a taper ', its light distribution angle is less than 180 degree, reflex to rear light less, it is darker that rear seems, can't reach the atmosphere effect of the lighting angle of candle 270 degree.

Another kind of is that the top of cylindric lamp guide is provided with the taper concave face, as Fig. 2 a, Fig. 2 b and Fig. 2 c are depicted as the light-guide rod structure of the existing LED candle lamp of this class.The lamp guide of this LED candle lamp is also to be made into integration by light-transmitting materials (as acrylic/PC), the top of lamp guide be provided with the depressed part 2 of a taper ', and depressed part 2 ' the conical surface be coated with reflectance coating.It goes back to the light reflection in the place ahead to rear by reflectance coating, builds 270 degree lighting angles of similar candle.Therefore although light emitting anger reaches the effect of candle light, thereby its dead ahead has the phenomenon of shadow to affect light distribution effect, equally also Shortcomings.

The utility model content

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of LED distribution light beam angle of flare that not only can enlarge is provided, and also can eliminate the light-guide rod structure of the LED candle lamp of LED shadow phenomenon.

For achieving the above object, the utility model is by the following technical solutions:

The light-guide rod structure of LED candle lamp, comprise

The light conductor that light-transmitting materials is made, described light conductor is that diameter becomes large cylinder from top to bottom gradually, the top of described light conductor forms a depressed part;

The reflector stud that reflective material is made, described reflector stud forms cone and is fixed on the center of described depressed part by the tip of its cone;

Be positioned at the Connection Block of described light conductor bottom, its bottom is formed for the accommodating cavity of accommodating LED lamp holder.

Be coated with reflective metal film on the conical surface of described reflector stud.

The top end diameter of described reflector stud is less than the minimum diameter of described light conductor.

The distance on the top end face of described reflector stud and described light conductor top is 1～3cm.

Preferably, the distance on the top end face of described reflector stud and described light conductor top is 2cm.

After adopting technique scheme, the utility model is compared with existing background technology, there is following advantage: structural design luminous image of similar common tengsten lamp on external form that the utility model lamp guide adopts, reflector stud not only can make the refraction of LED light by lamp guide realize LED light 270 degree or larger lighting angles, and angle of flare is more even, also can avoid occurring shadow.

The specific embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.

Embodiment

As Fig. 3 a, Fig. 3 b and Fig. 3 c are depicted as the light-guide rod structure of the utility model LED candle lamp, lamp guide integral body is placed on LED lamp holder (not shown), for changing the radiation direction that the LED lamp holder sends, lamp guide comprises light conductor 1, reflector stud 2 and Connection Block 3.

Light conductor 1 is made by light-transmitting materials, and it becomes large cylinder from top to bottom gradually for diameter, and the top of light conductor 1 forms a depressed part 11, and depressed part 11 can be taper, can be also the inner sunken face formed by irregular curve, sees Fig. 3 c.

Being located at the reflector stud 2 at light conductor 1 top is made by reflective material, reflector stud 2 is a cone, tip 21 by its cone is fixed on depressed part 11 center, the top of reflector stud 2 is plane or hemisphere face, can be for inscribing Logo, the diameter on its top is less than the minimum diameter of light conductor 1, and its bus 22 that forms cone can be straight line or curve, the light that reflector stud 2 appears through light conductor 1 for reflection.

Connection Block 3 is positioned at the bottom of light conductor 1, and Connection Block 3 bottoms are formed for the accommodating cavity 31 of accommodating LED lamp holder.

The light-transmitting materials of light conductor 1 can adopt the materials such as glass, acrylic, transparent plastic, and reflector stud 2 can directly adopt reflective plastic production, also can on the conical surface, plate the layer of metal reflective membrane.

The distance on the top end face of reflector stud 2 and light conductor 1 top is 1～3cm, be preferably 2cm, the light that light conductor 1 sends for the LED lamp holder that receives and reflect from bottom, the light that light conductor 1 appears can be through reflector stud 2 reflections, and light also reflects away from the space formed between reflector stud 2 and light conductor 1, its light sent directive all directions have all sidedly been realized, not only be conducive to the diffusion of light wide-angle, distribution of light is more even, nor can produce the shadow zone, the contrast of the visible following light distribution curve figure of concrete effect.

The light distribution curve figure of the lamp guide that Fig. 4 is the LED candle lamp shown in Fig. 1 a, Fig. 1 b and Fig. 1 c, its beam angle reaches 150 degree, and the light skewness.

The light distribution curve figure of the lamp guide that Fig. 5 is the LED candle lamp shown in Fig. 2 a, Fig. 2 b and Fig. 2 c, its beam angle reaches 180 degree, and the shadow zone is arranged.

Be illustrated in figure 6 the light distribution curve figure of the lamp guide of LED candle lamp of the present utility model, beam angle can reach 270 degree.

From the contrast of above-mentioned light distribution curve figure, can clearly be seen that the beam spread angle that can make LED of light-guide rod structure of candle lamp of the present utility model is larger, distribution of light is more even, more approaches the light atmosphere of true candle.

The above; it is only the preferably specific embodiment of the utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
