A kind of LED light fixture optical texture

Technical field

The utility model relates to a kind of optical texture, especially a kind of LED light fixture optical texture.

Background technology

The light fixture product category is various, various informative, billboard Projecting Lamp for example, body of wall brightening Projecting Lamp, automobile video frequency monitoring flash lamp, the tunnel lamp of differing heights etc., the light fixture that these occasions are used is fully different to illumination zone and the requirement of light fixture, LED light fixture is on the market used LED light source in addition, then realizes luminous intensity distribution by the special-purpose lens of installing on LED light source, and light has certain light loss on by lampshade.

LED light source is efficient with it, energy-conservation, environmental protection, and the long-life, undersized advantage has been widely used in backlight, display device, room lighting, flood lighting etc.; Be accompanied by addition the development of industrial technology, glass or plastics molding process can directly be done some decorative patterns on plate material; So just can substitute the function of the special-purpose lens of LED on market fully with decorative pattern refracted ray on lampshade.

Light fixture product on market has no idea to use a set of shell to consider heat radiation, drive installation and waterproof, and lampshade is to the loss of light, therefore produced present technique, pass through simple reflector reflection ray and the lampshade decorative pattern refracted ray adjusted under a kind of fixing shell, can also be by increasing or reduce LED light source, reflector, and on lampshade, the quantity of optics pattern structure meets above all different lighting demands.

The utility model content

The purpose of this utility model is the deficiency existed for prior art, provides a kind of simple in structure, a kind of LED light fixture optical texture of low production cost.

For achieving the above object, a kind of LED light fixture of the utility model optical texture can adopt following technical scheme: a kind of LED light fixture optical texture, it comprises heat-dissipating casing, LED light source, LED light source circuit board, converge the reflector of LED light source light, and cover at the optical patterns on the lampshade of reflector top, it is characterized in that: described LED light fixture optical texture is used one group of LED light source one to one, reflector, with the optical patterns on lampshade, described optical patterns can be the concave surface decorative pattern, or the convex surface decorative pattern, or the Fresnel decorative pattern.

In prior art, compare, the utility model can carry out refracted ray by the decorative pattern on simple adjustment lampshade under a kind of fixing shell, meets specific region and angle, at a distance lighting demand.

The specific embodiment

Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand these embodiment and only for the utility model is described, be not used in restriction scope of the present utility model, after having read the utility model, those skilled in the art all fall within the application's claims limited range to the modification of the various equivalent form of values of the present utility model.

The utility model discloses a kind of LED light fixture optical texture 100, refer to Fig. 1, it comprises heat-dissipating casing 20, LED light source 30, LED light source circuit board 40, converge the reflector 50 of LED light source light, and the

optical patterns

601 or 602 that covers at correspondence on the lampshade 60 of reflector top, use the light of the light formation certain angle light intensity of reflector 50 reflection LED light sources 30, control again the refractive direction of light by the luminous intensity distribution

decorative pattern

601 or 602 on lampshade 60, thereby simple and easy and effectively control the lighting demand of light fixture in certain appointed area, described reflector 50 can be the parabola hyperbola, or elliptic curve, or whole polarisation reflecting surface, or several little polarisation reflecting surface summations, described reflector 50 can be fixed on circuit board 40, or be fixed on heat-dissipating casing 20, or on lampshade 60.

The first embodiment

Refer to Fig. 2 to Fig. 3, a kind of LED light fixture of the utility model optical texture mainly comprises aluminium section bar heat-dissipating casing 21, LED light source 41 is welded on aluminum base circuit board 31, and be screwed on shell 21, a sheathed reflector 51 on each LED light source, and use screw 71 to be fixed on aluminum base circuit board 31, lampshade 61 uses glue to be bonded on shell 21, guarantee spill decorative pattern 602 and the reflector 51 on lampshade 61 during design, and LED light source 41 keeps corresponding one by one, the inside ensuring that the driving 81 of light fixture is arranged at aluminium section bar heat-dissipating casing 21 drives 81 good seals.

The inner surface of described reflector 51 is coated with reflective membrane, and this reflective membrane can be the aluminium film, or silverskin, or the chromium film.
