Description
Technical field
The utility model relates to and a kind ofly is used to throw light on, the light-emitting device of decorative use, specifically a kind of strip light-emitting device.
Background technology
Based on the reason of service life, use light emitting diode (LED) to become general trend at present as the light source of purposes such as illumination, caution or decoration than long and power saving.With the 3rd brake lamp of automobile, normally a plurality of LED are arranged in a straight line, in the time of braking automobile, it is luminous to touch these LED of circuitorder, uses to reach warning function.In addition, the lampion in general brake lamp, indicator or the car of automobile also gradually adopts LED as light source.
Yet, because the intensity of light of single LEDs is limited, therefore, need plurality of LEDs to form a light fixture usually, also can't reduce cost because the used LED quantity of one group of light fixture is more.In addition, directly use LED, the light that is sent is not softer yet.
Summary of the invention
The purpose of this utility model is to design a kind of strip light-emitting device of throwing light on, decorating of being used to.
To be solved in the utility model is that existing LED light fixture need be used plurality of LEDs, and can't reduce cost and and the also not softer problem of light.
The technical solution of the utility model is: it comprises and is provided with a light source in two light source bases, each light source base at least, between two light source bases, be provided with lamp guide, two ends of lamp guide are connected with two light source bases respectively, and the ray cast of light source is in two ends of lamp guide; Surface distributed at lamp guide has reflective spot, and these reflective spot distribution densities are from increasing gradually toward leaving light source direction near light source.
Another technical scheme of the present utility model is: it comprises and is provided with a light source in a light source base, a cap, the light source base at least, be provided with reflecting piece in the cap, be provided with lamp guide between cap and the light source base, two ends of lamp guide are connected with light source base with cap respectively, and source light throws toward the cap direction from an end of lamp guide; Surface distributed at lamp guide has reflective spot, and these reflective spot distribution densities are from increasing gradually toward leaving light source direction near light source.
The utility model advantage: the one since with single or a spot of LED as light source, axially project light from two ends or an end of a microscler lamp guide, make part light directly penetrate lamp guide, part light further by lamp guide be located at the lamp guide part gradually the reflective spot of density reflect lamp guide, make that the whole piece lamp guide produces evenly, soft light; The 2nd, in addition, inject lamp guide behind the light source planoconvex lens light harvesting owing between the end of lamp guide and light source, convex lens are set, make the whole piece lamp guide produce soft more uniform light; The 3rd, but owing to the matsurface that is provided with refractive power in the region surface of lamp guide transmitted light, also can impel lamp guide to send brighter and soft light.
