Abstract

The utility model discloses a light source generating with improved structure, comprising an LED arranged at the back end of a housing and an optical fiber arranged at the front end of the housing. The end part of the optical fiber is sheathed and arranged in a fixed head which is sheathed and arranged in a lumen at the front end of the housing. The LED is arranged on the circuit board which is arranged in a lumen at the back end of the housing. A controller is arranged at the back end of the circuit board, and the end cover is fixed on the housing by a blot. The back part of the housing is provided with a line outlet hole which can be arranged as a power input jack. A final-position convex rib is arranged between the optical fiber at the front end of the housing and the LED at the back end of the housing. When a plurality of LEDs are arranged, an arc translucent cover with uniform thickness is arranged between the final-position convex rib and a reflecting ring in order that the light rays generated by the plurality of LEDs can uniformly beat down on the end face of the optical fiber arranged in the fixed head. The utility model has the advantages of low caloric power, low cost and good decorative effect.

Description

A kind of structure improved light source generator

Affiliated technical field

The utility model relates to a kind of illumination and decoration device, particularly a kind of structure improved light source generator.

Background technology

Optical fiber is except that being used as communication, at present also as decorating, come conducting light to have the conduction efficiency height with optical fiber, safety, etc. characteristics, for this reason, have the inventor to invent a kind of patent No. to be: ZL97209717.1, name is called " a kind of light source generator ", this light source device is by light source, optical fiber and optical fiber is head fixedly, color chips, motor is formed, but the illuminator of the optical fiber source that is used as all is a bulb at present, and be single bulb, glow color is single, when sending multiple color, must adopt by need motor to drive color chips, and exist the illuminator heating high, the shortcoming that cost is high, the easy variable color of optical fiber head when its service time is long, and because illuminator is a bulb, so spotlight effect is poor, thereby there is the shortcoming of decorative effect difference.

Summary of the invention

The purpose of this utility model is in order to overcome the defective of above-mentioned existence, provides that a kind of caloric value is low, cost is low, the structure improved light source generator of good decorating effect.

The technical solution adopted in the utility model is a kind of structure improved light source generator to achieve these goals, mainly comprise optical fiber, shell, light source, described light source is LED, this LED is arranged on outer casing back, described optical fiber is provided with the shell front end, is provided with position-arresting convex rib between the optical fiber of described shell front end and the LED of outer casing back.

Be provided with the uniform camber translucent cover of a thickness between described LED and the position-arresting convex rib.

The rearward end of described shell is provided with one controller.

Be provided with a taperedchromeplatedbezel between described LED and the camber translucent cover.

A kind of structure improved light source generator of the utility model compared with prior art its beneficial effect has:

1. owing to adopt LED as illuminator, caloric value is low, the advantage of long service life thereby have.

2. has the camber translucent cover that light is evenly dispersed uniformly owing between LED and position-arresting convex rib, be provided with a thickness, its LED is luminous by the controller control that is arranged on outer casing back portion, thereby can send the light of multiple color, and between described LED and camber translucent cover, be provided with a taperedchromeplatedbezel, thereby have good decorating effect, advantage that cost is low.

The specific embodiment

Below in conjunction with the drawings and the specific embodiments the utility model is done

With reference to Fig. 1,2, the utility model comprises the LED31 that is arranged on shell 1 rear end 11, and the optical fiber 2 of shell 1 front end 12 is set, the end of described optical fiber is nested with in one fixing 21, be fixed then and 21 be nested with in the tube chamber of shell front end 12, its LED31 is arranged on the circuit board 3, and this circuit board is arranged in the tube chamber of outer casing back 11, and then controller 42 is installed in the rear end of circuit board 3, its controller 42 can be arranged on the end cap 4, also can be arranged on another circuit board separately, its end cap 4 is fixed on the shell 1 by screw 41, be provided with the wire hole 13 of a power line 7 in the rearward end 11 of shell 1, change wire hole and can be set to the power supply input jack.

With reference to Fig. 3,4, be provided with a position-arresting convex rib 14 between the optical fiber of described shell front end and the LED of outer casing back, its position-arresting convex rib 14 is mainly used in backstop and is arranged on fixedly head of shell front end 12 intraluminal optical fiber, and will be arranged on outer casing back 11 intraluminal LED and fixing (not shown) that keeps at a certain distance away of optical fiber, thereby the light that LED is sent can diffuse to the end face that is arranged on the fixing inner fiber of optical fiber equably, then light is conducted.It is used to install the circuit board of LED by being arranged on step 5 backstops at middle part in shell 1 tube chamber.

With reference to Fig. 5, when the LED in the utility model is set to when a plurality of, can shine the end face that is arranged on the fixing inner fiber of optical fiber equably for the light that a plurality of LED are sent, position between LED and position-arresting convex rib 14 is provided with the uniform camber translucent cover 6 of a thickness, the particular location of its camber translucent cover can be between position-arresting convex rib 14 and taperedchromeplatedbezel 52, described translucent cover 6 can be glass material or plastic material, because its translucent cover 6 is protruding end faces to the fixing inner fiber of optical fiber, parallel again exhaling after so the light that its LED sends converges by translucent cover, because light is to disperse equably, thereby the brightness that is arranged on each strand optical fiber of the fixing inner fiber of optical fiber is all compared evenly, also just part optical fiber can not occur exhales more weak light, and part part optical fiber exhales stronger light, owing between position-arresting convex rib 14 and taperedchromeplatedbezel 52, be provided with the uniform camber translucent cover 6 of a thickness, thereby avoided the shortcoming of the inhomogeneous decorative effect difference that causes of divergence of beam effect that occurs in the existing light source device.Described taperedchromeplatedbezel 52 can be set to independent parts, and taperedchromeplatedbezel 52 inner surfaces are provided with reflector layer 51.Its taperedchromeplatedbezel 52 can be set to one with shell, is installed between position-arresting convex rib and the taperedchromeplatedbezel in order to make translucent cover, thereby also can be set to independent parts by position-arresting convex rib, so just translucent cover can be installed in the enclosure smoothly.

Above illustrated embodiment only in order to convenient explanation the utility model, is not breaking away from creation spirit category of the present utility model, is familiar with the various simple and easy covert and modification that the personage did of this technology, still should be included in the technical solution of the utility model scope.
