Abstract
The utility model relates to a luminous diode LED flashlight, in particular to a lamp cap structure of the LED flashlight. Based on an original set of LED light source, the utility model mainly provides a luminous diode LED and a small optical collector (12), and thereby increases the illuminating brightness; meanwhile, a baffle with glistening effect is arranged so that partial lights scattered originally are reflected to the convergent surface on the optical collector through the baffle, and further to effectively utilize the illuminating object. The structure effectively increases the lamp cap space of the LED flashlight and the light use rate, and therefore has the advantages of simple structure, remarkable brightening effect, and low cost, etc., especially easy for popularization.
Description
Technical field
The utility model relates to a kind of holder structure of a kind of LED (light emitting diode) flashlight, especially LED flashlight.
Background technology
LED is a kind of cold light source of low energy consumption, and the LED flashlight uses more and more widely in real life, and the white light that LED sends is transferred clearly than the inclined to one side yellow that conventional incandescent bulb sends.The battery of LED flashlight, switch, circuit be basically identical all, and the utilization rate of the light that LED sends depends primarily on the structural design of lamp holder.In the prior art, adopt plurality of LEDs to be evenly distributed on the base at cup center, the end of prefocus cup as the LED torch lamp is first, the light that LED sends is reflected in parallel substantially by the caustic surface on the prefocus cup and goes out, wherein a part of light on the prefocus cup caustic surface and directly scatter out, do not form effective lighting, have the low problem of utilization rate.In addition, also be not utilized effectively in the prefocus cup centre position, LED structural configuration shortcoming causes the not good of illuminating effect.
Summary of the invention
The purpose of this utility model is a kind of rational in infrastructure, LED flashlight lamp holder that utilization rate is high, energy-conservation of design, mainly is that the holder structure at the LED flashlight improves.The technical solution of the utility model is so to realize:
LED torch lamp header structure, comprise the prefocus cup cup, wiring board, lamp socket and one group of LED provided thereon, the top of one group of LED (2) is provided with the plate washer (3) that is fixedly connected with lamp socket, be provided with little prefocus cup (12) and a LED (12) vertical with one group of LED (2) in the prefocus cup cup (1), plate washer (3) is fixedly connected with little prefocus cup (12).
As preferably, the opening-like half spindle of little prefocus cup (12), opening direction is consistent with prefocus cup cup (1), and opening diameter is less than plate washer (3) external diameter.
As preferably, plate washer (3) is a discoid body, and the mask of nearly LED (2) has reflection action, and the part light that LED (2) can be come out reflexes on the caustic surface (4) of prefocus cup.
As preferably, the diameter of a circle that plate washer (3) external diameter forms greater than one group of LED (2) head, plate washer (3) external diameter is definite like this: the external diameter loca of the line between luminous point and caustic surface (4) collar extension and the reflective surface of plate washer (3) is tangent.
As preferably, the pin (11) of LED (12) passes little prefocus cup (12) and the lamp socket (18) that is positioned in the middle of the prefocus cup cup (1) is fixedly connected with wiring board (15).
As preferably, the face that plate washer (3) contacts with LED (2) is provided with the fixedly cannelure of LED (2).
As preferably, little prefocus cup (12) is integral shape with plate washer (3), wholely passes through Bolt Connection with lamp socket (18).
The utility model is mainly on original one group of led light source basis, be provided with LED and little prefocus cup (12), increased the brightness of illumination, be provided with plate washer simultaneously with reflection action, the light that a feasible part scattered out originally reaches and effectively utilizes illuminated objects by the caustic surface of baffle reflection to the prefocus cup.This kind structure has effectively improved the space of LED flashlight lamp holder and the utilization rate of light, has characteristics such as simple in structure, that the brightening effect explicit costs is low, easily applies.
Description of drawings
