Description

The flashlight light-emitting device

Technical field

The utility model relates to a kind of flashlight, refers to a kind of flashlight light-emitting device especially.

Background technology

Existing flashlight light-emitting device, as shown in Figure 2, in housing 4 leading portions, establish parabolic lens 5, and on the focus of parabolic lens 5, establish bulb 6, set firmly planar transparent glass 7 at housing 4 front ends, bulb 6 issued lights are scattering, and utilize parabolic lens 5 that bulb 6 issued lights are reflected into directional light and appear by planar transparent glass 7, but therefore bulb 6 utmost point power consumptions and can produce high heat, can improve as changing bulb 6 into the LED illuminator, but as shown in Figure 3, because LED illuminator 8 has direct projection emitting characteristics forward, even replace the electric power of bulb 6 the nearly LED illuminator 8 more than ten can be set, but these light are also bad through the spotlight effect of planar transparent glass 7.

The utility model content

Main purpose of the present utility model is to provide a kind of flashlight light-emitting device of spotlight effect preferably that produces.

To achieve these goals, technical solution of the present utility model is: a kind of flashlight light-emitting device comprises housing and LED illuminator, set firmly the LED illuminator in its middle shell leading portion, be installed with flat board in the housing leading portion, set firmly the LED illuminator on the flat board, the housing front end is installed with single convex lens.

After adopting said structure, set firmly flat board in the housing leading portion, set firmly the LED illuminator on the flat board, and the housing front end sets firmly single convex lens with ring cowling, single convex lens produces splendid illuminating effect with a plurality of LED illuminator issued light optically focused.

Description of drawings

Fig. 1 is the structure cross-sectional schematic of the utility model example;

Fig. 2 is a structure cross-sectional schematic of commonly using product;

Fig. 3 is the migrate structure cross-sectional schematic of LED illuminator of the bulb of commonly using product.

The specific embodiment

As shown in Figure 1, the utility model example comprises housing 1, LED illuminator 2 and single convex lens 3, wherein:

Be installed with flat board 11 in housing 1 leading portion, and on dull and stereotyped 11, set firmly LED illuminator 2 (this example is 5), and housing 1 front end is installed with single convex lens 3 with ring cowling 12.

Single convex lens 3 can produce splendid illuminating effect with a plurality of (this example is 5) LED illuminator 2 issued light optically focused.

Fig. 2 and Fig. 3 are for commonly using product, and the front is stated.

In sum, flashlight light-emitting device provided by the utility model, its structure innovation practicality can produce splendid illuminating effect with a plurality of (this example is 5) LED illuminator 2 issued light optically focused.
