Abstract
A high-brightness luminous body for traffic signal, warning, car and billboard is composed of casing. Fresnel lens, parabolic cavity and light generator.
Description
A kind of high-brightness luminous body structure, fields such as its suitable traffic lights, warning lamp and automobile, billboard.
Common in the prior art in order to increase the light-source brightness of diode, on diode, be provided with parabolic shape or be referred to as bowl-shape refractile body, in order to increase its brightness, but from technology cost aspect, cost is higher, and need on bowl, to carry out coating film treatment, and structure is owing to be roundel, assembling is also comparatively complicated.
The inventor improves according to the weak point that exists in the prior art, makes its structure more become to rationalizing, and the brightness of light source increases, and has energy savings, removes the bowl-shape refractile body of prior art, and this is unique goal of the invention of the inventor.
Technical scheme of the present invention is by a shell body, this shell body bottom is provided with pin, in order to fixing luminous body structure, be plane on the top of shell body, and at the plane Fresnel Lenses that is carved with, shell body inside is embedded with an inner chamber body, this inner chamber body is parabolic shape refraction chamber, its top and Fresnel Lenses join, and its underpart and four human hair combing waste optical diode stamen grains join, and this illuminator sets firmly in the circuit board.
For explanation that can be detailed technology of the present invention constitutes, see also shown in the following accompanying drawing, further instruction is as follows:
Fig. 1 is the stereogram of high-brightness luminous body structure of the present invention;
Fig. 2 is the cutaway view of high-brightness luminous body structure of the present invention.
See also Fig. 1, Fig. 2, the lower end that can very clearly find out square shell body 1 is provided with four pins 11, the inwall that is provided with Fresnel Lenses 4 and square shell body 1 in the upper surface of square shell body 1 is embedded with a parabolic cavity 3, the top of this parabola cavity 3 and Fresnel Lenses 4 join, bottom and illuminator 2 join, the luminous point of illuminator 2 and paraboloidal focus are same point, the light that illuminator 2 sends is transformed into directional light and penetrates after parabolic reflector, the focus of Fresnel Lenses 4 is a same point with the luminous point of illuminator 2 also, the footing of illuminator 2 and wiring board 5 welding one.
Can find out that by as above structural design the L1 among its illuminator such as Fig. 2, ray are that the directional light after parabolic reflector becomes scattered light through Fresnel Lenses 4 refractions again, and L2 is the directional light that illuminator 2 becomes after Fresnel Lenses 4 refractions.Therefore, the present invention is high-intensity luminous body structure.Must test by experiment and learn: (luminous intensity of 12.5mm * 12.5mm) is generally 40cd to 70cd, and middle degree of constant volume is 70cd to 100cd, and high brightness is more than the 100cd for assembly.
In sum, the inventor has reached the inventor's goal of the invention, and a kind of new light-source structure is provided by the as above enforcement of technical scheme.
