Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-7, the present invention provides an embodiment: high efficiency three-dimensional lamp cup formula LED support, including metal support 2, the intermediate position of metal support 2 forms lamp cup 3 (the shape of lamp cup 3 designs according to the optical requirement, and through stamping forming), metal support 2 includes left half structure and right half structure, and forms dead slot 201 (the space of installing each component of LED chip) between left half structure and the right half structure, the internal surface of lamp cup 3 is provided with metal silvering plane of reflection 1, and the internal surface of metal silvering plane of reflection 1 has plated antisulfurization rete 4 (being called Miro material promptly) (as shown in fig. 1 and fig. 2).

In this embodiment: the metal support 2 is formed by a mould to just form the lamp cup 3, while the metal support 2 of the traditional framework has a rectangular section (as shown in fig. 5), a plastic bracket (as shown in fig. 6) is formed by a thermoplastic process or a thermosetting process, the lamp cup 3 is formed in the plastic bracket, and the reflecting surface is a metal silver-plated reflecting surface which is arranged at the bottom of the lamp cup 3 and belongs to diffusion type reflection.

After the LED chip is installed for lighting test, the copper metal silver-plated reflecting surface on the bottom surface is matched with EMC or PCT, and the silver reflectivity is 95% generally, but is 70-75% after vulcanization, so that the silver-plated surface can be vulcanized and light attenuation occurs;

the reflectivity of EMC is 80% (aging is firstly stable), while the reflectivity of PCT reaches 90-95%, but the reflectivity is about 70% after thermal yellowing, so the initial reflectivity is lower, and the PCT can be yellowed by heat, therefore, no matter the thermosetting process or the thermoplastic process, as long as a plastic material is used, the material aging phenomenon exists, and the light effect is influenced; therefore, in practical use, the initial light efficiency of the whole structure is not high enough, the light decay speed is obviously high and the like (as shown in fig. 7), the initial light efficiency of the traditional structure adopting the thermosetting process is 89%, the light decay efficiency after a period of time is 78%, and the light decay efficiency is reduced by 11%; the initial light efficiency of the traditional framework adopting the thermoplastic process is 94%, the light failure efficiency after the same period of time is 73%, the light failure efficiency is reduced by 21%, and the light failure speed is high; in addition, the initial luminous efficiency of the traditional structure adopting the Miro material and the PCT thermoplastic process is 94%, after a period of time, the luminous efficiency is 83% due to aging and failure of the material of the PCT, the light efficiency is reduced by 11%, and the failure degree is also obvious.

However, in the utility model, the plastic material is not used as the substrate of the metal silver-plated reflecting surface 1, but the metal material is used as the substrate of the metal silver-plated reflecting surface 1, and the lamp cup 3 is formed by stamping, so that the metal silver-plated reflecting surface 1 is a mirror reflection, belongs to a direct reflection type, has high reflectivity, does not contain plastic, and cannot be yellowed and have light decay; and the surface of the silver coating is subjected to anti-vulcanization treatment, so that the light decay speed is low.

Further, the metal bracket 2 is provided as a ferrous metal bracket 2.

Further, the metal holder 2 is provided as a copper metal holder 2.

Further, the metal bracket 2 is provided as an aluminum metal bracket 2.

Further, the metal holder 2 is provided as a Miro material holder.

Further, a base plate 5 is provided at the rear end of the metal holder 2, and the size of the base plate 5 is larger than that of the metal holder 2.

Further, the right half structure is provided with a cambered surface groove, and the height of the cambered surface groove is the same as that of the lamp cup 3.

In this embodiment: in order to verify the influence of the plastic bracket on the light effect, the plastic bracket is fixed in the metal support through a thermosetting or thermoplastic process, the plastic bracket is designed into a rectangular shape or various shapes, the plastic bracket fills a hollow groove and a cambered surface groove formed in the metal support, and the plastic bracket is contacted with the edge of the anti-vulcanization film layer 4 (as shown in fig. 3 and 4).

When the metal support 2 is fixed on the substrate 5, the empty groove 201 between the left half structure and the right half structure and two sections of arc surface grooves preset on the right half structure of the metal support 2 are filled with plastic and fixed, the filled thickness is just the thickness of the metal support 2, a complete lamp cup 3 structure is formed, the whole lamp cup is horn-shaped, the anti-vulcanization film layer 4 covers the inner surface of the lamp cup 3 without plastic positions, after the LED chip is fixed and the fluorescent powder is packaged, the light source emitted by the LED chip is reflected by the anti-vulcanization film layer 4, the reflectivity is high, and the whole light emitting efficiency is high;

the initial luminous efficiency of the Miro lamp cup support before injection molding is 98%, and the failure luminous efficiency after the same period of time is 95%, which is reduced by 3%;

the initial luminous efficiency of the Miro lamp cup support and the PCT (thermoplastic) is 94 percent, and the light failure effect after the same period of time is 83 percent and is reduced by 11 percent;

the reduction of the light effect value of the traditional framework of the Miro lamp cup support and the PCT (thermoplastic) and the thermosetting technology (EMC) is the same, but the initial light effect value of the Miro lamp cup support and the PCT (thermoplastic) is larger than that of the traditional framework of the thermosetting technology (EMC) by 5%, and the light failure value is still larger than that of the traditional framework of the thermosetting technology (EMC) by 5%, so that the integral effect is better than that of the Miro lamp cup support, and the Miro lamp cup support can be used before or after injection molding.

However, compared with the Miro lamp cup support and the Miro lamp cup support plus PCT (thermoplastic), the initial light effect of non-injection molding is 4% higher than that of injection molding, after the same period of time, the light effect of the Miro lamp cup support of non-injection molding is reduced by 3%, the light effect of the Miro lamp cup support of injection molding is reduced by 11%, and the influence on the light effect after the thermoplastic process is proved.

From the contrast numerical value of the initial light efficiency and the light failure efficiency of copper silver-plating + PCT, copper silver-plating + EMC, Miro lamp cup support + PCT and Miro lamp cup support, the initial light efficiency of Miro lamp cup support is bigger, and the light failure of same a period of time is slowest, therefore Miro lamp cup support has good light-emitting effect, and whole live time is long, has certain energy-conserving effect.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
