The technical proposal adopted by the utility model is that,

the utility model provides a ceramic substrate from taking boss, includes ceramic substrate and sets up the boss on ceramic substrate, and the boss makes for ceramic material, form LED installation inner chamber between boss and the ceramic substrate, be equipped with little lens mounting structure on the boss.

The boss and the ceramic substrate are mounted on the copper substrate, a cavity formed between the boss and the ceramic substrate is used for mounting an LED chip, the boss is equivalent to a small lens support, and the small lens mounting structure on the boss is used for mounting small lenses, so that the small lenses and the LED chip form a one-to-one correspondence relationship and the small lenses and the LED chip keep a certain distance. The utility model discloses an adopt one from the ceramic substrate who takes the boss, reduced one process in the production process for the production cycle of product shortens, improves production efficiency, adopts the boss of ceramic material simultaneously, and the radiating effect is better, is favorable to improving LED's light efficiency and life.

Further, the boss is integrally formed with the ceramic substrate.

The integrally formed structure reduces the mounting steps of the boss and the mounting procedures of the product.

Furthermore, the boss comprises a plurality of sub-bosses, and gaps are formed among the sub-bosses.

Gaps are formed among the sub bosses, so that the ventilation of the LED chip cavity is facilitated, and the heat dissipation efficiency is improved.

Furthermore, the number of the sub-bosses is two, and the sub-bosses are of an L-shaped structure.

Furthermore, the inner side surface of the boss is arc-shaped, and/or the bending part of the outer side surface of the boss is arc-shaped.

The circular arc design of boss medial surface is for the circular bottom surface of laminating the small lens, and the installation of the small lens of being convenient for is firm.

Furthermore, the top end of the boss is in a step shape and comprises a first step surface arranged close to the inside and a second step surface arranged close to the outside.

The boss top is the echelonment, and the upper surface includes first step face and second step face, and first step face is close to the boss inboard, and the second step face is close to the boss outside, and first step face height is less than second step face height. The utility model discloses a be the boss on echelonment top for the small lens installation is firm or when glue is not dry in the installation, and the small lens position can not take place to remove.

Further, the distance between the first step surface and the ceramic substrate is 0.5 mm-0.8 mm.

The distance between the first step surface and the ceramic substrate is set to be the same as the distance between the microlens support and the substrate in the prior art.

The utility model also provides a LED luminescence unit, include from the ceramic substrate of taking the boss, locate the copper base plate under the ceramic substrate, locate boss installation inner chamber's LED chip and locate the little lens on the boss.

The mounting structure of the LED light-emitting unit is as follows: a copper substrate is installed below the ceramic substrate with the boss, the ceramic boss is installed above the copper substrate, an LED chip is installed in an inner cavity formed by the ceramic substrate and the boss, and small lenses are installed on the upper surface of the boss. The boss is equivalent to a small lens support, the small lenses and the LED chip form one-to-one correspondence, and the small lenses and the LED chip keep a certain distance. The LED light-emitting unit is adopted, the process of additionally installing the small lens support is reduced, the production period of a product is shortened, the production efficiency is improved, the heat dissipation effect is improved, and the improvement of the luminous efficiency and the service life of an LED are facilitated.

Compared with the prior art, the beneficial effects of the utility model are that:

1. ceramic substrate and boss integrated into one piece have reduced the process that needs additionally install the little lens support on the copper base plate for the production cycle of product shortens, improves production efficiency.

2. The material that the boss adopted is ceramic material to have the breach between the sub-boss, play better ventilation radiating effect, be favorable to improving LED's light efficiency and life.

3. The boss with the stepped top end is adopted, so that the small lens is stably installed or the small lens cannot move when glue is not dried in the installation process.
