Description

A kind of LED Lamp cup

Technical field

The utility model relates to a kind of light source, refers in particular to a kind of LED Lamp cup.

Background technology

Along with the increase of LED light efficiency, price descends, and the application places of LED expands general lighting to by decorative lighting, backlight, indicator lamp, thereby will replace traditional incandescent lamp, halogen tungsten lamp, electricity-saving lamp etc.Oneself various types of LED Lamp cups occur on the market.Because the brightness of a LEDs is not enough, to take in a Lamp cup or in parallel or series connection plurality of LEDs increases brightness, Lamp cup is generally plastic rubber material, and She Ji defective is exactly that light efficiency is not high like this, and it is bad to dispel the heat, and influences the long-life of LED.Along with the technology maturation of great power LED, adopting a LEDs to reach lighting requirement will be a kind of trend.As everyone knows, incandescent lamp etc. adopt the radiant type radiating mode, and the LED light fixture is the conduction-type heat radiation, and solving heat dissipation problem also will be the prerequisite that realizes LED generalization illumination.

Summary of the invention

The purpose of this utility model is to release a kind of LED Lamp cup, a built-in high-power LED light source, adopt the radiating shell of metal material, wiring board is built in the insulation shell and adds a cover insulation board, line security, reliable, stable, design has collector lens on the led light source, and arrow beam of light increases light efficiency and brightness.Also can as required the led light source partial design be regulated the light projector direction for turning.

The technical solution of the utility model is as follows:

A kind of LED Lamp cup, comprise housing, the wiring board of in housing, settling, the lens of putting on led light source and the led light source, described housing comprises radiating shell and shell of lamp base, wiring board is built in the shell of lamp base and with insulation cover plate and seals up, place heat sink on the insulation cover plate, led light source is a great power LED, is fastened on the heat sink, and the led light source top adds lens.

Radiating shell is a metal material, and design has fin or louvre or radiating groove around it.

Lens can add lens cover by being adhesively fixed at the radiating shell openend or on lens, lens cover is by being bonded in the radiating shell openend, the lens cover edge designs has louvre, lens cover can be designed to a billiard table chamber, in the billiard table chamber, add spherical shell and following spherical shell, at last spherical shell and built-in led light source of following spherical shell and lens, be protruding ball bottom the following spherical shell, match with recessed ball on the heat sink.

Shell of lamp base has lamp base, and lamp base is designed to pin type or screw socket type or the bayonet type of GU10 type or MR11 or MR16.
