Abstract

The utility model discloses an MR16-light-emitting diode (LED) bulb which comprises a base seat, a driving component, a heat radiating shell, an LED lamp panel and a protective sheet. A space is arranged in the base seat, the driving component is inserted into the space and is closely connected with the heat radiating shell, the heat radiating shell is molded by aluminum in an extruding mode, and the appearance of the heat radiating shell is in a hopper shape, heating radiating fins are arranged on the periphery of the hopper, heat radiating grooves are distributed among the heat radiating fins, and the outer periphery of the LED lamp panel is tightly attached to the inner edge of the hopper-shaped opening of the heat radiating shell. The MR16-LED bulb is characterized in that the contact area of the LED lamp panel and the heat radiating shell is 40% of the that of the LED lamp panel, surface mount device (SMD) LED patches are adopted on the LED lamp panel, the number of the SMD LED patches can be from 12 to 36, the SMD LED patches are evenly distributed, and transparent protective sheets cover outside. Due to the mentioned structure, heat is radiated easily, light rays are even and soft, the visual sense of human beings feels comfortable, and lighting effect is higher.

Description

The MR16-LED bulb

Technical field

The utility model relates to a kind of bulb, relates in particular to a kind of LED bulb.

Background technology

because LED has economize on electricity, the life-span speciality, environmental protection etc. advantage, so the bulb of modern Application LED is developed greatly, the LED bulb also continues to bring out various new products, substitute original incandescent lamp and Halogen lamp LED, work under the environment that but LED is not smooth in heat radiation or temperature is higher and can badly influence the life-span of itself, and cause optical attenuation too fast, so everybody is in innovation, think hard, make the heat dissipation technology scheme effectively with feasible, " high cooling type LED shot-light " as patent No. CN201120272703.1 introduced: " radiating subassembly by the raffinal manufacturing can effectively satisfy whole shot-light at the heat radiation needs of the course of work ", really play a role, the structure of also mentioning it " can effectively promote whole radiation response ", still, is the LED high-power bulb due to what adopt, and single power consumption is more than 0.5 watt, and heat is concentrated, and radiating effect is bad, and light is not soft yet.

Summary of the invention

The purpose of this utility model provides a kind of MR16-LED bulb that approaches with MR16 halogen lamp envelope size and light efficiency for the above-mentioned shortcoming of prior art.

The purpose of this utility model realizes by following technical scheme:

The MR16-LED bulb includes base, driven unit, heat-dissipating casing, LED lamp plate, screening glass.be provided with the space in described base, spatial interpolation enters driven unit, described driven unit is with two pins of external power supply, driven unit closely is connected with heat-dissipating casing, described heat-dissipating casing is aluminum extruded moulding, profile is infundibulate, be designed with radiating fin around bucket, be distributed with radiating groove between radiating fin, be used for distributing the heat that driven unit and LED lamp plate produce, described LED lamp plate neighboring is close on the inner edge of heat-dissipating casing bucket shape mouth, it is characterized in that: LED lamp plate and heat-dissipating casing contact area account for 40% of LED lamp plate area, good heat conduction is arranged, select special-purpose SMD LED paster on the LED lamp plate, quantity can be 12 to 36, and evenly distribute, described SMD LED paster model can be SMD3528, can be also SMD5050, SMD3014, SMD3020 etc., screening glass is stamped in the outside, screening glass is transparent.

Above-mentioned MR16-LED bulb technologies scheme can also be applied on the scheme that the GU10 based on halogen bulb transform the GU10-LED bulb as, selects special-purpose SMD LED paster on its LED lamp plate, and quantity can be 12 to 36, and evenly distributes; Also can be applied in the GX53 compact fluorescent lamp and transform as on GX53-LED illuminating lamp scheme, select special-purpose SMD LED paster on its LED lamp plate, quantity can be 12 to 60, and evenly distributes.

The beneficial effect that the technical solution of the utility model produces is:

Owing to having selected the special-purpose paster of SMD LED, overcome and adopted 1 or several high-powered LED lamps to steep oneself-meeting to produce the shortcoming of high heat, because single LEDs bulb power has more than 0.5 watt, cause unit are heat radiation difficulty, excess Temperature, affect LED life-span and luminescent properties, the utility model is selected SMD LED paster, monolithic power is uniformly distributed on lamp plate like this less than below 0.3 watt, and heat radiation is than being easier to, light is also even, the light that more sends due to SMD LED paster is softer than LED bulb, makes people's vision more comfortable, and light efficiency is also higher.
