Description
Technical field
The utility model relates to a kind of light fixture, especially relates to a kind of wide luminous intensity distribution MR16 LED light fixture.
Background technology
Existing MR16 light fixture all is to be main product with the narrow luminous intensity distribution that adds lens, promptly uses the mode of lens to come optically focused at the light source place, and such mode light efficiency is low, and light loss is big, has limited the application of its some aspect.And power supply is built-in, and power supply and the mode of the parallel placement of light source are unfavorable for the heat radiation of light fixture like this.
Summary of the invention
The utility model purpose is to the defective of prior art a kind of wide luminous intensity distribution MR16 LED light fixture to be provided.
The utility model adopts following technical scheme for realizing above-mentioned purpose:
A kind of wide luminous intensity distribution MR16 LED light fixture; Comprise heat radiation lamp body, light source board, it is characterized in that: it also comprises diffuser plate and pressure ring, and said light source board to diffuser plate has certain distance; Said light source board is placed on the bottom of said heat radiation lamp body front reflection cavity; Said heat radiation lamp body oral area is provided with installation step, and said diffuser plate reverse side is placed on the installation step of heat radiation lamp body oral area, and said pressure ring reverse side is provided with positioning step; The positive positioning step with the pressure ring reverse side of said diffuser plate is complementary, and by pressure ring it is pushed down; Said pressure ring sidewall is provided with buckle, and said heat radiation lamp body oral area arranged outside has the buckle slot that matches with buckle, and pressure ring passes through snap fit on the buckle slot of relevant position on the heat radiation lamp body.
The PMMA that said diffuser plate material is high mist degree, high transmission rate or PC or glass.
Said wide luminous intensity distribution MR16 LED lamp power is external.
Light source board to the step that diffuser plate is installed that install the said heat radiation lamp body of the utility model bottom has certain distance, and the LED of different colours can be set on the said light source board.Because the utility model utilizes PMMA, PC or the glass of high mist degree, high transmission rate but not lens make that the light that penetrates is more even, can't produce the hot spot of the traditional MR16 of picture; And the light that the LED of different colours sends can be in reflection cavity natural mixed light, promptly reflection cavity and mixed light chamber unite two into one, and make high-color rendering for light fixture and provide the foundation.And, prolong lamp life because the MR16 area of dissipation is not enough, and on-chip power will bring extra burden to the radiator of MR16, with the external junction temperature that helps to reduce LED of power supply, reduce the pressure of radiator heat-dissipation.

The specific embodiment
With reference to Fig. 1, Fig. 2; The utility model is the bottom that light source board 2 is placed on heat radiation lamp body 1 front reflection cavity; Diffuser plate 3 reverse side are placed on the installation step 5 of heat radiation lamp body 1 oral area; Positive positioning step 6 with pressure ring 4 reverse side is complementary, and by pressure ring 4 it is pushed down, and the buckle 7 that pressure ring 4 stretches out through the edge is fixed on the buckle slot 8 of the fixedly buckle 7 of relevant position on the heat radiation lamp body 1.
PMMA or PC or glass that said diffuser plate 3 materials are high mist degree, high transmission rate.
Said wide luminous intensity distribution MR16 LED lamp power is external.
Claims (3)
1. one kind wide luminous intensity distribution MR16 LED light fixture; Comprise heat radiation lamp body, light source board, it is characterized in that: it also comprises diffuser plate and pressure ring, and said light source board to diffuser plate has certain distance; Said light source board is placed on the bottom of said heat radiation lamp body front reflection cavity; Said heat radiation lamp body oral area is provided with installation step, and said diffuser plate reverse side is placed on the installation step of heat radiation lamp body oral area, and said pressure ring reverse side is provided with positioning step; The positive positioning step with the pressure ring reverse side of said diffuser plate is complementary, and by pressure ring it is pushed down; Said pressure ring sidewall is provided with buckle, and said heat radiation lamp body oral area arranged outside has the buckle slot that matches with buckle, and pressure ring passes through snap fit on the buckle slot of relevant position on the heat radiation lamp body.
2. a kind of wide luminous intensity distribution MR16 LED light fixture according to claim 1 is characterized in that: the PMMA that said diffuser plate material is high mist degree, high transmission rate or PC or glass.
3. a kind of wide luminous intensity distribution MR16 LED light fixture according to claim 1 and 2 is characterized in that: said wide luminous intensity distribution MR16 LED lamp power is external.
