The specific embodiment

Below in conjunction with drawings and Examples the utility model is elaborated.

Consult Fig. 1 ~ Fig. 3, a preferred embodiment of the utility model led lamp comprises a lamp socket 2, LED lamp source 3, a control chip 4, and a diffusion lampshade 5; Wherein, Fig. 1 is the sectional perspective schematic diagram of the utility model led lamp, and Fig. 2 is the cutaway view along a-a hatching line among Fig. 1, and Fig. 3 then is the electrical connection schematic diagram of this LED lamp source 3, control chip 4 and an external power source 6.

This lamp socket 2 can be electrically connected with this external power source 6, has an internal face 21, and this internal face 21 defines an accommodation space 211 with an opening that is in communication with the outside 212.

This LED lamp source 3 is placed in this accommodation space 211, and is electrically connected with this lamp socket 2, has a LED bulb 31, and a lampshade 32.

This LED bulb 31 can produce colour temperature between the light of 4900 ~ 5500K when accepting electric energy, this lampshade 32 covers are established this LED bulb, and optionally the wavelength that sends from this LED bulb 31 of filtering is light below the 380nm.

Detailed says, this LED bulb 31 is to get after a plurality of LED crystal grain 311 encapsulation, and described LED crystal grain 311 can produce colour temperature between the light of 4900 ~ 5500K when accepting electric energy, because the photochromic selection of described LED crystal grain 311, wavelength are arranged in pairs or groups, method for packing is known by the present technique dealer, therefore no longer add to give unnecessary details.

This lampshade 32 is made of transparent material, and cover is established those LED crystal grain 311 and can be with the light filtering less than 380nm of the wavelength that externally sends from described LED crystal grain 311.Specifically, this lampshade 32 is to process in advance to process when producing to make it possess the filtering wavelength less than the function of the light of 380nm.Its processing method can be the known filter of the front interpolation of lampshade shaping or the rear mode that sees through plated film that is shaped is reached, owing to non-pattern characteristics place of processing method, so no longer this states.

In present embodiment, this LED bulb 31 is rear the getting of LED crystal grain 311 encapsulation of sending different wave length section scope with a plurality of, this lampshade 32 then is that cover is established described LED crystal grain 311, therefore, after receiving electric energy, described LED crystal grain 311 produces colour temperature between the light of 4900 ~ 5500K, and is the following person of 380nm through this this light source medium wavelength of lampshade 32 filterings further, and the wavelength of light scope that makes this LED lamp source 3 externally send is between 380 ~ 680nm.In addition, being noted that this lampshade 32 also can cooperate covers at this each LED crystal grain 311.

This control chip (chip) 4 is electrically connected with this LED lamp source 3 and this external power source 6 respectively, circuit by these control chip 4 these diode lights sources 3 of control, and make this diode lights source 3 produce 4900 ~ 5500K between colour temperature, in this preferred embodiment, the colour temperature of this LED lamp source 3 is 5400K, and possesses color rendering and be at least 90.

This diffusion lampshade 5 is made of the light-permeable material, removably be connected with this lamp socket 2 and seal this opening 212, utilize this diffusion lampshade 5 can relax the dazzling problem of light direct beam that this LED lamp source 3 sends and can be with these LED lamp source 3 diffusions, and promote the light-emitting uniformity of this LED light fixture.

When the electric energy that is provided by this external power source 6 is provided those LED crystal grain 311 of the utility model, just can convert the electric energy that receives to luminous energy outwards sends, and the light that sends from those LED crystal grain 311 is by this lampshade 32 time, wavelength can can't pass through this lampshade 32 less than the light of 380nm, therefore, this LED lamp source 3 of the utility model can reduce UV light that known diode light-source sends to the injury of human body.The colour temperature of utilizing this control chip (chip) 4 then can further make this LED lamp source 3 produce is between between 4900 ~ 5500K, and possess simultaneously color rendering and be at least 90 characteristic, the illumination of adequate brightness is provided whereby and can has cosy effect concurrently.

Consult Fig. 4, Fig. 4 is that the light of the utility model LED lamp source 3 generations is through the result of prism dialysis.The optical wavelength sent of LED lamp source 3 of the present utility model is encompassed between 380nm to 680nm wave band as shown in Figure 4, not only can reduce short wavelength's UV light, and its wave-length coverage meets the optical source wavelength that the occurring in nature sun provides; And can confirm more that through the analysis result of colorimeter (colorimeter) chromaticity coordinate and colour temperature that this novel LED lamp source 3 produces are respectively CIE 1931 (0.3633,0.3970) and 5400K.

Although what specify is that this specification divides the aspect that has disclosed a kind of light fixture in other Fig. 1,2, is not limited to this, also visual user's the demand use of arranging in pairs or groups of other forms of light fixture.

The utility model utilization can be sent the LED bulb 31 of full spectrum of wavelengths as the light source of led lamp, it is consistent with the optical source wavelength scope of occurring in nature sunshine, therefore can provide more near natural light irradiation, comfortable and tireless lighting environment, and by establish at these LED bulb 31 loam cakes one can the filtering wavelength less than the lampshade 32 of the light below the 380nm, therefore send wavelength from this LED bulb 31 and just can or not do not passed this lampshade 32 and outwards send by filtering by this lampshade 32 time less than the light of 380nm, and then can avoid known because use UV light that full-spectrum LED lamp produces to the shortcoming of human exposure; In addition, because also can making by the control of this control chip (chip) 4 colour temperature that this LED lamp source 3 sends between between 4900 ~ 5500K and possess simultaneously color rendering, the utility model is at least 90 characteristic, illumination with adequate brightness not only can be provided and can have cosy effect concurrently, so really can reach the purpose of this utility model.
