Above-mentioned traditional LED bulb, because material and manufacturing process are limited, its colour temperature is higher, such as common cold white LED lamp; But under above-mentioned light reading indoctrination session that eyes are produced is tired, people wish to throw light on the LED of warm white thus, and under the light of low colour temperature high-color rendering study and work; For this purpose, present way generally is in the manufacturing company of LED white light, applies the YAG(cerium with blue chip) generate white light, and go for warm white, then need to add some fluorescent material, like this then will inevitably affect the output of light efficiency, be difficult to satisfactory to both parties.

In view of this, the inventor has this case to produce for the defects further investigation of existing LED bulb then.

The utility model content

The purpose of this utility model is to provide a kind of bulb of the novel LED of adjusting colour temperature, can't allow simultaneously light efficiency and all good problems of colour temperature to solve in the prior art LED bulb.

In order to reach above-mentioned purpose, solution of the present utility model is:

A kind of novel bulb of regulating the LED colour temperature, comprise lamp holder, radiating module, light source module and lampshade, this light source module links to each other with the civil power input by lamp holder, and this radiating module links to each other and distribute heat with light source module, and this lampshade then is located on the light source module; Wherein, this bulb also comprises the optical filter that is arranged between light source module and the lampshade, and this optical filter has optical filtering section and hollow-out parts, also is formed with the manipulation end of aliging with optical filtering section or hollow-out parts for the LED crystal grain of determining light source module on this optical filter.

Further, the LED crystal grain in this light source module is intervally arranged in the form of a ring, the optical filtering section of this optical filter also in the form of a ring the interval arrange, this hollow-out parts also in the form of a ring the interval arrange and each hollow-out parts between adjacent optical filtering section.

Further, this light source module is fixed on the radiating module by the first screw, and the center of this optical filter is fixed on the radiating module by the second screw, and this second screw passes the mesopore of light source module, also is provided with pad between this optical filter and the light source module.

Further, this radiating module is the aluminium shell.

After adopting said structure, the bulb of a kind of novel LED of the adjusting colour temperature that the utility model relates to, its optical filter by between light source module and lampshade, arranging, so the user can allow according to current user demand optical filtering section or hollow-out parts and LED grain alignment, thereby determine the mode of operation of current bulb, when optical filtering section and LED grain alignment, current bulb is in the reading mode of learning, and when hollow-out parts and LED grain alignment, current bulb is in the general lighting pattern.So, compared with prior art, people can change the colour temperature of bulb according to actual needs, thus the effect that reaches illumination and learn to take into account; In addition, the utility model also has simple, with low cost characteristics.
