Description
Technical field
The utility model is related to light sources technical field, more particularly to a kind of double color temperature light sources.
Background technology
LED is gradually received, there are three types of the lamps and lanterns for being commonly used in illumination on the market currently used for general lighting by everybody
Colour temperature, cool white, just in vain, dim white.But as requirement of the people to illumination is higher and higher, the expansion of the use scope of LED,
It is even more thousand becoming for the requirement for illuminating colour temperature.The lamps and lanterns of light modulation toning are just complied with and life.Light modulation toning is mainly same
In one lamps and lanterns, dim white and just white two kinds of colour temperatures light source is loaded onto respectively.By changing the electric current of two kinds of light sources, so as to change two
The brightness ratio of the light source of kind colour temperature, so as to achieve the purpose that light modulation toning.In lighting of home, if larger beam angle
Degree, does not need to the light distribution elements such as lens and reflector, this mode can realize preferable dimming effect.But in some special photographs
Bright occasion, such as the flash lamp of camera, Projecting Lamp and auto bulb etc. are for the more stringent occasion of light distribution requirements, difference
What the light source of two kinds of different-colours of installation still made a strong impact.
In camera flashlamp illumination, a just white light source is typically installed as main light source 1, an amber is separately installed
Secondary light source 2 of the light source of amber color or dim white light as floor light, so as to reach the lighting effect of subject needs.But
It is, as shown in Figure 1, due to being two light source compositions, so there must be certain mounting distance D between two light sources, and one
As need D >=0.3mm, along with the wall thickness of the outline border of product, the wall thickness of product frame makes two light sources generally between 0.1-0.2
The distance between it is bigger, thus two kinds of light can not achieve and rub up well, and the light so as to cause subject surface is equal
Even degree can be short of.Requirement for light distribution is more harsh in headlight for vehicles illumination, when realizing cutting for distance light and dipped beam
When changing, with greater need for the consistency of light source installation site, it is impossible to be deviateed, otherwise can influence light angle and the position of light.
Utility model content
Technical problem to be solved in the utility model is：In order to overcome deficiency of the prior art, the utility model carries
For a kind of double color temperature light sources.
The utility model solves its technical problem technical solution to be taken：A kind of double color temperature light sources, including light source
Reflection cavity, the light source reflection cavity is interior to be equipped with floor, and the light source reflection cavity is divided into two parts by the floor, wherein, one
Light splitting source reflection cavity is fabricated to warm white color temperature light sources, and another part reflection cavity is fabricated to just white color temperature light sources, the warm white colour temperature
Light source and just white color temperature light sources are connect respectively by different pins with controller.It further includes and is arranged on light source reflection cavity back
Cooling fin, the warm white color temperature light sources and just white color temperature light sources share a cooling fin, and cooling fin is made of red metal material.Its
In, the colour temperature of general warm white color temperature light sources is controlled in 2800k-3200k；The colour temperature of just white color temperature light sources is controlled in 5500k-
7000k。
The utility model encapsulates the product of the light source of two colour temperatures respectively in same light source.Product structure be
In same light source reflection cavity, reflection cavity is divided into two parts by the side of body plate for increasing an interval, and some is fabricated to dim white
Temperature, some is fabricated to positive white temperature, to ensure the uniform mixing of different-colour.It is connect respectively not in two reflection cavities separated
Same pin, to realize the control of the adjustment of respective electric current and switching.
The thickness control of plate is coerced in 0.08mm-0.12mm, the thickness of floor far smaller than in the prior art different light sources it
Between mounting distance D, can be ignored, so as to ensure the accuracy of light extraction.
The beneficial effects of the utility model are：A kind of double color temperature light sources provided by the utility model, due to two kinds of colors
Light is placed in same reflection cavity, and two kinds of photochromic spacing are again small to can be ignored, therefore in the occasion for having light distribution requirements,
The consistency that can make light distribution after mixed light is more preferable；Two kinds of photochromic light sources can be jointly with a cooling fin, to reduce cooling fin
Waste, also more preferably realize product centrality.
