The present invention relates to a color temperature adjusting structure for an LED lamp which is produced at lower cost, and a color temperature of the LED lamp is adjustable based on using requirement.
A conventional tungsten light bulb has a color temperature at 2700 to 2400 K (i.e., warm light), a conventional fluorescent lamp has a color temperature at 5200 K (i.e., cold light), and a conventional LED lamp has a color temperature at 3000 K.
However, the conventional LED lamp is reduced its color temperature by increasing toner powder, thus causing high production cost.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.
The primary objective of the present invention is to provide a color temperature adjusting structure for an LED lamp which is produced at lower cost, and a color temperature of the LED lamp is adjustable based on using requirement.
Secondary objective of the present invention is to provide a color temperature adjusting structure for an LED lamp which prevents dust, scald, electric shock, and mosquito.
Another objective of the present invention is to provide a color temperature adjusting structure for an LED lamp which emits lights at a wide angle.
With reference to
a lamp holder 1 on which an LED light disc 11 is mounted; and
at least one protective cover 12 made of translucent material (such as PE or PP) and covered on the LED light disc 11.
In assembly, the LED light disc 11 is fixed on the lamp holder 1, and then the at least one protective cover 12 is covered on the LED light disc 11, such that when a number of the at least one protective cover is changed, a color temperature of the LED lamp is adjustable based on using requirement. For example, as a protective cover is covered on the LED light disc 11, the color temperature is reduced. In other words, the more the at least protective cover is, the higher the color temperature generates (i.e., the more the cold light occurs); and the less the at least protective cover is, the lower the color temperature generates (i.e., the more the warm light occurs).
Accordingly, the color temperature adjusting structure of the present invention is produced at lower cost, and the color temperature of the LED lamp is adjustable based on the using requirement. Preferably, the at least one protective cover prevents dust, scald, electric shock, and mosquito.
