Abstract

The present invention provides portable color checking or matching devices each comprising an LED light source with a color rendering index (CRI) of not less than 95%, a supporting unit securely housing the LED light source, a lens attached to the supporting unit and covering the LED light source, a power source contained in or attached to the supporting unit.

Claims

1. A portable device, comprising an LED light source with a color rendering index (CRI) of not less than 95%, a supporting unit securely housing the LED light source, a lens attached to the supporting unit and covering the LED light source, a power source contained in or attached to the supporting unit.

2. The device of claim 1, wherein the LED light source provides has a CRI of not less than 97%.

3. The device of claim 1, wherein the LED light source provides has a CRI of not less than 98%.

4. The device of claim 1, wherein the LED light source provides a color rendering index (CRI) of not less than 99%.

5. The device of claim 4, wherein the LED light source is a Chip-on-Board (COB) LED.

6. The device of claim 5, wherein the LED is a Surface-Mounted-Device LED.

7. The device of claim 6, wherein the LED is a lower power but high lumen LED.

8. The device of claim 1, wherein the LED has a luminous efficiency of at least 30 lumen/watt.

9. The device of claim 8, wherein the LED has a luminous efficiency of at least 50 lumen/watt.

10. The device of claim 9, wherein the LED has a luminous efficiency of at least 75 lumen/watt.

11. The device of claim 1, wherein the lens is made of a transparent and reinforced material that is resistant to organic solvent and high heat.

12. The device of claim 11, wherein the lens is made of or comprises reinforced glass, borosilicate glass, Grilamid TR 90, or polymethyl methacrylate.

13. The device of claim 1, wherein the power source is a rechargeable or non-rechargeable battery.

14. The device of claim 13, wherein the power source is a rechargeable lithium battery with a capacity of at least 1800 mAh.
